Various benefits behind the Nuclear Risk

Diposting oleh edinfo di 22.08 | 0 komentar

Though worried by the world community made Fukushima Daiichi nuclear power plant accident, Japan, in fact nuclear has a lot of benefit in various fields such as food and agriculture, health, hydrology, and industry.

Company In Indonesia there are many small, medium and large, ask for assistance Applications Center for Isotope and Radiation Technology National Atomic Energy Agency (Batan PATIR). There is a company that asked for smoked fish are sterilized by radiation isotope so that the fish free of fungi and mold so durable without preservative. There is a geothermal company that asked for help tracking network of underground steam wells to know its potential, said the head PATIR, Dr. Zainal Abidin Dipl. Geo. In the field of health, nuclear radiation is used to detect diseases or abnormalities in addition to network with tracer techniques such as in cancer treatment. The same technique to examine the increasing weight of beef cattle with food and finding out what is most responsible enzymes in the digestive process and affect the increase in weight of cattle, said zainal.
Tracer technique was also used in oil and gas industry, geothermal, sugar, fertilizer and cement. Its use, among others, for pipeline leak testing and processing machine quickly and accurately without dismantling the construction so that save cost and time. Some private companies have been using radiation isotope for various applications including sterilization of food for free from mold and mildew. The same way is also used for sterilization of disposable syringes.
In the tire company, radioisotope power tie molecules make better rubber. The same is done for rubber gloves. In agriculture, various rice varieties resulting from the process of nuclear irradiation with gamma ray irradiation, rice seed was forced to mutate. Seeds which have undergone mutation and selection in plant and carried out according to the desired properties, and plants that do not contain any guarantee as for the nuclear residue.

United States Vice President Al Gore during his visit to Indonesia some time ago said that Indonesia is very potential and opportunity to become global giants in the field of geothermal energy. As it is known that geothermal heat is energy contained in hot water, steam hydrothermal, and rocks that are in the bowels of the earth. Countries that have this potential can be seen from the character who is surrounded by volcanoes. Al Gore said that geothermal energy is the solution to save money and reduce carbon dioxide emissions. Climate change has become a real threat to the world with increasing carbon dioxide emissions cause the greenhouse effect, and Indonesia is the largest contributor to CO2 emissions second only to Brazil with a total of 1.46 billion tons according to data from World Source Institute in Washington DC in 2010. Interestingly most of the carbon emissions generated from the forestry sector. To reduce carbon emissions many countries around the world began to reduce use of fossil fuels and replacing them with environmentally friendly energy. Geological Survey recorded the geothermal energy in Indonesia is one of the largest in the world that is equivalent to 28,000 MW in 2009, the number was equivalent to 30% of the world's geothermal potential. Unfortunately, with the potential for the bari 1189 MW are successfully used for electricity generation. Compare with the U.S. that has produced electrical energy is more than 4000 MW, or the Philippines produces more than 2000 MW.
Potential geothermal resources in Indonesia are spread in eastern Indonesia such as NTB <NTT, Maluku, North Maluku, Sulawesi, which has electrical energy depends on Diesel Power Plant (PLTD) in which capacity <5 MW, but if the heat can be substituted with earth will be able to save approximately 450,000 liters per year or equivalent to Rp. 2.9 Trillion per year. The government indeed has pioneered the development of geothermal energy projects through PT. Pertamina Geothermal Energy (PGE), but its management is still in small scale and not directly. In addition the government will also conduct a number of measures to support the development of geothermal energy in Indonesia, including the signing between PLN and PGE projects in cooperation geothermal, open investment of geothermal projects, and held talks with World Bank financing of projects related to these environmentally friendly energy . To speed up the process of administration of geothermal energy development projects, Vice President Boediono also asked the head of the existing areas of work in the region PGE to simplify licensing and other issues related to land use, because geothermal energy is environmentally friendly that the user needs to be intensified

