Equipment Temperatures in Hot Completions
SPE Offshore Europe, 1991ABSTRACT This work illustrates the application of accepted relationships to thermal problems in production equipment. Previous work has shown that relationships which were developed for much simpler cases are adaptable to oilfield problems.

Taking the temperature of hot carriers
Science, 2020Nanophotonics Hot carriers are expected to arise in plasmonic nanostructures because of the nonradiative decay of surface plasmons. However, identifying and determining just how “hot” these carriers actually are has been challenging. Reddy et al.

Tuning Temperature and Size of Hot Spots and Hot‐Spot Arrays
Small, 2010AbstractBy using scanning thermal microscopy, it is shown that nanoscale constrictions in metallic microwires deposited on an oxidized silicon substrate can be tuned in terms of temperature and confinement size. High‐resolution temperature maps indeed show that submicrometer hot spots and hot‐spot arrays are obtained when the SiO2 layer thickness ...

Hot science at low temperatures
Physics World, 1992What do superconducting films, the fungal infestation of leaves and storage properties of pharmaceutical creams have in common? The answer is that the characterisation of all of these materials can be assisted by the use of low-temperature scanning electron microscopy (LT SEM).

Duration of Very Hot Temperatures *
Bulletin of the American Meteorological Society, 1952Maximum temperatures on very hot days in hot-desert areas are similar in duration and time of occurrence to maximums on cooler days: they occur around three hours after noon, and the temperature (as measured to the nearest whole degree by standard thermometers) remains at the maximum for about two hours.

The Temperature Sensitivity of Hot Wires
1978Significant errors in measurements of some velocity and joint velocity-temperature statistics arise from the non-negligible contamination of the measured hot-wire velocity signal by concomitant temperature fluctuations. Measurements of the temperature sensitivity of hot wires operated at high overheat ratios are considerably more difficult to obtain ...

Hot questions of temperature bias
Nature, 2008An unseen measurement bias has been identified in global records of sea surface temperature. The discrepancy will need correction, but will not affect conclusions about an overall warming trend.

Dependence of hot carriers temperature on lattice temperature in CdS
Solid State Communications, 1973Abstract Non-equilibrium carrier distributions were obtained in CdS at various temperatures from 77 to 400K. A study is made of the influence of the lattice temperature on the carrier temperature. It is found that the higher the lattice temperature the lower is the difference between carrier and lattice temperatures, though carriers are always ...

Hot water epilepsy occurring at temperature below the core temperature
Brain and Development, 2006A 6-year-old girl had water reflex epilepsy occurring at lower temperature than the core temperature. Seizures episodes consisted of a loss of consciousness absence followed by left predominant hypotonia with right fronto-temporal high voltage slow waves on the ictal-EEG.

A constant temperature hot-wire anemometer
Journal of Physics E: Scientific Instruments, 1987A constant temperature anemometer is described which is designed to operate hot wires with diameters in the range 0.63-5 mu m. A special feature of the design is the use of separate current sources to supply the different halves of the bridge. This feature eliminates the need for dynamic stability compensation, necessary for commercial constant ...
