This paper presents a review of recent photovoltaic cooling technologies and techniques used to reduce the negative impact increased temperature enhance production electricity by (PV) modules. Various methods are reviewed; namely, Thermoelectric cooling, PV with phase change materials (PCM) nanofluids, systems cooled forced water circulation, immersion technique, heat sinks, solar spraying. Sev...

Chronic ethanol feeding selectively impairs the translocation of cytosol GSH into the mitochondrial matrix. Since ethanol-induced liver cell injury is preferentially localized in the centrilobular area, we examined the hepatic acinar distribution of mitochondrial GSH transport in ethanol-fed rats. Enriched periportal (PP) and perivenous (PV) hepatocytes from pair- and ethanol-fed rats were prep...

Perisomatic inhibition of pyramidal neurons is established by fast-spiking, parvalbumin-expressing interneurons (PV cells). Failure to assemble adequate perisomatic inhibition is thought to underlie the aetiology of neurological dysfunction in seizures, autism spectrum disorders and schizophrenia. Here we show that in mouse visual cortex, strong perisomatic inhibition does not develop if PV cel...

Coxiella burnetii is an intracellular bacterial pathogen and a significant cause of culture-negative endocarditis in the United States. Upon infection, the nascent Coxiella phagosome fuses with the host endocytic pathway to form a large lysosome-like vacuole called the parasitophorous vacuole (PV). The PV membrane is rich in sterols, and drugs perturbing host cell cholesterol homeostasis inhibi...

GABAergic inhibition has been shown to play an important role in the opening of critical periods of brain plasticity. We recently have shown that transplantation of GABAergic precursors from the embryonic medial ganglionic eminence (MGE), the source of neocortical parvalbumin- (PV(+)) and somatostatin-expressing (SST(+)) interneurons, can induce a new period of ocular dominance plasticity (ODP)...

OBJECTIVE Poliovirus (PV) enters the host by the oral route and can infect the central nervous system (CNS) by two mechanisms: crossing the blood-brain barrier and traveling along the nerves from the muscle to the spinal cord. In the latter mechanism, the PV receptor, CD155, and the motor protein, dynein, have been implicated in the transport of PV to the CNS. In this work we analyzed the possi...

Pemphigus vulgaris is an autoimmune blistering disease characterized by a loss of epidermal cell-cell adhesion caused by anti-desmoglein (Dsg) autoantibodies. The pathogenesis of PV remains unclear. However, abnormal frequency and function of Th2 cells are believed to contribute to PV. We investigated Nr4a2, a transcription factor, which has been found to regulate T cell differentiation, for it...

Compared to traditional one-sun solar cells, multijunction concentrator cells operating under concentrated radiation are advantageous because of their high output and low cooling costs. Such a PV requires technique maintain its performance efficiency. The multi-junction photovoltaic cell efficiency around 33%, (160–250 sun), has been tested. Heat pipes were used in this study as fast efficient ...

Solar energy has advantages such as accessibility, applicability and predictability compared to other renewable sources. This source is used for many purposes in the world. Photovoltaic panels provide applications generating electricity from solar or heating cooling. Their performance changes depending on PV panel material, amount of radiation operating temperature factors. In electrical conver...
