We have compared deep body temperature (DBT) measured at the forehead with the core temperatures of the nasopharynx, oesophagus and rectum during the warming phase of cardiopulmonary bypass (CPB) (moderate hypothermia of 26.7-29.6 degrees C) in 12 patients. DBT was measured transcutaneously by an insulated thermistor probe that created an area of zero thermal flow between skin and subcutaneous ...

Abstract This work introduces a wearable, highly sensitive human body temperature sensor. The proposed thermistor sensor employs poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) as sensing layer and interdigitated electrodes (IDEs) from Silver nanoparticles deposited on Polyimide (PI) Epson glossy paper substrates. IDEs were patterned using inkjet printer Drop-on-demand PiXDRO...

The laryngeal chemoreflex (LCR), elicited by a drop of water in the larynx, is exaggerated by mild hyperthermia (body temperature = 40-41 degrees C) in neonatal piglets. We tested the hypothesis that thermal prolongation of the LCR results from heating the nucleus of the solitary tract (NTS), where laryngeal afferents first form synapses in the brain stem. Three- to 13-day-old piglets were dece...

Flexible electronics have gained popularity because of their capability to combine softness and functionality. Soft resistive sensors are susceptible mechanical stimuli detecting temperature selectively remains a challenge. In this study, soft flexible thermistors developed for changes based on the positive coefficient (PTC) effect, selectively. By thermomechanical analysis differential scannin...

1. The experiments of Madsen and Watabiki on the effect of temperature on the phagocytosis of bacteria are discussed and a new analysis of their curves is given, showing that the rate of phagocytosis is very nearly a logarithmic function of the temperature from 0 degrees to 35 degrees C.; i.e., Q(10) is constant over that range and is equal to 2.0. 2. New experiments are reported on the effect ...

number of bacteria ingested at the close of the experlment(instead of the maximum number of bacteria present, which, one is led to infer, was larger than A even at the higher temperatures) and x equal, as usual, to the number of bacteria ingested in time, T. Considering their method of analysis it is not surprising that they found it impossible to calculate the temperature coefficient of phago•...

Watershed modeling has become an important tool for researchers. Modeling nitrate transport within drainage networks requires quantifying the denitrification within the sediments in canals and streams. In a previous study, several of the authors developed an equation using a term called a mass transfer coefficient to mathematically describe sediment denitrification. This equation takes into acc...
