Critical assesment of geochemistry and geophysics Essay

Critical assesment of geochemistry and geophysics - Essay Example It is mostly the remnants that have been buried by layers soil and rocks that have higher chances of being preserved. This is because the exposed cultural remnants may be displaced by anthropogenic or environmental factors (Blofeld J. 2004 p.71). The buried remains are usually covered with sediments accretion from water and wind erosion or natural processes such as earthquakes, mud flows and earth quakes. Some old structures may also be buried when new ones are built on top of them. The buried remains are effectively explored through geophysical and geochemical prospecting. These methods are efficient in detecting the invisible characteristics of the remains. The devices used in are significant in distinguishing between relics, which is significant in tracing human remains. The two techniques were developed in a bid to increase professionalism in archeology. The use of geophysics is an effective way of detecting deviations in the magnetic field of the earth through the use of magnetometers. These magnetic fields emanate from artifacts of iron metal as well as structures that were made of stone. Together with these techniques, devices that measure electrical resistance of the soil are also used (Bose R. N. 2005 pp.56-57). Geophysical and geochemical prospecting are two major techniques that have been widely employed. The two techniques are significant in the identification of human activities that exist as remains buried under the earth surface. The characteristics of the remains are analyzed by an expert who establishes whether they represent human activities or natural factors. The archeological site of Apamee was investigated with the use of the two techniques. They have enhanced the understanding of this archeological site. In the United Kingdom, the two techniques have been applied in many archeological surveys (Braithwaite, R. 2001 pp. 121-123). Fluxgate gradiometers are the most commonly used for surveying due to the fact that they are affordable for

The Economic Environment of Business questions Essay

The Economic Environment of Business questions - Essay Example In short, it can be concluded that Aldi’s share would increase substantially after opening of new stores in different areas across Britain. Â   Â  (Hawkes, 2008) The word downturn refers to a slump in sales due to economic recession and meltdown that because unemployment increases and consumption decreases. The business organisations observe negative growth in their businesses since customers are inclined to make purchases of necessities and are reluctant to make purchases of luxuries and other items with higher price elasticity. Supermarket Industry is an oligopolistic industry since there are few businesses (large scale producers and retailers) that dominate the market and reap benefits. These businesses may set industry total output and prices of their products. Moreover, they have mammoth financial resources because of revenue they generate from their several in-town and out-of-town supermarkets. They also attract a large pool of customers compared to what a small retail shop attracts. It is worthwhile to mention that retailers face stiff competition with their rivals so that each could attract maximum customers. Tesco is one of the leading retailers in UK’s supermarket industry that enjoys a market share of over 28%. Since, it has the potential of offering more than 40,000 products from its organised chain of retail outlets all across Britain; it enjoys monopoly like situation in many instances. Tesco offers various products that attract more buyers than any other retailers including Aldi and Sainsbury. It must not be forgotten that Tesco faces stiff competition from other retailers; therefore, it may not restrict or control production / supply of every product as well as set higher prices to reap abnormal profits. Instead, Tesco may take advantage from products that are not offered by any other retailer and therefore customers are dependent over it to make their purchases. (Hawkes, 2008) Like other
