Tragic Aspects in Arthur Miller’s Plays

In this research paper an attempt has been made to show ‘Tragic aspects in Arthur Miller’s plays’. Tragedy has always been a prominent genre in drama around the world. In fact, to the ancient Greeks, tragedy is a genre so significant that it is associated with religious practices and the religious concept of purification. Arthur Miller (1915-2005) is considered one of the foremost American playwrights of the twentieth century who wrote a remarkable series of highly regarded pieces that reveal profound insight, humanism and empathy that are the hallmarks of his great dramatic works. Miller has his own concept of tragedy as a modern playwright. He believes that tragedy may depict ordinary people in domestic surroundings instead of talking about a character from a high rank, a king or queen. Miller’s main concern lies in dramatizing the whole man as he is part of a family and as he is part of a society. This research thus aims to explore the development of the tragic hero between Aristotle and Miller

Rooftop Solar Photovoltaic for CSIR-NPL at New Delhi: A Case Study

Solar energy is an abundant and renewable energy source and the annual solar energy incident at the ground in India is about 20,000 times the current electrical energy consumption. The use of solar energy in India has been very limited. The average daily solar energy incident in India is 5 kWh/m2 days, which can be utilize in electricity generation. There are many solar installations are already operational in India, however, due to the inefficient solar panels and their geometry limited the efficiency in terms of conversion of sunlight in to high unit power generation. In the current work, reduced the need of land to install the solar panel in the small area rather than existing larger area and increase solar panel efficiency in term of unit generation. A case study has been carried out by taking various kinds of panels (static and rotation/tracking) and 15 to 18% efficiency for static panel and 40 to 45% for tracking panel. This enhancement in efficiency was mainly due to the design and developed tracking solar panel with Light Dependent Resistors

Terahertz Detectors (THzDs): Bridging the Gap for Energy Harvesting

It is indispensable to integrate electronics with environment for better lives. Huge amount of solar energy, dark energy, and unused microwave energy is untapped till now due to insufficient availability of high frequency THz detectors. The difference between THz wave detection and THz electric field detection must be clear. THz wave detection connects the detection of explosives, drugs, astronomy, metals, and imaging applications, etc. On the other hand, THz electric field detection involves the conversion of electromagnetic (EM) radiations to usable DC power. The optimum choice of detectors for energy harvesting is a highly diverse area. The latter part is concentrated on the nonlinear behavior of the incoming radiations and has been highlighted also. In this chapter, metal‐insulator‐metal (MIM) diode detectors have been explored to become a best choice for high frequency detectors

Effect of cadmium on glycogen content in muscle, liver, gill and kidney tissues of freshwater fish Channa punctatus (Bloch)

Aquatic environment gets polluted by heavy metals because of their environmental persistence and ability to bioaccumulate in aquatic organisms. Cadmium is a ubiquitous toxic heavy metal, biologically non-essential element, it is not biodegradable and has a very long biological half-life. The aim of the present study was to assess the glycogen content in muscle, liver,  gill and kidney of Channa punctatus exposed to sublethal concentrations of cadmium chloride after 4, 7, 15 and 30 days of exposure. The results clearly showed significant decrease in the glycogen levels in the experimental fish C. punctatus. Decrease in muscle glycogen was found highly significant (P<0.001) after 30 days in both low concentration (36.823 mg/L) 6.12±0.41mg/g and in high concentration (73.646 mg/L) 4.04±0.32 mg/g in comparison to control. Decrease in liver glycogen content was found highly significant (P<0.001) after 30 days in high concentration 9.12±0.49 mg/g when compared with control. The decrease in gill glycogen content after 30 days exposure was found highly significant (P<0.001) 1.36±0.13 mg/g in low concentration and in high concentration 0.79±0.25 mg/g in comparison to control. Decrease in kidney glycogen content was found highly significant (P< 0.001) at 30 days in low concentration 3.92±0.05 mg/g  and in high concentration 2.81±0.20 mg/g  in comparison to control. The influence of toxicant cadmium chloride in selected tissues of fish was taken into account in evaluating fish response against stressor. Hence, we can use glycogen content as biomarker of cadmium stress in fish

A NUTRITIONAL STUDY OF TRIBAL AND NON-TRIBAL CHILDREN IN THE UDAIPUR REGION

Objective: There is an evidence that nutrition has a significant impact on children’s development, adult health, and senescence. It is also known to have an impact on one’s physical and mental faculties. Malnutrition is now understood to be the root cause of a significant variety of health issues. To compare the nutritional condition of 300 (tribal and nontribal) children living in the Udaipur region, a dietary survey was conducted. Methods: In the present study, 300 tribal and non-tribal children between the ages of 1 and 12 were chosen for a dietary survey to evaluate their nutritional status. The survey was conducted using a questionnaire. Results and Conclusion: The statistics between tribal and non-tribal children showed that calorie, protein, fat, and carbohydrate intake was lower in the tribal children. When we compared the data between tribal and non-tribal children, we found that the non-tribal children’s calorie, protein, fat, and carbohydrate intake was not superior. Ascorbic acid and B-carotene intake among non-tribals is also less than that advised by the ICMR and is approximately twice as low as that among their tribal counterparts. The statistics on tribal and non-tribal children made it abundantly evident that nutritional intake is low that consumption of fat among dense nutrients is significantly lower and that intake of antioxidant nutrients such as ascorbic acid and beta-carotene is similarly poor

