Abstract

Steady state creep analysis in a rotating disc with linearly varying thickness has been carried out. The disc under investigation is made of functionally graded composite containing non-linear distribution of silicon carbide particles in a matrix of pure aluminium along the radius of the disc. The creep behaviour of the disc has been described by a threshold stress-based law with a stress exponent as 5. The stresses and strain rates are estimated in the FGM disc and compared with a similar disc but having uniform distribution of reinforcement. The study reveals that the creep response of an FGM disc, in terms of strain rates, is significantly superior to a uniform composite disc. Further, by employing FGM disc with higher reinforcement, the magnitude of strain rates and extent of distortion in the disc could be reduced significantly.

Abstract

A search for the neutral Higgs boson in the processes e(+)e(-) --> Z --> H-0 gamma --> and e(+)e(-) --> Z --> Z*H-0 --> has been performed using 2.8 million hadronic Z decays collected with the L3 detector at LEP from 1991 through 1994. No evidence for these processes has been observed. Upper limits at 95% confidence level for the corresponding cross sections have been set and the results have been compared with theoretical predictions beyond the Standard Model.

Abstract

We report on measurements of e+e− annihilation into hadrons and lepton pairs. The data have been collected with the L3 detector at LEP at centre-of-mass energies between 130 and 189 GeV. Using a total integrated luminosity of 243.7 pb−1, 25864 hadronic and 8573 lepton-pair events are selected for the measurement of cross sections and leptonic forward-backward asymmetries. The results are in good agreement with Standard Model predictions.

Abstract

The results of the searches for neutral Higgs boson production in the process e + e − → Z ∗ H 0 are reported, focusing on Higgs boson masses below 70 GeV. The data sample consists of three million hadronic Z 0 decays collected by the L3 experiment at LEP from 1991 through 1994. No signal is found leading to a lower limit on the mass of the Standard Model Higgs boson of 60.2 GeV at 95% C.L. These results are also interpreted in the framework of the General Two Doublet Model and limits on the nonstandard Higgs boson production through the process e + e − → Z ∗ h 0 are set. A lower limit of 66.7 GeV at 95% C.L. is obtained for the case where the Higgs decays into an invisible final state.

Abstract

In the Indian Power System, voltage and frequency excursion in real time operation is much beyond the statutory limits fixed by the Indian Electricity Rules. Prescribed limits for frequency variation from the declared frequency is 3% while actual variation of 4% is quite common and occasionally goes to 5%, leaving apart some provision for contingencies. On the voltage front, the Electricity Rules prescribe limits for supply at the consumers' premises which is ±6% for the low or medium voltage supply and +10% to -12.5% for the supply at extra high voltage. To meet the obligations as above, Central Planners have made a planning criteria for design of EHV systems to operate within ±5% for 400 kV system and ±10% for 220 kV systems. In real time operation, voltage level of 295 to 300 kV could be seen at a number of 400 kV buses. On the higher voltage side, over voltage protection for the 400 kV lines is usually set at 1.1. Opening of the 400 kV and 220 kV lines is the process adopted to control the overvoltage causing structural deficiency with associated risks in the system and increase in line losses. This paper presents analysis of the problem of low/high voltage in the system and the steps taken by POWERGRID for voltage control in real time operation.

Abstract

The study is aimed at identifying knowledge management factors and developing a flexible strategic framework for knowledge management applicable to SCM. This framework is based on the Measurement Matrix framework of KM suggested by Smith and McKeen (2005). Study of existing KM frameworks was carried out and KM areas identified on the continuum of continuity and change. The data on KM areas on which this study is based was generated through secondary research using published sources and primary research through focused discussion with industry experts and personal interviews with experts from companies selected. A case study of MNCs in electrical and lighting industry is given in this paper validating the KM framework suggested. The research identifies and validates KM areas in terms of continuity and change factors applicable to management of supply chain. The framework suggested can be adapted by the scholars and practicing managers for application in the global context.

