Polyester Manufacturing

Polyester fibers, the synthetic fibers, are long chain polymers derived from coal, air, water, and petroleum. They are formed through chemical reaction between an acid and alcohol. In this reaction, two or more molecules combine to make a large molecule whose structure repeats throughout its length. These molecules are very stable and strong. There are variations in the compositions and therefore in the properties of polyester fibers. Types of Polyester The polyester fibers are generally available in two varieties- PET (polyethylene terephthalate) and PCDT (poly-1, 4-cyclohexylene-dimethylene terephthalate). PET is the most common production. It is stronger than PCDT, while PCDT has more elasticity and resilience. PET can be used alone or blended with other fabrics for making wrinkle free and stain resistant clothing that can retain its shape. PCDT is more suitable for heavier applications, such as draperies and furniture coverings. Modifications can be introduced in each of these varieties for obtaining specific properties. PET Polyester For manufacturing PET Polyester, the main raw material is ethylene derived from petroleum. It is oxidized to produce a glycol monomer dihydric alcohol which is further combined with another monomer, terephthalic acid at a high temperature in a vacuum. Polymerization, the chemical process that produces the finished polyester, is done with the help of catalysts. The colorless molten polyester then flows from a slot in a vessel on to a casting wheel and takes shape of a ribbon as it cools to hardness. The polymer thus produced is then cut into very small chips, dried to remove all moisture and blended to make it uniform for getting it ready for spinning into yarn. PCDT Polyester This variation of polyester is made by condensing terephthalic acid with 1, 4-cyclohexane-dimethanol to form poly-1, 4-cyclohexylene-dimethylene terephthalate or the PCDT Polyester. As for PET Polyester, PCDT is processed for melt spinning. Spinning Polymer chips are melted at 500-518Â °F (260-270Â °C) to form a syrup-like solution. The molten polymer is then extruded through a spinneret and the filaments are subsequently drawn into the desired polyester fiber. Variations are introduced to obtain desired end results. Spinnerets having hole of different shapes such as round, trilobal, pentalobal, hexalobal or octalobal can be used for special effects like opacity, luster or its suppression, wicking, comfort or feel. Hollow fibers may be produced to make it lightweight and for providing greater cushioning or insulative properties. Crepe effect can be obtained through crimps. Certain additives may also be combined with the spinning solutions for specific properties. Delusterant can be added to make the fiber dull, a flame retardant may be added or Certain other antistatic substance may also be included. Drawing After extrusion from the spinneret, the fibers are drawn or elongated, with the help of godet wheels. Depending upon the desired properties, the polyester fibers are usually drawn up to five times its original length. For higher tenacity, the filaments are drawn to a greater extent. When the fibers come in contact with the air, they solidify. Usually, the PET fibers are drawn hot as it produces more uniform fibers. PCDT fibers are drawn at higher temperature due to their higher melting point. During the drawing process itself, fibers may be textured which saves time, efforts and production cost and also gives greater quality control over the finished fibers. After the polyester yarn is drawn, it is wound on large bobbins or flat-wound packages, ready to be woven into material. Types of Polyester Yarns The polyester yarns have a wide range of diameters and staple lengths. The yarns are made basically as monofilament yarns, multifilament yarns and spun yarns. Filament Yarns PET Polyester is used to make filament yarns either in monofilament or multifilament forms. The direction and amount of twists are decided by the desired end use. The properties are also pre-determined. There are various types of such yarns. There is the bright, regular tenacity polyester yarn having light, stretch and sag resistance, used for sheer lightweight fabrics like tulle, voile and organdy. The regular tenacity semi dull yarn used for various apparels including lingerie. Its more dull version is used for shirts and blouses. Polyester yarns resistant to various chemicals, and microorganisms are produced from high tenacity fibers for such industrial uses as conveyor belts, ropes and nets etc. Textured Yarns These yarns are made of PET multifilament’s. Texturizing is either done along with the drawing process or afterwards during throwing or texturizing process. Spun Yarns They are made of staple or cut PET or PCDT polyester fibers. The staple may be bright, semi dull or dull and tenacity may be regular, mid or high. It may be polished to reduce crimp and increase luster. It may either be spun alone or blended with other staple such as cotton, wool or rayon and then spun into yarn. Application of Polyester Polyester is used in manufacturing of many products, such as clothing, home furnishings, industrial fabrics, computer, recording tapes, and electrical insulation. It has several advantages over traditional fabrics as it does not absorb moisture. Its low absorbency also makes it naturally resistant to stains. Polyester clothing can be preshrunk in the finishing process. This makes it resist shrinking and it doesn't stretch out of shape. The fabric can be dyed easily, and is mildew resistant too. Textured polyester fibers are an effective, nonallergenic insulator, thus it is used for filling pillows, quilting, outerwear, and sleeping bags.

