    Voice over Internet protocol (VoIP) technology has become standard in many offices and storefronts. It provides higher bandwidth and better capabilities than traditional phone lines. Faxing has changed because of the introduction of VoIP technology. Traditional fax machines that used modulated sound to transmit data are being replaced by software-based digital systems. Small businesses can benefit in a number of ways by switching to fax over IP technology.

    Reliability

    One of the ways fax over IP can help a small business is by improving the reliability of transmissions. Traditional faxes rely on signal modulation to send and receive data. Inconsistencies in the telephone lines, minor hardware issues and even different fax machines can cause these transmissions to fail or to become corrupted. The fax over IP technology is digital and the data has a very low to non-existent chance of loss. This makes digital faxes far more reliable.

    Lower Costs

    Fax over VoIP will save small businesses money over traditional faxing technologies. VoIP protocols can be sent across any network line. They can also be interpreted by a wide range of technologies from computers to multifunction printers and even mobile devices. This makes it unnecessary to maintain dedicated phone lines. It also decouples faxing from older fax machines that require constant maintenance, paper and toner.

    Environmentally Friendly

    Sending fax over VOIP in a network through a line can be done completely electronically. Small businesses do not need to feed a paper printout of an invoice or report into a machine. Similarly, faxes that have been received do not need to be printed immediately or at all. Sending and receiving faxes can be done through a software interface. Faxes can be sent and received as digital files that are viewed on computer screens or mobile devices. This allows a small business to be more environmentally friendly without having to sacrifice the convenience of faxing.

    Better Access for Employees

    The traditional way of sending faxes involved loading a machine, dialing a number and then waiting for a confirmation. This is time consuming and inefficient especially when multiple people need to send a fax. Fax over IP technology makes it possible for employees to send faxes seamlessly from a desktop or other device. The fax can be added as a network device similar to a printer. Employees can simply send documents to the fax from within different programs.

    Higher Quality Faxes

    A large benefit for modern businesses is higher quality faxes. Fax over IP can encode documents created digitally. There are no scanning or resolution issues. People who receive the fax will see the document exactly as it was created. This can make it easier to send documents that include detailed charts, small graphics or complex illustrations. The individual pixel will not run together and become illegible because of issues with an optical scanner at the last minute.

    Recent discoveries about the role of stem cells in cancer have altered the landscape of cancer research, says Medical News Today. There is, however, a long-running philosophical rift over stem cell research at both the state and federal levels. Some groups would rather focus on adult stem cell research, avoiding the moral and ethical questions about research involving embryos. While ethical debate on human embryonic stem cells will continue, much more is occurring on the rings surrounding this bull’s-eye issue, including research in both drug development and adult stem cells.

    Biologists’ understanding of new sources and uses of adult and nonembryonic stem cells is advancing rapidly. Called “niches” or “crypts,” it seems that almost anyplace one looks in the body (nose, eye, hair follicle, intestine, bone marrow, central nervous system), stem cells are being found. From such basic knowledge, it has been reported that successful animal and human therapy using patient stem cells is already occurring. As more stem cell crypts are discovered, the desire to understand how to manipulate them within the body only becomes more acute.

    At the 2007 Annual Meeting of the American Association for Cancer Research, researchers presented new discoveries about stem cells in leukemia, breast and colon cancer that add to the growing evidence that perhaps cancer is, fundamentally, a stem cell problem.

    Interviewed by Vision Magazine at the Stem Cells World Congress earlier this year in La Jolla, California, veterinarian and CEO of Vet-Stem, Robert Harmon, explained how his company is currently providing stem cell therapies for animals. Injected into an injury or degenerated tissue, the stem cell treatment evokes healing in unprecedented ways. As it has been since its discovery almost 400 years ago, the cell and the “vital force” that makes it the seat of biological life continues to hold attention. It is likely that there will be no end to the moral and ethical questions and investigations. Today’s new age of molecular understanding, genomics, proteomics, gene splicing and bioengineering is barely underway. It is not surprising, then, that the more we know, the more we recognize how little we understand.

    The timeline of discovery has been exponential: from discovery of the DNA double helix in 1953, and the understanding of the genetic code, gene splicing and cell differentiation in the 60s, 70s and 80s, science rapidly jumped up the learning curve to the cloning of whole organisms and the discovery of embryonic stem cells less than a decade ago. The future possibilities for the application of this knowledge seem enormous.

