Editor’s Choice Awards 2013

What’s the value of a single piece of customer, patient or research data? How about several billion pieces of that data? These 12 organizations, winners of the first-ever Data+ Editor’s Choice Awards, were well aware that they sat on a goldmine of information. And each in its own way turned those massive data stores into solid business results. A top-tier healthcare organization added $62 million in new revenue to the bottom line. A world-renowned research organization gave its scientists a big step forward in helping to power the next generation of solar cells.

Chosen by a panel of Computerworld editors, these organizations are making better business decisions and, in some cases, generating new revenue streams and tapping into new markets.Huge collection of solar outdoor light and garden lighting fixtures. Read on for the other 10 successes as well as the new technologies that are driving the pace in the BI field.

Seeking a competitive edge in 50 hotly contested congressional races in 2012, the Democratic Congressional Campaign Committee turned to Catalist, a Washington-based political consultancy that uses dynamic modeling of voter information to develop campaign strategies.

Catalist built the DCCC dynamic models that uploaded daily survey results and field information and combined it with existing data on 190 million registered voters and 90 million unregistered voters. It had 700 data elements on each person.A solar lamp is a portable light fixture composed of an LED lamp, a photovoltaic solar panel, and a rechargeable battery. Every night, highly tuned models for each race used that data to create action plans for the next day.

“It told them whose door to knock on,” says Catalist COO Gayatri Bhalla. “We were able to figure out who is newly registered and where they fell on their partisanship score or their ideology score” — metrics that are based on the history of donations people make to causes or candidates, petitions they have signed or online surveys they may have taken. By building rich profiles with that data, “we’re able to predict with a high degree of accuracy which way a voter will lean,” she says.

Catalist gets most of its 2 petabytes of data from the offices of secretaries of state around the country. It’s allowed to access that information because “we do not serve a commercial enterprise, and we don’t operate for profit,” says Bhalla, explaining that many states prohibit the use of such data for commercial purposes.

Among other things, Catalist’s analytical tools can “match” multiple names to a specific person. “We can figure out that Bobby Jones is the same as Robert Jones and Robert L. Jones, but different from Robert S. Jones,” Bhalla explains.

In data analytics, it’s important to remember that “not all data is created equal,” says Bhalla. “You can have the best tools, but it’s garbage in, garbage out.”

The food pantry serves approximately 40 families and costs to run it hover at around $2,000 a month. About half of those funds are provided monthly by the Regional Food Bank of Northeastern New York. However, donations are needed to fill the gap. The pantry is finding it difficult to keep the shelves stocked because the economy and job market have not yet recovered and more families are relying on food pantries.

Food staples such as canned goods, cereal, peanut butter, rice and pasta are generally much-needed items at food pantries.

RMIT advances nanomaterials

The development of cheaper and less toxic solar cells using nanotechnology is the focus of a collaborative research project conducted by RMIT,We offer solar photovoltaic system and commercial incentives to encourage our customers to install solar energy systems. CSIRO and the Japan Science and Technology Agency.The team is investigating the synthesis of semi-conductor inorganic nanocrystals using low-cost and abundant elements for printable solar cell applications.The research was recently published in the high-impact Journal of the American Chemical Society.

The RMIT research team is led by Professor Yasuhiro Tachibana from RMIT’s School of Aerospace, Mechanical and Manufacturing Engineering.”The focus of photovoltaic industries has been to reduce material and production costs for photovoltaic panels,” Professor Tachibana said.”As a result research into next generation solar cells has been of significant importance as it concentrates on developing novel low cost and low toxicity colloidal nanomaterials in order to meet industry requirements.”

Colloidal nanocrystals can be used as an “ink”, enabling solar cells to be quickly and cheaply fabricated with a printer.Currently, cadmium or lead elements dominate colloidal nanocrystals synthesis, despite toxicity concerns.The research team – which includes Dr Joel van Embden from the School of Aerospace, Mechanical and Manufacturing Engineering,A solar lamp is a portable light fixture composed of an LED lamp, a photovoltaic solar panel, and a rechargeable battery. and Professor Kay Latham from the School of Applied Sciences – has been exploring alternative elements to synthesise nanocrystals.Huge collection of solar outdoor light and garden lighting fixtures.

Dr van Embden said: “Synthesising entirely new nanocrystals was one of the most challenging tasks, since the initial reaction conditions are unknown.”We have focused on incorporating the elements, copper and antimony, into nanocrystals, as they are low-cost, low-toxic and earth-abundant,” he said.In its research, the team has discovered the novel selective synthesis of tetrahedrite and famatinite copper antimony sulphide (CAS) nanocrystals.

