- Solder WICK: It is made ​​of crocheted copper wire is thin, their role to absorb the excess tin on the PCB

- OIL COOLING OR SIONGKA CAIR: Often used when the removal or installation of the IC.

- LIQUID CLEANING: It is classified as a liquid chemical that is often used to clean the PCH, the fluid is called the liquid IPA.

- Foam solder: the surface cleaning fluids, or that the eyes will always be clean solder

DANGER drugs on HEART

SAkAU

EFFECT OF DRUGS ON HEART (LIVER)Not common knowledge that the liver is the most vital organ in the body and is a central life. Heart is what distributes what is needed all the muscles such as glucose (sugar) and distribute what is needed throughout the organs of the body according to his needs. The human body is threatened died suddenly at any time, if we know that glucose is the source of heat and life in the body and that the liver is the organ in charge of distributing the body temperature.No doubt that damage to the liver (Liver) was more attacking alcohol addicts than people other than them. Comparison of patients with liver damage from alcohol addicts and non addicts alcohol is 1: 6 or 8. In Western countries can be said truthfully that the liver damage caused and the use of alcohol. So based on the results of research for 10 years consume alcohol can cause serious liver injury and even death.


 NEGATIVE EFFECT OF DRUGS ON THE NOSE, EAR, AND THROATAt the peak phase of drug use and addiction to the phase, the nose is the organ that first felt the impact. Influence of drugs directly on the nose because the nose is the gateway to all drug substances, particularly cocaine and heroin. Therefore, we see that the reaction and the influence of drug substances consumed through the nose was almost exactly with the reaction of substances in the consumption of drugs through injection. The use of heroin and cocaine continuously causing a hole in the nasal septum and damage in the nose which causes the formation of a thick skin on the nose when pecandunya want to be free from the influence of drugs. Heroin and cocaine also cause loss of smell which is then followed day with no ability to feel the taste of food. If that happens then heroin and cocaine addicts will continue to suffer from infection in respiratory organs, and then he felt the dryness in the throat, an infection in the throat and persistent cough.

EFFECT OF DRUGS IN THE BODY PRODUCTION OF ORGANSSome research and studies on women showed that drug use during pregnancy may cause birth of the baby is not in one piece or birth defects. In addition, men and women will lose fertility within a certain period of puberty, because the time was the period of physical growth and sexuality quickly.

THE DANGERS OF dRUGS

The DANGERS of dRUGS

 

Functional changes at an early stage may be felt as pleasure. because it can lead to dependence.
           Dependency that caused by drug abuse have varied levels, which simply can be split into 3 types of dependence.1.ketergantungan primary
   Ie when the nascent anxiety and depression.2.ketergantungan sistomatis
   Namely the emergence of negative traits of drug users, such as anti-social nature of symptoms (psychopaths), criminal, and just looking for self-indulgence.3.ketergantungan reactive
   Dependence that is based on curiosity and want to try.EFFECT OF DRUGS ON BLOOD -.Blood in the human body as much as eight percent and he has a large number of blood vessels and pengerasannya tugas.Penyempitan is the leading cause clots to the heart and blood clotting blood clotting otak.di American case is called "Number one killer".-. Drug addiction and narrowing of the BRAIN
             The brain is the most important organ in the human formation.
             Dr. fadhli priest, professor of nervous and mental diseases at the university medical school ainsyams said "virtually all elements in the drug has direct access in place - a place on the wall nerves.The first part terpengaruholeh drugs is an area that connects the two hemispheres of the brain between the right and left. Afterward, the driving organs in the body become affected. Inhalation of heroin in the first stage no more than a few milligrams, that is what produces euphoria (happiness that is not fair). Reaction heroin ranged from 6-12 hours.Some heavy heroin addicts there who eat as much as 3gram at once, and after he collapsed in the complications of the disease include diarrhea, excessive tears came out, his skin wrinkled, pain due to inflammation in the stomach, constriction of both pupils until he dies or becomes insane.Drug addicts will also suffer from a narrowing in breathing, severe constriction of both pupils, muscle weakness and excessive sweat that comes out of the body temperature increases. The disease in heroin addicts who enter through a syringe, often causing blood clots because of dirty syringes are never in the clear.-. EFFECT OF DRUGS ON THE VEIN CELLS AND NERVEThe brain can calculate the enormous amount of defeating even the most sophisticated computer capabilities. What is the effect of addictive drugs on the brain? Indeed terdri brain over millions of nerve cells that work day and night in a consistent manner. There are cells that tugaasnya speak. there is a duty to hear. There are cells whose job seeing and so forth. Drug addiction and how any kind will disrupt the brain and paralyze the day-to-day tasks. Henceforth, humans become slaves to the substances that cause destruction teersebut periodically emaciation and damage to the brain nerve cells. When the drug addict's brain to weaken, then it becomes like an animal without desire, her memory is reduced, tense, frantic, unproductive, stepped from the bad condition of the condition worse, and ends with death. Thus, the influence of drugs on the brain substance is twofold, namely:
An exciting2 soothingAnd both are very harmful to the brain.