It turned out that the need for drinking not only appear when a person feels thirsty but not hungry any time someone takes a drink, because when people actually feel thirsty person is already experiencing mild dehydration so says the faculty of Faculty of Medicine, University of Indonesia DR. dr Dr.Saptawati Bardosono MSc.
About 70% of the human body consists of water, so lack of water can be harmful to the body. Water is a nutrient essential for life, all systems in the body depends on water. Described by Dr.Saptawati lack of water in the body can cause dehydration that is when the water in the body is not sufficient to perform normal work functions. Even mild dehydration will cause a disruption in the body such as the level of system performance, cognitive and mood. Results of recent studies conducted in 2010 by the hydration of the world's expert Lawrence E. Armstrong PhD and R. Harris Lieberman PhD who is an expert on neuro cognition from the United States. The study was divided into two parts. The first study involved 26 male and 25 female healthy adults with age range 20-23 years. In the study subjects were examined by performing a treadmill as much as 3 x 40 minutes at 28 C (room temperature work) and asked to complete the cognitive tests, the results of research indicate dehydration of 1.5% in men and mengngat cause difficulty concentrating, tired and tense. While women are more negatively affected by rapid dehydration that is only 1.3% dehydration can cause fatigue, irritability confusion, drowsiness, loss of concentration, dizziness and difficulty in completing tasks. This study is a great use of sophisticated technology that checks dehydration on ordinary people rather than athletes at room temperature everyday workplace. While the second study conducted on 20 healthy adult women who drink water as much as 2 to 3 liters a day, they were asked to fast for 23 hours and perform cognitive tests, study results show the same thing with the first study. Dehydration significantly causing confusion and fatigue in addition to drowsiness, headache, and disturbed emotions quickly. Even got a mild disturbance in finishing the job done everyday. Decline to 2% dehydration can affect short-term memory and ability to concentrate and learn.

Smoking May Increase Bad Cholesterol Levels

Smoking for some people has become a lifestyle, life feels empty without the smoke, the work becomes less enthusiasm, lack of concentration, and less social. Although some people ignore the danger of smoking but the dangers of smoking should continue echoed both through the media and scientific research in the field of health.
A recent study conducted by Dr. Adam Gepner from the University of Wisconsin School0f Medicine and Public Health in Madison United States revealed that smoking can raise levels of bad cholesterol (LDL) and lowers good cholesterol (HDL) Cholesterol is a fat yellow, produced in the liver and has several functions between another to make sex hormones that are important to the development and function of sexual organs, adrenal cortex hormones that are important for metabolism and salt balance in the body, Vitamin D to absorb calcium in the body and bile salts that help the intestines to absorb fat. HDL cholesterol carries less and capable of carrying excess bad cholesterol in the arteries to be discarded, while LDL is the bad cholesterol that tends to settle in the arteries.
Tests carried out on 1500 smokers in which each participant smoked on average 21 cigarettes per day. After one year conducted smoking cessation, of 334 respondents (36%) who stopped smoking found that levels of HDL cholesterol in the blood increased by about 5% or 2.4 mg / dL HDL cholesterol. Another effect showed that weight gain occurred an average of 10 pounds after quitting smoking. While weight gain can affect cholesterol levels as well, both good and evil and a healthy diet and regular exercise may be used as a means to overcome this weight problem. Researchers also noted that it is unclear how the process of quitting smoking can affect cholesterol levels, could be due to the destruction of proteins that function to control cholesterol levels. Whatever happens to the visible benefits of quitting smoking is a healthy heart

On Nuclear Power cleavage reaction of atomic nuclei in a nuclear reactor. This reaction produces some isotopes such as Xenon-133, krypton-85, and Iodine-131 with a release of energy. This decay process also produces radioactive substances such as alpha rays, beta and gamma. Among the three most dangerous gamma radiation. Type of radioisotopes commonly detected in gamma radiation is cobalt-60, cesium-137, cadmium-109, sodium-22, manganese-54, barium-133 and cobalt-57.

Leakage of nuclear reactors can release radioactive substances into the environment. The case of the 1996 Chernobyl release of radioactive material is great especially radioisotopes of cesium and iodine that contaminate water, food, and air. Report the impact of the explosion at Chernobyl released World Health Organization (WHO) declared around 4000 thyroid cancer cases occur in Belarus in 1990-2002, other than that reported increased cases of leukemia (blood cancer).

Chairman of the Nuclear Energy Supervisory Agency (Bapeten) As Natio Lasman said, a person can be exposed to radioactive substances on the outside and inside the body. Because the radioactive substance can be entered during breathing, eating, drinking, or through wounds. Contamination can occur in sea water used as coolant. Radioactive particles can be ingested fish and will go into the human body which consume fish. Radioactive particles could be flown wind and contaminate soil, water and air around.

