DHVSU Electrical Engineering Department Goes Green: Feasibility of Solar-Powered Building Using an Off-Grid Hybrid Solar Inverter

This research project unfolds the practicability of utilizing an Off-Grid Hybrid Solar Inverter to power up the Electrical Engineering Building in Don Honorio Ventura State University. To satisfy the aims of this research, a Solar PV System design was used to make use of the solar energy converting it to electrical energy to supply the whole building. This study was guided by doing a load schedule of all the appliances in the whole building to acquire the total power and total energy consumption, using it as a basis for the selection of the required electrical components and computation of the roof area to select a suitable solar panel in order to ensure the functionality of the whole Solar PV System. The raw data gathered was analyzed using formulas to acquire the needed electrical values. The findings resulted in the development and completion of the Solar PV System Design. The last part of the research is the results, discussions, conclusions, and recommendations. These provided the finalization and endorsement of the whole study

Obesity and physical activity in children of immigrants.

Childhood overweight and obesity have increased in recent decades, reaching alarming proportions. Children with a migrant background seem to be particularly at risk of developing overweight and obesity. This article provides an overview of the prevalence of overweight or obesity among North African (NA) children living in their own countries or as immigrants in Europe. The aim is to show the effect of the migration process on this trend and to discuss its possible contributing factors. Publications were identified by a systematic search of PubMed and the existing literature. Original longitudinal or cross-sectional studies on the prevalence of childhood and adolescent overweight and obesity and of physical activity among ethnic groups from North Africa compared with the native population were reviewed. The results confirmed that children of NA origin in Europe have higher levels of overweight and obesity than the native ones, especially girls. However, this trend can also be detected in urban areas of NA countries. Important factors contributing to the increase of overweight and obesity among children and adolescents are discussed, in particular the westernization of eating habits, the level of physical activity and body image perception. The review shows that factors linked to acculturation in the host society and others maintained from the country of origin come into play in determining childhood overweight and obesity among NA immigrants in Europe. The importance of health promotion targeting the groups most at risk of childhood overweight and obesity, i.e. aspects of a healthy diet and the benefits of physical activity, is underlined
