The effects of cooling on neuromuscular function and performance during gait are not fully examined. The purpose of this study was to investigate the effects of local cooling for 20 min in cold water at 10°C in a climate chamber also at 10°C on maximal isometric force and electromyographic (EMG) activity of the lower leg muscles. Gait ground reaction forces (GRFs) were also assessed. Sixteen he...
We present measurements of the instantaneous local heat flux in highly turbulent Rayleigh–Bénard (RB) convection in air (Pr = 0.7) for aspect ratios in the range 1.136 0 6 9.00 and for Rayleigh numbers in the range 1.3× 109 6 Ra 6 9.6× 1011. The measurements have been carried out simultaneously at the surfaces of the heating and the cooling plate using a commercial sensor whose diameter is 360 ...
AIM Up to now, modern miniature cryoprobes have been used successfully for local destruction of soft tissue tumors without damaging adjacent healthy tissue. In this study, the methodology of cryoablation was applied to bone and the freezing effect as well as the cooling capacity of the probe was examined in vivo and in vitro. METHODS Freezing was performed by cooling one or two probes, with a...
Rapid uniform cooling of the heart is the most important requirement of any method using local hypothermia for protection of the myocardium during open intracardiac surgery. We report the construction and operation of a recirculation cooling circuit comprising a reservoir, pump, and heat-exchanger for this purpose. It is operated by the perfusionist and can deliver up to 1 litre of fluid per mi...
Non-local heat transport experiments were performed in Alcator C-Mod Ohmic L-mode plasmas by inducing edge cooling with laser blow-off impurity (CaF2) injection. The non-local effect, a cooling of the edge electron temperature with a rapid rise of the central electron temperature, which contradicts the assumption of “local” transport, was observed in low collisionality linear Ohmic confinement ...
Rapid cooling of the brain in the first minutes following the onset of cerebral ischemia is a potentially attractive preservation method. This computer modeling study was undertaken to examine brain-cooling profiles in response to various external cooling methods and protocols, in order to guide the development of cooling devices suitable for deployment on emergency medical vehicles. The criter...
[1] Observational evidences are presented to show a significant atmospheric diabatic cooling in the Indian summer monsoon (ISM) region after the 1997/1998 El Niño. This study investigates the cause of this decadal cooling and its impact on the East Asian summer monsoon (EASM). After 1997/1998, the abnormal sea surface temperature warming in the western Pacific, which is not fully demonstrated i...
Calculations of iron losses in the electrical machines are normally based on experimental characteristics of core material used in the machines. These methods with simplified machine analysis approximations are usually employed for calculation of total iron losses of electrical machines whilst local flux densities and corresponding local iron losses especially when designing of the machine and ...
BACKGROUND Fever in neurocritical care patients is common and has a negative impact on neurological outcome. The purpose of this prospective observational study was (1) to evaluate the practicability of cooling with newly developed neck pads in the daily setting of neurointensive care unit (NICU) patients and (2) to evaluate its effectiveness as a surrogate endpoint to indicate the feasibility ...
Study selection and assessment: randomised controlled trials (RCTs) that compared mild therapeutic hypothermia (local or systemic therapeutic cooling [using a fluid filled cooling blanket, a ‘‘Bear Hugger’’ air cooling device, ice water lavage, or combination, or other method] to a target temperature (34– 35 C̊ for >12 hours beginning on admission to the intensive care unit or when intracranial ...
