Use of Technology to Save Time

In the era of fast communication, wind-speed work and cut-throat competition, it is imperative that you save both time and money- to increase your efficiency! The use of cutting-edge and revolutionary technology has certainly made our lives easy and interesting. However, sometimes all the beeping and buzzing makes our life hell but with some sound tips (to choose and use technology), we can certainly make our life more productive and easy!

Here are some advices on how to use technology for saving time:
  1. In order to access your computer needs, make sure that you have a computer or a laptop at home! However, just having a computer is not enough, you need to install software's/programs of your requirement and needs. For example, you may install software's for word processing, spreadsheets, presentations, personal information management, accounting and virus protection.
  2. Many people end up storing a lot of clutter inside the computer. Hence, it is necessary that you prepare a certain type of filling system in your PC- giving specific names and titles to every folder (so that you are able to identify your work instantly). Constantly review the files and folders-retain what you need and remove the ones that are no longer required.
  3. Utilize your telephone services to the maximum. Try installing a Caller ID (for screening the calls) and a headset if you need to use your computer while talking. You can also avail of the other phone services like voice mailbox for routing calls to another phone.
  4. You can even consider the installation of cable modem, ISDN line or DSL connections for your phone, fax and computer- they are quite faster and cheaper as compared to the traditional modems.
  5. While present at the office, you may make use of video calls for talking to the employees. Most of the time, it is quite cumbersome to gather everyone at the same place for holding a meeting/conference/seminar etc but with video calls you can talk to anyone present at any location. Online service like Skype, which is free and available in 28 languages, allows you to connect visually with anyone in the world. So, you can make the most use of it!
  6. Heard about Webinar technology? This technology gives you a chance to have one-way communication from an individual person to the audience. It saves both time and money-just like video calling!
Well, above are some of the ways in which you can use technology for saving money and time! So use technology and enjoy a hassle-free life!

What is Thematic Mapping

Thematic Maps serve an important source of GIS information. A thematic map is a map used to convey geographical information such as climate, density of population, land use and other geographical aspects of any city, region, state or country. Thematic maps also known as geographic assays use/utilize base data of places and coastlines as a reference point and then draw out the inferences.

Thematic maps are used not only for showing the distribution of different attributes but they also depict relationship between different attributes also. Similar to dynamic mapping, thematic mapping enables a geographer to update/change mapping elements and view the changes as they happen. Thematic maps are very useful because they provide information about locations, outline the relationships between different attributes and the charts made can be used for navigational purpose as well.

The origin of thematic maps can be traced back to 1686, when Edmond Halley (an English astronomer) published a map known as terrestrial map. This map can be called as the earliest map that came into existence. However, the obvious use of thematic mapping first came out in 1854, when John Snow, a physician from London utilized thematic principles for devising a map for analyzing the spread of cholera in a particular area. Since then, these thematic maps have been used regularly for getting information about a particular area.

While making a map, the cartographer needs to be careful of portraying the data on the map in such a manner that the audience can understand it very carefully. The cartographer needs to examine the location or the physical area and thereafter collect the data sets. Although the general principle remains the same but there are different techniques for mapping a particular area. Choropleth is the most frequently used method for thematic mapping. In case of Proportional symbols the area or the information is represented with the help of point locations.

In Isarithmic method, the maps are used for depicting smooth continuous phenomena such as precipitation etc. In the Dot method, a particular feature or occurrence is used for displaying a spatial pattern. Dasymetric maps make use of areal symbols. However, although boundaries are displayed on dasymetric maps, these geographic units may span multiple theme values. This method is used quite rarely.

So, I hope that you can see the importance of thematic maps pertaining to the information they convey. Thematic maps are an important tool for getting all kinds of information regarding geographical regions.

Liquid Wood

Do you know that the plastic handbag that you use is dangerous for our environment? Do you know that the plastic is non-degradable and can result in the killing of various animals which eat them? So, if you are really concerned about your environment, then I would suggest that you start using "Liquid wood" and support the banning of plastics.

