Afghanistan is a country in Central Asia that has borders with Iran, Pakistan, Kyrgyzstan, Uzbekistan, and Tajikistan. Also, the country has a very short border with China that has resulted from quite a strange deal between the British and the Russian Empires in the 19th century. Throughout the 1970s Afghanistan used to be quite a popular destination as the hippies would travel to India more than ever. Kabul, the Afghan capital city used to be a very hip place to hang out and party back in that period. Things have dramatically changed for the Afghan tourist since then.
Everything started in 1979 when the Soviet Union invaded and occupied the country. Ten years later the Soviet army was forced to leave Afghanistan as the anti-communist Mujahidin forces, which were supplied and trained by the United States, Saudi Arabia, Pakistan and others. The Islamic Taliban movement has taken over most of the country and there is continuous violence among the various Mujahidin factions. Also, besides all the political problems the Afghan population is also confronting with continuous civil strife, enormous poverty, poor infrastructure and widespread live mines.
All these make Afghanistan an unpopular tourist destination and only the brave and the adventurous tourists venture outside Kabul or the main cities. On the other hand, the Afghan population is not particularly fond of foreigners, thus tourists are not very much welcome inside the country. Most tourists who choose to visit Afghanistan are attracted towards crossing the Khyber Pass from Pakistan and go on to Jalalabad. It is important to note that the Jalalabad city is quite safe, but the border is a little more dangerous as it is Taliban country. Once here you can go on the road that leads to Kabul, but you have to keep in mind that it is quite dangerous to venture by yourself and that attacks on foreigners have very much increased since 2003. You can however choose to travel escorted by armed Afghan people who offer their services for protection. A safe way to visit the country is to fly to Kabul and visit all the other cities by air. It is not recommended to wander around the country and the cities in the South and East should be avoided. However, cities like Kabul, Mazar-i-Sharif, Heart and a few others in the North-West area are considered to be relatively safe for visitors. Please take into consideration the fact that many governments declared that traveling to Afghanistan is not safe, although it is an enchanting country with exciting culture and history.
Kabul is the capital city and is located in the center of the country. The city is considered to be Afghanistans major tourist attraction due to its day and night life, culture and sites. It is definitely the best choice to explore as, although it is considered a dangerous city in a dangerous country, the safety rates are quite high in comparison with the rest of the country. Some of the biggest attractions here is the Kabul Museum and the famous Garden of Babur. Also, the Valley of Paghman is a very beautiful place to visit, but beware that there are no busses to take you there.
Herat is another tourist attraction in Afghanistan and it is very close to the Iranian border, being the second biggest city in the country. It has always been considered a relatively safe place for travelers. Even though the Irano-Afghan relations have dropped to an all-time you can still cross the border from Iran. You will need valid passports and visas, though a visit to the State of Israel will prevent you from entering Iran. The tourist attractions in Herat are the huge defensive walls and earthworks that have been preserved since ancient times. The Friday Mosque is dating since the 10th century BC and the Gazergah monastery and mausoleum is about one thousand years old. One very interesting thing about Herat is the fact that it hosts the first women only university world wide. Today, Herat is the most important Afghan industrial center and it is also considered to be the safest city in the country.
Mazar-i-Sharif is another major tourist attraction in Afghanistan. The translation of the citys name is something like Tomb of the Chosen One and it comes from the fact that the city is hosting the tomb of Hazrat Ali, a very close relative of the prophet Mohammad. The Blue Mosque is also another tourist attraction in this city.

北京严打涂料业“傍名牌”-“九龙华润涂料”涉嫌侵权遭查处
“傍名牌”已成为扰乱我国市场经济秩序的重要问题，也是正在进行的整顿和规范市场经济秩序的热点和难点。在国家工商总局针对全国范围内的“傍名牌”不正当竞争行为进行严厉打击的要求下，日前，北京市工商行政管理局对涂料行业出现的“傍名牌”商品进行一次突击检查，“九龙华润 ”等多种涂料品牌因涉嫌“傍名牌”被查处。 在此次专项行动中，北京房山区工商分局良乡工商所根据举报，在永林建材城和裕恒通家具建材购物中心发现一种“九龙华润”涂料。这种涂料在名称、包装和商标上都与“华润漆”相似，涉嫌侵犯广东华润涂料有限公司所拥有的“华润漆”注册商标专用权和“华润漆”外观设计专利权。工商局执法人员依法对这些涉嫌商标侵权的“九龙华润”涂料予以暂扣，并立案查处。 将行业中的知名商标注册成自己的公司商号，以便混淆公司名称与品牌名，试图使消费者误以为自己的产品与著名品牌有一定关联，从而扩大销路，获取利润，这种现象被业内称为“傍名牌”。在我国涂料行业，“傍名牌”现象由来已久。作为涂料行业中的领军品牌，“华润涂料”也成了众多“傍名牌”企业的主要目标。“华润漆”是广东华润涂料有限公司的注册商标，2006年，被相关部门认定为“中国驰名商标”。长期以来，诸如“九龙华润”这样打着“华润”字号的“伪华润”涂料品牌多达数十个。这些“伪华润”在市场上大量出现，让不知情的消费者误以为他们是广东华润涂料有限公司的分公司或者在广东顺德以外的生产基地，甚至还有的品牌以次充好，在市场上销售质量低劣的产品，从而使华润涂料的经济利益和企业形象受到巨大损失。 据悉，在此次专项行动中，北京海淀区工商分局、房山区分局、大兴区分局在各辖区内的建材市场共查获“九龙华润”、“英国华润”、“华润新世纪”、“润美”、“华润漆王”、“华润第二代”、“华润大赢家”等涉嫌侵权的木器漆共200余组，涂料300多公斤，执法人员对所有被查获的商品依法予以暂扣，目前案件正在进一步处理之中。 据了解，除“华润漆”以外，诸如“立邦漆”、“华隆涂料”、“嘉宝莉漆”等多个涂料市场的名牌产品都有过被“傍”的经历。这些知名企业纷纷表示，“傍名牌”行为使他们深受其害，希望工商部门的专项整治行动能够取得有效的成果。 据悉，北京市工商局针对涂料行业的专项整治行动由各区工商所对其辖区内的违法经营者进行查处。行动结束后，有关部门将对侵权行为进行立案审查。如果这些品牌的“傍名牌”不正当竞争行为成立，则会受到严厉惩罚。

Things you should know before buying digital camera
If you are looking to buy a digital camera, you should properly educate yourself about all the different aspects of digital cameras. There are many types of digital cameras out there all with different features, so you should first ask yourself a few questions before actually spending several hundred dollars on your big purchase.
1. What exactly are you going to be using the camera for?
2. Will it be used as part of your job or will you use it for recreational purposes?
3. Should you buy a mini digital camera or should you look for a standard size digital camera?
4. How much money are you willing to spend and what is your budget for your digital camera expenses?
Remember, the camera itself is just one part of the cost; you still need to pay for batteries, computer cables, and memory and media types for storing your pictures and video.
Some other things you should keep in mind when trying to select a suitable digital camera are the weight of the camera and the look and feel of the digital camera. If you need to take the digital camera with you during your daily routine or job, you should make sure that it will not get in the way of whatever it is that you need to do. Another important aspect of digital cameras that you should be aware of is the zoom function.
There are two basic types of zoom, optical zoom and digital zoom. Optical zoom is the type of zoom where you press a button and the lens physically moves around in order to zoom in or out. This is the zoom method that you are probably the most familiar with. The other type of zoom is known as digital zoom.
Digital zoom is a new method of zoom that has been introduced with the invention of digital cameras and does not rely on any moving parts. It basically crops the photo you take and then enlarges it, which in effect creates a type of optical zoom effect. Generally speaking, you should try to use optical zoom over digital zoom, since digital zoom reduces picture quality by a great deal in most cases.
If the reason that you want to buy a digital camera is for recreational purposes only, you should consider the option of buying a mini digital camera. Generally speaking, mini digital cameras are not as powerful as your standard size cameras, but they have several advantages. Obviously, they are portable and very convenient to bring along with you on your travels. Most mini digital cameras will fit in your pocket without a problem, whereas standard size digital cameras can be quite bulky and awkward to carry around at times.
Another benefit of having a mini digital camera is the fact that they are great to show off to your friends and family. They make great conversation starters and if anyone sees you taking a picture with a tiny digital camera, odds are that they will stop to chat with you a bit about the price and specifications of your camera. Finally, mini digital camera accessories are a bit cheaper than standard sized accessories so you can expect so save a bit of money when buying your accessories.

