2014 A review of low temperature techniques as applied to neutron scattering studies is presented. Methods of temperature measurements especially carbon thermometry are discussed. Problems of heat transfer are treated in detail for different kind of samples and some solutions are proposed. Revue Phys. Appl. 19 (1984) 677-683 SEPTEMBRE 1984, The number of neutron scattering studies at temperatur...

Introduction: Cassini ISS imaged the surface of Io in eclipse by Jupiter in late 2000 and early 2001 and obtained multiple-filter images over timescales of hours. Images like these have been used to study the temperature and variability of the numerous hotspots on the surface [1, 2, 3]. For example, Pele was found to be an active lava lake with most likely basaltic lava composition [2]. New Hor...

The temperatures of various parts of the body, as determined with the ordinary clinical thermometer are, in general, different, and the differences are not always consistent. We cannot assume, therefore , that such measurements give a true index of the mean internal temperature of the body, which may perhaps best be identified with the temperature of the blood flowing in large blood vessels. Mo...

We report on the preparation of the first complete extreme temperature Hall sensor. This means that the extreme-temperature magnetic sensitive semiconductor structure is built-in an extreme-temperature package especially designed for that purpose. The working temperature range of the sensor extends from -270 °C to +300 °C. The extreme-temperature Hall-sensor active element is a heavily n-doped ...

in this investigation, using mann – kendall graphical-statistical test, which is one of the proposed methods of world meteorological organization (wmo) for time series analysis, the change trend of long – term mean of annual minimum and maximum temperatures in iran will be studied. to evaluate this trend and access a suitable pattern in this situation, average of annual minimum and maximum ...

freezing causes changes on chemical and microbial quality of butter. in this research, effects of two different temperatures -9 and -18oc on changes of moisture, fat, acidity and peroxide value and also coliform and psychrotrophic microorganisms in frozen butter were studied. results showed that values of moisture and fat during 7 months of frozen storage at two temperatures decreased 1.8% and ...

750 required to kill the tumor while in the case of neutron rays only = 2.9 times the 260 mouse lethal dose produces the same tumor effect. This comparison of dosage ratios indicates that neutron rays may be more selective than x-rays in their effects on this tumor. We are indebted to Dr. Francis Carter Wood for specimens of Sarcoma 180, and to Dr. R. S. Stone for his interest and for the x-ray...

The field of cavity optomechanics, which concerns the coupling of a mechanical object’s motion to the electromagnetic field of a high finesse cavity, allows for exquisitely sensitive measurements of mechanical motion, from large-scale gravitational wave detection to microscale accelerometers. Moreover, it provides a potential means to control and engineer the state of a macroscopic mechanical o...
