10 Tips for a Longer Battery Life on your Phone

You’re out with friends and need to make an important call. A glance at your phone tells you the  battery has one bar left and is ready to give up on you. Sound familiar?
Even if you like to carry a spare external battery pack (which is actually very handy) you may need to manage your battery life more efficiently.

We know Nokia phones have a good reputation for a long battery life, and Nokia phones have some great power saving features – one of our favourites is the built-in charging alert which reminds you to unplug your phone when it’s fully charged – but it’s always worth familiarising yourself with a few extra tips to squeeze out that extra bit of juice! So, without further ado…

1. Power Save
Starting with the most obvious, depending on the model, your phone may have a built-in power-save mode which is always a great battery saver.
2. 3G/Bluetooth/Wi-Fi
Who would buy a smartphone without 3G? Yeah, I didn’t think so. Even so, just because we have 3G, it doesn’t mean that we have to use it all the time. When you’re not using it – turn it off, or alternatively use GPRS. The same goes for Wi-Fi and Bluetooth when not using them.
3. Reduce multi-tasking
Multi-tasking on a smartphone is very useful, but it also drains the battery, especially if you’re running a very active Twitter client! A quick and easy way of minimizing this is by using App Stop, which will instantly close all of your running apps – if you’re interested you can download it for free from the Ovi Store.
4. Reduce the brightness
The brightness of your screen has a huge impact on battery usage. Try turning down the brightness on your screen to save power.
5. Keep things cool
Lithium Poly Ion (or Li-Poly) batteries have allowed for up to 40% more battery capacity than previous batteries of the same size, but while that means more talk-time you need to keep them at the optimum temperature (usually around room temperature) and away from hot places which may drain the battery.
6. Noise Control
If you do have your phone set to ring, then try turning down the volume a few notches, the same goes for message tones.
7.  E-mail addict?
Turning off push email or reducing the frequency of email refreshes will mean less use of data and less use of your battery power!
8. Back to black
Did you know that AMOLED screens use a lot less battery power when displaying black rather than white? So, changing your background colour to black could save valuable minutes of battery!
9. Bad Vibrations
Vibrations aren’t necessarily bad, they’re just not efficient! It’s one of the most power consuming features on a mobile phone, so ask yourself, do you really need it?
10. Battery Life Extender
OK, so we might be cheating here a bit but there is an app you can download from the Ovi Store called Battery Life Extender. It’s free and can extend the stand-by time on your phone by up to 30%. It does this by simply tweaking the settings on your mobile.
We hope you found these useful. There are plenty more tips and tricks to prolonging your battery life, we just need to you to let us know what they are. Share away!

Black Hole Mystery Solved

Black holes are an object of research and mystery for the whole scientific community from decades.. Many researchers are working day and night to explore the mysteries of black holes. In this series, a recent invention by Yale University Astrophysicist revels the fact that, There is a upper limit of the mass of any black hole. This research has been also published in Monthly Notices of the Royal Astronomical Society.

WHAT ARE BLACK HOLES?

As most of you are aware BLACK HOLE is a region of space in which the gravitational field is so powerful that nothing, not even electromagnetic radiation can escape from it. Dur to this black holes can not be seen (as they absorbs light radiations) but can only be experienced by their ultra strong gravitational pull. That's why they are named as BLACK HOLE.. They continue to grow in size by absorbing any matter that comes in range of their gravitational field.

HOW MUCH THEY CAN GROW?

Till now it was not sure that what can be maximum size of a black hole. These black holes are now known to exist throughout the Universe and the largest and most massive are at the centers of the largest galaxies. These "ultra-massive" black holes have reported to have mass about One Billion Times that of our own Sun.




CONCEPT OF UPPER MASS LIMIT

According to the new research by Priyamvada Natarajan, an Associate Professor of Astronomy and Physics at Yale University and a fellow at the Radcliffe Institute for Advanced Study, it has been proved, that even the biggest of these Black Holes can't keep growing forever. Instead, they appear to curb their own growth - once they accumulate about 10 billion times the mass of the Sun.




