The paper presents a literature review regarding defrosting methods for household refrigeration and heat pumps. covers the period between 2008 2020. A number of 61 papers have been studied. was conducted by dividing defrost into passive active. Passive involve surface coating off-cycle. active reverse cycle, ultrasonic vibration, hot–gas defrost, electric heating hot fluid. Surface vibration ar...

The impact of body core heating on the interaction between the cutaneous and central circulation during blood pressure challenges was examined in eight adults. Subjects were exposed to -10 to -90 mmHg lower body negative pressure (LBNP) in thermoneutral conditions and -10 to -60 mmHg LBNP during heat stress. We measured forearm vascular conductance (FVC; ml. min(-1). 100 ml(-1). mmHg(-1)) by pl...

most of the researches do not differentiate between intuitive critic and passive one – in the field of features, applications and methods. this critical school is called emotional or passive critics which emphasizes aesthetics. thus sensitivity is not the only appliance to wisdom but is a mean to inspire happiness or unhappiness feeling. consequently the passive (critical) school is the result ...

The literature showed many studies that evaluated single or multiple Phase change materials (PCMs) layers in passive, active, hybrid configurations for building applications. However, little attention has been given to evaluating the energy performance of buildings when PCMs are used together with other passive design strategies. In this work, an office a typical arid Saharan climate is simulat...

The acute effects of passive whole-body hyperthermia on the integrity neurovascular unit (NVU) in humans have remained unclear. We demonstrate that heating for ∼1 h until an increase +2°C esophageal temperature healthy men does not cerebral release neuronal parenchymal stress biomarkers, suggesting NVU is maintained. This preliminary study indicates safe brain, at least young men.
