What is e-Learning

If you could stop time and inexpensively bring together all of the people in your organization who need to learn and the resources to teach them, you would not need e-learning. In the real world, people have jobs to do and budgets are limited. Your learning program will need the power of technology to overcome the limitations of time, distance and resources.
You know that people learn in many different ways and at different times. To support these different learning needs, you will need different e-learning delivery methods. Additionally, you will need a way to develop and manage e-learning. Click on the following e-learning solutions to learn more.Use e-learning to overcome the limitations of time, distance and resources.
We can help you create an e-learning program or improve your existing e-learning program with our e-learning consulting services, e-learning software, e-learning authoring tools andlearning management system (LMS).
No single e-learning method is best for every learning need. You will most likely need to use several e-learning technologies as well as traditional learning methods. A blended learning program combines e-learning and traditional learning methods. Blended learning can provide the convenience, speed and cost effectiveness of e-learning with the personal touch of traditional learning.

How we indian think and what we do?

I woke up after having bed tea today morning and saw the news papers front page article and i was completely surprised to see this
ARE WE LIKE THIS ONLY?
what really are our standards of hygiene?Are we conditioned to accept muck or are we hemmed in by a lack of sanitation infrastructure?As rich nations catch us on the CWG( commonwealth games) back foot,rubbing in our third-worldness,is it our culture or complacence that's to blame?
(actually there was a picture of western style toilet and on the top of commode was footprints of shoes )think what this shows.
Many of my friends also do same i request them please don't live in older age OK.

Method to enhance solar energy found

MIT chemical engineers have found that by using carbon nanotubes (hollow tubes of carbon atoms) solar energy can be concentrated 100 times more than a regular photovoltaic cell.

Such nanotubes could form antennas that capture and focus light energy, potentially allowing much smaller and more powerful solar arrays.

Michael Strano, the Charles and Hilda Roddey Associate Professor of Chemical Engineering and leader of the research team and his students tell that their new carbon nanotube antenna, or “solar funnel” might also be useful for any other application that requires light to be concentrated, such as night-vision goggles or telescopes.

Solar panels generate electricity by converting photons (packets of light energy) into an electric current, reports Nature.

Strano’s nanotube antenna boosts the number of photons that can be captured and transforms the light into energy that can be funneled into a solar cell.

The antenna consists of a fibrous rope about 10 micrometers (millionths of a meter) long and four micrometers thick, containing about 30 million carbon nanotubes. Strano’s team built, for the first time, a fibre made of two layers of nanotubes with different electrical properties - specifically, different bandgaps.

In any material, electrons can exist at different energy levels. When a photon strikes the surface, it excites an electron to a higher energy level, which is specific to the material. The interaction between the energized electron and the hole it leaves behind is called an exciton, and the difference in energy levels between the hole and the electron is known as the bandgap.

The inner layer of the antenna contains nanotubes with a small bandgap, and nanotubes in the outer layer have a higher bandgap. That’s important because excitons like to flow from high to low energy. In this case, that means the excitons in the outer layer flow to the inner layer, where they can exist in a lower (but still excited) energy state.

Therefore, when light energy strikes the material, all of the excitons flow to the centre of the fibre, where they are concentrated. The study has been published in the Sept. 12 online edition of the journal Nature Materials.

WHAT IS RENEWABLE ENERGY SOURCE

Today we all are suffering many problems which is generated by global warming so need to think about it how can we reduce this and what are the way to do so......

Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which arerenewable (naturally replenished). In 2008, about 19% of global final energy consumption came from renewables, with 13% coming from traditional biomass, which is mainly used for heating, and 3.2% from hydroelectricity.[1] New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for another 2.7% and are growing very rapidly.[1] The share of renewables in electricity generation is around 18%, with 15% of global electricity coming from hydroelectricity and 3% from new renewables.[1][2]

Wind power is growing at the rate of 30% annually, with a worldwide installed capacity of 158 gigawatts (GW) in 2009,[3][4] and is widely used in Europe, Asia, and the United States.[5] At the end of 2009, cumulative global photovoltaic (PV) installations surpassed 21 GW[6][7][8] and PV power stations are popular in Germany and Spain.[9] Solar thermal power stations operate in the USA and Spain, and the largest of these is the 354 megawatt (MW) SEGS power plant in the Mojave Desert.[10] The world's largest geothermal power installation is The Geysers in California, with a rated capacity of 750 MW. Brazil has one of the largest renewable energy programs in the world, involving production ofethanol fuel from sugar cane, and ethanol now provides 18% of the country's automotive fuel.[11] Ethanol fuel is also widely available in the USA, the world's largest producer in absolute terms, although not as a percentage of its total motor fuel use.

While many renewable energy projects are large-scale, renewable technologies are also suited to rural and remote areas, where energy is often crucial in human development.[12] Globally, an estimated 3 million households get power from small solar PV systems. Micro-hydrosystems configured into village-scale or county-scale mini-grids serve many areas.[13] More than 30 million rural households get lighting and cooking from biogas made in household-scale digesters. Biomass cookstoves are used by 160 million households.[13]

Climate change concerns, coupled with high oil prices, peak oil, and increasing government support, are driving increasing renewable energy legislation, incentives and commercialization.[14] New government spending, regulation and policies helped the industry weather the 2009 economic crisis better than many other sectors.[15]

GEOTHERMAL ENERGY SOURCE

well lets check this also what is actually geothermal energy and from where it comes here i have collected some information

geothermal energy (from the Greek roots geo, meaning earth, and thermos, meaning heat) is power extracted from heat stored in the earth. This geothermal energy originates from the original formation of the planet, from radioactive decay of minerals, from volcanic activity and from solar energy absorbed at the surface. It has been used for bathing since Paleolithic times and for space heating since ancient Roman times, but is now better known for generating electricity. Worldwide, about 10,715 megawatts (MW) of geothermal power is online in 24 countries. An additional 28 gigawatts of direct geothermal heating capacity is installed for district heating, space heating, spas, industrial processes, desalination and agricultural applications.[1]

Geothermal power is cost effective, reliable, sustainable, and environmentally friendly, but has historically been limited to areas neartectonic plate boundaries. Recent technological advances have dramatically expanded the range and size of viable resources, especially for applications such as home heating, opening a potential for widespread exploitation. Geothermal wells release greenhouse gases trapped deep within the earth, but these emissions are much lower per energy unit than those of fossil fuels. As a result, geothermal power has the potential to help mitigate global warming if widely deployed in place of fossil fuels.

