BANKING SECTOR REFORMS AND EQUITY - A SUB-REGIONAL ANALYSIS IN ANDHRA PRADESH

The changes in government policies are continuous to correct the ill effects of its earlier policies. In this study an attempt is made to examine the equity aspect due to reforms in the banking sector at sub-regional level in the state of Andhra Pradesh covering the period 1985 to 2004. The analysis indicates that the share of rural areas in number of branches, number of accounts, deposits and credit declined during pre and post liberalisation periods. Despite declining shares in most of the parameters especially those of credit and deposits, there is positive growth in both the periods. However, the growth of these parameters is more in urban areas. The distribution of credit among the sectors indicates that the share of agricultural sector in accounts and credit declined during pre and post liberalisation periods. The share of agricultural credit declined in all the regions during pre and post liberalisation periods. This is true with respect to credit and number of credit accounts. In the case of other sectors, the share in accounts and credit increased in both the periods. Though, the share in the agriculture sector declined in all the regions, per account credit increased in all the regions during both the periods. It may be concluded that liberalisation has increased inequalities. But the rate of increase in inequalities is arrested to a certain extent in the recent past. But if one looks at the growth of credit given to different sectors and growth of credit in rural and urban areas, one may not come to this kind of conclusion.Banking Sector Reforms, Equity, Andhra Pradesh

The role of shear in dissipative gravitational collapse

In this paper we investigate the physics of a radiating star undergoing dissipative collapse in the form of a radial heat flux. Our treatment clearly demonstrates how the presence of shear affects the collapse process; we are in a position to contrast the physical features of the collapsing sphere in the presence of shear with the shear-free case. By employing a causal heat transport equation of the Maxwell-Cattaneo form we show that the shear leads to an enhancement of the core temperature thus emphasizing that relaxational effects cannot be ignored when the star leaves hydrostatic equilibrium.Comment: 15 pages, To appear in Int.

Superconductivity in doped FeTe1-xSx (x= 0.00 to 0.25) single crystals

We report self flux growth and characterization of FeTe1-xSx (x= 0.00 to 0.25) single crystal series. Surface X-ray diffraction (XRD) exhibited crystalline nature with growth in (00l) plane. Micro-structural (electron microscopy) images of representative crystals showed the slab-like morphology and near stoichiometric composition. Powder XRD analysis (Rietveld) of single crystals exhibited tetragonal structure with P4/nmm space group and decreasing a and c lattice parameters with increase in x. Electrical resistivity measurements (R-T) showed superconductivity with Tconset at 9.5K and 8.5K for x =0.10 and x =0.25 respectively. The un-doped crystal exhibited known step like anomaly at around 70K. Upper critical field Hc2(0), as calculated from magneto transport for x =0.25 crystal is around 60Tesla and 45Tesla in H//ab and H//c directions. Thermal activation energy [U0(H)] calculated for x =0.10 and 0.25 crystals followed weak power law, indicating single vortex pinning at low fields. Mossbauer spectra for FeTe1-xSx crystals at 300K and 5K are compared with non superconducting FeTe. Both quadrupole splitting (QS) and isomer shift (IS) for S doped crystals were found to decrease. Also at 5K the hyperfine field for x =0.10 superconducting crystal is decreased substantially from 10.6Tesla (FeTe) to 7.2Tesla. For x =0.25 crystal, though small quantity of un-reacted Fe is visible at room temperature, but unlike x =0.10, the low temperature (5K) ordered FeTe hyperfine field is nearly zero.Comment: 20 Pages Text + Figs: Accepted Mat.
