The present paper, as regards its subject-matter though not in form, is part of a general investigation of the rainfall of India, which has occupied much of my spare time for some years past, and the results of which are already partly embodied in a memoir which I hope, in the course of a few months, to issue as an official publication of the Indian Meteorological Office. The idea that the snowfall of the Himalaya exercises a direct and important influence on the dry land winds of North-Western India is not now put forward for the first time. It has been the subject of frequent reference in the annual reports on the meteorology of India since 1876, as well as elsewhere; and in a report on the administration of the India Meteorological Department lately issued, I summarised very briefly those points in the experience of the previous five years which have seemed to justify its provisional adoption as a basis for forecasting the probable character of the monsoon rains. Relying on this experience, in the month of June last, I put forward in the Government Gazette, a note giving warning of the probability of a prolonged period of drought in the approaching monsoon season, and the result, if not in exact accordance with the terms of the forecast, has been so far confirmatory of the general idea, as to induce me to put the facts of past experience formally on record, and thereby challenge attention to the subject. If I am right in the inference that the varying extent and thickness of the Himalayan snows exercise a great and prolonged influence on the climatic conditions and weather of the plains of North-Western India, it is probable, that with more or less modification according to the local geography, causes of a similar character will be found equally operative in other regions, and perhaps on an even more extensive scale.

The following notes, very nearly as they stand, were forwarded in July, 1861, by post to the late Colonel Baird Smith, for communication to the Eoyal Asiatic Society. The address got defaced in the mail-bags; and the parcel, after lying for several months in the Dead Letter Office, found its way back to Eoorkee. My observations have thus forfeited the advantage of correction and criticism from one so experienced in the subject to which they relate. Meanwhile, I have had some hurried opportunities of seeing and hearing more, and can thus make some alterations and additions.— H. B. M.

ABSTRACTThe reproductive performance of female Magra and Marwari sheep of the desert areas of north-western India was studied in relation to intermittent water deprivation, for a period of 39 months during which four breedings were completed. The control group received an ad libitum supply of water every day, while the water-restricted group was provided with water on the same 2 days each week only throughout the experimental period, except during the monsoon season. All the ewes were maintained on cultivated Cenchrus ciliaris pasture. No ill effect was noticed on the general health of the animals. Reproductive measures such as incidence and duration of oestrus, length of the oestrous cycle, conception rate, lambing rate, length of gestation, post-partum interval, inter-lambing period, post-lambing weight of ewes and birth weight of lambs were not significantly affected by the imposed water deprivation. The dailywatered ewes had a slightly, but not significantly higher gain in body weight than the water-restricted ewes. It wa^ concluded that ewes of these two breeds could be maintained on a twice weekly watering schedule for prolonged periods of time without having any adverse effect on their reproductive performance.

В статье рассмотрен международный опыт волонтерского движения в сфере сохранения памятников культуры как способ образовательной деятельности, включения человека в активную общественную жизнь. Целью исследования явился системно-исторический анализ развития волонтерского движения, связанного с сохранением культурного наследия за рубежом. Методологию работы составил структурно-функциональный подход в совокупности с теоретическими (анализ, сравнение, обобщение) и прикладными (сбор эмпирических данных, анализ результатов волонтерских практик) методами. Авторами выполнен обзорный анализ источников, изучены ведущие зарубежные практики, основные направления развития и популяризации реставрационного волонтерства за рубежом, проанализирована деятельность международных организаций охраны памятников. В ходе изысканий установлено, что реставрационное волонтерство прошло путь от локальных инициатив до явления, поддерживаемого на правительственном уровне, став полем плодотворного взаимодействия государственных структур и гражданского общества.The article discusses the international experience of the volunteer movement in the field of preservation of cultural monuments as a kind of educational activity, of a persons inclusion in an active public life. It was volunteer work that predetermined the formation of a special social niche for proactive citizens united by common interests, needs, and values. The leading approach used in the study is structural and functional, which allows identifying the features of the development of volunteering and its goals. This approach, combined with theoretical (analysis, comparison, generalization) and applied methods (empirical data collection, analysis of the results of volunteer practices), substantiates the aim of the study: a system-historical analysis of the development of the volunteer movement to preserve the cultural and historical heritage abroad. In the course of the study, a review analysis of the sources on the stated problem was carried out: annual reports of non-profit charitable organizations, guidelines for working with volunteers, educational programs for training volunteers, laws and regulations governing the scope of volunteer work. The leading foreign volunteer practices implemented on the basis of models of intersectoral social interaction were studied the main directions for the development and popularization of restoration volunteering abroad were identified the activities of international organizations for the protection of cultural monuments in the context of assistance in organizing volunteer projects for voluntary assistance to activists in restoration and emergency operations were analyzed. The conclusions drawn from the analysis of the sources helped to form a general idea of the features of volunteering, voluntary practices in the field of cultural heritage protection in each of the studied countries. The thesis is substantiated that from the moment of its formation to the present, restoration volunteering has gone from local initiatives to a social phenomenon supported at the government level. The volunteer environment in European countries is a strongly institutionalized social phenomenon that has legitimacy and reliability, both in the eyes of the public and in the eyes of public authorities. Based on the analysis of the characteristics of the volunteer movement, as well as the attraction of empirical data, it is established that modern volunteering abroad, playing a significant role in preserving the cultural and historical heritage, developing progress, democratizing society, includes global and national-regional components, in which a special role is given to the effective system of interaction between state structures and civil society, shows optimally effective forms and technologies of preserving historical heritage based on economic, social, historical, and cultural features of the countrys development in general and a specific region in particular.

