Silicone oil to reflect radiation: Find a way "revolutionary" to treat cancer of the eye without losing vision
Find a way "revolutionary" to treat cancer of the eye without losing vision
http://thechemistrysideoftheforce.blogspot.com/
* The required eye cancer radiation treatment that causes permanent blindness in half of patients who receive it.
* Injecting silicone oil into the eye can block up to 55% of harmful radiation and prevent blindness.
* This type of cancer can develop in people of any age.
Eye Study
Rare and devastating eye cancer requires radiation treatment that causes permanent blindness in half of patients who receive it. However, assistant professor of the Faculty of Medicine of the University of Colorado (USA) Scott Oliver has discovered a new method that could avoid this serious side effect.
In a study published in the journal Archives of Ophthalmology, Oliver describes how injecting silicone oil into the eye can block up to 55% of harmful radiation used to treat cancer and prevent blindness in most patients .
Oliver focused on the study of uveal melanoma, the most common and dangerous form of eye cancer that affects about 2,000 people each year worldwide. This tumor can spread rapidly to the liver and lungs, making it lethal.
This type of cancer may develop in people of all ages. The white skin and excessive sun exposure tend to be the main triggers. In recent years, oncologists have begun to use the introduction of brachytherapy, radioactive seeds into the eye-to cure this disease.
However, radiation therapy remains the most common form of treatment for this eye cancer as a treatment of a single week burn the tumor is achieved, albeit with serious long-term. "The radiation damages the blood vessels and nerves in the back of the eye, resulting in that, for the three years, more than half of the patients is blind," says the study.
Silicone oil to reflect radiation
In this regard, silicone oil, commonly used to treat retinal detachment, may reflect the majority of this radiation, preventing ocular cell death. According to this expert says, "one does not reflect more of radiation because the back of the eye is able to tolerate it in small doses."
Oliver saw the effects of this oil and animal corpses and says his next goal is to "steer the project to a clinical study in humans." "So far the eye could be saved with radiation, but the vision remained at only half the cases. With this treatment can make things much better in the future," he says.

Algum tempo atrás nós falamos sobre a rodovia para carros elétricos, bem, parece que a Mitsubishi criou uma solução mais flexível,
É portátil estações de recarga para carros elétricos da rede, assim parece complicado, mas basicamente são "fornecedores" de eletricidade que pode ser colocado em qualquer lugar e estão ligados entre si.
Ao contrário das estações de costume, que recebem, graças a sensores colocados nos veículos para controlar os níveis de energia do mesmo, assim que são colocados nos pontos onde eles são necessários.
Segundo seu criador, Zafer Sahinoglu Mitsubishi Electric Research Laboratories, em Cambridge, com apenas 5 estações, podem ser abrangidos 100 carros elétricos em um trecho de 100 quilômetros da rodovia.
Pessoalmente, penso que com o custo de um quilômetro da rodovia, não é um lugar ruim um sistema que utiliza a infra-estrutura. E que nem sempre produzem o seu próprio raios e recarregar a Back to the Future.

A baby lives with silicone ear. | Enlarge image
Madison, aged five, was born in the U.S. and already has two ears.
Jennifer was born in the U.S. with a congenital problem called '"microtia" and that affects the normal development of one ear, which is usually right.
This small, however, has been very lucky to find Robert Barron, a former CIA agent, a specialist in disguise to be other spies seeking to fulfill their secret missions.
This expert's ear Madison rebuilt from the mold and made another one identical.
Some of his views, identical to the originals, are attached to the body with glue, while others carry a more complicated and require assembly titanium screws embedded in bone, eye socket as he did.

Gastric balloon for weight reduction
http://thechemistrysideoftheforce.blogspot.com/
Gastric balloon for weight reduction. The gastric balloon is a method to help weight loss in people with morbid obesity. The ball is soft, flexible silicone, is implanted in the patient's stomach endoscopically.
The procedure is simple, there is no need for surgery and the same simple way is removed. It is designed to fill a place in the stomach, reducing the food in place for patients.
It gets fairly rapid weight loss, although the patient must commit to following a course of re-education of eating habits.

