Ultrasonic sound technology

One system offered to drive the rats are ultrasonic sound technology. Ultrasonic sound technology is the technology by utilizing high frequency ultrasonic sound of voices, i.e. 35 000 Hz. Sound frequency can only be heard by the order rodentia animals, including rats. The voice could not be heard by humans. Human can only hear sounds with frequencies Hz 20000-25000.

Ultrasonic sound may cause discomfort in the rat. It works like human beings who put her ear to the siren sounded very loud. Rats will feel afraid, can not adjust, and certainly do not feel comfortable with ultrasonic sound generated. This tool also uses generator that can remove ultrasonic sound louder and changes making increasingly disrupted mice.

Electromagnetic Waves

The second system is to use electromagnetic waves. Electromagnetic waves are produced by utilizing power cables power that lay behind the walls of your home. With such capacity, the product has become a tool to drive the giant rat. It works the same way as when you call. When speaking, your voice will be delivered via telephone lines at a certain frequency. Wave utilizing electromagnetic power cables to transmit signals through the cable changes, which can disrupt the nervous system of mice.

Bangladesh, Indonesia, and Iran are the three countries belonging to the most vulnerable to natural disasters. This statement is a conclusion of a study. This was announced Thursday. Duo Asian giants, China and India, participate in a list of 15 countries of 229 that included risky ‘extreme’. Index of Natural Disasters (Natural Disasters Risk Index / DRI) were prepared by a British consulting firm risk, Maplecroft, based on disasters nature that have occurred since 1980 until 2010.

There are several kinds of indicators, including the frequency of occurrence, the total death toll, and its comparison with a population of a country. In the list these natural disasters are earthquakes, volcanic eruptions, tsunamis, hurricanes, floods, droughts, landslides, heat waves and epidemics.

"Poverty is an important factor in countries whose frequency and impact of severe natural disasters," says environmental analyst Maplecroft, Anna Moss.

"Infrastructure bad, plus the population density in high risk areas such as plains, riverbanks, high cliffs, continue to increase the likelihood of victims. "

The NDRI research, the death toll from Bangladesh reached 191 thousand people from natural disasters over the last 30 years. Indonesia also has nearly equal numbers of victims, mostly caused by the tsunami in December 2004. While in Iran, the greatest vulnerability to disasters are earthquakes, which has caused 74 deaths of thousands of lives.

Magnesium is one of the essential minerals required by the body. Magnesium deficiency can lead to various disorders. Here is a discussion about the causes of magnesium deficiency and how it can be treated with dietary intake and magnesium supplements. Magnesium is an important mineral that is needed by every cell in the human body. About half of the magnesium stores in the body are found in the cells of the body’s organs and tissues, and the other half is found in our bones where it occurs in combination with phosphorus and calcium. Magnesium occurs only in 1 percent concentration in the blood. The human body has to work very hard in order to keep the magnesium levels in the blood constant. Magnesium is required by the body to carry out various biochemical functions such as enzyme activity.

Magnesium deficiency in the body can cause the following: loss of appetite; disorientation; confusion; psychotic behavior; depression; tremors; convulsions; numbness, tingling, and cramps in the muscles; vasodilation, or widening of the blood vessels; coronary spasms; abnormal heart rhythms; seizures; and irritability of the nervous system.

How Much Magnesium Do We Require?

Remarkable achievements inscribed by Alexander Randy Angianto as the only youngest graduates with a degree in medicine (S. Go) from the Faculty of Medicine, University of Gajah Mada (UGM).