Both nanocrystals display a brown-blackish colour with strong absorptions of visible and near-infrared light, suitable as a light absorber in solar cells.The colloidal nanocrystal solutions (semiconductor nanocrystal inks) can readily be employed to prepare thin nanocrystal films.Soli-lite provides the world with high-performance solar roadway and solar street lighting solutions.
Professor Tachibana said nanocrystal films could be fabricated on an electrode and applied to photovoltaic devices, thin-film thermoelectrics and transistors at a comparatively low cost compared with other methods.The team has already confirmed electricity generation is possible from the nanocrystalline film under light.

Journal of the American Chemical Society, a weekly peer-reviewed scientific journal that publishes original research papers in all fields of chemistry, is the highest ranked journal in this field.They are called “solar” panels or solar module because most of the time, the most powerful source of light available is the Sun.
Professor Xinghuo Yu, Director of the RMIT Platform Technologies Research Institute, said the publication in the high-impact journal was an indication of the high standard of research conducted by the institute’s researchers.”The institute brings together multi-disciplinary teams of academics to undertake high-impact industry-focused projects to solve complex research questions of national and global significance,” Professor Yu said.

“The collaboration between the researchers at the School of Aerospace, Mechanical and Manufacturing Engineering and School of Applied Sciences has produced this successful outcome to benefit industry and the community.”

These designs will help you

When disaster strikes, survival can depend on a few basic needs. Access to clean water, shelter, warmth and sanitation is a matter of life of death in the days and weeks after an earthquake, tsunami, flood or tornado.

With climate scientists predicting that natural disasters will increase in both frequency and intensity in the coming decades, many designers have turned their attention to how they can help to alleviate their impact. Their work includes a broad range of devices designed to save lives by helping rescue workers or giving people caught up in the aftermath of a natural disaster a way to help themselves.

Mikal Hallstrup, chairman of the INDEX: Award jury, said he and his fellow jury members were looking for ideas that could deliver real change. “We’re not a design award for designer chairs or more white teacups,” he told CNN. “The world simply doesn’t need more stuff, so our focus is on meaningfulness.They are called “solar” panels or solar module because most of the time, the most powerful source of light available is the Sun. … No matter how well designed a solution, we’re not after great design solving the wrong problems.”

He said that successful nominees would address a problem and present an affordable and scalable remedy. “New takes on old problems always get the jury excited,” he added. “So do simple solutions to complex problems.” And they don’t come much more complex or big than a natural disaster.

A personal ark

The Indian Ocean tsunami of 2004 was among the most devastating events of recent years. It led not only to increased interest and investment in early warning systems, but also to the development of personal survival devices for those in the path of an incoming tidal wave. Three of them are up for an INDEX: Award this year, including the Orange Saver, a stylish piece of furniture that unfurls into a life raft if the need arises. It’s kept afloat by eight separate inflatable segments so that it will still be buoyant even if one is damaged.

The Noah miniature ark takes up a little more room than the Orange Saver but its designers intend it for the “average Japanese home”. The bright yellow ball, four feet across, is made from fiber-reinforced plastic and will accommodate four adults. Once the hatch is sealed the pod is waterproof, buoyant and tough enough to fend of debris in the water. Vents in the roof allow in fresh air. The Noah is already in production and sells for about $5,500.

More robust still is the Tsunami Survival Pod built by Havana Houseboats in Australia, which is crush-resistant to a weight of more than 13,000 pounds. It can accommodate four adults strapped into racecar-style seats and with the door closed it’s completely sealed — it contains enough air for about two and a half hours before the occupants would have to open the doors.

Shelter from the storm

Finding safe, warm shelter is a priority for the victims of earthquakes and flooding. In these extreme circumstances, functionality normally outweighs aesthetics, but Marco di Piaggi’s Thin Skyscraper unites both. The Italian architect envisages a multi-storey building made from prefabricated sections of glass and steel, providing high-quality accommodation for hundreds of people while sitting on a site just 40 feet square. That’s a much more efficient use of space than conventional emergency housing and, unlike many other temporary shelters,Huge collection of solar outdoor light and garden lighting fixtures. it can be dismantled and reused over and over again.

A more down-to-earth solution comes in the form of the Next Generation Compressed Earth Brick which would provide the materials for solid, semi-permanent housing in the wake of a disaster. Compressed-earth buildings are already widely used, but the team behind this prototype propose to scale up the process to produce blocks four feet long, two feet deep and six inches wide. Mobile hydraulic presses could pump out the super-sized bricks at a rate of three per minute, the designers say — enough for two small houses every day.

