Crystalline silicon photovoltaics are a cardinal and well-consolidated technology for the achievement of energy efficiency goals, being installed worldwide production clean electrical energy. However, their performance is strongly penalized by thermal drift, mostly in periods high solar radiation where cells reach considerably temperatures. To limit this aspect, employment cooling systems appea...

Radiative cooling, a unique and uncommon passive cooling method for devices operating outdoors, has recently been demonstrated to be effective for photovoltaic thermal management. In this work, we investigate the effect of radiative cooling as a complement to existing passive cooling methods like convective cooling in a related system with much higher heat loads: a high-concentration photovolta...

During the digestive-tract phase of infection, poliovirus (PV) is found in the oropharynx and the intestine. It has been proposed that PV enters the organism by crossing M cells, which are scattered in the epithelial sheet covering lymphoid follicles of Peyer's patches. However, PV translocation through M cells has never been demonstrated. A model of M-like cells has been previously developed u...

Hybrid photovoltaic-thermal heat pump (PV/T-HP) solar energy systems are promising since they can achieve a system total efficiency greater than 80%. By maximizing the output of PV/T for simultaneous heating and cooling, this strategy meet over 60% urban households’ needs around 40% their cooling needs. In work, novel evaporator was designed, fabricated, an aluminium foil encapsulated hydrated ...

Plasmalemma vesicle protein-1 (PV-1) is a caveolae-associated protein that is enriched in lung endothelial cells. The PV-1 protein is first detected in the lung at embryonic day 12, before that of caveolin-1 (Cav-1). There is a postnatal rise in PV-1 and Cav-1 mRNA levels, reaching a peak at the time of weaning and declining to their lowest levels in the adult lung. In contrast, the PV-1 protei...

AIM To evaluate the synergistic targeting and killing of human hepatocellular carcinoma (HCC) cells lacking p53 by the oncolytic autonomous parvovirus (PV) H-1 and chemotherapeutic agents and its dependence on functional promyelocytic leukemia protein (PML). METHODS The role of p53 and PML in regulating cytotoxicity and gene transfer mediated by wild-type (wt) PV H-1 were explored in two pair...

Neocortical pyramidal cells (PYRs) receive synaptic inputs from many types of GABAergic interneurons. Connections between parvalbumin (PV)-positive, fast-spiking interneurons ("PV cells") and PYRs are characterized by perisomatic synapses and high-amplitude, short-latency IPSCs. Here, we present novel methods to study the functional influence of PV cells on layer 5 PYRs using optogenetics combi...

Cells isolated from human first trimester umbilical cord perivascular layer (hFTM-PV) tissues display the pluripotent characteristics of stem cells. In this study, we examined whether hFTM-PV cells can differentiate into islet-like clusters (ILCs) in vitro, and whether transplantation of the hFTM-PV cells with and without differentiation in vitro can alleviate diabetes in nude mice. The hFTM-PV...

BACKGROUND The differences in ablation characteristics of freezing time and balloon size using second generation cryoballoon are still unknown. METHODS AND RESULTS Twenty-six dogs underwent pulmonary vein (PV) isolation. Balloon and tissue temperatures (left atrial-PV junction, phrenic nerve, and internal esophagus) were monitored. The ablation duration was randomized to either 3 or 4 minutes...

One of the critical emerging branches solar technology is photovoltaic/thermal (PV/T) systems that amalgamate collectors and photovoltaic panels into a unit to produce heat electricity from stochastic insolation. In sunny countries, conversion efficiency ( $\eta$...
