THE EARTH [LIVING IN DIFFERENT WORLD]
Today man’s modern lifestyle and insufficient utilization of conventional fuels are being considered for huge power losses. Fossile fuel combustion and emission of (green house gasses having hing temperature in it cause green house effect ex:CO2 , CO etc) from industries and vehicles are considered as a cause of temperature increment in the environment.
The effect of global warming is due to rapid consumption of fossile fuel deforestation man’s luxurious lifestyle and emission of CO , CO2 from industries and vehicles which all are not only responsible for global warming, but(these also things) responsible for degradation of human health scarity of fresh drinking water and air pollution.
These things alters the complete cycle of Ecology system in the environment.
It means the global warming changes the scenario of the whole planet.
Now a days we might have observed that world is frequently facing large haricanes, droughts, floods,earth quick,and volcano blasts which cause the millions of people death and after the wild as well as underwater life.
Now lets comes to the main point of the article that is know about global warming .
What is global warming ?
Ans : Well “It is the increment in the average temperature of earth surface”.
The sentence seems to be very simple,but it creates disaster effects as discussed above.
Hence its really necessary to avoid the depletion of natural resources,ozone layer and ground water and protect the forest from the deforestation.

ENGINEERING KNOWLEDGE TEST FORM-2011
NOISE
Electronic noise
Main article: Noise (electronics)
Electronic noise exists in all circuits and devices as a result of thermal noise, also referred to as Johnson Noise. It is caused by random variations in current or voltage caused by the random movement of charge carriers (usually electrons) carrying the current as they are jolted around by thermal energy. Thermal noise can be reduced by reducing the temperature of the circuit. This phenomenon limits the minimum signal level that any radio receiver can usefully respond to, because there will always be a small but significant amount of thermal noise arising in its input circuits. This is why radio telescopes, which search for very low levels of signal from space, use front-end low-noise amplifier circuits cooled with liquid nitrogen.
There are several other sources of noise in electronic circuits such as shot noise, seen in very low-level signals where the finite number of energy-carrying particles becomes significant, or flicker noise (1/f noise) in semiconductor devices.

Drug addiction, alcohol abuse, and alcohol addiction are common occurrences in today’s social setup. Some people can’t party without food and good music. Some can’t party without popping Ecstasy, snorting coke, or overindulging in the consumption of alcohol. These things seemed to have become as normal as breathing, but on an entirely different and harmful level.For things that have assumed a certain form of normalcy in our society, there sure are a lot of adverse effects stemming from them. In the financial aspect, people with an addiction or a substance abuse problem spend over $365 billion each year to pay for health care, criminal justice, and the loss of productivity in the workplace.In matters of public safety, the whole community is affected. It has been found that alcohol kills 6.5 times more adolescents than all illegal drugs combined. However, drug addiction doesn’t get away scot-free because this problem is linked to at least half of the major crimes in America. And of the suspects arrested, at least half of them were under the influence of drugs when they committed the crime.On a more important note, the ones most affected by substance abuse and addictions are the direct party involved: the family and the individual himself. The relationship between family members can be distressed due to domestic 
physical and verbal violence brought about by personality change. The family may fall into financial crisis because the victim will inevitably use family funds to pay for the vises luring his life.However, no matter how dire the situation may be there is always hope. As they say, “When you hit rock bottom, there is no other way to go but up.”The first step to recovery lies in the patient himself. Addiction treatment, and also substance abuse treatment, needs to start with the proper psychological and mental disposition of the patient. There is nothing harder than asking someone to get better when there is no desire from the person to do so. If a person admits that there is a problem and that he wants to do something about it, the battle is already half-won.It is then crucial to find the perfect facility to house the patient. Patients on the road to addiction recovery can achieve a sense of personal empowerment with the help of trained and caring professionals. The environment can also play a great part in the patient’s recovery. There are some facilities that only prov
ide treatment after the person has been detoxified. Other rehab centers provide care during the detox process and then give the appropriate treatment after.Alcohol abuse and other forms of substance abuse and addiction can be detrimental to the person, his family, and the society at large. For those seeking treatment, they may feel lost and alone. But they certainly need not to. Many people out there care for those who want to be better. Addiction treatment will always be available to those who ask. To those people who persevere, addiction recovery is not simply an attempt at the impossible.If you want to know more about alcohol abuse then feel free to visit addiction treatment center at drugrehabsunsetmalibu.com.

