Effect of vehicular vibrations on L-4 lumbar vertebrae - A finite element study.

Lower Back Pain (LBP) is a global health issue, with increasing prevalence, partly attributed to vehicular vibrations experienced by motorcyclists. The L4 lumbar vertebra is responsible for greater mobility and flexibility of the body, but also is the most crucial body element affected by vehicular vibrations. Anthropometric properties, types of speed humps, and vehicle types are the critical variables that impact bone health during riding, need to be studied.

Effectiveness of multi-disciplinary structured training program on mentoring and mental well-being for officers and instructors in the Indian Air Force.

Background: The military environment is characterized by unpredictable situations, intensive training, demanding workload, and job-associated stressors, which make it highly stressful. Mentorship and mental well-being training could be beneficial to both officers and the new adolescent recruits of the Indian Air Force (IAF).

Aim: This study aimed at evaluating the effect of a multi-disciplinary structured training on mentoring and mental well-being among officers and instructors in the IAF.

Perusal on the role of DMF solvent and hydrogen bonding in the formation of 1D polymeric chains in mixed ligand Ni(II) complex as an anticancer agent: a computational approach.

A novel mixed ligand Ni(II) metal complex has been investigated for the modification in structural conformation, coordination bond, and noncovalent interactions. The novel Ni(II) metal complex [Ni(TFPB)(1,10-Ph)(DMF)] has been synthesized and structurally characterized, which featured six coordination with three bidentate ligands connected through oxygen and nitrogen atoms. The single-crystal X-ray analysis showed that the compound possessed octahedral geometry and C-H…F, C-H…O, and π…π intermolecular interactions resulting in the formation of supramolecular architecture contributed significantly towards the crystal packing and molecular stability.

Humidity sensing performance of hybrid nanorods of polyaniline-Yttrium oxide composite prepared by mechanical mixing method.

In this work, polyaniline (PANI) synthesized by in-situ polymerization was mechanically mixed with different feeding mass ratios of YO to form four Polyaniline/Yttrium oxide (PYO) composites. Among them, the PYO-4 composite acquiring nanorod structure with high aspect ratio confirmed from its TEM image and consequent maximum enhancement in its humidity sensing response discussed in comparison with those of PANI and other composites. The interaction of PANI with YO in the composite confirmed from FTIR studies.

Enhancing humidity sensing performance of polyaniline/water soluble graphene oxide composite.

The humidity sensing performance of Polyaniline/Water soluble graphene oxide [PWGO] composites have been presented in this work. Various mass ratios of Water soluble graphene oxide [WGO] were mechanically mixed with Polyaniline [PANI] prepared by in-situ polymerization process to form PANI / WGO composites. For the purpose of humidity sensing studies, the samples were structurally characterized by FTIR, Raman, XRD, SEM and TEM techniques and comparatively analyzed.