Vital Tips for Document Scanning Software Buyers
The requirement to save paper and control the management of workflow documents and images continues to be driven by two main methods: managing costs through efficiency and managing environmental concerns through technology. The need is therefore continuous and ongoing, to ensure the correct acquisition of document scanning software with functions which fit the purpose. This summary highlights some important considerations when buying such software.
Categories of Document Scanning Software
Document scanning solutions fall in to one or more of the following categories by function. These are
1) Ad-hoc scanning of individual documents into computer files
2) Desktop batch scanning of documents to network files or to a document management system
3) High-volume, multi-user scanning of documents to document management system
4) Automated indexing of documents from multifunctional printers, network scanners or distributed capture
5) Applications which automate data entry tasks using handprint recognition and dynamic Optical Character Recognition (OCR) to capture data from images
Which Scanning Software Features?
The key to the best practice and most efficient document scanning is to specify as many automation features as possible to eliminate manual indexing and at the same time make all documents fully searchable.
An excellent way to achieve this is with barcodes. Barcodes can be recognised with a very high rate of speed and accuracy and a minimal possibility of false positives.
Another way is via Optical Character Recognition (OCR) which can be used to read indexes from machine print on scanned images. It's not as quick as barcodes, and the recognition rate is not as high, but it has the advantage with documents that were not designed with scanning in mind.
An efficient user-friendly interface design will also save you time in setting up, training staff and supporting the document scanning application. Clearly, staff will respond better to any work pattern changes with a more efficient interface for their daily work. For this reason the user experience must be a paramount consideration..
Other Key Scanning Software Features
Features and areas requiring attention and comparison between software brands are:
License Type: Is the license server or workstation based? Do any monthly page limits apply?
Platforms: Presently, almost all batch scanning system is limited to the Windows user environment.
Export Capabilities: How is index data exported? Keywords can be used to organize images into logical folders and filenames on a network, for example. Alternatively it can be exported to delimited text files for import into other software systems. Or again, it can be added directly to an ODBC or OleDB database.
Scanner Support: Almost all scanners support TWAIN drivers. These days, ISIS drivers are also supplied with most document scanners available. Real-time image enhancement on scanned images is supplied by Kofax - native support for Adrenaline image processing boards.

Document Scanning and Management Systems: A Review
Document management systems let businesses store and search digital documents, whether they are scanned images or MS Office documents, PDF files or CAD drawings. Some have a web-based interface to let you view files online, while others have an installed client application for better speed and functionality. All of these solutions require a central database and storage server to hold the files and index information used for searching.
These document management systems require a few days in planning, installation, configuring and training. This is definitely time well spent, ensuring that a correct and optimal implementation at the outset will revolutionise the way in which any company works with its records.
This review highlights a range of proprietary document scanning and document management software, with key functions which they offer.
Systems to Store, Search and View Documents
PaperVision by DigiTech and CompuThink's ViewWise both provide fully featured, HIPAA-compliant (Health Insurance Portability and Accountability Act) document management systems. Both of these systems can grow with company needs, and are affordable enough for small businesses yet powerful enough for large corporations too. Each offers some benefits that the other does not.
To take PaperVision first: this software suite includes a customisable application for searching and viewing, as well as a web interface. PaperVision also has workflow and report management modules which boost any return on investment by allowing the automation of document processes and eliminating pre-printed forms.
A "lite" version called PaperVision XPress offers a similar search interface as PaperVision Enterprise, but comes in at a lower cost, without the extra scalability, security and options.
The other fully featured in-house system featured here is ViewWise. This system is unique in that it is Java-based and can run on Windows/SQL Server as well as Novell, UNIX and Linux operating systems and Oracle database servers. ViewWise also has several key differences in the layout of its user-interface that many users prefer. This includes a folder view for browsing documents.
For a simple, low cost scanning front end for these document storage and retrieval systems, an interesting product is SimpleIndex ' which complements both. SimpleIndex is designed to interface directly with both PaperVision and ViewWise, and so provides a simple, low-cost automatic scanning front-end.
In fact, SimpleIndex also includes its own low-cost searching and viewing application that can be used for basic document management tasks, and so SimpleIndex can be used as a standalone document management system, or added to allow the search and viewing of documents on other workstations.
Another document management product is DocuLex WebSearch. This system is a different in that it can automatically index all documents folder contents, similar to the way in which Google Desktop operates. Networked users are able to search on values in filenames, file properties or document contents. Additionally, users can access files via a website ' a big advantage for remote workers operating outside the confines of the office building.

5 Tips to Help You Buy a Digital Camera
Buying a digital camera can turned into a difficult task. With hundred of cameras to choose from, its easy to get confused. The key to finding the perfect camera for your budget is to know a few things about what youre looking for. Use these tips to help you navigate through the world of digital photography and by the camera thats perfect for you. Decide on a Purpose: Why are you purchasing a camera? Is it for digital memories or masterpieces? In other words, are you buying a camera to take pictures of for yourself or are you taking pictures for professional reasons. There are many great compact cameras that are easy to travel or keep at home for spur of the moment pictures. There is also a great selection of cameras that are made for more professional or artistic photography. The more professional cameras are more expensive and will often have features you dont need and will never use. Shop Around: Different retailers will offer different specials, packages, and prices, so check out different stores and do some comparison shopping. Shopping around doesnt mean you have to drive from store to store; most major retailers will have websites listing products, prices, and any specials they may have. Use the money you saved to buy accessories that will come in handy. Digital or Optical: When purchasing your camera you will need to choose between optical and digital zoom. When at all possible, choose a camera that offers optical zoom. Digital zoom is a computer based image of what your picture should look like when you zoom in. This often creates a blurry or grainy effect when you try to enlarge pictures. Optical zoom provides a true image of the whether your zoom in or zoom out. Base your purchase on your purpose. If you are a photographer and you need to be able to zoom in and out while keeping a clear picture, choose the optical zoom. How Much Media do You Need: Your camera will most likely use up the available media memory. This is a case of bigger is definitely better. Even if you purchase a camera with a lot of memory its still a good idea to purchase at least one memory card. Again, if youre planning on taking professional quality pictures, you definitely will need to purchase back up memory. Higher quality pictures or pictures with more megapixels will take up more memory. Look for Pre Programmed Scene Modes: Scene modes are setting that prepare your camera for certain conditions. For example, you will be able to pick scene modes that will improve pictures taken at night or action pictures like sporting events. These modes are especially helpful for individuals who are just beginning their journey through digital photography. In a way, pre programmed scene modes are digital camera training wheels to help you learn to take great pictures. With a simple flick of a switch or turn of a knob youll be able to improve your pictures depending on your setting.
What is Computer Memory?
Many people ask themselves "What is computer memory?" and with good reason. Computer memory can be a difficult concept to understand for most people. There are only two types of memory Ram memory and hard drive memory.
What is Computer Memory? Ram memory
"what is computer memory?" in reference to RAM memory. Ram memory is also known as random access memory and it stores information that the processor on your computer uses. Ram memory is made up of a module that has integrated circuits on it. The integrated circuits store information on them and that information can be accessed by the CPU in any way or form, that is why it is called random. The memory can be accessed in any way without moving or changing the module in any way. The only problem with RAM memory is that the moment the computer is shut down that memory is lost.
Unlike data previous data storage methods ram memory can pull data from any location within the circuits and other methods like tapes and magnetic disks require physical amount of the data or an optical reading unit.
Ram can also be written to, so essentially it can read as well as right. The problem is that ram memory loses its data as soon as the computer is shut down. This is where the computers flash memory or rom memory comes into play.
What is Computer Memory?- Rom Memory
Rom memory are small circuits of memory that are stored on the motherboard itself. Rom memory holds all the data that a computer needs to initiate and to start up. Rom memory is read only memory, so it cannot be changed and can only be read, that is why it generally only holds the firmware that the hardware needs to start. Rom memory only holds information that is not likely to change any time soon.
What is Computer Memory Hard Drive Space
Most people that use the computer, but dont understand how the computer works or what is computer memory. They think that Ram memory and Hard drive space are the same thing. In reality a hard drive is a metal platter that spins inside a metal case. As it spins the head can read and write information. So the hard drive is used to store long term and large files that can be accessed at a future time. Because ram memory cannot store anything, we use the hard drive to store information we need to access on another occasion.
It is a mistake that most people make when they refer to the hard drive as memory. In reality the hard drive is only a storage device.
What is Computer Memory and How Much do we Need?
Now that we have established that the hard drive is not and does not have anything to do with memory it is easier to realize the importance that ram memory has in our computer. That is why when you are choosing a new computer you should buy a computer that has as much Ram memory as possible.

VoIP Service - the best way to move forward
Communication as we all know is an integral part of our life; something which we just can not function without. World has started shrinking with people having friends, relatives, business clients, dealers et cetera from worldwide. International calling or long distance calling is a lot expensive with traditional fixed line telephones that we have been using for more than a decade now. With this change has come a definite change in the way people view communication resulting in the need for a cheaper telephony.
Internet is one mode of connecting people. It has brought people from across the globe much closer. Gone are the days when you would use inland letters for expressing your feelings for your beloved or sending important information to a client from overseas. World wide web has brought about a revolution in the field of telecommunication by providing a platform for VoIP telephony.
VoIP service or voice over Internet protocol utilises Internet for call termination unlike fixed line phones or PSTN (public switch telephony network) which transmits calls via optical fiber wires. Few basics of this service are given below.
1. It works on packet switching capabilities and not circuit based thereby it is much more efficient than fixed line telephone network. Packet switching capabilities mean that it helps the voice packets take the route which is least congested. As a result there is no issue of latency or jitters.
2. VoIP call termination service uses a single network for terminating voice, video and data. As a result the resources are better utilised.
3. Since it functions mainly on the Internet which is relatively much cheaper than cables which have to be put across different locations to enable calling, the call tariff is very less. You can end up saving more than half of what you pay right now as your telephony bill!
4. With minimum hardware required by VoIP services, the cost of operations is further reduced.
Switching over to voice over IP is undoubtedly a great idea. However one should always do proper research by reading VoIP service reviews for instance, before selecting any particular VoIP service provider to ensure consistent and hassle-free service.