Simply stating, "Liquid Wood" is a bio-degradable plastic which is made up of lignin. It is basically derived from wood-pulp based lignin which can be mixed with hemp, flax or wood fibers and other additives for creating a strong, non-toxic alternative to petroleum-based plastics. Liquid plastic is seen as a major breakthrough in dealing with the hazardous implications of plastics (that are increasingly being used today).

How is Liquid Wood made?

During the manufacture of paper, the cellulose is separated by the wood industry into three main components namely-lignin, cellulose and hemicelluloses. Out of these, lignin is not required for paper making. So, it is mixed with fine natural fibers made of wood, hemp or flax and natural additives such as wax. After mixing and heating under high pressure conditions, a plastic granulate is produced which can be melted and injection-molded. As, you can see, this plastic is surely a better alternative to the petroleum based plastic which relies on the oil reserves of the world that will automatically get depleted one day!

The research on the manufacturing of bio-plastic began in 1990's by Norbert Eisenreich's group at the Fraunhofer Institute of Chemical Technology. This team developed "liquid wood" and trademarked it with the name of Arboform. This plastic further got processed by Tecnaro a German company which molded and produced it in pellet form. As compared to the petroleum-based plastics, when Arboform is used, it does not add to the atmospheric level of Carbon dioxide. Hence, the normal carbon cycle does not get disrupted with the use of this plastic.

Moreover, Arboform has great thermal and mechanical properties, when compared to putting wood and plastic together. It is a biodegradable thermoplastic engineering material of better quality and vigor that is going to replace all the technological demands revolving around the use of unhealthy plastic. Although car parts and other durable items made of bio-plastic exist today but this plastic has not been used till yet for household purpose because of the high contents of sulphur present inside it. However, research is going on and soon we can hope to find the use of this plastic in household items.

"Liquid wood" certainly has a bright future and can be seen as a serious attempt taken by scientists to protect our environment! The use of "liquid wood" certainly promises a better and safer tomorrow.

Use of Pen drive

The transfer of data takes place between two computers through many devices. You can use Floppy drive, Zip drive, CD ROM and so on. The use of E-mail is also not so new. However with all these devices, I really feel that there are some kinds of problem with each of them. For example if you will think about the CD drive then the space is quiet small, if you will talk about the zip drive then you will find that it is quiet costly.

If you will think about the email for the transfer of large data then you will find that either they take lots of memory space or it takes a long time to transfer. More over you will not be able to transfer the data which is larger than 10 MB.

All these drawbacks really point us towards one thing and that is we really need some solution. If you will not think in detail then you will find that pen drives are really great as far as the transfer of data which is quiet large. The pen drive can transfer data from one computer to another which has USB connectivity.

In fact the pen drives are the solution to almost all the problems. Pen drives can transfer much larger amount of data as compared to the CD drives and the floppy drives. However ever since the DVD drive has been added to the armory I must say that they can also transfer the large amount of data. However they are not rewritable and the CD or the DVD which is rewritable is quiet costly. And if you will talk about the pen drive then you will find that it is quiet cheaper. You just need to buy a good pen drive for once and it will work for a long time if you will handle it with care.

The USB pen drive can transfer the text, audio and the video as well. I really feel that this is too must of the advantages.

Even I cannot really stand without the pen drive. I have gone through various stages when I had to transfer the data which was quiet large from one computer to the other. It is really not possible to carry the hard disk with you and the concept of email too failed because they cannot transfer the data above 10 MB.

Hence I really needed a device which can help me out. And I came across with the pen drive. Now days the pen drive which can store the data which is quiet high as 8 GB are also available. This is really too much of the storage capacity.

What Is Streaming Audio?