In the future, the second car of the family will be a electric car
For Luis Padial, member of the Cabinet Secretariat of State for Energy, the electric vehicle will bring great benefits. Among them, solve the energy dependency of Spain, help diversify the power generation and enhance the indigenous production. In addition, in 2020 to absorb 10% of electricity supply. But "to this day, the electric vehicle is not for the heat," he said. Much remains to be done to stimulate demand, which can be achieved with the increase of charging points, more information on this and favoring the use of environmentally friendly car from local authorities. On the problem of the batteries, the bottle is half full. "There is room for research in the medium term," said Padial aware that "electric vehicles represent an opportunity from the standpoint of industry and technology." http://thechemistrysideoftheforce.blogspot.com/
A shared vision of sectoral policies deputy director of Industry, Timoteo de la Fuente. Some automotive brands and develop hybrid and electric vehicles, which means to be making inroads. But despite being much more efficient than internal combustion engine, the energy use of an electric vehicle engine is around 70%, while the combustion is 17% - the burden of their lack of autonomy makes the car Power does not come off second vehicle profile restricted to urban use.
The experts recalled that the population is concentrated in the cities and the needs of drivers in the city, 50% traveled less than 20 miles a day, fit into the range of 150 kilometers. "It would suffice to charge once a week," says de la Fuente. "The goal is to have 350 000 recharging points in 2014, and a million electric vehicles (250,000 electric and 750,000 hybrids), but today there are 24 million cars on the street," he said.
A low demand and high price [around 30,000 euros] joined other technological challenges that will affect the future of mobility, such as the manufacture of batteries. Although the EU looks to electric car in his plans to promote clean energy, we will continue improving the efficiency of the combustion engine, while the electric vehicle is developed long term, as stated by the Deputy Head of Unit address general mobility and transport in the EU, Franz Soldner.

Apple has suffered a kind of evil eye with iPhone 4, as the accumulation of nonsense associated with its new terminal seems to be endless.
| Someone might start thinking that Apple has suffered a kind of evil eye with iPhone 4, as the accumulation of nonsense associated with its new terminal seems to be endless. Curious is as well that all this would not affect their sales. Now it is the turn of the Bumpers, silicone protectors that Apple gives to all owners of iPhone in April, to solve the problem of loss of coverage. It turns out that many iPhone users are sending four complaints to Apple Bumpers related scratches. Removing the bumper to clean the phone many users have noticed your phone scratched at the ends. http://thechemistrysideoftheforce.blogspot.com/ The story with the Bumpers does not end there, because for Nick Bilton, one of the editors of The New York Times, these silicone sleeves are not very effective. He himself proved when he recently accidentally your iPhone in April fell to the ground and saw its screen is cracked on all sides. This has two obvious explanations, the first is that although the Bumper translation is something like "bumper" not protected enough and falls lottery may ruin our phone in a second. The second explanation is that the new iPhone screen 4 is a priori much more resilient than previously employed polycarbonate. However, it is stronger if we talk about scratches, because when the four broken iPhone screen, it is in pieces and in different areas, that when the polycarbonate lie fell, suffered a small cut into the glass. So be very careful in thinking that the bumper is a bulletproof vest for our iPhone in April, be careful with the terminal fall seems more fragile than we were told. So far Apple has not made any statement regarding the Bumpers.  |

quimica - chemistry: The Coda Automotive all-electric sedan
the handful of electric vehicles that FedEx is testing are wonderful, offering sufficient range and one-third the operating cost. 
But because an electric truck costs three or four times more than a conventional truck, FedEx's worldwide fleet of all-electrics is only 19 out of about 40,000 trucks.
"We want those trucks. We believe in energy independence," said Jackson, vice president of FedEx environmental affairs and sustainability. "We have a deep belief in electrification, but the capital (needed) has inhibited us to what we have now."
So it goes for so many consumers and businesses considering electric vehicles. The smooth and peppy acceleration of electric motors makes for a good driving experience, fueling up is cheaper, and owning a plug-in reduces imported oil and carbon emissions.
But for electric vehicles to break out beyond early technology adapters, battery prices need to fall dramatically--to about half where they are today in the coming years--said auto executives at the Fortune Brainstorm Green conference here. Cost reductions are expected to come from higher scale manufacturing and technology improvements.
"By mid-decade I have high confidence that we (as an industry) will establish (battery) cell production in the U.S.," said Tony Posawatz, the vehicle line director for the Chevy Volt. "The simple fact of producing cells with shorter transport takes likely hundreds of dollars out of the cost of pack."
Overall, the sentiment at the conference is that electric vehicles, although still not a mass-market product, are going to make a commercial impact. The question is how quickly cost reductions can spur sales, with some more confident than others.
"Within a very short period of time, we can get to parity with gasoline vehicles on the curve we've seen (of battery improvements) over the last 10 years," said Li Lu, one of the investors in BYD, a Chinese company that plans to bring an electric sedan to the U.S. "There will be a time that people will say, 'Why do we bother with gasoline cars?'"
Warren Buffett, chairman of Berkshire Hathaway, is one of the investors in BYD, which has been manufacturing batteries for electronics for years. BYD, which is testing electric taxis in China, is said to have developed a car with a 200-mile range.
Too much attention for EVs?
One of the main drivers for electric vehicles is the lower emissions they promise as compared with gasoline engines. By making power generation cleaner, there is the potential to reduce carbon dioxide emissions from autos by 75 percent by going electric, said David Sokol, who is chairman of Berkshire unit MidAmerican Energy Holdings and is considered a likely successor to Buffett at Berkshire Hathaway.
But not everyone believes that electric vehicles deserve all the attention they get, particularly when it comes to government incentives and subsidies. Vinod Khosla, who is perhaps the most high-profile green-tech investor, is putting money into biofuels and improvements to the internal combustion engine, which could become 30 percent to 50 percent more efficient.
"I believe (biofuels) is the single most economic way to get to low-carbon transportation," he said at the conference. "All this focus on fundamentally uneconomic batteries has reduced investor interest in improving the internal combustion engine."
FedEx is testing these delivery cabs in Paris. They are pedal-powered but assisted by an electric motor.
(Credit: Martin LaMonica/CNET)Because of the higher costs of hybrids and electric vehicles, they are unlikely to meet the so-called "China price," or be affordable enough for consumers in India and China, where the bulk of new cars sales will be in the next 20 years.
In the U.S., automakers are testing their cars to find what works and doesn't with customers. BMW for the past several months has been testing the Mini-E with customer and found that the 100-mile range is sufficient for most drivers, but that the task of installing charging stations needs to be streamlined significantly, said Tom Baloga, vice president of engineering for BMW North America.
Nissan will start taking orders for the all-electric Leaf later this month and General Motors has started manufacturing battery packs for the Volt, which will go on sale later this year. The Leaf will cost $33,000 before state and federal incentives.
Start-up Coda Automotive will begin selling an electric sedan with a slightly longer range than the Leaf in California later this year. Coda's sedan will cost around $35,000 after state and federal subsidies. When cost of fuel is considered into the equation, the Coda sedan is the equivalent of buying a compact that costs just less than $30,000, according to Coda CEO Kevin Czinger.
"When talking to potential customers, we have to be transparent about whether the car is for them," said Czinger. Coda plans to have applications that consumers to fill out to calculate daily driving and monthly fuel costs. "We want it to be priced for everyday people and for everyday use."
The Coda Automotive all-electric sedan, which is set for release in the fourth quarter, can go about 100 miles on a charge and will cost about $35,000 after subsidies.