If Only I Could Go Back

It was around 9:00 pm and the atmosphere was charged. The roads were blocked and the police were to be found on every corner. A search was in place, I was the suspect. My clothes were stained with blood, not my blood but Eve's blood. My face was covered with dirt as though I had taken a dip in a pigsty. Suddenly just behind me I heard a booming sound â€Å"Freeze, don't move†, but I was too faint to synchronize with a response. Red and blue lines were flashing before my guilty eyes, it was the police. They had found me; I was handcuffed on the spot and thrown into the back of a van like a captured animal thrown into his cage. I was read out my rights â€Å"You have the right to remain silent, anything you say or do can be used against you in a court of law†. That was it, I had been on the run for 4 consecutive days. My stomach lunched with hunger, my body desperately urged for rest but worst of all I was ruined. I was filled with intense regret. Although a sense of denial ran through my head, my conscience overcame the effect and I knew what I had done was wrong. â€Å"Too late now† I thought to myself. As I neared the place of my judgment with the last bit of strength in me I shouted aloud â€Å"God Forgive Me†. Time seemed to crawl as freedom raced its way out of my life. I was utterly left to rot. Fear and regret was all I could think of. My sense of fear was so strong, that I began to cry. My emotions overpowered me once again and the more I thought of the crime I had committed the more I continued to cry. I then arrived at the police station where I saw my father standing with only one expression on his face, ‘SHOCK'. As a police officer informed my father of my actions I saw a tear form in his eyes, a tear filled with shame and disappointment. The sight of my father's face scared me all the more. A vision of an empty, lonely future came alive at the back of my head, the past 18 years of my life flashed past me so fast like a video cassette put on super forward. I then heard a rough thick voice say â€Å"Why my son, why did you beat Eve to death?† It was my father who by now had understood precisely what had happened. He was a man who went through a lot of rough times himself. I was silent. The cause of my actions was due to my family problems. The agony, the loneliness of my parents being divorced and not having a father and a mother at the same time made me feel empty. My family was very dear to me, as a ‘real family' was all I wanted. Ever since I was a child I've been brought up by a single parent and always wished to have my parents back together. I longed all my life to know how a real family life was, but I was deprived of that. I did not want my father to pity me hence; I kept the reason to myself. I am a man now and should be responsible for my actions. It was because of Eve who simultaneously insulted my family and made fun of the fact that my parents were divorced. â€Å"Your parents don't love you that was why they left you† was one of the many hurtful things she said. At first I tried to ignore it but the truth penetrated its way into me and anger was all that was left in me. The blood in my veins boiled making me all the angrier where at one point I burst and took all my anger out on her. Punch after punch, kick after kick. This is when my emotions took over me at first. Everything happened so fast, and by the time it was all over and saw Eve's helpless body lying horizontally opposite to me, I was shocked but most of all scared. This was the first time I had actually seen someone die before my own eyes, and to worsen things it was me who had â€Å"murdered† her. I acted like a robot controlled by the truth and my emotions. Then the fear of death took over me and for the first few minutes I froze at a standstill but the thought of what I had done scared me so much that I began to run as fast as I could to hide myself from what I had done. Now my life is ruined. I feel like a total failure. Till this very day each moment I sit in my jail cell, I feel helpless and hungry and regret what I had done and just wish if I can take back what had happened. The thought, the whole thing just keeps running through my mind making me feel so wrong and so bad. â€Å"Oh! If I could only go back in time!†

