ALTERED TEMPERATURE THRESHOLD ASSESSMENT IN DIABETIC PATIENTS SUFFERING FROM PERIPHERAL NEUROPATHY
This project describes the assessment of the altered temperature sensation in the type 2 diabetic patients suffering from peripheral neuropathy. Peltier crystal is used as a temperature threshold determining tool. Its temperature is altered and this is introduced on the site of examination of the body like palm, foot etc. Tests are conducted for both hot and cold cases. The thermograph (temp v/s time plot) is plotted using digital values obtained by the electric circuitry in any of the software platforms. Average values of 3 or more tests yield a better distinctive value of the altered temperature threshold. [1
Linear and Nonlinear Optical Properties of Mn doped Benzimidazole Thin Films
In the present work, the Mn doped benzimidazole (BMZ) thin films were
prepared by simple chemical bath deposition technique. The material was
directly deposited as thin film on glass substrates and the metal concentration
in the solution was varied in weight percentage in order to investigate the
dopant effect on the properties of thin films. Similarly, the Mn doped BMZ
films were deposited in different solution temperature to study the effect of
deposition temperature on the properties of thin films. The PXRD and FT-IR
spectroscopy are used to study the structural and the presence of functional
groups in the BMZ medium. Depending upon the solution temperature, thickness of
the films varying from 0.6 to 1.2 {\mu}m and the optical transparency of the
samples increases with the increasing temperature up to 50 {\deg}C. Second
Harmonic Generation (SHG) efficiency of the films is measured for all the
films. Third order nonlinear optical properties of the films were analyzed
using Z-scan technique. The experimental results show that Mn doped BMZ films
exhibits saturation absorption and negative nonlinearity.Comment: This has been presented in DAE 58th Solid State Symposium held at
Thapar University, Patiala, Punjab, India. Will be published in AIP

Assessment of Mass-Transfer Effects and Elementary Reaction Scheme for Catalytic Reactors
Catalytic combustion is carried out in a tubular reactor of radius in the order of millimeters and a
length of around 10 centimeters in presence of catalysts Rhodium and Platinum. For mass transfer
coe�cient calculation in the modeling of mass transfer between the bulk of the
uid to the surface,
correlations developed by Tronconi and Forzatti(1992) are used. The results shows that the assump-
tion stating both the bulk concentration and concentration at the surface are same, deviates from
the actual scenario. The combustion is actually slow than what PFR predicts when we observed
the mass transfer limited catalytic combustion. A discrepancy is observed with the mechanism of
methane partial combustion in the presence of Rhodium catalyst in terms of the concentrations
of CO2 and H2O mole fractions, the mechanism gives more CO2 and H2O than the equilibrium
composition
