coronavirus in samples taken from six patients. The CDC‚ however‚ noted viral particles in affected tissue (finding a virus in tissue rather than secretions suggests that it is actually pathogenic rather than an incidental finding). Upon electron microscopy‚ these tissue viral inclusions resembled coronaviruses‚ and comparison of viral genetic material obtained by PCR with existing genetic libraries suggested that the virus was a previously unrecognized coronavirus. Sequencing of the virus genome

TITLE OF PROJECT: Effects of Chemoattractants of Pseudomonas Aeruginosa Through a Capillary Tube. PROPOSED COST: $1764.90 ABSTRACT: This project will show how strong certain bacteria that are commonly found in biofilms attract to Pseudomonas aeruginosa through a capillary tube. It will test ten bacteria to see which bacteria have more chemoattractants with Pseudomonas aeruginosa . These bacteria are all motile‚ so to come together to form a biofilm‚ they must lose their ways of

Microscope Microscopes are instruments that produce a magnified image of a small object. They are used in many scientific and industrial applications. Some common applications for microscopes include manufacturing inspection and high-technology quality control. Specific quality control applications for microscopes include semiconductor processing‚ medical imaging‚ cell research‚ and metallurgical analysis. Microscopes are supplied in one of three common configurations‚ student‚ benchtop‚ and research

How was the Microscope Invented? The microscope is a machine used to see tiny‚ small things such as germs and bacteria. These small creatures are not seen by us but can be seen by a microscope. The three subtopics that will be mentioned are: 1) Who invented the microscope? 2) Why was it invented and What are the different types of microscope. The prediction made was that the microscope was a very important part of life in the middle-ages. People had very serious sicknesses at that

Period B 10/4/13 I. Title: Microscope Lab Report II. Purpose: The purpose of this lab was to teach us how to use a microscope‚ how to make a temporary wet mount‚ and how to stain a slide. The purpose of this lab was also to teach us how to use and measure with a microscope. The purpose of this lab was also to teach us how to draw what we see in a microscope’s field of view. III. Procedure: A. How to use a Microscope When going to take out the microscope‚ make sure you carry it back to

Second-harmonic generation (SHG) imaging technique‚ combined with confocal fluorescence microscopy (CFM) revealed that PHBHHx in PHB scaffold provided better surface properties for anchoring type II collagen filaments and their penetration into internal layers of the scaffolds.
