what's the view of nanotechnology in public point

"As technologies converge in the 21 st century, humanity finally reaches them, a state of world peace, universal prosperity and progress to a higher level of compassion and service."

They are strong words on the official acer as07a51 battery website of the United States in June 2002 launched a comprehensive interdisciplinary, full of federal funds. This is known as the convergence of technologies, but is better known by the acronym NBIC, which means that the convergence between nanotechnology, biotechnology, information technology and cognitive science [63]. This is the first of the four groups of science and technology, nanotechnology, which is the spearhead.

The famous American physicist Richard Feynman, who could be the father of the project on nanotechnology at the conference will be: "There is plenty of room below," in 1959 at the California Institute of Dell XPS M1330 battery Technology, Feynman [64] described, that they imagined believe to be available soon on the manipulation of matter on a human scale of the molecule, atom by atom-operation. The configuration of the nanoscale has been created for life.

With the famous "nano world" engineering works now in nanometers (one billionth of a meter), the elements certainly very small in relation to objects of everyday life (for example, 30 000 times smaller than a human hair), but much larger of the objects observed large particle accelerators. The increased SONY VGP-BPS13 battery capacity for the production and manipulation of objects microns (millionths of a meter) in nanometers, opening up prospects very unique among major potential applications.

Prior to publication, and identify applications and ethical issues associated with this approach, we wonder about the specificity of this scientific field, which is often presented as radically new. These are actually two modes of operation after the nano-world, which today represent a true innovation:

A first method is to functions "milli" or "micro" to reduce to the nanoscale, which is often cited example, computer chips, whose size is always the result of improved production technology of silicon reduced.

Another method is to go from very small to small. These are procedures that atoms and molecules to create new complex nanosystems to manipulate nature. This SONY VGP-BPS2 battery approach can be made visible to a millionth of a millimeter through the creation and development of tools and the manipulation of matter on this scale. This method is based on the creation of new tools: atomic force microscopes through tunnels, the electronic optical tweezers to manipulate high-resolution or matter atom by atom.

Finally, dell inspiron 1300 battery nanotechnology opens up new opportunities created by other generic technologies, such as biotechnology and information technologies converge with cognitive science. As such, these new applications of nanotechnology, particularly in the field of medical informatics and new materials with new services. Political economy, note that the complexity of the development of nanotechnology, and use only by tech-heavy industrial structures, a further Dell Inspiron Mini 12 battery increase in the concentration of large industrial groups, particularly patents.

Nanotechnology is undoubtedly one of the wave technology, such as synthetic biology, will determine our future.

I. application areas of nanotechnology

The focus of applications that can run are:

In health, many areas could be brought to current and future situation in the field of medicine, in particular diagnostic and therapeutic tools, are affected more applications both in vitro and in vivo are possible:

The behavior of the functional markers of non-invasive imaging (nontraumatic)

Design of new drugs that contain nanomaterials and nanosystems,

The administration of drugs and of new pharmacological doses appear to be less toxic to his favorite target.

In the food sector, in the absence of mandatory labeling of a public debate and without rules, products with nanotechnology in the process of "contamination" of the food chain. These nanoparticles, nanocapsules and nano-emulsions in agricultural pesticides in food packaging and food materials, food and storage containers. The Friends of the Earth has identified 106 of these products today, but it seems certain that this is only a small proportion of Asus Eee PC battery marketed products.

However, there is no specific regulation for nanotechnology, and no proof is necessary first of nanomaterials in food packaging and agricultural products are used.

In general, nanotechnology is also threatening the sustainable development of agriculture and nutrition. It is feared that could improve the control of the agricultural and food systems of large corporations. This would lead to a reduction of the SONY battery VGP-BPL13 power of farmers for on-site food production, as in the case of GMOs.

