This lecture addresses the concept of form factor in magnetic scattering of thermal neutrons, analyzing its meaning, discussing its measurement by polarized neutrons and detailing its computation for the ions by the spherical tensor operator formalism.

This study was conducted on a thermal exposure chamber designed for assessing workers' thermal hazard. In order to assess the efficacy of the studied chamber, three environmental conditions were selected to simulate high, middle and low thermal impact situations, with air temperatures (Ta) of 43.12, 36.23 and 25.77 masculine C, globe temperatures (Tg) of 44.41, 41.07 and 29.24 masculine C, rela...

Background and Aims: The safe, potent and effective live vaccines against Measles, Mumps and Rubella as important childhood diseases have been available for several decades. Several factors can affect the thermal stability of lyophilized vaccine. Methods: In this study, the effect of residual moisture on thermal stability of 61 batches of MMR vaccine was investigated using an accelerated ...

The arrangement of the centers of the molecules in the crystal is that corresponding to the diamond structure. Each molecule is surrounded tetrahedrally by four molecules. If we consider a molecule as roughly tetrahedral in shape with similar orientation to the tetrahedron formed by the four beryllium atoms, then the adjacent molecules are so oriented as to present tetrahedral faces to one anot...

AMONG the various well-known shocku producing traumata, such as hemorrhage, crush and burns, most experimental data has been collected from studies on hemorrhage. • Although experimental studies after burn injury have been made', the accumulated information is much less for this shock-producing agent. Particularly lacking is an assessment of the factors concerned in the very early stages of the...

The major factors limiting the thermal performance of passive two-phase heat–spreading devices are the ability of the wick structures to transport liquid by means of capillary forces and the thermal resistance posed by the wicks. Nano-scale geometric enhancements to the wick structure, through the use of carbon nanotubes and metallic nanowires, promise to enhance the capillary transport while a...

in this study, the effective factors on warpage in short fibre reinforced thermoplastic composites has been studied. first of all, the effective factors in manufacturing process were detected and then in order to decrease the number of experiments, the approach of design of experiments has been applied. by using micromechanics theory in composites and coefficients of thermal expansion models, a...

this review paper provides researcherwith a comprehensive information about the carbon nano tubes and the catalyst parameters that influences theproduction and morphology of the of carbon nano tubes.carbon nanotubes, referred to as cnts, are one of the most important materials used in electrical, mechanical, thermal, chemical and textile industries. since discovery of cnts in 1991, many scienti...

The fluctuation characteristic of airflow is one of the important factors to influence the indoor thermal environment and human thermal comfort, which attracts researchers’ interest in these years. This paper introduces the recent researches on the fluctuation characteristics of airflow conducted in Tsinghua University. Results show that there exist obvious differences and interesting connectio...