    A greenhouse is basically a structure that has been designed to capture and retain the heat from the sun. It is used to grow plants when the climate does not want to cooperate. Greenhouses can be used in a number of science fair projects and can be used to test concepts from a variety of fields of sciences including engineering, physics, botany and biology.

    Project #1 Capturing Heat Energy

    In this project the students will be designing a greenhouse that captures heat energy from multiple sources. They will be capturing heat energy from the sun and geothermal heat energy from the ground. This project will require the student to learn about heat extraction techniques related to solar energy and geothermal energy.

    Sample hypotheses that can be tested with this project include:
    (1) The thickness of the plastic used for enclosing the greenhouse impacts the amount of heat conservation in the greenhouse;
    (2) The opaqueness of the material used for enclosing the greenhouse impacts the amount of heat conservation in the greenhouse;
    (3) The depth of the insulation on the floor of the greenhouse impacts the amount of geothermal heat conservation in the greenhouse.

    Project #2 Growing Radishes

    In this project the student will build a greenhouse so that they can grow radishes and conduct experiments on the radish plants during times of the year that are not normally conducive to gardening. Radish projects can look at a number of things. For example, students can try to cross pollinate radishes with another root vegetable like carrots, they can attempt to grow radishes in sand or they can try to manipulate the size of the radish by exposing the plant to 20 hours of light per day.

    Project #3 Engineering Greenhouses

    For students that are interested in engineering, greenhouse science fair projects can be developed with an engineering focus. For example, students can try to develop a greenhouse using nothing but materials that are normally thrown out or recycled, such as cans, bottles and plastic containers. Students will not only need to design and build their greenhouse, but they will also need to test the effectiveness their greenhouse has in regards to collecting and conserving heat energy.

    Project #4 Studying Solar Energy Applications

    The final project option will be an application project. Students will be learning about solar energy and how to use this knowledge to harness the suns energy to heat a greenhouse. For this project students will design and build a greenhouse that maximizes the energy delivered by the sun. A good approach for this project is to see if their design can magnify solar energy within the greenhouse to make it effective in cold weather.

    Sensata Technologies earlier demonstrated various approaches regarding auto occupant sensing. The demonstration is also aimed at helping engineers design seat belt alert systems that are more precise in order to offer an improved level of consumer safety and convenience.

    The company, which was previously called the Sensors & Controls business of Texas Instruments, showed its new pride which is called as the piezo electric sensor. It also flaunted the current Monocrystalline Silicon Strain Gauge (MSG) force sensor. The sensors gave engineers a range of design options and they make new seat belt alert systems more dependable and ‘consumer friendly.’ The sensors also showcase an edge that could boost air bag classification systems.

    The new piezo electric sensor is deemed the solution to the traditional weight. The problem occurs when detection systems get confused about differentiating between a person or a heavy object such as a box, bag of groceries, and the like thus creating irritating false seat belt alerts. A piezo electric wire, which is mated to a pad that is easily mounted under the seat cushion to deliver input to an electronic module, senses the frequency response of a human. As such, it can determine the relative position of the passenger.

    “Consumers will use seat belt alerts that accurately determine if a passenger is really in the car. A box or laptop bag won’t annoy them anymore because the system thinks it’s a person,” said Michael Mainvielle, the market segment manager at Sensata Technologies.

    The Sensata piezo sensor is engineered to be conveniently integrated into a variety of seat structures, including A- or B-surface mounting. It also accommodates all seat covering options including ventilated seats. Additionally, a three-position sensor is made available for rear seats. The sensor also is designed to complement the overall performance of the vehicle without compromising safety and ergonomics. Moreover, auto parts like the airbags, seatbelts and Banks power will be complemented well by the said technology.

    Due to the sensor’s ability to correctly measure weight and passenger position, the new technology from the manufacturer is also being considered for use with new Federal Motor Vehicle Safety Standard 208 classification airbag deployment systems. The sensors are expected to provide a single, integrated solution for two significant consumer safety concerns.

