Technology to convert heat waste into electricity

Scientists have claimed a breakthrough in converting waste heat to electricity by developing a new thermoelectric material which they say is best in the world. The Northwestern University finding offers hope to tap the waste energy as nearly two-thirds of it is lost as heat. The material could signify a paradigm shift, as inefficiency of current thermoelectric materials has limited their commercial use.

With a very environmentally stable material that is expected to convert 15 to 20 per cent of waste heat to useful electricity, thermoelectric could see more widespread adoption by industry. Possible areas of application include the automobile industry, heavy manufacturing industries and places were large combustion engines operate continuously.
Waste heat temperatures in these areas can range from 400 to 600 degrees Celsius, the sweet spot for thermoelectric use. The new material, based on the common semiconductor lead telluride, is the most efficient thermoelectric material known.

It exhibits a thermoelectric figure of merit of 2.2, the highest reported to date. Chemists, physicists, material scientists and mechanical engineers at Northwestern and Michigan State University collaborated to develop the material. The performance of the new material is nearly 30 per cent more efficient than its predecesso

A Smart Bulb that is controlled by Mobile Phone

A group of young Australian inventors has given the humble bulb a snazzy upgrade. They have developed the worlds smartest light bulb that dims, changes color, strobes, switches on automatically, and can be fully controlled from a mobile phone. The inventors secured almost a million pounds in funding to manufacture a 42 light bulb that lets you have a disco in your kitchen, The Telegraph reported.

The LIFX light bulb will give users the power to quickly dim the lights for a romantic evening in or switch on the disco strobe for an impromptu rave. At 42 each with a lifespan of 25 years, the bulbs cost a staggering amount compared to normal energy-saving fluorescent bulbs, which can be picked up for as little as 2 and typically last for 10 years.
The project has, however, seen an astonishing level of support since it launched. Billed by company founder Phil Bosua as the worlds smartest light bulb, the bulb will screw into normal light fittings and function like a normal light bulb if you lose your phone. Traditional bulbs also use heaps of power and those energy efficient fluoro bulbs have that cold white light that we all hate, Basua said.

Being Aware of your Thoughts is Energy Alignment

We are the Creator of our story and the energy that flows within us is the magnet to attract our outer experience which matches the frequency or vibrational feeling attached to the thought. It doesn't matter if the thought is conscious or unconscious. It's all those unconscious, limiting beliefs that are holding us back from creating our life on Purpose and with Purpose. If you think life is a struggle, it will be a struggle. If you think you are tired, you will be tired. If you think you are happy, you will see things appear that make you happy. Our thoughts are like a big magnet - what we think is magnetized or attracted to us.

Blue Brain Technology

“Blue Brain” – The name of the world’s first virtual brain. That means a machine that can function as human brain. Today scientists are in research to create an artificial brain that can think, response, take decision, and keep anything in memory. The main aim is to upload human brain into machine. So that man can think, take decision without any effort. After the death of the body, the virtual brain will act as the man. So, even after the death of a person we will not loose the knowledge, intelligence, personalities, feelings and memories of that man that can be used for the development of the human society. IBM is now in research to create a virtual brain. It is called “Blue Brain “. If possible, this would be the first virtual brain of the world. With in 30 years, we will be able to scan ourselves into the computers.

We can say Virtual brain is an artificial brain, which does not actually the natural brain, but can act as the brain. It is possible by using a super computer, with a huge amount of storage capacity, processing power and an interface between the human brain and this artificial one .Through this interface the data stored in the natural brain can be up loaded into the computer .So the brain and the knowledge, intelligence of anyone can be kept and used for ever, even after the death of the person.
Today we are developed because of our intelligence. Intelligence is the inborn quality that can not be created. Some people have this quality, so that they can think up to such an extent where other can not reach. Human society is always need of such intelligence and such an intelligent brain to have with. But the intelligence is lost along with the body after the death. The virtual brain is a solution to it. The brain and intelligence will alive even after the death.

Safeguard your liver get vaccinated

Healthy, hygienic habit and vaccination can keep you away from Hepatitis A.

