Fluorescent Light

Understanding how fluorescent light tubes work begins with a basic understanding of how light is produced. The basic unit of light is the light photon, which is released by an atom when its electrons become energized. As you may know, electrons are negatively charged particles that orbit around an atom’s positively charged nucleus. Electrons have different levels of energy, and move when energy is gained or lost by the atom. When heat passes energy to an atom, electrons quickly shift to another orbital, and almost instantaneously jump back to their original positions. As the return jump takes place, extra energy can be released in the form of a light photon, thus creating light.
We have all heard that fluorescent bulbs are more efficient than incandescent ones, but why? Fluorescent bulbs utilize a more energy efficient process of producing the light that we see. The main difference between incandescent lighting and fluorescent lighting is in the process of stimulating the atoms. Incandescent light bulbs excite atoms through the introduction of heat, resulting in an excess of unused heat energy. Fluorescent light bulbs, on the other hand, utilize a chemical reaction to excite atoms without the same excess heat energy. Both types of bulbs create ultraviolet light, which is not visible to humans. But only fluorescent bulbs utilize a substance that converts the ultraviolet light to visible light, resulting in less wasted energy.

Windows Vista: Improvements

The new Windows Vista operating system was made to be the most reliable Windows yet. Your will enjoy faster boot times and with the built in diagnostics and repair features you will be able to correct issues on the spot instead of calling a repair technician.

Improvements in Windows Vista are as follows:

1. Faster Boot and Resume: You will notice your system will be able to boot faster because of the way Windows Vista handle the scripts and application loading in the background.

2. New technology in Windows Vista can detect poor performance and tune up your system automatically.

3. Built-in Diagnostics: This nice feature will help find errors on your system and repair the problem for you or in the case of finding eminent disk failure will guide you through a backup process.

4. Increased Reliability: Windows Vista is a step up from XP. It is more reliable at reducing user disruptions and includes features to help manage crashes and computer hang ups.

5. Automatic Recovery: Windows Vista automatically diagnoses and recovers an unbootable system to a usable state with the help of the Startup Repair Tool (SRT) a step-by-step, diagnostics-based trouble-shooter that provides users with a guided recovery experience for no-boot situations.

As with every new operating system Windows Vista is not without its flaws. Most errors and issues out there have a work around. With time Vista will replace XP and users are sure to embrace many of the new Vista features.

DNA Fingerprinting

Incorporating the legal system into using DNA evidence is often referred to as DNA forensic profiling. It is being used more and more to correctly identify the guilty criminal of a crime. It can be said of it to be the most effective way to identify the suspect and victim in any crime scene. By using the DNA print of someone, we can be certain to whether they are guilty of the crime committed or not. A DNA test can be used therefore not only to convict the criminal, but to be sure who the real victim of the crime committed was. Since this technology is relatively new, there are even certain organizations that are dedicated to help people who have previously been convicted of a crime and are now serving their sentences who perhaps, were innocent of the crime committed.

There have been many examples of people being released from prison after a legal DNA test showed that the DNA of the previously convicted criminal does not match that which was found at the crime scene. In many cases, some of these innocent people had already completed over half of their time sentenced in prison. Most of these DNA testing centers also provide other DNA testing services as well. There are a wide range of services that are offered, such things include doing a paternity test, finding out ancestry, finding out if you may have Native American Indian genes, or doing prenatal genetic testing. By finding out your DNA print, there is so much knowledge to be gained and your ancestry can be tracked back many years.

Using Nanotechnology for Enhancing Fuel Ability

As we are facing the uncertainly in supply of crude oil, as well as affluent prices, other fuel source is a happening and hot topic. An interesting option could be ethanol, now made out of plants like corn and sugar cane. Companies and universities are eagerly working to grow this process of making ethanol from many other kinds of plant substance; that might considerably augment the amount of ethanol accessible as fuel. Nanotechnology might be to assist this important effort. Researchers at Michigan State University are trying nanotechnology in a neat trick. They are heritably engineering corn to comprise the required enzyme. The plan is to make the enzyme unmoving until activated by high temperatures. When the cellulous part of the corn, like stalk, is procedures, the high giving out temperatures might set in motion the enzyme and change the cellulous to starch. This would avoid the added cost of creation the enzyme separately.