Abstract

Low alloy steels of case carburising grade are generally employed in the manufacture of various automotive components. These components have to work under fatigue loading during their service life, which occasionally results in fatigue failures. The present work is aimed at investigating the fatigue crack propagation behaviour of some commonly used low alloy steels in case carburised condition. The crack propagation mechanisms were investigated through fractographic observations on the fractured surfaces of standard fatigue test specimens failed under four-point rotating bending fatigue tests. Despite the presence of residual compressive stresses induced during case carburisation, majority of the fatigue cracks were found to initiate at the surface. Crack initiation was followed by transgranular mode of stable crack propagation for all the steels, while subsequent crack propagation behaviour was found to be dependent on the contents of alloying elements in a given steel. Steels containing higher amounts of chromium were found to exhibit greater tendency towards intergranular decohesion cracking.

Abstract

Creep behaviour of a functionally graded rotating disc has been investigated by using finite element-based Abaqus software. The disc is made of composite containing linear distribution of silicon carbide particles in a matrix of pure aluminium. The creep behaviour of the composite is described by Norton’s power law. The creep response of the FGM disc has been estimated by using Abaqus software and compared with a similar disc but having uniform distribution of silicon carbide reinforcement. It is observed that the radial stress in the FGM disc is higher than the uniform composite disc throughout. However, the tangential and effective stresses in the FGM disc show significant increase near the inner radius but exhibit decrease near the outer radius when compared to a uniform composite disc. The strain rates in the FGM disc are significantly lower than those observed in a similar disc having uniform distribution of reinforcement.

Abstract

With fast changing global economic and socio-political environment and ever increasing customers’ expectation companies are in dilemma as to focus on business continuity or change. The study focuses on identifying the underlying factors affecting the continuity and change forces and suggests on how the organisations in fast food sector can manage supply chain for sustainable business. A study of existing frameworks was carried out and data on underlying factors on which this study is based was generated through secondary research using published sources and primary research through focused discussion and interviews with industry experts using a structured questionnaire. A case study of multinational companies in fast food industry is given in this paper validating the framework suggested. The implications of the proposed framework for both the scholars and practicing managers are highlighted in the concluding part of the paper and can be adapted for applications in the global context.

Abstract

A mathematical model has been developed to investigate steady state creep in a rotating disc having linearly varying thickness. The disc is assumed to be composed of functionally graded (FG) composite containing linearly varying content of silicon carbide particles (SiCp) reinforced in a matrix of pure aluminium (Al). The disc material undergoes steady state creep as described by a creep law based on threshold stress with a stress exponent of 5. The mathematical model developed has been employed to investigate the effect of imposing various linear gradients of SiCp on the creep performance of the FG disc. The study indicates that with the increase in SiCp gradient, the radial stress increases throughout the disc. However, the increase in SiCp gradient results in increase of tangential and effective stresses near the inner radius of the disc but a decrease near the outer radius. The tangential as well as radial strain rates in the FG disc reduce to a significant extent with the increase in SiCp gradient.

Abstract

Continuity and change are the main parameters of any strategy paradigm. Traditionally these have been treated in an ‘either-or’ basis. A lot of work has been done on managing continuity with incremental improvements. In the recent past, significant changes have taken place in the automotive sector in the world and India is no exception. Most of the literature has focused on strategic change and gradual transformation. However, dealing with flexibility, continuity and change has been an area of growing interest as a large number of organisations in the auto sector are faced with turbulence. This research work focuses on study of ‘inward supply chain management’ of a leading auto company in India in order to understand how they are coping up with the forces of continuity and change. Based on this research, the aim is to develop a flexible framework for effectively managing continuity and change in managing automotive supply chains leading to business excellence.

Abstract

Continuity and change are key paradigms of strategic thinking. Most of the literature has focused on strategic change and gradual transformation. Dealing with flexibility, continuity and change has been an area of growing interest to researchers and business organisations to cope with the uncertainty. Outbound automotive supply chain, involving large dealer network, third party logistics and multimode transportation, has become very complex. Vehicle recall, hence, reverse supply chain, has now become common and needs to be included in any strategy for outbound supply chain. This research work focuses on study of outbound supply chain of the largest automotive company in India and understanding how they are coping up with the forces of continuity and change. Based on this research, the aim is to develop a flexible strategic framework for effectively managing forces of continuity and change in outbound supply chains, which can be applied to other similar organisations.

