The Mah?bh?rata is a very vast literature and is treated as a significant source of evidence on the socio-political-economic development of India at that time. In this outstanding classic, the time has been described in so many places.In Mah?bh?rata, time has been portrayed as an all-pervading supreme deity. In the section of Bh?g?vad Gita, we see that time occupies that highest place as well and has become one with the divine entity. Lord Krishna was identifying himself with K?la. Supremacy of time has been established here.In the ?hantiparva, section CCXXXI (231), there is an interesting conversation between Yudhisthira and Pitamoho Bhishma where Yudhisthira wanted to know some basic questions about the universe and the nature of time. In this section we can find a detailed time measurement process stated by Vy?sa. In Mah?bh?rata, time is itself divine and cyclic in nature. It shows a special characteristic of Hinduism. The concept of cyclical time is closely associated with the concept of soul or ?tman in Hinduism.

The main purpose of this paper is to examine the long- and short-run causal relationship between the economic development and carbon emissions level and to examine the existence of EKC hypothesis in Ranchi, Jharkhand. The data analysis is done for the period 2001-2020, which covers 20 years and the variable selected for analysis are CO2 emissions level and real per capita Gross District Domestic Product of Ranchi, Jharkhand. The data was collected from different sources. To investigate the short- and long-run relationship between these two variables, the ARDL co-integration test was performed and to test the causal relationship between the variables, Granger Causality test was applied. Finally, to test the EKC hypothesis, OLS (Ordinary Least Square) regression was performed. The results of ARDL co-integration test implies that there is a long- and short-run relationship or co-integration among the variables CO2 emissions and real per capita GDDP. The Granger Causality test results implies that there is unidirectional relationship between LNCO2 and LNPCGDDP, i.e., Carbon emissions does Granger cause per capita real GDDP. The results of quadratic form of EKC model shows that there is evidence of inverted U-shaped curve and the result of cubic form of EKC model indicates that there is an inverted N-shaped curve in Ranchi, Jharkhand.

Abstract:-Using rib on the absorber plate, an experimental study has been conducted to improve the efficiency of a solar air heater. The analysis of the thermal performance of a Solar Air Heater (SAH) with S rib with gaps, S rib without gaps and plain observer plate has been carried out in this research for varying mass flow rates on the SAH. To verify the performance enhancement, experimental outputs including outlet air temperature, and thermal efficiency were assessed. The maximum thermal efficiency of the S rib with gap absorber plate SAH were determined to be 78% at a mass flow rate of 0.045 kg/s, respectively 27.81% and 37.27% higher than the S continuous rib and without rib SAH. This study demonstrated that for the parameter under investigation, S-shaped ribs with gaps in a flow configuration offer superior thermal performance over continues ribs and smooth plate SAH

Cholinoceptors are specialized proteins observed on the surfaces of the cells. They give response to acetyl choline, a neurotransmitter that transmits signals especially across the synapses in the nervous system. Cholinoceptors play a role in transmitting messages between nerve cells and other types of cells namely muscle cells. Cholinoceptors are divided into nicotinic receptors and muscarinic receptors. Nicotinic receotors consist of five subunits. Nicotinic receptors play an important role in synaptic in the nervous system and these receptors are participated in muscle contraction, cognitive functions, memory and attention. Drugs that target nicotinic receptors are used for smoking cessation aids and treatments for neuro degenerative diseases like alzheimers. Muscarinic receptors consist of five subtypes namely M1, M2, M3, M4 and M5 receptors. Muscarinic agonist can be used to enhance salivary and bronchial secretions. Muscarinic antagonists are used to treat overactive bladder and certain gastro intestinal disorders. Finally it is concluded that cholinoceptors are fundamental components of the cholinergic signalling system and regulate vital bodily functions from muscle contractions to cognitive processes.

Introduction: Stress among teachers can have a range of causes, including heavy workloads, lack of support, conflicting demands, high stakes accountability, and challenging students or working conditions. This can lead to physical and mental health problems which can be reduced by Tai chi exercises. Tai chi (TC), as it is more commonly known outside of Asia, is an ancient Chinese mind-body exercise that is practiced worldwide by millions of people daily with the belief that it has potent healing effects upon the practitioner and is a fundamental path for longevity. Health-related quality of life (HRQOL) serves as a comprehensive measure of patient well-being, and it reflects patient perceptions of personal health and life satisfaction over a period of time. The 36-Item Short Form Health Survey questionnaire (SF-36) is a very popular instrument for evaluating Health-Related Quality of Life.

Abstract-: Naguib Mahfouz has recorded modern Egyptian history and society in a chronological order in his writings and especially in the novels. He has taken up issues like social changes, politics, gender, class conflict, morality, exploitation and oppression. "The Beginning and the End" echoes the spirit of Egypt itself - a nation that endured and transcended its share of challenges, emerging stronger and wiser. As the novel traverses the landscape of social, political, the story of ordinary people and the day to day's affairs of their life which could be seen through and economic shifts, it pays homage to the ordinary Egyptian whose resilience formed the foundation of a nation's progress. The story of Nefisa is a story of transformation, shift in family dynamics and most importantly the lenses of unending problems coupled with social prejudice in the name of tradition i.e. family honor.

Expeditious and unchecked urban expansion has significantly altered the urban environments. This has warranted the need of understanding, monitoring and analyzing the spatial patterns of urban growth. Relative Shannon Entropy is widely used metrics for assessment of pattern and the extent of urban growth in cities. Thereupon, this research paper pertains to quantify and monitor the patterns and dynamics of urban growth using Relative Shannon Entropy with integration of Geospatial technology in the city of Haldwani, Uttarakhand. In this study, land use land cover maps were extracted using satellite imageries of LISS IV and Sentinel II for 2005-2019 time periods. Subsequently, built-up, road network and the core of the city were extracted from the satellite data for the years 2005, 2008, 2013 and 2019. Eventually, Relative Shannon entropy (RE) was computed with reference to the core and the major roads for 2005-2008, 2008-2013 and 2013-2019 time periods. It has been observed that the obtained RE values exhibits that the pattern of urban growth in the city was a compact in the earlier period (2005), which in due course of time (2019) has changed to a dispersed pattern of urban expansion concerning both the core and the roads of the city. This research work thus enables in understanding the spatio-temporal pattern of urban growth in the city for effective land use planning in the city for sustainable urbanism.
