Abstract Due to the increasing demand for energy worldwide, photovoltaic (PV) cooling systems have become an important field of research in recent years. The most factor affecting performance a solar PV cell is its operating temperature. For harvesting heat from systems, phase change material (PCM) regarded as effective material. As result, this study discusses and describes effect using PCM na...

Climate change is one of the biggest environmental, political, economic, technological, and social challenges 21st century. Due to ever-increasing fossil fuels costs. The world energy system should be transitioned renewable sources mitigate greenhouse gas emissions. Solar suitable alternatives fuel usage. Currently, most widely available solar technologies are photovoltaic (PV) thermal. integra...

Cortical interneurons are classified into several subtypes that contribute to cortical oscillatory activity. Parvalbumin (PV)-expressing cells, a type of inhibitory interneuron, are involved in the gamma oscillations of local field potentials (LFPs). Under ketamine-xylazine anesthesia or sleep, mammalian cortical circuits exhibit slow oscillations in which the active-up state and silent-down st...

With the energy crisis and constant blackout in Mozambique Power Company grid, option of applying solar photovoltaic (PV) systems has been one most used alternatives neighborhoods Maputo region. However, inefficient power delivery caused by unproper sizing installation stand-alone PV contributing to low utilization potential The optimal system is addressed evaluate influence operation parameter...

Cholescystokinin (CCK)- or parvalbumin (PV)-containing interneurons are the major perisomatic-targeting interneurons in the cerebral cortex, including hippocampus, and are thought to form mutually exclusive networks. We used several techniques to test the alternative hypothesis that CCK and PV cells are coupled by chemical synapses. Triple immunofluorescence confocal microscopy revealed numerou...

Silicon based photovoltaic modules (PV) are a wide spread technology and used for small large PV power stations. At the moment, most efficient method which can be to improve annual electrical energy production of PVs is solar tracking systems. However, systems increase substantially initial cost investment insert maintenance costs. During last few decades, alternative improving methods have bee...

Parvalbumin (PV) is a cytosolic Ca2+-binding protein acting as a slow-onset Ca2+ buffer modulating the shape of Ca2+ transients in fast-twitch muscles and a subpopulation of neurons. PV is also expressed in non-excitable cells including distal convoluted tubule (DCT) cells of the kidney, where it might act as an intracellular Ca2+ shuttle facilitating transcellular Ca2+ resorption. In excitable...

The efficiency of PV (photovoltaic) modules is highly dependent on the operating temperature. objective this work to enhance performance by passive cooling using aluminum fins that have been nanocoated (like those an automobile radiator). A rise in cell temperature module leads a decrease its performance. As result, effective mechanism required. In work, has improved natural convection, which w...

Stable supplies of water, energy, and food are the most essential factors to universal achievements United Nation’s Sustainable Developments Goals (SDGs) by 2030. This work reports a self-sustained solar-driven, integrated water-electricity-crop co-production system (WEC2P). The design WEC2P is based on atmospheric water adsorption-desorption cycle (1) generate cooling power for photovoltaic (P...
