Judson Cotterman III 4/6/2012 Section 185-35L Assignment #3 Gram-positive Pathogenic Cocci Discussion My original hypothesis for the individually collected throat culture on Blood Agar Plates‚ that it would show a mixture of alpha‚ beta‚ and gamma hemolysis‚ was based on the results of the class control samples of S. pneumonia‚ S. aureas and S. epidermis. In these controls S. pneumonia shows alpha and beta hemolysis while S. aureas and S. epidermis showed beta and gamma hemolysis respectively.

Gram Staining Lab Introduction Gram staining is a very important technique used in biology labs all over the world. It is a technique used to differentiate types of bacteria using certain physical and chemical characteristics of their cell walls. Gram positive bacteria (which show up purple after the gram staining process) have a very thick layer of peptidoglycan where gram negative bacteria (which show up pink after the gram staining process) have a much thinner layer of peptidoglycan. One thing

Han and Roman Empires The Roman Empire existed between 31 B.C.E to 476 C.E. and the Han Dynasty occurred 202 B.C.E. to 220 C.E. They existed at same times but were on opposite ends of Eurasia. They both had regions that were ruled by either kings‚ viceroys or governors in the name of the emperor. They were both similar in slavery‚ government‚ and their downfall. They also had their differences in religion‚ military‚ and center of power. Both civilizations had very strong central governments

agency NASA selected Gram Power’s technology among the top-10 cleantech innovations from around the world. Two fresh graduates from the University of California Yashraj Khaitan and Jacob Dickinson founded GRAM POWER which enables villagers to generate and store renewable energy from biomass‚ solar or wind on-site. While on a university project they came to know about the scarcity of electricity in villages‚ this goaded them to devise energy solutions for villagers. This year‚ Gram Power set up India’s

The Roman Empire and the Han Dynasty of China were great empires that still have influence on us today. As they developed‚ they formed some similarities in government‚ but there are more obvious differences between them in religion and commerce. The Roman empire and Han Dynasty both had a great leader who led them to their Golden Ages. In China‚ the emperor Wu Ti significantly expanded Chinese territory from Central Asia to Manchuria and Korea to Northern Vietnam‚ establishing the Pax

IDENTIFYING GRAM POSITIVE COCCI As mentioned in Exercise 8‚ “Identifying Gram Negative Rods”‚ identifying bacteria is a common activity in the microbiology lab. Like the game Clue™‚ each time you gather a piece of information to solve the mystery‚ you gather some information that supports some identities and eliminates others from contention. In the lab‚ the process continues as you gather more information until only one microbe remains and all others have been eliminated as possibilities. Thus

An Age of Empires: Rome and Han China‚ 753 B.C.E.-330 C.E. Key Terms: 1. Roman Republic: The period from 507 to 31 B.C.E.‚ during which Rome was largely governed by the aristocratic Roman Senate. 2. Roman Senate: A council whose members were the heads of wealthy‚ landowning families. Originally an advisory body to the early kings‚ in the era of the Roman Republic the Senate effectively governed the Roman state and the growing empire. Under Senate leadership‚ Rome conquered an empire

Differentiating Organisms using the Gram Stain Introduction The experiment conducted was based upon the known attributes of two different groups of bacteria‚ those that are gram positive‚ and those that are gram negative. Using a specific staining procedure‚ it is possible to differentiate the two types under a microscope The gram stain method of differentiation is possible because of differences in the cell membrane between the two categories of bacteria. Gram positive cells have an extra thick

Hank Kolb‚ Director‚ Quality Assurance Problem Definition The fundamental problem is management. Senior management lacks the policies and visible support of a quality philosophy such as following a ISO 9000 Quality System. Even though they have recently appointed Hank Kolb to oversee their quality program‚ which is a move in the right direction‚ there is still a lack of visible senior management support for quality. The fundamental problem shows up in a number of symptoms such as putting schedule