Radiologist who is also Chairman of the Executive Board of the Indonesian Doctors Association (IDI), Prijo Sidipratomo say, so get into the body, radioactive isotopes will be distributed throughout the body. Most settle in the organ or tissue, partly out through the urine, feces, and sweat. Radioactive contaminants can accumulate in body organs according to the nature of physics and chemistry. If the body exposed to doses of 350-450 rem in quick time, there is a 50% risk of death within 30 days. Dose of 100 rem in a long time cause cell damage that can not be restored. Prijo say, cell damage can impair organ function. Depending on which part of contaminated radioactive substances. If exposed to the gonads (testicles or ovaries) may occur sterility. Moreover, it can happen mutation that causes cancer cells to organs and blood. The organs that are sensitive to radiation exposure is the thyroid gland, intestines, kidneys, spleen and bone marrow. Radioactive exposure in pregnant women may interfere with fetal growth, ie irregularities in the process of organ growth. Exposure in children was also dangerous since the body cells more vulnerable children. In addition, the child's body area is smaller than adults, so even though the amount of exposure to the same but the dose becomes greater.

To reduce the radioactive substance which has entered the body's effort to reduce absorption in the digestive tract, inhibiting the deposition in the organs of the body, dilution, change the chemical properties of materials and the use of chelate techniques.

Plants gandarusa for Men Contraception

Diposting oleh edinfo di 03.25 | 0 komentar

The findings on the benefits of this gandarusa leaf is Eko Bambang Prajogo Wardojo a researcher and lecturer at the Department Farmakognisi and Phytochemicals Faculty of Pharmacy, Airlangga University, Surabaya, Indonesia. Contraceptive tablet has been clinically tested on humans and obtained a patent on June 12, 2008. On December 14, 2010, the National Family Planning Coordinating Board launched a contraceptive tablet is to be mass produced with PT. Indofarma as producers.

Previous Bambang tablet clinically tested extract gandarusa (Justicia Genderusa), involving 36 male volunteers who have a spouse and both fertile. The results of herbal tablets that proved to weaken the sperm cells periodically. This means that the tablet was safe because they do not spay man permanently. To prepare for mass production will be a clinical trial with 350 male volunteers who already has a wife and both were fertile. Other targets to be achieved is the active compound gandarusa grown faster in spay sperm. The target can be active at work after 30 minutes of drinking, such as conventional medicines.

Inspiration comes from the use of leaf gandarusa ethnobotany research results of researchers from Gadjah Mada University in Yogyakarta on the tradition of marriage with a dowry of less than a tribe in Papua. In the tradition of the applicable requirements for male applicants who brought her dowry is less than expected, still allowed to marry the girl but can not impregnate his wife prior to settle the dowry required. To avoid pregnancy, the men were fed leaves gandarusa. When the dowry paid off before the man can impregnate his wife.

With the presence of leaf gandarusa expected to bridge the gap between traditional knowledge with modern science that benefits in dealing with population explosion.

Without Bee, No Life

Diposting oleh edinfo di 03.42 | 0 komentar

If bee loss from this world, the human just can life for four years. If there are no pollination, there are no plant, there are no animals,there are no human (Albert Einstein).
This statement maybe is make simple the problem  too but actually very logic , without bees,no pollination, at least the process will be reduced drastic. There are no pollination, there are no food. How the human life without food ?
There are some another ways to help pollination but bee is the best. at least 90% pollination spermatophyta plant is helped by bee,said Warsito, the specialist of insect The Research Biology Centre from The Organization Science Indonesia (LIPI). The world now threatened loss of bees, one of phenomena newest is to occur colony collapse disorder (CCD). In one year since reported at 2007, CCD have kill a third of bees (Apis Mellifera) in  United States and killed million of colony in the world (Alison Benjamin and Brian Mc.Callum in a World without Bees,2008). at 2009, the government United States report occur degradation Bee colony up to 29%. This moment occur in Europe, Japan, China, and another states include Indonesia.
The syndication of CCD can known from honey comb which leaved the worker Bees and rest the Queen and their baby get hunger and then died. Some researcher suppose CCD caused by losing ability to navigate because the change of climate so that can't find the way back to honey comb. Another reason is pesticide effect 
and environment change.
Follow the researcher of Bee from P2 Biology LIPI, Sih Kahono, the character of Bee have formed since long time become in confusion because the rhythm of nature is change. Although each animal have the adaptation  but not all of them get it. at Gombong, Central of Java Indonesia, the gardener must help the pollination of Melon by manual because Bangbara Bee (Xycocopa spp) had rare said Kahono. This Phenomena remember in situation at south Sichuan China when thousand of people  get payment  to help pollination of peer. So From Bee, we can read the climate change really present and threat life of human as Einstein's Statement.
