Super size me - Essay Example Over a 30-day period, Spurlock further stops any and all exercise routines to further reflect the impact of McDonalds foods on human physiology. Outside of the physical effects, the film illustrates how the media impacts consumers to reflect what Spurlock believes is an unacceptable method of coercing Americans to indulge in fast food. Throughout the course of the film, Spurlock examines several decades worth of television commercials released by McDonalds since the 1970s, in order to depict how the media is able to coerce both children and adults into eating at the fast food chain. These commercials depict playful animated characters, who dance and sing with the prospect of being taken to McDonalds to indulge in greasy food (Sowers, 2006). From a psychological perspective, Spurlock comes to realize that McDonalds is using visual imagery, in the pursuit of stimulating a pleasurable connection between the fast food company and its menu items. Further, in the film, the well-known character, Ronald McDonald, is shown as a leader to children, engaging in pleasurable activities such as community basketball and various sporting events. This tends to indicate, to a less-sophisticated person in terms of identifying media influences, that McDonalds is a community-minded organization and that implicit trust should be given to the chain because of their charming spokesperson. Outside of the visual imagery, Spurlock further points out non-print media attempts to build a stronger loyalty to McDonalds with the insertion of signs and banners, all over the United States (and released by McDonalds), which promote the need to super size meals. Supersizing involves increasing the food portions by a significant margin, thus increasing the fat and caloric value of the food. Though Spurlock is somewhat biased in his approach to the film, he maintains a

Condition Monitoring Photovoltaic Energy Systems-based reliability Research Paper

Condition Monitoring Photovoltaic Energy Systems-based reliability - Research Paper Example Major PV Modules and Types Solar energy is considered as a major basis of renewable and sustainable power which can be effectively generated through the utilisation of the PV method. The PV system consists of constructing blocks which are also termed as modules or cells that are connected together and is able to transform ‘sunlight into electricity’. According to Chow, PV system generates low Green House Gas (GHG) emission and is also recognised as a clean basis of energy. PV system is developed by assimilating variety of semiconductor materials so as to generate power with high capacity. There are four major types of PV modules which are ‘crystalline silicon’, ‘polycrystalline’, ‘amorphous silicon module’ and ‘thin-film module’. Every PV modules have diverse efficiencies owing to which the overall performance of these PV modules tend to rely on the ingredients as well as the operating situations based on various factor s such as temperature, intensity of solar radioactivity and the inclusive design of the system. Furthermore, the orientation and location of PV array also creates a significant impact on the electricity production capacity through the usage of solar energy depending on the weather conditions. The four major types of PV modules, i.e. crystalline silicon, polycrystalline, amorphous silicon and thin film (Chow, â€Å"Modeling Urban Solar Energy with High Spatiotemporal Resolution†). As stated by Mangersnes, Crystalline PV modules are frequently specified as being the most reliable component of the PV system. This presumable reliability is demonstrated through its large warranty periods. Crystalline Silicon PV is the most extensively used PV technology. It is developed through solar cells made by ‘crystalline silicon’. This type of cells is equipped with high level of affectivity and thus is also regarded as an interesting technology. In general, there are two kinds of solar cells which are ‘mono-crystalline silicon’ and ‘multi-crystalline silicon’. Mono-crystalline silicon is developed by cutting wafers from high clarity single crystal lump. Similarly, the multi-crystalline silicon is developed by cutting a cast tablet of silicon into blocks and wafers. In general, mono-crystalline silicon cells have much higher effectiveness in comparison to multi-crystalline silicon solar cells. The crystal type module usually applied for this technology is iron glass which is combined with anti-reflective layer, to make sure that the maximum solar radioactivity spreads to the crystalline solar cells and thus the energy generating capacity can be enhanced (Mangersnes, â€Å"Back-contacted Back-junction Silicon Solar Cells†). Polycrystalline PV modules include small silicon glass pieces. Polycrystalline is generally used for developing gate constituents in semiconductor devices. Polycrystalline modules are most commonly used f or generating electricity, as it is considered to be quite inexpensive in comparison with other PV modules. The reason for polycrystalline modules to be inexpensive is owing to its production procedure. In the production process of polycrystalline, the melted silicon is dispensed into a cast rather than into one single crystal. The components of polycrystallin
