Scientists nowdays are doing some amazing research in the field of medical rehabilitation of wounds, and burn wounds in particular. This research is being done using an ink jet printer, something that is commonplace in every household. But do not dust your printers just yet, the inkjet printers being used here have been specifically modified by scientists.

When it comes to the latest information technology news, the area of ​​bio-printing is a relatively new field of research which involves the use of a normal desktop printer which is fitted with cartridges of cells instead of ink that are capable to print out a thin sheet of human tissue instead of paper.

With this new technology, doctors will now be able to print new skin for soldiers or people with burn wounds. The reason why the army is interested in this technology is that burns account for nearly 30% of all injuries on the battlefield. That being said, the technology, which is still in the development phase, will not necessarily be exclusive to the army, but will also be available to the masses. The technology can also be extended to other individuals who put themselves in the line of fire, for instance, the police and firefighters.

The skin is our body's most important line of defense. It is also the largest organ in our body. Our skin also helps us retain water and heat. But most importantly, it helps provide a very important barrier against various infections.

The losing of large amounts of skin causes some major problems, this is where skin printing technology comes in. Burn patients can heal a lot faster if their wounds could be covered with new skin cells. But it's not as easy as it looks. First of all, burn wounds are normally not flat, but jagged. In those areas where the wound is deeper, a different cell type is needed. That's because the cell type at the top is not similar to the cell type at the bottom.

Therefore, printing new skin involves mainly two types of skin cells:

1. The fibroblasts or Dermis: It makes up the deep layer of the skin, which helps produce the matrix that holds the skin cells together.

2. The other is keratinocytes or epidermis: It makes the outer layer of the skin.

According to the latest information technology news , with the help of these modified printers, scientists are now able to take samples of healthy skin cells from patients and grow them in an incubator. Once they have enough, the cells are loaded into specially designed cartridges. Using cameras, the burn wounds of the patient is scanned and a 3D map of the wounded area is created. Then the computer tells the printer where to start printing and which cells to use.

So is it Precise?

As mentioned earlier, cell printing is carried out by taking apart a normal ink jet printer and modifying it. Then human cells are placed inside the cartridges instead of ink. Now this is where things start to get interesting. Whenever a printer wants to drop ink, it sends a signal to one of the resistors in the cartridges, which then heats up the copper wire and causes a bubble to form which is roughly the size of a human cell. That's how scientists are able to get single cell precision with the bio-printer.

The bio-printer is able to drop each type of cell specifically where it's needed, the wound is filled, and with time, the cells go through the natural process and automatically transform into new skin.

Black Laser Toner Cartridges Can Make Your Printed Images Look Just Like a Professional

Owning a laser printer may seem like something that is too far off because they are the more expensive option on the printing market.

Owning a laser printer may seem like something that is too far off because they are the more expensive option on the printing market. But, over the past few years, laser printer prices have gone down, making them more accessible for the common household to own, or even small businesses to own. They are a high quality printer that gives the product a professional look thanks to the laser beam behind the printing process. Because of the laser, you will need special supplies as the laser printer does not work the same way as inkjet printers do.

The laser printer uses a laser beam and projects an image of the page in the printing line-up on to an electrically charged rotating drum covered with some sort of organic photoconductive element (this is found mainly in the more modern printers that are on the market now). Powdered ink (which is also known as the toner) particles are then picked up by an electrostatic charge and placed in the drum's charged areas, which have not been exposed to the laser beam. The drum then prints the image on to paper by direct contact and heat, which fuses the ink to the paper.

So know that you know what a real laser printer does, what is the toner that you will need to use? Remember, because the printer works with lasers, you need a special kind of ink which is laser toner. These come in cartridges and they are full of a fine dry mixture of plastic particles, carbon, and black coloring agents that make the real image on the paper. This is what gets picked up by the electric charge and put in the drum to later be printed on the paper.

Using the correct form of ink for laser printers are important. You must only use the toner cartridges because of the process for the printer. Using a liquid ink will surely ruin your laser printer and cause you expensive problems in the long run. If you need certain colors, they do make color laser toner cartridges. But your most common toner you will use will be black.