Other areas

Cosmetics:

For several years the cosmetic industry uses nanotechnology and nanomaterials in their products. Because of their small size, nanomaterials are able to develop new physical and chemical properties. Nanoscale components Dell XPS M1530 battery(organic nanoparticles, metal oxides TiO2 and ZnO) may also invest in other formulations of cosmetics, creams, powders, perfumes, shampoos, nail polish, lipstick, toothpaste, etc. are installed.

As the mention of nanomaterials in the labeling is not required, to this day is very difficult to be an exhaustive list of cosmetic products that contain them. According to the Institute of Woodrow Wilson, the identified products containing nanomaterials, there was a quarantine in the cosmetics market, the nanoparticles may be present.

Packing:

Nanomaterials can also be incorporated in packaging to act on the traceability of conservation, recycling and eating. These nano-chips embedded in the Dell Vostro A840 battery package can follow the evolution of food microbiology in their lives and contribute to their health surveillance. Deposit in the nanolayers film can protect against moisture.

Other materials:

Microstructures in new materials have been developed. At this scale can alter the physical and chemical properties of materials. For example, carbon nanotubes sets of carbon atoms in the form of tubes with a diameter of 200-100 nanometers and a length of one micron. Very lightweight and shock resistant, while being very flexible, which can behave like a metal, but also as a semiconductor. They have something mechanical, optical or chemical special. This material is thus a hundred times stronger and six times lighter than steel and Dell Studio 1735 battery has a thermal conductivity comparable to diamond.

New types of fabrics, paintings, self-cleaning window coatings, wear-resistant solar cells and electronic components, products are available on the market.

Finally, about 2000 nanoparticles are already commercially available and there is a presence in more than 600 products. Nanomaterials in consumer products covered are usually organized in a matrix or solid or liquid.

Health Hazards II identified

In this new area, many health risks can develop. The main Toshiba PA3399U-1BRS battery objectives are the application and release of the product during manufacture, use or disposal, the nanoparticles can (summary of the different atoms or chemical compounds). Because of their small size nanoparticles can reach the smallest structures of the lungs, called alveoli. This is where you can breath gas exchange between the air that we and the blood. You can have the effect of nanoparticles in this vital system, are still poorly understood. They seem to be inflammatory reactions,Toshiba PA3465U-1BRS battery and also changes in the lung tissue similar to silicosis (a disease caused by exposure to silica dust) or asbestosis (asbestos) due, followed by the particle causes of this material. Current knowledge on the subject, obtained from animal studies, which cover a very small number of nanoparticles (eg, carbon and titanium oxide). Studies in cell cultures have shown that nanoparticles can be absorbed easily and can, depending on their chemical composition, without adverse effects on these cells. HP Pavilion DV5000 battery Studies are also in the absorption of nanoparticles through the skin for the day done, the knowledge gained in this area be excluded a priori the absorption of healthy skin. Other studies have shown that nanoparticles of polystyrene and titanium oxide has been through the digestive tract and then won the liver.

III. Ethical issues

These new applications are many ethical issues.

These include:

The issue of traceability: when the nanoparticles to escape because of its size, the normal means of discovery would not be prudent for smuggling into the environment and the human body. We already live in a world where nano materials in quantity, but the new release to the atmosphere of non-biodegradable nanostructures such as carbon nanotubes, could be a risk than exposure to asbestos, the lack of adequate tools for measuring the nanoscale, of course, makingDell Vostro 1510 battery detection more difficult.

The problem of biological effects and degradability: Not known at the time the possible effects of the drug nanocarriers of the physiological mechanisms of the body, including passage through biological barriers such as the barrier between blood and brain. Low biodegradability can also increase or increase the pollution and toxicity in humans.

The question of a possible "new features" of the material dell inspiron 1300 battery transported in the nanometer range, the mass / area, even more important for complex molecular systems in nanoscale materials, which may be older, have unknown consequences in relation to biological and chemical reactivity , and currently there are no known side effects of possible changes in the behavior of matter. The radioactivity is an example of the unpredictability of the effects of changes in the behavior of the raw materials are convinced that the knowledge of its effect in the last minute. The discovery of these "news" of radioactive material, which is traceable and had discovered that he could not support or protect.

