The three different force-calculating methods based on magnetic field analysis using the finite-element method are evaluated using a fundamental model, which is constructed with permanent magnets and iron plates. The magnetic force for the model is calculated by Maxwell's stress tensor method, the virtual work method,…

The continuing development of the textile and clothing manufacturing industries depends in no small measure on the successful implementation of reliable objective methods for the specification, prediction and control of fabric quality and performance attributes. In the last decade, we have seen several notable example…

A methodology for predicting the catalytic metal profiles resulting from a multicomponent impregnation was developed. Each ingredient was classified on the basis of its influence on the adsorption process. A multicomponent adsorption-transport model was used to predict the effects of a competing acid on the catalytic…
The long time dynamical response of a nematic liquid exhibiting banded textures (inversion walls) during the twist Freedericksz transition is presented. A dynamical model of approach to equilibrium through defect interaction and the resulting dissolution of the banded textures is presented. A linear stability analysis…
The Raman spectra of a series of glasses in the system MoO 3 ‐P 2 O 5 and the polyerystalline compounds molybdenum metaphosphate (MoO 2 (P0 3 ) 2 ) and molybdenum pyrophosphate ((MoO 2 ) 2 P 2 O 2 ) are reported. The spectra indicate that traces of P=O and phosphate chains are present only in glasses having less than…
Synthesis and Structures of Bis(triethanolamine)lanthanide Complexes Three novel lanthanide triethanolamine chelates {Ln[N(CH 2 ‐CH 2 OH) 3 ] 2 }(CF 3 SO 3 ) 3 (Ln = Pr, 1 ; Yb, 2 ; Lu, 3 ) were synthesized from Ln(CF 3 SO 3 ) 3 and triethanolamine in THF. The structures of 1 and 2 were determined by single‐crystal X‐…

Abstract The thermal behaviour of sepiolite and palygorskite treated with butylamine was investigated by DTA, TG and EGA-MS under a flow of air and N 2 . It was shown that the amine was adsorbed by the clays, penetrating into the pores and replacing zeolitic and bound water. The presence of amine in the pores shifted…

Kathon CG was determined in 156 of the most commonly used cosmetic products in Denmark. 42% of the cosmetic products were found to contain Kathon CG. Kathon CG was present in 48% of "rinse off" and 31% of "leave on" cosmetic products. The 3:1 ratio of chloromethyl isothiazolinone (CMI): methyl isothiazolinone (MI) in…
Quantitative and qualitative changes in collagen synthetic activity by rabbit arterial smooth muscle cells were monitored during spontaneous phenotypic modulation from days 2-15 of culture. The cultured smooth muscle cells transformed into a synthetic phenotype, reaching a maximum of 94.6% on day 4, and then gradually…
Cross sections for the production of ${\mathrm{O}}^{\mathrm{\ensuremath{-}}}$ from ${\mathrm{N}}_{2}$O by the process of dissociative electron attachment have been measured for electron-impact energies ranging from 0 to 50 eV. Three new ${\mathrm{O}}^{\mathrm{\ensuremath{-}}}$ peaks are observed. The present data abov…
ABSTRACT A mathematical procedure was developed to estimate heat transfer coefficients for heated rotating cans of food comprised of a liquid and spherical particles. The method uses experimental data for only the fluid temperature, and heat transfer coefficients are obtained by comparing predicted with experimental f…
Abstract An investigation of the diffusion competition between solvent and nonsolvent in a coagulation bath is presented for the formation of a new cellulosic fiber by wet‐spinning. The system consisted of the spinnable cellulose solution with a mixture of liquid ammonia/ammonia thiocynate as the solvent and low‐molec…
This book deals with the methods of X-ray production at a level which is accessible to advanced undergraduates and researchers who use X-rays. It also discusses the fundamentals of these physical properties from an experimental viewpoint which is not covered in more specialised texts. The book begins with a survey of…
Five basic methods of synchronous motor torque measurement are described. The first method is the traditional mechanical measurement using an accelerator; the second method involves an electrical technique using search coils as flux sensors; the remaining techniques employ either terminal voltage and current or input…
Abstract New reaction products have been generated on polyethylene and polystyrene surfaces using a novel two‐step process. The first stage involves exposure to a downstream nitrogen plasma, and the second to either ozone or a corona discharge. It is observed that each of the two‐step reactions yields very different r…
