Why ants would pause if met / met with other ants?. Ants that look "pitted head" when meeting it is actually being communicated. T.C. Schneirla, a researcher at New York University, had conducted experiments with ants. He took an ant and then put in place of food. Another ant put in place that contains enemy ants. Then the second ant behavior is observed especially when met with his friends on the street.
From that research, Schneirla concluded that chemicals released from food or from enemy ants ants stick to it. When meeting with his ants, the ants would greet each other (touching). Well, here's to greet each of the chemicals the ants will tell her (via antenna on the head ant) whether there is food in the surrounding environment or enemy.

SOHC VS DOHC
Differences DOHC VS SOHC
DOHC stands for Double Overhead Camshaft (as an alternative to the SOHC engine type). Layout engine uses two back (camshaft as) on top of the engine block. It also means that the engines are DOHC V 4 camshafts because there are two blocks that make it easier for the machine manufacturer implements 4 valves per cylinder. Most also brings propeller DOHC engine (RPM) is higher.
Better layout optimizes valve setup that maximizes engine performance as well. But its shortcomings, the weight will increase, more expensive, and more complicated. Also more parts to play two back.
The main reason to use a DOHC valve to add more on each cylinder. (But) if SOHC allows the use of 4 valves per cylinder (as in MX or Thundy 250), the DOHC is no longer everything. Especially with a heavier weight.
In short, SOHC 16 valve has better torque at low rpm because it is lighter (rotating machine) and vice versa DOHC engine produces more torque due to the weight lower. But in at high speed, 16 valve DOHC engine torque will be better. That's the trade-offs. When the spigot amount equal, SOHC has better low-end torque while DOHC has better top-end power is higher.
Another advantage, easier to apply tenologi DOHC variable valve timing (VVT) and ditune-up easier. If you intend to use a back-profile racing on the DOHC, lobe profiles can be optimized for easier fiddling add modifiers in a separate state.
Why need more valve? Why you do not make each one suction valve and discard it? Of course not. Larger valve would be heavier and would be very difficult to control at high engine speed. Per valve must be rigid, which means also the extra energy needed to withstand the pressure (motion) valve. Useless, is not it!
Also at low engine propeller, the large valve suction velocity becomes lower. Simply this: the power of pressure on a hole that big is definitely smaller than the holes smaller. Because the suction velocity decreases, low torque and engine movement also weakened.
Although two smaller valve would weigh 1 large valve, and with the addition of the trigger valve (rocker arm) and by which means a little heavier, but all that means nothing compared to decreasing the burden on the process of opening and closing the valve. So, more valves per cylinder is more profitable?
Let's compare a Nissan VG30E versus VG30DE. Both 3.000cc with electronic fuel injection, but that the 2 valve SOHC and DOHC 4 valve latter per cylinder. Consider the diagrams below. Look at the same RPM at low speed, but 2 valves per cylinder has reached its peak and had to change gears, while the twincam 4 valve per cylinder continues to add energy at its peak powerband. Powerband (power distribution) is also longer. But remember, this graph to determine the different 2-valve and 4-valves, not to compare the SOHC vs DOHC.
Show SOHC
In conclusion, SOHC has better torque down lap, while the opposite DOHC (peak power and energy distribution of the maximum length of time). 4 valves per cylinder better than 2 valves per cylinder, 4 valves either the SOHC or DOHC dipanceng on.