Streaming audio is the method to send the audio signals on our computer through the Internet. The main advantage behind it; is that we do not have to completely download the audio files such as .wav files or .au files and wait for them to listen before they get downloaded. But because of Streaming Audio method we can directly hear the audio files as soon as we get them on our PC.

How the process actually happens? Let us discuss it in detail: -

When we click on the link of the song, the entire song starts playing right away. As the audio signal arrives it is buffered for a few seconds and then it begins to play. As the audio is playing, more data is continuously coming and as long as you are receiving a continuous stream of data, you will hear the steady audio.

So as long as there is data in the buffer you will be able to hear the audio sound. But due to congestion on the Internet buffer can go empty and it sometimes becomes very difficult and need to be rebuffered again and again.

Let us talk about its benefits which have made it very useful these days: -
  1. It is treated as the best mode of communication when large audience is watching the live show on the Internet and can even take part in the live discussions and communications with other participants. Thus it helps in increasing the audience over the Internet.
  2. The people who need to listen to particular conference can tune in at their appropriate suitable time and method and thus it helps them in attending the live conference with very little cost.
  3. It is also beneficial to converse with the media, public, employees or other analysts.
Thus it helps in live broadcast as in case of live conference, archived broadcast for those who want to converse at their appropriate time and with their own suitable method and it even helps in indexing by just clicking the links to hear audio files.

Audio Streaming requires software Internet Explorer, Java made web browser, Real player or Window Media Player. Regarding hardware, it needs about 16 MB RAM, 28.8 Kbps to 30 (kilobytes per second) modem, 16 bit of sound card and headphones or speakers.

Streaming audio is nowadays added to the websites to increase the user population over the Internet.
The good quality of Streaming audio can be achieved by first shutting down all the other activities going on your PC and then open up the web browser and media player.

Thus Streaming audio is all about listening to the audio files as soon as we get them from the Internet and do not have to wait for the complete file to get download.

How Hybrid Cars Work

Hybrid car is a combination of electric car and gasoline car. A fuel driven car has a fuel tank and engine and transmission. This tank supplies the fuel to the engine turns the transmission which thus drives the car. The electric car runs on the battery. Battery supplies the electricity to the motor or the engine working on the electrical impulse.

The hybrid car is a combination of both the electric and fuel car. It has the fuel tank as well as the battery. The hybrid car has the gasoline engine, fuel tank, battery, generator and electric motor.

How hybrid car works?

The engine is like the gasoline car but in a slightly modified form and smaller in size than that used in pure fuel cars. The fuel tank is smaller than the fuel tank in fuel driven cars. The generator electric power and is used most commonly in the series hybrid cars.

Generator differentiates the hybrid car from fuel driven and battery driven cars. The parts of the hybrid car are light in weight when compared to the fuel driven cars. Hybrid cars use power from both the sources- gasoline and battery.

This combination is used either in parallel or in series. In parallel combination both the fuel and battery are used to turn the transmission. The fuel tank supply fuel and battery supply the electric current to the electric motor.

In series combination, the fuel and battery are used in series. The fuel engine turns the generator which in turn charges the battery. The battery then turns the transmission. The fuel engine turns the generator which turns the internal combustion engine. The fuel is required till the combustion chamber comes to certain temperature. Once a certain temperature is attained, the fuel consumption turns off and the electric motor comes into play.

Advantages of hybrid car

A hybrid car gives several advantages over the other two types. Firstly it uses less fuel. This fuel efficiency gives higher mileage for the same amount of fuel than that consumed in gasoline cars. This is because the engine is smaller in size in hybrid cars. Besides this the cars utilize advanced aerodynamics to reduce the drag which in torn increase the fuel efficiency.

Besides this the hybrid cars are made of light material and tires which are designed such that they give smooth ride. The battery driven car gives less mileage although they are less polluting than the fuel driven cars. Recharging the battery car add to inconvenience.

The gasoline cars on the other hand give higher mileage but pollute the atmosphere due to the high amount of fuel they consume. The hybrid car gives greater mileage, require less refueling and cause lesser pollution.