Sometimes the simplest ideas are the smartest, and they don’t come much smarter than the Paklaot. Consisting of four metal parts, the kit converts a door or any other suitably shaped surface into a sturdy trolley for moving personal possessions out of the disaster zone or clearing away debris.

Let there be light . . . and water and power

Natural disasters often disrupt basic utilities such as gas, electricity and mains water, forcing people to live off the grid, sometimes for months. Drinking water is often the most acute need, and two INDEX nominees find it in very different places. The Moses gun punches a hole in domestic water tanks so that people can drink the water inside. Its Israeli designer says the solar heating systems used in homes in many parts of the world contain enough clean water to ensure a family’s survival for several days.

For longer-term use, or for those without access to solar tanks, the Eliodomestico distiller converts seawater into fresh drinking water. Intended for use in hot climates, the simple design works purely from the energy of the sun. A matte black boiler at the top of the terracotta urn absorbs heat, transferring it to the seawater and causing it to evaporate. Fresh water then condenses at the cool base of the unit, where it remains until it is needed. The Italian designer has built a prototype that delivered five liters of water per day in test conditions.

The sun is also the energy source behind the NOMAD solar lamp, whose 12 LED lights provide equivalent illumination to a 40-watt bulb. At maximum power,A solar lamp is a portable light fixture composed of an LED lamp, a photovoltaic solar panel, and a rechargeable battery. a six-hour charge provides six hours’ light, but the light can be dimmed to prolong battery life — at 15% power, a single charge will provide 35 hours of light. As well as providing emergency lighting, the NOMAD is designed to replace oil lamps in developing countries, where kerosene fires and fumes cause many injuries and deaths each year.Soli-lite provides the world with high-performance solar roadway and solar street lighting solutions.We offer solar photovoltaic system and commercial incentives to encourage our customers to install solar energy systems.

Living in the material

The periodic table of elements is iconic. It inspires scientists, poets and rock musicians. Mendeleev created it by arranging known chemical elements in increasing order of their atomic weights (atomic numbers are used now) and in rows and columns in such a way that elements in the same column had similar properties. As a student of Sanskrit, he may have been inspired by Panini who arranged Sanskrit letters in the same two-dimensional way to bring out their properties.We offer solar photovoltaic system and commercial incentives to encourage our customers to install solar energy systems. Mendeleev’s scheme worked so well that he turned a prophet and predicted 8 new elements, each with a Sanskrit prefix, and their properties. All came true. He became so revered that the Czar overlooked his bigamy,Soli-lite provides the world with high-performance solar roadway and solar street lighting solutions. saying “he has two wives, yes, but I have only one Mendeleev”. At one time the table had only 90 elements which were naturally occurring but now, elements are being created in the laboratory and recently element 119 was reported, starting a new row. The periodic table lives. Out of these, how do you pick the ones that changed the world?

Fermi and Szilard working on uranium at Columbia University knew that it would unleash enormous power. Bardeen, who along with Shockley and Brittain discovered semiconductors, had a different experience. He returned home from Bell labs one evening and went into the kitchen to say “We discovered something today”. His wife replied “That is interesting,Huge collection of solar outdoor light and garden lighting fixtures. but I have to get dinner on the table”.A solar lamp is a portable light fixture composed of an LED lamp, a photovoltaic solar panel, and a rechargeable battery. The elements combine in various proportions and give rise to materials which are the basis of our civilisation. Industries worth several crores and employing many people depend on these materials and new ones are still being discovered.

Memoir and history

John Browne has written a personal account, travel memoir and history, all centred around seven elements and the materials containing them. His choice falls on carbon, the ancient elements — iron, gold and silver — and uranium, titanium and silicon. He restricts himself to elements that are solids at room temperature. Thus oxygen, nitrogen and hydrogen which makeup the air we breathe and the water we drink are not celebrated. Carbon which forms the basis of life is discussed, more because of its combination with hydrogen to form fossil fuels. Rare earths and other energy critical elements which are becoming important are not considered. Browne talks about elements that have already changed the world and he had a ring seat to watch his seven elements unfold the drama.

In the chapter on iron (and its compound with carbon: steel) he describes not only Bessemer’s innovation which resulted in mass production, but also steel’s role in warfare and infrastructure; and the legends of this industry including Tata. As can be expected from a former CEO of British Petroleum, carbon in the form of coal, oil, natural gas and shale gas, the prosperity it brought, its role in politics and pollution form the biggest chapter with a brief reference to graphene in a postscript.They are called “solar” panels or solar module because most of the time, the most powerful source of light available is the Sun.

