Abstract The aim of this study was to test the rate of reactivity of the enzyme catalase on hydrogen peroxide while subject to different concentrations of an inhibitor. The hypothesis was that hydrogen peroxide will be broken down by catalase into hydrogen and oxygen‚ where a higher concentration of inhibitor will yield less oxygen‚ resultant of a lower rate of reaction. Crushed potato samples of equal weight were placed in hydrogen peroxide solutions of various temperatures. The results showed

ABSTRACT Fly Ash is a supplementary cementitious material (because of its pozzolanic character) for cement concrete. It is widely available and technically highly useful product. The cement contents‚ Fly Ash Concrete are more durable; actually durability level of Fly Ash Concretes can not de achieved in cement concretes. These aspects‚ besides‚ various benefits of usage of fly ash in cement concrete are discussed in this paper. It is concluded‚ based on the available information‚ that there is no

Notes on histology Histology Lecture 1 Histology is the study of tissues: in our case‚ it means study of tissues which make up the human body. Tissue is defined as a group of cells which perform a common function. All the cells in a given tissue are not necessarily identical or similar e.g. blood is a type of connective tissue but it has many different types of cells. However‚ tissue also contains two other components i.e. ground substance (or matrix) and fibres. Despite the complexity of

the highest concentration of salt to see if it will harm the grass. First‚ thing is to get all the equipment needed to perform this experiment. I will need three round flower pots 1 inch in diameter and height. I will be using ¼ cup of ammonium sulphate fertilizer and ½ cup of sodium chloride concentrations salt‚ rock salt (halite)‚ and calcium magnesium acetate salt (Peeples‚ 1990). The last and final ingredient I will need is three different types of grass sod‚ St. Augustine grass‚ Bahia grass
