It is hypothesized that as the substrate concentration increases‚ the rate of reaction will increase respectively‚ until the enzyme reaches its optimum point of saturation‚ after which any increase in the substrate concentration will no longer affect the rate of reaction. The independent variable in this investigation is the varying concentrations of the substrate (Hydrogen Peroxide: 1%‚ 3%‚ 5% and 6%)The dependent variable was the rate of enzyme catalase activity‚ which was measured by the volume

point where the retrieval accuracy becomes saturated. Experimental results show that the proposed method yields higher retrieval accuracy than some conventional methods even though its feature vector dimension is not higher than those of the latter for six test DBs. Especially‚ it demonstrates more excellent retrieval accuracy for queries and target images of various resolutions. In addition‚ the proposed method almost always shows performance gain in precision versus recall and in ANMRR

role in the construction of the roads and the aqueducts‚ and developed many of the fundamental principles of surveying and construction. Essential to every engineering project‚ presently as well as in ancient times‚ was the need for consistency and precision in measuring. The use of measuring equipment assisted the surveyors in this endeavor and was essential in the Romans’ ability to build on a grand scale. Some methods were less precise than others‚ ranging from the use of pacing and ropes to standardized

The pyramids of Egypt were one of the most influential pieces in ancient Egyptian society. The pyramids were the royal tomb and place of accent for a deceased Pharaoh spirits. From the top point of the pyramid‚ it was thought‚ the soul would travel to the afterlife of the Field of Reeds and‚ if it so chose‚ could easily return to earth. Pyramids in the early dynasties were built as temples for the priests and nobles to worship the gods. Many people today think that the Pyramids are just tombs for

Precision and confidence: Precision refers to closeness of the findings to “reality” based on a sample. It reflects the degree of accuracy or exactitude of the results on the basis of the sample to what it really exists in the universe. Confidence refers to the probability that the estimations are correct. 6. Objectivity:

Answer: Electronic balance features including electronic read-out and the tare. Electonic balance can measure mass to the precision of 0.0001. Electonic balance has the tare feature which resets a balance to zero in order to get the weight of the sample‚ and not the container of the sample. It has enclosed glass to contain the substance being measure (Thinkwell‚ 2012). (b) (1