Abstract

Within a context of evolution and the rapid integration of digitization in university publishing, the fields of the humanities and social sciences, and in particular those of textbooks, do not appear to have found a satisfactory distribution model. In this article, we shall attempt to explain in what measure this sector is different from other areas of university publishing and what hypotheses can be put forward for its future development. Having suggested a carving up of the university publishing market, we would like to place it briefly in an international context. On the basis of this finding, we will present the hypothesis of aggregation: why this should be required, why it does not yet exist and which needs it will respond to. We shall conclude by summarizing these points which we believe are key to the development of a digital university offer in France for the humanities and social sciences.

Abstract

St. John‘s Wort (Hypericum perforatum), a perennial flowering plant, has been used medicinally for thousands of years and has most recently been identified as an effective treatment for mild to moderate depression and neuralgic disorders. This work presents a procedure for the isolation of naphthodianthrones from St. JohnÕs Wort by an accelerated extraction and separation of marker compounds by preparative high-performance liquid chromatography (HPLC) with photodiode array detection. The accelerated extraction method minimizes the extraction time and increases the yield, and the marker compounds obtained by preparative HPLC are of 98% purity. The compounds are characterized by liquid chromatography–mass spectrometry (electrospray ionization) and NMR spectra. [ABSTRACT FROM AUTHOR]

Abstract

A'disease'is any impairment of normal physiological function affecting all or part of an organism, especially a specific pathological change caused by infection, stress etc., producing characteristic symptoms. As such disease is a condition of the body or a part of it in which functions are disturbed or deranged. A disease may be caused by excess or deficiency or absence a disease agent which can be a substance or a force. The disease causing biological agents are called parasites and their study is called parasitology. Parasites have a direct impact on humans or on domesticated animals that is almost beyond comprehension. The world has become smalle1,and parasites can travel faster. In some instances our own changing social patterns have also created a more favourable environment for parasites. A variety of factors thus make parasitology a subject of increasing concern for the medical profession. No doubt, medical students and physicians as well as other paramedical professionals such as medical technologists, nurses and public health personnel should have a basic grounding in the diagnosis, prevention and treatment of human parasitic infection. The aim of the present work has been, and continues to be, to provide such fundamental information.

Abstract

A'disease'is any impairment of normal physiological function affecting all or part of an organism, especially a specific pathological change caused by infection, stress etc., producing characteristic symptoms. As such disease is a condition of the body or a part of it in which functions are disturbed or deranged. A disease may be caused by excess or deficiency or absence a disease agent which can be a substance or a force. The disease causing biological agents are called parasites and their study is called parasitology. Parasites have a direct impact on humans or on domesticated animals that is almost beyond comprehension. The world has become smalle1,and parasites can travel faster. In some instances our own changing social patterns have also created a more favourable environment for parasites. A variety of factors thus make parasitology a subject of increasing concern for the medical profession. No doubt, medical students and physicians as well as other paramedical professionals such as medical technologists, nurses and public health personnel should have a basic grounding in the diagnosis, prevention and treatment of human parasitic infection. The aim of the present work has been, and continues to be, to provide such fundamental information.

Abstract

A new spectrophotometric method is described for the determination of acrylonitrile in air. The acrylonitrile present in air is absorbed in dilute potassium permanganate and subsequently oxidized to cyanide. The cyanide thus formed is converted to cyanogen bromide with bromine and reacted with pyridine to form glutaconic aldehyde by breaking of the heterocyclic linkage which is subsequently coupled with sulfanilic acid to give yellow orange polymethine dye. The dye has maximum absorbance at 460 nm and obeys Beer's law in the range 0.5 to 5 ppm. The optimum reaction conditions and important analytical parameters have been studied and successfully applied for the determination of acrylonitrile in air and biological samples.

