Kristen Magliola 9/9/13 BIO: 414L Lab Report: SOC Medium I. Purpose: To make liquid and solid media for microbial growth II. Background: There are four different types of media used to grow microbes. They consist of Enriched media‚ Nutrient media‚ Selective media‚ and differential media. Enriched media is a growth media supplemented with complex biological molecules. This type of media is used for blood‚ coagulated blood‚ amino acids‚ etc. Nutrient media provides nutrients necessary

that can be met by conventional energy sources. The solution to long term energy source is the nuclear powered batteries which have a life span of few decades and can pack in energy densities thousands of time greater than conventional battery sources. Hence‚ there is an urgent need to harvest enormous amount of energy released naturally by the tiny bits of radioactive material. Unlike conventional nuclear power generating devices‚ these batteries do not rely on the fission or fusion reactions and

Nuclear energy originates from the splitting of uranium atoms in a process called fission. At the power plant‚ the fission process is used to generate heat for producing steam‚ which is used by a turbine to generate electricity. Nuclear energy usually means the part of the energy of an atomic nucleus‚ which can be released by fusion or fission or radioactive decay. What are the Benefits of Nuclear Energy Nuclear energy is the world’s largest source of emission-free energy. Nuclear power plants

Experiment I: Thermochemistry Background: Thermochemistry is the branch of chemistry that focuses on the studies of chemical reactions or physical changes and heat associated with chemical reactions. According to the first law of thermodynamics‚ energy cannot be created or destroyed but it can be converted from one form into another and/or transferred between different atoms‚ molecules‚ or substances. In general‚ energy can be classified into two categories: kinetic and potential. Kinetic energy
