Renal nerves and nNOS:roles in natriuresis of acute isovolumetric sodium loading in conscious rats [PDF]

, 2008
Udgivelsesdato: AprIt was hypothesized that renal sympathetic nerve activity (RSNA) and neuronal nitric oxide synthase (nNOS) are involved in the acute inhibition of renin secretion and the natriuresis following slow NaCl loading (NaLoad) and that RSNA ...

Thermodynamic screening of alternative refrigerants for R290 and R600a

Results in Engineering, 2020
Due to Regulation EU 517/2014 (F-Gas), the use of refrigerants with GWP higher than 150 was limited from 2015 on in small capacity refrigeration systems in Europe.

A simulation of R32 refrigerant mixing with R1270 to reduce GWP R410A on wall mounted air conditioning

IOP Conference Series: Materials Science and Engineering, 2021
Abstract Refrigerant R410A is a cooling barrier that is still widely used for air conditioning. This R410A contains the Fluoro element which can increase the value of GWP. In this research simulation, we used an AC unit using R410A with the aim of reducing GWP (Global Warming Potential) by mixing synthetic refrigerant with hydrocarbons ...

Experimental evaluation of alternative CO2-based blends for transcritical refrigeration systems [PDF]

, 2023
This work presents two refrigerant CO2 blends with R32 and R1270 designed with a theoretically nonflammability and a GWP below 150. Both mixtures were tested in a small-capacity vapour compression system with and without IHX, considering the same ...

Analysis of charged particle emission sources and coalescence in E/A = 61 MeV $^{36}$Ar + $^{27}$Al, $^{112}$Sn and $^{124}$Sn collisions

, 2004
Single-particle kinetic energy spectra and two-particle small angle correlations of protons ($p$), deuterons ($d$) and tritons ($t$) have been measured simultaneously in 61A MeV $^{36}$Ar + $^{27}$Al, $^{112}$Sn and $^{124}$Sn collisions. Characteristics

Refrigerator Performance With Natural Refrigerant (R1270) Double Pipe Heat Exchanger, Various Capillary Pipe Lengths

JST (Jurnal Sains dan Teknologi), 2023
Refrigerator technology continues to develop towards a better and more efficient direction. Refrigerator must be given a touch of innovation to get the best performance. This study aims to obtain data on the performance of refrigerators with double pipe heat exchanger innovation and variations in the length of the capillary tube.