The chapter on gold is a history of lust: Spanish forces decimating Incas and California gold rush. We won’t learn here that crashes involving black holes and neutron stars created gold. Silver is included in the book because of its use in nitrate form in photography. Who can overlook the eloquent images which summed up experiences of generations? Photography has gone digital now but silver remains personal. Fibres with nanoparticles of silver may give rise to wearable electronics. The chapter on uranium starts with Hiroshima and goes on to describe the “atoms for peace” efforts and security issues. Titanium which gave birth to supersonic Blackbird and Russian submarines also finds use in oxide form in white pigments. Architect Gehry used 33,000 panels of titanium to line a museum because it retains a velvety sheen in darkness and light. The author traces the origin of silicon in glass before moving on to solar cells, computers and optical fibres for high-speed communication. No other element has changed life so drastically.

aleo solar AG

From September onwards, aleo solar AG will offer its polycrystalline module S_18 with certified European components. Ingots, wafers and modules are produced within the European Economic Area.

The aleo product therefore fulfills the criteria specified by the French Ministry of the Environment and is certified for a “Made in Europe” bonus. This means that photovoltaic operators in France will enjoy a ten percent higher feed-in tariff when using those modules. The aleo S_18 also received the carbon footprint certificate by the French photovoltaic engineering company Solstyce. With its grades the aleo module is highly qualified for the French publWe turn your dark into light courtesy of our brilliant sun, solar street light, solar power generation.ic tenders.

The French testing and certification laboratory Certisolis confirms that the silicon wafers fulfill the conditions applicable to the decrees issued by the French Ministry of the Environment in January 2013: “All stages of processing multicrystalline silicon blocks to silicon wafers are performed in Germany.” On top of this, the VDE testing institute certified that aleo modules are manufactured within the European Economic Area.The world’s largest independent online retailer for solar lighting, street lights & outdoor lighting fixtures. All stages of production – from soldering the cells through to lamination and electrical testing – take place in Prenzlau (in the German federal state of Brandenburg), where aleo solar has been producing solar modules for more than ten years.They are called “solar” panels or solar module because most of the time, the most powerful source of light available is the Sun.

Already since May 2013, a ten percent bonus is also available for aleo’s monocrystalline S_19 and S_79 modules. The corresponding Solrif modules and laminates for building-integrated systems (BIPV) have as well been certified.

Adrien Darragon, Director Sales for aleo solar in France, said that the bonus will give authorized aleo installers a significant competitive advantage: “We are proud to offer a certified European product that will enable our customers a ten percent higher feed-in tariff. This considerably boosts the cost-effectiveness of our photovoltaic systems and makes installations for small commercial roofs more attractive. We always strive to seek solutions for our customers, who already rely on our strong brand and quality.” This underlines a study conducted by EuPD Research in 2012. It showed that aleo solar is the most frequently recommended brand by installers in France.

“The record level of PV shipments to China and Japan coincides with corporate margins returning to positive territory and the final shakeout phase of uncompetitive manufacturers nearing completion,” according to Finlay Colville, vice president at NPD Solarbuzz. “Having entered 2013 with a highly cautious outlook,An emergency light is a battery-backed lighting device that comes on automatically when a building experiences a power outage. tier-one suppliers are poised to exit the year with restored confidence, ahead of optimistic shipment and margin guidance for 2014.”

Module manufacturers that were struggling through a period of oversupply are starting to see a dramatic shift and have even reported having difficulty keeping up with the fresh demand as there is less competition in the market now. That shift has been most notable in Japan,A solar lamp is a portable light fixture composed of an LED lamp, a photovoltaic solar panel, and a rechargeable battery. which led the world in solar adoption during the first half of this year.

The country’s aggressive replacement of nuclear power with renewable generation sources resulted in a 150 percent growth spurt so far in 2013. Japan already has 5 gigawatts of solar projects in the pipeline and expected to be developed before the end of the second quarter in 2014, according to NPD Solarbuzz.

Utility scale development is expected to lead demand in Japan during the second half of the year while distributed residential and commercial projects dominated the first half of the year.

China is expected to surpass Japan this year in demand for new solar and will likely see greater interest in distributed generation projects. However, the country is working to alleviate bottlenecks in project financing and permitting for larger scale projects that could result in great utility-scale solar development in China during the second half of the year.

