Depression

by salman on Feb 23, 2011 Knowledge, science Comments Closed • ,

Depression:

Depression is sadness, pessimism, personal problems, and perhaps feeling sorry for one’s own self. It has anguish, crying, bothering and hopelessness. Activities and social contacts seem so huge of a task because of loss of pleasure in and enthusiasm for their usual activities. Low energy, chronic tiredness, excessive sleeping, and insomnia are common.

There is no dearth of symptoms of depression; the list can keep on growing. Other symptoms can be poor appetite, heavy eating, weight loss or gain, feelings of inadequacy or worthlessness, anxiety, regrets, decreased productivity, poor concentration, or recurrent thoughts of death or suicide. The very own social animal definition of humans beings is at loss in case of depression.

Depression is one of the worst mental illnesses one can take or experience. Depression is something which can run in families. It usually starts between 15 and 30 and women are the most affected people. Depression is one pole of the bipolar disorder. (more…)

Co-education

by salman on Jan 9, 2011 Better life values, Careers, Knowledge, science Comments Closed • , ,

Co-education

Co-education is a system of giving education to both sexes together. It has many consequences. It is economical and frugal. It generates a spirit of comradeship between boys and girls.

The problem of shortage of trained teachers can be dealt with by this system. Boys overcome their curiosity and girls, their shyness. They learn to respect one another. Though a few conservative people are against this system, their views do not hold ground. Co-education generates harmonious relationship, a sense of co-operation, and thus, helps in the progress of the nation.

Today, co-education is prevalent in almost all the countries of the world. In India, there are a number of co-educational schools, colleges and universities.

There are a number of advantages in the co-educational system of education. It is economical. Poor countries cannot afford to open separate schools for boys and girls. If boys and girls are taught together in the same school, then there will be no need to open separate schools for them. Thus, the cost to be incurred on building infrastructure, furniture, stationery, personnel recruitment, etc. will be saved.

There is a shortage of good trained teachers in developing countries like India. If there is co-education, same staff can teach both boys and girls at the same time in the same class, and the problem of shortage can be dealt with. Establishing more of co-educational schools can help in spreading literacy even with the limited teaching staff and infrastructure. Thus, it will be beneficial for both boys and girls and the nation as a whole.

Co-education helps the boys and girls to intermingle and understand each other well. They become more broad-minded and tolerant towards the opposite gender. They interact freely with one another, thereby overcoming hesitation and shyness. Thus, co-education leads to a healthy and harmonious relationship between boys and girls.

In a co-educational school, boys are free to meet and talk with girls. They develop a feeling of friendship among themselves. Boys then, usually don’t indulge in eve-teasing. Co-education contributes to the balanced development of the personality of boys and girls.

A new study has revealed that the co-educational schools are better as the presence of girls in classes restrains boys from indulging in unruly behavior and improves their academic performance. Infact, a higher percentage of girls not only lowers the amount of classroom disruption but also fosters a better relationship between students and their teachers. The researchers found that classes with more than 55% of girls resulted in better exam results and less violent outbursts overall. Boys with more female peers in their classes showed higher enrolment rates in both advanced mathematics and science classes, but overall benefits were found in all grades for both sexes. They conclude that this effect is due to the positive influence, the girls are adding to the classroom environment.

Infact the study found that primary school classrooms with a female majority showed increased academic success for both boys and girls. In the middle and high schools, the classrooms which had the best academic achievements overall were consistently those that had a higher proportion of girls enrolled. The researchers suggest that boys and girls may learn differently, but it is better not to send them to sex-segregated schools.

Boys become conscious of their dressing habits, behavior and the style girls. They work hard to remain ahead of one another. Co-education reduces gender bias in the society. It generates a feeling of equality between both and sexes. The feeling of male dominance may be wiped out from the society if this system of education is given importance.

However, some people are opposed to the system of co-education. According to them, this system is against the Indian culture and tradition. It is also argued that girls feel freer in an institution which is meant only for girls. As such they have greater scope of developing their personality. They also participate in sports, dramatics and debates more freely.

