Organic memory transistor Essay Example | Topics and Well Written Essays - 750 words

Organic memory transistor - Essay Example They (Fakher & Mabrooka, 2012) reported that the output characteristics for both the devices show perfect and good saturation area at low and high voltage; VDS respectively. They also found out that, in the control device, the mobility (Â µ), the threshold and the on/off rotation were 0.27cm2 V-1S-1, 16V and 4.1 X 104 respectively. However, in the organic memory floating gate; the mobility was found to be 0.04 cm2 V-1S-1, the threshold was between -23 and -47 volts while the on/off ratio was 2.3 X 103. For high mobility and increasing on/off ratio, the smooth surface, uniform and loose pin holes where the reverse proportionality of PMMA concentration which was above 15wt%, and can be a significant influence on the average grain region and average roughness of pentacene layer. They also stated that a clear trend was there to show that there was no hysteresis in the control transistor due to non charge storage element. In addition, they said that the gold floating gate of the organic memory transistor causes low mobility due to the gold nanoparticle affected to follow and carry charges from the first layer of PMMA through gold floating gate to the second layer of the PMMA in the insulator. ... That was when different pulses of OTMFTs were applied to the gate electrodes. This was evident in non-volatile state attitude for the organic thin film memory transistor device. Graphene oxide and floating gate: Other authors, including Tae-Wook Kim, Yan Gao, Orb Action, Hin-Lap, Hong Ma and others, also reported about the electrical characteristics of organic non-volatile memory transistors (ONVMTs) using chemically synthesized grapheme oxide (GO) as a charge trapping layer based on pentacene/PMMA/Grapheme oxide nanosheets/SiO2.GO (Kim, et al., 2010). the nanosheets were produced by modified Hammer’s process then deposited on top of SiO2 substrate using spin coating and hot plate (3000 rpm for 40s and 120C0 for 10 minutes), respectively. The drain/source contact was of gold and had a thickness of 50nm thick and a semiconductor layer of 50nm was deposited using thermal evaporation of pentacene. The GO nonosheets were located between PMMA and SiO2 layers of about 10nm of thickn ess. A clear trend, morphological properties of grapheme oxide such as rougher and coverage region were dependent on the concentration of its solution. The output and transfer characteristics of both the devices, namely; control (OFETs) device without grapheme nanosheets and (ONVMTs) device within GO nanosheets, have similar values of mobility ), threshold and on/off ration which were 0.16 cm2V-1S-1, 6.5V and 106 respectively. On the other hand, travelling electrons or hole from pentacene to GO nanosheets through PMMA layer resulted to hysteresis which was featured in the transfer characteristics of (ONVMT) device. However, there was no hysteresis in the control (OFET) due to the absence of the trap charge

The History of Kuwait Assignment Example | Topics and Well Written Essays - 1000 words

The History of Kuwait - Assignment Example The country is a constitutional monarchy but has a parliamentary system of governance. The constitutional emirate is a hereditary position and the emir is the chief of state while the head of government is the Prime Minister and deputy prime ministers who both are appointed by the emir. The legislature consists of 66 seats with 50 states elected by popular vote while appointed cabinet ministers occupy the rest. The judiciary is based on Sharia law and is impendent from government influence (Casey 19). Most of the Kuwaitis are Arabs and Islam is the dominant religion in the country with the majority being Sunni Muslims. Foreign groups include Iranians, South Asians, and expatriates and the official language is Arabic, but English is also spoken (O’Shea and Spilling 45). The religious minorities include Parsi, Hindu, and Christians and Native Kuwaitis do not pay any taxes. Kuwait’s foreign-policy making is based on quiet diplomacy, clarity, and straightforwardness and aim s at strengthening cooperation with other countries on the basis of non-intervention in the internal country affairs and mutual trust. Kuwait’s foreign policy is based on the ideals of sovereignty and freedom of political decision (O’Shea and Spilling 17). The Emir, Crown Prince, Prime Minister and government ministers occupy the executive branch and are key decision-makers. The chief of State is Emir Sabah al-Ahmad al-Jabir al-Sabah (since 2006) and Crown Prince is Nawafal – Ahmad. The decrees and pardons are executed by the Emir and have a lot of influence on the foreign policy decisions. The Emir is hereditary and is tasked with appointing the Prime Minister, and deputy prime ministers and approves the council of government ministers that is appointed by the Prime Minister (Casey 61). The parliament is a key decision-maker in foreign policy since it has the power to initiate legislation, remove the Emir and question actions of government ministers.

