The intent of the stored energy test (SET) is to provide information on the potential for burn injury for a firefighter as a result of prolonged exposure in a structural fire within a room which has not reached a flashover condition. The SET attempts to simulate a firefighter in these conditions suddenly compressing a…

The effects of cotton fabric grafting with hydroxyethyl methacrylate (HEMA) and treatment with polycarboxylic acids (BTCA and CA) are studied. FTIR analysis confirms the successful graft copolymerization of HEMA onto cotton fabrics. Moisture regain decreases as the graft add-on increases, but the mechanical properties…

Low-rate dynamic contact angles on poly(t-butyl methacrylate) (PtBMA) were measured by an automated axisymmetric drop shape analysis profile (ADSA-P). The solid surface tension of PtBMA is calculated to be 18.1 mJ/m2, with a 95% confidence limit of ±0.6 mJ/m2. This value was compared to previous results with different…

This paper examines the design of the horizontal-axis washing machine by means of parametric modelling and the description of the motion of articles, e.g. clothes, in it during the washing process. A series of dimensionless factors is determined that characterise the horizontal-axis washing machine. These parameters c…

The preparation of ultra high purity niobium (“UHP-Nb”) from commercial starting materials (niobium metal or Nb2O5) requires the elimination of all impurities down to the ppm, sub-ppm or even ppb level. This is possible only by application of a complex technology comprising the following essential processing steps:(1)…

We developed the novel positive photosensitive polyimide coatings "PW-1000". The coatings have alkaline developablity as well as fine resolution. The coatings have wide focus margin also. In addition to these photolithographic performances, the "PW-1000" has good heat stability, solution stability, and plasma etching…

Five new megastigmane glucosides and one of their aglycones were isolated, along with (6S,9R)-roseoside, from the polar fraction of the leaves of Asclepias fruticosa, and the structures were determined by spectroscopic methods. Most of them have an epoxy-linkage between C-5 and C-11. The configurations at C-3 and C-9…

A series of polystyrene-based cationic copolymers (PSCC) were synthesized by copolymerization of styrene and the cationic comonomer vinylbenzyl trimethylammonium chloride. These copolymers can be used as internal paper sizing agents in a broad pH range. The effect of the charge density on the PSCC colloid properties w…

Many attempts to upgrade polystyrene have been made in the past. One of the last and most popular examples is the upgrading of polystyrene by stereo-controlled polymerization of styrene monomer, yielding a syndiotactic material. But the property profile of polystyrene can also be improved by stiffening the polymer cha…

The power loss characteristics of Mn-Zn ferrites were observed up to 1 MHz at 25 mT as a function of temperature. At 100 kHz the temperature at which the power loss minimum occurred was near 70/spl deg/C, at 500 kHz 50/spl deg/C and at 1 MHz even lower. The contribution of eddy current loss to the temperature dependen…

The chemical bond in ferroelectric ABO3 perovskites has been considered as a mixed ionic-covalent one. The effect of covalency on the structure has been analyzed using valence bond theory. A particular attention has been paid to the π bond formation and resulting distortion of the lattice. A role of two ferroelectrici…