ResumoA preocupação com o desenvolvimento sustentável e a sustentabilidade vai muito além dos cuidados com o meio ambiente, além do contexto histórico do desenvolvimento sustentável, relata uma perspectiva social mais abrangente, direitos humanos, questões de desenvolvimento social. O tema sustentabilidade vem se destacando não somente pela escassez de matéria-prima, mas também pela cobrança dos diversos públicos envolvidos, sejam eles clientes, fornecedores, funcionários e até mesmo o próprio governo; estes diversos públicos querem organizações focadas no objetivo socioambiental e a sua transparência quanto a suas ações para com assunto. O objetivo do artigo é, a partir dos relatórios anuais de uma empresa de participações e investimentos no período de 2012 a 2017, analisar a evolução do quadro de funcionários, números de acidentes, tempo de treinamento e investimentos em programas socioambientais dentro do contexto do desenvolvimento sustentável e sustentabilidade. A metodologia adotada foi uma análise documental por meio de um estudo de caso, verificando 6 relatórios anuais de sustentabilidade da empresa objeto do estudo, mediante verificação dos dados divulgados no site da organização. Os achados apontaram que a organização realizou investimentos em treinamentos e na diminuição da relação do número de acidentes. AbstractThe concern for sustainable development and sustainability goes far beyond caring for the environment reports beyond the context of sustainable development history, a broader social perspective, human rights, social development issues. The sustainability theme has been highlighted not only by the scarcity of raw materials, but also by the collection of the various publics involved, whether they are customers, suppliers, employees and even the government itself, these various publics want organizations focused on the socio-environmental objective and also their transparency regarding their actions towards the subject. The objective of the article is, based on the annual reports of a participation and investment company from 2012 to 2017, to analyze the evolution of the staff, accident numbers, training time and investments in environmental partner programs within the context of sustainable development and sustainability.

Selection potential based on differential fertility and mortality has been computed for six tribal groups inhabiting different geo-climatic conditions, namely: Sahariya, Mina and Bhil of the State of Rajasthan, north-western India, and Munda, Santal and Lodha of the State of West Bengal, eastern India. Irrespective of the methodology, the total index of selection was found to be highest among Lodhas (0·668), followed by Sahariyas (0·524), Santals (0·462), Bhils (0·386), Mundas (0·353) and Minas (0·334). Incidently, Lodha and Sahariya are two of the seventy-four notified primitive tribal groups of India, and these two study populations show the highest index of total selection, mainly because of a higher embryonic and postnatal mortality.The relative contribution of the fertility component to the index of total selection is higher than the corresponding mortality component in all tribal groups.The analysis of postnatal mortality components indicates that childhood mortality constitutes the bulk of postnatal mortality, suggesting that children under 5 years need better health care in these tribal groups.

Abstract In this study, an attempt has been made to examine the recent rainfall variability by means of daily rainfall data of 33 well spread stations over dryland ecosystem of Rajasthan in north western India during 1961-2017. For trend analysis, Mann-Kendall, Sen’s slope estimator and simple linear regression test have been used (at 95% confidence level). The results have shown a high interannual variability in rainfall occurrence varying from 277 mm (in year 2002) to 839 mm (in year 1975) with mean of 583 mm over this dryland ecosystem. Most of the rainfall deficit years have occurred with El-Nino years. The mean annual rainfall has shown a marginal non-significant upward trend over the ecosystem. The station-wise mean annual rainfall has revealed a significant rising trend over Barmer, Churu, Ganganagar, Jaisalmer and Pratapgarh stations. Interestingly, three year running average has shown a cyclic pattern of rainfall over dryland ecosystem under the changing climatic conditions. The spatial pattern has exhibited that the mean annual rainfall decreases from east and south east (more than 850 mm) to west and north west (less than 400 mm), which is mainly associated with the presence of Aravalli Mountains spreading north east to south west in central Rajasthan. Remarkably, majority of stations positioned in western parts of dryland ecosystem have shown increasing rainfall trends, whereas some stations located in eastern parts have recorded a non-significant declining trend. The magnitude of significant rising trend has varied from 5.34 mm/year (Pratapgarh station) to 2.17 mm/year (Jaisalmer station). Also, the frequency of heavy rainfall events has shown a positive trend with significant increasing trends over Bharatpur, Jaisalmer and Pratapgarh stations, whereas Bundi station has shown significant decreasing trend.