Control over the dell inspiron 1564 battery development of nanotechnology: the global academic and industrial efforts in nanoscience and nanotechnology is estimated at $ 10500000000, according to the "assessment of the nanotechnology market Realastic" BCC Research report, published in July 2006. $ 4600000000 to public spending, the contribution of the United States about 35% (or about $ 1.6 billion), with a similar proportion of Asia, a contribution of just under 28% in Europe (1.3 million dollars ) and only 2% of the rest of the world. United States, the level of public spending in nanotechnology is now a year of almost a billion dollars, making it the largest Dell Vostro A840 battery scientific project with public funds from the first Apollo program. The Defense Department receives the majority of the budget of the United States government iPod nano. At least 35 countries have a national nanotechnology research.

Almost all companies among the 500 world premieres to invest in research and development in nanotechnology, accompanied by hundreds of small start-ups.

Around the world in 2006, was published as a $ 10.5 billion for research and development of nanoscience and nanotechnology, have been only $ 40 million for research on possible side effects. Dedicated in other words, only 0.4% of global spending on research risks, including health.

At the moment we can only establish the lack of enthusiasm of biologists, toxicologists, epidemiologists and environmentalists on these issues may be of a serious health problem has become.

The race for patents for nanotechnology products and processes, such as what happened, biotechnology can monopolies on the basic elements that lead

the origin of the natural world as a whole. If current trends continue, nanotechnology will continue to concentrate economic power in the hands of multinationals.

We are witnessing the same phenomenon, as the beginning of nuclear power and GM virtually no public debate.

IV Recommendations

The "nano" ingredients for at least seems explosive. But décelons, the sign of a protest in the history of the company.

Today, only scientists, environmental organizations and associations, the role of HP Pavilion DV7 informants (ETC in Canada, "parts and labor" in Grenoble, Greenpeace and Friends of the Earth) is played. There is an urgent need for national and local joint committees in which researchers, entrepreneurs, politicians and civil society come together. It 'important to have opted for a positive message of life and avoid the company to form a discourse of anxiety. Above all, we need the ecological and social success for all citizens to join.

It seems so urgent that sufficient information on the properties of nanoscale systems feared that may be able to penetrate biological barriers, particularly between the blood and the cross of the brain, and is currently limited or non-biodegradable, which are outside therapeutic indications of important consequences for our health needs. Also, is mainly to provide all the necessary HP Pavilion DV3 measures to protect workers handling nanomaterials, and the containment of the study sites and production of nanomaterials. Priority will also look for adverse effects in studies on the toxicity of low doses of those most at risk, including workers in contact with nanomaterials that could have exposed, despite the assurances, as a precaution, pregnant women should be excluded from these positions. Monitoring of fetuses and infants should be legally at risk of occupational exposure and accidental may be required. HP Pavilion DV3000 battery Research in animals from the effects of nanoparticles must be strongly developed nanomaterials, but not strictly medical (eg, nano cosmetics).

At present, the setting in the security structure to control these new products. Therefore, you must:

Committees in the context of the hygiene and occupational health and safety "rather than requiring each laboratory, the research team and place of production, written guides to good practice and procedures for monitoring the implementation of special protection and control of personal research and industrial products at the nanoscale;

Promote networks of information agencies: AFSSAPS biomedical, AFSA, and the Institute of Public Health. More attention should be paid to the HP Mini 1000 battery principles involved, how to pay respect for privacy, informed consent for the administration or exposure to nanoparticles again, equal access to these innovations, the protection of persons. This is a database of health. In these organisms, is also to identify conflicts of interest so as to greatly reduce and possibly eliminate;require manufacturers to provide information and a product intentionally produced nanoparticles visible so that the consumer may be able to refuse to use the mark;the Asus Eee PC 701 battery establishment of an effective public information and society through the organization of public debates in itself contradictory and decentralized regional units and lead to public documents, supplemented by the reactions of scientists and industrialists, questions, hopes and fears expressed in these debates.

