Critical gradient formula for toroidal electron temperature gradient modes

Physics of Plasmas, 2001
Under certain conditions, the electron heat transport induced by electron temperature gradient (ETG) streamers is sufficiently large and sensitive with respect to the normalized electron temperature gradient to represent a possible cause for electron temperature profile consistency (“stiffness”).

Temperature‐gradient observations

Eos, Transactions American Geophysical Union, 1943
In connection with studies of evaporation, which the Soil Conservation Service is conducting, it was found necessary to make a detailed study of the temperature‐structure of the lower atmosphere.In order to achieve the degree of sensitivity respired for the study, thermocouple‐junctions constructed of No. 30 copper and constantan wire were used.

Environmental Temperature and the Ocular Temperature Gradient

Archives of Ophthalmology, 1965
Introduction Previous studies1,2have indicated the existence of ocular temperature gradients. These were of two primary types; the cantral, anterior-posterior gradient across the globe from cornea to orbit and the peripheral, superior-inferior gradient extending across the anterior chamber mainly created by the lids over-riding the superior and ...

Temperature Gradients

1934
Abstract The first part of this paper consists of a brief discussion of the correlation of temperature with structure and the possible causes of temperature variations over local and regional areas. The second part of the paper consists of a table in which are summarized certain constants deduced from the temperature ...

Temperature gradient assisted magnetodynamics

Physics Letters A, 2012
Abstract Energy excitations in ferromagnets are studied in case a temperature gradient is coupled to the local magnetization. Due to different time scales only the coupling between the spatially varying part of the temperature field and the magnetization is relevant.

Toroidal ion temperature gradient mode stability at large temperature gradients

Physica Scripta, 1997
It is well known that the ion temperature gradient (ITG) or ηi mode (ηi = [(1/Ti)(dTi/dr)]/ [(1/n0)(dn0/dr)] = Ln/LT, Ln = density scale length, LT = temperature scale length) has an instability threshold (ηilow) around one for density scale lengths of the order of the magnetic field curvature radius LB.

Temperature gradient zone melting

Progress in Crystal Growth and Characterization, 1983
Abstract The paper presents the main regularities of temperature gradient zone melting (TGZM). Theoretical and experimental studies of kinetics and stability of the process and the redistribution of impurities and the main components of solid solutions in TGZM are reviewed. Special attention is paid to the application of the method to growing perfect

On-chip temperature gradient interaction chromatography

Journal of Chromatography A, 2006
This paper reports the first integrated microelectromechanical system (MEMS) HPLC chip that consists of a parylene high-pressure LC column, an electrochemical sensor, a resistive heater and a thermal-isolation structure for on-chip temperature gradient interaction chromatography application.

Temperature Gradients in the Hypothermic Dog

American Journal of Physiology-Legacy Content, 1956
Temperature gradients have been studied in 15 dogs subjected to hypothermia. In six of these experiments it was possible to maintain the rectal temperatures at approximately 25°C for from 4.5–34 hours. The results obtained indicate that there was little extraction of heat from the skin during progressive hypothermia.
