A temperature-sensitive cardiac pacemaker

Journal of Medical Engineering & Technology, 1983
An artificial cardiac pacemaker which is sensitive to the temperature of blood in the right atrium has been fabricated. For a temperature change of 20 degrees C the circuit achieves 90% of its final response within a period of 18 s. In the authors' opinion this is satisfactory since changes in blood temperature are generally small.

A temperature-sensitive respiratory alarm

Clinical Physics and Physiological Measurement, 1983
Describes a novel alarm which is designed to monitor respiration in a patient undergoing intermittent positive pressure ventilation. The alarm operates by sensing the temperature differences between the inspired and expired gas using a thermistor mounted close to the point in the breathing circuit where the patient connection is made. It offers several

High-performance Pr3+-doped scandate optical thermometry: 200 K of sensing range with relative temperature sensitivity above 2 %·K-1.

ACS Applied Materials and Interfaces, 2019
Nowadays, for lanthanide fluorescence thermometry, high relative temperature sensitivity (Sr) and wide sensing range are urgently required in practical applications. Herein, a Pr3+-doped scandate (Pr3+:CaSc2O4) luminescent thermometer is proposed and the

Effect of temperature on sensitivity of the finger

Journal of Applied Physiology, 1963
Subjects reported the detection of impacts from objects falling upon the ball of the finger. At a given point on the skin a falling weight of 1 mg might be detected after falling 10 mm, and twice the weight would then be detected after falling 5 mm. Droplets of mercury expelled by a Scholander micrometer burette afforded one series of measurements. On

Temperature Sensitivity of Myosin and Actomyosin

Canadian Journal of Biochemistry, 1973
The thermal denaturation of myosin and actomyosin was studied by active site analysis (enzymatic activity) and measurements were related to overall conformational changes (viscosity) over the temperature range 19–65 °C. The role of sulfhydryl (SH) groups on the temperature-induced denaturation of actomyosin was investigated. The temperature of maximum

Temperature-Sensitive Hydrogels [PDF]

American Journal of Drug Delivery, 2005
Thermo-sensitive polymers are appealing materials for several therapeutic applications, such as in regenerative medicine and in situ drug release. These macromolecules are characterized by the ability to undergo swelling/deswelling processes during temperature change-induced phase transitions.

Pseudofacilitation: A temperature-sensitive phenomenon

Muscle & Nerve, 2000
With sustained isometric exercise, compound muscle action potential (CMAP) amplitude of normal subjects may increase, a phenomenon known as pseudofacilitation. To explore the mechanism of pseudofacilitation, the effect of exercise combined with focal heating and cooling of abductor pollicis brevis was examined in 10 normal subjects.

Generation of a Temperature-Sensitive cSRC

Virology, 1993
We have created retroviruses encoding a temperature-sensitive variant of the cSrc protein, and of its activated allele cSrc(Y527F). Cells expressing the activated allele harboring this mutation displayed a transformed phenotype when grown at 34 degrees, but not at 39 degrees, as quantitated by measuring the susceptibility of the cells to contact ...

Investigation on the temperature sensitivity of the S-CO2 Brayton cycle efficiency

Energy, 2019
With the development of compact heat exchangers in the past few decades, S-CO2 recompression Brayton cycle has attracted much attention. However, the cycle efficiency of the traditional S-CO2 recompression Brayton cycle is sensitive to the compressor ...

Analyzing and Correcting Spectrometer Temperature Sensitivity

Journal of Magnetic Resonance, 2001
Stability and reproducibility of the spectrometer are fundamental to the success of many modern NMR experiments. Variation in room temperature is a particularly important source of instability, in part because it can cause coherent artifacts in NMR spectra.