Teachers of some subjects like Biology also find it easier to explain some chapters more thoroughly if only girls or only boys are sitting in the class. Sex education has also been introduced and in co-educational schools even teachers find it difficult to discuss such topics in the class.

It is also felt that since students (especially teenagers 13-19 years of age) are of impressionable age, the possibility of their going astray is much more in co-educational institutions, where they enjoy more freedom of intermingling with the other sex. They also do not remain focused on studies.

It should be acknowledged that in the fast changing society of twenty first century co-education has to become the order of the day. Today girls are entering all professions in large numbers. Many of them are heading big organizations. Co-education will help young boys and girls to mix freely and understand one another better. Today’s children are tomorrow’s citizens. We must encourage them to develop their personality in a free healthy atmosphere. Girls no more have to remain confined to the four walls of the house. Co-education will help both sexes to learn and work together for the progress of the country.

Drug Addiction and Risks

by salman on Jan 16, 2011 Protest, science, World News Comments Closed • , ,

Drug Addiction and Risks

Drug addiction is compulsive use of a substance despite negative consequences which can be severe; drug abuse is simply excessive use of a drug or use of a drug for purposes for which it was not medically intended. Dependence on a substance is not necessary or sufficient to define addiction; there are some substances that don’t cause addiction but do cause dependence (for example, some blood pressure medications) and substances that cause addiction but not dependence (they are mainly characterized by depression).

Causes, incidence, and risk factors

Drug abuse can lead to drug dependence or addiction. Drug addiction may also follow the use of drugs for physical pain relief, though this is rare in people without a previous history of addiction. The exact reason of drug abuse and dependence is not yet known. The genetic make-up of the individuals, peer pressure, emotional distress, anxiety, depression, and environmental stress are all factors which seem to be involved. Children who grow up in an environment of illicit drug use may first see their elders using drugs. This may put them at a higher risk for developing an addiction later in life for both environmental and genetic reasons.

Commonly abused substances include:
- Opiates and narcotics are powerful painkillers with sedative and euphoric qualities. These include heroin, opium, codeine, Oxycontin and others.
-  Central nervous system stimulants have a stimulating effect and can produce tolerance. These include amphetamines, cocaine, commonly used stimulants are caffeine and nicotine.
-  Central nervous system depressants produce a soothing sedative and anxiety-reducing effect and which leads to dependence. These include barbiturates (amobarbital, pentobarbital, and secobarbital). Commonly used depressants, by far, is alcohol.
-  Hallucinogens produce psychological dependence. These include LSD, mescaline, psilocybin (‘mushrooms’).
-  Tetrahydrocannabinol (THC) is the active ingredient found in cannabis, marijuana, and hashish. Although used for their relaxing properties, THC-derived drugs can also lead to paranoia and anxiety.

Drug intoxication and drug overdose may be accidental or intentional. Drug withdrawal symptoms can occur when use of a substance is stopped. Withdrawal symptoms vary, depending on the particular substance. The withdrawal symptom depends on the length of time the drug was being used. Drug intoxication, overdose, and withdrawal can be life-threatening in some situations.

Treatment for the person with drug addiction begins with the recognition of the problem. Though earlier ‘denial’ was considered as a symptom of addiction, recent studies has shown that this symptom can be dramatically controlled if addicts are treated with love and care, rather than being told what to do or ‘confronted.’ Treatment of drug addiction involves detoxification, support and abstinence. Emergency treatment may be indicated for acute cases. Often, there may be a loss of consciousness and the person may need special medical attention temporarily. The specific treatment depends on the drug. Detoxification is the gradual withdrawal of an abused substance in a controlled way. Sometimes a drug with a similar action is substituted during the withdrawal process to reduce the unpleasant symptoms and risks associated with withdrawal. If depression or other mood disorder exists, it should be treated appropriately. The need for treatment is underscored by the severity of illness of those who undergo detoxification and the societal costs of untreated substance use disorders.

