The present study attempts to investigate the most preferred leadership behaviors among the transformational and transactional leadership styles and its impact on Employees' organizational commitment in BHEL. For this study 158 sample respondents had been drawn out from among the Senior Engineers and the Trainee Engineers group. Statistical tools like One-Way ANOVA, Correlation analysis and Regression analysis were used to find out whether there was any significant difference in the leadership styles based on the position and pay and to find out the degree of association between preferred leadership styles and organizational commitment. The results of the study concluded that while the positional identity of the respondent had some significant impact on leadership style perception and organizational commitment, salary did not seem to make a difference from among the sample respondents.

Defence personnel face multiple threats from different quarters, like terrorist groups and rogue nations, who own not only advanced lethal weapons but also chemical and biological warfare weapons. The present day protective clothing system used by the defence sector is vulnerable to modern weapons and also have some inherent weaknesses like high cost, bulkiness and discomfort in wearing. Nanotechnology-based materials offer a promising future in this area due to their extraordinary physical, chemical, mechanical, and electrical properties at nano-level. This paper outlines the various developments related to the application of nanotechnology in producing lightweight and comfortable protective clothing for the military personnel and also some new developments like sensor, energy storage, conductivity, and decontaminant fabrics.

For the first time, the effect of ultrasound in the diagnostic frequency range of 1-10 MHz on the nucleation and growth characteristics of glycine has been explored. The investigation employing the ultrasonic interferometer was carried out at a constant insonation time over a wide range of relative supersaturation from σ=-0.09 to 0.76 in the solution. Ultrasound promotes only α nucleation and completely inhibits both the β and γ nucleation in the system. The propagation of ultrasound assisted mass transport facilitates nucleation even at very low supersaturation levels in the solution. The presence of ultrasound exhibits a profound effect on nucleation and growth characteristics in terms of decrease in induction period, increase in nucleation rate and decrease in crystal size than its absence in the solution. With an increase in the frequency of ultrasound, a further decrease in induction period, increase in nucleation rate and decrease in the size of the crystal is noticed even at the same relative supersaturation levels. The increase in the nucleation rate explains the combined dominating effects of both the ultrasound frequency and the supersaturation in the solution. Analytically, the nucleation parameters of the nucleated polymorph have been deduced at different ultrasonic frequencies based on the classical nucleation theory and correlations with the experimental results have been obtained. Structural affirmation of the nucleated polymorph has been ascertained by powder X-ray diffraction.
