Heavy metal contamination occurs though all facets of life such as air‚ water‚ food‚ soil‚ and in everyday objects and occurrences. When heavy metals enter the air from factories emissions and smoke‚ it is exposed to the body‚ which mostly affect your skin and lungs such as Cadmium and Arsenic. Common water contaminates are Chromium and Thallium‚ Chromium can enter the water source usually through spills and leaks from power plants. Thallium like other metals occurs naturally in water but some areas

Wireshark Capture The first step that needed to be taken in order to start this project was the download of the program Wireshark. In order to download Wireshark all I had to do was access the Wireshark website which was located at http://www.wireshark.org/download.html. Once that the program was loaded I was able to run a session and capture network traffic. When you first run a capture you have to choose which interface you are using. For this situation‚ I am running off of a wireless access card

Abundance and Extraction of Metals 1. a Mineral - A mineral is a naturally occurring inorganic solid‚ with a definite chemical composition‚ and an ordered atomic arrangement. b Ore - Deposit in the Earth of valuable metals contained in minerals. c Economic Natural Resource Deposit - This is a natural deposit of something that is economically viable to mine‚ refine and sell. Hence the deposit must be big enough to last for a large period of time‚ so that it will make enough money for the

The “Cumber-Coil”: A Revolutionary Product for the Value-Conscious SITUATION ANALYSIS Cumberland Metals Industries developed a new type of cushion pad for pile drivers made of curled metal. The 11.5 inch “Cumber-Coil” was tested by two different companies on two different projects and was found to far exceed the performance of the existing market-dominant product‚ the asbestos pad. The Cumber-Coil weighed half what the asbestos pad did and boasted a 33% faster driving time‚ 60% reduction in

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 the effects incurred on hardness values‚ width‚ length and thicknesses. Hardness values/vickers numbers are determined