Black laser toner cartridges are the most popular as they are professional and you need them for letters, reports, memos, etc. Having a supply of these cartridges can help you in the future as you will need them. They do tend to have a higher price, but that is because they are unique in use and the laser printer can only use them. But do not fear, you can find many online for great prices to help you keep your supply full.

Common Uses for a Printed Circuit Board

There is no questioning the fact that we live in a society that is dependent upon electronics. One of the unsung heroes in the majority of the electronic items that we use is the printed circuit board, also known as a PCB. These handy devices not only make it possible to produce the electronics that we use, it also makes mass production possible and can automate many of the working factors of the electronics that we use for both efficiency and speed (Source: “What is a Printed Circuit Board “, Business Gross). What are printed circuit boards and what are the more common devices that make use of this electronic miracle?

If you were to take apart any electronic item, such as your computer or a cell phone, you would find a thin board on the inside which is made of an insulating material. The surface is covered with metal, typically on the top and bottom. In the metal surface, etches are generated automatically which produce a pathway that makes it possible for electricity to travel from one component to another. Those various components are mounted to the surface of the board with solder.

Before we discuss the specific electronics which commonly make use of the printed circuit board, it's important to understand that they can be found in almost any location. Regardless of whether you are talking about your cellular telephone or if you are talking about a kitchen appliance, it is likely that they take advantage of what PCBs make possible. PCBs can be fabricated in order to produce almost any benefit imaginable. That being said, here are some of the most common uses for the printed circuit board.

Computers – Although it is not likely that you have heard about a printed circuit board being inside of a computer, you have probably heard of a motherboard. In actuality, they are one and the same. The motherboard is the heart and soul of the computer, allowing all of its functions to take place seamlessly, quickly and conveniently. There are also other PCBs that are located inside of the computer, such as those that handle specific processes within it. These can include the cards that are separate from the motherboard, such as the sound card, video card, modem and the power supply. PCBs also control the function of the memory of the computer (RAM) and allow it to be accessed as needed.

Cell Phones – It does not matter if you use a smartphone or one that is not quite as up-to-date, it is also going to make use of a printed circuit board. PCBs allows for millions of calculations to take place within the cell phone every second. Not only can it allow you to access data, such as checking your email or text messaging, it also decompresses and compresses the VoiceStream so that you can have a conversation.

As technology continues to move forward, there is no doubt that printed circuit boards will play a large role in the future of the electronic items that we use. They will continue to produce faster, more efficient results and will allow technology to keep up with our ever-growing demands.

The most significant element of the present-day world of communications is fiber optics. An ever-increasing number of networks responsible for data communication depend on fiber optics for their effective and successful operation. Optical cables essentially form a part of wide area networks of buildings and campuses.

The principle on which fiber optics works is light. Fiber cables contain plastic or glass filaments, which depend on light signals for the transfer of data from one point to another. Light has a very appealing feature: it can travel more quickly compared to electric current, which has traditionally been employed in the field of communication. Characteristically, optical fibers are quite fragile and thus get contaminated in many ways: through dust particles, through the presence of oils and buffer gel. So they must remain clean and tested after installation in order to ensure an uninterrupted flow of light.

Compared to the usual copper cables, the expense for the installation of optic cables is a bit greater, requiring especially designed tools of superior quality for the process of installation. Because of their functionality, the demand for these cables is sure to increase in the foreseeable future. It is worth investing in the appropriate equipment of good quality, as that would prove economic in the long run. If you like to have an edge over other competitors in the field of communication, you should be prepared to invest and use superior kits.

Test equipment

You can get a wide range of kits for executing various jobs connected with the fiber optic industry. Here are some of the most frequently needed kits:

  • Fusion Splicing Tool Kit
  • Fiber Optic Testing Tool Kit
  • Optical Cleaning Tool Kit
  • Quick Termination Connector Tool Kit
  • Traditional Epoxy and Polish Connector Termination Tool Kit

You should make a careful assessment of the kit that would meet with your requirements for testing fiber optics, while keeping your budget in mind. It would be good to seek the opinion of professionals in the field of installation, maintenance and the inspection of fiber optic cables. You should also ensure to select a reliable company for making the purchase of the needed equipment. You will surely find the Internet of great help. You may also talk to people already in the same business.