Game Console I Have Played Until Now
1. SNES
The Super Nintendo Entertainment System (also known as the
Super NES, SNES[b] or Super Nintendo) is a 16-bit video game console developed
by Nintendo that was released in 1990 in Japan, 1991 in North America, 1992 in
Europe and Australasia(Oceania), and South America in 1993. In Japan, the
system is called the Super Famicom (スーパーファミコン Sūpā Famikon?, officially
adopting the abbreviated name of its predecessor, the Family Computer), or SFC
for short. In South Korea, it is known as theSuper Comboy (슈퍼 컴보이) and was distributed by Hyundai
Electronics. Although each version is essentially the same, several forms of
regional lockout prevent the different versions from being compatible with one
another.
The Super Nintendo Entertainment System is Nintendo's second
home console, following the Nintendo Entertainment System (NES). The console
introduced advanced graphics and sound capabilities compared with other
consoles at the time. Additionally, development of a variety of enhancement
chips (which were integrated on game circuit boards) helped to keep it
competitive in the marketplace. While crude three-dimensional graphics had
rarely been seen before on home consoles,[11] utilizing the Super FX chip
beginning with Star Fox in 1993,[12] the SNES was able to run games with
smoother and more detailed three-dimensional graphics than was previously
possible. This sparked more widespread interest in polygon graphics in the
industry, helping to usher in 3D graphics as seen in the fifth generation of
video game consoles.[13]

Smartphone Most Vulnerable to Virus Attacks
Various security vendors try to predict trends in cyber security in 2013 . Well, for Eset , there are 4 things to watch out for is malware on smartphones , Botnets , cloud computing security , and information leakage .
Eset predict there will be a significant increase in mobile malware and its variants , the spread of malware via the Internet will also increase .
Meanwhile back botnets will rise , and the attack will lead to cloud computing will lead to leakage of information on cloud computing .
Significant improvement occurred in mobile malware during the year 2012 , so it is considered as the most ' sexy ' to be attacked . Which monitored many malicious programs that are developed specifically to attack the Android market that we know very soaring .
The rebound also trigger the emergence of malware that make such devices as the target .
Juniper Research says an independent research institute , in 2013 is estimated to access banking services conducted of smartphone devices will reach about 530 million users .

Survey: Electric Cars Not Attractive in Indonesia
Although the electric -powered vehicle is regarded as future vehicles , most of the riders were still not interested in buying an electric car . Only a small portion motorists are interested in buying it .
It was revealed in a survey performed by the Indiana University School of Public and Environmental Affairs in 21 major cities in the United States .
The survey involved 2,300 adults in the fall of last year . And even though the survey was conducted last year , the researchers considered the results of these studies are still relevant to the present because not much has changed in the electric car industry this year .
Currently the three most popular in the world of electric cars , the Nissan LEAF and the Chevrolet Volt and Mitsubishi i - MiEV still have no significant sales . Both brands were also known to have revised their targets because the sales are not as expected .

How to Make Pure Salt From Sea Water
Indonesia as a maritime nation , clearly have very much natural wealth . However , all marine resources in Indonesia , not maximal and optimal management . A very simple example is the natural wealth of the sea water itself.
Although Indonesia is Indonesia is a maritime country , but still there are people who get mumps , the disease occurs due to lack of yodium.walaupun not much . Iodine itself is usually found in salt content .
Therefore , in this occasion we will discuss in a simple purely to make salt from sea water .
To make salt from sea water , does not require modern equipment . In fact , if there is no equipment memadaipun , we can make on the sea shore sendiri.langkah - step in making salt from sea water is :
1 . If you do not have land or a place to make and want to make it on the beach , then the first thing to do is to clean up the beach that will be used to make salt from the bins , let's say there is trash around the beach area .
2 . If we have a place or land to be used to make the necessary salt is first prepared to make cans filled with sand and blame one corner we give an opening to the sea is through a refining stage .
3 . After all the media is ready , then the step is inserting beriktnya seawater slowly into a vat containing sea sand . Then , desalination of sea sand vat collected into a bucket .
4 . The next step is to pour the water into the distillation shaped box but the length , but the length of the box can be adjusted with our wishes , our distilled water and then pour it into the box with a depth of 1 segment telunjuk.hal serve water to dry quickly when it dries .
5 . Then after the water is poured , then the last stage of drying under the hot rays matahari.Dalam drying process , the water will evaporate and low water levels due to evaporate , leaving room grains - grains of pure salt ready for harvest .
6 . The latter is to collect grain - grain of salt , to be further processed for use in accordance with our needs .
Thus a brief overview of the process of making a simple salt . Easy - hopefully pleasing and useful .
Nutrition in Catfish
Catfish or keli or catfish fishing , is a type of fish that live in fresh water . Catfish are easily recognizable because of his smooth , slightly flattened elongated , and has a " mustache " long , sticking out from around the mouth .
Lele , scientific , comprised of many species . Not surprisingly, when the catfish in the archipelago also has many local names . Among other things : fish prop ( West Sumatra ) , fish death ( Gayo and Acehnese ) , fish sibakut ( Karo ) , fish pintet ( South Kalimantan ) , wrasses ( Makassar ) , fish CEPI ( South Sulawesi ) , catfish or leachate ( Java middle ) or fish keli ( Malaysia ) .
In other countries known as Mali ( Africa ) ,ナマズ( Japan ) and鲇 形 目( China ) . In English called also catfish , siluroid , Mudfish and walking catfish . Scientific name , Clarias , chlaros derived from the Greek , meaning ' lively ' , ' strong ' , refers to the ability to survive and move beyond the water .

