...CASSAVA LEAVES AS AN POTENTIAL EMULSION SURFACTANT FOR DETERGENTS ____________________ A Research Project Presented to the Faculty of the Science Technology and Engineering Batasan Hills National High School IBP Road, Batasan Hills, Quezon City ____________________ In Partial Fulfilment of the Requirements for the Research III ____________________ by Borromeo, Kristine Joy R. March 2016 CHAPTER I THE PROBLEM AND ITS BACKGROUND Background of the Study Almost every human uses detergents everyday, the problem is we had gone too far in using detergents. Detergents are for cleansing that are daily in use. They are becoming more and more expensive and on demand because of their increasing purposes. In this modern age, detergents are not as effective as what like they said in ads and commercials because sometimes too much chemicals re used which can affect its effectivity. The research is done to find out an alternative solution for the problem said in detergents using cassava leaves. Cassava leaves is common inside the community. The solution aims to produce the as an potential emulsion surfactant for detergents using the cassava leaves. The product does the same job as others but is more natural because an organic specimen is added. It contains less harmful chemicals. The said product will perform important functions in detergents cleaning such as loosening emulsifying and holding suspension until it can be rinsed (Healthy Cleaning 101, 2010 ) . ...

Nature has always inspired human achievements and has led to effective materials, structures, tools, mechanisms, processes, algorithms, methods, systems, and many other benefits (Bar-Cohen Y (ed) 2005 Biomimetics—Biologically Inspired Technologies (Boca Raton, FL: CRC Press) pp 1–552). This field, which is known as biomimetics, offers enormous potential for inspiring new capabilities for exciting future technologies. There are numerous examples of biomimetic successes that involve making simple copies, such as the use of fins for swimming. Others examples involved greater mimicking complexity including the mastery of flying that became possible only after the principles of aerodynamics were better understood. Some commercial implementations of biomimetics, including robotic toys and movie subjects, are increasingly appearing and behaving like living creatures. More substantial benefits of biomimetics include the development of prosthetics...

Acda Department of Forest Products and Paper Science, College of Forestry and Natural Resources University of the Philippines Los Baños, College, Laguna 4031 Philippines This study investigated the use of waste chicken feather (barbs and rachis) as reinforcement in cement-bonded composites. A series of composite boards consisting of various proportions of waste feather, cement, sand, and chemical admixtures were prepared. Mix workability decreased significantly as the proportion by weight of feathers or ground feathers increased from 5% to 20%. Boards containing 5% to 10% fiber and/or ground feather by weight showed comparable strength and dimensional stability to commercial wood fiber-cement composites of similar thickness and density. Stiffness, flexural strength, and dimensional stability of the feather-cement boards decreased as the proportion of feathers was increased above 10%. Higher proportions of feather, however, showed significant reduction in modulus of elasticity (MOE) and modulus of rupture (MOR), and increased water absorption and thickness swelling after 24 hours of soaking in water.

...fuel production by indirect coal liquefaction Eric D. Larson Princeton Environmental Institute, Princeton University Guyot Hall, Washington Road, Princeton, NJ 08544-1003, USA E-mail: elarson@princeton.edu Ren Tingjin Department of Thermal Engineering, Tsinghua University, 100084 Beijing, China This paper reports detailed process designs and cost assessments for production of clean liquid fuels (methanol and dimethyl ether) by indirect coal liquefaction (ICL). Gasification of coal produces a synthesis gas that can be converted to liquid fuel by synthesis over appropriate catalysts. Recycling of unconverted synthesis gas back to the synthesis reactor enables a larger fraction of the coal energy to be converted to liquid fuel. Passing synthesis gas once over the synthesis catalyst, with unconverted synthesis gas used to generate electricity in a gas turbine combined cycle, leads to less liquid fuel production, but provides for a significant second revenue stream from sale of electricity. Recently-developed liquid-phase synthesis reactors are especially attractive for ‘‘oncethrough’’ processing. Both ‘‘recycle’’ and ‘‘once-through’’ plant configurations are evaluated in this paper. Because synthesis catalysts are poisoned by sulfur, essentially all sulfur must be removed upstream. Upstream removal of CO2 from the synthesis gas is also desirable to maximize synthesis productivity, and it provides an opportunity for partial decarbonization of the process, whereby the removed CO2 can...

...What is Microbiology? Microbiology is the study of organisms too small to be seen with the naked eye. Originally, emphasis was placed on harmful micro organisms which cause disease or spoilage of beverages and food, but it is now recognized that many microbes have essential roles in our ecosystem or can be used to accomplish beneficial tasks. Human history is full of examples of major devastations caused by bacteria and viruses. Some of these historically important diseases still occur, such tuberculosis and yellow fever. Microorganisms are evolving to cause new infectious disease problems such as Lyme disease and AIDS, which capture public attention. Control and eradication of infectious diseases remain important goals of many microbiologists. The recognition that microorganisms were responsible for what was earlier thought to be "spontaneous generation" opened the door to industrial (pharmaceutical, chemical, energy) and food microbiology, technologies which contribute substantially to today's way of life. Microorganisms in soil and water are essential in the transformation of carbon, nitrogen, oxygen, sulfur and iron to products needed by plants and animals. In various ways, microbes participate in environmental cycling and degradation and global change. In the last few decades, microorganisms have been recognized as ideal model systems for the study of basic biological processes. More recently, microbiologists have brought an exciting dimension to the study of biology...

...India-Japan Economic Partnership Agreement: Gains and Future Prospects Preface India signed a two-way Comprehensive Economic Partnership Agreement (‘CEPA’ or ‘the Agreement’) with Japan on 16 February 2011. CEPA would provide a framework for enhanced cooperation between the two countries and is aimed to facilitate trade in goods and services and increase investment opportunities, besides protecting intellectual property rights. The Agreement is likely to be implemented from 1 April 2011. The highlights of CEPA have been provided below. CEPA The CEPA aims to reduce or eliminate tariffs over next 10 years on over 90 per cent of goods traded between the two countries. The Agreement inter alia provides ‘schedule for India’, a list detailing product wise plan for reduction/ elimination of duties for imports into India and a similar ‘schedule for Japan’. The quantum of duty reduction under CEPA will vary from product to product. Therefore, some products may see a complete elimination of duties on 1 April 2011 itself (or any other day on which the Agreement comes into force) while others may see a gradual reduction over years. Sensitive sectors for India and Japan are fully protected and will not see any tariff change. An illustrative list of goods for import into India and the time period over which basic customs duty would be eliminated is given below: |Description of goods |Period in which tariff to be reduced...
