 Abstract

Electron Paramagnetic Resonance (EPR) spectroscopy is a powerful tool for probing the paramagnetic properties of materials, providing valuable insights into their electronic structure and local environments. In this study, we investigate the paramagnetic behavior of Copper-Doped Glass with V2O3 as a dopant using EPR spectroscopy. The incorporation of copper ions into the glass matrix, coupled with the presence of V2O3, introduces paramagnetic centers that are of great interest for both fundamental research and potential technological applications. Our experimental setup involved careful sample preparation, precise control of temperature and magnetic field, and systematic data acquisition. EPR spectra were obtained, revealing distinctive paramagnetic signals attributed to the copper ions and their interactions with neighboring species. Through detailed spectral analysis, we elucidate the nature of these paramagnetic centers, providing valuable insights into their coordination environments and electron-spin interactions

 Abstract

The urgency to switch to renewable energy sources and improve their performance becomes important as traditional energy resources continue to run out. The design for linking a brushless DC motor with a modified rear axle for a regular car is shown in this paper. The Permanent Magnet Brushless DC motor runs with a broad spectrum of high torque capabilities and exhibits good efficiency. The most appropriate electric motor drive for electric vehicle applications is determined through a comparative analysis of the efficiency, weight, cost, cooling, maximum speed, fault tolerance, safety, and reliability of various motor drives, including switched reluctance motor, induction motor, permanent magnet brushless DC motor, and brushed DC motor. According to the study, permanent magnet brushless DC motor drives are the best option for electric vehicles. Automakers, governments, and customers are becoming more interested in electric vehicles (EVs) and hybrid EVs (HEVs) as environmental concerns rise. Researchers must create superior electric-drive systems since electric drives are the essential part of both EVs and HEVs. The overview of permanent-magnet brushless drives for EVs and HEVs in this research emphasises machine topologies, drive operations, and control approaches.

 Abstract

Diabetic-retinopathy is the leading cause of blindness in the working age population. So far the most effective treatment for these eye diseases is early detection through regular screenings. To decrease the cost of such screenings, we employ methods image processing techniques to automatically detect the presence of abnormalities in the retinal images obtained during the screenings. In this paper, we used two methods. First approach is that detection of lesions using minimum distance discriminat (MDD) algorithm with brightness adjustment procedure. Second method is detection of blood vessels using Krisch's method. Experimental results indicate that we are able to achieve 100% accuracy in terms of identifying all the retinal images with exudates while maintaining a 75% accuracy in correctly classifying the truly normal retinal images as normal and also detects the affected blood vessels in the retinal image . This translates to a huge amount of savings in terms of the number of retinal images that need to be manually reviewed by the ophthalmologists.

 Abstract

Rapid and high frequency in vitro multiple shoots and subsequent plantlets were developed in several plant species of arid forestry viz. Anogeissus acuminata, A.pendula, A. latifolia, A.sericea var. nummularia, A.sericea var. sericea, Calligonum polygonoides and Withania coagulans. In Prosopis cineraria, Tecomella undulata, Acacia senegal, Maytenus emerginata, Balanites aegyptiaca, Zizyphus nummularia and Z. mauritiana in vitro multiple shoots were induced at the high rate by using nodal shoot segments from mature trees, but root induction in differentiated shoots were not very high in few species. Dipcadi erythraeum - an endemic and endangered plant is differentiated into plantlet from in vitro cultures. Various explants (cotyledonary nodal segment and epicotyl of Anogeissus spp., nodal and apical shoot segments from mature plants) of 1.5-2.5 cm in length were placed on Murashige and Skoog's 1962(MS) basal medium supplemented with inorganic and organic addenda. Various growth regulators (auxins IAA, IBA, NAA and 2, 4-D and cytokinins; kinetin and BAP) were added from 0.1- 5.0 mg/l either alone or in combination to induce multiple shoots. Differentiated shoots could be further multiplied on fresh medium. Isolated shoots were rooted on MS basal and MS half strength basal salts medium with various concentrations of IAA, IBA and NAA. Plantlets of Anogeissus spp., Calligonum polygonoides, Withania coagulans and Dipcadi erythraeum were transferred into pots. . (N. S. Shekhawat et al. 1993,Rathore et al 1991,kaur et al 1992)

