A study was conducted to provide practical guidance for synthetic chemists on the synthesis of oxygen-, nitrogen-, and sulfur-containing heterocyclic rings. Reaction of benz(g)indole dicarboxylate 5 with hydrazine hydrate in refluxing ethanol and a catalytic amount of pyridine chemoselectively produced only 63% of benz(g)indole monocarbohydrazide 7 instead of the expected dicarbohydrazide 6 wherein the C3carboethoxy group remained unchanged toward nucleophile hydrazine hydrate. The resistance of the heterocycles formed, starting with five- and six-membered rings. These systematic collections in the study expanded the ample possibilities to the synthetic methods accessed by the chemistry for synthesis of heterocyclic compounds and would be useful to pick the route for further research.

This paper describes the development of multiphase hybrid composites consisting of epoxy reinforced with glass-fiber and filled with rice husk particulates. It further investigates the mechanical properties and erosion wear response of these composites and presents a comparison between the unfilled and filled samples. The erosion wear experiments are conducted as per design of experiment approach using Taguchi's orthogonal arrays. The Taguchi approach enables us to determine optimal parameter settings that lead to minimization of the erosion rate. The results indicate that impact velocity, filler content, impingement angle and erodent size influence the wear rate significantly. The experimental results are in good agreement with values from the mathematical and artificial neural network (ANN) model. The objective of the present work is to fabricate a new class of epoxy based low cost hybrid composites reinforced with glass fiber and filled with rice husk powder in different weight proportions and to study the mechanical and erosion wear performance of these composites. This study reveals that hardness, tensile modulus, impact energy and erosion resistance of these new class hybrid composites are improving with filler addition while a steady decline in tensile and flexural properties are observed. © 2012 Elsevier Ltd.

The formation of well-ordered nanostructures through self-assembly of diverse organic and inorganic building blocks has drawn much attention owing to their potential applications in biology and chemistry. Among all organic building blocks, peptides are one of the most promising platforms due to their biocompatibility, chemical diversity, and resemblance to proteins. Inspired by the protein assembly in biological systems, various self-assembled peptide structures have been constructed using several amino acids and sequences. This review focuses on this emerging area, the recent advances in peptide self-assembly, and formation of different nanostructures, such as tubular structures, fibers, vesicles, and spherical and rod-coil structures. While different peptide nanostructures have been discovered, potential applications are explored in drug delivery, tissue engineering, wound healing, and surfactants.

Purpose-This study aims to focus on the keenness of students of business schools of Orissa (India) on the use of electronic resources and attempts to evaluate the level of electronic information services offered by the primary information reserves of the respective business schools with an opinion pool of sample respondents. Moreover, it intends to elicit the barriers in use of e-information with recommendations for the improvement of services and usage of e-resources. Design/methodology/approach-The paper examines the use of electronic resources by students of business schools of Orissa (India) through structured questionnaires. SPSS is used for data analysis. Findings-The study finds that students express keen interest in the use of e-journals, followed by e-books, e-newspapers, e-reports, and e-articles. Least interest is shown towards the use of electronic theses and dissertations. The study reveals that the majority of students are aware of EBSCO, and Emerald Management Xtra. However, the awareness of all other databases is not quite so encouraging. Further, it is revealed that the use of printed materials is slightly more compared to that of e-resources. Use of Web OPAC is also less than expected. Practical implications-The paper highlights the practicality of the use of electronic resources, compared to print, among the students of business schools of Orissa (India). Originality/value-The paper reveals the degree of use of electronic resources by business students and makes some useful deductions for its subsequent generalization. © 2010 Emerald Group Publishing Limited.

Tribology in Industry | Year: 2013

A four stroke four cylinder in-line petrol engine is modeled to estimate various performance parameters. The solution is based on tribology and dynamics principle. The detailed parameters related to engine friction and lubrication are computed numerically for the 1-3-4-2 engine firing order. The numerical method is based on finite difference method that solves coupled Reynolds Equation and Energy equation. Output includes the film thickness, friction force, friction power loss and temperature rise in ring liner conjunction in all four cylinders. Transient regime of ring liner lubrication is addressed while the same changes from hydrodynamic to mixed in an engine cycle. Momentary cessation near top and bottom dead center that causes boundary interaction is analyzed through asperity contact. The non- Newtonian behavior of lubricant due to film pressure and temperature is addresses using viscosity-pressure-temperature inter relationship. © 2013 Published by Faculty of Engineering.