Abstract

Using the back-calculation approach, simultaneous estimation of rate and breakage distribution parameters has been carried out for a complex pyritic ore from the batch ball mill size distribution data. The ore showed several deviations from the normal grinding behavior: (i) the slope of the Gaudin-Schumann plots in the fine size range varied with the feed size and the grinding time, (ii) the first-order plots showed marked curvature in the initial period of grinding, (iii) the rate parameters did not conform to the relationship S i = Ax α i , even in the fine size range, and (iv) the breakage distribution parameters exhibited a high degree of non-normalizability. The main problem encountered was the choice of a suitable functional form for the breakage distribution function. This paper illustrates the limitations of the two existing functional forms and several other functional forms used in this work, and emphasizes the need for having a more general and practical functional form for the breakage distribution function.

Abstract

A new reagent, malonyl dihydrazide, has been proposed for the extractive spectrophotometric determination of organophosphorus pesticides. The method is based on the estimation of phosphorus present in organophosphorus pesticides by reduction of molybdophosphoric acid to molybdenum blue by using a new reducing reagent, malonyl dihydrazide. The blue-colored dye shows maximum absorbance at 820 and 780 nm in aqueous and extractive systems, respectively. Beer's law is obeyed in the range 0.5–3.6, 0.2–1.4, 0.45–3.2, and 0.45–3.2 ppm for ethyl parathion, methyl parathion, malathion, and quinolphos, respectively, in the extractive system. Various important parameters for full color development have been investigated and the method has been successfully applied for the determination of the above-mentioned pesticides in various vegetable samples.

Abstract

Qualities of Indian gooseberry fruits ( Phyllanthus emblica L.) were determined after dip-treatment with wax emulsion (WE) with or without morphactin (Mor) and gibberellic acid (GA 3 ). Dip-treatments with 100–500 mg l −1 Mor reduced marketability by inducing browning and high weight loss, but loss in ascorbic acid was checked and phenols increased. 10 mg l −1 Mor maintained marketability at par with control, effectively controlled loss in ascorbic acid, and increased acidity and reducing sugars. GA 3 , although failing to control the loss of ascorbic acid, was effective in checking browning and thereby increased the market value of fruits as compared with controls and Mor-treated fruits. WE with or without Mor (10 mg l −1 ) controlled browning, accumulation of phenols and losses in weight and moisture as compared with 10 mg l −1 Mor, 100 mg l −1 GA 3 , or control, but could not retain ascorbic acid in comparison to 10 mg l −1 Mor-treated fruits. Marketability of fruits having had treatment with either WE or GA 3 was the same. Fruits having had combined treatment with WE and 10 mg l −1 Mor had maximum marketability. Minimum marketability was observed in fruits subjected to a combined treatment of WE + 100 mg l −1 GA 3 due to maximum infection with Aspergillus spp. and Penicillium spp.

Abstract

Twenty-two apple rootstocks were screened against Pythium ultimum Trow in the field. Six, including M2, M4, MM110, MM114, MM115 and Crab apple were highly resistant, 9 were resistant, 5 were susceptible and 2 (MM103 and MM104) were highly susceptible. In the field, maximum susceptibility of apple rootstocks was found during March (bud-swell stage) followed by July (maximum growth period) and minimum in November (leaf-fall stage). In the laboratory, these growth periods had no influence on the susceptibility of apple rootstocks and apple cultivars.

Abstract

Pleurotus florida colonisation on cold water-washed straw after spawning was at a higher rate than on the sieved or untreated straw. Washing increased the number of Pleurotus colonies present in the first 20 days and contaminant fungal colonies were absent. At the time of initiation of sporophere primoridia by day 27 the high NDF cell soluble content, minimum (15%) DM loss with maximum (44%) in vitro OM digestibility indicated that the available straw preparation was most suitable as animal feed. The results suggested that to reduce substrate OM loss an appropriate stage of growth of a specific fungus should be determined when employed for the nutritive upgrading of straw or other crop residue.

