Abstract As the modern power system is advancing, new challenges are coming in to picture. The micro-grid concept along with renewable energy PV systems is emerging as a key factor for the long-term doable solution for future energy sector requirements. Micro-grid can have distributed energy resources like PV panels, wind turbines, Geothermal Tidal energy & power generators that produce power. Controlling and protection are the main problems that need to be handled in microgrid operation. Microgrids need to provide multiple end user needs simultaneously. For example, electricity generation, heating and cooling. This paper accords with the analysis of a Microgrid system connected with a PhotoVoltaic array.

Available Resources

Remote areas, where renewable energy systems can make their greatest impact, for the most part will not have data on the available resources. This is especially true in developing countries. Often, the designer has to estimate the resources either based on data available at similar or nearby locations or rely on qualitative information, which may be of the form :highly windy, highly variable, calm, mostly cloudy, etc. But, such information is only a snapshot and does not represent long term averages that are needed for planning. In present paper Micro Grid is planned for Makhla village in Amravati district as a rural electrification.

This article aims to explain why Japan has been at the periphery of the international humanitarian system, at least for the past two decades. Based on a review of the main features of the country’s historical involvement in humanitarian crisis response, I suggest two main reasons: 1) the difficulty for Japan to adapt to the kind of institutions created after the end of the Cold War, mainly by Western actors, and 2) Japan’s preference for an integral approach to crisis management, using multiple international cooperation means, which falls outside of the present humanitarian diplomacy paradigm. As this paradigm comes into question, Japan can influence the emerging humanitarian system, particularly through the promotion of crisis management ownership and long-term commitment backed by multiple financial means.

Grid Operation

The extent to which current is minimized helps in ensuring that the island to grid-connected mode transition is effectively controlled. This applies not only in the short-term but also in the long-term. This is also useful because it helps in maintaining the required level of flexibility as far as the framework of controlling island to grid-connected mode transition is concerned. The integration of interconnectors can also be useful with regard to control of island to gridconnected mode transition. This is because interconnectors can help in identification of shortcomings and existing gaps as far as the framework of island to grid-connected mode transition is concerned. A major reason why the use of interconnectors can help in controlling the island to grid-connected mode transition is that they facilitate continuous monitoring of the grid. This implies that the relevant changes can be identified and incorporated into the island to grid-connected mode transition, in this paper also comparative between two type of the algorithm control MPPT based on the fixed irradiance and temperature.

Abstract Issue Brazil is facing one the main growing public health concerns of this century, with obesity and overweight affecting approximately 20% of children. Alongside this epidemic, there is a an increase in concomitant non-communicable diseases such as diabetes and cardiovascular disease. Interventions that promote health and integrate the civil society with the public and private sectors are essential to tackle changes in the long term. Description of the Problem The nutrition education project presented here was developed by a Brazilian non-profit from 2016 to 2018. With a focus on health and nutrition, the project included interventions such as BMI monitoring, assessment of iron-deficiency anemia among children, school gardens and education. This strategy has been developed in several areas of the country, with success in all scenarios, demonstrating that a bottom-up approach, with the involvement of the community is needed to promote change. Results The program has been successful in integrating the major activities into the daily curriculum of the schools, with the adoption of healthier lunches for children. 76% of parents attested that a school garden made their children eat more fruits and vegetables and 33% of the children affirmed changing their eating habits after the program. Buy in from the local governments and communities demonstrate the effectiveness of interventions. Lessons Investments from the private sector on social programs needs to ensure a more sustainable approach, so that behaviour change, which is key to reduce the risk factors associated with NCDs can be fostered. This needs to be done with an integral approach, with the support from local, as well as national and international stakeholders. Key messages Long-term change is possible with a grassroots approach that engages communities towards a healthier lifestyle. A school or a home garden can bring about better nutritional choices.

AbstractNeurobiology-based interventions for mental diseases and searches for useful biomarkers of treatment response have largely failed. Clinical trials should assess interventions related to environmental and social stressors, with long-term follow-up; social rather than biological endpoints; personalized outcomes; and suitable cluster, adaptive, and n-of-1 designs. Labor, education, financial, and other social/political decisions should be evaluated for their impacts on mental disease.