Bacteriophage Lambda Lysogenic Cycle Biology Essay

Bacteriophage Lambda Lysogenic Cycle Biology Essay Viruses are tiny agents that cause infections in a wide range of hosts including animals, plants, bacteria and other viruses. In particular, viruses that infect bacteria are called bacteriophages, bacterio meaning â€Å"bacteria† in Greek and phage meaning â€Å"to eat†. Bacteriophages are able to undergo lytic and lysogenic cycle to replicate; however, most undergo one or the other cycle to replicate. An example of a bacteriophage that is able to undergo both cycles is bacteriophage lambda (phage lambda). Bacteriophage lambda infects only the bacterium Escherichia coli strain k-12. Phage lambda is unique in its ability to turn replication genes on or off depending on the host’s condition. When E. coli is infected with phage lambda and the cell dies due to an environmental factor, the phage will switch from the lysogenic to the lytic replication cycle. Bacteriophage lambda was discovered by Esther Lederberg in 1950 while she was working in a laboratory with E. c oli strain k-12. Lederberg is considered a pioneer of bacterial genetics; she was also an immunologist and microbiologist. She flourished academically, receiving a doctorate from the University of Wisconsin where she worked with many other pioneers of microbiology, genetics and immunology, including: Andre Lwoff, Edward Lawrie Tatum, George Wells Beadle, Frances Crick and James Watson. While at the University of Wisconsin, Lederberg was using ultraviolet light on E. coli strain k-12 to mutagenize that specific strain of the bacteria. After prolonged exposure to the ultraviolet light, the bacteria stopped growing and its condition slowly began to deteriorate. An hour and a half after the exposure to the ultraviolet light ceased, the bacteria began to lyse (burst). This led Lederberg to the discovery of bacteriophage lambda. The E. coli sample that Lederberg was using was infected with bacteriophage lambda. The phage was not detected because it was in the lysogenic cycle, which meant that the phage was a prophage, and thus that the phage genome was integrated within the bacterial genome. Bacteriophage lambda sensed that the bacteria was about to die, so it switched its replication genes on and converted to lytic replication, therefore causing the cell to lyse and release the phage into the environment. Lederberg is also accredited with the discovery of induction; the process of when the lysogenic cycle is terminated and the lytic cycle is activated due to adverse conditions caused by ultraviolet light. Lederberg, along with her team of researchers, was awarded the Pasteur award in 1956. Viruses have many different anatomical structures depending on what kind of cells they infect. The anatomical feature that is similar throughout all bacteriophage is the capsid. The capsid or head is a shell made out of protein that contains DNA or RNA, depending on the virus. The capsid also contains some internal proteins. The capsid can have many different configurations, from a polygon-shaped sphere, like an icosahedral, or a rod-shaped helix. The main functions of the capsid are that it allows the virion to attach to its host via special sites on the surface, contains the internal proteins that allows the virus to penetrate the host cell membrane, which enables it to inject the infectious DNA or RNA into the host cell’s cytoplasm, and that it provides protection for the nucleic acid from the environment and digestion by enzymes. The capsid has structural subunits called capsomers that may contain one or many polypeptide chains. Some viruses have a secondary structure that protects the capsid itself, this is called an envelope. Not all viruses have an envelope; the envelope is made up of glyco-proteins and surrounds the entire capsid for optimum protection. The envelope has two lipid layers intermingled with protein molecules, a lipoprotein bi-layer, and also has a mixture of material that consist of the viral origin and some material from the me mbrane of the host cell. Besides a capsid, some viruses also contain a tail that is attached to the capsid which helps the virus penetrate the host cell’s outer membrane and allows the virus to inject the DNA or RNA into the host cell. The tail consists of two main structures: the tail fibers and a tail sheath. The tail fibers are tiny leg like formations that help the phage attach on to the bacterial cell by clinging on to the surface receptors. The tail sheath is a tube like structure that runs from the capsid to the tail fibers; the tail sheath digs into the cell membrane of the host and the DNA or RNA travels down the sheath and into the cytoplasm of the host and the infectious cycle begins. For viruses without tails, specialized spikes are protruding directly from the capsid that play a similar role to that of tails; the spikes are made up of proteins and help the virus invade the host cell. Bacteriophage lambda has a capsid with an icosahedral configuration that is 55 n anometers in diameter that contains 350-575 capsomers or subunits of 37,000 Daltons; the capsomers are positioned in groups of 5 and 6 subunits or pentamers and hexamers. The tail is 180 micrometers long and contains a single tail fiber that is 25 nanometers long. Bacteriophage lambda does not possess an enveloped capsid.

