The solar radiation absorbed by the photovoltaic thermal systems and not transformed into electricity creates a problem that significantly influences reliability efficiency of cells. In order to passively solve this in hot arid climate, night radiative cooling technology was proposed work, where water system cooled circulating collector exploiting technique, it used next day for For aim, mathem...

Solar energy is highly appreciated among different renewable sources due to its limitless potential and affordable conversion technologies. Conventionally, solar has multiple thermal applications, but now with the onset of photovoltaics (PV), there massive momentum for electricity generation. However, PV module faces a major challenge efficiency decrement an increased working temperature. Hence...

Plasmalemma vesicle protein-1 (PV-1) is an integral membrane protein associated with endothelial cell caveolae and fenestrae. Since endocrine glands are enriched with fenestrated endothelium, we examined the distribution of PV-1 mRNA and protein in endocrine glands and determined its cellular localization. A single transcript was detected by RT-PCR in all endocrine glands examined. A synthetic ...

The inability of papillomaviruses (PV) to replicate in tissue culture cells has hampered the study of the PV life cycle. We investigated virus-cell interactions by the following two methods: (i) using purified bovine PV virions or human PV type 11 (HPV type 11) virus-like particles (VLP) to test the binding to eukaryotic cells and (ii) using different VLP-reporter plasmid complexes of HPV6b, HP...

The present study evaluates the environmental profile of a PV-green roof (PV panels over a soil/plant layer) and other roofing systems (PV-bitumen, PV-gravel, gravel, extensive green and intensive green). The analysis is based on multiple life-cycle impact assessment methodologies (ReCiPe, etc), several scenarios (for example with and without recycling) and it provides a deeper analysis as well...

The cerebellar cortex has a fundamental parasagittal organization that is reflected in the physiological responses of Purkinje cells, afferent and efferent connections, and the expression of several molecular markers. The most thoroughly studied of these molecular markers is zebrin II (ZII; a.k.a. aldolase C). ZII is differentially expressed in Purkinje cells, resulting in a pattern of sagittal...

Overheating in BIPV/T applications is a concern due to its negative impacts on the electrical conversion efficiency of solar cells. Forced air cooling can be an effective thermal management strategy. However, effectiveness limited by resistance associated with boundary layer formation walls channel. The heat transfer improved appending transverse ribs This study numerically investigates energy ...

Photovoltaic (PV) modules and solar thermal collectors are convectional solar systems that convert solar radiation into electricity and heat energy respectively. PV modules generate clean electricity and ideal for use in developing countries where human settlement is scattered in remote rural areas and no grid electricity is available. However, electrical conversion efficiency of commercial PV ...

Abstract In the current energy context, solar is cheapest source of renewable energy. Photovoltaic cells (PV) and air thermal collectors (ATC) are used to convert irradiation into electricity heat. this research a model for hybrid system consisting in photovoltaic panel behind which hot collector was designed tested. This produces both heat, from sun, based on principle two one. Romanian climat...
