Jet Streams Jet streams are strong westerly winds that blow in a narrow band in Earth ’s upper atmosphere at the same altitudes at which airplanes fly. They form because of temperature variations between the poles and equator. There are two occurrences that results in the Jet Streams. The first occurrence would be when hot air rises from the tropics towards the North and South Poles subsequently the second occurrence is as the hot air is moving to the north and south poles from the tropics‚ the

CU1521-Support children and young people’s health and safety Task 3 Assessment criteria 3.3- give examples from own practice of supporting children or young people to access and manage risks. Whilst I was at placement I have taken part in a lot of activities. Some of these have needed me to tell the children how to work safely. One of the activities that I had to do this was when they were using the scissors. I assisted in an activity where they had to make poppies. This was done by making

dams‚ levees – depend on the stability‚ strength‚ and deformation of soils.[1] Unfortunately‚ due to the uncertainties of the world’s natural materials‚ the study of geotechnical engineering‚ and soil mechanics in particular‚ is both challenging and necessary. The following report is a compilation of the results acquired as a result of two laboratories performed by Group 13 at McMaster University on February 1st and 15th‚ 2007.

Flying Wind Generators Flying wind generators are the future of wind energy. This article talks about the replacement of wind turbines for “windmills in the sky”. Instead of using the current wind turbines‚ Bryan Roberts‚ and engineer at University of technology in Sydney‚ Australia‚ decided to fly wind turbines into the jet stream 15‚000 to 45‚000 feet into the sky with winds up to 200 miles per hour. With 600 of these producing 20 megawatts each could power two Chicago sized cities. The

Background Automek a large multinational auto component manufacturer headquartered in North America with plants worldwide. It supplied complete systems to many car manufacturers globally. This particular project was the first time that it had supplied components to OEM. Automek was looking forward for more business form OEM if this was successful. Due to increasing cost in the United States‚ Automek was on a lookout for global low-cost source. During its search it came across Agile in India and

The purpose of this report was to optimize a sufficient load capacity and power loss of a journal bearing and determine the life expectancy of a ball bearing. This was to be done with only a given set of parameters and set of variables were to be chosen. The parameters of a given shaft with flywheel were shaft details: diameter = 90mm‚ total weight of shaft and flywheel = 25kN‚ RPM = 1500 and power of 3.5MW.

Ministry of Educational Zone Tornado INTRODUCTION The word tornado is an altered form of the Spanish word tronada‚ which means thunderstorm. This in turn was taken from the Latin tonare‚ meaning to thunder. It most likely reached its present form through a combination of the Spanish tronada and tornar. A tornado is also commonly referred to as a twister‚ and is also sometimes referred to by the old-fashioned colloquial term HYPERLINK http//en.wikipedia.org/wiki/Cyclone o Cyclone cyclone. HYPERLINK