Document Imaging and Processing Typically Go Together
Document Image Processing can be for different purposes.
For example, the processing might be nothing more than cleaning up the document. Typical documents often contain punch holes, black borders, undesired lines, and so on. There are document-cleaning tools that can remove these from the document images after they are scanned. Document cleaning software can also allow users to specify what to do about such elements in scanned images.
Other kinds of cleaning up include:
These and other cleaning tools can be automated by specifying minimum and/or maximum sizes of the elements to be removed.
Major Image Processing Tasks
In the case of text documents, document imaging produces images that humans can read, but machines can't. For making these documents searchable by using the typed words, the text characters on the images need to be converted into a machine-readable format.
This conversion is done using technologies such as OCR (Optical Character Recognition) and ICR (Intelligent Character Recognition). Even hand-printed characters can be recognized to some extent by these technologies.
This kind of conversion is also needed for the purpose of making the document images editable.
Once the images of text documents have been made machine-readable, the next, typical document imaging process is to index them. Indexing makes the documents searchable. Full-text indexing makes them searchable by any word in the document.
Full-text indexing takes up lots of storage space and an alternative is to index by tags and meta descriptions. Tags are words that typify the document's content. Descriptions give short summaries of the content.
The processing of the document images can go even further. Based on programmed specifications, the documents can be categorized and stored in appropriate repositories.
In short, document image processing can facilitate content management by converting paper documents into categorized content ready to be queried by users, all in a matter of minutes with minimal human intervention.
There are mailroom processors that can extract documents from envelopes and then go on to process the documents as above. With this kind of a facility, a single operator can manage mail volumes formerly handled by many clerks, and also go significantly further in the content-management process than the clerks.
Conclusion
Document imaging and processing typically go together. The processing can be simple tasks like removing undesired elements such as distortions and black borders or complex tasks such as converting text images into machine-readable characters and indexing the content.
For example, the processing might be nothing more than cleaning up the document. Typical documents often contain punch holes, black borders, undesired lines, and so on. There are document-cleaning tools that can remove these from the document images after they are scanned. Document cleaning software can also allow users to specify what to do about such elements in scanned images.
Other kinds of cleaning up include:
- Straightening askew images
- Removing borders that exceed given noise-tolerance specifications
- Smoothing nicks and bumps distorting scanned text characters
- Converting white text on black to black text on white
These and other cleaning tools can be automated by specifying minimum and/or maximum sizes of the elements to be removed.

Full-text indexing takes up lots of storage space and an alternative is to index by tags and meta descriptions. Tags are words that typify the document's content. Descriptions give short summaries of the content.
The processing of the document images can go even further. Based on programmed specifications, the documents can be categorized and stored in appropriate repositories.
In short, document image processing can facilitate content management by converting paper documents into categorized content ready to be queried by users, all in a matter of minutes with minimal human intervention.
There are mailroom processors that can extract documents from envelopes and then go on to process the documents as above. With this kind of a facility, a single operator can manage mail volumes formerly handled by many clerks, and also go significantly further in the content-management process than the clerks.
Conclusion
Document imaging and processing typically go together. The processing can be simple tasks like removing undesired elements such as distortions and black borders or complex tasks such as converting text images into machine-readable characters and indexing the content.
How Automotive GPS Systems Work
In recent times driving has become all the more simpler and exciting with the use of navigation systems such as automotive GPS systems. The time where you worried about getting to your intended destination is long gone because the automotive GPS system ensures that you get to your destination in due course without roaming about aimlessly and straying from your intended course. Honda was the first vehicle company to create the automotive navigation system as far back as the early 1980s, at that time a device known as an accelerometer was used in order to determine precise locations as the means to use GPS systems werent available. Nowadays you have a lot of popular vendors selling automotive GPS systems as well as other navigation systems and you are free to make an independent choice.
For those who have no detailed understanding of how automotive GPS systems work, they should understand that these systems make use of satellite signals in order to determine the precise location of a vehicle. Not all automotive navigation systems make use of GPS technology and certain differences exist with other GPS systems that use data on your precise position to superimpose it on a map and determine your particular location.
Different aspects make up a complete navigation system. These different components are the aerial view of the map which changes according to the motion of the vehicle; this component is easily the most crucial component, distance gauge, distance numbers as well as the next curves birds eye view in order to protect you from harm.
Navigation systems make use of road databases which contain a complete listing of the names and addresses of different locations which are stored as geographical coordinates. Any information that requires updating is supplied through internet technology as the vehicles moves from one particular location to the other. It also has a vector map of a particular area which ensures that it is easy to find a person or business if you have their particular name or address.
Databases which are employed in such systems can be easily kept on storage media such as hard disks or by using certain memory known as read only memory. Read only memory comes directly programmed from a factory or stored on other optical storage media devices such as CDs and DVDs. Base maps are usually stored constantly in the memory of the device because they dont change. The base maps are used to provide precise and accurate information about any current location that a user may find themselves in or which they may be interested in. Systems exist which allow for a combination of all these elements.
History has it that the navigation system that was primarily created to function with GPS was developed by Pioneer in the year 1990. Nowadays GPS navigation systems have come a very long way. You can use them not only to determine your location but to locate other essential services such as gas stations, restaurants and motels. Auxiliary functions which include messaging capabilities and the ability to watch DVDs may also come included.

CD And DVD Duplication: An Untreated Threat
We are still used to the process of CD or DVD duplicating which a time is taking process and if we need more CDs or DVDs to burn, then its a nightmare. This problem can be solved by the best use of the processes of CD/DVD duplicators that are available in the market. This is a growing market with the increase of services. Especially for our small companies if there is a need to make copies of any software or any material to send to our clients, or to distribute to our employees then the valuable resources of time and human resource are wasted.
The CDs/DVDs duplication machines save a lot of time by duplicating more number of CDs and DVDs with automatic machines that use robotic arms, which reduces the manual process.
CD/DVD duplication is a method of generating CDs and CD-ROMs by writing empty CD-R discs in a CD-R drive on a PC or by using a CD duplicator. We can also define the CDs/DVDs duplication as, the replica of the optical media through a process of copying. In general we refer it as creating discs to limited extent, which is a contradictory concept to the large-scale process of replication. The content that is required to copy is usually, duplicated to existing record able CDs or DVDs media.
CD Duplication is typical process, where the lesser amount of CDs and DVDs are manufactured at present. The information contained in the CD-R or DVD-R is thus, loaded into the burners. And, your all information is extracted from the source in digital form, generally the CD-R, CD-RW, DVD+R, and DVD+RW will transfer in to the empty discs. The information that is transferred is thus typically verified moreover the disc will then accepted / rejected.
Also, with the increase of advance technology and reasonable price in information technology, many companies are offering similar level of CDs and DVDs duplication services.
The process of CD/DVD duplication is done in two methods. One process is a manual process and another one is automatic. The manual process is used for those who require less CDs or DVDs to duplicate. The automatic process is used by those who need more number of CD/DVD duplicates to be done in a much faster way.
No wonder, with the DVD duplicators we can make the second copy of CDs within 3 to 4 minutes. The automatic CD/DVD duplicators use robotic arms to transfer blank discs from one spindle to another, which facilitates the work instead of manual transferring. By using suction picker or mechanical picker the CDs or DVDs are transferred from one spindle to another. This is a better method of duplicating CDs and DVDs in bulk.
There are many companies that offer cheap services of CD/DVD duplicating process. Most of the services are available on the Internet and the orders can be given online. We can compare the products, their features and the prices to choose the best CD/DVD duplicating machines. Depending on the use and requirements the best machine should be selected or can hire the services if it is not needed.

