The advance of monsoon over the Indian sub-continent is not a continuous process. It advances in a phased manner. It has been observed from large sample of the data that the monsoon current often stagnates outside northwest India. Gujarat, northwest Madhya Pradesh and west Uttar Pradesh for a long period resulting in delaying its advance considerably over these areas. The cause of such prolonged stagnation can be identified to the mechanic Himalayas - Tibetan plateau on the mid-tropospheric westerly flow in absence of any synoptic scale forcing over north India. During 1976, 1982 and 1991 there was prolonged stagnation of southwest monsoon over northwest India and neighbouring areas and, in 1985, it was over north Konkan during June-July. In those years, the sub-tropical ridge (STR) in the middle troposphere over India was weak or absent during the initial phase of advance of monsoon. In absence of the STR, the westerly trough activity in the mid-tropospheric levels extended to southern latitude disrupting the monsoon flow and bringing prolonged stagnation. The observation was confirmed on a test study conducted during the prolonged stagnation of the monsoon of 1995. On the other hand, in the year 1990, the mid- tropospheric STR became prominent from middle of June over north India and it helped in restricting southward extension of westerly troughs. Consequently the equatorial trough remained organize gradually over north India and caused the gradual advance of SW monsoon over the entire country without considerable.

Development economics is about understanding how and why lives and livelihoods change. This book is about economic development in the village of Palanpur, in Moradabad district, Uttar Pradesh, in north India. It draws on seven decades of detailed data collection by a team of dedicated development economists to describe the evolution of Palanpur’s economy, its society, and its politics. The emerging story of integration of the village economy with the outside world is placed against the backdrop of a rapidly transforming India and, in turn, helps to understand the transformation. The role of, and scope for, public policy in shaping the lives of individuals is examined. The book describes how changes in Palanpur’s economy since the late 1950s were initially driven by the advance of agriculture through land reforms, the expansion of irrigation, and the introduction of ‘green revolution’ technologies. Then, since the mid-1980s, newly emerging off-farm opportunities in nearby towns and outside agriculture became the key drivers of growth and change. These key forces of change have profoundly influenced poverty, income mobility, and inequality in Palanpur. Village institutions such as those governing access to land are shown to have evolved in subtle but clear ways over time, while individual entrepreneurship and initiative is found to play a critical role in driving and responding to the forces of change. And yet, against a backdrop of real economic growth and structural transformation, the book documents how human development outcomes have shown only weak progress and remain stubbornly resistant to change.

This paper calculates the mean duration of the postpartum amenorrhoea (PPA) and examines its demographic, and socioeconomic correlates in rural north India, using data collected through 'retrospective' (last but one child) as well as 'current status' (last child) reporting of the duration of PPA.The mean duration of PPA was higher in the current status than in the retrospective data;n the difference being statistically significant. However, for the same mothers who gave PPA information in both the data sets, the difference in mean duration of PPA was not statistically significant. The correlates were identical in both the data sets. The current status data were more complete in terms of the coverage, and perhaps less distorted by reporting errors caused by recall lapse.A positive relationship of the mean duration of PPA was found with longer breast-feeding, higher parity and age of mother at the birth of the child, and the survival status of the child. An inverse relationship was found with higher education of a woman, higher education of her husband and higher socioeconomic status of her household, these variables possibly acting as proxies for women's better nutritional status.

BACKGROUND: Maternal health is an important aspect for the development of any country in terms of increasing equity and reducing poverty. For reduction of maternal mortality and morbidity Government of India launched National health mission (NHM). Some of the major initiatives under NHM are– ASHA (Accredited Social Health Activist), JSY/JSSK (Janani Suraksha Yojana / Janani Shishu Suraksha Karyakaram), National mobile medical units, National ambulance services. METHODS: A retrospective observational study was performed in department of Obstetrics and Gynaecology, G.S.V.M Medical College, Kanpur, Uttar Pradesh which is a low performing state, during the period of 2018 to 2019. A total of 5134 obstetric patients including 1032 low general condition patients were included over duration of 20 months since January 2018 to august 2019. This observational study collected information regarding number of deliveries in different years in this tertiary care hospital, effect on availability of health facilities and antenatal care to the antenatal women after introduction of JSY, ASHA and ambulance services. CONCLUSIONS: After JSY there is major difference in OPD admission and institutional delivery rate. Ambulance services had major contributory role in reducing maternal mortality and morbidity. There is need to improve performance of ASHA by proper supervision and monitoring.

