Its merits over the stereographic method are considered. In association with this the hardness anisotropy of InBi<sub>1-x</sub>Se<sub>x</sub> and InBi<sub>1-x</sub>Sb<sub>x</sub> single crystals has been studied and the analysis shows that minimum values of hardness are obtained. The rotation of indenter with respect to its initial setting with maximum values in between them and the results are discussed in details. Dimpal Shah S. M. Vyas G. R. Pandya M. P. Jani K. R.

The structure and microstructure of the samples has been characterized using X-ray diffraction, infrared spectroscopy (Fourier transformed infrared spectroscopy) and Scanning electron microscopy (SEM). Thermal properties of the samples are studied by means of Differential Scanning Calorimetry (DSC) revealed that the glass transition temperature increases for the composites [PVA + 10% SCN (T<sub>g</sub> = 109°C)] compared to pure PVA (T<sub>g</sub> = 97°C) samples. The dielectric characterization has been studied by means of impedance gain-phase analyzer. It is concluded that addition of 50% SCN lead to significant advantage on the dielectric properties of Polyvinyl alcohol polymers. Observed changes in the dielectric dispersion at high temperatures are essentially linked to the glass transition temperature (T<sub>g</sub>) rather than due to lattice based dielectric dispersion.

The lithium-basedceramics have shown good irradiation behavior and excellent tritium release characteristics. Individual materialsperformance will depend upon the actual application, namely, pebble bed versus pellet concept, higher versus lower cooling temperature, etc. There are different methods: extrusion/spheronization, melting/spraying, gelcasting, wet method.

Portions of these blend films are exposed to swift heavy O<sup>7+</sup> ion radiations. Changes taking place in thermal, electrical and relaxation properties at various LiCF<sub>3</sub>SO<sub>3</sub> salt concentrations of all the blend specimens prior and after irradiation are thoroughly investigated. Relaxation time τ and Kohlrausch-William-Watt's exponent β which throw light on the relaxation dynamics of the blend samples are calculated using modulus formalism. For both, prior as well as after irradiation, all these properties are found to be optimum at 9 wt% of salt concentration. However, irradiation has led to a significant enhancement in these properties of the blends at all salt concentrations. Scaling of modulus is carried out to analyse time-composition superposition principle. Relaxation dynamics is observed to be independent of salt concentration in cases of both, pristine and irradiated blends. Prajakta Joge D. K. Kanchan Poonam Sharma Manish Jayswal D. K.

These include thermogravimetry (TGA), derivative thermogravimetry (DTG) and differential thermal analysis (DTA). The thermogravimetry data allowed the determination of activation energy and frequency factor. The relative thermal stabilities of the studied compounds have been evaluates in terms of composition (x) and follow the order 0.25&gt;0.50&gt;0.75. The DTA pattern shows a strong endothermic transition around 550K. The different kinetic parameters: entropy, enthalpy and Gibbs free energy were evaluated using Piloyan-Novikova and Coats-Redfern relations. Priyanka Desai D. D. Patel A. R.

Prospective observational study of all patients admitted to the ICU complex of SRMSIMS between1st January to 31<sup>st</sup> April 2016 for a minimum period of 5 days. Patients will be observed for abnormalities of the lid , conjunctiva, cornea and tear film by diffuse illumination aided by Schirmer's Test, corneal and conjunctival staining and conjunctival swab when required. Other factors like consciousness, use of a ventilator, preexisting comorbidities shall also be noted. Patients will be observed on Day1, 5, 6, and so on. 60 eyes of 30 patients were examined . In mechanically ventilated patients , 36 eyes (60%) had conjunctival hyperemia which resolved upon intervention which included antibiotics and lubricants . 18 eyes (9%) had conjunctival discharge which resolved upon intervention. 12 eyes (20%) were stain positive. The critically ill often develop ocular surface disorders, especially when sedated and immobilized. A close relationship was observed between these conditions and the inability to close one's eyes. The presence of ocular surface disease was closely correlated with the degree of lagophthalmos, which in turn was closely related to the depth of sedation or paralysis. S. Singh N. Mehrotra L.

In the present study, various amount of lithium doped KDP single crystals were grown by slow solvent evaporation method. For doping lithium chloride was mixed with KDP solution in 1, 3 and 5 weight percent. The grown crystals were transparent and prismatic in nature with maximum dimension of 5 cm x 1.5 cm x 0.5 cm. The presence of lithium was detected by flame test. The powder XRD study indicated single phase nature of the grown crystals and the doping caused minor change in the KDP structure, which was confirmed by the minor change in unit cell parameters. From FTIR study the functional groups like O-H, P-O, P-OH were identified but no major change due to lithium doping was found. The dielectric study was carried out in the range from 10 kHz to 10MHz indicated sharp decrease in dielectric constant with frequency of applied field after 70 kHz. The AC conductivity increased with increase of frequency. The dielectric constant was found to be sensitive to doping in KDP. Mitesh B. Solanki Jaydeep H. Joshi Poorvesh M. Vyas Mihir J.

In the present investigation 0.01N Ammonium Molybdate doped ZTS crystal was grownusing single diffusion gel growthtechnique which has an advantage over normally employed solution growth method, in terms of controlled nucleation and hence better perfection. A significant morphological alteration was observed due to doping. The functional groups of pure and doped ZTS crystals were recorded and identified using Fourier Transform Infrared Spectroscopic (FTIR) analysis. A study on hardness variation due to doping was conducted using Vickers' Hardness Tests. The increase in hardness observed can be assigned to the impurity hardening effect as found to increased due to effect of dopant. The results obtained are elaborated and discussed in the paper.