Phonics Practice Essay Example | Topics and Well Written Essays - 1500 words

Phonics Practice - Essay Example They are learning to solve and decode the mystery of stringed words. Learning phonics is the key to learning to read print. "Research directly points to the direct relationship between phonic instruction and success in acquiring the skill to read print. In short, evidence on the importance of phonics is incontrovertible." (Savage, ). The practice of phonics everyday is the key to mastery in reading fluently. This should be practiced with music, where songs based on phonics can be reinforced. A video approach is even more effective, as it stimulates the auditory as well as the visual concept. And it is easy for the child to remember and decode information both using their auditory and visual stimulus. Flashcards can also be used for further practice. "The English writing system is based on alphabetic principle: that is the individual speech sounds (called phonemes) are represented in writing by individual alphabet sounds (called graphemes). Children need to understand the alphabetic principle as they learn to read. Mastering these sound symbol relationships is what phonics is all about." (Savage, ). Phonemic awareness - the ability to recognize and manipulate sounds in spoken words is crucial to success in beginning reading. It is in-fact a better predictor of learning to read than listening ability, IQ and several other factors. Lack of phonemic awareness puts children at risk of failure to learning to read. Phonics should begin with rhyme recognition and rhyme production and continue with segmentation, isolation, deletion, substitution and blending of phonemes throughout the learning program. Emphasis should be on the five essential elements phonological awareness, phonics, fluency, comprehension and vocabulary. . (Savage ). Motivation should also be the key factor in reinforcing the concepts. Children should be exposed to a variety of folk tales, fairy tales, rhymes and stories from diverse cultures which can encourage them at their level of learning to code and decode the symbols and decipher the hidden meaning. This journey of exploration of literature should be rewarded by more challenging books, materials and rewards. (Savage ). Although phonics remains an essential factor in the word recognition, other strategies should also be taught in helping children identify words and unlock the meaning of words they encounter in print. Children use multiple clues in identifying words, including sight recognition, and context clues all these need to be integrated with the study of phonics to nurture a fluent reader. This lesson should begin from home before Kindergarten years and should be fully mastered by third grade. The appropriate level of challenge should be maintained throughout. These skills should be taught to help children become productive and fluent readers. "Through critical attention to relevant research and careful observation of children in the reading-writing process, we teachers can intelligently decide how to teach phonics. . . . I prefer to teach phonics strategically, in the meaningful context of the predictable stories children read and write every day. In the context of written language, phonics instruction facilitates meaning making and independence."-Regie Routman, 1991(Weaver, 1996) Comparative and naturalistic research indicates that encouraging children in phonics not through drill but integrated natural approach is more effective.

Fetal Alcohol Syndrome Research Paper Example | Topics and Well Written Essays - 1750 words

Fetal Alcohol Syndrome - Research Paper Example Alcohol consumption is the main factor in a fetus developing fetal alcohol syndrome. When a pregnant woman drinks alcohol, the alcohol enters the bloodstream and reaches the fetus by crossing the placenta; anything that enters the woman’s body is passed along to the fetus, and alcohol is no different. However, fetuses are unable to metabolize alcohol as quickly as adults, thus making the fetus’s blood alcohol concentration higher than that of the mother and more difficult to get rid of (Ulleland, 1972). Adults are able to rid themselves of alcohol within an hour for each beverage, yet fetuses do not have the ability to do so, so the alcohol sticks with them longer, often cause irreversible damage. Alcohol interferes with the oxygen being delivered to the unborn baby. It is common that babies face mental, behavioral and physical diseases and deformities when they are being denied the oxygen that they need to develop fully and healthily. This lack of oxygen greatly affects the nutrition of the baby’s developing tissues, organs, and brain, often causing babies with fetal alcohol syndrome to be born premature or with a variety of diseases or deformities. Due to science and technology, a fetus still in the womb can be pre-diagnosed with fetal alcohol syndrome based on certain signs and symptoms; unfortunately, properly diagnosing the baby can only take place after the child has been born. The first major sign is a mother that drinks regularly while pregnant. Through ultrasounds and by listening to the heartbeat of the fetus, a doctor can determine if the fetus is already facing difficulties and complications due to the intake of alcohol. Unfortunately, many of the signs and symptoms are made known after the baby has been born.   Babies often face growth deficiency, being excessively under average height and weight compared to babies born without the syndrome.  

Abstract and critique of Training Teachers to Use Naturalistic Essay

Abstract and critique of Training Teachers to Use Naturalistic Communication Strategies in Classrooms for Students with Autism and Other Severe Handicaps - Essay Example The goals and objectives are used as an assessment tool. It is called the â€Å"Individualized Education Plan†, which is a plan for each individual student. These steps are later observed in the classroom for implementation. The teachers are observed by the SLP and at any given point the teachers will be given immediate feedback by the SLP ´s corrective measures during the observation process. The teachers have to follow the suggestions given by the SLP and does not continue to the next step until the teacher has accomplished the task. The SLP gives the teacher feedback, after a 10-minute observation is done by using the â€Å"Communication Maintenance Goals checklist†. The SLP gives the observations to the teacher and the teacher gives the supervising teacher the feedback after reviewing them. The teacher should reach an 80% of competency after three consecutive observations. This study was tested in two special education classrooms at The May Institute, Inc. The children that were observed had severe communication deficits, social withdrawals, aggression, and self-injuries behaviors. The children received one-to-one and small group instruction on pre academic and academic skills, vocational skills, self-help routines, and recreation programs. There were eight children involved in this study made up by two groups of four. The children were diagnosed as having autism, severe mental retardation, or pervasive developmental delay. Their ages ranged from 7 years to 13 years. Two of the children took medications (insulin and clonodine). For the reliability, the observers had an agreement of 86% to 96% in the frequency of elicited communication maintenance goals which was 90% and for the frequency of spontaneous communication maintenance goals which ranged from 72% to 95% reaching an agreement of 81%. The authors selected one of the children, Tim, for an in-depth analysis. They presented the

