Authors: Janani V., Tanika Singh, Bala Subramanian R., Santosh Kumar Sharma
Abstract:
Higher education across the globe is undergoing a sea change. This has created a varied management of higher education in Indian universities, and therefore, we find no universal law regarding HR policies and practices in these universities. As a result, faculty retention is very low, which is a serious concern for educational leaders such as vice-chancellors or directors working in the higher education sector. We can understand this phenomenon in the light of various management theories, among which theory z proposed by William Ouchi is a prominent one. With this backdrop, the present article strives to contextualize theory z in Indian higher education. For the said purpose, qualitative methodology has been adopted, and accordingly, propositions have been generated. We believe that this article will motivate other researchers to empirically test the generated propositions and thereby contribute in the existing literature.Keywords: education, managemenet, motivation, Theory X, Theory Y, Theory Z, faculty members, universities, India

Authors: Neera Singh, Devendra Kumar, Om Parkash
Abstract:
We have synthesized nanocrystalline Fe-Ni alloy powders where Ni varies as 10, 30 and 50 mole% by a wet chemical route (sol-gel auto-combustion) followed by reduction in hydrogen atmosphere. The ratio of citrate to nitrate was maintained at 0.3 where citric acid has worked as a fuel during combustion. The reduction of combusted powders was done at 700°C/1h in hydrogen atmosphere using an atmosphere controlled quartz tube furnace. Phase and microstructure analysis has shown the formation of α-(Fe,Ni) and γ-(Fe,Ni) phases after reduction. An increase in Ni concentration resulted in more γ-(Fe,Ni) formation where complete γ-(Fe,Ni) formation was achieved at 50 mole% Ni concentration. Formation of particles below 50 nm size range was confirmed using Scherrer’s formula and Transmission Electron Microscope. The work is aimed at the effect of Ni concentration on phase, microstructure and magnetic properties of synthesized alloy powders.Keywords: combustion, microstructure, nanocrystalline, reduction

Authors: Bijaya Kumar Sahoo
Abstract:
The effect of III-V nitride semiconductors on performance of a graphene-on-gold surface plasmon resonance (SPR) biosensor has been investigated theoretically. III-V nitrides (AlN, GaN and InN) have been grown between gold (Au) and graphene layers. The sensitivity and performance of the biosensor have been computed for with and without semiconductors. Due to superior electronic and optical properties, III-V nitrides demonstrate high sensitivity and performance over Si and Ge. The enhancement of evanescent electric field due to III-V nitrides have been computed and found highest for InN. The analysis shows that for a high-sensitive imaging biosensor the required optimal thickness of gold, InN and graphene are respectively 49 nm, 11 nm and 0.34 nm for the light of wavelength =633 nm (red He-Ne laser). This study suggests that InN would be a better choice for fabrication of new imaging SPR biosensors.Keywords: SPR biosensor, optical properties, III-V nitrides, sensitivity, enhancement of electric field, performance of graphene gold SPR biosensor

Authors: B. T. Naveen Kumar, Anuj Tyagi, Niraj Kumar Singh, Visanu Boonyawiwat, A. H. Shanthanagouda, Orawan Boodde, K. M. Shankar, Prakash Patil, Shubhkaramjeet Kaur
Abstract:
Early mortality syndrome (EMS)/Acute Hepatopancreatic Necrosis Disease (AHPND) has emerged as a major obstacle for the shrimp farming around the world. It is caused by a strain of Vibrio parahaemolyticus. The possible preventive and control measure is, early and rapid detection of the pathogen in the broodstock, post-larvae and monitoring the shrimp during the culture period. Polymerase chain reaction (PCR) based early detection methods are good, but they are costly, time taking and requires a sophisticated laboratory. The present study was conducted to develop a simple, sensitive and rapid diagnostic farmer level kit for the reliable detection of AHPND in shrimp. A panel of monoclonal antibodies (MAbs) were raised against the recombinant Pir B protein (rPirB). First, an immunodot was developed by using MAbs G3B8 and Mab G3H2 which showed specific reactivity to purified r-PirB protein with no cross-reactivity to other shrimp bacterial pathogens (AHPND free Vibrio parahaemolyticus (Indian strains), V. anguillarum, WSSV, Aeromonas hydrophila, and Aphanomyces invadans). Immunodot developed using Mab G3B8 is more sensitive than that with the Mab G3H2. However, immunodot takes almost 2.5 hours to complete with several hands-on steps. Therefore, the flow-through assay (FTA) was developed by using a plastic cassette containing the nitrocellulose membrane with absorbing pads below. The sample was dotted in the test zone on the nitrocellulose membrane followed by continuos addition of five solutions in the order of i) blocking buffer (BSA) ii) primary antibody (MAb) iii) washing Solution iv) secondary antibody and v) chromogen substrate (TMB) clear purple dots against a white background were considered as positive reactions. The FTA developed using MAbG3B8 is more sensitive than that with MAb G3H2. In FTA the two MAbs showed specific reactivity to purified r-PirB protein and not to other shrimp bacterial pathogens. The FTA is simple to farmer/field level, sensitive and rapid requiring only 8-10 min for completion. Tests can be developed to kits, which will be ideal for use in biosecurity, for the first line of screening (at the port or pond site) and during monitoring and surveillance programmes overall for the good management practices to reduce the risk of the disease.Keywords: acute hepatopancreatic necrosis disease, AHPND, flow-through assay, FTA, farmer level, immunodot, pond site, shrimp
Procedia PDF Downloads 1541316 GPS Refinement in Cities Using Statistical Approach
Authors: Ashwani Kumar
Abstract:
GPS plays an important role in everyday life for safe and convenient transportation. While pedestrians use hand held devices to know their position in a city, vehicles in intelligent transport systems use relatively sophisticated GPS receivers for estimating their current position. However, in urban areas where the GPS satellites are occluded by tall buildings, trees and reflections of GPS signals from nearby vehicles, GPS position estimation becomes poor. In this work, an exhaustive GPS data is collected at a single point in urban area under different times of day and under dynamic environmental conditions. The data is analyzed and statistical refinement methods are used to obtain optimal position estimate among all the measured positions. The results obtained are compared with publically available datasets and obtained position estimation refinement results are promising.Keywords: global positioning system, statistical approach, intelligent transport systems, least squares estimation