Conclusion:

This is not out of nanotechnology in question, or to demonstrate a major anti-science and scientism. The problem of nanomaterials is identical to that of GMOs: the short-term interests of the sector is vital to protect the citizens and the environment. And so it sold the first safety studies required. Liability policy, at this point SONY VGP-BPS9 B battery is remarkable, and the applicable regulations and laws wholly inadequate to the peculiarities of nanomaterials (for example, are in the REACH regulation, which, thanks to its small tonnage) is. However, moving from political pressures is critical citizens, not more, compared with GM. The problems, which are made using nanotechnology too serious to rely solely on the services sector in order to solve them.

Will hydrogen be a fuel in the coming future?

Discovered by Cavendish, is the "hydrogen", the French version of Lavoisier. He found that when approaching a lighted candle near a pipeline that causes the appearance of the flame and combustion gases causes the formation of water on the walls of the sample. Antoine Laurent Lavoisier Asus Eee PC battery decided to call this hydrogen gas, from the greek water "hydro" and "gen" (producer, creator).

Although there are many in the world, there is a natural state is not with other atoms (C, O), such as water or methane (natural gas) is connected. And 'therefore necessary to produce or electrolysis of water, is the reform of the oil or algae ...

The problem, if it is a matter of hydrogen or, more generally,Asus Eee PC 901 battery  is the future / fuel ratio, which sails between optimistic and pessimistic a hard heavy. And fuel cells, hydrogen fascinating. And 'interesting because:

- Frequency - at least in the form of water,

- Ability to solve environmental problems (greenhouse effect) has been the combustion of hydrogen with oxygen produces only water,

- Reduce reliance on fossil fuels and the limited availability of them (do not produce hydrogen from natural gas ..)

It could be the key to the use of renewable energy, particularly solar and wind, in order to store this energy in a chemical form for later use. Hydrogen seems to be a "clean" fuel.

A few dream of a "hydrogen economy, while" in which hydrogen will replace traditional fossil fuels, and it would be an important source of energy production. Hydrogen is certainly a great variety of applications in the speech of petrochemical, food, electronics, glass, air and space, but not the expansion of transportation or Asus Eee PC 1201N battery electricity, the supply of computers and other PDAs ..

But this dream is reality?

An increase utilisition hydrogen requires a lot of problems can be solved:

- The first production, because hydrogen is currently produced, mainly by reforming of natural gas. But the natural gas resources, while important,Asus Eee PC 900 battery  are not unlimited, and the use of natural gas does nothing to solve the problem of CO2 emissions.

- Create the inherited infrastructure of production, but also the transport, storage, distribution, ... This requires that the technical problems are solved and this solution economically and ecologically sustainable.

Finally, there is the eternal problem of eggs and chicken. Which comes first: hydrogen or batteries? The structure and hydrogen needed for the operation of investment demand in a relevant market, Compaq Presario CQ70  battery and the batteries are better with hydrogen.

And 'in every case, a transition period, technological advances, the political will on the part of officials, an attempt by the oil industry and acceptance by consumers to accept. In all cases require the technology or technologies related to hydrogen can be related to energy efficiency and CO2 emissions in order to win.

End of 2008: Where is it?

Politically, many associations, research programs and obligations, and measures to facilitate the development of hydrogen vehicles.