GSM

by salman on May 6, 2010 Knowledge, science, US Comments Closed •

GSM
(Global System for Mobile communication) is a digital mobile telephone system that is widely used in Europe and other parts of the world. GSM uses a variation of Time Division Multiple Access (TDMA) and is the most widely used of the three digital wireless telephone technologies (TDMA, GSM, and CDMA). GSM digitizes and compresses data, then sends it down a channel with two other streams of user data, each in its own time slot. It operates at either the 900 MHz or 1,800 MHz frequency band.
GSM is the de facto wireless telephone standard in Europe. GSM has over one billion users worldwide and is available in 190 countries. Since many GSM network operators have roaming agreements with foreign operators, users can often continue to use their mobile phones when they travel to other countries.

The Future of GSM
GSM together with other technologies is part of an evolution of wireless mobile telecommunication that includes High-Speed Circuit-Switched Data (HSCSD), General Packet Radio System (GPRS), Enhanced Data rate for GSM Evolution (EDGE), and Universal Mobile Telecommunications Service (UMTS).

GSM Network Operators
T-Mobile and Cingular operate GSM networks in the United States on the 1,900 MHz band. GSM networks in other countries operate at 900, 1,800, or 1,900 Mhz.
GSM Security
GSM security issues such as theft of service, privacy, and legal interception continue to raise significant interest in the GSM community. For information on GSM security, visit the GSM Security portal.
Books on GSM
The digital standard known as the Global System for Mobile (GSM) has captured a large share of the global cellular market. This book aims to bridge the gap between a reader’s basic knowledge of telecommunications and the complexities of the 5000-page GSM technical specification. It describes the system as a whole, covering all aspects of the standard, including mobile stations, switching equipment, the radio interface, infrastructure, transmission methods, and signaling protocols. System architects involved in the design of personal communications systems will find the book to be a complete description of the GSM communications system. It also may serve as a general introduction to digital cellular systems. (more…)

Most of world exposed to deadly tobacco smoke

The risk of ADHD was higher among children exposed to tobacco and lead.

The risk of ADHD was higher among children exposed to tobacco and lead.

More than 94 percent of the world’s people are not protected by laws against smoking, leaving them exposed to the biggest cause of preventable death, the World Health Organization said on Wednesday.

In a Global Tobacco Epidemic report the WHO said smoke-free policies were crucial to reducing the harm caused by second-hand smoke, which it said kills around 600,000 people prematurely each year and causes crippling, disfiguring illness and economic losses reaching tens of billions of dollars.

The report found some progress had been made, with 2.3 percent of the world’s population, or around 154 million people, newly covered by smoke-free laws in 2008. But it warned of many more early deaths if governments did not act quickly.

“The fact that more than 94 percent of people remain unprotected by comprehensive smoke-free laws shows that much more work needs to be done,” said the WHO’s expert on non-communicable diseases, Ala Alwan.

Scientific evidence has unequivocally established that exposure to tobacco smoke causes death, disease and disability. Over the past four decades, smoking rates have fallen in rich places such as the United States, Japan and western Europe, but they are rising in much of the developing world. (more…)

Think of the origins of that staple of modern life, the cup of coffee, and Italy often springs to mind.

But in fact, Yemen is where the ubiquitous brew has its true origins.

Along with the first university, and even the toothbrush, it is among surprising Muslim inventions that have shaped the world we live in today.

The origins of these fundamental ideas and objects — the basis of everything from the bicycle to musical scales — are the focus of “1001 Inventions,” a book celebrating “the forgotten” history of 1,000 years of Muslim heritage.

“There’s a hole in our knowledge, we leap frog from the Renaissance to the Greeks,” professor Salim al-Hassani, Chairman of the Foundation for Science, Technology and Civilisation, and editor of the book told CNN.

“1001 Inventions” is now an exhibition at London’s Science Museum. Hassani hopes the exhibition will highlight the contributions of non-Western cultures — like the Muslim empire that once covered Spain and Portugal, Southern Italy and stretched as far as parts of China — to present day civilization.

