...present of lipid in food samples using brown paper. Introduction : We had learned about that all living organisms are made up of molecules, each molecule serve its own special purpose. Molecule can be divided into two types, macromolecules and micro molecules. The molecules that we are studying in this experiment are macromolecules. In this case, we are studying on 3 types of macromolecules, carbohydrates, protein and lipid that present in different food. Carbohydrate can be divided into monosaccharide, disaccharide and polysaccharide. Monosaccharide is the simplest sugar that appears in food, the most common example of this is glucose. Disaccharide is a double sugar, which means by it linked two monosaccharides together to form a disaccharide. The examples for disaccharide are maltose, galactose and sucrose. The example of polysaccharide is starch. Protein is build up by the monomers, amino acid. Each protein has it own special sequence that is different from others. The Biuret reagent is used to determine the presence of protein as it turns the original blue colour of the solution to purple when it react with the protein, specifically between the bonds of amino acid. Lipids are oily or greasy in nature and it is insoluble in water. It only can be dissolve with organic solvent such as ether or chloroform. It can store energy in the cell for long term usage. Its presence can be tested by rubbing some food samples on a brown paper and hold under the light. Materials : ...

...To know when you were going to die would be horrifying but not knowing would be just as horrifying. This would be a very important decision to make. If I were in that situation, I would probably choose to turn over the paper and accept my death. My first reason why I would turn over the paper would be, making the most of what you have left. You would be able to make the most of what is left of your life and spend it all up to the last second you have left. You could use the time to spend time with your family and do fun things for the last time with them.

...Political Science 1101 American Government Fall 2014 Dr. Joshua Kennedy Reflection Papers Each student is required to select ONE (1) of the course’s three main sections (Political Fundamentals, Political Institutions, and Political Linkages) on which to write a reflection paper. This paper will count for 75 of the total 350 points in your final course grade. It should be between 3 and 4 double-spaced pages (1 inch margins, Times New Roman, 11 or 12 point font). The purpose of the paper is to encourage you to think about what the section’s material conveys about American government and politics and what questions it raises for you. The most important skill to demonstrate in these papers is the ability to think critically. It is obviously good to know the material you have read and studied, but you should not simply be parroting back what is written in the textbook. Your paper ought to consider why these topics are grouped together in this manner, what gaps in knowledge remain, and your personal reflections on these questions. There are numerous ways to approach the assignment. To give you some idea of how you are going to be evaluated, a paper focusing on the first section of the course (Political Fundamentals) might focus on how theories and structures in the Constitution are more or less relevant to politics today. For example, your textbook implies that the Senate as an institution might be outdated – such a subject could make for interesting discussion based on your understanding...

You are in the room for one hour only and can never return to it. Tell if you would turn the paper over and read it and why/why not? I wouldn’t know to turn the paper over. I would say no, then change my mind to maybe. I have lots of different reasons on how I would make my decision. The first thought I would have would be no. I say no because then I would always be focused on the day. I would be scared and tell myself only (numbers of days ) until I die. I would also spend a lot of time thinking about how I would die. I know that I wouldn’t get anything done because it would always be on my mind. I also would be very paranoid. I would react like it’s the end of the world. I probably wouldn’t go anywhere because I would be afraid of dying. I would go mentally crazy just thinking about the date. I would also spend all my time thinking about God and getting...

...research paper on an individual that had a great impact on Black History.” As soon as I heard the announcement, my heart beat increased and my palms began to sweat. Literally, I dropped my face on my desk and whispered, “God help us all; I’m about to fail this class.” I had a gut feeling that the assignment was going to be difficult and time consuming. Immediately I imagined the many hours that I would have to assert on the assignment, and the thought depressed me. Little did I know that doing the assignment would bring me one of the greatest surprises of my academic life and taught me that the writing process can’t be rushed. Mrs. Fisher paced back and forth in front of the class room as she explained how someone inspired her to become a teacher. At some point I stopped listing and was on the verge of dozing off. Suddenlty my attention snapped back to her as her words “I get to assign you the person to do this essay on” pushed themselves into my consciousness. Up this point I had thought that we can pick our own person and had settle on Martin Luther King, Jr. Mrs. Fisher proceed to assing different historical figures to different students while the fear of not getting MLK creeped over me. Finally, Mrs. Fisher said,”Santiago Torres, MLK.” For the first time in that class, I felt hopeful. 3 days later we had the rough draft due about our person. Well I didn’t do as you can imagine. Walked into class with this guilt feeling that we all get after we don’t do a paper on time. She...

...Fax: (949) 824-8385 E-mail: hyunmyuk@uci.edu Abstract : Existing k-shortest path algorithms has some weaknesses such as path similarity among determined paths and network expansion for describing turn prohibitions. Path similarity represents that many of the alternative paths derived from the k-shortest path algorithm are likely to share a lots of links, so they could not represent heterogeneity. The turning restrictions popularly adopted in real road may violate Bellman’s principle of optimality in searching shortest path, so network expansion technique is widely used to avoid such difficulty. But, this method needs additional works to expand the network. This paper proposes a link-based shortest path algorithm to generate dissimilar paths for the travel information in real road network where exists turn prohibitions. The main merit of proposed model is to provide efficient alternative paths under consideration of overlaps among paths to alleviate the path similarity. Another merit is that it does not require extra nodes and links for expanding the network. Thus it is possible to save the time of network modification and of computer running. The algorithm is tested with some example networks and then will be expanded to a dynamic case. Key Words : dissimilar path, path overlap, turn prohibition, link-based algorithm, k-shortest path 1.

...Key Supply Chain Performance Indicator Paper Danny Shieh ISCOM/370 March 31th, 2012 Leon Powell Key Supply Chain Performance Indicator Paper The success of a company can often be represented by its performance of the supply chain element. Such performance is measured to ensure the flow and process of each element is accurate and up to standard based on the company’s goals and objectives. In this paper, author will first define supply chain and its elements, then define the meaning and importance of key performance indicators. Lastly, Author will explain three example indicators, how it is calculated, and what the number means. Supply Chain Management Supply chain management (SCM) is defined as managing the flow of information and materials from upstream suppliers to downstream customers. The Institute for Supply Management’s definition states that “Supply chain management is the design and management of seamless, value-added processes across organizational boundaries to meet the real needs of the end customer” ("Institute for Supply Management", 2011). The elements of the supply chain are components that made the flow possible. Such element includes supplier, logistics/transportation, purchasing, production, inventory, planning, IT, quality assurance/quality control, and customer. These elements are important to the flow of supply chain as they each contribute a function that worked together...
