How to Calculate Beta Beta refers to the volatility of a particular stock compared against the volatility of the entire stock market or‚ in practice‚ a representative index of that market‚ such as the Standard and Poor ’s (S&P) 500. Beta is an indicator of how risky a particular stock is and is used to evaluate its expected rate of return. Beta is one of the fundamentals stock analysts consider when choosing stocks for their portfolios‚ along with price-to-earnings ratio‚ shareholder ’s equity

Title: Investigation of Induction Time of lac operon in E. Coli with IPTG‚ and Comparision of the Amount Beta-galactosidase produced with Lactose‚ IPTG and Antibiotic. Abstract: Introduction: An operon is a group of genes that are arranged side by side with a regulatory gene. It also includes a promoter gene‚ operator gene‚ structural genes. Regulatory genes control transcription with positive or negative signal. (Jacob‚ and Monod‚ 1961) A positive signal‚ inducer‚ would stimulate

After the discovery of isotopy by Frederic Soddy and Kasimir Fajans‚ it was found that elements considered to be non-active may possess radioactive isotopes having almost identical chemical properties [1]. Radioisotopes are atoms with a nucleus that is seeking a more stable configuration by emitting radiation. Scientists have learned that more radioisotopes could be created by subjecting certain elements to radiation inside a nuclear reactor or bombarding them using a particle accelerator

alleviate symptoms without halting disease progression. Amyloid beta peptide polymerization is considered to be one of the hallmarks of Alzheimer’s progression within the brain. Therefore‚ by developing treatment strategies to inhibit the aggregation of amyloid beta peptides‚ there is potential to inhibit the progression of Alzheimer’s disease beyond traditional approaches‚ such as acetylcholine replacement therapy. One means of inhibiting beta amyloid plaque formation is through the sequestering of copper

familiarity to the physics lab. Objectives Group 7 was instructed to observe the absorption of beta particles when passing through different thicknesses of polyethylene absorbers. This also helped group 7 practice how to use basic instrumentation of nuclear physics. Procedure It was necessary to determine the operating voltage for the G-M counter. Group 7 put the beta source right underneath the sensor and started with a voltage of 200 V‚ then slowly added more and more voltage

Hypertensive heart disease is obviously caused by high blood pressure. High blood pressure means the pressure inside the blood vessels‚ which is arteries is too high. As the heart pumps‚ it must pump against the pressure‚ so it must work harder. Gradually‚ the heart muscles will be thicken. Sometimes it does not get enough oxygen because the muscle is too thick. It influenced your heart to pump regularly and its functions. These changes could effect the thickening and enlargement of the heart (left

Fourth-generation cephalosporin Mechanism of Acton Bactericidal: inhibits synthesis of bacterial cell wall‚ causing cell death. It is the best beta-lactam for IM administration; has poor capacity to cross blood-brain barrier and thus is not used for treatment of meningitis Cephalosporins exert bactericidal activity by interfering with bacterial cell wall synthesis and inhibiting cross-linking