In October 2007 the European Commission adopted two proposals for the development of hydrogen technologies provide. The Joint Technology Initiative (JTI) on fuel cells and hydrogen are: There is an integrated program of research, technological development and demonstration, in collaboration with industry. The program must implement the age of 6 years, an EU contribution of € 470,000,000 is based, HP Pavilion DV5000 battery as well as a similar contribution in the field. ITC aims to accelerate the commercial development of hydrogen over the next ten years. The Commission also aims to facilitate the market entry of hydrogen vehicles, to facilitate their reception. In fact, in September 2008 the European Parliament adopted a regulation on European standards for the registration of vehicles powered by hydrogen. This will be the development of these cars,HP Mini 1000 battery while a more detailed framework for the producer.

United States, President Bush announced in 2003 to develop a $ 1.3 million for research on hydrogen-related technologies. The project is funded by the Department of Energy manages a budget of about $ 200 million a year since then. Some HP HSTNN-DB72 battery states are more advanced than others, like California, where they accumulate projects.

Commitment and support for hydrogen differ from country to country, depending on the results of these studies are the individual decisions of this brand to be like turning the hydrogen in Iceland to Norway, which began in 2004, the project terms of the independent island of energy generated from hydrogen production by hydrolysis of electricity from wind turbines. Denmark HP Pavilion DV5 battery has also to be considered in the beginning, hydrogen generated by wind turbines.

Have been used in applications, in particular cars. In 2008, Honda plans to lease the individual of 200 hydrogen vehicles, the FCX Clarity, California and Japan over the next three years. Stations may use the Shell and other companies. Progress is made in respect of the autonomy given a big problem with service stations limited. The following Chevrolet, GM has traveled 480 km on one tank of gas in 2007. Thirty of Ford vehicles will be tested for professionals in the United States since 2005, but also Canada and Europe. The contract, initially for three years could be extended until 2010. F-Daimler Chrysler vehicles in circulation in Europe and the United States. Since 2003 hydrogen buses begin the streets of Europe since 2003, which was distributed to the creation of hydrogen filling stations in Europe: The Reykjavik already been installed at the end of April 2003,Toshiba PA3399U-1BRS batteryfollowed by another Barcelona, ​​Hamburg and United States (Washington, California) and Japan.

In order to evaluate the progress and the attention for hydrogen, it is interesting, the show car, presented in the following terms of research and prototyping.

In 2007, BMW presented the BMW Hydrogen 7 luxury sedan of an operating system with both petrol and hydrogen. Volkswagen introduced the Space Up hydrogen, a hybrid battery / hydrogen Toshiba Satellite A100 battery in Los Angeles. Fiat Panda Aria has launched a prototype version with a natural gas doped with hydrogen. Far from being a vehicle of pure hydrogen, but the path to reduce emissions. Some concept cars of the type of Italdesign VAD.HO were also presented.

In 2005 the Geneva Motor Show in Detroit and Frankfurt, hydrogen vehicles are still the focus of attention, even though hybrids are hot right now and steal the show as well. We have yet to see the new prototypes: Daimler introduced its zero-emissions vehicle based on a Class B (instead of the F-Cell vehicles) as a result of General Motors with a battery and a lithium ion battery, Dell Studio 1537 battery ,Ford Focus C Max-combustion engine of a hydrogen engine, the Audi A2, H2, Michelin Hy-Light prototype, the concept car Mitsubishi Nessie.

The Paris Motor Show (October 2004) BMW H2R prototype was introduced with a hydrogen combustion engine, a Peugeot quad, cottage cheese with hydrogen. It 'was a step above the Auto Show in Paris (October 2002), where they were introduced several prototypes of hydrogen vehicles: GM Hy-Wire, red for fire vehicles H2O PSA, Dell Studio 17 battery and even motorcycle and a bicycle.

General information on hydrogen

Hydrogen (actually hydrogen) is an odorless, colorless, very easily (by plane) and is composed of two atoms of hydrogen. Their general properties of the table below.

