Laboratory Report: Observing Bacteria Purpose: Is to gain knowledge on how to use a microscope and oil immersion lens while observing prepared bacterial slides and also to prepare slides for observable bacteria culture from yogart. Procedure: Exercise 1: Using the Microscope - Viewing Prepared Slides I started out by reading and reviewed the science lab safety reinforcement Agreement and the instruction to oil immersion lens. After setting up my lab station I view the six prepared slides

Q1. A researcher wishing to estimate the proportion of X-ray machines that malfunction and produce excess radiation. A random sample of 40 machines is taken and 12 of the machines malfunction. The problem is to compute the 95% confidence interval on π‚ the proportion that malfunction in the population. Solution: The value of p is 12/40 = 0.30. The estimated value of σp is = 0.072. A z table can be used to determine that the z for a 95% confidence interval is 1.96. The limits of the confidence

method of observation of a living organism is smeared on a slide with one stain during a procedure. A wet mount is where a research method of an organism or organisms is placed on a slide with fluid. The microorganisms can then move freely. On the laboratory research completed January 30‚ 2006 using a wet mount example and a simple stain instruction the following items were used to obtain the visibility of microorganisms moving through slides using two kinds of avenues. The first was a wet mount. The

The University of Hong Kong Department of Civil Engineering CIVL2002 M – Geology & Rock Laboratory Report Brazilian Test A. Introduction As shown by the Griffith criterion‚ tensile strength of brittle materials is theoretical 1/8 of the compressive strength. Typically‚ tensile strength of rock materials is about 1/10 to 1/8 of the compressive strength. Hence‚ rock fails easily under tension. In design‚ rock should be subjected to minimum tensile stress. Several methods

Abstract This report is to highlight the methods‚ results and theory relevant during an engineering experiment called “cold rolling of metals". The purpose of this report is to show how readings obtained from the set-out experiment‚ can be evaluated to determine the behavior of 3 selected materials; Brass‚ Copper and Aluminium through the process of cold rolling. The form of the materials are in small strips which are processed via cold-rolling method 4 times from their original state to evaluate
