Preparation of Fruit Flavors (Pear) Abstract. In this experiment an assigned Ester is prepared‚ particularly n-Propanol. The Preparation was done via Fischer reaction. In this reaction‚ a reflux set-up is required. The reflux set-up was used in the liquid-liquid extraction. After adding an immiscible solution to the compound containing n-Propanol‚ the mixture now will have two layer: the Organic and Aqueous layer. The organic layer is the extract needed and its % yield is computed resulting to

However‚ these effects can vary greatly‚ with some species being affected greatly‚ and others not at all. For example‚ UV-B radiation can cause the skin of Gray Tree frogs to darken‚ and cause them to swim less. For others‚ like the Pacific Tree frog‚ this radiation can reduce larval survival and increase abnormalities in behavior and development. Other common effects include increased embryo mortality and behavioral avoidance. Interestingly‚ different populations of amphibian species can be differently

The Old Man and the Sea The Old Man and the Sea by Ernest Hemingway depicts the dismal reality of life’s cruelty‚ portraying how circumstances sometimes have inevitably dire outcomes regardless of the precautions we take or the effort we exert. But though the depravity of life controls our fate‚ it doesn’t determine our intestinal fortitude. Santiago was an extremely diligent and hardworking man. Day in and day out‚ rain or shine‚ he worked diligently and vigorously at the only trade he had ever

Good Practice Guidance and Uncertainty Management in National Greenhouse Gas Inventories N2O EMISSIONS FROM ADIPIC ACID AND NITRIC ACID PRODUCTION A C K N O WL E D G E M E N T S This paper was written by Heike Mainhardt (ICF Incorporated) and reviewed by Dina Kruger (USEPA). ABSTRACT Nitrous oxide (N2O) is generated as a by-product during the production of adipic acid and nitric acid. The main use for adipic acid is as a component of nylon-6/6; thus production trends are closely correlated

Regenerative Medicine Regenerative medicine is the process of creating living‚ functional tissues to replace or repair tissue or organs that are damaged. This is a relatively new process and can promote rejuvenation in previously irreparable organs. The process begins by taking adult stem cells from a damaged organ or tissue sample‚ and combining them with an organic structure so the cells may replicate the organ or tissue that they originated from. Each cell has its own chemical make-up which

Research Project: Potato The potato originated in the South American Andes‚ but its heartland of wild genetic diversity reaches from Venezuela‚ Colombia‚ Ecuador‚ Peru‚ Bolivia‚ Argentina‚ Chile‚ Uruguay‚ Paraguay‚ southern Brazil‚ northward into Central America‚ Mexico‚ and the southwestern United States. Potato was first cultivated between 3 and 7 thousand years ago‚ some scientists believe they may have grown wild in the region as long as 13‚000 years ago. Potato is the third most important

Terminating Nutrition and Hydration: Controversial Issues Nurses deal with moral and ethical issues daily. As health care advances with changes in legal and social issues‚ medical technology‚ and patient ’s rights‚ more ethical concerns will arise. Nurses must learn how to respect their patients by recognizing an individual ’s preference; therefore‚ granting them autonomy. According to Blais‚ Hayes‚ Kozier and Erb (2006)‚ "Autonomy refers to the self-determination and the right to make one ’s