Cisco Certified Internetwork Expert (CCIE)
The Cisco Certified Internetwork Expert (CCIE) is the highest level of professional certification that Cisco provides. CCIE was the first Cisco Certified qualification, and as such there were no other certifications that could be taken prior. The development of the associate and professional certifications was due to recognition of the fact that a CCIE is over kill for many networking personnel, and also for the vast majority of businesses who employ such people, and that certifications needed to be offered at lower levels. Despite the development of the lower certifications, Cisco has chosen not to make them formal requirements for the CCIE certification.
The CCIE what CISCO describes as its "premium networking certification" is widely regarded as having one of the toughest, most demanding exams. It includes both a written exam and a day-long lab exam. This certification is aimed at senior level networking professionals who design, build, implement, maintain, or troubleshoot complex enterprise networking infrastructures. CCIE recipients can specialize in routing and switching, communications and services, security, or voice systems and technologies. CCIE Routing & Switching Routing and Switching is by far the most popular track, and covers a wide range of subjects, such as: LAN, WAN, Ethernet, TCP/IP, OSPF and BGP,IPv6 and many more. CCIE Security The Security track concentrates on network security and covers subjects such as ASA, IDS, IOS security, security and many others. CCIE Service Provider The Service Provider track focuses on networking in the service provider industry. Subjects include Optical networks, DSL, WAN switching, Voice over IP, Content Networking, Broadband Cable and Metro Ethernet. CCIE Voice The Voice track concentrates on voice solutions for the enterprise and includes subjects such as QoS, MGCP, Call Manager (Cisco's VoIP PABX), Cisco Unity (Cisco's Unified Messaging platform), Unity Express and IP Contact Center Express. CCIE Storage Networking The latest addition to the CCIEcertification tracks is the CCIE Storage Networking track. As the name suggests, the Storage Networking track concentrates on storage networking topics, such as Fiber Channel, iSCSI, FCIP, Intra VSAN Routing and FICON.

Efficient Methods of Diagnosing Strep Throat
The efficiency of existing treatments in curing strep throat strongly depends on the accuracy and speed of diagnosis. In case the diagnosis is inaccurate or established late, the patients are exposed to the risks of receiving the wrong treatment (resulting in increased resistance of the bacterial strains involved in causing strep throat to medications) and of developing serious complications. The treatment of strep throat most often involves the use of antibiotics, medications that play a crucial role in eradicating the causative bacteria and preventing the occurrence of a variety of complications (acute rheumatic fever, kidney disease, coronary disease).
Considering the fact that strep throat (inflammation and infection of the pharynx with Group A hemolytic streptococcus bacteria) sometimes produces symptoms that are very similar to those of sore throat - the viral form of acute pharyngitis (inflammation and infection of the pharynx), doctors may confuse between the two, prescribing the inappropriate treatment and rendering patients more susceptible to developing complications.
In order to accurately separate between viral acute pharyngitis (the common sore throat and strep throat, doctors cant always rely solely on clinical examinations and patients reports of symptoms. In order to find whether the cause of pharyngitis is infection with viruses or bacteria, doctors often choose to perform more conclusive tests. The recommended supportive tests consist of throat culture and the antigen test.
Although the antigen test is quicker to perform, it is also less precise and therefore doctors may perform the throat culture test even when the results of the antigen test are negative. By performing both tests together, doctors can find conclusive data regarding the nature and the exact type of the infectious organism involved in causing acute pharyngitis. However, a good alternative to this combination of tests is the newly introduced optical immunoassay test (OIA), which is very sensitive and quick to perform.
Apart from these microbial tests, the diagnosis guidelines developed by the American College of Physicians (ACP) can also help doctors distinguish between cases of sore throat and cases of strep throat. These guidelines link the probability of Group A hemolytic streptococcus pharyngitis to the following clinical findings: tender anterior cervical adenopathy, tonsillar exudates, complete absence of cough and the presence of fever (bacterial infections are often associated with high fever, sweating and chills). These guidelines are considered to be very effective in diagnosing patients with strep throat and can in most cases replace microbial tests such as pharyngeal exudates, antigen tests and optical immunoassay.

Protect Your Family From The Dangers of Smoke and Fire
Many people are hurt, lose their possessions and die because of fire. Although fire can easily be prevented it is one of the leading causes of injury at home in the United States. In some cases where individuals die of fire, it is because they were not aware that their house or the building that they occupy is on fire.
Fire alarm systems warn people of a potential fire. It warns the occupant while they still have time to either put out the fire or evacuate to safety. Most of today's fire alarm systems automatically call or notify the nearest fire department so that the fire will not spread out of control. Fire alarms are either set off manually or by heat detectors or smoke detectors.
Fire alarms are most of the time set to detect levels of heat or smoke which usually is an indication of fire. Many fire detection systems come equipped with flashing and blinking strobe lights for people who are hearing handicapped. Due to modern technology, fire prevention alarms are now incorporated with residential burglar alarm systems for the greatest protection and the best safeguarding of an individual's residence.
Smoke alarms are a component of any well designed fire prevention system, they sense smoke in the atmosphere of the room, closet or hall of a residence or public building and activate an alarm thus warning people nearby of a possible fire. Smoke alarms sense smoke today either by ionization or optical detection. Many smoke alarms also have carbon monoxide sensors that detect high levels of CO gas thereby providing protection from carbon monoxide poisoning.
The optical detector in smoke detectors is a light sensor which uses a beam like laser. These beam sensors then sends a laser like beam to other sensors, if smoke is non-existent, the laser like beam passes through the optical chamber of the light sensor in a straight line. If smoke is present, the laser like beam is scattered by the smoke particles as it enters the light sensor and the scattered light then triggers the alarm of the smoke alarm.
Ionization detectors are much cheaper than light detectors, although these types of smoke detectors are discouraged from being used because of environmental reasons. Ionization detectors work by detecting particles of smoke by a small amount of radioactive "americium-241" (that is why it is discouraged from being used). This radiated material goes through an ionization compartment. This chamber permits the steady flow of current of electrodes, so that when smoke particles enter this chamber it interrupts the flow thus setting the alarm off.
Some fire alarm systems have sprinkler system that will contain or put out the fire before it becomes uncontrollable. However the only way to prevent fire is to take steps to be careful and take additional preventive measures.

Aviator Sunglasses
Aviator sunglasses are characterized by their oval shaped lenses that narrow towards the bridge of the nose. Aviators are one of the oldest designs of sunglasses and still the most commonly preferred all over the world. When it comes to sunglasses, aviators are considered classics.
Aviator sunglasses were designed in 1936 for military use. The seemingly humble pair of aviator sunglasses was, in fact, useful gear for the armies in the Second World War. Since then, they have evolved greatly and contemporary aviator sunglasses are trendier and sleeker, with additional features like photo-chromatic lenses and gradient lenses.
Aviators are androgynous, meaning that both men and women can wear them. They are usually preferred in black and brown tinged lenses, but green, blue, gray, and violet lenses are also quite popular. They also come in a variety of frames, with gold plated frames being the most favored. The frame of these glasses is very lightweight and thin so as not to add to the overall weight. Plastic frames are less expensive but do not look as dynamic. Aviator sunglasses may have one or two bridges over the nose to connect the two oval lenses.
Lenses of aviator sunglasses can be made of polycarbonate plastic or glass. Plastic reduces the weight of the lens, but glass is more scratch-resistant. The lenses not only block most of the sunrays from entering and harming the cornea, but they also block out harmful ultraviolet radiation.
Though the primary objective of the aviator sunglasses was something altogether different, today they are used mostly as a fashion accessory. Pop stars and movie stars throughout the ages have popularized aviator sunglasses. They are ideal for blocking out the sun on beaches, golf courses, and summer picnics. A good pair of aviator sunglasses does not create any optical distortion and provide healthy protection for eyes from intensely bright sunlight.
Aviator sunglasses generally cost upwards from $50 and the cost may go up to $100 or more depending on the brand manufacturing them. Ray-Ban, Oakley, Dior, and all other popular brands have their own designs of aviator sunglasses.

All about USB Flash Drives
Out of all the components in a computer, one of the most important is the data storage device. With more and more data being generated, there is an increasing demand for better data storage devices.
Data storage technology has improved in leaps and bounds over the last decade. Firstly, there has been a dramatic increase in the capacity of storage devices such as DVD, CD and even Floppy disks. Secondly, numerous new storage devices have been introduced, some of them completely solid state (no moving parts) like CD, DVD, flash drives, zip drives and memory cards. Thirdly, the technology has moved from a mere magnetic storage to optical and magneto-optical drives.
Even the hard disk which traditionally meant a stationary or fixed storage device is becoming removable. The storage devices are coming in many forms: traditional discs of varying sizes from 5 to even 0.3, key chain devices (flash drives) and stamp size memory cards.
They are no longer used with PCs alone but also with cameras, mobile handsets, PDAs, MP3 devices, Auto PCs and GPS devices.
The information stored is not just programmes or data. It includes songs, movie clippings, video clippings, photographs or maps. Also, with medical imaging equipment going digital, very soon the content could be ultrasound, X- ray, MRI or CT scan images.
The personal storage technology has improved out of the need to provide faster, larger and better storage facility. There are four goals leading this phenomenal growth. First is to push the limits of packaging density so that one can store more data in less space. Second tries to make them more reliable with long life. The third goal is to consume less and less electrical power and the fourth, of course, is to make the devices more affordable.
Data storage memory is primarily of two types. The primary memory is the volatile memory and is erasable. The secondary memory is non-volatile and is of a more permanent nature. Basically, when talking about the data storage devices, it is generally assumed to be about the secondary memory.
Secondary memory is used to store data permanently in the computer. The secondary storage devices are usually as follows:
Hard Disk Drive: This is the most common type and is used in almost all computers. The others include the floppy disk drive, the CD-ROM, DVD-ROM, and the flash memory (USB data card).
Out of these, the USB flash drive is playing an important role in the market. The high points of a USB flash drive are its size and capacity. It actually behaves like a portable hard drive. It can be used for transferring the data and also for the backup or archiving of small but essential data.
Each USB drive is made up of a case of tough plastic or metal containing a printed circuit board that contains NAND flash memory to store digital data. The entire assembly has a single USB connector which is inserted into a USB port when in use. USB drive offers solid state memory.

