A review of rural development and poverty amelioration programmes in India
(2012) P.K. Tiwari; V.N. Sharma
Rural poverty in India is very much historical but now it has multiplied with the population explosion and unemployment situation. Tlie slogan 'Garibi Hatao ' was very much specific for poverty alleviation programmes. In India, a number of rural development programmes has been implemented in the Five Years Plans to raise income, provide employment, make masses literate and alleviate the poverty of rural poor. This paper critically evaluates different rural development programmes launched by the government during pre-independence and post-independence periods. The trend of poverty in the country is also discussed.
A stewardship of ramgarh lake in gorakhpur district: Uses, problems and management
(Institute of Indian Geographers, 2018) Alka Singh; V.N. Sharma
Water is essential for sustaining life and at the same time, it is an important component for almost all developmental plans, however, Growing population, urbanization and industrialization has led to considerable increase in demand of water for various purposes. The present work is focused on uses, deteriorating factors and suggestion for restoration of Ramgarh Lake. Ramgarh Lake (26º42′30′′N - 26º45′N & 83º24′20′′E- 83º25′20′′), covering an area of 576 hectare which is situated in the center of Gorakhpur district and this district exist in the north-eastern part of Uttar Pradesh. Large populations depend on this water body for fish, vegetable, water, irrigation, waste disposal site, washing site and recreational activity. Dumping of solid as well as liqid wastes has resulted in the uncontrolled growth of aquatic weeds, eutrophication and sedimentation, which have altered lake’s morphology, volume, depth and quality of water .Importance of lakes understood by the people and therefore serious measures are being taken towards the stewardships of water bodies. Ramgarh lake also being neglected in past, but now, this conservation of lake is estimated to ensure the better future of Gorakhpur city. © 2018 Institute of Indian Geographers. All rights reserved.
A survey of research in industrial geography in india
(Institute of Indian Geographers, 2014) V.N. Sharma; Anil Kumar Tiwari
Though, industries play a dominant role in the development of a country, yet researches on industrial phenomenon, especially in geography can be counted on fingers. Among Indian geographers, it has never been an issue of interest. However, some studies, surely, attract the scholars of industrial geography but there is a lack of specific studies on industrial development. Before independence, afew works were done in the field by Indian geographers who have mainly worked on different themes related to location and distribution pattern of industries, resource base for industries, industrial impact on urbanisation, environment impact, socio-economic impacts, industrial finance, industrial linkages, and analysis of some specific industries. Besides, policy oriented studies, de-industrialisation, impact of globalisation on industrial development and specific studies on sickness of industries and its management, are least accounted for research. The main purpose of the present paper is to outline a survey of researches in industrial geography done by Indian geographers.
Electron collision frequency, ionospheric G factor and the electron energy loss rate parameter in the ionosphere
(1970) V.N. Sharma
Considering the rotational excitations of O2 and N2 an expression for the ionospheric G factor for air has been derived. In view of recent laboratory measurements an expression for v mhas boon obtained and electron collision frequency profilehas been constructed with the help of pressure data. With these parameters the electron energy loss parameter (Gν/N) air has been calculated which compares well with previous results. It is concluded that the contribution of the rotational excitation of O2 to the electron energy lossrate parameter is significant for the free electrons with small energies specially when the electron gas temperature Te is below 290°K. © 1970, Taylor & Fancis Group, LLC.
Electron energy transport coefficients in weakly ionized plasmas: Earth’s lower ionosphere
(1971) V.N. Sharma
The height profiles for the electron energy transport coefficients such as thermal conductivity, electrical conductivity and diffusion coefficient are obtained considering the lower ionosphere as a weakly plasma region. Assuming the velocity independent average electron-neutral collision frequency. i.e. V(υ) = v¯, the different profiles, corresponding to four average electron density height profiles for the quiet and undisturbed lower ionosphere, are drawn. Their comparison shows that the dependence of these coefficients on temperature. especially in the range E|kT∼ l is not clear. © 1971, Taylor & Francis Group, LLC.
Electronic ionization and recombination coefficients for atmospheric molecules-I. Electron impact ionization cross-sections
(1971) V.N. Sharma; D.N. Tripathi; D.K. Rai
The electron impact ionization cross-sections for some molecular atmospheric species such as N2, O2, H2, NO, CO, and CO2 have been calculated using different classical and semiempirical formulae. The effect of nuclear motion has been included as suggested by Bauer. It is found that the semiempirical formula of Darwin with modified values of the parameters f1 and f2 reproduces the experimental values satisfactory. Cross-sections calculated by using this Darwin formula have been used for the calculation of the ionization and recombination coefficients for an O2 plasma. © 1971.
Environmental impact of agro-based industries a case study of Gorakhpur division (U.P.)
(2009) V.N. Sharma; Ms Manvi
Mushrooming of plenty of small agro-based industries generally neglects the environmental concerns. In the absence of proper waste disposal functioning, these industries practice unsafe dumping of hazardous waste in open areas, which are degrading the environment. But, the impacts of agro-based industries on the environment have been under the recycling capacity of the ecosystem, because pollutants caused by them are decentralized due to their decentralized as well as diversified nature. The trend of such impacts is also prevailing in Gorakhpur division except sugar industry (the only big industry), which is causing environmental problems in their localities. This paper assesses the impact of agro-based industries on local ecology through empirical survey.
Variation with electron velocity powers of electron collision frequency and energy transport coefficients in weakly ionised plasmas: Earth’s lower ionosphere
(1972) V.N. Sharma
Correction factors inking into account the variation of the electron–neutral collision frequency with different powers of electron velocity have been applied to calculate the different height profiles for various electron energy transport coefficients such as diffusion coefficient, electrical conductivity and thermal conductivity. Results are discussed in the light of simple gas kinetic model rules which have been shown to break down in the presence of central interaction between electron and neutrals (i.e. in the Earth’s lower ionosphere). Also, assuming the electron energy transport due only to a difference in electron and neutral gas temperatures, height profiles for effective heat flux have been obtained corresponding to different values of ▿ Te. These profiles, on comparison with one another and also with the height profile for the ionospheric G factor, show clearly no transport of electron energy in the Earth’s lower ionosphere due to thermal conduction. © 1972 Taylor and Francis Group, LLC.
