Journal of Separation Science, 2006
AbstractA new procedure for determining the calibration function able to relate retention and operative parameters to molecular weight of the species in thermal field flow (ThFFF) under thermal field programming (TFP) conditions is presented. The procedure involves determining the average values of retention parameters under TFP and determining a ...

Micro-Thermal Field-Flow Fractionation
Collection of Czechoslovak Chemical Communications, 2002The effect of miniaturization of the separation channel on the performance of thermal field-flow fractionation (TFFF) is substantiated theoretically. The experiments carried out under carefully chosen experimental conditions proved the high performance of the separation of polymers within an extended range of molar masses from relatively low up to ...

Now in paperback, this text introduces the theoretical framework for describing the quark-gluon plasma, an important new state of matter. The first part of this book is a self-contained introduction to relativistic thermal field theory. Topics include the path integral approach, the real and the imaginary time formalisms, fermion fields and gauge ...

During last few years, there has been a lot of interest in various phenomena at finite temperature, in quantum field theories. These include the early universe cosmology [1,2], astrophysics of compact stars [3] as well as the experimental programs in relativistic heavy-ion collisions in the context of quark gluon plasma (QGP) [4].

Electromagnetic field occupational exposure: Non-thermal vs. thermal effects
Electromagnetic Biology and Medicine, 2013There are a variety of definitions for "non-thermal effects" included in different international standards. They start by the simple description that they are "effects of electromagnetic energy on a body that are not heat-related effects", passing through the very general definition related to low-level effects: "biological effects ascribed to exposure

Abstract After a review of the calculational approaches, the free energy of scalar particles in thermal equilibrium is calculated. The IR behaviour of mass-less scalar fields is examined, finding that a resummation of IR divergent terms is necessary.

Building Science, 1974
Abstract It is possible to describe thermal radiation environment at a point in space using the concept of the radiation field. This paper derives the fundamental parameters of the field, and describes how they may be measured. The use of the radiation vector, or its equivalent the vector radiant temperature, is recommended as a measure of the ...

Thermal fields during regelation
Cold Regions Science and Technology, 1980Abstract Regelation of ice within the soil matrix is a possible mechanism of ice transport during frost-heave. The classical, single-particle, theory of regelation is here extended to transverse, longitudinal, and square infinite arrays of cylindrical particles, for the case, as in soils, where heat-conduction is the rate-governing process.

Anomalous thermal field emission
Technical Physics, 2007The field emissivity of ZrO2/W(100) nanoheterostructures made by applying a thin (≈10 nm) ZrO2 layer on the surface of a needle-like W(100) microcrystal is studied. At a nanoheterostructure temperature of ≈2000 K, electron emission is found to start at a low extracting (Laplace) field (below 50 V/μm).
