Dire need to impart moral education in schools
Full text linkBuilding upon the recent boxer Sushil Kumar case, the author finds the traditional family and social structure failing in its duty to instil morals in the youth, so that the onus falls squarely on schools and a serious implementation of the soon-to-be implemented NEP2020.

The first asymmetric organolithium tetramers with simple ether donor bases
No full textThe donor-free trimethylsilylmethyllithium [LiCH(2)SiMe(3)](6) hexameric aggregate is for the first time broken up by simple ether donors such as diethyl ether (Et(2)O) and tert-butylmethyl ether ((t)BuOMe) to give the unprecedented asymmetric tetramers while the chelating dimethoxyethane (DME) gives the expected dimer
On the reductions of airfoil broadband noise through sinusoidal trailing-edge serrations
No full textThe present study investigates the efficacy of sinusoidal trailing-edge (TE) serrations as a passive means for the reductions of airfoil broadband noise, theoretically and experimentally. Comprehensive parametric studies were conducted to determine the effect of serration amplitudes and wavelengths on the noise reduction performance of a National Advisory Committee for Aeronautics (NACA) airfoil. Initially, the present paper shows the use of the trailing-edge noise (TNO) model for the accurate predictions of the surface pressure spectrum near the TE and hence the far-field noise using the Wiener-Hopf method. The predicted spectra and the noise reduction levels showed good agreement with the measurements for a wide range of frequencies. The present study reveals that the local maximums of the overall noise reductions occur when the transverse turbulence integral length scale is either 1.2 or 0.2 times the serration wavelength, which corresponds to λ/t=0.833 or 5, where λ and t are the serration wavelength and integral length scale. One of the key findings of the paper is that the serration wavelength at which the highest noise reductions occur when the acoustic emissions vary inversely with the modified Strouhal number Sthm [i.e., wsste(ω)/wbl(ω) 1/Sthm] for narrow (i.e., small wavelengths) and wider serrations (i.e., large wavelengths), where wsste and wbl are the acoustic emissions radiated from the serrated and baseline airfoils. Further, the TE serrations are also observed to reduce leading-edge (LE) noise along with the self-noise, which indicates the efficacy of TE serrations in reducing the total far-field noise.</p
