Opis:: During the growth of cadmium iodide crystals from solution, it has been observed that sometimes the crystal suddenly rotates. Probably, the convection currents are providing the force for the rotation. Mathematically, this force can be estimated and it must be greater than the van-der Walls force acting between adjacent sandwiches of cadmium iodide and can give rise to polytypic phase transformations. Further, studies of vacancies and the density measurements of various polytypes can help in understanding the phenomenon of polytypism better.

Opis:: Thermal convection of a rotating dielectric micropolar fluid layer under the action of an electric field and temperature gradient has been investigated. The dispersion relation has been derived using normal mode analysis. The effects of the electric Rayleigh number, micropolar viscosity, Taylor number and Prandtl number on stability and over stability criteria are discussed. It is found that rotation postpones the instability in the fluid layer, while the Prandtl number and rotation both have a stabilizing effect. It is also observed that the micropolar fluid additives have a stabilizing effect, whereas the electric field has a destabilizing effect on the onset of convection stability.

Opis:: The photocatalytic, sonolytic and sonophotocatalytic degradation of 4-chloro-2-nitrophenol (4C2NP) using heterogeneous (TiO2) was investigated in this study. Experiments were performed in slurry mode with artificial UV 125 watt medium pressure mercury lamp coupled with ultrasound (100 W, 33+3 KHz) for sonication of the slurry. The degradation of compound was studied in terms of first order kinetics. The catalyst concentration was optimized at 1.5 gL-1, pH at 7 and oxidant concentration at 1.5 gL-1. The results obtained were quite appreciable as 80% degradation was obtained for photocatalytic treatment in 120 minutes whereas, ultrasound imparting synergistic effect as degradation achieved 96% increase in 90 minutes during sonophotocatalysis. The degradation follows the trend sonophotocatalysis > photocatalysis > sonocatalytic > sonolysis. The results of sonophotocatalytic degradation of pharmaceutical compound showed that it could be used as efficient and environmentally friendly technique for the complete degradation of recalcitrant organic pollutants which will increase the chances for the reuse of wastewater.

Opis:: Background. The second wave of Novel Coronavirus disease (COVID-19, SARS-CoV-2) is proving more disastrous than the first because of the new mutant stains. Under these circumstances, vaccination is the only effective solution that can save millions of lives across the globe. Objectives. The present study was conducted to assess the attitude and acceptance/willingness of health care professionals (medical and dental) towards COVID-19 vaccine. Materials and Methods. An online questionnaire survey was conducted among medical and dental professionals working in different hospitals of two states of India. A total of 520 subjects constituted the final sample size. A self-constructed questionnaire (divided into 2 parts) containing 12 questions was administered to obtain information from the subjects regarding their attitude and willingness towards COVID 19 vaccine. Statistical analysis was done using chi-square test and multiple liner regression analysis. Odds ratio with 95% CI were also generated. Statistical significance was set at p≤0.05. Results. Majority of the subjects (67% of dental and 73% of medical) had full confidence on the effectiveness of COVID-19 vaccine. Willingness to get vaccinated was shown by 63% of subjects and 65% had positive attitude towards vaccine. Some subjects (45.5% dental and 48.4% medical) showed concern regarding unforeseen effects of the vaccine. Willingness to get vaccinated was 3.45 higher in subjects who were involved in COVID duties. Subjects giving less preference to natural immunity over vaccine showed more willingness (OR: 2.98) towards getting the vaccine. Conclusion. The findings of the study showed that acceptance and attitude of subjects regarding COVID 19 vaccine was suboptimal as there were various factors which contributed towards subjects’ hesitancy to get vaccinated. There is an utmost need to address various issues regarding vaccine safety to promote high uptake.
