While these are great way to solve a case there’s another kind of evidence; trace evidence. Trace evidence are small pieces of evidence that are laying around a crime scene. There are many types of trace evidence some of them include metal filings‚ plastic fragments‚ gunshot residue‚ glass fragments‚ feathers‚ food stains‚ building materials‚ lubricants‚ fingernail scrapings‚ pollens and

The Rise of Antibiotic-Resistant Infections by_ Ricki Lewis‚ Ph.D._ When penicillin became widely available during the second world war‚ it was a medical miracle‚ rapidly vanquishing the biggest wartime killer--infected wounds. Discovered initially by a French medical student‚ Ernest Duchesne‚ in 1896‚ and then rediscovered by Scottish physician Alexander Fleming in 1928‚ the product of the soil mold Penicillium crippled many types of disease-causing bacteria. But just four years after drug

Bacterial are very diverse and quite adaptable‚ but they still need certain factors in order to thrive. The physical requirements for bacterial growth include pH range‚ temperature‚ oxygen concentrations‚ moisture levels‚ hydrostatic pressure‚ osmotic pressure‚ and radiation levels. When considering the pH level‚ bacteria are classified as either acidophiles (acid-loving)‚ neutrophiles (neutral ph range)‚ or alkaliphiles (alkali-loving). The one that causes disease in humans would be the neutrophiles

Unit 3. Assignment 1: Bacterial Growth Rates 1. Mediums that could be used to determine shigellosis include Btilliant Green Agar‚ and Triple Sugar-Iron Agar. Expected results in a confirmed case of shigellosis are as follows: Brilliant Green Agar – Isolated Shigella colonies which do not ferment lactose or sucrose and appear red or white in color with no growth to trace growth on the Agar plate will be present. Triple Sugar-Iron Agar – Presence of Shigella will manifest as a red slant with

Brenda Lainez REL 2011 September 26‚ 2012 Assignment #1 The Case of Contamination The author‚ Kwame Anthony Appiah‚ starts the essay‚ The Case of Contamination‚ by describing the veranda of a palace in Ghana. His description paints a vivid picture of a place full of custom‚ color and tradition. However‚ he presents a contrast by describing that some of the people were dressed in western suits‚ sporting cell phones and having business meetings. This place is a mixture of tradition and

But‚ reflecting on that is there anything‚ which is really original and free from Appiah’s "contamination"? How are we to champion human innovation whilst trying to maintain and preserve cultural heritage and where do we draw the line? Also‚ who

A General Review of Tetracyclines Antibiotics Chang Liu Instructor: Prof. Jasson Sello Department of Chemistry‚ Brown University Providence 02906‚ RI Tetracyclines are the first broad-spectrum antibiotic to be applied to clinic use. Nevertheless‚ the increasing incidence of bacterial resistance of tetracyclines led to a series of studies on the development of semisynthetic tetracyclines to circumvent the resistant organisms. In order to better design the structures of tetracycline derivatives

There were eight antibiotics used for this experiment; chloramphenicol (C)‚ erythromycin (E)‚ fusidic acid (FC)‚ oxacillin (OX)‚ novobiocin (NO)‚ penicillin G (PG)‚ streptomycin (S)‚ and tetracycline (T). The mode of action of Chloramphenicol is the inhibition of protein synthesis. Chloramphenicol irreversibly binds to a receptor sit on the 50S subunit of the ribosome on the bacteria that inhibits the enzyme peptidyl transferase. This inhibition results to the prevention of the transfer of amino

A gene is a sequence on DNA that has a specific region on the chromosome‚ which determines a particular characteristic in an organism. For many years it has been thought that there are specific genes responsible for certain behaviour and so there is a gene for criminal behaviour. In the first half of the twentieth century