When Got Diare
Symptoms are diarrhea or diarrhea with watery stool frequency 4x or more a day , which is sometimes accompanied by :
gag
Board lethargic or weak
hot
No appetite
Blood and mucus in stools
Nausea and vomiting may precede diarrhea caused by viral infections . Infection can suddenly cause diarrhea , vomiting , bloody stools , fever , decreased appetite or lethargy .
Also, it can also experience abdominal pain and stomach cramps , and other symptoms such gejal - flu for example a slight fever , muscle pain or spasms , and headaches . Disruption of bacteria and parasites occasionally cause stool contains blood or high fever .

Quality Impressions of Indonesia TV
Can not deny that the quality of TV shows and movies in widescreen Indonesia is getting worse and not educate . This is because the station - Bolo tv or home - home production movies that simply chase ratings or popularity level impressions are not concerned with the weight of the broadcast program . We just take the example of a soap opera , soap opera now has become a public spectacle with improvised stories and educate not at all . Most soap has a story that makes no sense , such as the poor or the rich marry the person who has the power not clear , this is not educational. Klo ancient soap opera when I was a kid there just after 8 o'clock . This is because after the sunset call to prayer shows impressions that will appear only news , despite it boring but very educational and can be seen at any age .
Adventure Chasing Dreams Never Ended
My name is Dwi Purnomo , my friend used to call Dwi . I was born on March 20, 1991 , when the count is now at my age already 22 years old , age is not really fit anymore to play - play . But there are actually unique of deed birth . I have two certificates with different names , date , and place of birth are different . But as time goes by only one deed are in use , because it has 2 certificates is prohibited .
I live in a modest family , with the father and mother are still incomplete and a sister . Actually I have an older brother - young , but he has died at the age of 9 years . After the mother took me to a village in the district of Kediri precisely , in order for the departure of my brother's mother mengikhlaskan biased , but my father did not participate because of his work in Jakarta . When I was in elementary school I had to move - to move in the first Semper SDN 07 and SDN Ngasinan moved in and the last SDN Marinating 2 , and we settled in Calcutta until now . Then I went to junior high 16 Bekasi , when smp nothing too special so I just download an ordinary boy who bit nosy and somewhat lazy .
When I started learning smp riding a motorcycle , but I'm good at it fast motor vespa motorcycle that uses a coupling of the motorcycle . Finally the time came to an end with the regular smp . Then I went to SMAN 2 Bekasi . When I walked into class 1 Rohis extracurricular , curricular Rohis here is quite different than I thought. In this extracurricular besides the Koran and Tausyiah , but also another example of the unique field is taught how to play skateboard . After sma finished I went to college but did not immediately leave for a year , well actually this is not acceptable because the university - a state university .