Questions to answer - Essay Example This method fosters the chief motivation for reimbursing as setting up a more promising rate of interest over the period of the new issue. 3. Recognizing the difference on reimbursing is the same as the difference on other prompt terminations (Carmichael and Graham, 2010). Auditors argue that organizations should recognize this difference in income in the term of the termination. The third method makes practical sense since it is the only argument where an accountant records the whole difference when the particular agreement is extinguished. This process affects previous terms when the agreement was valid. However, the third method is the generally accepted one (FASB, 1972). This is because many accountants contend that the recognition of this difference might compel an organization to record returns by borrowing funds at high rates of interest to settle discounted, low-rate debts. I favor the first option because it takes into account equity categorization for a part of or the entire outstanding convertible debt issue. As a result, the first option is suitable for fiscal auditing and reporting from a tax point of view (Grant Thorton, 2013). Instruments with the features of both equity and liability categorizations are compound. The first option also qualifies as a requirement for the categorization of fiscal tools (Schneider et al., n.d.). FASB. (1972). APB 26: Early Extinguishment of Debt. FASB.

MTV Case Study Example | Topics and Well Written Essays - 250 words

MTV - Case Study Example Some Arab countries are not so strict while others do not entertain a breach of their rules. MTV’s entertainment in the Arab country will have to be in Modern Standard Arabic (MSA) as that is what is widely used to communicate. The reporters and presenters have to dress according to the Arabic culture; whatever is being aired on MTV should be moral and according to the social responsibility of those countries. These are too many rules and which will mean that MTV Arabia will only target the Arabic world and no other parts of the world. Critically analyze MTV’s strategy in the Middle East. Comment on its entry strategy and also its strategy of providing mixed content to the market. Do you think MTV will be able to succeed in this market? The entry strategy and the mixed content strategy of MTV where they air 60% international music and 40% Arabic music and also ensuring that around 45% of the content to be aired is produced locally might work and enable the MTV to venture the culture-bound Arabic world. Their success in that market will also be guaranteed by the fact that MTV Arabia planned to design their shows in such a way that it involves and caters for the pan-Arab youth audiences. This way it will ensure that majority of the youth agree with the program and the political aspect which is important in Arab media is also present due to the Pan-Arabic individuals being targeted. With all these strategies by MTV, there is no way that it can fail to succeed in Arabic world (Deresky,

It ensures that when disaster strikes the community recovery and restoration be fast tracked in terms of essential services (OLeary 2004). Community resilience involves identifying and evacuation route in Skagit County. This is done in collaboration with the residents and the authority that best know the area. The process of community

