Answer the questions - Assignment Example When a huge asteroid will slam on the surface of earth, it will have the equivalent of a thousand nuclear bombs exploding simultaneously killing everything. Then the class help made me understand that the catastrophe will not just end there but in fact will have some geological and weather changes. The explosion will create a plume that will be sent into the atmosphere creating an unbearable winter or ice age that no human being or any living things could survive. It is just geologically impossible to drill through the steel hard rock of the asteroid. In addition to that, it is also physically impossible to work through the conditions of a flying asteroid with very little gravity. The article and the video summarizes the basic principles of how a nuclear reactor works. Nuclear energy is produced through thermal fission in power plants called thermal reactors. The fission is produced when thermal neutrons â€Å"move in thermal equilibrium with the environment they are in" At a temperature of 550F which corresponds to a velocity of about 3700 meters per second†. These neutrons strike a uranium-235 nucleus causing the nucleus to split into 2 unequally sized nuclei called fission fragments that contributes to the heating in the fuel. In sum, uranium rods are inserted or dipped into the water either to make boil to create energy such as in the case of boiling water reactors or to pressurized the heated water such as in the case of pressurized water reactors. There are two common kinds of nuclear reactor that produces energy. First is the boiling water reactors and pressurized water reactors. Boiling water reactors produce energy by boiling water where the steam is used to turn the turbines which creates the energy to become electricity. Pressurized Water  Reactors (also known as PWRs) on the other hand works differently from boiling water reactors as it instead keep the water in pressure so

Global project management - Essay Example The research has been conducted in order to identify and analyse the culture influenced problem in international project management.

According to Goffee and Jones (1996), cultural diversity brings verities of skills and expertise within project teams and can have a strong impact on the effectiveness of international project management. The diversity of culture and institutional difference between organizational members add extra cost in the large construction and engineering projects (Salomon and Schork, 2003). In the era of globalization, most of the companies are trying to manifests itself in international projects and offshore service delivery. Loosemore and Lee (2002) opined that globalization is the central theme of the today’s business society. However, it has been noticed that, project managers faces additional challenges to manage their project globally due to presence of cultural diversity. Religious beliefs and cultural factors impose external issues in the workplace. Cultural difference hampers the sense of belongingness and reduces cultural identity of the workers. Thus, one of the primary issu es to manage projects globally is the potential inability to communicate with the team members belonging from different cultural background. The literature section of the proposal deals with addressing the previous areas of research, theories, models and concepts in relation to the current topic. Through the study of existing literature, the researcher intended to identify the existing gaps in literature and based on that has tried to carry out a critical evaluation. Globalization has affected the approaches to project management and changed the needs