How Electronic Ink Works

Electronic ink is used for e-books and electronic newspapers. It is a liquid containing numerous microcapsules. Each microcapsule unit is made up of white particles suspended in a vegetable oil like liquid which act as a carrier medium.

When an electric current is applied the particles appear on the surface of the microcapsule and thus the screen appears white. When an electric impulse is applied to the top of microcapsule then white particles appear on the surface and the part of the surface appears white. When an opposite current is applied then the particles float to the bottom of the surface and the screen appear dark. Thus by alternating the current, the surface can be made to appear dark or white.

The electronic ink display is formed by coating a plastic sheet with a film of ink. This is then laminated on a circuitry layer. This layer is controlled by the display driver. The charge pattern applied to the surface controlled, by the display driver; display the text on the surface of the screen.

E- Ink Corporation will manufacture electronic display for digital watches, cell phones, PDA and pagers. The electronic ink has several advantages over the computer display that are in use. Firstly if you read the electronic ink text, it appears more like the print text in newspapers and magazines. It is more comfortable to the eyes than the traditional display on the computer screen.

The electronic ink can be used any where. You can use it on the signboards, on your walls and billboard. The ink also uses less power when compared to liquid crystal display. The power use is about fifty times less when compared to liquid crystal display.

Xerox and E-ink Corporation are into the business of electronic display. Xerox came up with the electronic paper in 1970s. This electronic paper was a form of electronic ink. This is with the technology of microscopic balls. These balls are white on one side and dark on the other side. When the electric current is applied to these balls, they rotate in the electric field and produce the pattern of dark and white depending on the charge applied.

Xerox has developed a rubber sheet with embedded microscopic balls, which work on the same principle. This rubber sheet is used to produce the pages of digital books.

E-ink is extending the technology to create Radio paper, light weight in nature and it will allow you to download of the news and novel stuff just on a click.

I would again repeat that if you want to really safeguard your mail server or anything related to computer then it is quiet sure that you will have to use some very powerful cryptographic techniques. You can not really neglect that hackers have become very powerful. They can really decipher almost everything. If you will talk about the DES then you will also come to know that even this powerful algorithm has been deciphered.

This is really one of the matters which can make any body frightened. You might find your clients question that their bank are not accepting their mail and taking them as spam. You must know that this all happen because of spammers and I do feel that you will have to take the immediate steps.

What Is an Internet Filter?

Internet filter is one of the methods to edit the content so that we do not get what we don't want. We only get that content which we are willing to see. The world of internet is not a small thing. You will definitely find all kind of contents on the internet. There is also some software piracy being carried out. What would you do if you just want the PDF files related to the topic which you have typed? I must say that you will definitely select the advance search of the Google or any other search engine and then use the search engine filter.

However you must also know that there are some inbuilt filters as well. You must know that the terrorist all around the world post the terrorizing videos on the websites like you tube. I do feel that no government would like their citizens to see these videos because it would definitely have an adverse affect on them. This matter comes under the extreme content.

You will also find some family filters as well. Apart from the family filter there are also some filters which stop the matter which tries to attack the moral value of the people or their religion.

Advantages of the internet filter

Following are the advantages of the internet filters
  1. The internet filters are really very useful when we want to filter out the content. This really speeds up the search process because the search engine now knows that what they have to search for. For example if the search engine knows that it has to search for just images then he will not search the text.
  2. It really allows the network administrator to have a check on their employees. They thus make sure that the employees do not have any other options other than to work properly.
  3. It also protects from the virus and spywares which are really a threat to our computers. There are many sites whose only motto is to make sure is to spread the virus so that the entire network gets crash out.
Disadvantages of the internet filters

Apart from the advantages the internet filters do have some disadvantages. They are as follows
  1. You will definitely find many filters which are really not well prepared. You will definitely find them blocking the websites which they should not block generally. Hence this might really create problem because you will not have the access to the data which you eagerly want to access.
  2. It has not properly being implemented.
I must say that the internet filter is really one of the things which can really be very advantageous if it is being implemented properly.

