Cefixime is widely used as prescription and no-prescription medicine. The aim of study, is aimed at developing and optimizing liposomal formulation of cefixime in order to improve its anti-cancer activity, to prepare cefixime liposome using thin lipid film hydration using rota evaporator (Mechanical dispersion) which…
In this paper we present a relation for continuous slowing down approximation (CSDA) ranges for electrons and positrons of Carbon, Aluminium and Copper in terms of energy from 700 keV to 50000 keV and have been fitted by a second order polynomial approximation with two parameters. These parameters depend upon the atom…
Labisia pumila (Myrsinaceae) or commonly known as ‘Kacip Fatimah’ is traditionally used by Malaysian women to address reproductive health. In this study, we investigated the effects of standardized water extract and methanolic extract of Labisia pumila on the collagen synthesis in UVB-irradiated and non-irradiated Hum…
The carding process has a major influence on the sliver quality and the resulting yarn characteristics because it is the first sliver forming process step. The effect of opening, carding, drawing and combing on single fiber and bundle cotton properties were studied by employing AFIS and HVI testers. The basic purpose…
Sealing performance in general in centrifugal compressors and, in particular, in sour gas applications is extremely important to prevent safety issues and EHS concerns. As known, H S starts to become lethal at concentrations in excess of 100 ppm. In general, elastomeric O-ring gaskets (such as FKM-Fluor elastomer or F…
An optimal design method for and hybrid active power filters (HAPFs) set at high voltage levels to satisfy the requirements of Harmonic filtering and reactive power compensation. Multi objective Optimization models for HAPF were constructed. Detuning effects and faults were also considered by constructing Constraints…
This paper deals with the electron optical properties of a set of asymmetrical electrostatic immersion lenses with two electrodes which have been designed using different angles (θ) of the outer lens electrodes as well as air gaps (S) between the electrodes of each lens. It was found that the angle of the outer electr…
In this review the utility of the inorganic ring systems, c yclophosphazenes and cyclocarbophosphazenes, to support multisite coordination platforms is described. Different types of ligands based on these ring systems and their metalation behavior is described.
Nowadays, the continuous rise of the population in the world emerges diversification of the energetic sources, for reliable energy supply. Furthermore, the sustainable development of the modern communities relies to environmentally friendly energy production equipment. In this aspect the present work has attention to…
HgxCd1-xS is a technically important class of material owing to its widespread utility in a variety of optoelectronic devices. The structural characteristics and microscopic features of this important composite material obtained using a liquid phase chemical deposition process have been investigated. A series of HgxCd…
INTRODUCTION The main goal of drug delivery and targeting by microbubble is to improve the efficiency of drug action in the region, where the disease cells are arisen and reducing undesired adverse effects, such as toxicity, in the healthy tissues. For the drug action and/or deposition in the targeted region various e…
). The heat treatment of the nanoparticles at two temperatures (900 °C and 1100 °C) formed porous agglomerated iron-doped alumina nanoparticles. The heat-treated powders were characterized by X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscopy. Characterization results
For power transformers, the magnitude of the first peak of inrush current is ten times more than the rated load current. The main feature of this current is its high amplitude and second harmonic content. An uncontrolled inrush current may lead to the inadvertent operation of the circuit over-current protection system…

Nickel doped cobalt ferrite magnetic nanoparticles were synthesized in a homogeneous aqueous solution in presence of surfactant by co-precipitation route. the particle size was estimated by the full width half maximum (FWHM) of the strongest X-ray diffraction (XRD) peak. The average particle size varied in the range o…
In recent years, there is a growing interest for the use of natural materials in composite applications, where cellulose materials are reinforced in foam gypsum matrix. A result is environmentally friendly low density building material, which can show high tensile and compressive strength, good heat and sound insulati…
The International Atomic Energy Agency (IAEA) promotes safe and effective management of radioactive waste and has suitable programmes in place to serve the needs of Member States in this area. These programmes cover the development and use of safety standards, planning, technologies and approaches needed for the manag…
The mixed ligand complexes of Co (II), Ni (II), Cu (II) and Zn (II) with Schiff bases N-(2-hydroxy-1- naphthylidene)-4-chloroaniline (L1H) and N-(2-hydroxybenzylidene)-2,3-dimethylaniline (L2H) have been synthesized and characterized. The resulting complexes were characterized by elemental analysis, thermogravimetric…
In the present work Zinc Aluminum Oxide (ZAO) thin films have been deposited on glass substrates by DC reactive magnetron sputtering technique at different sputtering powers of Zn varied from 85 W - 125 W. XRD patterns exhibits ZAO thin films had a diffraction peak corresponding to (0 0 2) preferred orientation with c…
Tungsten based microemitter tips have been prepared with various tip radii ranging from 30 to 100 nm. These tips were manufactured by electrochemical etching of a 0.1 mm diameter high purity (99.95%) tungsten wire at the meniscus of two molar NaOH solutions. Contrary to the standard procedure, the tips' surfaces have…