Abstract

The refrigeration efficiency, mass flows through IP and HP compressors, power input and inter-stage pressures at the optimum thermodynamic performance of three stage systems are presented graphically for the most common refrigerants, R 12, R 22 and R 717. Correlations are developed to account for the effects of subcoooing of condensate and super-heating of vapour in the evaporator, each up to 15 K. The effects of superheat up to 4 K for the vapours entering the IP and HP compressors on the system performance are also studied in order to simulate real systems more closely. The respective ranges of condensing and evaporating temperatures are taken as 273.15 to 333.15 K and 273.15 to 213.15 K, with T h − T 1 ⩾60 K.

Abstract

In naturally fermenting urea-straw in a non-turned stack with 60–70% moisture, a negligible mesophilic (MP) count with a high thermotolerant-thermophilic (TTP) population was observed after 9 days. The TTP microorganisms appeared to biodegrade lignin and synthesize protein. The straw cell wall constituents remained unchanged between days 9 and 12 of fermentation. Compared to the above, stacks with 40% and 50% moisture, due to low temperature, favoured higher MP microbial number at 40% and 50% moisture mainly ureolytic activity during 9 days. The above microbial population pattern was also noticed on day 28 when urea-straw with 45% moisture was stacked for ammonia treatment. The 28 days' stacking also resulted in the considerable OM loss with lignin content similar to that present on day 9 using 70% moisture. The available results showed that 28-day ammonia treatment with urea is a microbial process which can be completed in 9 days with minimum nutrient losses. However, for achieving lignin biodegradation and protein enrichment through TTP organisms, 70% moisture will favour the establishment of a desirable safe microbial population within 9 days of the natural fermentation of urea-straw.

Abstract

Batch and continuous wet grinding experiments were carried out in a 40 × 40 cm grate-discharge ball bill. Well-distributed −4 and −20 mesh feeds of two complex pyritic ores were used. The vol. % solids in the pulp ranged from 30 to 40, the particle load from 5 to 8 kg, and the solids feed rate from 70 to 110 kg/h. Analysis of the experimental data showed that over the range of operating conditions investigated, a linearized model could be used to predict the size distributions of both the mill product as well as the mill hold-up of the solids, very accurately. The breakage rate parameters, Si, were found to be dependent on the mode of operation, independent of the percent solids in the pulp, and approximately inversely proportional to the mill hold-up weight of the solids. In the case of the continuous mode of operation, with decrease in particle size the rate parameter values became increasingly smaller by comparison with the corresponding expected batch operation values.

Abstract

A new simple Spectrophotometric method for the determination of carbaryl in grains, pulses, and insecticide formulations is described. The method is based on the coupling of carbaryl with diazotized p-aminoacetophenone in a fairly alkaline medium to produce a dye having absorbance maxima at 545 nm. The dye thus formed is extractable in n-butanol. The extract has a maximum absorbance at 555 nm. Beer's law is obeyed in the range of 0.05–0.4 ppm of carbaryl. The method was found to be free from interferences of large amounts of phenol, 1-naphthol, and other carbamate insecticides such as propoxur. The method has been successfully applied to the determination of carbaryl residue in grains, pulses, and insecticide formulations.

Abstract

A multi-stage refrigeration-heat pump system to produce both cooling and heating for industrial applications is an interesting possibility. Such refrigeration-heat pump systems operating on working fluids R12, R22 and R717 have been optimized numerically. Optimum inter-stage temperatures, coefficients of performance, compression ratios, heating and cooling effects and refrigerant mass handled by high pressure compressor have been presented in tabular form for condensing temperatures of 20, 40 and 60°C, and evaporating temperatures of from 5 to −45°C in 5°C increments. Several graphs have been prepared to illustrate the feasible operating range for R12, R22 and R717 multi-stage refrigeration-heat pump systems. The design data presented can be used for the preliminary optimum design of multi-stage refrigeration-heat pump systems operating on R12, R22 and R717.