    The Monocrystalline Silicon Strain Gauge Pressure (MSG) Occupant Weight Sensor (OWS) that uses a silicon MEMS strain gauge element glass bonded to a stainless steel diaphragm. Four MSG sensors could be conveniently mounted within the seat structure to make accurate weight measures for safe airbag deployment and compliance to the FMVSS208. The sensors are available in a wide variety of designs including an axial or flange rigid sensor, a rigid sensor with a Stress Reduction Component (SRC); or an SRC at flange center style. These options from Sensata Technologies offer designers a plethora of styling and mounting flexibility.

    Science Fair Hypothesis

    Younger students will often participate in science fair by presenting a science experiment that has a predictable result. That is, these age groups will follow instructions and use commonly found materials to demonstrate a fact or interesting tidbit about the nature of biology or chemistry. Older students, however, have advanced beyond simply using experiments that have already been done thousands of times before. At this age they will often be required to develop a science fair hypothesis and take all the necessary steps to prove or disprove that hypothesis. This requirement is designed for the older students because they have developed the learning and thinking abilities required for analysis and application. These higher order thinking skills are used to develop the science fair hypothesis and put that hypothesis to the test.

    A science fair hypothesis can be developed around any topic related to science. One of the most popular science fair hypothesis categories currently being explored by older students is in the environmental arena. Many students are developing their own creative science fair hypothesis in order to address the concerns of environmental issues. While these topics decreased for a while, they are making a strong comeback, as students want to research a science fair hypothesis that will have a positive impact on the health of the planet. Many of these science fair hypotheses are developed by students at the high school level as an attempt to discover solutions to issues such as pollution, clean water, greenhouse gases and other problems we are facing on the environmental front. The current student body of budding young scientists is very motivated and interested in issues on this topic.

    A science fair hypothesis surrounding the need for solutions to our even increasing concern for the health of the planet is one from which we all benefit. While the adult world may view these science fair projects as kid stuff there are others that will seriously consider the findings of these young scientists. Scientists currently working in environmental fields judge many of these science fairs. They are in search of the creative minds of the future generation in hopes of encouraging them to continue their work in testing a science fair hypothesis. What begins in school may just be the solution to our ecological problems on the planet.

    If you bring up forensics in a conversation, those involved will often start thinking of scenes from the television show CSI (Crime Scene Investigation). It’s synonymous with scouring crime scenes for minute clues to help criminal investigators create leads in various cases.

    Because of the misunderstanding that’s developed about criminal investigations and forensics, many don’t realize that there is an acute difference between forensics and forensic science.

    Currently, forensic science gets shortened in most discussions to “forensics.” The word “forensic” actually relates to debates, and comes from the Latin word “forensis” or “of or before the forum.” This concept became most prominent in ancient Rome where both the accused and the accuser involved in a judicial case had to advance their arguments in front of a public forum. This led to the usage of the term “forensics” for both public debate and the presentation of legal evidence.

    This concept of “evidence” is what has caused it to run parallel and merge with forensic science. As the judicial system evolved, so, too, did the evidence that was required in cases. No longer was it a matter of verbal debate; instead other forms of evidence were necessary. The concept, that being “forensic” or “before the forum” still holds true. The only thing that has changed is the type of evidence that’s being presented.

    While some modern dictionaries will actually merge the two and provide similar or identical definitions, they are quite separate by origin and practical application.

    The term forensics refers to public debate which includes the presentation of evidence and rhetoric. Forensic Science is something different. It deals specifically with the gathering, identification, research, and scientific interpretation of evidence to determine such things as who was involved in a crime.

    In addition to confusing the terms forensics and forensic science, people often mistake forensic science for criminalistics. However, it’s important to keep these terms in context too. Forensic science involves any discipline that can be applied to evidence. Criminalistics is just one of the subdivisions of forensic science.

    Some of the disciplines that fall under the umbrella of “forensic science” are:

    -Computer Forensics -Forensic Accounting -Forensic Audio Engineering -Forensic Linguistics -Forensic Pathology -Forensic Psychology -Forensic Engineering -Criminalistics

    Criminalistics itself is the scientific discipline which brings together various natural sciences such as biology and chemistry to the examination, identification, and comparison of certain types of evidence. Criminalists deal with biological evidence including DNA and bodily fluids, trace evidence such as fibers, hair, and soil, and impression evidence such as fingerprints and tire tracks. They also are involved with ballistics, drug analysis, crime scene photography and reconstruction.