Energy Power

Hydrogen has a high gravimetric energy content: Oil 120 MJ / kg (45 MJ / kg), methanol (20 MJ / kg) and gas (50 MJ / kg) were compared. The gas is also lighter (2016 g / mol H2), as a low volume: 10.8 MJ/m3 face with methanol (16 MJ/m3), natural gas (39.77 MJ / m 3). This represents a problem for storage and transportation: If the use of hydrogen in a vehicle or a tube of public transport, which is a truck, the apparent density that matters. The volumetric Dell Studio 1735 battery energy density of H2 is interesting that a liquid or compressed (700 bar).

The safety aspects of

The hydrogen reacts with oxygen, releasing water and heat (290 kJ / mol H2). The combustion of hydrogen in air, no formation of carbon-sulfur derivatives, however, Dell Studio 1737 battery was the formation of small amounts of NOx by the reaction of nitrogen from the air, with some O2. Because of this reaction one of "problems" of hydrogen is flammable and explosive. Because if Hindenburg (destruction of the dirigible Hindenburg in 1937), hydrogen has a bad reputation, but research has shown that the incident was not the hydrogen, but the flammability of the hull of the aircraft.

The flame is barely visible to the eye - which can be dangerous for aid workers in case of fire, the temperature is 2300 ° C in air.

Hydrogen has a wide range of inflammabilitédans air: 4-75% (compared with 5-15% methane), which increases the risk of a hydrogen-rich gas - for example, near a loss. These conditions apply to a temperature and pressure, depending on the temperature and pressure, and the presence of other components of the mixture of inert gas.

The ignition energy is very low (10 times lower than in other hydrocarbons) to 0.02 mJ.

In some cases, the birth, you can witness an explosion. There are two types of explosion: An explosion and detonation, which can sometimes be a transition from deflagration to detonation.

However, hydrogen in the air to spread very rapidly as a result, in the event of a loss of hydrogen escapes upward and its concentration decreases rapidly below the lower explosive limit, which means a safety factor .

Finally, because of its low density, hydrogen tends to escape through micro-holes is possible.

The security aspect should not obscure the fact that hydrogen has been used in industry, and that before the war, the city gas is composed of 60%. Check that you Dell Vostro A840 battery have risks associated with hydrogen has been the subject of intense research, especially in nuclear power plants that hydrogen can be produced in an accident). The first is the possibility of hydrogen accumulation in the blast zone should be reduced, which could reduce the volume of hydrogen gas, and then passes to avoid detonation. They are the means of prevention such as:

the addition of an inert gas (nitrogen-type, CO2)

catalytic recombination of hydrogen with oxygen, using "recombination" autocatalytic passive (passive autocatalytic recombiners (PAR)) that the recombination of hydrogen and oxygen can flow to create the heat of reaction, promote convective mixing levels and prevent Flammability deliberately to prevent ignition of hydrogen, increasing the concentration and movement of the detonation. And 'the fuse that leads to the burning fuel mixture, but only at a concentration close to the threshold of flammability,Dell Latitude D830 battery and in places where the flame spread in the places of greatest concentration. Not the ignition systems of spark ignition and a catalytic igniter.

Ventilation to reduce the concentration of hydrogen in a closed container to dilute

If there is enough security for hydrogen also Ries. Of course it will be defined for each stage of production, transportation, storage and distribution, to ensure its use by the public. But the legislation still to be defined! At the moment there is no legislation on public consumption and use of hydrogen.

The project  HySafe ("The safety of hydrogen as an energy Year"), Dell XPS M1530 battery funded by the European Union, aims to create a network of 24 European partners (+ a Canadian), coordinated by the Forschungszentrum Karlsruhe. It aims to improve the safe use of hydrogen: simulations of cases of leakage of hydrogen limitation and prevention of damage, the standardization of risk analysis in case of fire or explosion.