Hepatitis A is a liver infection caused by the Hepatitis A virus (HAV).Although not a fatal disease, hepatitis A can lead to physical weakness and severe exhaustion which can take weeks or months to overcome.

Symptoms:
The symptoms of hepatitis A range from mild to high fever, malaise, loss of appetite, diarrhoea, nausea, abdominal discomfort, dark-coloured urine and jaundice a yellowing of the skin and whites of the eyes. These symptoms are known to be more severe in adults than children.
Who is at risk:
Anyone who does not have a prior history of HAV infection or hasn’t been vaccinated against it runs the risk of contracting hepatitis A. Most HAV infections occur during early childhood.
Living amidst poor sanitation where the virus is widespread, injecting drugs, living in a household with an infected person, or being a sexual partner of someone with acute HAV infection and usage of sewage contaminated or inadequately treated water raises risks of getting the disease. It spreads from person to person through faecal-oral transmission and blood-borne transmission.
Treatment and prevention
There is no specific treatment for hepatitis A. Improved sanitation and hepatitis A vaccinations are the most effective ways to prevent this disease.
Adequate supply of safe drinking water and proper disposal of sewage within communities, combined with personal hygiene practices such as regular hand wash reduce the spread of HAV.
Vaccination is a must
As we Indians fall in the category of intermediate risk of HAV infection, also known as intermediate endemicity, where transmission occurs primarily from person to person in the general community, often with periodic outbreaks, hepatitis A can be controlled through vaccination programmes.Two doses of the vaccine, given at an interval of six months, can protect you from the infection for a period of 10 years. The vaccine can be given as part of regular childhood immunisation programmers after the age of one.
The vaccine is a must if you are suffering from a chronic liver disease, are a Haemophylic patient, a medical person working with or treating HAV patients, or are a homosexual male. Anyone above the age of one, who has never been inoculated against the hepatitis A virus, and wants to be safe, should also be vaccinated.

Easy Ways to Healthy Eyes

1. Eat greens. Ingesting lots of leafy green vegetables like spinach, collard greens and kale help avoid macular degeneration.

2. Commitment to doing eye exercises to improve vision, and committing to making the kind of dietary and lifestyle changes that can help you get rid of your glasses, will help you see; and it will assist you in many other areas of life as well.

3. Sunlight is extremely beneficial to the eyes. You receive less than 10% of the energy of the Sun if the rays are coming through a window or the lenses of your glasses, so go outside without glasses (especially without sunglasses) for at least 15 minutes a day. It's good for you!

4. Eat apricots and blueberries. Blueberries are associated with reduction of eye fatigue and apricots are rich in beta carotene and lycopene, both of which promote good vision.

 

5. Get plenty of Omega 3 fish oil. It helps clear eyesight and eye health. (Heart-healthy diets in general tend to be good for the eyes as well, since blood circulation is so important to eye health).

6. Pamper your eyes. Try placing two slices of soothing cucumber over closed eyes for 15 minutes. It cools and refreshes the eyes.

7. Drink tea. It’s thought that drinking tea might help to deter cataracts.

8. Incorporate the following three things into your life daily and make them a subconscious habit by doing them consciously until they stick in your brain: Blinking every 2-4 seconds, breathing from your stomach (see how shallow your breathing becomes when working on a computer. Eyes require a great deal of oxygen to function properly), and shifting your eyes from point to point rather than trying to see an entire object all at once.

9. Drink more pure, flat, filtered water and increase the amount of high quality oils you eat and you'll not just improve your vision, but also your overall health.

10. Give them a break. If you work at a computer, remember the 20/20/20 rule. Take a break every 20 minutes. For 20 seconds, look at something 20 feet away or farther. This allows your eyes to refocus and relax and prevents the blurry vision that can occur by staring at a computer screen for too long.

11. It's not so much about exercising your eyes daily as it is relearning the old habit of proper vision. Did you need exercises to see properly when you originally had perfect sight? No, you just looked at the world in a different way than you do now. The correct way to view the world is by performing the three habits mentioned in the article: Blinking, Breathing, and Shifting.