The Past And Present Of Computers
Computer (computador) is an appliance which can manipulate data in accordance with a list of instructions. It is a type of data processing system.
Today the computer (computador) has become indispensable in every household and comes in numerous physical forms. The first modern day computer was developed in the mid-20th century, though the concept of computer (computador) and various similar machines existed before. It actually started in 1837, when `The Analytical Engine`, the first fully programmable mechanical computer, was designed by Charles Babbage.
The Earlier versions were huge and bulky and used up a whole room. The device EDSAC (Electronic Delay Storage Automatic Calculator) was one of the very first computers that could implement the stored program architecture. In comparison to them, modern computers (computador) have tiny integrated circuits and are much better in terms of capacity and speed as well as accuracy. Today`s tinier version can even fit in your wrist watch and are powered from the watch battery. Personal computers can be found in almost every house today and in various forms. They are in fact the icons of the information age.
What makes computers (computador) highly versatile and distinguishable from other appliances is that it can be programmed. A calculator can only calculate, just like a washing machine can only wash, but a computer can be programmed to do any kind of job. Software programs are a list of instructions that can be stored and executed by the computer.
A general computer (computador) has four major sections, the arithmetic and logical unit or ALU, the control unit or CU, memory and the interface for input and output devices. These parts of computer are interconnected by busses. The ALU, control unit, registers, and the interface for input and output devices are collectively known as the central processing unit or CPU. The Early CPUs used to be composed of different separate components, however since the 1975; the CPUs are being constructed on a single integrated circuit, the microprocessor.
The ALU is for arithmetic and logical operations of the computer while the control unit is for directing the various parts of a computer (computador). Its job involves reading and interpreting the instructions of the programs one by one and converting them into control signals for operating other parts of the computer.
The earlier version of computer (computador) used Magnetic core memory but today it has been replaced by the semiconductor memory. The main memory of Computer is divided in two parts, RAM or random access memory and ROM or read-only memory. RAM can be written and read anytime through CPU commands. On the other hand, ROM is pre-loaded with software and data that never changes, and it can be only read by the CPU.
I/O is hardware by the means of which a computer(computador) can receive information from the outside world and also sends back results. Common input devices are the keyboard and mouse. While common output devices include monitor and printer. There are some devices that serve as both input and output devices like Hard disk drives, optical disc drives, floppy disk drives etc.

History And Uses Of Optical Microscopes
Optical microscopes use visible light and a system of lenses to magnify small samples that are usually un-seen to the bare eye. The optical microscope is the first, oldest and simples type of microscope (as opposed to the much more advanced electronic microscope). The first optical microscopes were created in the 18th century. Due to it's compact sizes, simplicity and relatively low price, the optical microscope is very popular, and can be found in use in many areas of biology. Optical microscopes mostly magnify objects for up to 1500 times.
The first optical microscopes were structured in a way that is called "the simple microscope". This structure utilizes only one pair of lenses to create a magnified image of the sample. Today, the simple structure is in use only in the magnifying glass, hand lens and the loupe.
The more advances optical microscopes, and the ones that are popular today, are what's called "compound optical microscopes". These microscopes use a system of many lenses, in order to "compound" and multiply the magnification, and therefore maximize it. The two main lens systems in an optical microscope are the objective lens (near the examined object), and the eyepiece lens (up near the eye of the scientist). Modern optical microscopes use multiple lenses both in the objective part as well as the eyepiece part. The old optical microscopes also used a mirror to provide illumination below the object. The modern optical microscopes use a strong lamp to provide constant and strong illumination.
So what are optical microscopes used for now a days? The main uses of compound optical microscopes include:
The examining small pieces of material, or even a smear or a squash preparation. This is due to the fact that the optical microscope uses light to pass beneath the object and enter the lenses. That's why the item is better be half-transparent. In other uses the optical microscope may be used to examine metal samples, in order to study the metal's structure. At low power, microscopes can be used to examine small living animals and plants. At high power, they can be used to examine bacteria.
It is important to note that the vast advancement in medicinal fields and biology in general, is owed to a large extent, to the invention of the optical microscopes. For example, the way the blood flows in our body was not fully understood until the microscope made in possible to examine small blood vessels behavior.

PC To Phone Service a service to look out for
In today's global economy the status of communication has augmented a great deal. Both residentials and business houses are in the look out for a cost effective mode of communication. Calling through standard telephone lines prove to be quiet costly especially when you have to make long distance and international long distance calls.
VoIP or IP telephony has arrived with a big bang and is proving to be the biggest challenger of public switch telephony network. It helps in terminating calls via the Internet instead of relying on optical fiber wires unlike PSTN services.
The first VoIP applications used computers as a terminal which was attached with headphones and speakers in order to access VoIP network (known as PC to PC service). However the quality of service offered by VoIP proved to be the chief reason for its inability to gain popularity. Things have changed drastically with consistent improvements being made in the field of IP telephony.
With the developments being made in this field, you can now make VoIP calls through PC to phone. This service is not just cost efficient but it is also the best way to get the most out of your computer.
The demand of PC to phone service by the residential users is increasing by leaps and bounds. This is the best time to set sail in this service in order to capitalise on the rising demand of internet phone system. If the only that is stopping you from entering into this field is the cost involved then you can thank your stars. Few pro active VoIP providers perhaps anticipating this have started providing VoIP phone service platform.
Benefit Of Internet Phone Service Platform
The platform provider ideally provides a one stop solution to those interested in starting their PC to phone business. From infrastructure to entire hardware equipments everything is owned and managed by the platform provider and hence your investment according in this new business would be minimal.

World War II Foo Fighters
In the 1938 comic strip Smokey Stover, a firefighter was known for his line, "Where there's foo, there's fire." From Smokey, aircraft pilots borrowed the term "foo fire" to describe the various unexplainable phenomenon seen in the skies over Europe and the Pacific theatre during World War II. While Allied pilots initially thought the flying objects were German secret or psychological weapons, after the war it was discovered that sightings were also reported by the enemy, who had assumed the crafts were US-made. To this day, the sightings remain a mystery.
Over the course of the war, fireballs, estimated to be as big as 3wholesale pearlwholesale necklace00 feet and as small as 1 foot in diameter, were reported and thoroughly documented. These apparitions left witnesses awe-inspired, wary, and frightened-although the foo fighters never harmed or attempted to harm anyone. The CIA was commissioned in 1952 to study the reports and concluded that while mysterious, foo fighters were not a considered a threat to national security.
A Foo fighter is an umbrella term that includes flying objects of various shapes and sizes. Wobbling, or vibrating flares were described as glowing globes of intense green, yellow, red, orange, or white lights. One crew even reported observing the phosphorescent spheres going through a sequence of color changes at regular intervals. Other reports describe them as silver or gold metallic, and disk-shaped. They frequently appeared at the wing tips of planes in pairs or alone, although sometimes they were found in larger clusters of fifteen or more. In one report 150 objects were estimated to be arranged in 10-12 lines. Picking up an aircraft, these blobs of fire could reportedly pace a plane at very high speeds through extensive evasive maneuvers for several minutes. One British officer and his crew of sailors tracked an object from the deck of their vessel for over an hour. Although a few baffled pilots attempted to intercept, and even fire upon the globes, their efforts were unsuccessful, and the objects usually zoomed away of their own accord.
Foo fighters were mentioned in the American mass media. Ponderous articles appeared in Time and Newsweek in 1945, contributing to the wave of UFO consciousness building in the US. By 1952 so many civilians were contacting government agencies regarding UFO reports that regular intelligence work was being affected.
While scientists have never been able to explain the phenomenon, many speculations have been advanced as possibilities. Five of the most plausible theories are:
1. The fireballs may be nothing more than St. Elmo's Fire, a reddish brush-like discharge of atmospheric electricity which has often been seen near the tips of church steeples, ships' masts and yardarms. It also appears at a plane's wing tips.
2. They may have been optical illusions, mere after-images of light remaining in pilots' eyes after being dazzled by flak bursts.
3. Occurrences may have been the rare effect of "ball lightning," a glowing, drifting bubble of light typically eight inches in diameter. These generally, though not always, follow regular lightning strikes.
4. Bright ground objects reflected from the curved plastic canopy of an aircraft can be perceived as images above the horizon.
5. Proponents of the extraterrestrial hypothesis (ETH) have suggested that foo fighters are hard evidence of ETs visiting earth.
Foo fighters are certainly some of the best documented reports of UFOs, and photographs and respected testimony abound. Hopefully in time the mystery will be solved, and this comic book name will be replaced by its true name.