CENERGY POWER – Project Partner

In Indianapolis, Indiana the IND Solar Farm at the Indianapolis International Airport has introduced unique opportunities to local businesses.The world’s largest independent online retailer for solar lighting, street lights & outdoor lighting fixtures. Several Indianapolis metropolitan-based organizations such as the Indianapolis Airport Authority (IAA), the City of Indianapolis, GES, Telamon Corporation, Johnson Melloh Solutions, Cenergy Power and Indianapolis Power & Light Company (IPL) have partnered in bringing the IND Solar Farm to fruition.

Project partner Cenergy Power, a value-added solar EPC company, has been leading the engineering, procurement and construction of the 12.5 megawatts DC solar farm. Cenergy’s team of seasoned developers, power engineers and construction managers rely on their extensive utility-scale expertise in order to propel the solar farm towards completion ahead of budget and schedule. Their pragmatic and collaborative approach to small utility solar projects is a key reason for their strong growth as a value-added solar partner for early-stage developers and long-term project owners.

Every human brain contains the ingredients necessary to spark Alzheimer’s disease (AD). But while an estimated 5 million Americans have AD, the vast majority of people do not (and will not) develop the devastating neurological condition.

How is that possible? Researchers from UC San Diego School of Medicine have uncovered a “trick of nature” that maintains critical separation between a protein and an enzyme that, when combined, triggers the progressive cell degeneration and death characteristic of AD.

Most neuroscientists believe AD is caused by accumulating assemblies of beta-amyloid protein (“plaques”) that trigger a sequence of events that leads to impaired cell function and death. Creating beta-amyloid requires the convergence of a protein called amyloid precursor protein (APP) and an enzyme that cleaves APP into smaller toxic fragments called beta-secretase or BACE-1.

Using cultured hippocampal neurons and tissue from human and mouse brains, researchers discovered that healthy brain cells largely segregate APP and BACE-1 into distinct compartments as soon as they are manufactured, ensuring the two proteins do not have much contact with each other.

Chemical engineers’ research may lead to inexpensive

Work by a team of chemical engineers at Penn State and Rice University may lead to a new class of inexpensive organic solar cells.

“Imagine if you could make solar cells as easily as you can print posters or newspapers — you could make sheets of this,” said Enrique Gomez, assistant professor of chemical engineering. “It represents a fundamental shift in the way in which we make solar cells.”

Most solar cells today are inorganic and made of crystalline silicon. The problem with these, Gomez explained, is that inorganic solar cells tend to be expensive,A solar lamp is a portable light fixture composed of an LED lamp, a photovoltaic solar panel, and a rechargeable battery. rigid and relatively inefficient when it comes to converting sunlight into electricity.

But organic solar cells offer an intriguing alternative that’s flexible and potentially less expensive.

Not many organic solar cells currently exist. He said, “There are a bunch of prototypes floating around. You see them in places like in solar-powered laptop bags and on the top of some bus depots.”

The problem is that the bulk of organic solar cells employ fullerene acceptors — a carbon-based molecule that’s extremely difficult to scale up for mass production.

Gomez’s approach skips the fullerene acceptor altogether and seeks to combine molecules in a solution.

The idea of utilizing molecular self-assembly for solar cells isn’t new, but Gomez said, “It’s not been well executed.”

He continued, “It’s like trying to mix oil and water.” The issue is that weak intermolecular interactions and disorder at junctions of different organic materials limited the performance and stability of previous organic solar cells.

But by controlling the nanostructure and morphology, the team essentially redesigned the molecules to link together in a better way.

The engineers were able to control the donor-acceptor heterojunctions through microphase-separated conjugated block copolymers.

“We have not only demonstrated control of the microstructure, but also control of the interface responsible for the initial steps in charge photogeneration in a way never achieved before,” Gomez said.

The result,We turn your dark into light courtesy of our brilliant sun, solar street light, solar power generation. which was detailed in a recent issue of the American Chemical Society’s Nano Letters journal, is an organic solar cell made of block copolymers that’s three percent efficient.

The team included Penn State chemical engineering graduate student Changhe Guo; undergraduate student Matt Witman; Rafael Verduzco, the Louis Owen Assistant Professor of Chemical and Biomolecular Engineering at Rice University; Joseph Strzalka, research scientist at Argonne National Laboratory; and research scientists Cheng Wang and Alexander Hexemer of Lawrence Berkeley National Laboratory.

