The conduction mechanism near liquid-nitrogen temperature has been identified as the hopping of charge carriers from the charged trap centers to empty traps near the Fermi level.Type of Medium: Electronic ResourceURL: -

ISSN: 1750-3841Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionProcess Engineering, Biotechnology, Nutrition TechnologyNotes: Three varieties of soybean (Bragg, Punjab-1 and Lee) were chemically evaluated for their protein quality from the amino acid data, solubility classes of proteins, chemical score, essential amino acid index, requirement index and electrophoretic pattern of proteins. Cotyledon, the major component of seed, accounted for about 93% of tryptophan and methionine of the whole seed. Glycinin as the predominant fraction of soy protein (about 63% of total protein) contained 73% and 71% of the amount of methionine and tryptophan of the whole seed, respectively, but was deficient in methionine. Albumin, constituting about 12% of total soy protein, was also deficient in methionine but was quite rich in tryptophan. Prolamine fraction of soy protein was rich in methionine and tryptophan. On the other hand, glutelin was the poorest in these amino acids. Soy protein contained a balanced amino acid pattern with the exception of methionine which was found to be the main limiting amino acid. The electrophoretic pattern of albumin fraction of Punjab-1 and Bragg differed from that of Lee while there were no varietal differences in the pattern of whole seed proteins and glycinin. Punjab-1 appeared to be better in its protein quality based on its higher values of chemical score, essential amino acid index and requirement index. The present investigation has revealed that chemical evaluation is comparable to biological evaluation and can serve as a good index in the assessment of protein quality of food grain.Type of Medium: Electronic ResourceURL: -

ISSN: 1460-2695Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract— Experiments have been performed on specimens subjected to strain cycles similar to those experienced by sub-surface elements of material in rolling/sliding contact. It has been observed that if the strain cycle is closed then failure takes place by low cycle fatigue and the Coffin-Manson relationship may be used to predict the number of cycles to failure. If however, the strain cycle is open, so that the material accumulates unidirectional plastic strain (the situation known as “ratchetting”) a different type of failure, which is termed ratchetting failure may occur. It occurs when the total accumulated plastic strain reaches a critical value which is comparable with the strain to failure in a monotonic tension test. The number of cycles to failure under these circumstances may be estimated by dividing this critical strain by the ratchetting strain per cycle. It is suggested that low cycle fatigue and ratchetting are independent and competitive mechanisms so that failure occurs by whichever of them corresponds to a shorter life. The results of both uniaxial and biaxial tests reported in the literature have been re-evaluated and these, together with new data on biaxial tests on copper, found to be consistent with this hypothesis.Type of Medium: Electronic ResourceURL: -

Published 2003Staff ViewISSN: 1460-2695Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: A computer model, which simulates the ratcheting wear of a ductile material subject to repeated loading, is presented and discussed in detail. Variation of material properties is a feature of the model, failure by ductility exhaustion occurring at isolated points or extending regions of failure. Such regions form crack-like features. Mechanisms for removal of weakened material from the surface as wear debris are described. The wear process causes a degree of surface roughness. The simplicity of the model enables simulation of millions of load cycles in only a few hours' computer time. The computer model is used to study the effect of partial slip on wear rate. When creepage is relatively low, the wear rate increases sharply with creepage. When creepage is relatively high, the wear rate is largely insensitive to the creepage.Type of Medium: Electronic ResourceURL: -

Rolling contact fatigue, especially squat defects, grinding, corrugations and lubrication, have been considered. The understanding has been developed through a combination of theoretical modeling, laboratory-based experiments and field trials. Measures have been introduced to mitigate the detrimental effects of these problems and are resulting in benefits to the Japanese railway companies. However, more work is required to better understand wheel rail interface problems and to provide effective solutions.Type of Medium: Electronic ResourceURL: -

Published 2003Staff ViewISSN: 1460-2695Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Results from the European 5th frame research project ‘INFRA-STAR’ are presented. The goal of the project is to prevent rolling contact fatigue (RCF) and to reduce squeal noise in curves by applying an additional surface layer material on the top of the railhead, resulting in a two-material rail. In INFRA-STAR, a dynamic train–track interaction model is used to provide the contact forces. Wheel-rail profiles, wheel-rail friction, vehicle data, track data and operating conditions are included to calculate the wheel-rail contact forces and spin moments, contact positions and load distributions in the contact patch. The contact pressure, friction coefficient, coating thickness, material properties of the coating and the rail material are used in finite element calculations and shakedown theory to calculate shakedown limits, which are then used to predict the RCF performance of the system. The paper details the work on theoretical modelling, twin disc testing, metallurgical research and field testing completed to date (August 2002, the project just passed midterm). The development of the surface layer application methods that are used, and the further objectives of the INFRA-STAR project, are discussed.Type of Medium: Electronic ResourceURL: -

Published 2003Staff ViewISSN: 1460-2695Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Plastic flow of near-surface rail material under contact loading is a feature of rail–wheel contact, and severe flow typically leads to both wear, and the initiation and development of small surface-breaking cracks. This paper presents results from a ratcheting based computer simulation, which has been developed to allow the simultaneous investigation of wear, crack initiation and early crack propagation. To identify repeatably small crack-like flaws, image analysis is applied to the visual representation of the wearing surface generated by the model. This representation shows a good similarity to traditional micrographs taken from sections of worn surfaces. The model clearly reveals the interaction of wear with crack development, processes which are linked because wear truncates surface-breaking cracks, and can completely remove small surface-breaking cracks.Type of Medium: Electronic ResourceURL: -

Flours of triticale varieties contained higher amounts of protein, crude fibre, total and available lysine, and lower contents of gluten than wheat. Losses of amino acids due to chapati making were negligible. As the proportion of triticale flours in chapatis increased the protein quality of chapatis improved.Type of Medium: Electronic ResourceURL: -
