Attractiveness of Varanasi as a tourist destination: perspective of foreign tourists
(2007) Debadyuti Das; Pratap K.J. Mohapatra; Sushil Kumar Sharma; Ashutosh Sarkar
The present paper examines the attractiveness of Varanasi as a tourist destination from the perspective of foreign tourists considering several important dimensions simultaneously. These are demographic characteristics of tourists, their expectation on touristic attributes of the destination as also satisfaction with the same and finally holistic impressions of the destination. A factor analysis carried out on 24 touristic attributes pertaining to the expectation of visitors gives rise to seven meaningful constructs. Results of step-wise multiple regression analysis between the perceived attractiveness and the above seven constructs reveal the importance of each of these seven constructs in explaining the perceived attractiveness of the destination. Holistic impressions of Varanasi reveal that it is a city embodying the essence of Indian spiritualism and mysticism with Ganges and Ghats forming the heart of the city. © 2007 Inderscience Enterprises Ltd.
Preparation of high-Tc superconducting thin films of Tl-Ca-Ba-Cu-O by the chemical spray pyrolysis technique
(1992) K.K. Verma; A.K. Sexena; A.K. Singh; R.S. Tiwari; O.N. Srivastava
Thin films of the Tl-Ca-Ba-Cu-O system have been prepared on MgO and YSZ single-crystal substrates by a simple chemical process (the spray pyrolysis technique). Since Tl is toxic, the Tl-Ca-Ba-Cu-O films were prepared by a two step process. Firstly, precursor (Ca-Ba-Cu-O) films were prepared followed by diffusion of Tl derived by vaporizing Tl2O3 in a closed system under oxygen flow. A new feature found in the present investigation is that the Tc (R=0) of the Tl-Ca-Ba-Cu-O films has been found to depend upon the microstructural characteristics of the precursor films which can be varied by annealing these films. The Tc (R=0) of the Tl-Ca-Ba-Cu-O HTSCs films prepared from the annealed precursor films has been found to be higher than in the films prepared from the as-deposited precursor films. As, for example, in the case of a film on a MgO substrate, the Tc (R=0) has been enhanced from approximately 90 K to approximately 98 K. The highest T c obtained by the authors for the films synthesized from the annealed precursor films on YSZ substrates corresponds to approximately 103 K. The XRD reveals the biphasic (2223/2122) nature of the films. The microstructural characteristics of the films as monitored by SEM reveals the partially oriented nature of the Tl-Ca-Ba-Cu-O film.

Role of Boron as Priming Agent on Biochemical and Antioxidant System in Two Wheat Varieties Against Heat Stress
(Springer, 2023) Payal Chakraborty; Padmanabh Dwivedi
In agriculture, the selection of healthy and vigorous seeds is critical, so seeds must be of high quality. Seed priming is a reliable and commercial strategy for improving seed germination and seedling establishment under stressful conditions, whether biotic or abiotic. Heat stress occurs when temperature rises above a particular point and results in permanent irreversible damage to plants, whereas, heat stress that primarily affects crops during their reproductive or grain-filling stages, is referred as terminal heat stress. The present experiment deals with treating two varieties of wheat (HUW-468: Temperature sensitive and HUW-510: Temperature resistant) using boric acid and borax as priming agents and evaluating their effect on different parameters including biochemical (Hydrogen peroxide, Malondialdehyde, and Proline) and antioxidant parameters (Superoxide dismutase, Catalase, Ascorbate peroxidase, and Glutathione reductase) by sowing them under two different conditions (Timely and Late sown) for evaluating effect of priming agents on heat stress on different days of study. The results obtained indicate that primed seedlings grew better and were more resilient to stress, and this was due in part to lower ROS production, stronger membrane stability, a strong antioxidant defense system, and preservation of a strong and healthy crop stand. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
A Tertiary Trisomic in Barley (Hordeum vulgare L.)
(1977) Ganesh Prasad
Tertiary trisomics which occur in the selfed progeny of interchange heterozygotes, have gained considerable importance in genetics and breeding of barley. Ramage and Tuleen (1964) proposed the use of ‘Balanced Tertiary Trisomics’ (BTT) for maintaining lines of lethal and sterile genes. The concept of ‘Hybrid Barley’ production through the use of BTT was given by Ramage (1963, 1965) and a hybrid barley variety was released in U.S.A. (Ramage and Wiebe 1969). The present paper reports a tertiary trisomic which was isolated from the progeny of a gamma-ray induced translocation T 2-6 in barley. © 1977, Japan Mendel Society, International Society of Cytology.

