For rice husk, The TG and DTG curves in Fig. 2 and 3 shows that there are three main peaks during the combustion process and each one has a clear burnout temperature. The first peak at the temperature of 100℃ is observed due to the evaporation of moisture and volatilization of small organic molecules deposited onto rice husk surfaces. The second peak with a maximum weight loss rate of 12.56%/min at temperature of 296℃results from continuous evaporation of moisture and loss of volatiles contained in rice husk. The third peak occurs between 420℃ and 590℃, with a maximum weight loss rate at 505℃. The results indicate that char gasification, loss of volatiles, and fixed carbon and combustion of hydrocarbons are included. It is possible because rice husk is made of various hydrocarbons species with a wide range in boiling point. TG and DTG curves show that the combustion process of sewage sludge is very different from rice husk. The shapes of peaks for DTG profiles of sewage sludge are not sharp. It is due to weight loss of sewage sludge shows a slow process and higher ash content during combustion. The first peak near the temperature of 100℃ is observed due to the evaporation of moisture. The second peak with a maximum weight loss rate of 2.24%/min at …show more content…
The effect of sewage sludge materials on accelerating rice husk oxidation was verified. Besides, rice husk and sewage sludge blends showed few response to DSC tests at second and third stage with low heat release compared with that of the test rice husk alone.
Based on above, it should be noted that the different physical/chemical properties among different raw biomass materials may lead to different handling and combustion behaviors, which usually result in the operational difficulties when utilizing biomass in energy conversion applications.

...CHAPTER ONE INTRODUCTION In developing countries, millions of young children suffer from nutritional deficiencies and frequent infections. There is now a large and increasing body of evidence to indicate that nutrition and health affect human’s cognitive, motor, and behavioral development, both pre- and postnatal. The impact of a biological insult depends on the stage of a child’s development, as well as the severity and duration of the insult. However, because nutritional deficiencies and infections frequently occur together, the problems resulting from any one insult may be exacerbated by the presence of another, and the effects can be cumulative. The study of nutrients in food, how the body uses nutrients, and the relationship between diet, health and disease. Major food manufacturers employ nutritionists and food scientists. Nutritionists may also work in journalism, education and research. Many nutritionists work in the field of food science and technology. There is a lot of overlap between what nutritionists and dietitians do and studied. Some nutritionists work in health care, some dietitians work in the food industry, but a higher percentage of nutritionists work in the food industry and food science and technology, and a higher percentage of dietitians work in health care. One could very loosely generalize and say that a nutritionist focuses firstly on a food, and then looks at its effects on people, while a dietician looks at the human, and then how that human's health...

MIRAVALLES DONITA S. ESTRELLA KREANNE IRISH J. MILLANO ANGELA LEONOR M. MUTUC Researchers CLUSTER 1: APPLIED SCIENCE TEAM CHAPTER I INTRODUCTION Economic crisis runs throughout different places in the world. The Global Economic Crisis pulled countries down from around the globe to a recession. Wide-ranging declines in many aspects of growth characterize the overall impact it had on the global scale. This is the main reason why people tend to lessen the spend of money. To reduce spending, households had to buy cheaper goods, for example, instead of buying branded clothes; people tend to buy more affordable clothes. People also tend to lessen the electricity and water consumption. Another way is using charcoals instead of Liquefied Petroleum Gas or LPG in preparing or cooking their food. Almost all of us are aware of Global warming. It is the unusual increase in the Earth's surface temperature since describe the beginning of the 20th century. Scientists believe that this is caused by some human activities like illegal logging, deforestation, burning of garbage, fumes of factories, and smoke from vehicles, improper deposal of garbage and regular using of insecticides. The greenhouse effect is a vital natural process that...

Received 30 March 2011; accepted 17 May 2011 a b Abstract The strength of concrete is a function of the proportions of the constituent materials, namely, cement, water, fine and coarse aggregates. The conventional methods used to determine the mix proportions that will yield the desired strength, are laborious, time consuming and expensive. In this paper, a mathematical method based on modified regression theory is formulated for the prediction of concrete strength. The model can prescribe all the mixes that will produce a desired strength of concrete. It can also predict the strength of concrete if the mix proportions are specified. The adequacy of the mathematical model is tested using statistical tools. Keywords: Concrete; Regression theory; Prediction; Mix ratios. 1.