Be Aware of Google Doodle

The Google Doodle is those cool logos you see on the Google search page. These logos are often animated and interactive. The logos often coincide with major holidays or world events. Originally designed by Googlers the general public can now submit designs for the Google Doodle.

The first Google Doodle was made in 1998 by Sergey Brin and Lary Page for the "Burning Man Festival." They wanted to alert Google users of their absence in the event of a server crash at Google. From that point the Designs were made by designers not employed by Google until 2000. In 2000 an intern at Google was asked by Larry and Sergey to do the Google Doodle. Dennis Hwang was the intern they asked to do the Doodles. He has been doing the Google Doodle ever since with other Googlers.
Google Doodles violate a long accepted tenet of brand management: that a logo must be respected and used correctly and consistently at all times. A constantly changing logo was thought to reduce brand equity. While this may be true of many brands, Google has successfully defied the orthodoxy; the Google logo has constant charming, interactive engagement that gets much press and buzz.
The Google team has created over 1,000 doodles for our homepages around the world. A group of Googlers get together regularly to brainstorm and decide which events will be celebrated with a doodle. The ideas for the doodles come from numerous sources, including Googlers and Google users. The doodle selection process aims to celebrate interesting events and anniversaries that reflect Google's personality and love of innovation. The doodle team is always excited to hear ideas from users - they can email proposals@google.com with ideas for the next Google doodle.

1) Operating a Laptop with Eyes Only

For nearly 40 years, we’ve had the keyboard and the mouse.  But at the International Consumer Electronics, a company called Tobii, which was demonstrating a laptop with built-in eye-tracking software. (That’s Tobii, “with two eyes,” get it?)
Now eye tracking isn’t new. It is available, at huge cost, in the military, in specialized industries, for disabled people, and so on. But it’s one thing to pay millions for a heads-up display in a fighter jet, and quite another to have it on your laptop.
The first demonstration was an Asteroids game, in which you’re supposed to blow up incoming asteroids just by looking at them. You discover that Tobii’s system works perfectly, flawlessly, exhilaratingly. Your hands are free, your body is relaxed, and you’re blowing up space rocks instantly with nothing but the awesome power of your gaze.

On a PC running Windows 8, you could click toolbar buttons in Word, click tile buttons and swipe through screens, all using your eyes. In an architecture-design program, you could effortlessly move around a large blueprint with your eyes, using the mouse’s scroll wheel to zoom in at any point. (For the disabled, Tobii makes a kit that lets you “click the mouse” by blinking or staring, but the system really works best in conjunction with a regular trackpad or mouse.)

Self-Defense Tactics

Being aware of your surroundings as you are walking to your vehicle is one of the most important things in your day to day life to protect yourself and avoid a self-defense situation. If you park in a garage where you work and are assigned a space, become aware of the vehicles parked around your vehicle. If possible, get to know the other vehicle owners. New friends are always a positive thing in your life. You will be more conscious of an out of place vehicle or person in your area if you know those who should be there at any given time.

Have your keys ready as you approach your vehicle. Taking time to find your keys when you reach the vehicle presents an opportunity for an attack. If you feel you are being followed as you walk to your vehicle, do not go to your vehicle. Continue to a populated area and summon help. It might seem like a good idea to get in the vehicle and lock the doors but if an assailant has some type of weapon they could smash a window and you would be in an undesirable position to defend yourself.
When and where possible back your vehicle into parking spaces. This allows for a quick getaway if the need arises. It also gives you an opportunity to check backup lights, brake lights, turn signals, etc. if there is a wall behind your vehicle. It also allows you a clear view to see if someone is approaching your vehicle after you have gotten into the vehicle. It is much easier to see out the windshield than it is out of the rearview mirrors.
These same ideas apply if you park in an open area or a garage at your place of residence or at the local shopping mall or grocery store. Self-defense is an ongoing process of awareness of the situation you are currently in. the more you are able to be aware of your surroundings the better you can protect yourself, your property and others.