The main aim of the research is to propose options for nonimportables producing at rural territories to boost the development of agribusiness. One of the most possible and promising non-importable to be developed and which ensures sustainability is rural and ecotourism. We revised the development of Russian tourism with the help of statistical data and used the regressions method for different periods of time to understand whether the process was stable and positive. Another goal was to estimate whether the government procedures play real efficient role in the development of tourism industry of tourist destinations of the North Western Federal District, or the bottom up development is more appropriate for little tourist destinations. To analyze this hypothesis the tourism development from 2006 to 2016 in the regions the Northwestern Federal District was revised. The methods of theoretical research come from the analysis of theoretical research on the subject. The methods of empirical research are based on comparison, analogy and generalizations according to statistic and other officialdata.

Abstract. The vertical structure of atmospheric aerosols over the Indian mainland and the surrounding oceans and its spatial distinctiveness are characterized using long-term (2007–2020) spaceborne lidar observations, satellite-retrieved aerosol optical depths and assimilated aerosol single scattering albedo. The consequence of these on the spatial distribution of aerosol-induced atmospheric heating is estimated using radiative transfer calculations. The results show strong, seasonally varying zonal gradients in the concentrations and vertical extent of aerosols over the study region. In general, while over the oceans, aerosol concentrations decrease rather monotonically with increase in altitude (from its highest value near the surface), over the mainland, the concentrations initially increase from the surface to about 1 km before decreasing towards higher altitudes, in all seasons over Central India and during summer monsoon season in northern India. This is attributed to the seasonal variations in the source strengths and the atmospheric boundary layer dynamics. Compared to the surrounding oceans, where the vertical extent of aerosols is confined within 3 km, the aerosol extinction coefficients extend to considerably higher altitudes over the mainland, reaching as high as 6 km during pre-monsoon and monsoon seasons. Longitudinally, the vertical extent is highest around 75° E and decreasing gradually on either side over the peninsular India. In the west, the concentrations and vertical extent of aerosols are highest during summer/monsoon due to the lofting and strong advection of mineral dust and sea salt aerosols. Particulate depolarization ratio profiles affirm the ubiquity of dust aerosols in western India during monsoon. Dust aerosols are distributed all the way from surface to 6 km over the north-western semi-arid regions. While the presence of low-altitude dust aerosols decreases further east, the high-altitude (above 4 km) dust layers are observed to remain aloft throughout the year with seasonal variations in its zonal distribution over north-western India. Southern peninsular India and its surrounding oceans are marked with high-altitude (around 4 km) dust aerosols during the monsoon season. Radiative transfer calculations show that these changes in vertical distribution of aerosol loading and types result in enhanced atmospheric heating at the lower altitudes during pre-monsoon, with prominent heating within 2–3 km throughout the Indian region. These results will have large implications for aerosol-radiation interactions in regional climate simulations.

An investigation to evaluate the effect of foliar application of potassium and its spray schedule on yield and yield parameters in sweet orange cv. Jaffa was undertaken at experimental orchard, Department of Horticulture, CCS Haryana Agricultural University, Hisar during the year 2014-15. The results revealed that the foliar application of potassium nitrate at the rate of 2 and 4 % and potassium sulphate at 1.5 and 3.0 % significantly improved average fruit weight, fruit diameter, percentage of medium and large fruits, and fruit yield of sweet orange cv. Jaffa over control (water spray). The trend was vice-versa on the percentage of small fruits. The number of fruits per plant could not differ significantly due to various treatments. Among K sources and doses, foliar application of KNO3 at 4 % exhibited superiority over other treatments with respect to yield and yield parameters followed by KNO3 at lower dose (2 %) or K2SO4 at higher dose (3 %). Among various spray schedules, application of three sprays of K in the last week of April, May and August were found superior or at par in improving yield and yield parameters with 2 sprays in the last week of April and August. The fruit yield was recorded the highest (76.90 kg/plant) with a combination of the foliar application of KNO3 at 4 % and 2 sprays in the last week of April and August which was non-significant with KNO3 with an additional spray in the last week of May. The findings signify the importance of K spray in improving yield and yield parameters of sweet orange under semi-arid climatic conditions of north western India.

Background: Zizyphus xylopyrus (Retz.) Willd. (Rhamnaceae) is a straggling shrub or a small tree, armed with spines, found throughout north western India, Pakistan and China. Methods: The aerial and root barks, leaves and fruits of Zizyphus species are used in medicine for the treatment of various diseases such as weakness, liver complaints, obesity, diabetes, skin infections, fever, diarrhea, insomnia and digestive disorders. Ethanolic extract of leaves of Zizyphus xylopyrus (Retz) Willd was prepared by solvent extraction and subjected to study the protective effect against Indomethacin and HCl-EtOH induced ulcer using Ranitidine (100 mg/kg) and Omeprazole (8 mg/kg) as standard respectively. Results: Histopathological lesions with marked disorientation of the gastric epithelium was observed in negative control, while extract treated rats showed a better protected mucosa with intact epithelium in comparison to standard treated rats. Ulcer index and percentage ulcer protection also represent protecting effects of the extract. Conclusion: Ethanolic extract of Z. xylopyrus (Retz) Willd leaves extract was found to be significantly protective against gastric ulcers.
