Powder metallurgy: Advanced techniques and applications

In this paper, a brief review about the advancement in powder metallurgy process along with their applications as well as problems faced during the research is discussed. The main objective of this paper is to accentuate the applications of advanced powder metallurgy technology in various fields and also to encourage the readers to understand and write more papers on such issues. Advanced Powder Metallurgy is also known as metal injection moulding (MIM) technology helpful for forging complex shaped components with low investment of money. Therefore, a forming technology applied to form new materials by diffusion of different metals as well as ceramic powders as raw ingredients through sintering (temperature below melting point) is known as powder metallurgy. The most advantageous thing of this process is that, the powder can easily be shaped directly into the end product and also possesses significant degree of freedom in the composition of materials, properties, microstructure and thermal processing. Powder Metallurgy provides such properties that cannot be achieved by melting process. Advancement in Powder Metallurgy technique is a standard allusion for the engineers in the metal forming industries that use powder metallurgy with a research interest in the field.

Analytical method development of Flonicamid by R – HPLC

A simple reverse phase liquid chromatographic method has been developed and subsequently validated for the Flonicamid are a fungicide molecule; which is applicable for the treatment of the vegetable and fruits fungal decease. These Flonicamid molecules were separated through a mobile phase consisting of the mixture of acetonitrile, methanol, and water in the ration of 10:30:60. All these solvents are HPLC grade. Column: Qualis BDS C18 (250 x 4, 5μ); Flow rate: 1.0 ml/min; Detector: UV-Vis. Absorption (λ) at 230 nm of Shimadzu HPLC (model: LC-2030). The LC solution software was used for the analytical method, data integrations, and calculations in this analysis. There are two molecules were analyzed for separation and quantification. The results of the study showed that the proposed RP-HPLC method is simple, rapid, precise and accurate, which is useful for the identification and quantifications of these molecules interims of validation parameters viz., separation, system suitability, System Precision and linearity in a simple HPLC analysis.

Comparative study of various seismic analysis methods for RC structure

A large number of RC frame buildings have been built in India in recent years. A huge number of similarly designed and constructed buildings exist in the various towns and cities situated in moderate to severe seismic zones of the country. Analysis and design of such buildings for static forces is a routine affair these days because of availability of affordable computers and specialized programs which can be used for the analysis. On the other hand, dynamic analysis is a time-consuming process and requires additional input related to the mass of the structure, and an understanding of structural dynamics for interpretation of analytical results. Reinforced Concrete (RC) frame buildings are the most common type of constructions in urban India, which are subjected to several types of forces during their lifetime, such as static forces due to dead and live loads and dynamic forces due to the earthquake. To ensure safety against seismic forces of multi-storied building hence, there is need to study seismic analysis to design earthquake resistance structures. In the present study, a multi-storied framed structure is selected, And Linear seismic analysis is done for the building by a static method (Equivalent Static Method) and dynamic method (Response Spectrum Method & Time history Method) using ETAB2016 as per the IS-1893-2002-Part-1. As a result, the response of structure has been obtained for considered building models, based on each method of analysis, and then the results are compared with each other.

Effects of country of origin on the relationship of service quality expectations and choice of banking brands

The service sector is highly impacted by the fourth industrial revolution. Technology is the backbone of most services today. Technology is blurring the characteristics of services like inseparability, perishability and for sure variability. Banking a most often transacted service is no different. The relationship of service quality expectations with choice of brand is well established, but in a highly competitive environment where general service quality attributes are almost non-variable, it becomes important to understand what other constructs influence the service brand choices. We in this paper attempted to explore how the country of origin influences the choice of service brands. Paper attempts to validate if the country of origin which is so predominant in goods, influences the brand choice for services. The empirical study was initiated with a survey conducted on convenient sample across India, country of origin of two pre-tested banks having most mindshare, one a private player another a foreign bank operating in India and lastly the choice of brands amongst the two. The respondents had to rate both the banks, private and foreign so that the perceptions can be dissected. We noticed through the descriptive study that while assurance and trust continue to weigh high as quality dimensions for most respondents. It is also observed that people make a choice primarily because of “Empathy” dimension of SERVQUAL. The study also revealed that there is a significant relationship between service quality expectations (SQE) and country of origin (COO) which is well moderated by age. The study has also revealed (COO) influences service expectations and choice of service brands.

Worker safety skill training – Foundation for a sustainable safe workplace

This study focuses on the importance of safety at workplace and OHS (Occupational Health & Safety) practices. It discusses the rationale behind why worker safety training is important for a safety management system, the existing challenges and the possible solutions and action points to overcome them. It also discusses the different means of people engagement in safety management both at a conceptual level as well as its actual implementation. Various facets of safe work culture have been examined through data analysis of nine elements of the Job Satisfaction Survey (JSS) which shows an interesting result. It depicts that supervision satisfaction and present work satisfaction of the workers have a direct correlation with the safety performance. The purpose is to empower the base of the pyramid where workers are exposed to real hazards.

Hand gripper design as an application of EMG measurement

The medical, rehabilitation and bio-mimetic technology demand human actuated devices which can support in the daily life activities such as functional assistance or functional substitution of human organs. These devices can be used in the form of prosthetic, skeletal and artificial muscles devices. Such devices are costly which is not affordable to every consumer so to overcome these we have designed a hand gripper which uses the electromyography (EMG)signals to control this device.
