Analytics and Implications of Services Sector Growth in Indian Economy

Given the magnitude of services growth and its inter-linkages with other sectors of the economy, it is important to understand the impact of services sector on other macro-economic variables. The present paper attempts to identify some of the critical issues in India’s services-led growth and tests certain hypotheses that are currently in debate. These relate to: (a) whether the robust growth of the services sector has added a dimension of stability to India's GDP growth; (b) whether there has been a growing complementarity between services and industrial sectors of the economy; (c) whether like other commodity-producing sectors, the services sector also experienced 'jobless' growth; (d) whether the imposition of services tax has boosted the Indian Government’s efforts at mobilising more resources; and (e) whether high growth of services sector in India had an inflationary impact on the economy. Our analysis found the first four hypotheses to hold true. In respect of the last hypothesis, in contrast to the expectations that high services sector growth has an inflationary impact on the economy, we found that the rising share of services sector in GDP has not contributed to inflation in the Indian economy.Services; Industry; Tax; Employment; Inflation

Screening of certain Ayurvedic plants extracts against E. turcicum

The use of chemicals against pathogens is environmentally dangerous, so use of natural inhibitors for disease management is needed. In this work we screen botanical extracts from ayurvedic plants for their antifungal properties against economically important plant fungal pathogen. As a test fungal pathogen, we select E. turcicum, a potent fungal pathogen responsible for Northern leaf corn blight of Maize. This fungal pathogen was challenged by the leaf extract prepared from certain Ayurvedic plants and these observations have shown a promising future in biocontrol of fungus by using such environmentally friendly
antifungal agents

The Scattering amplitude for Rationally extended shape invariant Eckart potentials

We consider the rationally extended exactly solvable Eckart potentials which exhibit extended shape invariance property. These potentials are isospectral to the conventional Eckart potential. The scattering amplitude for these rationally ex- tended potentials is calculated analytically for the generalized mth (m = 1, 2, 3, ...) case by considering the asymptotic behavior of the scattering state wave functions which are written in terms of some new polynomials related to the Jacobi polyno- mials. As expected, in the m = 0 limit, this scattering amplitude goes over to the scattering amplitude for the conventional Eckart potential.Comment: 8 pages. Latex, No fi

PILE SETTLEMENT INDUCED FROM SOIL MOVEMENT DUE TO BREAKDOWN OF RETAINING WALL

Very few studies measured the settlement of retaining wall supported piles foundation under a soil movement. This study explores the pile settlement induced from the sudden breakdown of a closely located retaining wall using a small-scale experimental model. Various factors affect the pile settlement, but the influence of the embedment ratio of the pile and collapsed height of the retaining wall is relatively more visible. The induced settlement decreases with pile embedment depth and increases with the collapsed height of the retaining wall. The pile settlement initially increases at a higher rate with an increase in the collapsed height to a certain extent, beyond which, becomes relatively less observable. Pile group settlement reduces with the increase in spacing and the number of piles in longer piles. However, opposite trends have been observed in piles with a smaller embedment ratio. The settlement reduces logarithmically with the increase in the distance between piles and the retaining wall. Pile groups with small embedment ratio are severely more affected by the breakdown of the retaining wall than the piles of a large embedment ratio. Pile groups placed parallel to the retaining wall are more affected than those placed orthogonally

Velocity Distribution of Driven Inelastic One-component Maxwell gas

The nature of the velocity distribution of a driven granular gas, though well studied, is unknown as to whether it is universal or not, and if universal what it is. We determine the tails of the steady state velocity distribution of a driven inelastic Maxwell gas, which is a simple model of a granular gas where the rate of collision between particles is independent of the separation as well as the relative velocity. We show that the steady state velocity distribution is non-universal and depends strongly on the nature of driving. The asymptotic behavior of the velocity distribution are shown to be identical to that of a non-interacting model where the collisions between particles are ignored. For diffusive driving, where collisions with the wall are modelled by an additive noise, the tails of the velocity distribution is universal only if the noise distribution decays faster than exponential.Comment: 8 pages, 6 figure