Electronic Resources of Libraries of First-Generation Indian Institute of Management (IIM): An Evaluative Analysis

As an essential component and one of the quality assessment measures, the availability of electronic resources is gaining significance in libraries, hence increasingly becoming part of the acquisition and collection-building activities. Libraries and information centres play a pivotal role in selecting, acquiring and providing effective access to electronic resources to its users under various categories to meet their academic and scholarly requirements. This paper analyses the availability and distribution of electronic resources among the selected libraries of the Indian Institute of Management (IIMs) in India. Researchers have chosen six IIMs identified as first-generation libraries for analysing the holding of e-resources as part of its library services. The study compares various dimensions of electronic resources such as availability of different types of resources, its source of availability, mode of access and the customized services through specialized tools and collaborative networks. Researchers observed from the analysis that all the first-generation IIM libraries are part of IIM library consortia and are the major source of electronic resources rather than individual subscriptions and the majority of the libraries are providing customized services through specialized access tools. The findings and suggestions incorporated in this study may be useful for the library professionals and the administrators associated with the IIM libraries to further improve the management of their electronic resources

A facile approach to fabricate graphene based piezoresistive strain sensor on paper substrate

Sensors, FETs and chemi resistors are few of the devices which show potential in the area of flexible electronics for health monitoring applications. In the present work, piezoresistive strain sensors based on graphite and graphene on cellulose paper substrate has been reported. Graphite sensor has been fabricated by rubbing pencil on paper and graphene sensor by directly coating graphene ink using paint brush. The resistance of the fabricated sensor increases with outwards bending and vice-versa, further the piezoresistive effect has also been evaluated by applying variable longitudinal stress. A comparative study of gauge factor (GF) depending upon different type of strains has been presented and it has been observed that the GF of graphene piezoresistive strain sensor decreases with increase in number of layers, the GF for graphene sensor is higher as compared to graphite sensor. Fabricated piezoresistive strain sensors may find applications as human body motion detection, gait analysis etc

Kinetic and mechanistic study of oxidation of 1,2-propanediol by aqueous alkaline solution of N-bromosuccinimide in the presence of aquachloro-complex of ruthenium(III) as homogeneous catalyst

Kinetics of Ru(III) catalysis in oxidation of 1,2-propanediol by N-bromosuccinimide in alkaline media has been studied in presence of mercuric acetate as bromide ions scavenger in the temperature range of 30–45 °C. The reaction follows complex kinetics, being first order with respect to both 1,2-propanediol and Ru(III). First order kinetics with respect to NBS at its lower concentrations shifts to zero order at its high concentrations. Variation of both [OH-] and [KCl] shows a positive effect on the rate of reaction. Negligible effect of addition of succinimide (reduction product of NBS) is observed, while variation of both [Hg(OAc)2] and ionic strength has no effect on rate of the reactions. Various activation parameters are calculated. The products of the reactions have been identified as acetic acid and formic acid. A suitable mechanism in conformity with the kinetic observations is discussed and rate law derived

Mycobacterium tuberculosis NAD(+)-dependent DNA ligase is selectively inhibited by glycosylamines compared with human DNA ligase I

DNA ligases are important enzymes which catalyze the joining of nicks between adjacent bases of double-stranded DNA. NAD(+)-dependent DNA ligases (LigA) are essential in bacteria and are absent in humans. They have therefore been identified as novel, validated and attractive drug targets. Using virtual screening against an in-house database of compounds and our recently determined crystal structure of the NAD(+) binding domain of the Mycobacterium tuberculosis LigA, we have identified N(1), N(n)-bis-(5-deoxy-α-d-xylofuranosylated) diamines as a novel class of inhibitors for this enzyme. Assays involving M.tuberculosis LigA, T4 ligase and human DNA ligase I show that these compounds specifically inhibit LigA from M.tuberculosis. In vitro kinetic and inhibition assays demonstrate that the compounds compete with NAD(+) for binding and inhibit enzyme activity with IC(50) values in the µM range. Docking studies rationalize the observed specificities and show that among several glycofuranosylated diamines, bis xylofuranosylated diamines with aminoalkyl and 1, 3-phenylene carbamoyl spacers mimic the binding modes of NAD(+) with the enzyme. Assays involving LigA-deficient bacterial strains show that in vivo inhibition of ligase by the compounds causes the observed antibacterial activities. They also demonstrate that the compounds exhibit in vivo specificity for LigA over ATP-dependent ligase. This class of inhibitors holds out the promise of rational development of new anti-tubercular agents