Synthesis of Hydrogen

Production

Hydrogen production is 630 million m3 in 2007. Now the primary energy demand worldwide by more than 11 million tons of oil equivalent in 2007 (128,000 TWh) was, is, energy demand is expected prévisionde 55% according to the IEA (2007) to increase. The question is followed mainly by oil and coal gas dominates. This means that cover the current production is only 1.5% of demand, so there is plenty on the production of hydrogen reaches a substantial proportion who do is increasing, especially Dell XPS M1730 battery with the demand for energy worldwide.

Hydrogen is produced mainly by reforming of hydrocarbons. The production methods are:

- The steam reforming of natural gas (petrol)

- Partial Oxidation (oil, coal, heavy oil ..)

- Electrolysis

- In the production of ethylene-co-produced.

The first two techniques are almost 95% of total production.

Large groups specializing in the production of hydrogen: Air Liquide (Messer Griesheim), Air Products, Linde Gas, Mahler, Praxair, but also other companies such as Shell Hydrogen, Norsk Hydro, GHW (alkaline electrolyzers Dell XPS M1330 battery manufacturer MTU joint venture of Norsk Hydro and HEW ) are involved.

Use

When the hydrogen has an important role in the field, which is rarely used as an energy source (except missiles). Classically, it is mainly used in:

- The chemical and petrochemical industry (synthesis of ammonia, methanol, dyes, hydrogen peroxide)

- The glass industry,

- Electronics (chips)

- Food (unsaturated fats)

- Steel

- In the production of low sulfur fuels.

This is the generation of hydrogen for Compaq Presario CQ60 battery energy use, which seems to have no future, either with batteries or internal combustion engines. Ammonia production currently represents almost 50% of the consumption of hydrogen applications in the petrochemical industry and for the synthesis of chemicals (methanol, amines, hydrogen peroxide) followed. But in these cases, the cost of hydrogen production cost of finished goods are taken, especially because often centralized on a website. No account the energy is considered.

The dangers of exposure to wireless technologies

Our exposure to electromagnetic fields in mobile (mobile phone masts, WiFi, Bluetooth, etc.). This was a lot of concerns that the combination of Robin ceilings complaint on the basis of knowledge through seminars, the speakers are physicians and scientists. He decided to launch an information campaign about the dangers of drastic market launch of the club also focuses on the lack of accountability of governments and private operators to ignore the destructive effects of frequencies shown by these new SONY VAIO VGN-FZ140E Battery technologies.

The Microwave Syndrome

Our body, wonderful small electrical machine is determined by the natural electromagnetic signals that feed the muscle, nervous system, heart and brain. However, these SONY VAIO VGN-FW21E Battery signs are in resonance with an artificial micro-currents of very low intensity in wireless technologies, our senses must not be interpreted in terms of struggle, much less obstruct the proper functioning of our body. According to the World Health Organization, swam in a continuous radio frequency damaging fields, without even realizing it.

Many scientific reports have provided compelling evidence of the damage caused by exposure to radiation on human health are available: DNA damage, interfere imunitaire and nervous system, increased stress, the development ofSONY VAIO VGN-FZ280E Battery cancers such as leukemia or cancers of the brain, the acceleration of Alzheimer's disease, behavioral problems, skin diseases, reproductive, psychological, etc.. And the list goes on ...

The report BioInitiative European Environment Agency and validated by the European Parliament in 2008 brought the sad misfortune, scientific discoveries about the health effects of mobile phones.

The speech is inconceivable to imagine a distribution of these technologies if they were dangerous, not so good, especially because the phone is no longer covered by insurance since 2000 in the world ... It 'strange, remember the story of asbestos.

If you do not listen to the government and industry, which is all of us to behave responsibly, how to use these technologies, which are totally dependent.

Here are some tips from organizations that fight for the safety of people exposed to wireless technologies:

Mobile phones in the house, such as DECT (1) spread to high frequencies is communication, it is better to opt for the fixed line long ago.

For mobile phones, we must focus on a device SONY VAIO VGN-FZ battery with a SAR (2) as low as possible (less than 0.5W/kg) and avoid using the headset cable that transmits the signal in the same cave ear to the brain. Close any case, most of the conversations brief and avoid public transport and car reduces exposure to radiation more.