Cleaning tools

The list of tools for the purpose enterprises of:

  • Fiber optics launch cable: It's a cable box, employed for testing fiber cables when using an Optical Time Domain Reflectometer.
  • Fiber microscope: This testing equipment is used to ensure that unmated connectors are free of contamination and the face is properly finished. It must be ensured that the connected devices are clean before coupling.
  • Fiber patch cord: This fiber cable is used for making patch cords from various pieces of equipment such as the receiver, transmitter and terminal box to the cables.

Multimedia studies is an interdisciplinary field of academies nowdays, which focuses on the understanding of technologies and cultural dimensions of linking traditional media sources with the newer versions of the same. Its scopes can be explained better if the term communication is blended with the visual part of it, or through the concept of communication design. This is because if communication refers to the need and practice of interaction with people around us so as to make sense of the world and to position ourselves in the broadsocial socio-cultural reality, designing is a science as well to create a plan or a norm , criteria or a custom, for the construction of an object, system or measurable human interaction in business and in society at large. In the complex digital environment around us today, such designing can be so applicable to all transactions that are possible between an individual and their environment and has become a powerful means of reaching out to the target audience. Also, it is such a learning which seeks to attract, inspire, create desires and motivate people to respond to messages, with the objective of creating an impact for the initiator, which can be either to build a brand, move sales, or for general humanitarian purposes.

Considering communication and designing together is a modern systems-based approach, a mixed discipline between design and information-development, concerned with media intervention such as printed, crafted, electronic media or presentations to communicate with people. Thus, the stream of multimedia studies involve a broad spectrum of visual communication, incorporating editing, typography, illustration, web design, animation, advertising, visual identity design, performing arts, copywriting and professional writing skills applied in the creative industries. Students of this stream learn to create visual messages and how well they could be broadcast to the world in new and meaningful ways. Students learn how to combine communication with art and technology through the disciples involving how to design web pages, video games, animation, motion graphics and more. The various mediums to get a message across are advertising, graphic designing, industrial designing, information architecture, marketing, technical writing and so on, to become illustrators, graphic designers, web designers, advertising artists, animators, video editors or motion graphic artists, Egypt even printmakers and conceptual artists.

In West Bengal the 'Brainware University' is the one of its kind, offering extremely job-oriented full-time undergraduate and postgraduate courses in multimedia studies, and thus leading students of this generation to blend their imaginative thinking and their creative faculty to the technology of the day to meet the growing needs of the mass and media in multiple aspects.

Owning a computer is something that is very necessary these days for any type of business to take place. There are few businesses that are running smoothly without any type of computer system set up. That is because almost everyone runs on the Internet now, and many people rely on email to communicate with other businesses or even people within their business. For many places it is necessary to have a printer or a copier in the office so they can access to all their important documents when you need them. In this instance, having all the proper supplies is important to have your business continue to run smoothly. Not to mention, if you were to run out of a certain supply of something, it could be extremely detrimental to the work flow in the office. So, to avoid this from happening, it is important that you get all the supplies you need to stay running.

One of the most important supplies that you could run out of is ink for your printer. If you have a laser printer that uses a powdered toner, a solid ink printer that uses those solid ink sticks, or the more common inkjet printer which uses the liquid ink cartridges, it would be a disaster to run out of ink in the middle of a printing process. In order to stop this happening, a good business head would stock up on a lot of ink (which your printer uses) so you will not stop the working during the day. Most of the ink is found online at cheaper prices than in store, and they will ship directly to you.

Something else you do not want to run out of or have a problem with is toner for your copier. Next to the printer, your copier is the next most important piece of equipment for getting documents when you need them. If your copier is also a fax machine, it is important to keep that fax roll and that copier toner up to date so your printed pages from that machine come out looking good. If your toner is low, the print on the paper will not read as well as it should. This is something that is also very easy to find and buy online at comparable prices.

Having all the right printing supplies will help you keep your business running without taking too much time out of your day to shop for everything that you need. Shopping online is often the fast solution to getting everything you need and it will all be delivered right to your doorstep. How much easier could your shopping be? Finding things at comparable value is important as well as you do not want to spend a lot of printing supplies. Keeping this in mind, you can go about your year of business with all your new printing supplies.