Authors: Butchi Kameswara Rao Chittem, Rooban Kumar
Abstract:
Cement concrete is a complex mixture of different materials. Concrete is believed to have a good fire resistance. Behaviour of concrete depends on its mix proportions and its constituent materials when it is subjected to elevated temperatures. Loss in compressive strength, loss in weight or mass, change in colour and spall of concrete are reported in literature as effects of elevated temperature on concrete. In this paper results are reported on the behaviour of normal strength concrete and high strength concrete subjected to temperatures 200°C, 400°C, 600°C, and 800°C and different cooling regimes viz. air cooling, water quenching. Rebound hammer test was also conducted to study the changes in surface hardness of concrete specimens subjected to elevated temperatures.Keywords: normal strength concrete, high-strength concrete, temperature, NDT

Authors: Danish Gadda
Abstract:
Kashmir has been a bleeding-spot in the South Asian politics since 1947 when the subcontinent was bifurcated into Hindu, India and Muslim Pakistan by the departing British colonisers. Kashmir couldn’t accede to either of the two new-born, sovereign nations until tribal invasion from Pakistan forced an unfortunate change of events. India, driven by conditional accession signed by the Kashmir’s last monarch, sent its army to defend Kashmir Valley, with a promise, made subsequently, that the region’s fate would be decided by the natives through an internationally-monitored plebiscite. The country, however, broke its promise, choosing not to withdraw its military to allow the plebiscite, and, instead, strengthened its claim over Kashmir, which it later started describing as her integral part. War, fought in the shape of three and a half bloody battles, ensued between India and Pakistan, even as the United Nations’ intervention managed a ceasefire as early as in the 1950s, though not before Kashmir had come to be divided into its India-controlled and Pakistan-controlled halves. Prolonged, the dispute over Kashmir took a violent turn in 1989-90 with the start of an anti-India armed rebellion. Kashmiris have been fighting for their right to self-determination, and bringing their own life to a grinding halt has been one of their preferred forms of protest against the Indian rule. This form of resistance is locally called ‘Hartals’, and recognised as shutdowns, which have often been prolonged and violent. Since 1989-90, the shutdowns have become only more frequent and forceful, and there are marked days on which Kashmir shuts down in protest every year, like a ritual. This paper is based on a study of how the Indian and Kashmir press covered the shutdowns observed in the troubled valley on four such days: January 26 (Indian Republic Day), February 11 (the day on which India executed a prominent Kashmiri resistance leader), August 15 (India’s Independence Day), and October 27 (the day on which the Indian military has landed in Kashmir). The coverage given by the Indian and Kashmiri press to the shutdowns observed on these days has been studied using the multi-tier content analysis approach: 1) Difference in the number of shutdowns covered by the two section is looked at, 2) the placement of the stories in the two section of the press is analysed, 3) the discourse highlighted by the two section of the press is compared, and 4) the editorials written by the two section of the press about the shutdowns are analysed. The findings show the Indian and the local press have been focussing on the two, predictable extremes of the situation: the Indian press has favoured the state, while the Kashmir or the local press has focussed on the narrative opposing the state’s. The difference is noticed in the quantitative as well as the qualitative aspects of their coverage.Keywords: Indo-Pak tension, Kashmir conflict, protest shutdowns, South-Asian politics