Beware of Fast Food

Thirty-five experts from fifteen countries in Paris have developed a document urging the food industry to transform their cooking processes to minimize the presence of carcinogenic, and alert while the dangers of fast food. The so-called fast food, which includes pre-cooked with fat meat, different kinds of fried foods, bakery products are rich in carbohydrates and high caloric beverages with artificial sweeteners.

Take McDonald's, Burger King, and the Habit for example. They all sell a veggie burger. But that veggie burger patty (if the patty itself is not entirely vegetable based) is cooked in ANIMAL LARD number one, and number two, cooked on the same grill that meat (DEAD ANIMAL FLESH) is cooked on. All meat contains parasites and worms, and the ugliest ones that you could ever see with the human eyes.
Some people may think that they were avoiding animal byproducts by only eating French fries from the fast food restaurant, not knowing that most fast food restaurants such as McDonald's were cooking their fries in vegetable oil mixed with beef juice. McDonald's add beef juice to its cooking oil for flavor, in addition to spraying the fires with a sugar solution, freezing them and shipping them off to McDonald's franchises, and after cooking the sugar sprayed fries in beef juice (oil), sodium chloride (salt) is added and you have one of the most addictive products in America - McDonald's French fries.
Chemicals being used in the production of some of our most-popular foods:
Propylene glycol: This chemical is very similar to ethylene glycol, a dangerous anti-freeze. This less-toxic cousin prevents products from becoming too solid. Some ice creams have this ingredient; otherwise you'd be eating ice.
Carmine: Commonly found in red food coloring, this chemical comes from crushed cochineal, small red beetles that burrow into cacti. Husks of the beetle are ground up and forms the basis for red coloring found in foods ranging from cranberry juice to M&Ms.
Shellac: Yes, this chemical used to finish wood products also gives some candies their sheen. It comes from the female Lac beetle.
L-cycsteine: This common dough enhancer comes from hair, feathers, hooves and bristles.
Lanolin (gum base): Next time you chew on gum, remember this. The goopiness of gum comes from lanolin, oils from sheep's wool that is also used for vitamin D3 supplements.

Silicon dioxide: Nothing weird about eating sand, right? This anti-caking agent is found in many foods including shredded cheese and fast food chili.

5) Heart disease risk from watching television, researchers warn

British researchers have found that if the average of four hours of television a day in the study were reduced to one hour, then eight per cent of deaths from heart disease could have been prevented.

As Britons are glued to the TV for the World Cup, it was found that every hour of television watched per day increase the risk of dying from heart disease by seven per cent.

The link between TV and heart disease was still strong even when lack of exercise, obesity, diet and smoking were taken into account.

It means that watching TV was independently linked to heart disease and the effect is not simply due to be inactive while watching television.

The research conducted by the Medical Research Council studied more than 13,000 healthy middle aged men and women in Norfolk.

Over the 10 year study, 373 of the 13,197 participants or one in 35 died from heart disease.

Of these deaths 30 could have been prevented if the average person watched one hour of television per day instead of four.

Dr Katrien Wijndaele co-author of the study from the MRC warned: “Our bodies are not designed to sit for long periods and we should be aware that, as we put in the TV-hours watching the World Cup, our risk of heart disease is probably increasing.

"It might seem obvious that watching TV is linked to heart disease but it’s really crucial that we look closely at how our lifestyles affect our health in order to develop more effective ways of improving the health of the nation. This type of research is a crucial part of informing public health advice.

“We need further research to see if other sedentary activities, like sitting behind a computer or in the car, generate the same results. However, we chose to focus on TV as it’s the most widespread sedentary leisure activity where people have an active choice to dramatically change their behaviour.”

6) Five guidelines to deal with..

You have a mind of your own. Doctors can't know everything. Perhaps some people trust doctors a little too much. They expect miracles and then blame the doctors when things turn out to be less than what they imagined. That's not fair to you or the doctor.

So here are a few simple things to keep in mind when you are dealing with medical issues
Step 1: Listen to your body. It's always sending you signal. If it doesn't "feel right" then it's time to re-evaluate your options.