Leisure in Society. Golf Essay Example | Topics and Well Written Essays - 2000 words

Leisure in Society. Golf - Essay Example According to ESRC fact sheet the most popular leisure time activity in the UK is watching TV. However, the main problem, which arises, is the lack of movement and physical activity in the lives of the British population. According to the research conducted in Bristol over 10Â  % of 11-year-old children should move more actively and are recommended to make daily exercises. The other survey conducted by the Avon Longitudinal Study of Parents and Children came to the conclusion that children from more well-to-do families make less exercise than children from poorer social background and girls were less active than boys / BBC News, 2005/. Medical surveys, which took place in 2002, showed the same results that over 22Â  % of male and 23Â  % of British female population were obese. Besides, some part of the population was not obese but overweight. These are 43Â  % of males and 34Â  % of female population of the UK. Thus, according to the Body Mass Index over 50Â  % of all adult population of Great Britain is overweight and were recommended to control their weight / Office for National Statistics, 2005/. On the other hand, it should be mentioned that there is a growing interest to the sport activities in the UK. Thus, the General Household Survey made a research of the most popular sporting activities of grown-ups (aged 16 and more). The results of the survey are represented on the table below/ Office for National Statistics, 2005/ : The only corrections, which I would like to make in this list is to include angling. Thus, according to the Environment Agency approximately 11Â  % of all British population has fished during the past two years / Environment Agency, 2007/. Therefore, I would like to mention this kind of sport activity as one of the popular activities of the UK population both of men and women. On the other hand, the other hand, which we also should take into consideration, is the organization of the sport activity. Thus, according to

Comparative and interactional Aspect of Hinduism and Buddhism Religion Essay

Comparative and interactional Aspect of Hinduism and Buddhism Religion - Essay Example One thing common about the two, they emanated from India thus sharing common ideologies and roots (Elliot 16). Buddhism, in its origin at least is an offshoot of Hinduism. Though ranked amongst the profound religions in the world, Hinduism comes third and is much more popular than Buddhism. The founder of Buddhism known as Guatam Buddha had in early life brought up in posh life of Hindu society. This gives reference for Hinduism that it interconnects with Buddhism. Hinduism, better known as ‘Sanatan Dharma’, according to the Hindu people, it forms the indigenous life of the society, though its origin is still not certain. Factual studies have concluded that Buddhism grew because of the intricate nature involving Hinduism. Despite these differences, the two share a lot in common. This paper will draw the comparative analysis of the two religions, as well as how they differ from each other. On ritual dimensions, Buddhism and Hinduism belief and in practice of meditation. B uddhism does follow some rituals like meditation, bowing to the ground in worship while offering their prayers in their Buddhist holy places. Buddhist practices and rituals do not require any priest. On the side of Hindus, their rituals are complex as they vary from birth to death of that particular person. Unlike in Buddhism, priest on the part of the Hindus plays a major role in practice of these rituals (Elliot 140). This aspect form part of their ethical teachings. Despite this difference in them, meditation as a ritual has influenced their life. The two religions believe that meditation brings them close to nirvana. In Hinduism, someone has to intone in repetition the words ‘OM’ for focus and extol himself to higher realm. Through meditation, the worshipper drives to deep link to the holy deity. This comes due to the continual practice of this focusing technique; it brings them closer to eventual certainty and close to the proximity of more knowing. Equally, Buddha went through this thorough deep meditation. In their belief, through Buddha’s meditation He realized the power within, the deity of Dharma. This makes the ritual important to the followers of Buddhism. In order to reach nirvana, Buddha learned that inward reflection was the only way thus encouraged others to do so by practicing meditation (Elliot 270). Therefore, the two faiths delve on meditation. s Buddhism and Hinduism have universal understanding on the concepts of soul recreation. They differ on the value of sacred texts. As for the Hindus, Vedas is their pinnacle Smriti writings. It is part of the old age drafts, the times of Aryans. There are four divisions on Vedas . They contain over a thousand hymns, prescriptions on customs and fairy-tale stories on their gods. The writings travel around cyclical ideas as in other religions such as sustaining tranquility and normalcy in the world we live in. On contrary, Buddhism does not believe in such doctrines, or any other Hi ndu scriptures. They have they own scriptures known as the Tripitaka. This highlighted Buddha’s tradition. Rules of basic living and moral modalities as well as Buddha’s teachings and sermons abound there. They teach philosophical collections as well (Elliot 214). These comparisons highlight the nature of these two world religions and their etymological ratings. On the issue of Samsara, Hinduism and Buddhism converge to it. To both, living never ends for there exist circle of birth, death, and re-birth. For the Hindu’s, life is recurring, having neither the beginning nor demise. On point of death, away from the world we are reborn in another life but in very unimaginable form. These forms can vary. This successive rebirth allows one to continue learning, and live in respect of the personal dharma. Hinduists believe living in