In this day of advanced technology, we often forget that laptop computers are still as important now as the day they first hit the market. Granted, now they are smaller, more efficient, and a lot more streamlined than before, but, businessmen and women use them all over the world multiple times a day. Keeping a healthy laptop is important because you would not want it to crash during the making of an important presentation. If the worst happens, and your computer can not keep a decent charge in the original battery, it is important to shop around for the cheapest new battery, while maintaining the same quality of the brand of computer.

Laptop computers are handy pieces of equipment when you need a computer to work from while traveling or just at a local cafè. The downside to having a laptop that either runs a long time while not plugged in, or a very old computer is the battery. An average laptop battery has a battery life of anywhere from two to four years. That of course always depends on the brand of the computer and the battery, what type it is, how you use it, and how you charge it. Sometimes, over charging your battery, or only relying on using the computer while plugged into the electricity will cause the battery to not live as long as if you run it without the cord attached. Regardless, unless you want to replace your entire laptop computer, you will need to buy a battery when it gets too old and can not stay charged.

The biggest question you need to consider when shopping for a new laptop battery is what brand of computer do you have, and what type of battery does the computer use. There are a few types of batteries that you find for laptops on the market today. The most common, and the most commonly wanted is the Lithium-ion battery. These are very lightweight and have a better performance than the others. It is also much more environmentally friendly than the others as well. This will be the type of battery you want to look for when you start looking at your options.

When you find the type of laptop battery that you need, start price checking and finding comparable prices to get the best deal. Laptop batteries and other miscellaneous computer supplies are often overlooked when shopping, but they are important for a healthy and long-lasting laptop for your business and personal needs.

MCSE Methodology Study of Transmission Media

Every form of transmission media has unique characteristics which makes it ideal for a particular type of service.

Every form of transmission media has unique characteristics which makes it ideal for a particular type of service. In the study of MCSE, you should be familiar with the types of characteristics which include cost, bandwidth, band usage (baseband or broadband), attenuation and protection from electromagnetic interference.

The following article introduces you to bandwidth and band usage.

Bandwidth

The term bandwidth in computer networking represents the measure of the total capacity of a way to transmit data. As an example, a medium that features a high capacity also has a high bandwidth. On the other hand, a medium that features limited capacity carries a lower bandwidth.

Bandwidths are typically better understood by making use of analogy to water hoses. Provided that a half-inch water hose can hold water flow from a trickle as much as three gallons per minute. In that case, the hose can be said to carry a bandwidth of three gallons per minute. A three-inch fire hose on the other hand, may have a bandwidth that is more than 50 gallons per minute.

Data transmission rates often are expressed in terms of the bits which can be transferred per second. A good Ethernet LAN ideally should be able to transmit 10 million bits per second and then has a bandwidth of 10 megabits per second (Mbps).

The bandwidth that a single cable can handle is measured in part by the cable's length. Shorter cable usually can support higher bandwidth compared to a longer cable, which happens to be one reason every cable design indicate maximum lengths for cable operations. In excess of those parameters, the highest-frequency signals would degrade, and as a consequence errors start to appear in data signals.

Band Usage (Baseband or Broadband)

The two (2) methods to allocate the capacity of transmission media are with baseband as well as broadband transmissions. Baseband dedicate the entire capacity of the medium to a single communication channel.

Baseband is considered the most frequent mode of operation. The majority of LANs operate in baseband mode, as an example. Baseband signaling can be transported out with both analog as well as digital signals. Even though you might not be aware of it, you have a good amount of experience with broadband transmissions. Take into account, for example, that the cable television coming into your home from an antenna or sometimes a cable service provider is a broadband medium. A number of television signals can distribute the bandwidth of the cable signal because each one signal is modulated making use of a separately allocated frequency. You can make use of the television tuner to select the channel you would like to watch by selecting the frequency. This method of dividing bandwidth into frequency bands is referred to as frequency-division multiplexing (FDM) and additionally works exclusively with analog signals. A second technique, generally known as time-division multiplexing (TDM), handles digital signals.