Step 2: Get a third and fourth opinion on major a major diagnosis. For example, your doctor tells you that you have major disease. Confirm with another physician.

Step 3: Research your medical situation. The internet is packed with information. Go to discussion groups about your medical issue. Go to websites. Print out journals. Dig Deep. Why be in the dark about what's happening with your body? This is your life!

Step 4: Ask your doctor questions. This is why you pay the doctor. If he or she is worth anything, he or she will be happy to answer your questions and give you ways to find out more information. Some doctors use a sliding-scale fee system. They will charge more if you ask more questions. Find out the cost before your consultation.

Step 5: If your doctor gets offended or displays an overly-negative reaction towards your questions, find another doctor. You need a doctor in whom you can place your confidence.

7) D-roll Laptop

The D-roll Laptop is designed like an artist’s tube, which contains a roll up OLED screen and a cool slide out keyboard; it also has a mouse and a web camera which are used as the end caps for the case. It is designed by Hao Hua. This is a really cool design, it would be great to have a laptop that worked and looked like this, but I think this is probably a few years away yet.


D-roll is a next generation concept laptop design which is way distinctive from usual laptops in both shape and function. The long tube shape of this laptop, which was inspired from the storage tubes that artists are using for storing large drawings, eliminates perception of the traditional book looking laptops. This multifunctional laptop has two working modes. When it is operating in full function mode, the laptop is unfolded completely and all peripherals are turned on. The main display is turned off and a smaller screen, attached with main body is turned on allowing the users to check and send mails when D-roll is under email mode. VC is a helpful add-on for capturing pictures or videos and Locking System can provide certain security to the laptop.
D-roll set up like a regular laptop, and it's easy to imagine how portable it'd be all rolled up. There's an in-between configuration that you could theoretically use to browse email quickly, and the straps double as places to plug in your USB devices. It also has a detachable webcam you could use on the computer or wear on your wrist. Rather than carry around a notebook in a laptop bag, full to the brim with all manner of cables, the Rolltop concept proposes bringing everything together in a flat panel display that's wrapped around a central cylinder. The top of the column detaches and acts as a power plug while the carry strap doubles as a power cord.

8) Be Aware of Your Breathing

Emotional state and breathing mirror each other. Paying attention to emotions and breathing can help people identify and alter their responses. Fear, anger, and sorrow are the usually the most challenging emotions, and are often reflected in breathing in the following ways:

• Fear: When people feel afraid, they tend to hold their breath, breathe through their chests or, in extreme cases, hyperventilate. This elevates the stress level in the human body, and decreases the immune system’s ability to fight off illness.
• Sadness: When people feel sad, they inhale forcefully, but exhale weakly (an example of this is  expressed as sobbing). This inhibits the ability to breathe freely and to exude energy.
• Anger: When people feel angry, they exhale more forcefully than they inhale. This is a defensive state that renders people unable to receive or accept incoming information or energy.

In the midst of a busy day, a cleansing breath is an effective way to release negative energies and return to a place of balance and equanimity. When people exhale, they breathe out not only carbon dioxide and waste gases, but also mental and emotional toxins, concerns, worries, sorrow, anger, and fear.
When people inhale, in addition to oxygen people also take in life energy, light, love, happiness and inspiration. Consciously focusing on inhaling, even for a few breaths can become an exercise of healing and balance.

Purifying Breath Exercise

To become more mindful of your breathing, try this exercise:

• Inhale into a soft belly, taking in light, love, and healing energy. Picture this as clear, bright, or sparkling. Feel yourself becoming brighter as you fill with light and joy.
• Exhale fully, releasing any negative states or feelings. You may picture it as darkness or a fog. If you have anger, fear or sadness, breathe them out. If you have tension, anxieties, or worry, release them as you exhale.

EFFECTS OF CELL PHONE ON HEALTH

EFFECTS OF CELL PHONE ON HEALTH

Mobile phone hand sets are used close to hand. It absorbs some of radio waves. Researchers of Finland are warning that the use of hand -held cellular phone might cause brain tumor. Scientist from the radiation and nuclear safety authority has found the exposure of human cells to mobile phone radiation can damage the blood brain barrier. The exposure causes the cells in blood vessels walls to shrink, which enables molecules to pass into brain tissues. The effects are headache, earache, sleeplessness, memory loss or even cancer.

