By Jonas Wilson‚ Ing. Med. Causes of Ureteric Calculi Ureterolithiasis or ureteric calculi are stones that are present in the ureters‚ which are the muscular tubes that connect the kidneys to the urinary bladder. These tubes are physiologically constricted at 3 points along their lengths‚ namely at the ureteropelvic junction‚ entry into the pelvis as they cross the bifurcation of the common iliac artery and the ureterovesical junction. As a consequence‚ these points are the commonest sites where

SYNTHETIC EXPLOITATION OF ENZYMES: BIOCATALYSIS IN ORGANIC SOLVENTS: FUNDAMENTALS ENZYMES IN ORGANIC SYNTHESIS 1. Enzymes catalyze a broad spectrum of reactions with high turnover numbers. Rate enhancements approach 1012 fold. 2. Enzymes may accept a wide range of substrates. 3. Enzymes are highly regio and stereoselective. 4. Enzyme reactions take place under mild conditions; this minimizes problems of isomerization and racemization. 5. Enzymatic processes are less hazardous and polluting

The Nitrogen Cycle Nitrogen fixation Atmospheric nitrogen must be processed‚ or "fixed" to be used by plants. Some fixation occurs in lightning strikes‚ but most fixation is done by free-living or symbiotic bacteria. These bacteria have an enzyme that combines gaseous nitrogen with hydrogen to produce ammonia‚ which is then further converted by the bacteria to make their own organic compounds. Conversion of N2 The conversion of nitrogen (N2) from the atmosphere into a form readily available

The tube that contained my unknown material was tube number twenty. I did a gram stain‚ oxidase test‚ and used three different medias to narrow down and identify my unknown organism. The first step I took in identifying was a gram stain. This gram stain would reveal whether my organism is gram positive or gram negative which would narrow my choices from fifteen options down to six. After completing the gram stain‚ my unknown was the color pink. This revealed my unknown as being gram negative.

In this lab we used a solution of lactase to test the chemical and physiological properties of this particular enzyme and determined whether the lactase came from human cells or bacterial cells. In the statistical analysis statistical formulas and techniques are used to analyze the significance of a set of data and the validity of the conclusions made based on that data. These are some terms and definitions that will be crucial to understanding the validity of this experiment. An enzyme is a protein

product and raise the milk’s pH. Other bacteria such as lactobacillus and Streptococcus ferment lactose to lactic acid and acetic acid. Those acids sour the milk and convert the casein in milk to curd. The sour or putrid smell of milk is caused by Pseudomonas and Achromobacter. In small scale community such as in a container of milk‚ the community succession is examining through the presence of bacteria. In this exercise‚ we observe the physical change of milks at different conditions and identify