THEORY BEHIND THIS RESEARCH

Normally Black Holes continue to accumulate mass by absorbing matter from neighboring gas, dust and stars. But according to new research by Priyamvada Natarajan, that it is possible only to a certain limit, irrespective of the position of black hole. The reason behind this is that, "Eventually these Black Holes reach the point when they radiate so much energy as they consume their surroundings that they end up interfering with the very gas supply that feeds them, which may interrupt nearby star formation."

EXPERIMENT BY PRIYAMVADA NATARAJAN

Natarajan used existing Optical and X-ray Data of these Ultra-Massive Black Holes to show that, in order for those various observations to be consistent, the black holes must essentially stop at some point in their evolution. This helped her to prove this fact that these black holes can not grow indefinitely in mass and there is some upper mass limit of black holes.

Google Uses Seawater To Cool One Of Their New Data Centers

Google hasn’t ever been slow when it comes to trying out innovative techniques to make its data centers as energy efficient as possible. A number of thoughts seem to have been ocean-centric, such as its wave-powered data center model. A much less futuristic but just as interesting concept is a seawater-cooled data center. Google plans to test out exactly such a data center commencing this Fall.
Earth2Tech reports that Google will begin utilizing the world’s very first seawater-cooled data center in Finland beginning in the Fall. The data center is encapsulated in an old paper mill, which before now had set up seawater channels used for cooling its manufacturing instruments. Simply because that the data center is still in the testing phase, Google doesn’t yet know the PUE (an effectiveness evaluation system for data centers). The closer to 1, the better for a rating. The industry average is somewhere around 2, though Google has far surpassed that with previous data center projects.
The heat conveying devices are the core of the cooling system, and the seawater sends into the heat transfer system, cools the data center, and thereafter the water itself is cooled marginally before being injected back out to sea. Google desired the water that was injected back out to sea to be comparable in heat level to the water that entered the structure, as to have very little impact as is feasible on the nearby ecosystem.
“It was the right thing to do,” says Kava. Google also carried out extensive thermal modelling to research the tides, plant life, and seasons spanning a 30-year-period of the adjoining shore section, and this information and facts determined where the water should come in and out of the system, moreover to have as small environmental effect as possible.
Increasingly more IT companies are looking at how they can help to make data centers ever more energy-efficient. Microsoft, IBM and Yahoo have all accomplished in depth work in innovating fresh ways to shrink the electricity needed to keep servers installed and operating, from employing shipping containers to forming buildings after chicken coops. Even Facebook has designed the Open Compute project to retain energy efficiency as the top priority for future data centers. Google’s use of seawater may not make it to the top tier of innovation, but it is most certainly breaking ground in technology for a cooling system that may be sensible for shoreside data centers.

Completely New World Record Of 26 Terra Bits Per Second Data Files Transmittal Achieved

With video content utilizing ever more bandwidth, the necessity for faster data transmission rates has never been significantly greater.
At this moment a crew of scientists at Germany’s Karlsruhe Institute of Technology (KIT) are claiming a world record in data transmission with the effective encoding of data files at a rate of 26 terrabits per sec. on a stand alone laser beam and sending it over a length of 50 km (31 miles).
The scientists say this is the largest data volume ever transferred on a laser beam and enables the transferral of 700 DVD’s worth of content in just one second.
With no electronic processing methods readily available for a data rate of 26 terabits per second, the team produced a new opto-electric data resolution approach. This course of action relies on entirely optical calculations to break down the first high data rate into reduced bit rates that can then be processed electrically.
The record-breaking data encoding also utilized the orthogonal frequency division multiplexing (OFDM) scheme established on Fast Fourier Transformation (FFT) mathematical routines that is normally put to use in mobile communications networks including digital TV and audio broadcasts.
Because energy is essential for the laser and a couple of process steps only, the team says the new procedure is not only exceptionally fast, but also very power efficient.
“Our result shows that physical limits are not yet exceeded even at extremely high data rates,” says Professor Jürg Leuthold, who led the KIT experiment. “A few years ago, data rates of 26 terabits per second were deemed utopian even for systems with many lasers and there would not have been any applications. With 26 terabits per second, it would have been possible to transmit up to 400 million telephone calls at the same time. Nobody needed this at that time. Today, the situation is different.”
The most current breakthrough follows on from the earlier high-speed data transmission record set by the KIT scientists in 2010, when they productively exceeded the data rate of 10 terabits (or 10,000 billion bits) per second.
The KIT experiment engaged companies and scientists from all across Europe, including members of the staff of Agilent and Micram Deutschland, Time-Bandwidth Switzerland, Finisar Israel, and the University of Southampton in Great Britain. The experiment is detailed in the journal Nature Photonics.