The reign of James I Essay Example for Free

The reign of James I Essay (a) Explain briefly the financial policies of James I (b) To what extent was finance the main problem in the reign of James I Finance was at the centre of James disputes with Parliament. After his move from king of Scotland, James overestimated Englands wealth. He spent a great deal of money on Elizabeths funeral and when the ambassador of Spain came to England, he was sure to highlight the countries riches. Parliament did not give James more money. Consequently, he was forced to resort to impositions. Salisbury came up with a great plan called the Great Contract. This meant that James would give up his feudal rights in return for à ¯Ã‚ ¿Ã‚ ½200,000 a year. However, parliament failed to disagree with this idea, if James had enough money to rule without Parliament, he would. This refusal may have led to major dispute. Luckily, James strayed from the idea himself as he feared that high inflation would leave à ¯Ã‚ ¿Ã‚ ½200,000 a small fee for his feudal rights. As was stated earlier, One of James most influential problems with Parliament was finance. However, this was not the only problem that he encountered with Parliament. Some of the most influential disagreements between the King and Parliament were the Divine Right of Kings and the right of Parliament to represent public opinion. James was very competitive and liked to win arguments, he often used his title to win battles with Parliament and matters often resulted in being matters of principle. However, Gentry became wealthier and more powerful and they became determined that Parliament would be protected and then maybe expanded. Real problems begin with foreign policy when the Thirty Year War broke out. This was a Europe wide war between Catholics and Protestants. James son in law was in the centre of the conflicts. He was a protestant King who lost his country due to self greed. Parliament wanted James to support his son and daughter in law and his country by supporting the protestant cause. This left James in a predicament. He wanted to receive the money he would need to fight the war against Spain and the holy Roman Emperor, whilst hoping to avoid war by marrying his son, Charles, with the Spanish Infanta. Thus resulting on added pressure on the Roman Empire to give the elector of Palatinate his land back. James handled the difficult issue of religion fairly well and it was not the cause of major disputes between himself and Parliament. The problem came when James inherited the Anglican Church. It contained Puritans that wanted the church to loose all traces of Catholicism and it also contained Armenians who favoured many of the Catholic ideas. James met with the Puritans at Hampton Court in 1604. James did not give way to their ideas and the meeting resulted in the issue of a new Bible. The puritans wanted to get rid of the Kings bishops so that the Church would not be under the Kings control. James refused and made them do things the way the church was already. At first James was lenient towards Catholics, maybe due to his mothers Catholic ways, suspending fines that punished Catholics for not attending the Anglican Church. However, Parliament interfered and the decision was reversed. This tougher line with the Catholics led to the Gunpowder plot, with included a plot on James life. This also resulted in armed revolution from overseas Catholics. This proves that finance was a major ingredient in the ever present boiling pot of disputes between James I and Parliament but it was not the only ingredient. James handled many issues with Parliament fairly well; however, finance was a particularly difficult matter in which to find a balance, with James wanting more money and Parliament not prepared to give it to him. Subsequently, along with help and ideas from close staff, he managed to bear with the mess of finance but without the reality that England did not the riches that James believed, he would never excel in the issue.