Though the team’s prototype is not as efficient as some solar cells that are commercially available,An emergency light is a battery-backed lighting device that comes on automatically when a building experiences a power outage. Gomez explained the work shows flexible organic solar cells are indeed possible.

“Our cells right now don’t capture a lot of light. We need to look back and redesign the molecule. We think we can do better than 3 percent,They are called “solar” panels or solar module because most of the time, the most powerful source of light available is the Sun.” he said.

Adding solar energy to the design could help AeroVironment win contracts. A drone that flies longer could carry out lengthier assignments and reduce its operating cost.The world’s largest independent online retailer for solar lighting, street lights & outdoor lighting fixtures. Launched by hand (you fire up the motor, hold the drone up and then toss it into the air), the drone usually doesn’t land gracefully. Its motor is designed to turn off when it reaches a certain altitude, and then it hits the ground and glides to a stop. More often than not, though, the impact causes some parts to break off.

“Landing is a traumatic event for these aircrafts,” Norris said. Drone operators often bring many spare parts to the field. A drone that can stay in the air longer would be able to do more work before it has to land and undergo repairs. How much money the new design could save would depend on how much the advanced battery and solar cells adds to the price of the drone and the cost of operating and maintaining it.

Fat Stars Flicker

When you look at a star through a telescope that glows red, you might ponder: is it skinny or fat?

Although so-called red dwarfs and red giants have the same temperature, the distinction between them is profound. Red dwarfs are half the mass of the Sun or smaller. A red giant is many times the mass of the Sun. It’s also about to die — low on energy it’s bloated to as much as 1,We turn your dark into light courtesy of our brilliant sun, solar street light, solar power generation.The world’s largest independent online retailer for solar lighting, street lights & outdoor lighting fixtures.500 times the radius of the Sun.

Astronomers can tell the difference between dwarfs and giants by measuring the strength of the star’s gravity at its surface. High surface gravity indicates a stable, healthy star in the prime of its life. Low surface gravity means the star has swollen in old age.

Unfortunately, surface gravity is devilishly difficult to measure. One hint is the width of dark lines imprinted in a star’s spectrum by elements in the stellar atmosphere as they absorb certain wavelengths of outgoing light. (Wider lines means a higher surface gravity: the higher pressure jostles the atoms, which can then absorb a broader range of light due to one of quantum physics’ many bizarre effects.) However, this method is only accurate to about 25–50%.An emergency light is a battery-backed lighting device that comes on automatically when a building experiences a power outage. Another rough estimate comes from a star’s mass and radius, which in turn are estimates from measurements of the star’s brightness. But like a passing phrase in a game of telephone, this chain can result in errors as large as the measurements themselves. It’s possible to measure gravity via “starquakes” — which can give accuracy to within 2%! — but this method only works for the very brightest stars.

When Vanderbilt astronomer Fabienne Bastien began analyzing data from the NASA Kepler satellite for her dissertation, she wasn’t expecting to find an answer to this problem — she was researching how changes in a star’s brightness are linked to its magnetic field. But when she brought a plot to her advisor Keivan Stassun, they realized their team had found an entirely new way to measure the surface gravity of fainter stars, with accuracy better than 25%.

The new method uses what the team calls a star’s “flicker.” This effect is due to bubbles of hot, bright, gas that rise to the star’s surface and then cool, dim, and sink just a few hours later in a convective loop. This overturn causes small changes in the star’s brightness; how quickly it happens depends on how strongly the star’s gravity pulls material back into its depths.

In a young star, the flicker is rather weak and overshadowed by fluctuations in brightness due to starspots. These usually rotate in and out of view on timescales longer than eight hours. But as a star ages, its magnetic activity subsides, spots disappear, and the granulation flicker comes to the fore. As the star swells to become a red giant, the flicker strengthens dramatically. By observing a star’s brightness continuously — as the Kepler mission did — astronomers can measure its flicker. And by comparing to flicker measurements of stars with known surface gravities measured by asteroseismology,They are called “solar” panels or solar module because most of the time, the most powerful source of light available is the Sun. it is possible to determine the surface gravity from only the flicker measurements, the team reports in this week’s issue of Nature.A solar lamp is a portable light fixture composed of an LED lamp, a photovoltaic solar panel, and a rechargeable battery.

You can actually hear this process when the stellar light curves are converted into sound waves. In these representations from Nature Video, you can hear the high-frequency “hiss” of the flicker become louder as the star ages.

Europe rolls to Solheim

From the 45-foot putt that 17-year-old Charley Hull rolled in to re-ignite the momentum Sunday to the 4-foot tester Caroline Hedwall sank to end what little drama was left, the Europeans owned Colorado Golf Club.

