One out of 10 MP3 users will suffer hearing damages
December 16, 2009
The German philosopher Friedrich Nietzsche said: “Without music, life would be a mistake”. Apparently, a lot of people around the world agree. For example: 160 million people who own an iPod or other less “glamorous” music players. The European people love the music so much that, maybe, they are willing to sacrifice their hearing capacity to enjoy the music every day with these portable players. One out of 10 of these people will suffer irreversible hearing loss associated with the use of these gadgets, what could end up affecting the health of about 10 million people.
The EU’s scientific committee on emerging health risks has made a study on the consequences that could exist when people listen to music pumped into the ears above 89 decibels -which is the level at which noise will start to cause damage- by using portable players. The results were alarming. An EU safety standard currently restricts the noise level of personal music players to 100 dB, and usually most of the users listen loud music to overcome other noises of the city.
This way, the current priority for the European committee is to find technical alternatives to minimize the hearing damage in people who live in Europe. Also, a proposal to lower the EU legal limit of 100 decibels for MP3 players is being studied.
The European scientists have established that between 5% and 10% of the MP3 users in Europe (between 2,5 and 10 million people), could be at risk of hearing damage from heavy use of MP3 players. At this time, it is calculated that between 50 and 100 million people use MP3 players or other type of music players every day in Europe.

A common bacteria in the pond can be made of fuel cell power generation
U.S. scientists found that in fresh water pond in a common bacteria can be used for power generation. This bacteria can break down organic pollutants, but also a variety of harsh environment resistance.
U.S. Medical University of South Carolina Charles Millikan toshiba satellite l203 battery, toshiba satellite l205 battery, held in Atlanta on the 7th of the American Society for Microbiology annual meeting reported that the concept of using bacteria to generate electricity is not new, there are a number of research group engaged in the development of microbial fuel cell, but They found the two apart: first, generating strains of bacteria belonging to the family desulfurization, this family of bacteria in the freshwater environment is widespread, and has been used to eliminate the human content of the organic pollutants; followed by the adverse external environment, or lack of nutrients, the spores can be turned into a desulfurization strain state, and the spores to high temperature, strong radiation and other harsh environment to survive, once the environment can grow into normal strains.
Millikan’s experiment and others show that the bacteria made fuel cell, as long as there is sufficient organic matter as a “food source”, the battery of bacterial decomposition of food can be sustained through the release of charged particles. The researchers said that this bacterial decomposition of organic pollutants, while power generation, has the double benefit. In their view, the results of the field of micro-organisms generating a big step forward.

Brazil and Japan use of alcohol fuel
Automotive pollution control: the use of alcohol fuels Brazil and Japan, the United States and the European Union to promote new products, the introduction of new technology. Abandoned cars in many places it is difficult to deal with, and they cause serious environmental pollution problems dell inspiron 1150 battery,.
Gas emissions from cars are an important flow of pollution sources, vehicle exhaust gas pollution in large cities, one of the main gas. To address the issue of mobile pollution sources, to be used in a wide range of technical measures:
(1) the use of emission control technology. For example, improvements in vehicle engines, the use of thin mixed gas, the exhaust re-combustion of exhaust gas catalyst reaction such as the use of three, can reduce emissions of nitrogen oxides.
(2) to improve vehicle fuel. Taiwan from January 1990, all newly manufactured cars, are the use of lead-free cars, new cars to install catalytic converters, to 1995, lead and other gases decreased pollution. South Korea began in 1993 the application of carcinogens and other pollutants by half the number of low-pollution gasoline to reduce air pollution.
(3) the application of a new type of fuel. Alcohol such as gasoline, methanol, hydrogen and other fuels for vehicles. Full combustion of these fuels can greatly reduce the intensity of environmental pollution.
The first application of the Brazilian sugar cane bagasse fermentation enzyme engineering preparation of fuel alcohol, according to the proportion of alcohol and gasoline as a fuel compatibility. 90 years, most of the cars in Brazil used this mixed fuel. Germany, this alcohol fuel gasoline vehicles, a variety of climatic conditions in the safe driving. Japan also is developing ethanol engine, with a view to the full use of alcohol to replace gasoline as fuel. In 1990 compaq evo n600 battery, Japan’s major cities are beginning to see the car as fuel drunk.
Car engine started, in the first few minutes of untreated discharges of pollutants, because inhibition of pollutants has not yet been heated catalytic converters to work state. Must be controlled to improve the air pollutants emitted from the first. To address this problem, the United States and precision combustion格雷格雷斯companies carried out a number of catalytic converters to installation of electric pre-heater, so that emissions of the first rapid increase in gas temperature. Using electricity to heat the gas with the metal gate is made of extruded metal powder. Followed by the emission of gases out through a ceramic substrate turn them into non-toxic gas. This latest product from Corning Inc., the prototype device is installed near the engine exhaust system. In a recent lab test, the device easy to reach California in 1997 for products developed by the strict rules. Corning’s catalytic converter from a non-alkanes and carbon monoxide gas in California is less than half the limit in 1997. The device plus a metal gate that is, matrix layer, so that gas from entering the converter when the engine temperature.The energy of the substrate from a battery pack, it is not such a problem exists, namely: to enable the rapid temperature rise purifiers need a separate battery pack, or else the car needs a larger battery pack, which would increased vehicle weight and increase in vehicle costs.
Access to the European atmosphere of nitric oxide, 42% were caused by motor vehicles. Car is also dirty hydrocarbon emissions and carbon monoxide. In 1992, the European Community within the framework of all new cars equipped with catalytic converters, such as the type of new technology products in order to reduce the emissions of these pollutants. On the other hand, Volkswagen developed a new turbocharged diesel engine, fuel consumption than the traditional spark ignition engine to save 30% less carbon monoxide emissions by 20%. The use of such diesel engines than gasoline engines to clean money.
Volkswagen and the first to study the Bavarian Motor Company’s car and then use a revolutionary technology, the hope that dumps the thing of the past field history. A pilot plant in Lille, in the trial on a number of Volkswagen Parts of plastics and glass, paint and other re-use. Volkswagen built a cost of one billion marks in 1993 to start a new public paint, completely doing away with chemical solvents, to water-based paint, which will significantly reduce pollution. Bavarian companies, the use of “removable design” new technology aimed at simplifying the parts and materials, so easy to disassemble and reuse car. Bavarian Car two-seater body d5318 battery, u4873 battery ZI all plastic manufacturers, as long as 20 to 30 minutes removed from the metal frame.
Excessive pollution has been measured a number of countries included in the scope of traffic management, Environmental Protection Agency that it is no longer a thing, but as a common action of society as a whole.