Hence by this controlling the cars will not face any accident and everybody will reach up to his destination safely. To facilitate other drivers, it is manage that anyone could come in convey at any moment and may depart himself at any time. This computer control cars convey is tested successfully by the Volvo in Sweden and the project is funded by the European commission, with an amount of six million Euros.
Food freshening plastic
Even the food which kept in the refrigerators decay after a particular period, but a  professor in Sweden introduce a plastic sheet, when wrapped around the food, it protect the food from decaying. The plastic indicates you the decaying by changing its color. But researcher in Germany has improved it by   producing a new kind of plastic sheet, when rapped around the food will keep it fresh for a long time.
The plastic sheet is treated by a layer of chemicals, when wrapped around the food it comes in contact with the food and starts releasing the antibiotics which defend against the bacteria. It saves the food like meat, fish and cheese for a long time.
Unbreakable glass
Astonishing news came from California that a glass has been produced which is unbreakable and stronger than steel. This glass may bend, but cannot break. The Unbreakable property of glass has been produced by an element Palladium. After testing, it is proved that the substances which have been produced in the past to avoid breaking, cannot match with this glass. Due to this fantastic quality this glass will be used for industrial products, as well as for defense.

The kite will conceive its power by wind. The launch and retrieval of the kite will be carried out by a built-in mechanical system comprising a winch-equipped telescoping tower installed on the bow of the ship. It will save 35 percent of fuel.
Robot skin
A sensitive artificial skin has been introduced that may be coated on the humanoid robot which will make him so much sensitive that it could feel the weight of a butterfly and ant. This flexible skin is developed by a Stanford scientist named Zhenan Bao. This skin is highly elastic and is molded on top of tiny pyramids, which will transmit the pressure applied on it to sensors kept in another rubber layer under. The number of pyramids can be increased according to the sensitivity. These pyramids are placed between two parallel electrodes, so it will detect the pressure on the skin. It is powered by solar cells. Due to this modification it can detect the dangerous chemicals such as explosives or diagnose medical conditions by simply touching a patient.
Magical refrigerator
These refrigerators are working strangely without power. Due to breakdown in power, accurse innumerable problems for storage of food and sensitive medicine, so a new refrigerator has now introduced by a company named True Energy. This new refrigerator can keep the temperature at below 10 degrees Centigrade for up to 10 days without external power! It uses a special device that stores the energy and releases it when required.
New computer device
A Japan based company, Fujitsu has now introduce a wireless monitor, which will give you release of the burden of mess of wires and will connect the computer with monitor. The monitor will through induction. The induction system is simple and uses very little power to transmit signals wirelessly through the air.