    As you can see, the forensic sciences deal specifically with the research and examination of evidence so that such evidence can be admitted to and used within the legal system. Forensics on the other hand should be viewed not as the science behind the evidence, but as the presentation and use of the research once it’s completed.

    These days there is there is a lot buzz about the world going green and preserving the environment. Well, I think that all of you might be reading something or the other about “environment and ecology” in newspaper, magazines or over the internet. So, let me throw light on this topic.

    Environmental Science is the scientific study of the ways in which biological, physical and chemical components of the environment interact and the relations between them. Environmental science and ecology are overlapped but different science disciplines.

    Environmental science and ecology are overlapped but different science disciplines. Ecology is the study of the interactions of living organisms with their environments, including relationship with other organisms. Environmental science is multidisciplinary in nature and provides a broad area of study of environmental systems integrating both biological and physical concepts with an interdisciplinary approach.

    Components of Environmental Science:

    Atmospheric Sciences examine the phenomenology of the Earth’s gaseous outer layer with emphasis upon interrelation to other systems. Atmospheric sciences comprise meteorological studies, greenhouse gas phenomena, and atmospheric dispersion modeling of airborne contaminants, noise pollution, and even light pollution.

    Ecology studies typically analyze the dynamics of biological populations and some aspect of their environment.

    Due to the interdisciplinary nature of environmental science, teams of professionals commonly work together to conduct environmental research or to produce Environmental Impact Statements. Environmental science encompasses issues such as climate change, conservation, biodiversity, water quality, groundwater contamination, soil contamination, and use of natural resources, waste management, sustainable development, disaster reduction, air pollution, and noise pollution.

    Geosciences include environmental geology, environmental soil science, volcanic phenomena and evolution of the Earth’s crust. In some classification systems it can also embrace hydrology including oceanography.

    Well, above is a brief overview about Environmental Science and its’ machinery. Having a sound knowledge about our environment will certainly help us to protect Nature, which is the “Gift of God” to mankind.

    What is it about sport that makes it so attractive to people? Is it the adrenaline rush of competitive and/or dangerous sport? Is it the feel good factor of recreational sport; is it the opportunity of socialising with others, or perhaps all of the above? Whatever the reasons may be, sport is certainly getting more and more popular, especially in the developed world.

    A major factor in the popularity of sport is the role of modern technology. Improvements in modern technology have resulted in better playing conditions and equipment for players as well as greater viewing pleasure for spectators.

    Perhaps the greatest changes have taken place in the designing of sporting facilities – such as modern sports surfaces and improved artificial lighting that offer increased opportunity to play. Modern sports surfaces are low maintenance, therefore low cost, and allow year round use. Professional technical expertise is needed to design and install a modern sports surface. Properties such as its rebound resistance, slip resistance, and shock absorption are measured to ensure that the surface is going to provide optimum playing conditions for that sport, whilst giving players ease of movement and adequate protection from injury. Regular maintenance of sports surfaces, both outdoor and indoor is recommended to ensure safety of players.

    Along with an increased number of players there are also an increased number of viewers all over the globe. With the spread of satellite TV, events in one part of the world can be watched real time, in another. Modern flood lighting has not only allowed greater use of sports facilities at the recreational level, but also made possible higher-level competition fixtures such as day-night cricket matches, night-time football matches etc. Electronic score boards, photo-finish timing devices, slow motion replays and large viewing screens have also added to the viewing pleasure of spectators.

    Modern materials are used in the manufacture of synthetic sports surfaces as well as sports equipment. Third generation synthetic grass is made from polymers and provides a maintenance free all-weather surface for sports. The use of composite materials makes sports equipment such as rackets and protective gear, lighter and more durable, enabling athletes to further improve their performance. Advances in modern technology have also led to improvements in the design of sports equipment such as trainers and sports shoes, starting blocks for use in athletics, pole vaults etc.

    Whilst it is difficult for the average user of sporting equipment to keep up with the latest developments, as a guide in the UK sports equipment and sports facilities and surfaces should comply with British standards. Some governing bodies of individual sports also offer certification to demonstrate compliance with international standards.