Abstract

Urea and wheat straw moistened to 70% was stacked in the open for 12 or 9 days' natural fermentation. The urea was added at the rate of 4% on a dry straw basis. The fermentation was carried out by turning the stacks at 3- or 6-day intervals, or the stacks were not turned for the entire periods. About 84% to 87% was degraded during the fermentation, resulting in microbial-protein enrichment of the treated straw. A high stack temperature developed (65°C to 73°C) and the ammonia released penetrated the cell wall sufficiently to loosen the ligno-cellulose bonds. The microbes utilized hemicellulose and cellulose, without effecting the lignin content. The daily dry matter intake (7·96kg) during a 4-month acceptability trial, using 12 day fermented straw with 2·0 kg fresh green fodder and minerals, showed the straw was palatable and was able to maintain the six adult buffaloes without affecting their body weight or health. Further metabolic trials with the different straw preparations showed that digestibilities of DM, OM, CF and cellulose, and N retention, were significantly (P < 0·01) improved in 9 day fermented straw as compared with the other straw preparations. The results showed that, by 9 days' fermentation of wheat straw, the cellulose digestibility and apparent biological value were improved to the extent that fermented straw supplemented with adequate vitamins and minerals could be used as a sole maintenance ration for ruminants.

Abstract

Simple graphical procedures for determination of empirical correlations for the variations in selection parameters of the discretized batch grinding equation with the particulate mass and the size of the grinding media balls are described. The influence of the particulate mass is given by a single correlation function which is valid for all particle size intervals, as well as both starved and saturated mill loadings. The search for the correlation for the effect of ball size can be considerably simplified by plotting the data in a particular fashion which results in a self-preserving curve, independent of the particle size.

Abstract

For dry ball mill grinding operation, the effect of ball and mill diameters on grinding rate parameters of the size-discretized population balance model has been investigated for quartz, limestone, a soft cement clinker and a hard cement clinker. Experiments were performed in three mills of 29.2, 40.6 and 61.0 cm diameter. The diameter of the balls used ranged from 1.27 to 3.81 cm. The particle size range covered was 8 10 to 100 150 mesh. The rate parameter values were determined very accurately using a special technique. It has been shown that the particle size exponent α in equation Si = Axiα is independent of ball and mill diameters. Based on this fact, a new correlation has been developed to describe the effect of ball and mill diameters on the rate parameters. The various constants in this correlation are strongly material dependent.

In a Typic Torripsamments (loamy sand) soil, 4 levels each of Cu and Mo,viz, 0, 5, 10 and 20; and 0, 0.5, 1.0 and 2.0 ppm, respectively, were added to study Cu−Mo relationship in cowpeas in a screen-house. Application of Mo reduced Cu content andvice versa in leaves, stems and roots of cowpeas. Stems accumulated more of Mo and Cu than leaves and roots, showing thereby, that it might be the site of interaction for Mo and Cu. Molybdenum increased to a toxic level in plant (for animals) following its application. Cu/Mo ratio was narrowed with Mo and widened with Cu addition. It was either more than 2∶1 or less which suggested that Mo would cause Cu deficiency and Cu in the absence of Mo would be toxic to ruminants.

Abstract

Post-harvest application of wax emulsion, with or without morphactin (2.5–10.0 mg l−1, has been applied to prolong the shelf-life of pods of okra (Abelmoschus esculentus L. Moench) of different maturities. Post-harvest application of 10.0 mg l−1 morphactin + wax emulsion induced significantly higher losses, in weight, moisture, chlorophylls, sugars (reducing and non-reducing) and starch after the storage period at room temperature, than 2.5 or 5.0 mg l−1 morphactin + wax emulsion. The lower morphactin concentrations with wax emulsion were effective to control the above mentioned changes in long pods, while only 2.5 mg l−1 morphactin with wax emulsion was found to be effective in controlling them in smaller pods, thereby enhancing the shelf-life of okra pods of different maturities. The results suggest that wax emulsion with 2.5 mg l−1 morphactin can be applied commercially as a new means to prolong the shelf-life of okra pods.
