Influence of Heat Treatment on Hardness and Corrosion Resistance of Commercial Aluminium Mayeedul Islam 1‚*‚ S. M. Najmul Hoque2‚ M. Abdullah Al Mahmood2‚ A. A. Shisir 2 ABSTRACT Aluminium and their alloys are widely used as construction materials from house hold appliances to air-craft parts. The commercially pure aluminium has merely low corrosion resistance and hardness compare to aluminium alloy. In this study an attempt has been made to study the influence of heat treatment on the properties

An integrated study of the Mpenjati estuary-beach system. (Biological component) Abstract A study was carried out to find the abundances of animal organisms between both sides of the Mpenjati estuary. Zooplankton‚ Macro fauna‚ Meiofauna and Fish was sampled .Each of the species that reside in the estuary contribute to the diversity of the area and are essentially driving forces‚ ensuring optimal functioning of the ecosystem. The purpose of sampling such ecosystems is to find out how the interactions

Complexometric Determination of Water Hardness Mike Monaghan CHM 152LL 01/27/2013 Abstract: What can be found from this experiment is as follows‚ Introduction/Background: This lab was about determining water hardness. Water hardness is the amount of metal ions in the water. The most common found ion in the water is calcium ions and typically with a charge of +2. Water hardness plays a big significance in our daily life because to many metal ions in our drinking water can have adverse effects

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

ABSTRACT The quality of pipe borne water supplied by Imo State Water Corporation has been assessed by analyzing samples of water collected from different locations for their physicochemical parameters and bacteriological quality. The observed values were compared with standard values given by the World Health Organization for potable water .The quality of the analyzed water is found fit for human consumption.

topic of tap water and bottle and why you should drink tap water. What are the types of waters and the facts of bottled water and tap water? What are the standards and regulations over bottled and tap water? Why you should drink tap water? Based on research I believe that tap water is a better choice because of the FDA regulations and standards places on it‚ the effect it has on the environment and the overall cost and health effects of tap water. Tap Water Vs Bottled Water What are the

It is no secret that bottled water costs more than tap water‚ but is it reasonable to state it costs 1‚000 times more? It is very difficult to give an exact number for the difference between the two‚ but 1‚000 to 2‚000 times more is a reasonable estimate. This is based on the fact that on average‚ a gallon of bottled water costs $1.22. Protesters against bottled water industries use the highest prices of water bottles they can find as a way to show a bigger contrast between the two‚ essentially

Water Protection In 2011 Water Quality Annual Report of Seattle‚ I find good news: Seattle’s tap water continues to be some of the best in the nation. (“Water Quality‚” 2011) When I first came to Seattle‚ I realized that the taste of water in Seattle was different from my country. That confused me for a long time until I saw the report and helped me to confirm water quality in Seattle was good. From my own experience‚ I firmly think the water quality in America is better than in China generally