Culture of the Penan Tribe

Culture of the Penan Tribe The review that I would like to made among the 5 tribes that acted by the Bruce Parry is the Penan tribe. First of all, I would like to introduce briefly about the character of Bruce Parry. Bruce Parry is an activist that venture into the most remote area of Sarawak state in Malaysian Borneo. He believes that the only ways to knows more about the culture anthropology and knowledge for a tribe is to have a participant observation in his fieldwork. Participant observations mean that living within a given culture for an extended period of time, and take part in its cultural daily life in all its richness and diversity. The Penan is a nomadic aborigine that roved on the land of Sarawak Borneo and some other parts on Brunei Bandar Seri Begawan. Nowadays, the number of Penan had officially stated approximate to 10,000 people and around 350-500 of them are nomadic that scattered over Ulu Baram, Limbang, Tutoh and Lawas of Sarawak. (Figures retrieved from: http://www.survival-international.org) The present Penans are consisted with settled, semi-nomadic and total nomadic communities that fully depend on the forest products. In Penan society, the natives are highly developed in an egalitarian society and little gender division. It means that the social stratification among the man and women are almost equal. For instance, the man and women shared most of the chores among them. Such as, gathering the forest product and extracted sago from the sago palms, but they are still some part of chores that dominated by male, for example, hunting in the forest. Penan is a group of native that practiced the ritual of Molong which means that never take more than necessary. The majority of the Penan natives are work as nomadic hunter-gatherers. The nomadic Penan usually moves in group that consisted approximately 40 people included children and old people. They do not stayed for a long time in a particular place. The period of time that they stay is depend on the resources at the place that they stayed and when the resources became fewer, they will choose other suitable places and moved again. The nomadic Penan native that lived in the forest was very much depending on their traditional diet-Sago that starch from the Sago palm. Once, the Sago palms are matured and fully grown, the sago palm trees will be cut down. The leader of the collecting sago palm will make sure an amount of sago starched is enough for each family and kept adequately for their supply. After that no more sago palm will be chop down until they are ran out of food. Besides that, the Penan native also preys on wild animals like wild boars, mouse deer and monkeys. The hunters hunt by using a blowpipe, made with the Belian wood and carved out with a bone drill. The poison darts that they used are made from the sago palms tree bark and on its tip; the Penan dipped it with kind of powerful poisonous latex that extracted from a tree from the forest. However, the Penan natives also cultivate the planting of paddy and domestic animal breeding for their own foods not for sales. Furthermore, I would like to discuss briefly about the Penan culture. Culture can be defined as a learned behavior in any particular society includes those ideas, techniques and habits which are passed on by one generation to another in a sense, a social heritage and which are virtually a set of solutions to problems that, in the course of time, others have met and solved before. (Tony Bilton, Kevin Bonnett, Philp Jones, Michelle Stanworth, Ken Sheard, and Andrew Webster, 1987, page 11) The nomadic Penan move in groups and they have their own clan territories, the groups are consisted of a family of five or six members and some family even consisted of 30 people. The nomadic Penan will leave their old selap (huts) and move to another domain of forest when their sago supplies are exhausted. The majority of the roofs are tarpaulins and there are seldom roof made by giant palm leaves. In the aspect of material cultures, only Penan elders dress in traditional dress, which called chawats means that the loin cloths, and wearing large holes in their earlobes. Nowadays, the Penan natives are making the tattoos by themselves which is almost like prison tattoos. Only few Penan now go in barefoot, most of them are wearing cheap plastic boots with rounded studs to protect their foots. In addition, I would like to discuss about the Penan traditional weapons that are used for hunting. For example the Penans blowpipes which is used for hunting wild animals. The another name for blowpipe is called keleput, are approximately 6 feet long and made from one solid piece of iron wood. Secondly, the process of making the Penan poison darts is cutting off the bark of the tajem tree to extract milky latex that is warmed over a fire to produce the poison. The poison darts can cause lethal arrhythmias to the animals. Blowpipe darts are made from palm fronds with light weight. Darts with metal tips which cut from tin cans are used for bigger size wild animals like deer and bearded pig. The last weapon used by Penan hunters is knives. The Penan hunters are carrying two knives. The first knife is called a poeh, is large and machete-like. The second knife is called darhad which is much smaller than peoh and is used for cutting meat, whittling blowpipe darts and fine work. Both knive s are carried close together with the Penan hunters. Besides that, in the aspect of religion believe for Penan native, the Penan have been converting their animism belief to Christianity since in the 1930s. According to the functionalist Emile Durkheim, religion is a unified system of beliefs and practices relative to sacred things, that is to say, things set apart and forbidden beliefs and practice which unite into one single moral community called a Church, all those who adhere to them. (Robert Van Krieken, Daphne Habibis, Philip Smith, Brett Hutchins, Michael Haralambos, Martin Holborn, 2006, page 390) However, some of the Penan native still having a strong believe in myths and spirits. The Penan leaders still practice the ritual of blood pacts with neighboring tribe when doing the political agreement. The ritual of blood pacts was believed that anyone who breach of this pact will cause to vomiting of blood and a violent death. Moreover, in the aspect of economic for Penan native, most of the Penan are work as a hunter gatherer in forest and selling the main resource of the forest which is sago. The economy can be defined as a system of production, distribution, and consumption of resources, including the cultural belief that supports economic processes. During the colonial times, the British government will arrange trading missions called tamu close to the forests of the Penan to offered forest products like damar (now used in eco-paints), rattan mats and baskets, rhino horn, gaharu wood (or eagle-wood), wild rubber, monkey gallstones (for Chinese medicine), bills of hornbills, and deer antlers. These items were traded for manufacturing goods like knives, cooking pots and shotguns. None of these forest products are now abundant, but many Penans will sell surplus meat to logging camps. The Penan native also sold the high quality gaharu from gaharu tree but that can take years to accumulate. Gaharu is used a s incense, for medicinal and religious purposes, and as a perfume in the Middle East countries. For the division of labor for Penan, the man will always go for hunting and the woman will generally gather the sago from the sago palm tree and do the house chores. The pattern of economic subsistence for Penan native is foraging