Why Franchise. Franchising has attracted some 34‚000 people in the UK to invest in their future in self employment. Here are 15 reasons why franchises offer an attractive business opportunity. 1. Established brand value. Prior to launching a franchise‚ the franchisor has developed and established attractive and meaningful branding for the operation‚ and as the network of franchisees expands the national recognition of this brand grows. When a franchisee enters into a mature franchisee network

Short Paper: Mantle Convection‚ The Forces Behind Plate Motion PHSC 210-Spring B Term‚ Elements of Earth Science February ‚ 2014 Short Paper: Mantle Convection‚ The Forces Behind Plate Motion Introduction The paper is about plate mantle convection‚ the forces behind plate motion. Lutgens & Tarbuck (2014) found “Convection is a type of heat transfer that involves the actual movement of a substance” (p. 177). Plate mantle convection is described by Merriam-Webster’s

Research on Conduction‚ Convention‚ and Radiation Conduction is the exchange of warmth between substances that are in direct contact with one another. The better the conductor‚ the all the more quickly warmth will be exchanged. Metal is a decent conduction of warmth. Conduction happens when a substance is warmed‚ particles will acquire vitality‚ and vibrate more. These atoms then chance upon adjacent particles and exchange some of their vitality to them. This then proceeds with and passes the vitality

free convection and to determine the heat transfer coefficients for several rods. These objectives were met by heating several rods and allowing them to cool through free convection in air‚ free convection in water and forced convection in water- while monitoring their change in temperature over change in time. Seven heat transfer coefficients were determined during the laboratory for various rods. A copper rod underwent free convection in air‚ free convection in water and forced convection in water

India is the leading milk producing country in the world with a production of about 110 million ton per annum. The leaders of milk procurement in India‚ Anand Co-operative society followed by Nestle often face a scarcity of milk supply to meet their national and global demands particularly in summers. The major reasons for the less supply during the summers were analyzed and the study coined a term known as “Heat Stress”. Heat Stress is correlated to both ambient temperature and humidity level

ABSTRACT In this experiment‚we use a microwave dryer to dry the wet sand . We choose to use a mixture of sand and water because we believe that sand is a solid which possesess both regular and irregular crystal lattice structure ‚ therefore making the movement of water particle easy and decrease faster ‚leading to a short drying time. The measurement of the moisture content is based on the weight sample which is inversely proportional with the temperature and time ‚ though the temperatue is kept

Development Of A Manufactured Product Dried Fruits- Apricots Presented To Mrs Lawrence and Mrs Mann Presented By Sophie Xian Year 12 food technology Introduction Drying is one of the most ancient methods of preserving foods; this method is still very popular and is used for drying fruits‚ beef (jerky)‚ fish‚ evaporated milk and much more. This method removes the moisture content of food to restrict microbial activity. The main methods of drying include sun drying‚ spray