Most of the electromagnetic equipment such as mobile phone generats electromagnetic field . some of these devices creates low- frequency Electromagnetic field while some such as mobile phone creats high frequency EMF. Since the radiation is ionizing its energy is enough to rapture intra -and inter -molecular links in tissues.The cellular system has many base station , which share a number of microwave frequency.Each base station sends and receives signals from a small areas called a cell. Cell phone converts sound into radio -wave and transmit these and also receives radio signals and converts these into sound wave.

Few companies are designing filters that fit into the cell phone and reduce emissions. Keeping the cell phone away from the head also reduce the exposure to radiations.

Ultimately, the law of nature holds supreme that every beautiful flower has thorn underneath it.

OmniTouch

OmniTouch is a depth sensing and wearable projection system introduced by Microsoft. The device provides an interactive, graphical and multitouch input on arbitrary surfaces (table tops, hands, arms, legs, paper, etc). It uses 3-D motion sensing and a projector to provide a touch screen on any surface. It is the first functioning technology that allows users to create and interact with images in a 3-D space.

OmniTouch requires the user to wear a shoulder mounted projector, which projects the touch screen on surfaces based on the user choice and tracks the hand movement for input. The device can then recognize the button press on the projected surface and the gestures in 3D space. It provides the user a larger area of interaction instead of confining them to a tiny screen. It is estimated that the bulky shoulder mount in the initial versions will be brought down to smaller sizes in future release of OmniTouch.

The short-range camera provides a 320x240 depth map at 30 frames per second. Objects as close as 8 inches can be easily imaged, with a relative error of 0.2 inches. However, the depth accuracy decreases and noise increases with an increase in distance. The projector provides a wide angle, focus-free projection of graphical elements, regardless of the distance from the projector. The camera and projector are mounted to a metal frame, which is worn on the user’s shoulder, and is secured using a chest strap. The projector and camera are tethered to a computer for prototyping.

iOS

iOS

iOS is Apple's mobile operating system used to run the popular iPhone, iPad and iPod Touch devices. Formerly known as the iPhone OS. iOS utilizes a multi-touch interface where simple gestures are used to operate the device, like swiping your finger across the screen to move to the next page or pinching your fingers to zoom out.

iOS has gone through multiple updates, with recent updates adding the ability to create folders for app icons and the ability to multi-task. The updates are generally free for iPhone and iPad users, while iPod Touch users are sometimes required to pay a nominal fee.

iOS allows iPad apps to utilize certain tasks in the background without being a major drain on memory and processing power. It also allows us to organize our apps into folders. This is great for those who had page after page filled with icons. Another huge feature in the iOS update was the ability to print from our iPad. AirPrint works with AirPrint-enabled printers available from HP.

iOS introduced a host of new email features, including a unified inbox and threaded email discussions. The iPad now supports multiple ActiveSync accounts, which is good news for those with multiple Microsoft Exchange accounts.

. This allows us to stream our movies and music from our PC/Mac to our iPad without taking up precious storage space on your tablet.

Wireless Power

Wireless power

Using the principle of electromagnetic induction, by which an electrical charge can be stimulated in a wire coil by placing another one nearby, the crazy boffins were able to display wireless power transfer.

Despite being high voltage, they said, it was safe, efficient and could be applied to any surface. The demo room consisted of a kitchen without plugs, but full of lights that could be stuck anywhere and a frying pan that heated up just by sitting it on the counter. Put a phone on the same counter and it began charging. Clearly, this was the future.

The good news is that the Wireless Power Consortium are going to be finalising a standard for wireless power called Qi later this year, which should mean prices drop and manufacturers have the confidence to build the technology straight into devices, rather than requiring an adaptor. It's a tiny dongle that can turn Wi-Fi signals back into electricity for charging phone batteries and the like.