 Abstract

The present study has been undertaken to study the effects of different socio-economic and demographic factors on the fertility behaviour in District Bilaspur of Himachal Pradesh. A total sample comprises 150 households, out of which 75 households (sampled couples 87) were selected from rural area and 75 households (sampled couples 77) were selected from the urban area in District Bilaspur of Himachal Pradesh. Step wise forward regression analysis was applied to examine the effect of social, economic and demographic variables on total number of children ever born (TCEB) of the sampled women. In rural area the result of regression shows that total male surviving children was alone responsible for the 28 percent of variation in total no. of children ever born. Step wise regression analysis for rural area shows by including explanatory variable increases the value of R2 i. e. age of wife at the time of marriage 21 years or more to 40 percent, age of wife at the time of marriage 18 to 20 years to 48 percent, no. of children dead to 56 percent, education of wife above senior secondary school complete to 58 percent, wife working in private sector to 60 percent, husband working in private sector to 62 percent, decision about no. of children taken by both husband and wife to 64 percent, wife working in Government sector to 66 percent and duration of effective marriage 21 years or above to 67.5 percent. In urban area the result of regression shows that total male surviving children was alone responsible for the 26 percent of variation in total no. of children ever born. Step wise regression analysis for urban area shows by including explanatory variable increases the value of R2 i. e. duration effective marriage 21 or above to 37 percent, age of wife at the time of marriage 21 years or more to 44 percent, elders take decision about son preference to 48 percent, age of wife at the time of marriage 18 to 20 years to 50 percent, duration of effective marriage 6 to 10 years to 53 percent, duration of effective marriage 16 to 20 years to 56 percent, duration of effective marriage 11 to 15 years to 60 percent, husband working in Government sector to 63 percent and no. of children dead increase the value of R2 to 65 percent.

 Abstract

The aim of this study was to investigate the effect of a three-week yoga training program on badminton players' physical and psychological performance. A total of 30 badminton players, aged between 18 and 25 years, participated in the study. Participants were randomly assigned to either the experimental group, which received the yoga training program, or the control group, which did not receive any additional training. The yoga training program consisted of 60-minute sessions, conducted three times a week for three weeks. The sessions included various yoga postures, breathing exercises, and meditation techniques. The physical performance of the participants was measured using the Badminton-specific endurance shuttle run test (BESRT) and the badminton agility test (BAT). The psychological performance was measured using the Profile of Mood States (POMS) questionnaire. The results of the study showed a significant improvement in the physical performance of the experimental group compared to the control group, as evidenced by the BESRT and BAT scores. In conclusion, a three-week yoga training program can be an effective method of improving the physical and psychological performance of badminton players. The incorporation of yoga into the training programs of badminton players may be beneficial in enhancing their overall performance.

 Abstract

In a developing country like India reach of safe fuel for cooking is a constant problem particularly for socio-economically weaker sections of society. Intensity of this problem is very high in rural areas in comparison to urban areas. This led to high dependency of rural households on unsafe fuel for cooking such as fuel wood, cow dung cake and coal. The responsibility of collecting fuel wood from village commons and nearby forest areas lies on women and children. This process takes a lot of their energy and time. The smoke from these unsafe fuels emit a lot of harmful gases such as Co2, Co, So2, hydrocarbon and solid particulate matter, which adversely affect the health of women causing many health problems like irritation in eyes, cataract, skin infections, upper respiratory infection, burns etc. This also led to atmospheric pollution and increase in green house gases. NCR lies at the core of India, where a majority of households except Delhi all other sub-regions use unsafe fuel for cooking both in rural and urban areas. Scheduled caste households are at great disadvantage (both in rural and urban areas) in comparison to non-scheduled households in terms of safe fuel for cooking. Availability, socio-economic conditions and urbanisation are major factors deciding the type of fuel used for cooking.

 Abstract

Indian arid zone is characterized by high temperature and low and variable precipitation, which limit the scope for high crop productivity. However, these conditions greatly favor the development of high quality produce in a number of fruit crops such as date palm, ber, aonla, pomegranate, kinnow, lasoda and annona. The existing low productivity could be increased by following improved new technologies and inputs. It is now realized that there is a limited scope for quantum jump in fruit production in the traditional production areas. The amelioration of the extreme conditions is also considered vital for life support to the inhabitants of this area. The recent awareness regarding the potential of these ecologically fragile lands for production of quality produce has not only opened up scope for providing nutritional sustainability for the people of this region, but also for bringing in new areas to increase horticultural production (More et al., 2012). The area and yield potential of arid horticultural crops has increased many-fold because of the development of new varieties and agro-techniques in arid region.