8 Ways to Reduce or Even Eliminate Computer Vision Syndrome
Over the past week "Computer Vision Syndrome" has been in the news. The latest story in "The Frederick News-Post" titled "Prolonged computer use can lead to vision problems".
The article states that more than 88 million people who use computers for more than 4 hours per day suffer from computer vision syndrome, that's about a quarter of the total population of the U.S.
The Bureau of Labor and Statistics estimates state the enormous cost for workman's comp, to the economy, and employers: In 2002, employers reported a total of 487,900 lost workdays due to work-related musculoskeletal disorders (MSDs), representing nearly 50% of all lost work days. On top of these productivity costs, employers have paid approximately $20 billion annually in direct worker's compensation costs. Indirect costs, like lower productivity at work, etc. add another $60 billion, for a total of $80 billion dollars.
The articles quotes Dr. Frishman, an optometrist from Frederick, Maryland, that the top of the monitor should be at the same level when you stretch your arms out. That would mean that I had to dig my monitor into my desk. The correct location of the monitor is: top of screen at or just below eye level, not shoulder/arm level.
Here are some tips to reduce or even eliminate most symptoms:
1. Use a TCO'03 compliant monitor. Not only are they more environmentally friendly than other monitors, TCO'03 also requires compliance with ergonomic standards: contrast, resolution, brightness, adjustability, etc. Make sure that the LCD monitor you use has a "Class 1" rated LCD panel built in. If the literature that comes with the monitor doesn't explicitly say "Class 1" it probably is not.
2. The area behind the monitor should be lit, too. If it is all dark around your monitor (or TV for that matter), the eye has to constantly adjust between bright and dark. Use a light colored keyboard.
3. Dark, black keyboards create eye strain for the same reason. Ideally, the area on your desk where the computer is should be in "lighter" colors.
4. If you need reading glasses, they won't work with your computer. The monitor should be about arms length away (25 inches), books and papers only about the length of your forearm (15 inches). Ask your optometrist what he can do for you. Zeiss Optical has special lenses called "Gradal RD"
5. Avoid glare, reflections, etc. from windows, lamps, etc.
6. Look away from the monitor at least every 15 minutes. Look out the window. In Germany for example, regulations require that every computer worker has to be able to look out a window without getting up. The eye is relaxed when you look into the distance but contracted when you look on closer objects.
7. Human attention span is typically between 20 and 45 minutes. Find your attention span, set an alarm and walk away from your desk for a couple of minutes, stretch, go for a little walk and breath deeply. Do not look at literature or anything close.
8. If you use a notebook, the notebook has to be off your desk to bring you monitor to eye level. Get a notebook stand. This will also prolong the life and increase the stability of your notebook, because it runs cooler. Don't forget to remove the battery when it is charged.

第一卷混在社会 第四十一章和你没完
“嘀嘀！”从后面传来两声车鸣，李天没有在意。
“嘀嘀……！”这个时候，一辆白色的宝马高级轿车在李天的身边停的下来。李天转头一看，心理不由苦笑，不是别人，正是许洋。看来今天是躲不过了。
当李天转过头，宝马的车窗拉了下来。
“许总，有什么事情吗？”李天问道。
“上车！”许洋看着李天，面无表情的说道。
“上车？”
“快点！”
听见许洋的话，李天无奈，最后只好上了许洋的车，车子再次缓缓的开动了起来。两人坐在车中，谁也没有跟谁说话。
“不给我一个解释吗？”过了许久，许洋看着前方对李天说道。
“解释？什么解释？”李天也猜不出来许洋到底是为了什么而要解释，所以只好问道。
“为什么要去酒吧做兼职，你很缺钱吗？”许洋面无表情的问道。
“算是吧！”李天回答道，因为他也找不出其他的理由。
“喝几千元红酒，也有缺钱的时候？”许洋继续问道。
“就是因为喝所以才缺钱的！”李天顺着许洋的话说道。
“以后不许再喝酒了！”许洋用命令的语气说道。
“为什么？”李天不解的问道。
“因为……。”说到这里，许洋一愣，也不知道自己该怎么回答。
“因为酒是穿肠毒药，我不想公司里面出现一个浑身带着酒气的酒鬼！”许洋对李天说道：“更何况你晚上到酒吧简直，没有充足休息的时间，第二天到公司后精神一定会有问题，所以你以后也不要去酒吧当那个什么调酒师了！”
“这你可就说错了。适当的饮酒可以促进血液的循环，有力于消化，吃饭时还可以开胃。”李天不同意道，让他不喝，还不如杀了他痛快。
“那是只适当，你觉的你喝酒是适当吗？一下子少说也要两瓶，两瓶多少钱？几千还是过万？”许洋皱着眉头对李天。
“那也没有办法，我也没有其他的爱好了！”李天摊了摊手说道。
“你是我们公司的职员，我不想因为酒而毁掉你的前途。”许洋继续对李天说道。看见李天没有说话，许洋想了想说道：“这样好了，你退一步我也退一步，一天只喝一杯，怎么样？”许洋建议道。
李天听见后还是没有说话，凭什么样让自己听她的，只因为她是公司的老总？下班时间属于个人，也碍不着她什么事。
“你和阿凤是怎么认识的？”许洋看见李天没有说话，继续问道。
“恩？”李天转过头看着许洋，难道她看出了什么？不会吧，自己掩饰的很好呀！、
“就是严凤，你和她是怎么认识的？”许洋问道。
“就是你让我陪酒的那天认识的，你知道的！”李天小心翼翼的解释道。
“就这么简单？那你怎么会去她的酒吧应聘呢？”许洋听见后又问道。
“我也不知道她就是那家酒吧的老板。我只苏茜黄是北京酒最好，美女最多的八个酒吧之一，所以想去试试，顺便看看那里还有什么隐藏的好酒！”李天说道。
“恐怕你不禁是冲着酒最好去的吧？美女最多是不是也是你去那里的主要原因？是不是觉的一个摇来摇去，变换花样的调酒能吸引许多女孩子的注意，是不是会感觉特自豪？”许洋对李天逼问道，显然李天刚才回答她的答应另她不满意。
“我怎么觉的你的话里有刺呀？”李天歪着头看着对方问道。
“有没有刺你心理明白，公司有条例，正式的职工禁止在其他公司或场所兼职，作为一个主管，你难道对这些事情都不知道吗？你不觉的影响公司的形象吗？要是让可户看见你会给我们公司带来多大的影响吗？”许洋转过头看着李天狠很的说道。
“可我现在不是公司正式的职工，时期期为两个月，我现在还在实习期间，这就说明我还有权利做兼职。我的形象怎么了？我自我感觉还不错呀！”李天指了指前面回答道，提示她开车应该目视前方他可不想就这样英年早逝。
“我要求你以后禁止喝酒，禁止到外面兼职，你答不答应？”许洋没有把李天的警告让在眼里，依然紧紧的看着李天。
“为什么？为我一个合适的理由？”李天说道，本来自己也没打算在酒吧干活的，今天只不过是为了应付一下场面而已，没有想到许洋竟然连自己喝不喝酒都要管，李天不禁和她对着干上了。谁怕谁？大不了一起撞车。
“我说，不许喝酒，不许到酒吧做兼职！”许洋看狠狠的看着李天一字一字的说道。
“你不是说一天一杯吗？怎么又不许我喝了？再说喝酒和兼职是我自己的事情，与许总你好象无关？再说，现在是下班时间，你没有权力也没有人赋予你这个权利来管我，我想做什么事情就做什么事情和你好象没有丝毫的关系，你又不是我什么人，即使是，也管不了我！”李天觉的对方的条件停无理的，而且还拿出一副命令的样子，好象谁欠她似的，把自己当女王了。
“滋……！”一个急刹车，车停了下来。
“你疯了，想死别拉着我！”李天被一晃，头正好撞到了车窗上，对着许洋不禁怒道。
“下车！”许洋冲着李天冷冷的说道。
“开什么玩笑，这里是高速！”李天看着许洋说道。
“我让你下车！”许洋再一次对李天说道，眼睛狠狠的瞪着李天。
“要不你再向前面开一点，下了高速我再下？”李天商量的说道。
“我刚才和你商量，你答应我了吗？”许洋看着李天说道。
“你也没和我商量什么呀！”李天说道，刚才哪里是商量，那里语气简直就是命令。
“回答我的话！”许洋声音一大说道。
“没有！”李天也同样干脆的回答道。
“那么我也不同意，下车！”许洋面无表情的看着李天说道。
“下车就下车，有什么了不起！”看见对方的样子，wholesale pearl虽然和年漂亮，但是李天却没有心情欣赏，门一开走了下去。
“你混蛋！”许洋看见李天下车后朝着李天狠很的骂道，然后发动引擎，飞快的离开了。
“哼，有什么了不起，不就是人聪明点，漂亮点，家境好了点吗？有什么了不起的，象你这样的女人北京……还真没有几个！”说到最后，李天的语调降了下来，看着已经消失了的车，李天不由的浑身打了一个哆嗦。虽然快要到夏天了，但是北京的夜晚还是很冷的，更何况这里还是高速路，也不知道这里是哪！李天看着一望无际的高速路想道。
看着过往的车辆，没有办法，只要伸手准备搭便车，可是过了十多分钟，车过去了好几百辆，就是没有一个人停下。
“*，这素质也太低了吧！”李天不由的骂道，最后没有办法，总不能在这里待一个晚上吧，只好沿着一个方向一直走，一边走还一边摇手，希望能有好心人停下来。
半个小时，北京北六环的高速公路上
“许洋，你他妈给我拉到哪里了？这他妈到底是什么地方？”李天望着前面仍然一望无际的高速公路，仰天长喊道。
一个小时，李天走了一个小时的告诉公路，终于看见前面一个指示牌，上面写着‘小汤山’三个字。李天这才知道自己被许洋从朝阳西门一直拉到小汤山，两地光直线距离就有三十多公里，难怪自己见不到头。
“许洋，我跟你没完…….！”wholesale necklace小汤山附近响起一惊天动地的声音。
“嘀嘀……！”这个时候，一辆白色的宝马高级轿车在李天的身边停的下来。李天转头一看，心理不由苦笑，不是别人，正是许洋。看来今天是躲不过了。
当李天转过头，宝马的车窗拉了下来。
“许总，有什么事情吗？”李天问道。
“上车！”许洋看着李天，面无表情的说道。
“上车？”
“快点！”
听见许洋的话，李天无奈，最后只好上了许洋的车，车子再次缓缓的开动了起来。两人坐在车中，谁也没有跟谁说话。
“不给我一个解释吗？”过了许久，许洋看着前方对李天说道。
“解释？什么解释？”李天也猜不出来许洋到底是为了什么而要解释，所以只好问道。
“为什么要去酒吧做兼职，你很缺钱吗？”许洋面无表情的问道。
“算是吧！”李天回答道，因为他也找不出其他的理由。
“喝几千元红酒，也有缺钱的时候？”许洋继续问道。
“就是因为喝所以才缺钱的！”李天顺着许洋的话说道。
“以后不许再喝酒了！”许洋用命令的语气说道。
“为什么？”李天不解的问道。
“因为……。”说到这里，许洋一愣，也不知道自己该怎么回答。
“因为酒是穿肠毒药，我不想公司里面出现一个浑身带着酒气的酒鬼！”许洋对李天说道：“更何况你晚上到酒吧简直，没有充足休息的时间，第二天到公司后精神一定会有问题，所以你以后也不要去酒吧当那个什么调酒师了！”
“这你可就说错了。适当的饮酒可以促进血液的循环，有力于消化，吃饭时还可以开胃。”李天不同意道，让他不喝，还不如杀了他痛快。
“那是只适当，你觉的你喝酒是适当吗？一下子少说也要两瓶，两瓶多少钱？几千还是过万？”许洋皱着眉头对李天。
“那也没有办法，我也没有其他的爱好了！”李天摊了摊手说道。
“你是我们公司的职员，我不想因为酒而毁掉你的前途。”许洋继续对李天说道。看见李天没有说话，许洋想了想说道：“这样好了，你退一步我也退一步，一天只喝一杯，怎么样？”许洋建议道。
李天听见后还是没有说话，凭什么样让自己听她的，只因为她是公司的老总？下班时间属于个人，也碍不着她什么事。
“你和阿凤是怎么认识的？”许洋看见李天没有说话，继续问道。
“恩？”李天转过头看着许洋，难道她看出了什么？不会吧，自己掩饰的很好呀！、
“就是严凤，你和她是怎么认识的？”许洋问道。
“就是你让我陪酒的那天认识的，你知道的！”李天小心翼翼的解释道。
“就这么简单？那你怎么会去她的酒吧应聘呢？”许洋听见后又问道。
“我也不知道她就是那家酒吧的老板。我只苏茜黄是北京酒最好，美女最多的八个酒吧之一，所以想去试试，顺便看看那里还有什么隐藏的好酒！”李天说道。