Plasma Cutters

You must know that the plasma is the fourth state of the matter the other three being the solid, liquid and gas. The optimized use of the compressed gas channelized to generate an electric arc and it cuts through the metal sheet.

Industrialization and the allied processes have traversed the good and bad time in equal strides. The demand of the cutting edge technology has really increased in recent times. And one such cutting edge technology is the plasma - arc process. The plasma- arc process is not a new one. The history of the plasma arc goes beyond the time which is as old as the time when we were witnessing the zenith of the Second World War.

It is really well said that the requirements lead to invention and at that time there was a real requirement of the new technology in welding so that the process can be used I joining of the aircraft material. This effort leads to the invention of the method of the welding which used a proactive shield of inert gas. This shield functioned around the electric arc developed and protected the weld from oxidation or the reaction of the oxygen in the atmosphere on the weld.

The technology related to the plasma cutter was taken to the next level in the next two decade. It was soon found that if we restrict the opening through which the gas used to pass then the heat being generated is increased and this was really desirable for the process. It was also found out that the resultant which passed through the opening and in fact the reduction in the size of opening made the compressed gas to move even faster.

The plasma cutter really found the great application in no time. However the process was really very expensive. I do feel that whenever this has happened some new invention has taken place. For example you can take the example of the aluminum and you cannot forget the effort of Clark and it was only because of his effort that the price of the aluminum went on reducing. I do feel that the same thing happens with the plasma cutter technology. The manufacturer found it really very advantageous to burn the ferrous and non- ferrous metals. The plasma cutters which are available today are really very light and I must say that you easily transport them from one place to the other.

The cost of the process has also been reduced to almost nothing. Now this process is quiet affordable and the cost has really been reduced to the normal. These plasma cutters can be mounted on the trucks and we can take it to any site where we like.

What Is Missing in Electric Car Designs?

Electric cars run on a set of batteries and an electric motor. These are the cars which emits less pollutants and help you save the amount that you spend on fuel. Electric cars are the vehicles which are both user friendly as well as environment friendly. But how are they different from their gasoline cousins?

They differ in the way they turn the wheels. The electric cars use the electric energy to run the wheels while the gasoline cars are the one which burn the petrol or diesel to turn the wheels.

When compared to the conventional cars how do they differ in design and which one is better?

No difference as such. Both are similar externally as well as internally. Both the cars types are available in similar designs. Both come in designs which have cozy interiors and beautiful colors. But the electric cars today much like their gasoline counterparts come in great designs which especially focus on interiors. These latest designs enable the electric cars to run around fifty miles or more with a single recharge.

Internally some electric cars may bypass the use of gasoline and engine completely and hence these structures in such cars may be lacking. While some electric vehicles may carry a secondary engine to provide the backup in case the battery expires and need a recharge. These electric cars thus carry a set of lithium ion batteries along with the electric motor which provide the electric power to run the car.

How electric cars are different form the hybrid cars?

Here you should not confuse the electric car designs with those of the hybrid cars. Hybrid cars are the one which use both electric and gasoline powers. They thus have both the gasoline engines and battery set ups which work together to drive the wheels and improve the fuel efficiency. But when it comes to fuel efficiency they still lag behind electric cars. This is because the hybrid cars still use petrol to function.

Summing up the difference

The conventional cars might take you miles every time you refuel them but it is the electric cars which help you to save the money. a gasoline car can drive about two fifty miles with every refuel and the electric cars can carry you for about hundred miles or so with a single recharge. This is the huge difference. But the easy and comfort which the battery driven cars bring is huge. Although the conventional engine is considered more efficient when it comes to the miles which you have to travel but when it comes to being economical it is the electric cars which come to the rescue.