Led by Hull, the youngest player to suit up at the Solheim Cup, and Hedwall, the first player to go 5-0 at this event, Europe romped to a record-setting 18-10 victory over the Americans and won the cup on U.S. soil for the first time since the event began in 1990.

”We took it to them,” Europe’s Suzann Pettersen said, ”and they couldn’t answer.”

This was a wire-to-wire victory, the likes of which very few saw coming.

America had more top-20 players (5 to 3), more major-title winners (5 to 3) and more Solheim Cup experience (25 years to 17) to say nothing of more success over the history of this team event (8 victories to 4).We offer solar photovoltaic system and commercial incentives to encourage our customers to install solar energy systems.

But Europe took the lead Friday, took an even firmer grasp of it with a sweep in the best-ball matches Saturday,We turn your dark into light courtesy of our brilliant sun, solar street light, solar power generation. then closed it out by winning five of 12 matches Sunday and earning half-points in five more.

A lightning delay of about an hour put off the inevitable, but when the weather cleared, Hedwall returned to the 17th tee box, tied with Michelle Wie, and didn’t miss a beat.

She halved that hole, then stuck her approach on 18 using a 9-iron from 150 yards out. She celebrated the putt that gave Europe its clinching 14th point with an uppercut into the air. A handful of her teammates, already off the course, ran to congratulate her.

A bit later, Catriona Matthew holed a 5-foot par putt to halve her match and give Europe the outright win on the seventh try in America. Within moments, the Europeans were in a full-throated rendition of ”We Are the Champions.”

This is the first time they’ve defended the cup, which they won two years ago in Ireland. Their eight-point victory was the largest in the history of the event.

”In sports you just cannot always predict what’s going to happen,” American Cristie Kerr said.

The course was hand-picked by the Americans and captain Meg Mallon brought her team to Colorado a handful of times in the months leading up to the tournament to get used to the undulations in the huge greens that are subtly influenced by the Rocky Mountains to the West. With wide,How solar panel cells work and where to buy solar kits for home use. almost-unmissable fairways, this was a three-day chipping and putting contest and the United States lost badly, especially in the closing stretches.

On Sunday alone, the U.S. saw leads turn into ties or losses over the final three holes in five matches.

”The way we played 16, 17 and 18 I think is really what made the difference,” Mallon said. ”It wasn’t for lack of preparation, because we played this golf course quite a bit. So it wasn’t like it was a surprise for us, it was just a matter of who dropped the putts on those holes and unfortunately it was the Europeans.”

European captain Liselotte Neumann said many of her players headed back onto the greens after their practice rounds earlier in the week to soak in the subtleties of the greens.

”We did talk a lot about the speed,” she said. ”As soon as we got here, we realized they were super-fast, some of the fastest we’ve ever played. It was a matter of reading the greens,Huge collection of solar outdoor light and garden lighting fixtures. reading the speed into the putts.”

American Paula Creamer went 1-3 for the week, including a 5-and-4 loss to Hull, who took the lead with a 45-foot birdie on No. 6 and never looked back. After Hull closed out the match on No. 14, she asked Creamer to autograph a golf ball for a friend back home.

”I’m going to take that as one of the highlights of my career right there,” Creamer said.Shop funtional and elegant solar lights, outdoor solar lighting, solar garden lights, path lights and decorative solar lights.

Kerr, another American veteran, went 1-2-1, earning the tie after she and Karine Icher agreed to halve the day’s final, meaningless match while walking up the 18th fairway in fading light.

Stacy Lewis, ranked second and fresh off a victory at the Women’s British Open, finished 1-2-1.

Mallon put her at the top of the lineup Sunday, knowing the Americans needed some quick, momentum-building wins to have any chance at a comeback from five points down. Lewis lost her lead when Anna Nordqvist, who had made a hole-in-one on No. 17 to close out a match a day earlier, hit her tee shot to 20 feet and made the putt. Lewis salvaged the tie by getting up and down on 18 after the last of a handful of shaky approach shots that marred her week on what Mallon called a ”second-shot course.”

While the U.S. veterans were struggling, Neumann got more than she ever could have expected from her six Solheim Cup rookies. They combined to go 12-5-2. That included a 3-0 effort from Spain’s Carlota Cigunda.

It was Cigunda at the center of the week’s biggest, and strangest, drama – on Friday, when she hit her second shot on No. 15 into a hazard, triggering a 25-minute delay while officials figured out where she should drop.