and horticulture. For instance, they are foraging in groups for wild plants and hunting for wild animals like wild boar and mouse deer. However, some Penan hunter still practicing the pedestrian foraging which means that the hunters are diversified hunting and gathering on foot. For the horticulture, they also rear some chickens, pigs, and monkey outside their house. The Penan native also having symbolic interactionism when they are hunting inside the forest. According to the principal ontological claim of symbolic interactionist is that reality is not immutable or fixed but is constantly being recreated or achieved through the meaningful interaction of individuals. (Tony Bilton, Kevin Bonnett, Philp Jones, Michelle Stanworth, Ken Sheard, and Andrew Webster, 1987, page 521) Symbolic interactionism means that the interaction among people, how people use symbols in communication and interaction to establish meaning, develop their view of the world, and communicate with one another. The Penan natives have their own forest sign language. For example, a bent twig stuck in the trail may simply delivering the direction of the hunter is going. The complex arrangements of cut twigs, sticks and folded leaves means that delivering the message to the Penan native about anything from the state of the hunting locally to the others hunter whether they are in go od mood or not. Furthermore, the Penan native also facing social changes in the Penan society. In general terms social change refers to the changes in the nature, social institution, social behavior or social relations of a society, or other social structures. According to Barbara Marliene S. Mary Ann A. Schwartz (2006) social change was defined as the time when external events happened, such as war and conquest and culture contact and diffusion, or environmental factors or internal events, such as innovations, invention and population shifts. For instance, in Penan society, the Penan native was influenced by the cultural diffusion from western, such as wearing t-shirt and jeans, cooking pot and cups made from western and lastly some of the hunter are using shotgun for hunting instead of using the blowpipes. The collective action also occur among the Penan natives toward the government when the logging company keep on cutting of the tree in Penan forest without paying any compensate and development to the Penan area. For example, many blockades were set up in attempt to stop logging operations on their land. Unfortunately, the efforts were hard to carry on and the situation turns bad with vast scale of clashes between the indigenous community and the state supported logging company. The Penan native also facing social changes because of the the geography and climate. It is because, the Penan natives is dealing with the survival problems inside the forest. Their food becomes hard to attain and the inhabited environment was contaminated because of the serious logging happened in Penan forest. These kinds of situation makes their natives life in the jungle becomes tough and unease. So, the member in the group is keep decreasing due to migration. Migration refers to the movement of people into or out of a geographical area (Barbara S Mary A, 2006). So, in future, many youngsters who grew up in the nomadic group will choose to move out from the community and headed to the life style in the city. It is because the young people rather choose a spouse from the city than they own people that stayed in the group. In the aspect of development in Penan society, the Penan native did not want any development from the government to them and they just want their own traditional life remains. According to Hunt, E. F. Colander, human being appears to be basically conservative and the human mind and personality are so constituted that once people beliefs, attitudes, and patterns of behavior, they have difficulty in changing them. (Hunt, E. F. Colander, D.C. 2005, page 90) The statement above have shown that why the Penan natives reject the development from government. However, the logging company which could bring development and economic rises to the country have also cause a lot of negative impact to the Penan natives. For instance, the poorly planned logging trails had caused the issues of earth erosion, landslides and the silting of watercourses happened. The situation had affected the functional relation among the Penan and the forest. The big trees which were removed had cause the Penan native hard to gather and hunting for their foods. Lastly half of the habitat of Penan native was being demolished. In the aspect of family in Penan society, the Penan natives are having closure group of marriage, it means that the Penan native will only married each other which is in their own tribe. According to Murdock, family is a social group characterized by common residence, economic co-operation and reproduction. It includes adults of both sexes, at least two of whom maintain a socially approved sexual relationship, and one or more children, own or adopted, of the sexually cohabiting adults. (James Fulcher, John Scott, 2007, page 447) Most of the family in Penan society is nuclear family and extended family. Nuclear family refers to a domestic unit composed of a man and woman in a stable marital relationship, with their dependent children, and the extended families refer to where more than one generation of husbands and wives cohabit with their offspring. (Tony Bilton, Kevin Bonnett, Philp Jones, Michelle Stanworth, Ken Sheard, and Andrew Webster, 1987, page 253) Most of the family member in Penan was built in extended family where the Penan natives live and work together inside their huts. In the aspect of gender in Penan society, gender can be defined as a term that has psychological or cultural rather than biological connotations. If the proper terms for sex are male and female, the corresponding terms for gender are masculine and feminine; these latter might be quite independent of biological sex. (Robert Van Krieken, Daphne Habibis, Philip Smith, Brett Hutchins, Michael Haralambos, Martin Holborn, 2006, page 304) The Penan natives are having their gender identity through the gender socialization. According to Ann Oakley, gender socialization is how socialization in modern industrial societies shapes the identity and behavior of girl and boys from an early age. (Robert Van Krieken, Daphne Habibis, Philip Smith, Brett Hutchins, Michael Haralambos, Martin Holborn, 2006, page 316) For instance, the Penans male when they are born they have to be a hunter-gatherer and do some rough work or learning the skill of doing rattans. The female who are born will have to do the h ouse chores with their mother and do the fine work like collecting sago or fruits. As a conclusion, the social changes have caused a lot of conflict among the Penan tribe and the government. Individual, groups, communities are reluctant to change and facing big struggle to adjust from the life style and conditions that they had used with, so many aspects in life have to be considered. At the same time the society have to differ themselves to maintain existing conditions. The Penan resists change because of their romanticized notion of traditional values and the good old days. (Barbara S, Mary A, 2006) For example, the Penan people valued their forest habitat and their traditional rituals very much and fear of losing each of them caused them hesitated to receive changes. So, the phenomenon of the Penan resistance is natural and it is common if they persisted in their objection. References: James Fulcher, John Scott. 2007. Sociology: Third Edition. United States.