Authors: Elaheh Ghasempour
Abstract:
India has always been an all-encompassing center of attention in the theological and cultural studies since it beholds a very diverse nation within its borders. Among the uncountable faiths and traditions of this massive land, this article shall negotiate Islam in a Hindu dominated society. Practicing Caste and the views on it are the most controversial topics in modern-day India. Some blame it on the teachings of Hinduism; some call it a colonial outcome; and yet many believe that it is, in fact, a social construct. Islam was the souvenir coming from the Arabian Peninsula into the Indian Subcontinent in the hands of Arab, Persian, and Turk religious missionaries and Sufi saints. The aim of bringing the faith to this region was to enlighten the people of East and the Far East with the ideas of peace, justice, brotherhood as well as a proper way of living. Due to many reasons, the concept of the Islamic Nation or ‘Ummah’ has been touched by the native teachings of Hinduism which negates and questions the actual Islamic principles and laws. The Islamic Nation in India has been parted to different classes and each class nowadays beholds one level of a hierarchy. The superiors do not hesitate to keep the inferiors oppressed as much as they can since their own high position in this hierarchy depends on such oppressions. Their rules and laws to keep the lower castes out of the political and economical scene found ways into the religious traditions so much that it has become hard to question it by the masses; the masses who are too uneducated to question their own heretical faith and traditions. But now that the world is rapidly evolving, the access to knowledge has evoked an awareness of many lower caste or ‘Dalit’ Muslims. They no longer wish to be oppressed for their ethnicity or rootless principles of the old generations to guarantee the survival of the higher caste Muslims or ‘Ashrafs’. In recent years, many have stood against the rules of the caste system. As the oppressed no longer wishes to be oppressed, they also show acts of violence against the rulers who destined them the life they currently have. Considering they are usually poor and uneducated, and they might do violent actions, this can threaten not only Indians but the whole world; especially because the ISIS can easily fund a troop of hungry men who are looking forward to revenge their masters and others for all the unjust discriminations. Therefore for the sake of social security and stopping the disrepute for followers of Islam, the entire Islamic nation must consider taking actions against practicing Caste, regardless of where they come from. Since the teachings of the Quran and the Sunnah of the Prophet (PBUH) invite all Muslims to practice equality and brotherhood in the Ummah, this article would find the practical ways to abolish the caste-system through the Islamic liturgical texts and traditions.Keywords: Dalit Muslims, Islam in India, caste system, justice in Islam, violence

Authors: Manoj Kumar Dutta
Abstract:
Wavelength division multiplexing (WDM) technology is the most promising technology for the proper utilization of huge raw bandwidth provided by an optical fiber. One of the key problems in implementing the all-optical WDM network is the packet contention. This problem can be solved by several different techniques. In time domain approach the packet contention can be reduced by incorporating fiber delay lines (FDLs) as optical buffer in the switch architecture. Different types of buffering architectures are reported in literatures. In the present paper a comparative performance analysis of three most popular FDL architectures are presented in order to obtain the best contention resolution performance. The analysis is further extended to consider the effect of different fiber non-linearities on the network performance.Keywords: WDM network, contention resolution, optical buffering, non-linearity, throughput

