Abstract The present investigation deals with the tensile mechanical properties of the melt‐blended polyethylene/polystyrene pair as controlled by poly(hydrogenated butadiene‐ b ‐styrene) copolymers. It is clearly demonstrated that moderate amounts of these copolymers (2–10%) significantly increase both the ultimate s…

Abstract Preparation of the μ-cyano dinuclear complexes MI[F(en or tn)2Cr(NC)Cr(CN)5]·nH2O from the double complexes MI[CrF(H2O)(en or tn)2][Cr(CN)6]·nH2O was carried out both in the solid state and in solution, where MI is Li+, Na+, K+, or Rb+ ion; en and tn stand for 1,2-ethanediamine and 1,3-propanediamine, respect…
Although fiber content is one of the most important factors influencing consumers' clothing purchase decisions, little research has been conducted to substantiate a preference for natural, synthetic, or blended fiber contents or to link perceptions offibers with any particular market segment. For this study a sample w…
This paper considers in detail the influence of fabric side tension in the single yarn pull-out test and the associated microdisplacements when a single yarn is progressively pulled from a weave. The side tension force per yarn has been varied from near zero to values approximately one-half of the value required to co…

The effect of soft additives (Pb, Bi) on the machinability of low carbon resulphurised free machining steels has been investigated using the plunge machinability test. The cutting and thrust forces and chip thickness were measured as a function of cutting speed in the steels having various contents of Pb and Bi. Unexp…
The relationship between Si in soil solution and allophane and halloysite content was studied by using a drainage sequence of three New Zealand soils from rhyolitic volcanic alluvium. Clay mineralogy was compared with soil colour and drainage. Allophane and halloysite contents of two morphologically similar soils from…

Fouling of heat transfer equipment poses a major problem in the food and especially the dairy industry. A review of recent progress made in the study and understanding of fouling and cleaning mechanisms in relation to exchangers and heat exchange surfaces in contact with milk components is given. The first part descri…

Chemically stabilized β‐cristobalite has been synthesized in the Na 2 O‐Al 2 O 3 ‐SiO 2 and CaO‐Al 2 O 3 ‐SiO 2 systems. Highly reactive chemical precursors in the gel and zeolitic state are thermally transformed to stabilized β‐cristobalite crystalline solutions in each system. High‐temperature X‐ray diffraction, pha…
The thermodynamics of the enzymatic hydrolysis of cellobiose, gentiobiose, isomaltose, and maltose have been studied using both high pressure liquid chromatography and microcalorimetry. The hydrolysis reactions were carried out in aqueous sodium acetate buffer at a pH of 5.65 and over the temperature range of 286 to 3…
Models incorporating different levels of sophistication are presented for predicting the surge distribution in motor stator windings. Results predicted by these models have been validated against experimental results. Simple models, which provide insight into the relevant mechanisms, are presented for estimating the i…
Abstract The distribution of Fe 3+ -kaolinite, Al-goethite and Al-hematite and their contents of Fe and Al in bauxites and ferricretes are controlled by water activity, dissolved silica activity, temperature and particle size. The proposed model, based on ideal solid-solution equilibria in the Fe 2 O 3 -Al 2 O 3 -SiO…
Factors concerning the stabilization of the tetragonal and cubic phases, metastable at room temperature, with respect to the monoclinic stable phase in ultrafine zirconia powders are studied. The importance of Na + ions in the initial zirconia amorphous gel in obtaining a cubic phase has been confirmed. By an X‐ray di…