Researchers at the University of Rochester are as well studying how bacteria select an exacting enzyme, or enzymes, to break at specific kind of plant or other bio mass. They expect to make enzymes, which could change cellulous to ethanol in one step, other than the two steps used by the accessible processes. The advantage of cars that could be filled up with either fuel or ethanol has been verified in Brazil, they use much of its sugar cane crop to make ethanol. Using nanotechnology / genetic engineering to make ethanol from cellulous has the latent to make a serious dent in our use of crude oil. However we do require keeping an eye on some safety issues.

Antivirus Software

Antivirus software is very important for any computer system. Antivirus software protects the computers from various types of malicious programs, viruses and Trojans. If you want to make sure that you’re protected from viruses, you should get some antivirus software. This software can offer peace of mind, even for experienced computer users who would be unlikely to open a simple virus.

Antivirus software works in two ways. Firstly, it has a big ‘dictionary’ of viruses, allowing it to scan files and flag any that are known to be viral. Secondly, the software monitors the system for any suspicious activity. One method involves creating decoy files that are hidden from the user and monitoring them to see if they are altered – if they are, then it was almost certainly a virus.

The two giants of the antivirus industry are McAfee and Norton. They are both commercial software based on yearly subscriptions, and at this point there’s little to choose between them – some people swear by one, but just as many will swear by the other. However, both are quite expensive, especially if you buy them as part of the complete security suite.

If you want a free antivirus program, the best around is widely considered to be AVG (the Free Edition). It’s a small but effective antivirus application, popular firstly for being free and secondly for using hardly any system resources to run. AVG is capable of running very fast, even on older computers.

Buying a Flat Panel Monitor

While buying a flat panel Monitor we often get confused. We always look for the best flat monitors. So, here are some tips that will help you to buy flat panel monitors-

1. Flat panel monitors use interfaces - analog or digital. The most up-to-date models have digital interface but an all-digital configuration costs more. If you are attaining an analog flat panel, you should attach it with a digital interface to your video card with a digital out jack to mainstream the signal.

2. Pixel-refresh response time: In a LCD display, the time required to switch from light to dark objects or vice versa, is referred to as Pixel-refresh response time. If the response time is poor (more than 40ms), you may see ghosting effect, i.e., the image seems to remain longer on the screen than it actually is!

Whereas in a text environment this would hardly matter, in a gaming or media centric environment the effect could be a nuisance. More inexpensive models give more ghosting than their steep alternatives. Also, pixel-refresh response time is not brought up on the monitors. You need to watch thoroughly to judge the performance of each model.

3. Viewing angle: One trouble with a flat panel monitor is its viewing angle. Laptop users must have experienced this problem. Moving away from the monitor in any way causes the display to look black! Different models offer different viewing angles horizontally and vertically.

4. Size: bigger is better, but with flat panel, remember 15-inch screen gives you the experience of a 17-inch CRT monitor. If you can pay for 17-inch flat panel, by all means, go for it, if not, a 15-inch screen should not be a disappointment.

Other things to check when buying a flat panel are guarantees and warranties. A three-year warranty is sufficient. People change the monitor settings in stores and while purchasing; make sure that you examine the piece thoroughly. You now have the basic information; all you need is time to check out the market!

Employee Surveillance

Employee Surveillance is an emerging trend. It is a very powerful method of keeping one's business and employees in proper control. Using spy cameras for secret surveillance is not a surprise anymore. There are many examples, like banks, super markets or parking lots. However, one example of secret surveillance that is employee surveillance is widely debatable. Sure, the company has to protect its equipment or intellectual property. However, employee, as every civilian of a modern society has to have rights to his or her own privacy.

