The shale deposits of Damodar Valley have received great attention since preliminary studies indicate their potential for shale gas. However, fundamental information allied to shale gas re- servoir characteristics are still rare in India, as exploration is in the primary stage. In this study, Ba- rakar shale beds of eastern part of Jharia Basin are evaluated for gas reservoir characteristics. It is evident that Barakar shales are carbonaceous, silty, contains sub-angular flecks of quartz and mica, irregular hair-line fractures and showing lithological variations along the bedding planes, signifying terrestrial-fluviatile deposits under reducing environment. The values of TOC varies from 1.21 wt.% to 17.32 wt.%, indicating good source rock potentiality. The vitrinite, liptinite, inertinite and mineral matter ranging from 0.28 vol.% to 12.98 vol.%, 0.17 vol.% to 3.23 vol.%, 0.23 vol.% to 9.05 vol.%, and 74.74 vol.% to 99.10 vol.%, respectively. The ternary facies plot of maceral composition substan- tiated that Barakar shales are vitrinite rich and placed in the thermal-dry gas prone region. The low values of the surface area determined following different methods point towards low methane storage capacity, this is because of diagenesis and alterations of potash feldspar responsible for pore blocking effect. The pore size distribution signifying the micro to mesoporous nature, while Type II sorption curve with the H2 type of hysteresis pattern, specifies the heterogeneity in pore structure mainly combined-slit and bottle neck pores.

A simple statistical mechanical theory based on compound formation model (compound Aμ Bv formed by the preferential arrangement of A and B constituent atoms of the alloy AB, μA + νB ≒ Aμ Bv) has been used to investigate the phenomena of compound formation in NaCd liquid alloys through the study of concentration fluctuation in the long wavelength region [Scc(0)] and chemical short range order parameter (α1). The study explains the observed asymmetry successfully and suggest the existence of Cd2Na complex in the melt. The tendency of compound has been found to be weak. A tendency of inversion from segregation to order although very small, has been observed, in NaCd liquid alloys.

Sugar recovery in a factory depends upon regular crushing and quality of varieties besides various other working parameters. Strategies for increased productivity and sugar recovery, varietal improvement can bring out through selection of parents to get maximum gains. These are governed by sugar content, fiber, rind hardness and cane yield. In order to assess the breeding value of different traits including rind hardness, study was undertaken at Sugarcane Research Institute, Shahjahanpur, during 2011-2012. Phenotypic difference and correlations among agronomic characters, basic quality characters and rind hardness in 120 segregating genotypes derived from contrast bi-parental cross (UP9530 × Co86011) of sugarcane cultivar were studied in this experiment. All the traits observed were found statistically significant among the mapping populations. The mean value of rind hardness was 5.91 with a range from 2.08 to 12.10 among 120 segregating population including their parents. Rind hardness (RHD) showed significant positive genotypic correlation with sugar yield-related traits viz;cane weight (CW, r = 0.325), cane yield (CYLD, r = 0.380) and sugar yield (SUYLD, r = 0.248). Significant negative correlation was observed for rind hardness with commercial cane sugar percent (CCS%, r = -0.388), number of millable cane (NMC, r = -0.216), hand refractometer brix %-October (HBR, r = -0.154), Brix% in juice (BR, r = -0.119) and Sucrose% in juice (SUC, r = -0.080). The simple correlation analysis showed that RHD, CW, CYLD and SUYLD showed significant positive correlation for agronomic characters, but for basic quality characters had negative correlations. Result indicated that rind hardness was found to have economically important trait due to showing significant positive and negative correlation with sugar yield and sugar content, respectively. The study also revealed that with the reduction in rind hardness, sugar recovery may increase. Present findings indicated that the rind

＜正＞A tightly coupled fluid-solid dynamics interaction approach has been developed for the efficient prediction of aerodynamic loads on rotor blades in forward flight. The aerodynamic computations are done using a 3-D Navier-Stokes solver modeling the viscous flow over the blade and the near wake. The elastic structural dynamic computations are carried out using a multi-body dynamics approach. The fluid and solid dynamics equations are simultaneously integrated in time, providing a tight coupling between the structural dynamic and fluid dynamic solvers at every time step. A generalized grid motion module has been developed to account for the effects of the blade motion and elastic deformations on the aerodynamics. A free self-induced wake model is used to model the tip vortex effects once the blade tip vortices leave the resolved CFD domain. A four-bladed UH-60A rotor at a high advance ratio has been studied, and the results compared with flight test data.