Types of Software

Software is the medium by which a user directs the computer to perform certain task. Software is a collection of programs or procedures designed to perform specific operations. Software can be called as the set of programs, procedures or instructions which are used to operate computer and other related devices. Software in contrast to the hardware is the variable part of your computer. 

Software can broadly be classified into application software and system software. 

 Application software 
 
This is the software that performs all the applications which the user is interested to do. This software directly performs the instructions given by the user. The user can perform one or more specific tasks with the help of application software. Different types of educational software, business software, computer games and automation software used in automation industry are some types of application software. Productivity software such as word processors and spreadsheets, graphic software, CAD and industry specific software are some other types of application software. 

System software 

These are the programs which support the application software. These are the programs which help you to run the hardware and your compute system. Programs such as operating systems, device drivers, servers, utilities are some types of system software. System software provides an application environment to the application programmer and insulates him from the complex computer programs running behind the scene so that he can perform the tasks. 

Some also include programming software in this classification. This is the software which helps the application programmer to device different programs to run specific files or perform specific operations on a computer. The software assists the user to use different programming languages conveniently.  There are integrated development environment which help the user to do so. Besides this interpreter, compiler, debugger and linkers are other set of programming software. 

Different types of software can be purchased from the market where they are available in CDs or DVDs. They are also available as shareware, freeware, public domain software, liteware and as open source. 
Shareware are the software which are available for a limited trial period. This is a type of demonstration software which the user can use for a limited time. Once the time expires the user has to purchase the software for further use. Liteware on the other hand is the software which the user can download to perform certain task. But part of the software remains disabled till you purchase the product. 

Freeware is the software which you can freely download but they come with certain copyright restrictions. Similarly the public domain software is the one which you can download freely from different sites and there are no copyright restrictions attached to them.

Stop Motion Animation

If you have ever seen cartoon show Gumby then you can probably guess what stop motion picture actually is. This is one of the animation techniques widely used these days by the animators. Using this technique a physically manipulated object can be made to move on its own. 

What stop motion animation does is that it saves you from endless repetitions which you have to make by drawing the same figure over and over again to show just one move. A slight variation in drawing can make the movement haphazard and disrupts the theme altogether. Stop motion animation helps you to overcome such boredoms associated so that you can develop your own animation which you can stream on you tube or share with your friends. 

What is required to develop a stop motion picture? 
This is a creative technique. All that you require to make your own stop motion picture is 
  • An idea
  • A character 
  • A theme or a plot 
  • A digital camera 
  • A computer which is capable of running multimedia software. 
  • A software 
  • This is a time consuming technique. Therefore to be a successful stop motion animator you also need some patience. 
  • Besides you also need paper, pencil, or a puppet which you can use as a central character in your theme. You can also use a dry erase board for this. It is more comfortable to use as you don't have to mess with the pencil and eraser work. 
How can you make your own stop motion animation? 
For this the most important thing is a character and a plot. You need a character to present your idea. You can use wire to make your character or puppets which you can directly buy from the market. You can also draw them using paper and pencil. Here you have to use your imagination. A plot makes the animation interesting. A simple yet interesting story keep the viewer glued to screen. Therefore lay down a simple plot which gives your character an importance. 

Make a set up. Place your character in the setup. Develop a background which brings out the character and the theme. Next, place your digital camera in front of the set so that you can start shooting pictures. Make sure that your camera is placed well and supported well. 

Remember that more the photos, smoother will be your video. Also make sure that the source of light is well placed so that you get clear pictures. Move the puppets or figures bit by bit. Continue to take pictures in different positions for every single move. Repeat the motion sequence till required movement of your character is complete. 

Save the pictures on your computer and use the movie software to complete the process and finalize your animation.

Diving Computers

If scuba diving is your hobby then you must be aware how important it is to find out the dept of dive and the time for which you are at that dept. diving computers or dive computers or decompression meter are devices which can help you with this.

