Pneumonia, The Toddler Main Killer
Posted on | November 8, 2009 | No Comments
Busy prevent the spread of with HIV / AIDS, tuberculosis, and influenza A H1N1 made the world off guard. Slowly but surely, pneumonia (pneumonia acute) continues claimed the lives of children.
According to UNICEF and WHO, pneumonia is the number one child killer who has been forgotten (forgotten major killer of children). Whereas, it caused higher mortality when compared with total deaths from AIDS, malaria, and measles.
From 9 million deaths in children under five years (toddler) per year in the world, more than 2 million of them die because of pneumonia. Means, 1 in 5 children who die globally due to bacterial or viral pneumonia.
Causes
Most of the causes of pneumonia are microorganisms (viruses, bacteria). Respiratory virus, or RSV syncital most common cause of pneumonia, especially in infants. The resulting symptoms vary, indicating atypical pneumonia infection. Read more

Posted on | November 7, 2009 | No Comments
Chances are 1 in 300 if the 400-meter sized asteroid will hit Earth in the year 2029 but may be missed if the scientists managed to obtain additional data about its orbit.
Until now the asteroid is named Asteroid 2004 MN4 is rather difficult to observe. “The Torino Scale Collision strength used by astronomers about the possibility of collision with Earth, the asteroid was scored 2 out of 10″, said Donald Yeomans of the program manager of the Near Earth Object part of the propulsion system NASA Laboratory in Pasadena.
But there is no asteroid has ever scored more than one. On the day Friday, April 13, 2029, “we can not predict it,” said Yeoman again. The asteroid was discovered first time in June and look again at this month.
If this asteroid hit the Earth at sea would cause a tsunami, while on the mainland would cause great damage. Potential size of the 600 megaton explosion.
According to the present Yeoman asteroids that takes less than a year to evolve around the Sun has been observed from 40th place on Earth. First kalinua at Kitt Peak Observatory and this month from Australia and New Zealand.

Playback recorded conversations between Anggodo Widjojo with various parties have revealed the occurrence of engineering criminalization of KPK. In fact, the effect of playing recordings of conversations that wiretapping is much greater. This tape has forced Deputy Attorney General, AH Ritonga and Police Headquarters Kabareskrim, Komjen Susno Duadji resign, because his name was mentioned a lot in conversation Anggodo.
Many people wonder how it actually intercepts conducted, and how well the signs of bugged phone. Moreover, tapping not only the officials, but it can be done to anyone.
Actually, not too difficult to identify whether our phone was bugged people. Here are some simple ways to recognize the symptoms.
- If your phone battery drained faster when rarely used, you should be suspicious. Therefore, a spy software (spyware) that is embedded in the phone, usually will send the information to the wire. This causes the phone battery will drain faster. Read more

Hands is the main medium for the transmission of germs that cause disease such as diarrhea and respiratory diseases. From various research, the risk of disease transmission can be reduced by an increase in the behavior of clean and healthy living, hygiene behavior, such as washing hands with soap. Wash hands with soap is one of the most effective way to prevent bird flu, swine flu, diarrhea and pneumonia. Each year, more than 3.5 million children can not live up to the age of 5 due to diarrhea and pneumonia. Unicef says washing hands, especially after contact with feces can reduce diarrheal diseases by more than 40%, and reduces respiratory infections by 30%. Read more
Laboratory Equipment Cleaning

Cleanliness of laboratory equipment, whether in the form of equipment or non-glass container glass such as polyethylene, polypropylene and Teflon, is a very fundamental part of laboratory activities and is an important element in quality assurance programs.
Attention to the cleanliness of these items should be improved and should be proportionate to the level of interest test, the required measurement accuracy and decreasing the concentration analit to be determined.
Each laboratory should establish adequate procedures for cleaning equipment and non-glass cups that are used in a variety of tests. If a particular test methodology requires a specific cleaning procedure, the procedure must be followed.
How to Clean General Laboratory Equipment
The process of cleaning must be done immediately after the equipment is used. Disposing of hazardous materials and corrosive cleaning equipment is cleaned before. Washing equipment must be manually or automatically using a suitable detergent to use. Read more
The Series of Earthquakes in Indonesia

Large-scale earthquake will knock down anything on earth that unsound and fragile. This phenomenon is not just demolish the building, but also makes landslides, broke, and ambles. Beyond that, an earthquake of the coast is also a potential cause tsunamis. That is a series of threats to the population in the earthquake-prone areas.
As long as the earth rotates, the movement of plates covering the earth and float on the magma will never stop. Between plates of collision or the crust is what causes earthquakes continue to occur after another all over the world.
When one location in the boundary layer of rocks collapsed due to the earth’s crust holding the pressure plate merapuh, rocks that would seek a new stable position. During this process will be a series of aftershocks, the main pascagempa. This can result in cracked buildings and fragile finally collapsed.
For earthquakes in Padang, 30 September, hack earthquake even hundreds of times before the incident. Since the earthquake in Aceh, December 26, 2004, Padang and surrounding areas are often hit by earthquakes scale 4 to 6 on the Richter scale. “The numbers in the hundreds,” said Sujabar, officials at the National Earthquake Center Meteorology, Climatology, and Geophysics.

Natural Gas Flow Measurement
Posted on | October 2, 2009 | 1 Comment
In the measurement of gas flow rate, there are several types of systems-meter (gauge) commonly used, among others:
1. Diaphragm Meter
2. Turbine Meter
3. Orifice Meter
4. Ultra Sonic Meter (USM)
Diaphragm Meter
Diaphragm Meter
Diaphragm meter is usually used to measure the gas consumed by households, small commercial firms and other consumers. With these tools necessary gas pressure and low flow rate. This tool is able to measure accurately the volumetric flow in the overall value and does not require any additional energy source (electricity). The problem faced only if the pressure is too low and is unable to rotate or move the recorder, which should have a minimum pressure for operation. Maximum working pressure of about 1000 mmH2O.
This tool consists of the machine:
- Diaphragm that divides the two parts with 4 drive gas flow will move the field diaphragm, forwarded to the shaft (lever) and play the recorder (counter). Style that encourages the flow of gas turns diaphragm field, resulting in movements that rotate around the needle recorder. Materials used for the diaphragm of oil resistant rubber imitation.

How to Use Planimeter in Natural Gas Flow Measurement
Posted on | September 28, 2009 | No Comments
Orifice meters used to measure the volume or flow rate of natural gas, in addition to using computer flow units as a means of output data, also prepared a back up facility Chart Recorder. This chart used to record fluctuations Static Pressure (P), Temperature (T), and Differential Pressure (DP) for 24 hours. To be able to know the amount of each transmitter used a planimeter aids. This tool is more commonly used as a tool to calculate the area of a region on a map.
Chart Recorder
Flow / Chart Recorder is used as a backup tool for electronic flow measurement computers on meter system, both in customers and with the supplier (off-take). Chart Recorder is commonly used brand of ITT Barton or Foxboro.
These types of recorders are distinguished on the basis of the number of pen used, some systems that use charts include:
- Recorder pens 2 (P + DP)
- Recorder pens 3 (P (blue) + DP (black) + T (red))
where:
P: Pressure
DP: Differential Pressure
T: Temperature Read more