Laptop Keys and Replacing the Malfunctioning Ones

The benefits of using a laptop are too well known. It makes life a lot easier. However, like any other device, users need to exercise certain precautions while using the laptop to ensure that they will continue to enjoy trouble free services.

The benefits of using a laptop are too well known. It makes life a lot easier. However, like any other device, users need to exercise certain precautions while using the laptop to ensure that they will continue to enjoy trouble free services. It is not unusual to come across people who keep eating snacks or drinking coffee while searching the net on their laptop, or while playing an online game with friends. Such actions can seriously damage your laptop. Most users do not seem to realize that the replacement of laptop keys is not so difficult an affair as they imagine it to be. Although almost all keys are similar, some parts that go to complete a key are different, and once you have identified the relative parts, replacement becomes easy.

First of all you should understand that the keys of most laptops are almost similar, barring the keys for shift, delete, enter, shift keys and space bar. By watching carefully, you'll realize that the design of the keys of many brands is the same, although some do use slightly different designs. However, the components of all keys are the same. All keys composer of hinges, rubber cups and retainer clips. The functioning and mechanism of all these parts are the same.

For example, you may find the working of your Space Bar erratic. You need not panic at the thought of the largest keys behaving in an erratic manner! As already pointed out, the size and shape of these keys may vary, but they contain the same components, playing the same role. That means that a laptop owner can always manage to get replacements. All smaller keys compose of small hinges and clips, where the larger keys, like the Shift, the Enter and the Space Bar keys composer of larger hinges and a number or rubber cups. So, there is no reason to worry if you find your Space Bar is not functioning normally. Irrespective of the size, all laptop keys are replaced in the same manner.

Well, you may even opt to change the keys of your laptop yourself. You should know that some manufacturers do not offer any warranty for their keys. So it will be smart move on your part to learn to replace the keys yourself. You can order the keys through an online store and seek help from an expert that can provide the necessary instructions. If you lack the time or inclining to replace the keys on your own, you can look for a computer technician for doing the need for you. So, the next time any key of your laptop starts behaving in an erratic way, do not panic or keep wondering how to get it repaired, as repairing or replacing broken or malfunctioning laptop keys is not that difficult.

New Mouse of Microsft That Notifies About Incoming Email

The electronic communication systems, such as e-mail programs have notification features. When a user receives an email, the email program produces a notification.

The electronic communication systems, such as e-mail programs have notification features. When a user receives an email, the email program produces a notification. A user is informed by both the visual and audible notifications. For example, whenever we receive an email on Outlook, it does not us by a visual icon that appears on the screen of our computer and by producing an audible sound. You can observe that the similar kinds of notifications are also provided by Facebook or GTalk like chatting softwares.

Many existing notification systems lose their effectiveness if a computer user leaves the area of ​​his or her computer and later returns. When such a situation occurs a user remains completely unaware about the received emails. If there is no reason to engage the computer, the user typically wants to leave the computer untouched unless there is a reason to engage the computer.

The monitor needs to be powered ON to be notified of a receipt of an e-mail or other communication receipt. There may be some situations where users prefer to turn their monitors off when not being actively used and would still like to receive notifications.

Microsoft has found the solution to this problem and they are coming up with a mouse that illuminates itself with incoming emails and other notifications. They filed a patent in January for this new invention. This new mouse from Microsoft will assist a user by illuminating itself while he or she is away from the computer. The mouse is programmed to blink or flash or other change states as a function of the number of messages that has been received since the user left the computer.

This new feature is advantageous for users using communication programs relating to e-mail, voice mail, facsimile, and various conferencing techniques. The mouse will turn on or off, blink or flash, changing colors, and / or varying in intensity in response to the receipt of an e-mail, voice mail, or facsimile message.

The mouse blinks twice in succession when a user has received two messages in his or her absence. The mouse device will change the color of illuminating light according to a software that a user is using. For example, it may only blink in response to the receipt of a request to join a chat room on yahoo, instant messaging on FB, or a call on Skype. However, it may continue illuminate in the case of Outlook and Gmail when an email will arrive on these programs.