Fruit and Vegetables in Australian Market Essay

Fruit and Vegetables in Australian Market - Essay Example Agriculture does not play a dominant role in the economy of the country and its share of Gross Domestic Product is only three percent. "Gross farm product (GFP), which is a measure of the value added in production contributed by businesses classified to the Australian and New Zealand Standard Industrial Classification (ANZSIC) Subdivision 01 (Agriculture). In 1999-2000 GFP was calculated to be $17.6 billion, or just under 3% of gross domestic product." (7113.0- Agriculture, Australia, 1999-2000 2006). Still the country produces a wide variety of crops including fruits and vegetables. Even though Australia is self sufficient in agriculture, the country also imports fruits vegetables and other agricultural commodities mainly due to rising process of domestic produce and increased demand. "The report says that the rising population and demand, low productivity growth and increasing Australian horticultural prices relative to world prices, will place considerable pressure on imports." (A ustralia: Imports Threaten Fruits and Veges 2008). It would be pertinent to find out how the producers from different parts of this vast country are able to market their produce to the local population. The backbone of the fruit and vegetable market in the country is handled by what is known as the Australian Central Markets. There are six central markets in the country and it is responsible for handling a majority of the fresh produce in the country. "The majority of Australia's fresh produce is either traded or transhipped through Australia's central markets." (About the Market). The concept was a recent one that started operations in 2001 with the purpose of streamlining the wholesale market of fruits, vegetables and flowers in the country. According the above mentioned website, the Central Market Association of Australia is the coordinating agency of the six central markets who are members of this nodal agency. The six member association spread representing nearly all of the fru it and vegetable market in the country are The Adelaide Produce Markets Limited, Brisbane Markets Limited, Melbourne Market Authority, Newcastle Market Pty Ltd., Perth Market Authority and Sydney Markets Ltd. The market is not open for business by individuals for domestic use. This study will focus only on the Melbourne Market Authority since it is representative of the whole country. This market comprises of nearly 600 producer and wholesaler outlets and 140 wholesale trading units. The website says that "Over 1800 individual fruit and vegetable buyers representing independent greengrocers, supermarkets, restaurants and food processors source their produce direct from the Market. Many more receive deliveries and consignments from the Markets." Hence this figure also represents the retail market of the country. A wide variety of fruits and vegetables are available for purchase and resale. About 86 varieties of fruits and nearly eighty five varieties of vegetables are available here which is ultimately made available to the individual consumers. It includes apples to bananas, beetroot, breadfruit, Changko Manis, Chive (Onion Chives), Currant (Red Currant), Fig, Gooseberry, Hogg Plum, lemon, Loganberry, Mango, Olive, Pea Shelling, Potato, Strawberry, Turnip, Winged Bean etc. (Market Fresh News 2008). This list is just to show the wide variety of common and exotic fruits and vegeta

The movie Dead Poets Society Essay Example | Topics and Well Written Essays - 1250 words

The movie Dead Poets Society - Essay Example With his wit and wisdom, Keating inspires his students to pursue individual passions and make their lives matter. (Weir, whole film).This movie highlights four important aspect of social psychology, namely group influence, non-conformity, effects of culture on self-esteem and heroism from disobedience. With the careful and efficient incorporation of the said social psychology aspects, this movie has become one of the most highly rated educational movies. The theory behind group influence as a social construct is that a person's development- mood, behavior and outlook in life- is shaped by the norms and thinking of the groups in which he associates himself. A child who is immersed in a religious family generally tends to be a moralist while one who grew up with criminals tends to be one himself (Hewstone, 143) We can see this factor vividly at work in the film in two different conditions. The first is that of the influence of the school to the young minds of the children and the second is that of the influence of John Keating to the tendencies of his student. The school has always been regarded as a major setting for the personality development of a person. Not only do we learn the machinations of the world we live in, we are also instructed on the prim and proper ways of how to act, think and communicate. With regards to the first scenario, we see Welton Academy structuring its students as academic achievers and outstanding lawyers and doctors. To achieve this, they apply a curriculum devoid of any romantic (i.e. artistic) topics such as poetry and the arts. The school can therefore be seen as the group and its teachers as the influencing members. The students, immersed in such culture of high expectations and strict teaching, develop a preference for realistic ideas and shield one's self from romantic ones. It is apparent that the school leads them to the side of realism (i.e. fact based) rather than romanticism. This preferential system is exhibited by Richard Cameron's signing of the documents incriminating John Keating's who he perceives is going against what the school taught him. On the other hand, we see John Keating influencing the students by introducing them to poetry and the ar