Background: Nucleic acid amplification test (NAAT) is considered gold standard in the molecular diagnosis of CoV-2 infection but since it is costly, labor intensive and needs technical expertise, rapid chromatographic immunoassay for the qualitative detection of specific antigens to SARS CoV-2 have been devised. Objectives of this study was to compare the results of Antigen test and NAAT for CoV-2 infection carried out during the months of July and August 2020 by single tertiary care hospital in Lucknow, Uttar Pradesh and to determine the utility of rapid antigen test in the SARS CoV-2 diagnosis.Methods: All the patients who came to our hospital seeking admission during July 2020 and August 2020 were included in the study. A total of 1000 patients were included in this study.Results: Out of a total 1000 cases which were included in the study, 769 cases (76.9%) were found to be SARS CoV-2 negative by both antigen and CBNAAT, 100 cases (10.0%) were SARS CoV-2 positive by both antigen and CBNAAT tests. But in 131 cases (13.1%), antigen was not able to pick up the disease. It was also found that the Cycle Threshold (Ct) value for the discordant group was higher (Mean E= 28, Mean N2=33) when compared to the group where antigen was positive.Conclusions: The present study establishes the role of rapid antigen tests in contributing to the quick, point of care diagnosis of SARS CoV-2. These assays are safe, simple, and fast and can be used in local clinics and hospitals. These tests are very important for real-time patient management and infection control decision.

Abstract. In this paper, interannual variability of tropospheric air temperatures over the Asian summer monsoon region during the pre-monsoon months is examined in relation to Indian summer monsoon rainfall (ISMR; June to September total rainfall). For this purpose, monthly grid-point temperatures in the entire troposphere over the Asian summer monsoon region and ISMR data for the period 1949–2012 have been used. Spatial correlation patterns are investigated between the temperature field in the lower tropospheric levels during May over the Asian summer monsoon region and ISMR. The results indicate a strong and significant northwest–southeast dipole structure in the spatial correlations over the Indian region, with highly significant positive (negative) correlations over the regions of north India and the western Tibetan Plateau region – region R1 (north Bay of Bengal: region R2). The observed dipole is seen significantly up to a level of 850 hPa and eventually disappears at 700 hPa. Thermal indices evaluated at 850 hPa level, based on average air temperatures over the north India and western Tibetan Plateau region (TI1) and the north Bay of Bengal region (TI2) during May, show a strong, significant relationship with the ISMR. The results are found to be consistent and robust, especially in the case of TI1 during the period of analysis. A physical mechanism for the relationship between these indices and ISMR is proposed. Finally the composite annual cycle of tropospheric air temperature over R1 during flood/drought years of ISMR is examined. The study brings out the importance of the TI1 in the prediction of flood/drought conditions over the Indian subcontinent.

AbstractStarting in the late 19 th century, workers from north India came to constitute the backbone of the urban and industrial labour force in Calcutta and neighboring mill municipalities. As they settled in and around the colonial metropolis, these Hindustani workers maintained strong connections with their rural homes. One generation after the other, they reproduced this dual settlement over the following decades. This bi-local structure of labour circulation, which linked village and city through the constant coming and going of men and women, progressively broke down from the late 20 th century onwards, following the closure of the large textile, engineering and paper industries which underpinned the economic vitality of the Calcutta region. The article sketches out the history of this socio-spatial configuration over the second half of the 20 th century, through the life histories of two migrant Hindustani workers. Born around 1940, Siraj Prajapati and Mohan Lal both spent the greater part of their working lives in Calcutta's industrial suburbs. Siraj, a potter by caste, was engaged in the artisanal production tea-cups in Howrah. Born into one of the most marginalized sections of north Indian society, Mohan managed to train as a mason, and was employed in the Titagarh Paper Mill through the 1960s and 70s. Both have now settled back in their respective villages of eastern Uttar Pradesh. Teasing out the contradictory ways in which both men frame their life trajectories, the article contributes a micro-perspective to the social history of rural-urban migration in post-colonial north India.

AbstractIn South Asia, Muslim reformers have often attempted to ‘rationalize’ and gentrify the everyday behaviour of ordinary Muslims. Yet, despite the existence of discussions of contraceptive techniques in the yūnān-ī tibb curricula of 19th century India and the apparent affinity between rationalism and fertility regulation, contraception was rarely discussed in public debates involving Muslim reformers. In this paper we discuss some of the relationships between élite debates among Muslim leaders and the grassroots behaviour of villagers in rural Bijnor, in western Uttar Pradesh. Villagers' voices are ambiguous, with fears for mother and child health surfacing as often as concerns for religious orthodoxy and one's destiny in the afterlife. In addition, many of the villagers' views of Islam were much more restrictive than those of the locally accepted authoritative voices: although the staff at Daru'l ‘Ulūm, Deoband, saw much modern contraception as an unwelcome sign of modernity, their discussions of the acceptability of family planning circled round notions of majbūrī [compulsion], repentance, and the unfathomable mercy of Allah. We conclude that focusing on local notions of Islam to understand the fertility behaviour of rural Muslims is less fruitful than considering a “political economy of hopelessness” that, increasingly since 1947, affects many Muslims in north India.
