Economies of Scale * This is the cost advantage that a business obtains due to expansion. * That is the factor that cause the average cost of producing a product to fall‚ as output of the product rises as explained in the ‘Dictionary of Economics’. * By achieving economies of scale‚ a company would have the cost advantage over its existing and new rivals. * Further‚ the company could achieve lower long run average cost (i.e. productive efficiency). But if technology changes‚ this

The Large Hadron Collider The Large Hadron Collider is the largest‚ most powerful‚ and most expensive particle accelerator in the world. It cost 20 countries over $9 billion to build and finance the project. The Large Hadron Collider was built by CERN‚ the European Organization for Nuclear Research. CERN is composed of 20 member nations with the purpose of researching and conducting experiments on particle physics. The purpose of the Large Hadron Collider is to assist in answering fundamental

Diseconomies of scale A more precise definition is that long run average costs per unit rises with an increase in output.This can b shown in the diagram below: [pic] The rising part of the Long Run Average curve illustrates the effect of diseconomies of scale. Beyond Q1 (ideal firm size)‚ additional production will increase per unit costs. Diseconomies of scale are rarer than economies of scale and they are often offset by economies of scale that exist in the same business. This can make

The Braden scale can identify if an individual is at risk for developing pressure ulcers. The Braden scale has a numerical (6-23) rating system based on ones sensory perception‚ skin exposure to moisture‚ physical activity‚ mobility‚ nutrition‚ and risk for friction and shearing (Braden‚ Maklebust‚ & Maklebust‚ 2005). A lower Braden Scale Score is and indicator that an individual is at a greater of developing a pressure ulcer due to ones lowers level of functioning. Whereas a higher score indicates

Unlocking the Secrets of the Universe Increasing our knowledge of Physics‚ using the scientific method to make observations and test hypotheses is essential to unlocking the secrets of the universe. Energy is one of the most fundamental elements of the universe. Throughout history‚ man has endeavored to expose‚ understand‚ and explain how and why things work. This drive to expand our understanding eventually led to the development of the scientific method and what is commonly considered

SMALL SCALE INDUSTRY INTRODUCTION The definition for small-scale industrial undertakings has changed over time. Initially they were classified into two categories- those using power with less than 50 employees and those not using power with the employee strength being more than 50 but less than 100. However the capital resources invested on plant and machinery buildings have been the primary criteria to differentiate the small-scale industries from the large and medium scale industries. An