Study in Pechay

...Introduction Banana (Musaspp.) is the fourth most important global food commodity after rice, wheat and maize in terms of gross value production. At present, it is grown in more than 120 countries throughout tropical and subtropical regions and it is the staple food for more than400 million people (Molina and Valmayor, 1999). Among the production constraints, Fusarium wilt caused by the fungus Fusarium oxysporum f.sp cubense(Foc) is the most devastating disease affecting commercial and subsistence of banana production through out the banana producing areas of the world (Ploetz, 2005). The disease is ranked as one of the top 6 important plant diseases in the world (Ploetz & Pegg, 1997). In terms of crop destruction, it ranks with the few most devastating diseases such as wheat rust and potato blight (Carefoot andsprott, 1969). The disease almost destroyed the banana export industry, built on the Gros Michel variety, in Central America during the 1950’s (Stover, 1962). In addition, the widely grown clones in the ABB ‘Bluggoe’ and AAA ‘Gros Michel and Cavendish’ sub groups are also highly susceptible to this disease worldwide. Presently, Fusarium wilt has been reported in all banana growing regions of the world (Asia, Africa, Australia and the tropical Americas) except some islands in the South Pacific, the Mediterranean, Melanesia,and Somalia (Stover, 1962; Anonymous, 1977; Ploetz and Pegg, 2000).

No. 01/12 Division of Engineering & Technology Management (D-ETM) Institute of Engineering Leadership (IEL) Faculty of Engineering 1    Disruptive Innovation in Emerging Markets: Strategies Used in India and China Ruan Y., Hang C.C., Annapoornima M.S. Abstract The appropriate type of innovation which can meet the needs of the mass population in the bottom of pyramid (BOP) has not been studied much in the literature. Based on the theory of disruptive innovation, we offer 11 cases from India and China – the two biggest emerging markets to show that disruptive innovation could be an appropriate, feasible, and powerful innovation force to the companies and the economies involved. We also examined the R&D strategies used in these cases based on the framework proposed by Yu & Hang (2011) and found that 3 out of the 4 strategies commonly used in the cases from developed markets were also applied in the cases from emerging markets. In addition, we have identified 3 unique strategies which emerged from the cases from India and China, namely frugal engineering, modularization, and drastic manufacturing cost reduction. Based on the frequency of the usage of these strategies, we drew practical implications for local companies and multinational companies. Our study also provides critical insights to policy makers...

...Lesson Nine A Dill Pickle Part One Warm up I. Dictation Katherine Mansfield (1888—1923), British short-story writer, was born in Wellington, New Zealand. She is considered one of the greatest masters of the short-story form. At the age of 18 she settled in London to study music and to establish herself as a writer. In 1918 she married English literary critic ,John Middleton Murry. Mansfield's middle class provided the setting for many of her stories and mortality—perhaps due to her illness—dominated her writing. Her background years were burdened with loneliness , illness, jealousy and alienation —all reflected from her work in the bitter depiction of marital and family relationships of her middle-class characters. As a New Zealand's most famous writer, she was closely associated with D.H. Lawrence and something of a rival of Virginia Woolf. Her short stories are also notable for their use of . Much influenced by Russian writer Anton Chekhov, Mansfield depicted events and _____ changes in human behavior. II.

...IGOROTS * Home * IGOROT SONGS * IGOROT DANCE * IGOROT TRADITIONS * MONEY ON THE MOUNTAIN IGOROT TRADITIONS IGOROT TRADITIONS When we talk about Igorot identity and culture, we also have to consider the time. My point is that: what I am going to share in this article concerning the Igorot culture might not be the same practiced by the Igorots of today. It has made variations by the passing of time, which is also normally happening to many other cultures, but the main core of respect and reverence to ancestors and to those who had just passed is still there. The Igorot culture that I like to share is about our practices and beliefs during the "time of Death". Death is part of the cycle of life. Igorots practice this part of life cycle with a great meaning and importance. Before the advent of Christianity in the Igorotlandia, the Igorots or the people of the Cordilleran region in the Philippines were animist or pagans. Our reverence or the importance of giving honor to our ancestors is a part of our daily activities. We consider our ancestors still to be with us, only that they exist in another world or dimension. Whenever we have some special feasts (e.g., occasions during death, wedding, family gathering, etc.), when we undertake something special (like going somewhere to look for a job or during thanksgiving), we perform some special offer. We call this "Menpalti/ Menkanyaw", an act of butchering and offering animals. During these times we call them...

Mojares He was the greatest Filipino writer of his generation. Over six decades and a half, he produced a body of work unmatched in richness and range by any of his contemporaries. Living a life wholly devoted to the craft of conjuring a world through words, he was the writer’s writer. In the passion with which he embraced his country’s manifold being, he was his people’s writer as well. Nick Joaquín was born in the old district of Pacò in Manila, Philippines, on September 15, 1917, the feast day of Saint Nicomedes, a protomartyr of Rome, after whom he took his baptismal name. He was born to a home deeply Catholic, educated, and prosperous. His father, Leocadio Joaquín, was a person of some prominence. Leocadio was a procurador (attorney) in the Court of First Instance of Laguna, where he met and married his first wife, at the time of the Philippine Revolution. He shortly joined the insurrection, had the rank of colonel, and was wounded in action. When the hostilities ceased and the country came under American rule, he built a successful practice in law. Around 1906, after the death of his first wife, he married Salomé Márquez, Nick’s mother. A friend of General Emilio Aguinaldo, Leocadio...