Performance characteristics of a rough elliptic bore journal bearing are studied. The bearing bore of isotropic roughness orientation is characterized by stochastic function and the film geometry is quantified to elliptic shape. There after the Reynolds equation and energy equation are descretized for pressure and temperature respectively. A finite difference model is developed to evaluate hydrodynamic pressure and oil temperature. Solution to this model is done using effective influence Newton-Raphson method. Performance parameters such as load bearing ability, friction, flow-in and side leakages are computed and discussed. © 2014 Published by Faculty of Engineering.

The present work deals with some machinability studies on flank wear, surface roughness, chip morphology and cutting forces in finish hard turning of AISI 4340 steel using uncoated and multilayer TiN and ZrCN coated carbide inserts at higher cutting speed range. The process has also been justified economically for its effective application in hard turning. Experimental results revealed that multilayer TiN/TiCN/Al 2O 3/TiN coated insert performed better than uncoated and TiN/TiCN/Al 2O 3/ZrCN coated carbide insert being steady growth of flank wear and surface roughness. The tool life for TiN and ZrCN coated carbide inserts was found to be approximately 19 min and 8 min at the extreme cutting conditions tested. Uncoated carbide insert used to cut hardened steel fractured prematurely. Abrasion, chipping and catastrophic failure are the principal wear mechanisms observed during machining. The turning forces (cutting force, thrust force and feed force) are observed to be lower using multilayer coated carbide insert in hard turning compared to uncoated carbide insert. From 1st and 2nd order regression model, 2nd order model explains about 98.3% and 86.3% of the variability of responses (flank wear and surface roughness) in predicting new observations compared to 1st order model and indicates the better fitting of the model with the data for multilayer TiN coated carbide insert. For ZrCN coated carbide insert, 2nd order flank wear model fits well compared to surface roughness model as observed from ANOVA study. The savings in machining costs using multilayer TiN coated insert is 93.4% compared to uncoated carbide and 40% to ZrCN coated carbide inserts respectively in hard machining taking flank wear criteria of 0.3 mm. This shows the economical feasibility of utilizing multilayer TiN coated carbide insert in finish hard turning. © 2012 Elsevier Ltd. All rights reserved.

Piston compression ring and cylinder liner contact contributes a significant part of friction loss in an engine. Most of this loss occurs during compression and power stroke transition (i.e., between 300 to 400 crank position). It is because of the combustion gas pressure is higher in this region to enhance ring-liner contact friction. In this paper, we developed a tribodynamic model to study the transient thermoelastohydrodynamics of ring-liner contact. It takes into account the combined solution of Reynolds equation, energy equation, and elastic deformation equation considering ring-liner conformability and rheology change. We estimate the minimum film profile, friction force, and friction power loss within a high-pressure zone of a high-performance engine. Roughness of the liner is characterized using R k parameter for better surface representation. © 2012 Springer-Verlag London Limited.

The objective of the study is to assess the performance of multilayer coated carbide insert in the machining of hardened AISI D2 steel (53 HRC) using Taguchi design of experiment. The experiment was designed based on Taguchi L27 orthogonal array to predict surface roughness. The S/N ratio and optimum parametric condition are analysed. The analysis of variance has also been carried out to predict the significant factors affecting surface roughness. Based on Taguchi S/N ratio and ANOVA, feed is the most influencing parameter for surface roughness followed by cutting speed whereas depth of cut has least significant from the experiments. In regression model, the value of R2 being 0.98 indicates that 98 % of the total variations are explained by the model. It indicates that the developed model can be effectively used to predict the surface roughness on the machining of D2 steel with 95% confidence intervals. © 2014 Growing Science Ltd.

Expression levels of genes vary not only between different environmental conditions ("plasticity") but also between genetically identical cells in constant environment ("noise"). Intriguingly, these two measures of gene expression variability correlate positively with each other in yeast. This coupling was found to be particularly strong for genes with specific promoter architecture (TATA box and high nucleosome occupancy) but weak for genes in which high noise may be detrimental (e.g., essential genes), suggesting that noise-plasticity coupling is an evolvable trait in yeast and may constrain evolution of gene expression and promoter usage. Recently, similar genome-wide data on noise and plasticity have become available for Escherichia coli, providing the opportunity to study noise-plasticity correlation and its mechanism in a prokaryote, which follows a fundamentally different mode of transcription regulation than a eukaryote such as yeast. Using these data, I found significant positive correlation between noise and plasticity in E. coli. Furthermore, this coupling was highly influenced by the following: level of expression; essentiality and dosage sensitivity of genes; regulation by specific nucleoid-associated proteins, transcription factors, and sigma factors; and involvement in stress response. Many of these features are analogous to those found to influence noise-plasticity coupling in yeast. These results not only show the generality of noise-plasticity coupling across phylogenetically distant organisms but also suggest that its mechanism may be similar. © 2013 Singh.
