This paper describes an analytical model for bulk electron mobility in strained-Si layers as a function of strain. Phonon scattering, columbic scattering and surface roughness scattering are included to analyze the full mobility model. Analytical explicit calculations of all of the parameters to accurately estimate the electron mobility have been made. The results predict an increase in the electron mobility with the application of biaxial strain as also predicted from the basic theory of strain physics of metal oxide semiconductor （MOS） devices. The results have also been compared with numerically reported results and show good agreement.

Host plants of domesticated silkworms in tropical countries are attacked by an array of insect pests, disease pathogens and nematodes. In order to reduce resulting plant damage, chemicals have been extensively used. In recent years, products extracted/isolated from 47 plant species have been tested as replacements for or to minimize the use of hazardous chemicals. Bioefficacy of the extract in water or chemical solvent, crude seed/leaf oil, and cake is discussed, and integrated management of major and occasional pests and plant diseases is proposed in sericultural plants in order to produce chemical-free foliage.

A simple synthesis of medicinally important cis-2-methyl-4-azapan-2-one-1,2,3,4-tetrahydroquinolines/cis-9- （2-methyl-l,2,3,4-tetrahydroquinolin-4-yl）-9H-carbazole was reported. Multicomponent one pot synthesis with ani- lines and N-vinylcaprolactam/N-vinyl carbazole via imino Diels-Alder reaction by using antimony trichloride as catalyst and acetonitrile as solvent was employed. NMR technique （2D） was used to study the regio- and stereo- chemistry of newly synthesized compounds. The cis diastereo-selectivity of the products was predicted by COSY and NOESY studies.

Glass fi ber reinforced gypsum(GFRG) wall panels are prefabricated panels with hollow cores, originally developed in Australia and subsequently adopted by india and China for use in buildings. This paper discusses identifi cation and calibration of a suitable hysteretic model for GFRG wall panels fi lled with reinforced concrete. As considerable pinching was observed in the experimental results, a suitable hysteretic model with pinched hysteretic rule is used to conduct a series of quasi-static as inelastic hysteretic response analyses of GFRG panels with two different widths. The calibration of the pinching model parameters was carried out to approximately match the simulated and experimental responses up to 80% of the peak load in the post peak region. Interestingly, the same values of various parameters(energy dissipation and pinching related parameters) were obtained for all fi ve test specimens.

A fluid dynamic model of a bubbling fluidized-bed coal gasifier is presented considering two-phase theory of fluidization. The effects of the gasifier temperature and bed particle size on the hydrodynamic char- acteristics of both the bubble and emulsion phases of the gasifier bed are studied. The bubble diameter, bubble velocity, and bubble area fraction are evaluated for the bubble phase, whereas the gas velocity and porosity are studied for the emulsion phase, along the height of the bed. Finally, the rate of inter-phase gas exchange from the emulsion phase to bubble phase is calculated under different operating conditions.