T1 Internet Connection
T1 carrier is one of the most popular leased line options for digital transmission that offers high speed internet connectivity at 1.544Mbits per second. Is capable of carrying 24 digitized voice channels at the speed of 1.544 megabits per second.
T1 carrier is one of the most popular leased line options for digital transmission that offers high speed internet connectivity at 1.544Mbits per second. A T1 line is comprised of 24 individual channels, each capable of transferring data at 64Kbits per second. With T1 Internet connection, you can have uninterrupted and reliable data transfer within seconds. In normal phone lines, voices are transmitted through copper wires as analog signal and you can transmit data at around 30 kilobits per seconds with your normal modem. A T1 Internet connection, on the other hand, is capable of carrying 24 digitized voice channels at the speed of 1.544 megabits per second. A T1 carrier can carry 192,000 bytes of data per seconds nearly sixty times more data than that of a normal residential modem. T1 Internet connection is capable of providing uninterrupted data transmission which you would not get if you use ordinary modems. If you want to transmit audio or visual data through your residential modem or through your phone service you have high risk of getting jammed since the speed is so slow. With a T1 service, you can eliminate this risk significantly.
Internet service by service providers convert all voice calls as analog rather than in digital format, which not only takes longer time but frustrates customers now that high speed is available. With a T1 line, you not only increase the speed of your data transmission, but also save time for your valuable online work. With the advancement of fiber optics, lesser time is required to convert analog signals to digital format. Fiber optical wires are sometimes used for T1 line to provide maximum speed, although the normal wires are by copper. In case of ordinary modem or residential telephone connection, thin copper wire is used which can rarely carry much load at the time of transmission of data. In T1 Internet connection, broadband internet connection is used which ensures two-way transmission of data at a faster rate than any other method of transmission. Apart from that, hundreds of users can comfortably share T1 connection, which is impossible if you use modems or telephone line or an ISDN line. If you are interested in online songs and movies, then you will find the ordinary modem or residential telephone service can not meet your demands, as these lines take hours to convert any MP3 files or video files to analog format and to transmit them at the desired destination. A DSL or cable may be options but a T1 line, if you can afford it, is the best option. For a business of 20 or more employees, a T1 service is required. By implementing T1 circuit, you can easily transmit digital and video data at the required destination at great speed and at the same time, have a T1 service thats more reliable.