    The Master’s Thesis in Computer Science is considered as practice for the PhD thesis. MSC research thesis is too hard to embark on without research. The vital requirement of a Master’s Thesis is that it factually reveals the mastery: that you have fully understood the state of the art in your MSC research thesis and that you are competent of working at that level. This is principally significant when the function to be achieved by the structure is too complex to be explained in code, or maybe the condition-action mappings are unidentified in Masters Thesis.

    Writing a Master Thesis is an important task. Though in some ways, Master’s Thesis appears comparable to many other structures of academic writing like research paper, dissertation and essay.

    The MSC thesis offers the challenge to demonstrate your ability to set up and to carry out a scientific research project in a self-responsible and independent manner. MSC research thesis includes:

    * To provide a sufficient explanation and meaning of your research topic,

    * To build a sound hypothetical structure for direction of the research,

    * To collect data in a systematic and confirmable way,

    * To analyze the data significantly and suitably,

    * To present the results in an understandable manner,

    * To draw sound conclusions based on a thorough discussion of the outcomes, and

    * To show the prospective involvement of your research to the procedure of theoretical modernization of the topi

    Emblematic questions that need to be answered during a Master Thesis:

    * What problem are you solving?

    * Why is this problem imperative?

    * Who else is working on this dilemma, on allied research?

    * What process have you used to solve this problem?

    * Why did you select this process/technique? Is this method superior to other methods?

    * What was the most complicated part of your work?

    * What are the lingering troubles?

    We know this all sounds understandable, but every year there are students who get so marsh down in methodological aspect that by the time they are prepared to defend, they cannot persuasively answer these questions. So, you are preparing to write ain a tentative area of Computer Science. Unless you have written many formal documents prior to, you are in for a revelation; it’s complicated.

    Good writing is necessary in a MSC research thesis. However, good writing cannot recompense for a rareness of ideas or impressions. Quite the differing, a clear appearance always exposes flaws.

    If you simply follow the implications outlined and discussed in this paper, you will be well on your way to fruitfully carrying out the Master Thesis requirements for achievement of a Master’s Degree in Computer Science at any Institute of Technology.

    For somebody who’s a techie, 4G is something you ought to already be familiar with. However, if you’re not one of those who’s fond of electronic gadgets, you should know that there’s more to 4G than meets the eye.

    4G is commonly referred to as beyond 3G, a fourth generation wireless technology equipped with a more comprehensive and secured Internet Protocol. It is well-known to provide users with higher speed and better quality anytime, anywhere. It’s packed with better features compared to its predecessors.

    Contrary to what others may suppose, 4G is not limited to mobile phones alone but also in computers. If you’re someone who’s fond of watching videos online, you’ll find that 4G provides high definition videos regardless of your whereabouts. You can surf the World Wide Web faster using any web-enabled devices you have by connecting them to the 4G modem. You can chat with your friends faster, hear their voices clearer and monitor their cams with no pauses and disruptions. You can also share pictures and videos without too much hassle. In case you’re going out, you can still use your mobile to surf the net with 4G mobile technology.

    So why is 4G highly regarded than 3G or other types of mobile phone network? We are living in a high-tech world where additional technological innovations are discovered almost everyday. 4G happens to be one of the most advanced and recent mobile phone networks in today’s age. It is the network of choice by many since it is very accessible. It also has a very high data rate amounting to 100 Mbps and a very extensive bandwidth capacity which added networks fail to provide.

    There are pitfalls though. The main one is that as a cutting edge technology there is likely to be very few places that actually have a 4G network in position.

    Chances are it is used first in highly urbanized areas before it spreads out to rural areas. To remedy this problem, various companies set 4G hotspot areas where users can go to and use it free of charge. In some cases, there are computers which aren’t applicable with 4G since it’s engineered for Windows.

    Today, almost all kinds of cell phones are suitable for 4G. Nevertheless, many techies believe that smart phones are the best because of their quality digital cameras. Others use T-mobile and iPhones which are likewise 4G compatible devices. Another concern will be the price. You can have these gadgets with or without 4G contract. A device with a 4G contract is cheaper with price starting at 199 to 299 US Dollars while those without a contract can cost you 599 to 699 US Dollars.

    Switching to 4G is a good option you can make especially if you’re someone who’s into the latest technological craze and doesn’t want to be left behind. With so many features it offers, 4G is certain to change the way you look at technology.
