The Effects of Leakage Radiation from X-Rays - Coursework Example The paper reveals the contribution of Heinrich Hertz to the history of radioactivity through the discovery of the presence of radio waves. However, it was Henri Becquerel, who conducted further studies on the beneficial effects of radioactive waves. The paper reveals that the work of the two scientists led to the discovery of the possible uses of radioactivity. Madame Curie is credited for having carried out researches that led to the discovery of more uses of radioactivity. The paper also reveals the contribution of Thomas A. Edison about the use of the most effective calcium tungstate-based option in the radiation process. Hal Gray is credited for having discovered the health-related use of radioactive waves while Herman Muller was the scientist who is credited for the discovery of the fact that radiation directly contributed to the production of new genetic traits.Radiation refers to the process through which energy is emitted in the form of waves or particles. Radiation pioneers played a very important role in radiation history effects. Scientists started making the first discoveries about radiation and atomic structures in the 19th century. A scientist by the name Wilhelm Conrad Roentgen is credited for the discovery of the basic properties of X-rays. Henri Becquerel was the one who first discovers radioactivity. All these discoveries and studies had a significant effect on the history of radioactivity. From the ideas that the pioneers discovered, other scientists are able to discover more about the use of radioactivity. In comparing the understanding of the concept of radioactivity during the 19th century, and the understanding of the same currently, it is evident that there is a significant improvement in the understanding and application of radioactivity in various fields.

Operation management - Essay Example Slack and Lewis (2008) identified three basic verticals for companies such as finance, marketing and operations while finance and marketing activities have close linkage to operation management Slack & Lewis (2008, p. 4) defined operation management as â€Å"it is the management of systems or processes that create goods and/or provide services.† Consideration of research works of Slack, Chambers & Johnston (2007) and Hsu & Tang (2010) reveals the fact that operation management has close linkage with supply chain activities. Slack, Chambers & Johnston (2007) defined supply chain management as the sequence of activities in order to supply resources throughout every phases of value chain. As part of synchronization of supply chain activities and operation management activities; facilities, functions and activities are being used. Facilities- warehouses, processing centres, offices, factories, distribution centres and retail outlets are the place where operations are took place (S lack, 2004). Functions and activities- operation management is collective act and not only operation manager but also supply chain partners and workers play vital role in performing activities like delivery of the resources or final output to facilities, inventory management, customer service, scheduling of operational activities, information management, forecasting of future demand, purchasing of material, designing new product, quality assurance testing etc (Slack, 2004). While describing nature of operation management in context to manufacturing sector, Slack (2004) and Slack & Lewis (2008) used the following model. Figure 1: Operation Model (Source: Slack & Lewis, 2008) According to the above model, operation management is backed by three strategic verticals such as resources, capabilities of the firm and process that will be deployed in manufacturing new product or processing a service. As part of resources; equipments, financial capital, staff, sourcing from suppliers and tech nologies is being used in operation management. As part of capabilities of the firm; application of state of art technology, quantitative formulation of process and process diagrams are being used by operation managers and respective staff members. As part of process; job design, movement of goods in the facilities, process design, new product concept design, new product development etc are being used as part of operation management. So, what is the role or types of activities that operations managers are involved in operation management? Answering the question is not simple because types of activities of operation manager differ significantly with the change in nature of business for organizations. For example, operational activities of operations managers in manufacturing plan cannot be same operational activities in bank. However, some basic activities of operations manager for manufacturing facilities can be identified as, 1- managing the resources that are being used in differe nt phases of manufacturing, 2- developing and adjusting production schedule, 3- monitoring and controlling quality in
