The balance between metabolic heat production, heat removal by blood flow, and heat conductance defines local temperature distribution in a living tissue. Disproportional local increases in blood flow as compared with oxygen consumption during functional brain activity disturb this balance, leading to temperature changes. In this article we have developed a theoretical framework that allows ana...

Cryogen spray cooling (CSC) protects the epidermal layer during dermatologic laser surgery (DLS) of superficial vascular lesions. Because of spray characteristics the protection provided radially is relatively uniform only by the spray axis. The present work explores mass-deposition passive-control during CSC in order to increase the radial homogeneity of heat extraction. A stainless steel mesh...

In oncology, the term 'hyperthermia' refers to the treatment of malignant diseases by administering heat in various ways. Hyperthermia is usually applied as an adjunct to an already established treatment modality (especially radiotherapy and chemotherapy), where tumor temperatures in the range of 40-43 degrees C are aspired. In several clinical phase-III trials, an improvement of both local con...

BACKGROUND AND PURPOSE Warm-up prior to static stretching enhances muscle extensibility. The relative effectiveness of different modes of warm-up, however, is unknown. The purpose of this study was to evaluate the effectiveness of superficial heat, deep heat, and active exercise warm-up prior to stretching compared with stretching alone on the extensibility of the plantar-flexor muscles. SUBJ...

Ravindran R. BMJ Case Rep 2017. doi:10.1136/bcr-2014-203856 Description Prolonged abdominal heat application in an individual with diabetes and gastroparesis leads to the development of erythema ab igne. Practitioners should be aware of the various ways that erythema ab igne can present. Erythema ab igne is due to prolonged heat exposure (43–47°C) which causes damage to superficial vascular ple...

Article history: Received: 16.9.2015. Received in revised form: 20.2.2016. Accepted: 24.2.2016. Symmetrical rubber buffers mounted on a tracktype bulldozer are used in passive damping for the reduction of vibrations. As heat accumulation due to hysteresis may occur in continuous operation distributions of three typical cases were evaluated by FEM. The simulation result shows that hysteresis–rel...