One example is that of Restaurant Business. Restaurants are a savior for those of use who do not have time to have lunch or dinner at home. When we go to a restaurant, we expect everything to be smooth from clean plates to nice service. And of course, we expect to have a tasty meal every time. But can we always be sure that we get exactly what we want? So how can we be sure that we eat a clean and tasty food? Well, secret employee surveillance helps us this time. Maybe no one would ever knew that such things happen, if no spy cameras were installed to monitor employees during their work day. In this case, employee surveillance at least, gives us some hope that such employees will think twice before doing something nasty.

In this case employee surveillance is very important. While there are many people who disagree and claim that monitoring employees infringes employee’s rights. They say that employee has to have privacy at home and at work, feel safe and secure all the time. Well, that might be true. However, employing various surveillance tools to monitor employees will definitely decrease the chance of money fraud or other illegal activity. If you warn your employees about spy cameras, they’ll definitely think twice before doing something illegal.

Largest Frog Ever to Hopped on earth

Scientists have found out what they claim as biggest, baddest, and meanest frogy ever to have hopped on earth. This giant frogy is much larger than the ones that are found in the present world. Scientists announced the discovery in north western Madagascar of a bulky amphibian that lived sixty five million to seventy million years ago and it was so nasty that it may have eaten newborn dinosaurs. This brute was larger than any frog that is living today and may be the biggest frog ever to have existed.

Its name, Beelzebufo ampinga, came from Beelzebub, the Greek for devil, and Bufo-Latin for toad. Ampinga means shield, named for armor like part of its anatomy. This frog was 16 inches long and weighed a 4.5 kilogram. It was powerfully built and possessed a very wide mouth and powerful jaws. With the help of its super jaw and claws it hunts down preys. Scientists claim that it is also possible that Beelzebufo took down lizards and mammals and smaller frogs and even considering its size possibly hatchling dinosaurs. This helps us to imagine that what would be the size of this devil frog. This newly discovered creature will provide us an insight to that period and the creatures that ruled planet earth in those times.

Most Powerful Laser Beam Created

Scientists have created a very powerful laser beam. This new laser beam is known as mother of all laser beams. It can focus power equal to all the sunlight heading earth's way. This laser beam can concentrate power up to twenty billion trillion watts per square centimeter. The laser contains three hundred terawatts of power. This power is equivalent to three hundred times the capacity of the entire US electricity grid. And this huge amount of power is concentrated in a 1.3 micron speck- about one hundredth the diameter of a human hair. But this beam cannot be sustained for a long time. This laser beam lasted for thirty femtoseconds. A femtosecond is a millionth of a billionth of a second.

Such high power beams could help scientists develop better proton and electron beams for radiation treatment of cancer. This laser beam can produce this intense beam once every ten seconds whereas other powerful lasers can take an hour to recharge. This laser beam is produced by putting a moderate amount of energy into a very, very short time. In addition to medical use, intense laser beams like these could help researchers explore new frontiers of life. At even more extreme intensities, laser beams could potentially boil the vacuum, which scientists theorize would generate matter by merely focusing light into space.

Signs of Extra-Terrestrial Life

Planets resembling earth can be found orbiting many suns like stars in our galaxy. This theory increases the prospect of finding extraterrestrial life in the vast universe. To know what form of life can evolve in distant planets, it is very essential to know that whether earth like rocky planets exists in the universe. According to a study it is found that between 20% to 60% of stars similar to our sun have conditions favorable for forming rocky planets like earth. The scientists studied six group of stars- all similar to our sun and sorted by age-with the youngest being ten and thirty million years old and the oldest between a billion and three billion years old. They detected discs of cosmic dust around stars in some of the youngest groups surveyed. The dust is believed to be a by product of rocky debris colliding and merging to form planets. Many of these planets will be icy, and some of them will be rocky. This earth like planets can harbor different forms of life. Scientists also predict that there may be objects the same mass as earth. This study gives us vital signs that life may sprout in distant planets and galaxies.