The Earth's geothermal resources are theoretically more than adequate to supply humanity's energy needs, but only a very small fraction may be profitably exploited. Drilling and exploration for deep resources is very expensive.[citation needed] Forecasts for the future of geothermal power depend on assumptions about technology, energy prices, subsidies, and interest rates.

Fourth Property of Electrons? Electric Dipole Moment Would Explain Creation of Universe

ScienceDaily — Electrons are negatively charged elementary particles. They form the shells around atoms and ions. This or something similar is what you will find in text books. Soon, however, this information may have to be supplemented.
The reason is that many physicists believe that electrons have a permanent electric dipole moment. An electric dipole moment is usually created when positive and negative charges are spatially separated. Similar to the north and south poles of a magnet, there are two electric poles. In the case of electrons, the situation is much more complicated because electrons should not actually have any spatial dimension.

Despite this, an entire range of physical theories that go beyond the standard model of elementary particle physics are based upon the existence of dipole moment. These theories in turn would explain how the universe in the form that we know it could have been created in the first place. According to prevailing theories, the big bang some 13.7 billion years ago would have had to have created just as much matter as antimatter. Since both obliterate each other, nothing would have remained. In reality, however, more matter than antimatter was actually created. An electric dipole moment of the electron could explain this imbalance.

Up to now, nobody has successfully proven the existence of this assumed tiny dipole moment. Existing methods are simply not sensitive enough. A small piece of ceramic is set to change this soon.

Dr. Marjana LeÃ…¾aić and Dr. Konstantin Rushchanskii from the Institute of Solid State Physics at Forschungszentrum Jülich and Professor Nicola Spaldin from the University of California in Santa Barbara designed this ceramic, which has very special properties, in a virtual laboratory using the Jülich supercomputer JUROPA. The new europium barium titanate should enable measurements to be 10 times more sensitive than they were in the past. According to the Jülich physicists, "this could be sufficient to find the electric dipole moment of the electron."

As electric moment cannot be directly measured, the physicists are working together with scientists from the American Yale University as well as with Czech research institutions in Prague in order to indirectly prove its existence. The researchers in Yale have developed an experimental setup that uses an extremely sensitive SQUID magnetometer to measure the magnetization of the piece of ceramic in an electric field. Their aim is to demonstrate a change in the magnetization when the electric field is reversed. This would simultaneously be the sought-after evidence that the electric dipole moment exists.

In an electron, an electric dipole can only ever be oriented parallel or anti-parallel to the electron spin. In an electric field, most of the electrons are oriented so that their dipole moment is parallel to the field. Fewer are oriented in the other direction. This should lead to a measurable magnetization. If the electric field is reversed, the dipole moments of the electrons are reversed leading consequently to a simultaneous, measurable change in the magnetization. Without an electric dipole moment, on the other hand, the magnetization would remain unchanged.

"It would have been very difficult to find such a well-suited material by trial and error," said LeÃ…¾aić. This material must have an unusual combination of properties: a high concentration of magnetic ions, magnetic disorder at temperatures below four degrees Kelvin and a reversible electric polarization. "Our colleagues in Yale who came up with the idea of the measurements and conducted them had already tested different materials. However, a new material with all of the necessary properties can be found faster with the use of theoretical analysis and computer simulations."

LeÃ…¾aić, as the head of the young investigators group, her group member Rushchanskii, and her cooperation partner Spaldin virtually synthesized and analysed europium barium titanate on the supercomputer in Jülich. To do so, all they needed was its chemical composition and the basic equations of quantum mechanics. From these, they calculated the interaction between individual atoms and electrons and the local magnetic properties. So it was that they found the optimum ceramic.

Team colleagues in Prague have already synthesized and characterized the material in the laboratory and confirmed the properties calculated in Jülich. Only the sought-after dipole moment of the electron remains undiscovered. "Unwanted effects are still inhibiting the measurements," said a disappointed LeÃ…¾aić. "But we're working intensively on improving the material even further."

WHY I MADE THIS BLOG

hi guys myself shah
well i m a student of electrical and engineering in avit Chennai.
I saw each and every student of my college is using laptop almost of them are using it for entertainment or chatting purpose.somewhat using for study purpose since they don't have proper and sufficient soft material for respected subjects.if you compare to other top institutions where each and every thing depends upon soft materials only.except calculation.....even if u see in India's top 2and 3 institutions there is no need of write any thing on paper.which makes them advanced because they are saving very much time while doing this and they can use this time in to lab work and etc.....
If u feeling that it is tough to get soft copies of hard material so u do not be worry i m standing here to solve your problem.
I m just trying to make things easier i mean if u need any kind of soft material related to you studies you only need to visit my blog and check out which material is suited for you n Ur subject.
and one more thing I'd like to say if you feel that you need different thing other than given topic material.then you just comment what you want or write me mail on given email address below.
