The aim of this paper is to describe the measurement system and procedure for amount determination and fast Fourier analysis of inrush current which occurs during switching of unbiased transformer on electric grid. This current can reach high amounts and threaten transformer isolation, other transformers and consumers…

Benzoyl peroxide (BPO) initiated grafting of methyl methacrylate (MMA), 2-hydroxyethyl methacrylate (HEMA) and glycidyl methacrylate (GMA) onto cellulose extracted from pine needles along their binary monomer mixtures with acrylamide (AAm), acrylic acid (AAc) and acrylonitrile (AN) have been reported earlier. Graft co…
A validated RP HPLC method for the estimation of Atazanavir sulphate in capsule dosage form on Egilent TC C18 (2) 250 x 4.6 mm, 5 μ column using mobile phase composition of water: acetonitrile (20:80 v/v) pH adjusted to3. Flow rate was maintained at 1 ml/min at an ambient temperature. Quantification was achieved with…
The surface behavior of a series of SnO 2 (5, 10 and 20 wt.%) -CeO 2 catalyst samples prepared by impregnation method and also pure SnO 2 , CeO 2 , was studied based on the response of the ac electrical conductivity.The electrical measurements were carried out in operando conditions in order to obtain information abou…
The solid complexes of Cu(II), Ni(II), Co(II), Mn(II) and Fe(III) with asymmetrical tetradentate Schiff bases derived from o-phenylenediamine (H2L1)/4-methyl o-phenylenediamine (H2L2), 3-Acetyl-6-methyl-pyran-2,4-dione (Dehydroacetic acid) and 2-hydroxy-1-naphthaldehyde have been synthesized and characterized by eleme…
This study describes the synthesis of Al(2)O(3)/SiC/ZrO(2) functionally graded material (FGM) in bio-implants (artificial joints) by electrophoretic deposition (EPD). A suitable suspension that was based on 2-butanone was applied for the EPD of Al(2)O(3)/SiC/ZrO(2), and a pressureless sintering process was applied as…
As the radon progeny contribute a major part of natural radiation dose to general population, attention has been given to the large scale and long term measurement of radon and its progeny. Recent epidemiological evidence suggests that inhalation of low level radon and its progeny in dwellings may contribute towards t…
The development of deformation structure in the low carbon lath martensite steel was clarified using transmission electron microscopy observation with Kikuchi pattern analysis. The retained austenite films on the martensite lath boundaries transform to high carbon martensite films by light deformation, and the high ca…
\n\t\t\t\t\tCarbon nanotubes (CNTs) are among the strongest known materials. Their potential as nanoscale reinforcement for cementitious materials is significant, with some reported compressive strength increases in excess of 50%. However, there is a great deal of variability in the results obtained, with some researc…
Itraconazole (ITZ) is an orally active, triazole antifungal drug. It is used for the management of local and systemic fungal infections. However, the effectiveness of ITZ is limited due to its poor aqueous solubility and low dissolution rate. In the present study, inclusion complexes of ITZ and hydroxyl propyl β-cyclo…
Orthorhombic and trigonal Mo–V–oxides, which are the some of the most promising selective oxidation catalysts, were produced by the building blocks mechanism. Both oxides were produced by reaction of ammonium heptamolybdate and vanadyl sulfate under hydrothermal conditions. Structural characterization of the orthorhom…
A new semi-organic nonlinear optical crystal of Glycine Magnesium Chloride (GMC) has been grown by slow evaporation solution growth technique. The crystal system and lattice parameters were determined from the single crystal X-ray diffraction analysis. Fourier transform infrared (FTIR) studies confirm the various func…
The need of iron therapy prompted present study to develop a formulation of floating drug delivery system of carbonyl irons. Out of the chosen polymers as HPMC K15M, Sodium alginate, Carbopol 934 & HPMC K4M the positive and encouraging results in accordance to the aim have been obtained with HPMC K4M and HPMC K15M.Sod…
Quaternary MoBiGaSe5 mixed metal chalcogenide thin films have been deposited onto a conducting and non conducting glass substrates using simple and low cost arrested precipitation technique (APT). Ammonium molybdate, bismuth nitrate, gallium nitratetriethanolamine (TEA) complex agent and sodium selenosulphite are used…
The development of eco-friendly protocol for the synthesis of nanomaterials is an important aspect of nanotechnology. The green and cost-effective solution of fabrication of nanomaterials is key for biotechnology development. In this article, we report the room temperature one step bottom up synthesis of silver nanopa…
ZnO nanostructures with different morphologies e.g. nanotetrapods, nanorods, nanocombs and nanoaeroplanes has been fabricated by evaporation of pure zinc powder without catalysts in the temperature range of 400~900 °C. The structures and properties of obtained products were examined using scanning electron microscopy,…
The lightning impulse (LI) voltage test waveform for electrical power equipment is specified in IEC 60060-1 “High-voltage test techniques”. IEC TC42 made revisions to the IEC 60060-1 standard in 2010, including the introduction of a method to convert an overshoot waveform to a test voltage curve using the K-factor (te…
