Polycrystalline thin films of CdSe were prepared by the electrochemical method by using CdCl2, EDTA and Na2SeO3 on titanium substrate and the deposition was carried out at different deposition period. The influence of deposition period, towards the photoresponse activiyt of the sample were evaluated. The samples were characterized using X-ray diffractometry

The chisness chester2-whitam3 method has been used to study the propagation of diverging cylindrical hydromagnetic shock waves through a self gravitaing gas in the presence of a magnetic field having only constants axia(HZ0) component, the problem is investigated for strong shock only. Assuming an initial density distribution p0=pirw wher r1 is the density at the axis of symmerty and a constants, the reaction for shock velocity and the shock strength pressure, particle velocity and density have been obtained.

We present a new timer with light senson discharging all disadvanates of earlier one. The newly developed timer circuit use CMOS IC 4060B. We can adjust the different type of time interval using resistance and capacitance coupling in circuit. The aim of the this paper is to present the timer circuit which work on light sensor with musical alarm.

Plantinum electronic when gien anodic or cathodic treatment show attenuation in potential oscillations in the study of Briggs-Rauscher oscillating chemical reaction. Moreover, some electrodes did not even indicate oscillations though the solution was oscillating. Further it was observed that keeping an electode Hydrogen peroxide for a number of days rejuvenates its capacity to sense oscillations. Mechanism of such behabvior is contemplated

The present describes and structural features of some chelates polymers of Azelody bis-p-toyl carbamide (AZBPU) with first transition series metal ions viz Mn(II), Co (II), Ni(II) and Zn(II). The resultig chelate polymers have been characterized on the basis of elemental analysis, electronics spectral and magnetic suscetibility studies. The nature of bonding has been discussed on the basis of IR spectral data. To ascertain there thermal stability a detailed thermal studies was carried out by Freeman-Carol and Sharm-Went worth method.

Carbon fiber rienforced compositeis were prepared using PUI-Epoxy resin as a matrix material and carbon fiber as fibrous material. Similarly, galss fibre reionforced composites were prepared by replacing carbon fibre with glass cloth. Both types of composiites were for mechanical and electrial properties and chemicla resistances. The poly (urea-imide) was preapred by condensation reaction using an equimolar ratio of an amito terminated oligomide with various aliphatic diiscoyanates. The PUIs were characterized by elemental analysis, the number average molecular weith estimation and thermogravimetric analysis. The cure reaction of an epoxy resin with PUI was mointored by dirrerential scanning calorimetric method.

Carbon fiber reinforced composites were prepared using PUI-Epoxy resin as a matrix material and carbon fiber as fibrous material. Similarly, glass fiber reinforced composites were prepared by replacing carbon fiber with glass cloth. Both types of composites were characterized for mechanical and electrical properties and chemical resistances. The poly (urea-imide) was prepared by condensation reaction using an equimolar ratio of an amino terminated oligoimide with various aliphatic diisocyanates. The PUIs were characterized by elemental analysis, the number average molecular weight estimation and thermogravimetric analysis. The cure reaction of an epoxy resin with PUI was monitored by differential scanning calorimetric method.