What are diving computers?
The diving computers are the devices which are used by the professional scuba divers to find out the time and dept of the dive. This device displays the dept at which you are and the time for which you are at that dept so that you can time yourself deep under water.

How do these diving computers work and what information do these computers provide you?
The diving computers work continuously. They calculate and recalculate the time and the dept on the basis of the partial pressure of the inert gases in your body. These computers measure the surrounding pressure of the gases so as to estimate the partial pressure of the inert gases in the body of the diver. For this the computer uses the decompression algorithm in the diver's tissues to estimate accurately the partial pressure of the gases.

Thus these computers give you the accurate and updated information of the dive time, decompression and the depts. At which you are. This computer also warns you about the excessive ascent rates and the decompression stops that you missed.

The computer also tells you about the oxygen toxicity, the temperature of the water, the pressure of the gas remaining in the diving gas cylinder. All this is of utmost help so that you can plan your time under water.

The modern day diving computers have the LCD screen which display the information related to the depth at which you are under water, dive time, the ascent rate, the decompression stop depth time required, the gas pressure in the diving cylinder and the estimated time for which the remaining gas in the cylinder is available depending on the consumption rate.

Some diving computers also warm the diver about the excessive ascent rate, when the diver exceeds the oxygen toxicity limits and missed decompression stops. Some diving computers also calculate the decompression schedule of other gases other than oxygen.

Which type is best for you?
This depends on the type of diver you are. Decide on the basis of the under water expeditions that you take. if you are a professional them opt for an advanced computer which give you the detailed information but if you are the one who take this as a recreational activity then you can search for more basic devices which can make our diving safe and enjoyable.

But make sure that you do not rely completely on these devices. This is because in the end they are machines and they can also go nonfunctional. So, ensure that you have some other device which can give you a back up while you are deep under water exploring the fauna and flora.

Chromatography

Chromatography is made up of two words chroma which means color and graphein which means to write. Let's explore this wonderful concept used widely to separate different components in a mixture.

What is chromatography?
Chromatography is a process which helps to separate the components of a homogeneous mixture. The process thus helps in the quantification and analysis of the mixture and its components.

Scientists use this method to find out the different components that make up the mixture. This is a physical method which consists of the components distributed in two phases: mobile phase and the stationary phase.

The stationary phase is the mixture which is to be separated into its components and the mobile phase is the liquid which can be a solvent. The components in the mixture separate on the basis of the solubility and their differential affinity to the mobile and the stationary phase.

On the basis of the type of the stationary phase, the mobile phase and the separation mechanism, chromatography can be classified into different types.

Classification of chromatography
  1. On the basis of the stationary phase
  • Planar chromatography: the stationary phase is on a plane support.
  • Column chromatography: the stationary phase is in the form of a column.
2. On the basis of the mobile phase
  • Gas chromatography: when the mobile phase used is the gas.
  • Liquid chromatography: when the mobile phase used is a liquid.
3. On the basis of the separation mechanism

Classification on the basis of the separation mechanism depends on how the components are separated.
Ion exchange chromatography, affinity chromatography, partition chromatography, exclusion chromatography and adsorption chromatography are some types of chromatography based on the separation mechanism.

What are the uses of chromatography technique?
It is used widely in the researches carried out in the field of biotechnology, pharmaceutical industry and manufacturing plants. The environmentalists use it to find out the level of pollutants in the water samples.

The forensic labs use it to detect, quantify, separate and identify the samples which they obtain at the site of crime. The technique is used in the manufacturing plants to purify the samples and the products.

What are the benefits of chromatography technique?
The primary benefit is that the complex mixtures can be separated into their components. Very small amount is required for this purpose. The other benefit is its simplicity. The method is simple and takes less time. The method does not require costly setups and no major expertise is needed to perform the task. It can separate in fact any substance soluble or volatile in nature if the right mix of solvent, absorbent material, fluid carrying the components and operating conditions are used.

