Renewable Energy Microgrid Design for Shared Loads

Renewable energy resource (RER) energy systems are becoming more cost-effective and this work investigates the effect of shared load on the optimal sizing of a renewable energy resource (RER) microgrid. The RER system consists of solar panels, wind turbines, battery storage, and a backup diesel generator, and it is isolated from conventional grid power. The building contains a restaurant and 12 residential apartments. Historical meter readings and restaurant modeling represent the apartments and restaurant, respectively. Weather data determines hourly RER power, and a dispatching algorithm predicts power flows between system elements. A genetic algorithm approach minimizes total annual cost over the number of PV and turbines, battery capacity, and generator size, with a constraint on the renewable penetration. Results indicate that load-mixing serves to reduce cost, and the reduction is largest if the diesel backup is removed from the system. This cost is optimized with a combination of particle swarm optimization with genetic-algorithm approach minimizes total annual cost over the number of solar panels and micro-turbines, battery capacity, and diesel generator size, with a constraint on the renewable penetration. Results indicate that load-mixing serves to reduce cost, and the reduction is largest if the diesel backup is removed from the system.

Use of Some Bacteria and Mycorrhizae as Biofertilizers in Vegetable Growing and Beneficial Effects in Salinity and Drought Stress Conditions

Industrialization and rapid population growth, especially after the second half of the twentieth century, have also revealed significant environmental problems in the world. The consistent and alarming increase in the human population has again threatened the world’s food security. It is becoming increasingly clear that conventional agricultural practices cannot sustain the production base, a healthy plant-soil system, for too long. There is a growing worldwide demand for compatible environmentally friendly techniques in agriculture, capable of providing adequate nourishment for the increasing human population and of improving the quality and quantity of certain agricultural products. For these reasons, the application of beneficial microorganisms is an important alternative to some of the traditional agricultural techniques which very often severely alter the agroecosystem balance and cause serious damage to health. Beneficial microorganisms can play a key role in this major challenge, as they fulfill important ecosystem functions for plants and soil. Utilization of these microorganisms affects plant’s growth and yield in a positive way. Besides, their favorable effects on root growth help plants to deal with both biotic and abiotic stress factors. PGPR and mycorrhizae can influence higher plants response to abiotic stresses such as drought and salinity through different mechanisms.

Focus on Coronary Atherosclerosis

Atherosclerosis is a vascular disorder consisting of thickening of arteries and lack of elasticity. Result of atherosclerosis is that arteries become narrowed and hardened due to an excessive buildup of plaque around the artery wall. The disease disrupts the flow of blood around the body, posing serious cardiovascular complications. Arteries contain what is called an endothelium, a thin layer of cells that keeps the artery smooth and allows blood to flow easily. Endothelial damage starts the first step of atherosclerosis. After this, lowdensity lipoprotein (LDL) cholesterol accumulates in the artery wall. Inflammatory process starts after this accumulation, and macrophages reach the endothelium to clean up cholesterol. But some macrophages are stuck in the affected part of the artery wall in this process. Over time, this results in plaque being built up, consisting of cholesterol and macrophage white blood cells. The plaque clogs up the artery, disrupting the flow of blood. This potentially causes blood clots that can result in life-threatening conditions such as heart attack and other cardiovascular diseases. Atherosclerosis can be seen in all arteries in the body. Atherosclerosis is the most common cause of death in the western countries. Some risk factors are as follows: age, sex, familial predisposition, hyperlipidemia, hypertension, diabetes mellitus, smoking, obesity, insufficient physical activity, etc. Whatever the main reason or the risk factor is, once atherosclerosis is formed, several life-threatening cardiovascular disorders can be seen. So, it has to be revealed.

Sub-2 μm Silica Particles in Chiral Separation

For decades, the race for the shortest chromatogram with the best resolution and separation efficiency has been the focus of researchers and manufacturers. Considerable advancement has been attained in the field of separation science with the widespread applications and outstanding performance of nanomaterials. According to the van Deemter equation, sub-2 micron particles employed in a conventional HPLC short column should subsequently result in analysis time reduction and efficiency improvements without the drawbacks of high pressure associated with sub-2 micron particles. This chapter provides comprehensive discussion about the applications of the new sub 2 microns silica particles in chiral separation of racemates.

Social Media: A Turning Point into Global Journalism Identity and Ethics

Social media are growing drastically representing a further step in the ongoing deterioration of journalism profession and ethics. The lines between professional journalists and amateurs have been blurred; consequently, the structure of news media has substantially changed affecting the core traits of the profession and its ethics. This phenomenon has challenged the already disputed concepts of journalism as profession and journalists as professionals. While this challenge is tremendous, research on its implications to journalism identity and ethics is scant. The existing literature focuses on new or digital media usage, newsgathering, production, dissemination, and consumption, with little emphasis on journalism ethics or the profession itself. This chapter seeks to examine how social media contribute to the ethical dilemmas off and online journalism encounter and how this transformation puts the profession at risk.

Traits of leadership for efficacious communication of Project Management in Software Industry of Pakistan

From 1930 to 1940 personality and appearance were considered better for a leader. In 1940 behavioral school of thoughts focused on leadership tasks and emphasized on learning leadership instead of an inborn trait. Different leadership ways for different leadership situations; by applying the skills owns by a Project Manager to the leadership situations; suggested by contingency school of thoughts in 1960‟s. Organizational change by vision, charisma, respect, and trust was proposed by the Visionary and Charismatic School of thought in 1980‟. Muller and Turner in 2010 presented the emotional intelligence seminary. For the job triumph, the Individual potential of self-cognizance, self-organization, civic wakefulness and masses affiliation administration can be applied. Goleman, D. (2000). Emotional Intelligence is skilled those must be educated and this can result in an outstanding performance at work Goleman, D. (1998).