THE MUSICAL REPRESENTATION OF SRI LANKAN KAFFIRS
(Logos Verlag Berlin GmbH, 2023) Geethika Abeysekara; Chinthaka Prageeth Meddegoda
This study presents a very small community within the Sinhalese context of Sri Lanka in light of academic interest: the Kaffirs. Their communal history reaches far back into colonial times, and they did not distinguish clearly from which territories in Africa these Kaffirs, an expression introduced by Portuguese rulers for slaves and servants brought to Sri Lanka from African shores, came and how they identify. Currently, Kaffirs are seen through the gaze of public writings and common biases. They are believed to have their performance styles and their strong association with the drum, dance, and vocal genres integrated into the canon of Sinhalese traditions. One specific vocal expression is the singing of manja songs, which are introduced and roughly analysed in this short paper. Manja songs are not so widely known to all people living in Sri Lanka. A specific study of these songs has not yet taken place. The main methods used are micro-analysis, literature studies, and open interviews with those who are connected to Kaffirs, either as members of the group or as people related to their studies and performing arts. Beyond presenting the exciting text repertoire, it is to connect the musical skills that come with this way of singing with related arts such as dancing and drumming. The Kaffirs’ performance potentials are widely underestimated. Many Kaffirs were integrated, through marriage and social subordination, into the current society. Yet, it is important to focus on the snippets in the history of specific performance skills and their relatedness to another continent in order to help understand global issues and their future. © 2023, Logos Verlag Berlin GmbH.

An introduction to tantric philosophy: The Paramarthasara of Abhinavagupta with the commentary of Yogaraja
(Taylor and Francis, 2014) Lyne Bansat-Boudon; Kamaleshadatta Tripathi
The Paramarthasara, or 'Essence of Ultimate Reality', is a work of the Kashmirian polymath Abhinavagupta (tenth-eleventh centuries). It is a brief treatise in which the author outlines the doctrine of which he is a notable exponent, namely nondualistic Śaivism, which he designates in his works as the Trika, or 'Triad' of three principles: Śiva, Śakti and the embodied soul (nara). The main interest of the Paramarthasara is not only that it serves as an introduction to the established doctrine of a tradition, but also advances the notion of jivanmukti, 'liberation in this life', as its core theme. Further, it does not confine itself to an exposition of the doctrine as such but at times hints at a second sense lying beneath the evident sense, namely esoteric techniques and practices that are at the heart of the philosophical discourse. Its commentator, Yogaraja (eleventh century), excels in detecting and clarifying those various levels of meaning. An Introduction to Tantric Philosophy presents, along with a critically revised Sanskrit text, the first annotated English translation of both Abhinavagupta's Paramarthasara and Yogaraja's commentary. This book will be of interest to Indologists, as well as to specialists and students of Religion, Tantric studies and Philosophy. © 2011 Lyne Bansat-Boudon and Kamaleshadatta Tripathi.

A hybrid deep learning model for COVID-19 prediction and current status of clinical trials worldwide
(Tech Science Press, 2020) Shwet Ketu; Pramod Kumar Mishra
Infections or virus-based diseases are a significant threat to human societies and could affect the whole world within a very short time-span. Corona Virus Disease-2019 (COVID-19), also known as novel coronavirus or SARSCoV- 2 (Severe Acute Respiratory Syndrome-Coronavirus-2), is a respiratory based touch contiguous disease. The catastrophic situation resulting from the COVID-19 pandemic posed a serious threat to societies globally. The whole world is making tremendous efforts to combat this life-threatening disease. For taking remedial action and planning preventive measures on time, there is an urgent need for efficient prediction models to confront the COVID-19 outbreak. A deep learning-based ARIMA-LSTM hybrid model is proposed in this article for predicting the COVID-19 outbreak by utilizing real-time information from the WHO's daily bulletin report as well as provides information regarding clinical trials across the world. To evaluate the suitability and performance of our proposed model compared to other well-established prediction models, an experimental study has been performed. To estimate the prediction results, the three performance measures, i.e., Root Mean Square Error (RMSE), Coefficient of determination (R2 Score), and Mean Absolute Percentage Error (MAPE) have been employed. The prediction results of fifty countries substantiated the fact that the proposed ARIMA-LSTM hybrid model performs very well as compared to other models. The proposed model archives the lowest RMSE, lowest MAPE, and highest R2 Score throughout the testing, under varied selection criteria (country- wise). This article aims to contribute a deep learning-based solution for the wellbeing of livings and to provide the current status of clinical trials across the globe. © 2021 Tech Science Press.
