Introduction In my report I will discuss what I did as an experiment and what I hope for it to achieve. Firstly I carried out an experiment to assay the effectiveness that a range of disinfectants have on the growth of ecoli and whether or not it can prevent it from growing. From the experiment i should be able to see that some disinfectants have a greater effect than others do. From this I shall then draw a conclusion and evaluation on what was the most effective‚ and could there have been any

I. Introduction Aggregates contribute to 60-80% of a concrete mix‚ with water and cement being the other major constituents. Therefore considerable testing and consideration should be placed on aggregate type and size to ensure an adequate concrete mix. Two tests have been performed to establish the properties of the aggregates: 1. Compacted bulk density test 2. Sieve analysis II Testing For Compacted Bulk Density Objectives * To determine the specific bulk densities of a range

The effect of water and fertilizer on corn seedlings Biology 1108 Lab Section November 7‚ 2012 Abstract The effect of water and fertilizer on corn seedlings was examined. It was hypothesized before the experiment that enough water with sunlight and air should make the plants grow healthy. It has to do with photosynthesis. Fertilizer is also going to make the plants grow much faster; this is because of the nutrients in it. The experiment took about four to six weeks to complete; it took some

The aim of the experiment was to examine the effects of consuming lactate before and during a prolonged exercise. The data shows that the consumption of the lactate actually did work and the performance of the subject was better than the previous three experiments of dieting. This was due to the lactate that was consumed in the CytoMax. Azevedo‚ Tietz‚ Two-Feathers‚ Paull‚ and Chapman (2007) state that CytoMax contains polylactate which speeds up the delivery of substrates and is thought to help