Top Inventions In Need

Electrical Fire Extinguisher
The scientists know very well that electricity can extinguish fire, but they don’t the science behind it. Now George Whitesides and his helping hands are working on this theory that the soot particles of the flame can be charged which destabilize the flames and extinguish the fire. If beams of electricity are fired at flames, the flames quickly go out, as if water had been sprayed over them. A 600 watt amplifier connected to a wand is used to deliver the electrical beams. On the basis of the work carried out, backpacks are being developed for firemen who could be shooting electricity beams at the fires. In the same way, buildings can be fitted with electricity amplifiers on roofs, instead of water spraying, to extinguish fires. Such a system could save huge amounts of water wasted in extinguishing fires and avoid damage to buildings and contents.
Poor bio fuel is a strong energy
The fuels which could be achieved from wasted products. They may be in solid bio mass, liquid or gases. The material which could be taken through photosynthetic processes, they can be referred to solar energy source. In March 2011, aviation made a history, when an F-22 Raptor fighter jet aircraft flew using the bio fuel taken from mustard called ‘camelina’ mixed with a ratio of 1:1 with conventional jet fuel. The fighter aircraft said to be successful when it flew at the speed of 50 per cent grater than the speed of sound. The same experiment has been done from KLM and Japan airlines; they also used bio fuel of camelina in their aircrafts and it successfully. Camelina is widely grown in USA, usually as a formal crop. Bio fuel is cheaper than the conventional fuel, because the camelina is about $ 70/ barrel, whereas the conventional fuels are selling in market above $100/ barrel. How interesting!
Artificial leaves for energy
A lot of scientists have been trying to develop ‘artificial leaves’ for so many years. This will be a device that could use sunlight to split water into two elements, hydrogen and oxygen. The produced hydrogen can be stored in fuel cells and will be used for the production of energy. What will be role of artificial leaves? The natural leaves with algae and bacteria are able to carry out photosynthesis. By this process the carbon dioxide present in the atmosphere, with the help of sunlight energy produce compounds like sugars. Oxygen is released as a by-product of the reaction, this maintains the level of oxygen in the atmosphere and removes carbon dioxide from it and reduce the global warming, and provides food which is necessary for our survival. The yearly rate of energy taken by the process of photosynthesis is about 100 terawatts, which is about six times the yearly power consumption on our planet. In US the professor of Chemistry with his co-workers, now have developed a material which is thinner than a leaf and contains a couple of cheap catalysts that serves the purpose. If this leaf is placed on a gallon of water under sunlight and connected to a fuel cell; it can supply so much electricity which may be enough for a small household, for a day. The Scientists say that these types of leaves can produce 10 times more energy than a natural leaf.
Incredible artificial arm
The technology is advancing day by day and incredible inventions are coming into being. It is possible now for a disabled person to move his wheel chair or drive cars controlled by his own thoughts and his own brain. Two biomedical engineering students, of University in Toronto have developed an artificial arm that can be controlled by thought. This artificial arm will be powered by compressed air; this is easy to form and avoids the need of surgery that is necessary to fit artificial arm. The disabled person which will use this arm may send signals to it through a skull cap. This cap has sensors which ‘feels’ The change in blood flow in the brain, it Happen when the thought command is released. These signals are sent to a microprocessor in the arm which already has stored shapes for signals such as forward, backward, up and down. The microprocessor matches these signals coming from the brain with those already stored shapes in it for different movements and moves according to it.
Amazing plastic
How wonderful it is that, when you are driving and sitting on a car seat made of bananas, pineapples and coconuts? Why not as after all this is the amazing world of fantastic inventions. Most plastics are normally made from chemical reactions of particular chemicals. These chemicals derived from petroleum or natural gas. A group of researchers at the University of Brazil have now found that a new kind of plastic can be manufactured from materials such as pineapple stems, banana plants and coconut fibers. That is incredible!
This excellent type of material is prepared from these sources a pound of which can be used to prepare a hundred pounds of magical plastic. The resulting material is expected to be used in manufacture of plastics used in the automobile industry.
Strokes detector
We use sound waves through water technique, by submarines to detect the depth of the sea and to avoid other objects. Active sonar emits pulses of sounds and listens to the echoes that come back after striking to objects. Now sonar has been produced to detect strokes in human brains. There are sensitive sensors attached to the sonar which detects the pressure of waves generated by the blood vessels. This device is worn on the head. Irregularities in the blood flow caused by clots in blood vessels can be detected by conclusion of the resulting patterns. Strokes show a major cause of death all over the world and early detection of the problem is difficult. The sonar device will be a best tool for the physician to detect the nature of the stroke and the medication which necessary to overcome the problem.