How to photograph jewelry
Photographing jewellery can be tricky, but with a few concepts and budget below US$500 it is possible to achieve near-professional look of the photographs. This guide is intended for absolute beginners. Terminology is simplified, and camera adjustments are discussed with only jewellery in mind.
1. Equipment
1.1 Digital SLR
Biggest spend for near-professional look of jewellery photography is for the digital SLR. This is an absolute must. Second-hand camera will be as good. Camera without many features and without high Mega-Pixel rate will work just as fine. 3 Mega Pixel is more than enough.
Note that what makes the difference is the quality of the optical system, not the number of actual pixels.
Digital SLR will allow you to manually adjust every aspect of the camera. Automatic modes are not appropriate for jewellery.
1.2 Lighting
Avoid using any flashes. Don't use camera's built in flash. Don't buy stand-alone flashes. In fact, don't buy any lighting equipment. Desk lamps 60W-100W will do just fine.
Photo tent will help a lot, but is not mandatory. You get find them for as little as US$20. Terminology varies, so "Photo Tent" will also be called "Light Cube", or "Soft Light Box". Do your searching and find one approx 20" (50cm) in size.
You will need 3 lights. Two matted lights -- soft lights, and one reflector light. Place one matted light left of the area for jewellery, and one to the right. Place reflector light near where the camera is.
Whatever you do, avoid mixing light types. Use only non-fluorescent lights, and isolate your photo 'lab' away from natural light.
1.3 Tripod
To have freedom with many settings that will be a must, we will have to use longer exposures. For longer exposures to achieve maximum sharpness, we'll need a tripod. Our hand shakes too much, when camera runs at exposition 1/2s or 1/5s. Buy a 'tripod' for US$10-$20. You don't need a heavy duty tripod. If your setup will be on a desk, you can chose mini tripod - approx 10" (25cm), and stand tripod on the desk as well, or longer tripod, approx 50" (125cm) and stand it on the floor.
2. Setup
Position the lights as described above. Two desk lamps with soft light (irrelevant if you are using photo tent -- the tent is there to soften the light), and reflector light at the front. I keep the cube open at the front, for easier adjustments and photographs, unless jewellery is highly reflective of the image of me taking photograph.
Uniform background colour is recommended. White background works great. Black background is a little harder to work with. I use one of the white wooden shelves that was sitting in the garrage. Hardware stores will sell these for a few dollars.
Jewellery neck stands look effective only on some pieces, but for most laying on the white surface is the best.
3. Jewelry Arrangement
Spend time arranging jewellery. Clean the jewellery if needed. Polish and remove finger prints. Lay it nicely. For chains, spend time to even out all links and to lay it in a perfect circle. For fashion jewellery this may be a little tricky simply because it's made of various materials and it just doesn't like to sit perfectly on its own. Use blue-tac to fix it where you want it.
4. Taking Photographs
Set your camera to manual. This is where you can adjust all settings yourself. You can leave auto-focus on if you wish, that is about the only setting you can have automatic. Disable camera flash. With static lighting and without using flashes, you can spend time moving the lights until you get perfect setup, before taking shots.
Learn the following 5 camera adjustments: Aperature (f-number), Sensitivity (ISO number), Shutter Speed (Exposure), White Balance, and Focus. These 5 are your bread and butter.
4.1 Aperature
Also known as f-number. This setting widens or narrows the lens, limiting the amount of light that comes into the camera. This directly affects shutter speed, and film sensitivity (since we're using digital camera, film sensitivity is adjustable like anything else).
This setting is responsible for the 'focal lenght'. With high f-number eg f/22 or f/11, when taking jewellery photographs, parts that are close to camera will be focused as well as parts that are further away. With low f-number, eg f/2, only the focused part will be in-focus, and parts of jewellery that are further apart or closer to the camera will become fuzzy. Use this setting as it suits you. You may want to create certain effect, but if you don't, keep this setting to f/11. Overdoing this setting will limit the light coming into the camera, and you'll have to make sacrifices elsewhere to compensate.
4.2 Sensitivity
Also known as ISO number. This used to be film property, and expressed in numbers like ISO200, ISO400, ISO800 etc. The higher the number, more sensitive the film, less light it needs, and thus more expensive. In Digital SLR's this is merely just a setting, but the higher the number, more noise camera will capture. The more light you have, you can go lower with this number. For our limited lighting, ISO800 or ISO1600 will be fine, but try not to use ISO3200 -- it adds visible noise.
4.3 Shutter Speed
Also known as exposure, it is a measure of time camera will be taking the light. When photographing moving objects, you would want this fairly short: 1/200 or or 1/400. However, we're taking static objects, and with the tripod camera is static as well. This gives us flexibility in going as low as 1/30 or 1/10, or even 1/2. Value 1/2 means that camera takes light from the object for half a second. If anything moves during that half a second, photograph will be blurred.
Adjust shutter speed freely until you get desirable effect. In fact, when taking photographs of jewellery against white background, you will want photos over-exposed. Over-exposure should affect only the white background, where small imperfections of white surface will vanish into pure white. If your camera has light meter, it will display a warning that you have too much light, number 2 or 2.5 could be flashing in your viewfinder. This is good :-).
If your background is black, you'll want it under-exposed. This will keep the black background black, remove some imperfections, but leave the jewellery just fine.
4.4 White Balance
With different colours present in every light source, our eyes naturally adjust to what white is. Cameras try to do the same and for general photography are quite good at it. However, for jewellery, you'll want to try all manual pre-sets yourself and chose best result. If everything fails, manually adjust white balance, until it's good. You won't need to keep changing this setting from one jewellery piece to another.
4.5 Focus
Jewellery is static. It's easy to use manual focus, but auto-focus seems to work just as fine. If camera keeps focusing on the incorrect part, just switch to manual, and away you go. For most applications, auto-focus will be fine though.
4.6 Taking photographs
Take enough photographs for each peace. Use camera built-in display as a guide only. Colors and brightness will look slightly different on the computer screen. You can adjust some of it afterwards, but try to take a perfect shot in the first place.
5. Post-Processing
Restrain youself from using too many features of the photo editing software. All you need to do is manually adjust Brightness and Contrast, and perhaps use 'Sharpen' feature. Don't apply any automatic adjustments, as these will get confused with too much white in the photo, or too much black.
Crop to the area you want to keep, save in internet-friendly format (eg 400x300) and you've got a near-professional photograph. Reuse the same photograph for 'zoom-in' crops. You won't be making images larger, instead you'll be cropping from your original, adjusting and saving.
Digital camera with 6 mega pixels or more will preserve enough of the detail for zoom-in's. If not happy, re-take photos of the detail.

Lightweight Television Comparison
In the past, televisions have been heavy and bulky because a regular cathode ray tube (CTR) TV needed the extra room to enable the visible screen and its scanning picture process the room to work. Today we have the convenience of having magnificent color as well as a lightweight television. These lightweight colorful televisions are Plasma, LCD and DLP TV's.
1) How Plasma, LCD and DLP work
Plasma - Florescent light is the sustaining component of a Plasma TV. Florescent is a matter of gas. Launching electrons into the florescent gas causes the electrons to react quickly. The electrons slam into the atoms, it is much like watching a pinball game in action.
In plasma connected to electricity the negative and positive particles are running at each other. While they are running at each other, they are of course bumping into each other. While striking against each other they display an illustrious intensity of ultraviolet light. This is then displayed upon a screen by several layers of glass with contained gas cells and electrode grids.
LCD - Liquid Crystal Diode - Liquid Crystal is one of those amazing things that are in a state of being more than one matter. Liquid Crystal is multi mattered, just as we are. People are solid, liquid and gaseous, yet we are neither. Therefore, it should not be so hard to understand that LCD is multi mattered.
A heat process that by nature transforms liquid crystal into another aspect of itself that is heat changes the Liquid Crystal into a more liquid than solid matter. As a result, anything made of LCD is temperature sensitive. For instance, a computer monitor or thermometers reaction to hot and cold, as people do shiver and swelter. Liquid crystal is used for many things because of its nature when introduced to polymers, such as bulletproof vests and sails for boats.
With the use of electricity, LCD is able to cast a picture by distributing the crystal-clear sequence or design of blocked light molecules. This in turn manipulates light intensity of its pixels that forms upon the colorful screen face.
DLP - Digital Light Processing
Digital light processing uses technology that is based on optical semiconductors. This digital micro mirror device uses tilting mirrors of aluminum, which uses reflected light and a color filter wheel, to create a picture. The mirrors are laid out in a matrix pattern and each mirror equals one pixel. It is like looking at a photo where each piece displays a small square shaped light reflection. The further away you are from the TV screen the more the picture appears to blend together.
The reflected light is directed through a lens and then onto the TV screens producing the images we see.
DLP TV's are not prone to phosphor burn in, nor are they vulnerable to pixilation where the find lines of the pixels separate.
Current DLP TV's are now made slimmer and more lightweight than in the recent past.
DLP technology is used in many ways besides TV screens, which range from business projectors, video walls and home theaters with more experiments in future uses. DLP is also used for commercial entertainment applications and projection systems used for large group viewing.

5 Materials and Technologies That Just Might Eliminate Digital Camera Shutter Delay
Bob pushed the shutter release button andNOTHING HAPPENED. The football passed into his son's hands and the actual photo he took was one of a cheerleader's pom-pom. Bob missed the touchdown too. He resisted an insane urge to slam the camera to the ground and jump on it.
This was his first digital camera, and Bob had just experienced an unpleasant surprise. He had used film cameras all his life, but when his Yashica went into the shop a friend loaned him a digital camera. He naively decided to take some action shots and discovered the most maddening "feature" of digital cameras the shutter delay.
MADDENING AND FRUSTRATING
Articles on this subject have attributed shutter delay to:
1. The camera's focus system
2. The time it takes the camera to digitally process the image
3. Reaction time of the photographer
Numbers one and three are lag times that most people using digital cameras are accustomed to. Most have used a film camera and know it needs a few milliseconds to focus.
The no-brainer solution is to reduce the aperture of the lens to increase depth of field, or aim the camera at the object you wish to be in focus and depress the shutter button half way in order to "tell" the camera what to focus on, then move the camera to center the image and depress it the rest of the way.
As far as human reaction time, well, it hasn't really changed much for users of film cameras, and people experienced in taking action shots usually get what they want.
So let's look at number 2, the time it takes to process the picture.
TIME TO DO THE PROCESSING
Processing the picture (so the camera can be ready for the next one) comes in several steps to move it from the image sensor to flash card storage:
1. Color corrections. The camera has to examine each and every Charge Couple Device (CCD) element on the photo sensor. It adds green, blue, and red to achieve the right color balance. For a 3 mega pixel camera, the processor has to make 9 million calculations.
2. Sharpening. This boosts the contrast by detecting and sharpening edges.
3. Compression. This process converts the 12 to 14 bits of each CCD sensor to 16 bits by "padding" the information and compressing it to 8 bits. This compresses the file size to 9 megabytes.
These steps require a tremendous amount of computational time. No wonder Bob missed his shot!
CATCHING THE ACTION
There are two ways of capturing action:
1. The "consecutive mode". If the camera has this mode, you can take a series of rapid shots moving through the event. This requires a camera with a large buffer" to hold photos for processing.
2. Anticipating shots by depressing and holding down the shutter release prior to the event. This requires an ability to predict the future, something most of us don't possess.
THE FUTURE OF FASTER SHOOTING
Obviously this would all be simplified if micro processing were faster. Even with large buffers, the speed in which data is transmitted to the processor is prohibited by the rate at which data is conveyed from the CCD. Micro processing speed is the next bottleneck.
