Women : No Sex For Facebook

Women : No Sex For Facebook

CALIFORNIA - A recent survey revealed that 20 percent of women are not willing to have sex for the sake of Facebook.

As quoted from Digital Trends, , in a Cosmopolitan magazine survey involving two thousand women revealed that one in five women are not willing to have sex for a week, rather than deciding their access to Facebook.

Cosmopolitan magazine survey is more detailed explained that approximately 57 percent of women prefer the Internet to play on PC for a week, rather than have sex. Then 50 percent of respondents said that they preferred 'up-ness' through cell phones than sex.

Even so, approximately 80 percent of respondents would gladly cut off access to television for a week, and 70 percent are willing to stop the SMS for one week, and still have sex.

The results of this study indicate that the current social networking sites and internet has been a big part of people's lives around the world.

Second Generation Biofuels Discovered

Meeting of the Parties to the 16th Conference on Global Climate Change in Cancun, Mexico, said Brazilian President Luiz Inacio Lula da Silva will not make important decisions. This is due to the absence of strong state leaders in attendance to carry the various ways to become an important and binding decisions.

Meeting of the Parties (COP) to the 16th at the United Nations Framework Convention on Climate Change (UNFCCC) held in Cancun on 29 November to 10 December 2010.

Lula's statement quoted by various media world. This is thanks to the success of Brazil to develop biofuels production or biofuels to mitigate global warming since the 1970s.

Brazil in 2007 was recorded producing 5958 million gallons, or 22,653 million liters of bioethanol. The success of Brazil was ranked second after the United States (6488 million gallons).

Brazil biofuels processing with sugar cane and corn feedstock. For Brazil, there is an important decision or not of an international forum in Cancun which was attended by more than 190 countries still continue efforts to produce environmentally friendly fuels such.

The second generation
How is Indonesia?
The production of biofuels can not say how or fail when using a raw material oil, corn, or sugar cane. This is due to compete with food needs.

Production of biofuels with castor oil feedstock to avoid competition with food needs sought. However, the same does not work.

Recently Deputy Head of Agency for the Assessment and Application of Technology (BPPT) Field of Information Technology, Energy, and Materials Unggul Priyanto promoting second generation biofuels production issues, namely the generation of technology that leaves raw materials that compete with food.

"Raw materials of biomass residues that are now abundant in number," said Superior.
Starch Technology Center BPPT in Lampung has researched the processing of biofuels by feedstock oil palm empty fruit bunches. Indonesia is estimated to have 12.9 million tonnes of oil palm empty fruit bunches per year.

"The price of biofuels is still not able to compete with fossil fuels," said Superior.
Head of Starch Technology Center BPPT Agus Eko Cahyono said, to produce 1 liter of biofuel takes about 5 kilograms of oil palm empty fruit bunches. Production price reached $1 per liter.

"That makes the price of biofuels from waste oil is still expensive, which is still high prices of the enzyme. However, the trend is predicted to decline, "said Agus.

Price of oil palm empty fruit bunches, according to Agus, calculated at 5cent per kilograms.

Superior says, biomass residues from agricultural and industrial estates are very abundant. However, its use as raw material for biofuels is still very minimal.

"So far, almost no or very young use to produce biofuels," said Superior.
According to Superior, Indonesia is estimated to annually produce residue from sugarcane processing industry in the form of the waste reached 8.5 million tons. Sugarcane leaf litter produced reached 1.29 million tons.

From the oil palm plantation sector, acquired each year 3.45 million tons of oil cake. Then the wood fiber plantations reached 6.7 million tons.

Residues in the form of empty fruit bunches of oil palm reaches a high enough number, reaching 12.9 million tons. Then the residue of the oil processing industry reached 31 million tons. "Biomass residues that are compounded from agriculture and timber," said Superior.

Production of rice, each year it can be obtained residue reaches 12.5 million tons. From the wood processing residues are 8.345 million tons.

How abundant biomass residues for second generation biofuels. Currently the price of second-generation biofuels production is higher than the price of fossil fuel.

Brazil, which process raw materials of corn or sugarcane to biofuels, experiencing the same constraints. Production value is easily understood in terms of production value of raw material so that the price of biofuels in Brazil is still higher than fossil fuel.

Supposedly this is different for second generation biofuels. Residual biomass feedstock is relatively inexpensive, often even become valueless waste and simply thrown away.
Second generation biofuels should be cheaper. That's the hope.

Special Materials Research and Cost Cheap Preferred Choice

Special Materials Research and Cost Cheap Preferred Choice

Indication of the government increased funding for future research has yet to be seen. Low research activities funds are made from cheap, but bring substantial benefits to society, are preferred.

"Now, scientists, research institutes, and universities should be responsible for sorting out research on a limited budget but made from cheaper and provide maximum benefit to the community," said astronomer from Bandung Institute of Technology, Bambang Hidayat (76), as speakers Guests on the surrender of the 17th Science and Technology Award by the Indonesia Toray Science Foundation (ITSF) in Jakarta, Thursday (10 / 2).

ITSF established companies from Japan. The award is accompanied by research funds of $2500 awarded to nine teachers at the high school level science education. Among the Cece Sutia proposing research the title "Use of Kitchen Equipment and Materials to Demonstrate Scientific Principles in Science".

Grant funds research around $3500 up to $4000 awarded to 15 researchers from various universities and research institutes. The highest award is accompanied Rp 75 million in research funding awarded to Suryadi Ismadji of Widya Mandala Catholic University Surabaya.

