Operating Procedure of LCD

Operating procedure of LCD is very easy. There are 4 steps to make it works. The first, make sure that the source power of electricity has been supplied to the LCD. The second, press the power button which is present on the remote or on the upper-side of the LDC casing. The third, make sure that the cable connector between computer and LCD has been connected. The fourth, try it and be patient.

 Freon and carbon monoxide

Freon and carbon monoxide which all of them are chemical substance have many negative effects for the Earth and the organism inside the Earth itself. In this case, Freon plays important roles in weakening the ozone layer, reducing the water quality, and increasing the geothermal. It is true that, Freon, which had been named as Chlorofluorocarbon (CFC) by IUPAC organization, weakens the ozone layer. It is caused by the carbon and the other chemical substances inside Freon (chlorofluorocarbon) react with ozone, which is also known as Trioxide or O3. That reaction decreases the amount of ozone in the atmosphere; as a result, the ultraviolet ray (UV ray) which is brought by sunlight and the one of the causes of skin diseases such as contusion or cancer skin is not filtered optimally. Furthermore, the UV ray also disturbs the photosynthesis process of plants. In other words, it will kill the plants. Ozone also has other functions besides filtering the UV ray such as disinfectant, detoxification, and deodorant of air and water. Of course, a weakening of ozone layer also increases the amount of bacteria and toxin in the water and the air. Equally important, Freon substance also increases the geothermal. Consequently, it makes the ice which is placed in the North Pole reverts into their base form; that is water. It is the reason why the quantity of sea water increases. Geothermal not only increases the quantity of sea water but also increases the temperature of the air which contributes the unpleasant atmosphere in doing our activities. Next, Carbon monoxide, which is represented by symbol CO, disturbs our respiration system, decreases the blood quality, and causes the death. When the human sniff the carbon monoxide substance, it will be trapped inside the lungs. And then, the trapped substance cannot be processed because the space which supposes to be filled by oxygen is replaced by that dangerous substance. As a result, the lungs cannot work properly. Besides, that trapped substance will be chained by the blood; then, the blood which contains the unhealthy and poisonous substance will be transferred to the all parts of human body through the heart. So, the heart will stop doing its duty as a pump of blood (death) if someone sniffs the carbon monoxide in a large amount. In conclusion, although those both of chemical substances have many negative impacts, we still can reduce those impacts if we are more prudent in guarding and caring the earth.


Freon and Carbon Monoxide


Freon and carbon monoxide are chemical substance. We can find all of them only in the air. Freon or chlorofluorocarbon (CFC) is a colorless and an odorless gas. The study of the CFC was begun in 1890s by the Belgian scientist. The CFC consists of 4 chemical substance; those are carbon, chlorine, hydrogen, and fluorine. All of those substances will not give a dangerous impact as long as they do not react to another chemical substance. In addition, those four elements of CFC compiler also have different characteristics. First, carbon which is represented by the symbol C has solid form; the atomic weight is 12.01, and the atomic number is 6. Second, chlorine which is represented by the symbol Cl has gas form; the atomic weight is 35.45, and the atomic number is 17. Third, hydrogen which is represented by the symbol H has gas forms; the atomic weight is 1.008, and the atomic number is 1. The last, fluorine which is represented by symbol F has gas form; atomic weight is 19, and the atomic number is 9. Equally important, CFC substance is produced to give cold effect in the refrigerator or air conditioner (AC), and it is also produced to give the additional pressure inside the perfume, hairspray, or pilok (spray paint).Of course, those help us. But, CFC also harms the Earth and the organism inside the Earth such as weakening of ozone layer, decrease of the water quality, and raising the geothermal. At this point, Carbon monoxide which the molecular formula is CO is a combination of 2 elements; those are carbon and oxygen substance. Those 2 CFC compilers have different characteristics. I have already explained about carbon in the previous sentences. So, I will explain the next CFC compiler. Oxygen, which is represented by the symbol O, has gas form; the atomic weight is 16.00, and the atomic number is 8. Also, it is a friendly chemical, needed by the organism of the earth, and the reason why the organism can survive. Carbon monoxide is produced by the imperfect combustion of petroleum which can be founded in an automobile, factory, and motorcycle engine. Carbon monoxide disturbs our respiration, decreases the quality of the blood, and causes the death. Although carbon monoxide has many negative effects, it also gives advantage contribution in the technological communication. Specifically, carbon monoxide reflects the electromagnetic signal into the receivers or transmitters, and it is faster than the atmosphere do. In conclusion, both Freon substance and carbon monoxide substance have different specifications, advantages, and disadvantages.


The Guitar


I think guitar is the hardest instrument to be played in a rock or metal music. These are my reasons. First, there are 6 strings and 24 fingerboards on the guitar. As a result, it produces more than 120 notes, and each note also has different octave. When we want to play a rock or metal music, we need a chord. We just need to push two until six strings on the different fingerboards. For example, we must push the first string on the third fret (G note), the second string on fifth fret (E note), the third string on the fifth fret (C note), the forth string on the fifth fret (G note), the fifth string in third fret(C note), and the sixth string on the third fret to (G note) produce the chord C. So, the mastery of 120 notes of guitar is an important requirement to play guitar in a rock or metal music. In contrast, another instrument of music such as bass which has 4 strings and 24 fingerboards only has 96 notes. Besides, the chord of bass is quietly simple; it consists only 1 string. If guitar has more than 120 notes, it is different with drum which does not has notes at all. As a result, It is easier to play. Second, the guitar has 6 common techniques such as hammer-on, pull-of, bend, slide, vibrato, and sweep-picking. Those techniques must apply in playing metal or rock music because the characteristic of metal or rock music is fast and hard tempo. All of those techniques are extremely difficult, and only the expert can apply those techniques. Last, the pliability of the fingers is needed in a rock or metal music. It is because the fingers must adapt to the speed of those music. In other words, the fingers must be capable to make 3 different sounds in a one beat, and move from third string to one string also in a one beat. The minimum year needed to flex the fingers is 2 years. In conclusion, the pliability of finger, mastery of 6 techniques, and mastery of 120 notes in the guitar are the aspect caused the guitar is hard to be played. But, those aspects are still capable to learn.

The Comments About the Birth Place

Someone must has comments for the place where she was born. There are 4 women who give their comment about their birth place. First, Alison who was born in Belfast, Nothern Island gives her comments. She said that Belfast has lovely people who who don't doubt to share a laugh. She lived in Belfast for 4 years until she moved to Scotland. She recomended to visit the place which Titanic was built and Elbert Clock. Second, Jennifer from Erie, USA gives a comment about her birth place. She lived in there for 17 years. The weather is warm and very hot in the sunny. She loves her friend in there. Third, Katheleen from Triniad, Carribean Island turns.She lived there from her childhood until teenager period. The weather in there is pretty hot. Triniad has beaches which have pretty weather to snorkle, swim, and dive. Those are the comment about their birth place. In the end, one to others have different comments.


The Horrible Day


The mas has experienced an unforgetable moment in 2 days. In the first day, he felt down from a stage where he did his duty as a chairman of the show. Then, the ambulance which brought the man did an illegal manuver; so that, the man felt unpleasant. In addition, the man arrived in the hospital without guardian; instead, he comes in by himself in the painful way. In the second day, his suffering raised and more painful than the day before. he had an unpleasant treatment from the nurse, doctor, and the hospital taker such as putting the thermometer into the mouth unslowly, waking up unsoftly, cleaning the face hardly, and putting injection fast. So, it was the horrible days for him.