Authors: Venkateswarlu Kappara
Abstract:
The term ‘Dharma’ is complex and ubiquitous. It has no equivalent word in English Initially applied to Aryans. In Rig Veda, it appears in a number of places with different meanings. The word Dharma comes from the roots word ‘dhr’ (Dhri-Dharayatetiiti Dharmaha). Principles of Dharma are all pervading. The closest synonyms for Dharma in English is ‘Righteousness.’ In a holy book Mahabharata, it is mentioned that Dharma destroys those who destroy it, Dharma Protects those who protect it. Also, Dharma might be shadowed, now and then by evil forces, but at the end, Dharma always triumphs. This line embodies the eternal victory of good over evil. In Mahabharata, Lord Krishna says Dharma upholds both, this worldly and other worldly affairs. Rig Veda says, ‘O Indra! Lead us on the path of Rta, on the right path over all evils.’ For Buddhists, Dharma most often means the body of teachings expounded by the Buddha. The Dharma is one of the three Jewels (Tri Ratnas) of Buddhism under which the followers take refuge. They are: the ‘Buddha’ meaning the minds perfection or enlightenment, the Dharma, meaning the teachings and the methods of the Buddha, and the Sangha meaning those awakened people who provide guidance and support followers. Buddha denies a separate permanent ‘I.’ Buddha Accepts Suffering (Dukka). Change / impermanence (Anicca) and not– self (Annatta) Dharma in the Buddhist scriptures has a variety of meanings including ‘phenomenon’ and ‘nature’ or ‘characteristic.’ For Sikhs, the word ‘Dharma’ means the ‘path’ of righteousness’ The Sikh scriptures attempt to answer the exposition of Dharma. The main Holy Scripture of the Sikh religion is called the Guru Granth Sahib. The faithful people are fully bound to do whatever the Dharma wants them to do. Such is the name of the Immaculate Lord. Only one who has faith comes to know such a state of mind. The righteous judge of Dharma, by the Hukam of God’s Command, sits and Administers true justice. From Dharma flow wealth and pleasure. The study indicates that in Sikh religion, the Dharma is the path of righteousness; In Buddhism, the mind’s perfection of enlightenment, and in Hinduism, it is non-violence, purity, truth, control of senses, not coveting the property of others. The comparative study implies that all religions dealt with Dharma for welfare of the mankind. The methodology adapted is theoretical, analytical and comparative. The present study indicates how far Indian philosophical systems influenced the present circumstances and how far the present system is not compatible with Ancient philosophical systems. A tentative generalization would be that the present system which is mostly influenced by the British Governance may not totally reflect the ancient norms. However, the mental make-up continues to be influenced by Ancient philosophical systems.Keywords: Dharma, Dukka (suffering), Rakshati, righteous

Authors: Sandeep Kumar, Naveen Gupta
Abstract:
The propagation of the Non-Gaussian laser beam results in strong self-focusing as compare to the Gaussian laser beam, which helps to achieve a prerequisite of the plasma-based electron, Terahertz generation, and higher harmonic generations. The theoretical investigation on the evolution of non-Gaussian laser beam through the collisional plasma with ramped density has been presented. The non-uniform irradiance over the cross-section of the laser beam results in redistribution of the carriers that modifies the optical response of the plasma in such a way that the plasma behaves like a converging lens to the laser beam. The formulation is based on finding a semi-analytical solution of the nonlinear Schrodinger wave equation (NLSE) with the help of variational theory. It has been observed that the decentred parameter ‘q’ of laser and wavenumber of ripples of medium contribute to providing the required conditions for the improvement of self-focusing.Keywords: non-Gaussian beam, collisional plasma, variational theory, self-focusing

Authors: Vinod Kumar Arya
Abstract:
Creep analysis of a thick-walled composite anisotropic cylinder under internal pressure and considering large strains is presented. Using a threshold creep law for composite materials, expressions for stresses, strains, and strain rates are derived for several anisotropic cases. Numerical results, presented through several graphs and tables, depict the effect of anisotropy on the stress, strain, and strain rate distributions. Since for a specific type of material anisotropy described in the paper, these quantities are found to have the lowest values at the inner radius (the potential location of cylinder failure), it is concluded that by employing such an anisotropic material for the design of a thick-walled cylinder a longer service life for the cylinder may be achieved.Keywords: creep, composites, large strains, thick-walled cylinders, anisotropy

Haryana has a very rich ancient history right from the Stone Age. It is known as the cradle of civilization. During the Buddha period, Haryana was very prosperous. Buddha also visited this region during the travel of the northwest province of British India. In this research work, the authors describe the Buddhist trail in Haryana and the tangible heritage of Buddhism, which were built in the respect and memory of the Buddha's journey like Stupa, Monasteries, Pillar, sculptures, etc. Several stupas like Chaneti Stupa, Thanesar Stupa, Agroha stupa, Adibadri, Katrawali, Assandh Stupa, and many monasteries were come into light during the excavation and exploration in Haryana as well as a lot of Buddhist sculptures also found.Keywords: archaeology, Buddhism, exploration, excavations, stupa

Abstract:
Pearl millet is a climate-resilient nutritious crop. We report iron and zinc content QTLs from 3 divergent locations. The content of grain Fe in the RILs ranged between 36 and 114 mg/kg, and that of Zn from 20 to 106 mg/kg across the three years at over 3 locations (Delhi, Dharwad, and Jodhpur). We used SSRs to generate a linkage map using 210 F₆ RIL derived from the (PPMI 683 × PPMI 627) cross. The linkage map of 151 loci was 3403.6 cM in length. QTL analysis revealed a total of 22 QTLs for both traits at all locations. Inside QTLs, candidate genes were identified using bioinformatics approaches.Keywords: yield, pearl millet, QTL mapping, multi-environment, RILs