window.google_render_ad();Not so long go, a well-known newspaper tabloid regularly splashed a sequence of socially conscientious stories, as to how some kids from a renowned school were planning to redefine the way we Indian shop vegetables. Yes, vegetable shopping became focus point, given the fact that many of us fail to carry bags from home when it comes to buying vegetables. And therefore purchase vegetables in plastic bags that’s freely available with vendorsSo, these school kids , well-aware of the disastrous consequences of using plastic bags, did what the adults should have done way back… design paper bags from newspapers and sell them to the vegetable vendors at an affordable rates.But as they, old habits die hard; we are back to ground zero, as people have gone back to their bad old ways of using plastic bags. So what went wrong with the children’s campaign of popularizing paper bags? Why did the concerned newspaper cease to carry more stories on it? We don’t the reason why?As of now, what we know is that the use of plastics have increased like never before and this can wreak havoc in the environment as most of them are not biodegradable, therefore not environment-friendly.But living in a world without plastic is an unimaginable prospect; given the fact plastics over the years have become a fundamental part of our living.Advantageous of plasticsThe significant growth in use of plastics is due to its favorable properties. These include:• It's Versatility and can be customized to meet very specific technical needs.• Light in weight as compared to other materials, leading to less fuel consumption during transportation.• Very durable• Resistant to chemicals, water and impact.• Hygiene properties in terms of food packaging.• Thermal and electrical insulation properties.• Inexpensive to produceAs per the latest reports, people world over manufacture and use 20 times more plastic today than we did 50 years ago!Plastic products are used for all and sundry purposes. The kind of products produced from plastics include, Industrial Plastic Products, Plastic water tank, Pet Preforms, Plastic Aircraft Products, Plastic Automotive Parts, Plastic Bags, Plastic Balls, Plastic Barrels, Plastic Basins, Plastic Baskets, Plastic Bins, Plastic Bottles, Plastic Bowls, Plastic Boxes, Plastic Buckets, Plastic Prefab Homes, Plastic Canisters, Plastic Cans, Plastic Capacitors, Plastic Caps, Plastic Clothings, Plastic Coatings, Plastic Mugs, Plastic Packaging Products, Plastic Panels, Plastic Pallets, Plastic Pipe Fittings, Plastic Pipes, Plastic Sanitaryware, Plastic Sheets, Plastic Stationary, Plastic Straps, Plastic Strips, Plastic Tanks, Plastic Tapes, Plastic Toiletries, Plastic Toys & Games, Plastic Trays, Plastic Tubes, Plastic Tumblers, Plastic Vases, Prefab Homes, Plastic Yarns …the list is long. So it is plastic and plastic everywhere.So it is safe to surmise that plastics have made their presence felt in a big way in our daily lives. Packaging industry is reported to be the single largest sector using plastics. So doing away with them completely is not that easy, considering its significant influence in our daily lives, however, one can chalk out various strategies to make the most use of them, thereby restrict their production.There are 50 groups of plastics with hundreds of varieties. The best thing being all varieties can be recycled. However, reusing plastic is preferable than recycling as it uses less energy and fewer resources.Degradable plasticsNumerous retailers in UK have recently come up with degradable carrier bags. These bags are made from a special type of plastic that degrades under certain conditions. For instance, degradable plastics are of two types, bio-degradable plastics and photodegradable plastics. Bio-degradable plastics c
ontain only a small amount of non oil-bases material, like corn starch and photodegradable plastics will break down when kept under the sun.Degradable plastics are widely being used in countries like Austria and Sweden, where fast-food retail chain McDonalds has been using bio-degradable cutlery since three years. Plastic which photo-degrades in six weeks are been used in manufacturing carriers for beer cans.Bio-plasticsAs hazardous chemical additives are used in plastics, leading to health and safety concerns, manufacturers are gradually shifting to plant-based plastics. For instance, world’s largest toy manufacturer Mattel had announced that company will be using plant-based plastics for manufacturing of toys. Similar promises were also made by companies like LEGO, IKEA, Nike and The Bodyshop. So hopefully, within few decades, we could expect the whole world shifting towards using plant-based plastics.How to prepare yourself for Psychology
