NO MORE WOOF http://www.livescience.com/42300-no-more-woof-dog-animal-communication.html A dog may be man’s best friend‚ but if people ever figure out what dogs are really thinking‚ will the friendship sour? That’s a risk that a few inventors in Europe are willing to take: They’ve received funding to develop "No More Woof‚" an electronic device that promises to analyze dogs’ brain waves and translate a few of their thoughts into rudimentary English. It’s still a work in progress‚ but once

at different pHs Abstract These experiments aimed to determine the optimum pH ranges various buffers are effective and provide opportunity for the use of the Henderson-Hasselbalch equation to prepare a buffer of a specific pH. Three different buffer systems were initially investigated; volumes of weak acid and weak bases of specified concentration were prepared and titrated against strong acid or strong base solutions with pH readings taken at frequent intervals to determine pH ranges over which

Factors Affecting Enzyme Activity Abstract: In the following lab factors affecting enzyme activity‚ temperature‚ pH‚ enzyme concentration‚ substrate concentration and surface area will be tested on a beef liver enzyme to see if there will be any effect of performance. By doing 2 or more trials the results will show whether there is an effect to the enzyme from the following factors or not. Some of the factors may denature the enzyme and some will do nothing. Using a table qualitative and the

form and propagate are: The presence of a local plastic stress; The presence of a tension stress; The presence of a cyclic stress (repeated or fluctuating). Eliminating any one of the above three requirements will stop the fatigue process. 2. Describe the three stages of fatigue in metals. The three stages of fatigue in metals are: Stage 1: Crack Initiation – Movements of dislocations resulting into slip line and slip planes. It will begin at the point where the local tensile is a maximum.

Finding the Optimal pH of the Enzyme Peroxidase with the Aid of a Spectrophotometer ABSTRACT The peroxidase enzyme was partially purified‚ and the enzyme activity was calculated with the use of a spectrophotometer‚ demonstrating the effect of pH on peroxidase activity. The objective of this exercise was to determine the ideal pH for peroxidase activity. The data concluded that the optimum pH for peroxidase activity is 5‚ and the “standardized” enzyme volume is 2.8mL

Enzymes are catalytic proteins that selectively speed up chemical reactions without by consumed by the reaction itself (1). Enzyme activity is significantly affected by factors such as temperature‚ substrate concentration‚ enzyme concentration and pH. Enzymes are highly specific and only catalyse one specific chemical reaction‚ speeding up the reaction by lowering the activation energy‚ the energy required to start a chemical reaction (2). At high temperatures and with various mechanical forces or