WiFi high-frequency units, and between the computer and cable internet. The ideal is to pack the box with fabric anti-high-frequency radiation should be sufficient.

Recently the press reported that the state is in this summer, a competition for licensing mobile-Internet 4G (fourth-generation mobile standard). These juicy lead € 2.5 billion, in order to understand his enthusiasm. Néanmois seems less logical is the total absence of impact assessments and know-how to promote these new SONY VAIO VGN-FZ35 Battery technologies.

Given this gross negligence, organizations are in an action plan to mobilize members of the Council of Europe.

First, the implementation of awareness campaigns on the risks of adverse health and the environment a priority by developing a close relationship with the ministries of environment and education, the dissemination of information on the project by teachers, parents and children - are particularly sensitive to exposure to microwave -.

The SONY VAIO VGN-FZ240E Battery need for a threshold level for the prevention of exposure to microwave no later than 0.6 volts per meter is also set an emergency situation and a stimulus to the actual work of research and development of telecommunication technologies in I'm still a neutral effect on our environment on the basis of, or at least compatible with it. This was the idea of ​​a property tax can exceed the thresholds proposed care, thus contributing to an increase in public research funds.

On the other hand, it seems obvious is not necessarily for the operators: each unit contains a detailed risk assessment experience to pre-market and a written simply, the presence of microwave emissions and the SONY VAIO VGN-CR72B/W Battery power of the device should be mandatory.

It is also considered, shall define the electro EHS (electromagnetic susceptibility) syndrome, intolerance to electromagnetic fields and the creation of "white space" is essential to avoid them if they live at home or caulking emmitouffles special clothing from head to toe want. As Robin explains the association of the ceilings, "it is important that 20% of the French region of potential sources of microwave SONY VAIO VGN-CR31S/D Battery radiation, otherwise it is impossible to prove scientifically the origin of the possibilities and the health problems of these new media technologies."

The situation is alarming and will be a real public health problem, if warnings are not taken seriously, or if the interests of industry dates back before the health of the population. To keep Compaq Presario CQ62 Battery no technophobe, it is essential that the fundamental principle of democracy, it is still possible, even for our own good, and act for the next generation.

The child: the first victim of electromagnetic radiation

As mentioned many times the innocent are the first victims of our mistakes. Electromagnetic pollution on children has been demonstrated by several studies, including the United States. Some show a link between autism and exposure to wireless technologies since the late '90s, a period that coincides with the explosion of mobile telephony and the use of Wi-Fi. "Electromagnetic radiation, it seems that heavy metals HP Pavilion DV4 battery into the trap of the cell, reducing its elimination and accelerates the onset of symptoms. An increase of this magnitude can not be a factor of the main results of this environment to provide a method of mechanical explanation satisfied the relationship between autism and wireless technology. "(3)

Scientists believe that children exposed in the vicinity of power lines are also prone to emotional problems, hyperactivity, or appearing at the time of enrollment, the more serious HP Pavilion DV7 battery problems if the mother has had a bad cell phone use during pregnancy. And in fact, through the radiation pulse power is such that penetrate the walls and therefore more easily in the human body.

It 'also important that the fetuses of non-ionizing radiation (propagation of high frequency electric fields are not of natural origin) from other devices, such as induction product HP Pavilion DV6 battery to protect the fetus and have an exposure to electromagnetic waves of much higher level when the mother has the maximum allowable exposure time.

The facts are well represented. Our dependence on these technologies is real. But if you can not go back, it's still a way to protect against the devastating effects of radiation. There are enough "brains" of the situation, the development of sustainable technologies, sustainable environment for the survival of the species of plants, animals and long-term rights. Not passive, ignorant and vulnerable to act responsibly and at least for future toshiba pa3465u-1brs battery generations if they are not for us.
