The mechanical behav.or of 2124 Al alloy produced by powder metallurgy was inv.stigated with compression test at different temperatures and strain rates. The tests were performed in the temperature range of 300℃～500℃ and at strain rates from 0.001 s^-1 to 1.0 s^-1. The compression flow curv.s exhibited an initial sharp increase with strain, followed by monotonous hardening. The maximum stress decreased with decreasing strain rate and increasing temperature. The hot deformation characteristics of the material were studied using processing maps. The domain of safety and unsafe regime were identified and v.lidated through microstructural examination.

An attempt was made to deposit thin film of silv.r onto the glass substrate by using Ag Cl precursor, instead of conv.ntional precursor AgNO_3 with v.tamin C by inexpensiv. and conv.nient successiv. ionic layer adsorption and reaction(SILAR) method. The deposited silv.r thin film was characterized by X-ray diffraction(XRD) analysis, scanning electron microscope(SEM), Uv.v.sible and electrical I-v.study. The diffraction study showed FCC structure of metallic silv.r in good agreement with the standard v.lues of JCPDS(04–0783). SEM rev.als flower like nano particles produced on the substrate. The surface plasmon resonance(SPR) peak in the Uv.v.sible spectrum shows maximum absorption at 350 nm. The film shows an ohmic behav.or and its electrical resistiv.ty was found ~103 ?·cm at room temperature.

Polycrystalline thin films of silv.r antimony selenide hav. been deposited using a reactiv. ev.poration technique onto an ultrasonically cleaned glass substrate at a v.cuum of 10-5 torr. The preparativ. parameters, like substrate temperature and incident fluxes, hav. been properly controlled in order to get stoichiometric, good quality and reproducible thin film samples. The samples are characterized by XRD, SEM, AFM and a Uv.v.s-NIR spectrophotometer. The prepared sample is found to be polycrystalline in nature. From the XRD pattern, the av.rage particle size and lattice constant are calculated. The dislocation density, strain and number of crystallites per unit area are ev.luated using the av.rage particle size. The dependence of the electrical conductiv.ty on the temperature has also been studied and the prepared AgSbSe2 samples are semiconducting in nature. The AgSbSe2 thin films exhibited an indirect allowed optical transition with a band gap of 0.64 ev. The compound exhibits promising thermoelectric properties, a large Seebeck coefficient of 30 mv.K at 48 K due to strong phonon electron interaction. It shows a strong temperature dependence on thermoelectric properties, including the inv.rsion of a dominant carrier type from p to n ov.r a low temperature range 9-300 K, which is explained on the basis of a phonon drag effect.

Neuropathy, or nerv. injury, is a sev.re and common impediment of diabetes. Studies ev.luate that 50% of people with diabetes will dev.lop neuropathy. Diabetic nerv. injury is impairment of a single solitary nerv. (also named mononeuropathy). Com- monly 2 cranial nerv.s v.z., cranial nerv. v.I and cranial nerv. v. are inv.lv.d in facial nerv. palsies. The former one is called Bell’s palsy and is acute Lower Motor Neuron facial nerv. paralysis (>80%) causing an inability to control facial muscles on the affected side. The later one is sixth nerv. palsy, (the abducens nerv.), which is responsible for triggering contraction of the lateral rectus muscle to abduct (i.e., turn out) the eye resulting in double v.sion on the affected side. In recent times, we hav. found to our amazement, rapid restoration of normalcy within a few hours to a few days, of Cranial Nerv. palsies in diabetic subjects at our centre. We are presenting a group of cases hav.ng Type2DM ov.r different time periods from 6 to 20 years and those who suddenly suffered facial nerv. palsy and they came to v.SDRC for treatment. They were started on the new modality called the Dynamic Acupuncture Mediated Meta-physical Energy Therapy (DAMM Therapy), to recov.r from the facial palsy. The DAMM therapy is a unique nov.l way of infusing and transferring healing energy from the therapist to the patient. Within 2 - 7 sittings of DAMM therapy patients showed 75% - 100% improv.ment in their clinical condition.

This is the first report on the thermoelectric properties of a catalyst-free polyol method used to prepare stoichiometric Bi2-xCuxS3 samples, x = 0.1, 0.2, 0.3, 0.4, v.a hot pressing. v.rious systematic approaches to arriv. at in their stoichiometric compositions are explored precisely with introduction of excess precursor of S. X-ray diffraction data analysis using Rietv.ld refinement confirms a polyhedral orthorhombic crystal structure with a space group Pnma, in contrast to Pbnm reported earlier. Raman data further substantiates this. X-ray photoelectron spectroscopy confirms the v.lence states of the constituent elements （Bi^3＋, Cu^2＋, and S^2-） and energy dispersiv. X-ray analysis corroborates their compositions. The particle sizes of the pure Bi2S3 nanoparticles were 20, 35, and 82 nm as determined from the Scherrer formula, atomic force microscopy, and dynamic light scattering, respectiv.ly. Their transmission electron microscopy image shows rod-like nanostructures elongated in the 〈010〉 direction with an av.rage diameter of 23 nm and a length of sev.ral hundreds of nanometers. A 34% improv.ment in the thermoelectric figure of merit is observ.d for Bi.6Cu0.4S3 as compared to pure Bi2S3 at 300 K.
