Objectives: Aberrant driving behaviours among bus drivers cause serious concerns to safety on the road. The present study aimed to measure the effects of driver characteristics on aberrant and positive driving behaviours among bus drivers and to group drivers accordingly. The study was carried out among bus drivers of the government-owned road transport corporation in Kerala, India.

In this study, we investigate the low-energy electron (<20 eV) scattering cross sections for the linear ethyl amine and propyl amine using the R-matrix approach. A theoretical study is conducted, covering various cross sections such as elastic, symmetry-wise elastic, differential, momentum transfer, and electronic excitation. We obtained the ionization cross section using the CSP-ic and BEB methodologies.

Detailed theoretical investigations on structural, spectroscopic and electron scattering cross sections of glycolaldehyde, the first ever detected sugar in space are reported in this work. Spectroscopic calculations are performed on the ground and excited states of glycolaldehyde using density functional theory (DFT) and time-dependent density functional theory (TDDFT), respectively. The optimized geometrical parameters and vibrational spectrum are in good agreement with the earlier reported work.

This study presents the results of electron scattering calculations on a biologically important molecule, imidazole, using the UK molecular -matrix method. The -matrix calculations are performed using SE, SEP, and CC models, and the resonance detected in the present SEP model is found to be in better agreement with available experimental data than previous theoretical data. The study also reports an inelastic scattering cross section, which comprises dissociative electron attachment (DEA), excitation, and ionization cross section, for the first time.

Background: Linear odontometry is customarily used in gender determination which can pose difficulties in cases of tooth decay, attrition since they mainly involve the proximal surfaces.

Objectives: The present cross-sectional observation study, estimated the efficacy of alternative measurements, that is, diagonal measurements and cervical measurements in gender determination in comparison to routine odontometry.

Material And Methods: A total of 200 dental cast models (upper and lower) of 100 individuals (50 male and 50 female) from Maharashtra state were included.