Endesa prevee poner puntos de recarga eléctrica en los parkings de los centros comerciales
http://thechemistrysideoftheforce.blogspot.com/ 
Los coches eléctricos cada vez tienen más presencia en las ciudades, lo que abre un nuevo mercado para las compañías eléctricas, ya que estos automóviles -que se abastecen con electricidad en lugar de gasolina- necesitan de unos postes de recarga para su funcionamiento. En esta línea está trabajando Endesa, que ya cuenta con estos puntos llamados electrolineras en ciudades como Madrid, Valencia y Sevilla y que ahora está estudiando instalar en Córdoba en los aparcamientos públicos. El director de Endesa en la provincia, Alfredo Rodríguez, aseguró que la compañía "está al servicio de todos los ayuntamientos que los soliciten" y, aunque el Consistorio cordobés todavía no ha hecho ninguna propuesta, la idea de Endesa es presentar su propio proyecto al igual que ha hecho en otras ciudades españolas. La explotación de estos puntos -que se conocen como electrolineras- no tiene por qué recaer en Endesa ya que la liberalización del mercado permite ahora elegir la compañía. En este sentido, Rodríguez apuntó que la idea de la eléctrica que representa es hacerse cargo de los puntos de recarga en Córdoba, pero que el Ayuntamiento tendrá la última palabra.
En caso de prosperar la propuesta, los aparcamientos que podrían contar con este sistema serían el ubicado en la avenida de la Victoria, los del Vial Norte o el parking de Puerta Sevilla. Según los datos facilitados por las empresas automovilísticas especializadas en este tipo de motor, en Córdoba hay aproximadamente unos 300 coches híbridos, que necesitarían de estas recargas. Además, es la provincia española con mayor flota de taxis de este tipo, ya que aproximadamente el 10% del parque público cuenta con estos motores. Una de las grandes ventajas de los híbridos es que permiten aprovechar un 30% de la energía que generan, mientras que un vehículo convencional de gasolina tan sólo utiliza un 19%. Esta mejora de la eficiencia se consigue gracias a las baterías, que almacenan energía que en los sistemas convencionales de propulsión se pierde.
La implantación de los postes de recarga es una realidad en grandes ciudades como Barcelona, donde habrá 400 puntos a finales del año que viene, o en Valencia, donde hay contabilizados un centenar. La intención de El Corte Inglés, por ejemplo, es incluir un poste de recarga gratuito en los parking de todos su centros comerciales y en los establecimientos de El Ejido (Almería) o en Murcia ya es una realidad. Además de Endesa, Iberdrola Repsol, ACS, FCC o Acciona están tomando posiciones y preparando alianzas para abordar experiencias pilotos en esta primera fase. En Málaga, Endesa junto a otro grupo de instituciones lidera un proyecto único en España que tiene como objetivo precisamente estudiar fórmulas para reducir el consumo eléctrico.
