An efficient cooling system for data centers can boost the working efficiency of servers and promote energy savings. In this study, a laboratory experiment computational fluid dynamics (CFD) simulation were performed to explore performance two-phase system. The coefficient (COP) partial power usage effectiveness (pPUE) proposed was evaluated under various IT (Information Technology) loads. rela...

Pre-cooling is an important step in the post-harvest management of fresh produces. This study was initiated to evaluate effect hydro and cold room pre-cooling on cooling kinetics quality parameters for amla. Amla fruits were cooled using immersion method chlorinated water (200 ppm) at 3, 5, 8℃ temperatures, while Cold Room (CR) done a display-type refrigerator 6℃. Comparative showed highest rat...

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...

As the heat flux of electronic components is increasing rapidly, traditional air-cooling technique gradually not meeting requirements thermal management. The immersion liquid-cooling shows great potential, and has attracted attention due to its excellent performance in recent years. finned sink common essential for cooling electric components. To analyze influences structural parameters on diss...

Eleven women (age = 24.4 +/- 6.3 yr, mass = 65.0 +/- 7.8 kg, height = 167 +/- 8 cm, body fatness = 22.4 +/- 5.9%, mean +/- SD) were immersed to neck level in 18 degrees C water for up to 90 min for comparison of their thermal responses with those of men (n = 14) in a previous similarly conducted protocol. Metabolic rate increased about three times resting levels in men and women, whereas the ra...

Sleep Apnea Syndrome (SAS) is a sleep related-breathing disorder with several features such as systemic inflammation, oxidative stress, cognitive impairment and poor quality. Patients SAS have an increased risk of cardiovascular diseases. There no real effective treatment that prevents treats all these illness symptoms. Cooling therapies are often used in sport medicine athletes after training ...

This study examined the effects of thought suppression, prior to an experimental pain procedure, on subsequent pain experience. The study also examined the role of thought intrusions in mediating the relation between (1) thought suppression and pain, and (2) catastrophizing and pain. Catastrophizers (n = 34) and noncatastrophizers (n = 36) made pain ratings while one arm was immersed in ice wat...

The purpose of this study was to investigate the effect of an uneven surface on muscle spindle function in lower-leg muscles during walking. Subjects included 3 healthy young adult males. Normal and high-speed walking motion ware measured on two surfaces: an even surface and an uneven surface. Healthy and reduced muscle spindle function conditions were compared. The ice immersion approach was a...