Suryadi research proposal titled "Cheap and Utilization of Agricultural Waste Materials for Environmental Management and Other Materials Conversion Has Become The Economist".
"One of them, research it wants to make leather waste cassava (cassava) for activated carbon as a material superkapasitor," said Suryadi.
Superkapasitor required as an element of making storage batteries or electric current. Sawn wood waste and waste distances are also mentioned as an inexpensive material that can be optimized benefits for energy sources.
"This research completely utilize existing resources in the surrounding community so that findings can be applied to communities with innovative raw materials are cheap and available as an abundant agricultural waste," said Suryadi.

Found How To Make Fuel From Vegetable Oil Seed Generator

Found How To Make Fuel From Vegetable Oil Seed Generator

Bintaro tree (Cerbera manghas) is often only used as a mere plant perindang road. Apparently this plant is good also functioned as a drag abrasion resistant to sea because of high salinity. In addition, seeds can be used as biofuels, for example for generator fuel.
This technology specifically for remote areas (remote areas), "said Dr. Ir Desrial MEng, Chairman, Department of Mechanical Engineering and Faculty of Agricultural Technology Biosistem at Bogor Agricultural University (IPB), in Bogor, West Java.
Remote areas more specifically, according to Desrial, coastal areas are susceptible to abrasion. Areas that can be a small coastal islands and beaches are also a large island.
Many causes damage to coastal ecosystems. Policy over the function of lowland forest to oil palm plantation concessions could be the cause.
In most of the lowland forests are also peatlands. According Desrial, bintaro tree can grow too well in peatlands.
As in the Jambi and Riau communities, coastal peatlands in many participating converted for oil palm cultivation. Some land was also lost eroded abrasion.
"Trees bintaro for coastal conservation as well as the seeds contain oil that can be used for substitution of diesel fuel," said Desrial.
Bintaro raw fruits bright green. According Desrial, in the fruit raw bintaro no cyanide toxicity, but easily lost unless exposed to sunlight.
"Use the old fruit bintaro brownish to take oil from the seeds," said Desrial.
Utilization of fruit bintaro parents can avoid the addition of cyanide poisoning while peeling at once to get the optimum content of vegetable oils. Bintaro oil making process that involves stripping, taking seeds, dried beans, and seeds extracted.
"Ekstrasinya the compression process, ie given a certain pressure and temperature so that the liquid oil out of seeds," said Desrial.
Liquid as crude oil bintaro. The content of the sap is still high.
To eliminate the sap in the oil, taken by degumming process (removal of gum / sap) is simple. Typically used the addition of phosphate to bind and precipitate thus obtained resin bintaro pure oil.
To obtain 1 kilogram of oil it takes 2.9 pounds of pure bintaro bintaro seeds. Bintaro seed as much as it can be obtained from the 36.4 kilograms of fruit bintaro old.
"One tree can produce bintaro optimally bintaro 300 kilograms of fruit annually," said Desrial.
Special converter
Research bintaro fruit to produce diesel oil substitution was started in 2010. Research aimed at people in the Gulf region Meranti, Riau, which have a source of raw materials bintaro relatively abundant.
According Desrial, research originally intended to replace kerosene, but the quality of the oil was almost equivalent bintaro pure diesel.
"Oil bintaro ultimately intended for oil generators, electric generating machinery," said Desrial.
Desrial also designing generators with fuel oil bintaro pure. He added a special converter that contains a heating element can be controlled by an energy source in the form of 12-volt battery.
"A special converter to increase the oil temperature to 70 degrees Celsius bintaro making it easier for combustion in the gensets," said Desrial.

For the initial lighter diesel generators are still used. The use of diesel is also at a late stage to avoid condensation in the channel bintaro oil genset system is turned off when wanted.
Bintaro oil use will help the areas difficult to reach the distribution of diesel fuel. At least, planting bintaro on the beach can also save the environment in order to avoid abrasion.

Germany Launches Super Stealth Submarine First Hydrogen Fueled

Germany Launches Super Stealth Submarine First Hydrogen Fueled

The new German-made submarines U-212 A was almost no noise. Also emit almost no heat radiation and is completely made of nonmagnetic metal.

Although sophisticated submarine is not a nuclear submarine, but also not a diesel submarine. U-212 A is the most advanced submarines in the world because it uses a hydrogen fuel cell developed by German naval shipyard Howaldtswerke Deutsche Werft, which claims that a "top German submarine technology."

Super-stealth ship is the first of its kind to be powered by a revolutionary hydrogen fuel cells that enable it cruises without noise or exhaust heat.

That's important, because, according to Bernd Arjes, a captain in the German Navy. "We operate in coastal waters around Europe and submarines are designed specifically to locate submarines. If you want to find other submarines of course you should not speak out, "he said. With the latest technology, he adds, "The submarine is virtually undetectable."

U-212 A is not like conventional submarines, which need air to burn diesel fuel, fuel cell does not require oxygen to operate.

This means it can remain submerged for weeks - hold my breath many times longer than a cousin who drank diesel submarines.

As a hitter submarine submarines armed with 12 heavyweight torpedo that is guided, each capable of destroying a warship or off an aircraft carrier.

"A carrier may not be tampered with one torpedo but maybe on the wheel or something then the carrier may not be bermanuverdan to use the aircraft," said Arjes.

Germany, which has no nuclear weapons or nuclear-powered ship itself, is the world's third largest exporter of defense goods.

Export Edition has been sold to the navy of Greece, Portugal and South Korea. With automatic device, requiring only minor submarine crew hence there is little comfort for those on board. Even so the life of submariners still remains one of the limited residence