What Detroit Can Learn

Detroit’s declaration of bankruptcy has shed new light on the problems afflicting the city. Detroit’s population has dropped precipitously — from a height of 1.8 million in 1950 to 951,270 in 2000, to around 700,000 by 2013. Empty lots and abandoned buildings are a prominent sight around the city. Detroit is afflicted by poverty, with 36.2 per cent of residents living below the poverty line from 2007-2011, compared to 15.7 per cent for the state as a whole. Unemployment stood at 16 per cent in April 2013, while the state-wide rate was 8.4 per cent.

With high rates of poverty and a limited tax base, Detroit is challenged to raise revenues to maintain services, in education, public transit, garbage collection, police and fire. As an example, 40 per cent of the city’s streetlights do not work.

Where the City of Detroit, as per the 2010 US Census, consisted of 713,777 people, Detroit’s Metropolitan Statistical Area (MSA) had an overall population of 4,296,250. Across this MSA region, there are 207 municipal units,How solar panel cells work and where to buy solar kits for home use. including overlapping units such as counties. Municipal reform is hindered by the strong tradition of local control and autonomy in the United States and especially in the state of Michigan.We turn your dark into light courtesy of our brilliant sun, solar street light, solar power generation.

Former Labor Secretary and UC Berkeley professor Robert Reich illustrates the challenges of this decentralized and fragmented local government structure well in a post on his website, citing how Americans are increasingly segregated — geographically — by income. “Forty years ago,” writes Reich,Shop funtional and elegant solar lights, outdoor solar lighting, solar garden lights, path lights and decorative solar lights. “most cities (including Detroit) had a mixture of wealthy, middle-class, and poor residents. Now, each income group tends to live separately, in its own city, with its own tax bases.”

Reich further highlights that while Detroit is impoverished, many of its suburbs are among the most affluent in the country, with Oakland County being the fourth wealthiest county (of those with a million or more residents) in America. “Detroit,” Reich continues, “is a devastatingly poor, mostly black, increasingly abandoned island in the midst of a sea of comparative affluence that’s mostly white.”

This creates an environment where relatively affluent suburban municipalities have the tax-base to provide good quality public services, while the central city — Detroit — suffers. Municipalities like Dearborn and the Grosse Pointe municipalities geographically look like they were carved out of Detroit, to preserve (comparatively) more affluent tax-bases.

There are fundamental structural issues hindering Detroit, that helped precipitate its bankruptcy. In this context the Canadian example — where there is a greater tradition of provincial reorganization of local government structures, and where there have been more fundamental reforms, can be illustrative.

At the beginning of the 1960s, the province of New Brunswick was faced with glaring regional inequalities, where county governments were charged with providing a range of services from health, to social welfare, to justice, to education. Where affluent counties did well, poorer counties suffered under high taxes and poor quality services, with some counties unable to meet expenses and — in some cases — teetering close to bankruptcy.

In the 1960s, a progressive and reformist Liberal government, under Premier Louis Robichaud, carried out a fundamental restructuring of local government known as the program of Equal Opportunity. Services such as healthcare, education, justice, and social welfare were centralized at the provincial level,Huge collection of solar outdoor light and garden lighting fixtures. county governments were abolished as a redundant and overlapping level of government, and property tax assessment was centralized at the provincial level. Furthermore, a system of equalization payments was introduced to help more cash-strapped municipalities.

These reforms were controversial at the time, but were key in equalizing service provision and taxation across the province.

Another Canadian example is in Manitoba, where the Greater Winnipeg Area was amalgamated into one municipal entity in 1971 under another progressive and reformist government,We offer solar photovoltaic system and commercial incentives to encourage our customers to install solar energy systems. an NDP government led by Premier Ed Schreyer. Like with Equal Opportunity in New Brunswick, the aim of regional amalgamation was equalization of services and taxation, in this case between an inner-city which contained high rates of poverty, especially among Aboriginals who had moved to the city, and relatively affluent suburbs.

A 1972 document from the Government of Manitoba identified Winnipeg as both “a prime generator of economic life in the province” and “the greatest single repository of social ills within the province.” Hence, a goal to both better deal with poverty in the city while enhancing Winnipeg’s role as an economic engine for the province.

Neither system is perfect. In New Brunswick, municipal governments can often feel stifled from basic actions due to the province’s extensive oversight and, in Winnipeg, a common complaint is that suburban councillors outnumber inner-city ones thus dominating city council overall. However there is no denying that, even with shortcomings, both reforms were major improvements in equalization of service provision and fundraising ability.