192.168.0.1- its Functions and Uses

This is the default IP address which is used by business and home networks. This address establishes a default gateway for the home networks. The IP address came into existence in 1970. The Internet protocol address are non routable. 192.168.0.1
Address is considered as a private address and is used as a default for the routers which are sold under the name of D-link and Netgear. The address is set as default and once you purchase the D-link or Netgear router you can change the address by accessing the network admin console. Other private IP addresses are 10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255 and 192.168.0.0 top 192.168.255.255.

There are two Internet protocol address standards; one is IP version 4 and the other is IP version 6. The IP version 4 is the common one which has four bytes. Each byte (also called as octets) takes the value between zero and 255.

The technology came into existence in 1970. Everything from net browsing to e-mailing depends on the internet protocol address. To make the internet protocol addresses more user friendly and readable they are expressed as dotted decimals.
Each byte in an IP address is called as an octet. Each byte in address is made up of eight bits. Thus each octet in the address range from zero to 255 thus making the full range of IP address from 0.0.0.0 to 255.255.255.255.

How 192.168.0.1 function?
The routers are the devices that transmit the data between the computers in a network. The data is transmitted in the form of packets by the routers. The routers use network address translation to detect the packets in the network and transfer them to the destination computer.

To manage your network and make adjustments you can log on from http//:192.168.0.1 and make the adjustments. Through this you can adjust the firewall, ports, passwords and alter the IP address and chage your user name.

How to use the IP address?
If you are using the D-link or Netgear then refer your user manual. Read the manual and follow the instructions to use your IP address.

To correct the trouble that you have with your router first verify the address on your computer. You can find the address in the properties option of the My Network on your computer. Right click the icon to find the address.

Next go to the LAN connections in the properties option enter the correct address in the internet option. Enter 192.168.0.1 in the default gateway and 255.255.255.255 in the subnet.

If your IP address router is altered then you first look at the address in the default gateway. Then click the start icon and in the 'run' enter the ipconfig and press enter. Then in the factory setting click and hold the button for few minutes, switch off the power and release the button only when the light start blinking in the router.

LCD or Plasma TV's-which one is better

Both the technologies give you the crystal clear colorful pictures. Both of them stand at par when it comes to sound and picture quality. They are similar with flat panel and slim designs.

You can hang them on wall of your living room just like you hang a large framed painting. Everything seems similar between the two. There is some difference though. Both have their pros and cons. So, let's discuss and find out which one is better.

Let's discuss this in the light of picture quality, viewing angle and the functional features that we consider in general and in particular.

Picture quality
This is governed by contrast, uniformity of the picture and blackness level. Compare the two on the basis of contrast and you will find that both deliver high quality crystal clear colorful pictures. But under controlled light conditions, such as for the home theater room plasma TV is a better option. But if your room is bright enough with all sorts of light then for you LCD TV is a better option.

This reason for this lies in the technology. The plasma screens are constructed such that the light finds no route to escape. The cells are tightly packed which prevent the leakage. Thus the black part of the picture which the plasma TV displays is much deeper than that of the LCD TV.

In terms of color accuracy plasma TV scores above LCD TV. The images displayed on plasma TV are richer in color when compared to those displayed on the LCD screen. but the latest LCD TV use LED light and color field sequential technology which help LCD TV to overcome this shortcoming and reach at par to the plasma TV.

In terms of contrast ratio the LCD panels score low. The difference is obvious when the light comes from all the directions. This ratio falls in off axis viewing.

Picture uniformity
The uniformity in brightness through out the screen and the smoothness of picture delivered decides the picture uniformity. More smooth the image and more the uniformity in brightness higher is the picture uniformity. The plasma TV here scores above the LCD televisions.

Viewing angle
You judge the viewing angle of a TV by sitting on either side at a certain distance and view the images on the screen. The television which delivers high quality picture without any deterioration in contrast, color etc from either side is said to have a better viewing angle.