Pollution

by salman on Feb 21, 2011 Health & Fitness, science Comments Closed • ,

Pollution:

Pollution is when water, air or land becomes very dirty. Pollution can come in 4 different types effecting different types of areas in the world. Air pollution effects the air, water pollution effects the water and marine life, land pollution effects the land destroying life and the environment and there is also noise pollution that can effect our hearing. We all contribute to pollution in some way or another. Whether it is be with a large amount or small amount we can still cause major damage to our health and the environment. Although we all contribute to help stop the increase of pollution. Very little people realize that pollution is very harmful because they don’t think of the environment, themselves and other people and what it can do. Pollution is an important factor to our lives. It involves our society and all other animals. Pollution is gradually destroying our planet and is gradually killing ourselves too. Like air pollution, smog and acid rain is a killer to all of us. It destroys marine life, our own health and destroys historical monuments and statues.

What is the worst kind of pollution?

When discussing the worst kind of pollution people talk about either water pollution or air pollution. Water pollution and air pollution not only harm our environment but also our health. Recent estimates say that around 15,000 people in the world die each day because of the water pollution, while according to the data from the World Health Organization 2.4 million people in the world die each year because of the air pollution.

Pakistani nuclear scientist Abdul Qadeer Khan.

The release of the Pakistani nuclear scientist AQ Khan from prison has prompted concern from the United States that he might again begin trading nuclear know-how and technology.

Khan was first questioned by Pakistani authorities after making deals with countries like North Korea, Libya, China and Iran.

Now allegations have surfaced that the Pakistani government sanctioned his work.

Khan was arrested in Pakistan in 2003 for trading nuclear secrets and technology to countries like North Korea and Iran.

In the UK’s Sunday Times, Washington-based analyst and journalist Simon Henderson has published sections of a letter written by Khan prior to his arrest.

“The letter is a statement to his wife, of what he did and under who’s instructions did he do it. And it is quite clear that everything that he did was with the approval and indeed at the instruction of successive Pakistani governments,” said Henderson.

Leonard Spector, Washington Director of the Monterey Institute, Centre for Non-Proliferation Studies, said this new evidence needed to be interpreted in context. (more…)

Why Islam forbids pork

by Abdullah on Jun 24, 2010 Health & Fitness, Islam, science Comments Closed • , ,

Food and drink have direct effect on our health. That is why Islam has prescribed regulations about our food and drink. It lays great emphasis on our physical as well as moral health, because both of these are equally important for a healthy society.

The abstention from eating pork is one of the steps taken by Islam to practise hygiene and to attain purity of soul.
Islam, for the cultivation of inner faculties, insists upon the cleanliness of body and the purification of soul through Salaat (prayers) Zikr (remembrance of Allah) and other devotional duties. Islam teaches us how to attain the virtues and how to give up bad habits because both good and bad grow in the man according to his upbringing, education and environment.

A human being has natural desires: food, sleep and sex being the three primary ones. He has also natural emotions: sorrow, happiness, love, fear, disgust and avarice etc. Islam doesn’t recommend the complete abrogation of these impulses but offers a method of controlling them through religious education and discipline.

The prohibition of eating pork in Islam is relevant in this context. There is a saying in English that “a man becomes what he eats.” According to physicians and medical experts, pork is a harmful diet. Consumption of swine-flesh creates lowliness in character and destroys moral and spiritual faculties in a man.

Body & Soul
The life of a man is a compound of body and soul. Anything, which is harmful for the body, hurts the soul as well. Consumption of swine-flesh reduces the feeling of shame and as such the standard of modesty. Those nations, which consume pork habitually, have a low standard of morality with the result that virginity, chastity and bashfulness are becoming a thing of the past in Europe today. The number of unwed mothers is on the increase despite the use of pills and other contraceptives.

According to a report, 60 to 70% girls in Sweden become mothers before marriage. The formula of “skin to skin is no sin” is having its toll but there is hardly any feeling of shame and remorse over the end-result. Since the European nations have become addicted to wine and pork, sexual freedom with all its attendant evils has got ingrained in their culture. Consequently, homosexuality has been legalised by the British Parliament. (more…)
