Question 1: Globalisation has‚ in the last few decades‚ been one of the dominant trends in retailing. Retailers around the globe are striving for higher global market shares. The food retailing industry which has an oligopolistic market‚ especially‚ has strong competition although‚ with a few large firms dominating the market. Among them Tesco and Lidl are one of the major European retailers. Tesco is the UK’s largest retailer with 28.7% market share‚ which is 11% more than its closest rival‚ ASDA

Therefore‚ the phenotypic ratio of F2 offspring is 9 horizontal stripes with triangle-hair shape to 3 horizontal stripes with rectangle-hair shape to 3 vertical stripes with triangle-hair shape to 1 vertical stripes with rectangle-hair shape. Provided that there are 40 F2 offspring‚ we expect that there are 9/16 x 40=22.5 horizontal stripes with triangle-hair shape to 3/16 x 40=7.5 horizontal stripes with rectangle-hair shape to 3/16 x 40=7.5 vertical stripes with triangle-hair

theodolite is an instrument which is capable of measuring angles to the nearest whole second [Figure 4.1]. This can be done for both vertical and horizontal angles. Vertical angles are required for the calculation of elevation of points for example the reduction of slope distance to the horizontal. Figure 4.1: Atheodolite Source: SouthGeosystems Horizontal angles are required to obtain the relative direction to a survey control station or points of detail. Basically there are two types of modern

PLASTIC COLLAPSE OF A PORTAL FRAME AIM The purpose of this experiment is to find out how a portal frame deflects when horizontal and vertical external loads are applied to it. This experiment will then help in the comparison between what is theoretically expected to happen to the portal frame and what is actually recorded to happen during the experiment. The portal frame in this experiment is part of a statically indeterminate structure. BACKGROUND INFORMATION For any material‚ there

*monitor History of Monitor A long time has passed since the first computer monitors were introduced. Way back when these units were first introduced‚ they were available in monochrome only and most of the computer monitors used to have a bright green display on a jet black background. These were known as monochrome monitors and they did not use to have high quality displays. The displays that we see on the monitors are caused by the electrons directed on a phosphor coating on the screen by the

wells.Fracking as a method for oil and gas extraction is also more economically viable than conventional or horizontal drilling. The last reason is that the process has driven down gas prices and offered gas security to both the United States and Canada for about 100 years. This is why we should keep fracking.
