Single crystals of L-Histidinium Trifluoroacetate were grown from aqueous solution by slow evaporation technique. Single crystal X-ray diffraction analysis reveals that the crystal belongs to triclinic crystal system. The optical transmission studies show that the crystal is transparent in the entire visible region wi…
Results on synthesis, structural investigations and the morphology of complex perovskites of general formula PrCo 1–x Cr x O 3 (with x = 0, 0.33, 0.5, 0.67 and 1) are presented. The synthesis of the perovskites within this series was performed by solution combustion method using two different fuels: urea and glycine.…
Seagrasses meadows are highly productive ecologically and economically valuable ecosystems. Epiphytic diatoms were collected from the leaves of seagrass species in Enhalus acoroides in Thondi coastal region. The taxonomic composition was identical regardless of the seagrass species. This is the first record of this ep…
Polycrystalline zinc sulfide (ZnS) films were prepared on glass substrates using a chemical bath deposition (CBD) technique in an aqueous/ethanolic solution. The films were characterized by X-ray diffraction (XRD) and electrical conductivity measurement. The XRD studies revealed that the deposited films have a polycry…
Most anticancer drugs are greatly limited by the se rious side effects that they cause. Tamoxifen is to xic to cancer cells and used against breast cancer. However, it m ay lead to irreversible cardio toxicity, which coul d even result in congestive heart failure. It decreases white blood cells count with increased ri…
We studied the microcrystalline and nanocrystalline silicon thin films by means of Raman spectroscopy technique. The applied external electric field causes the changes in the electric dipoles' orientations to compensate the external field, and migration the atom of impurities, such as hydrogen, and point defects. The…
Within Electric Power Utility of Serbia 1991, a thermal power plant 'Kostolac B', power 2 × 350 MW, started. Based on the examination of steam boiler pipe system, it is confirmed that it is in a 'bad' shape. Its most jeopardized parts are evaporating heating surfaces. Considering that there are areas within the evapor…
Catalyst pellets are one of the most important factors in catalytic reactor design. In this research a single catalyst pellet of hydrodesulfurization reaction have been investigated. The governing mass and energy balance equations have been solved numerically under steady state and dynamic conditions aiming to find th…
The technique of liquisolid compacts is a promising method towards enhancing the dissolution of poorly soluble drugs. In the present study, the potential of liquisolid systems to improve the dissolution properties of water-insoluble agents was investigated using diclofenac sodium as the model drug. Several formulation…
The critical relationship between quantitative stru cture-property relationships (QSPRs) and the qualit y of the experimental data is discussed by using multiple li near regression (MLR) analysis and describe the act ivities and influences of the vibrational frequency ( stretchin g & bending ) for groups C=C and =CH 2…
Cobalt substituted Nickel-zinc ferrites of different compositions Ni0.95-xZn0.05CoxFe2O4 and Zn0.95xNi0.05CoxFe2O4 (where x = 0.00, 0.01, 0.02,0.03, 0.04, 0.05 and 0.06).have been prepared by citrate precursor method involving concerned metals and mixing them in solution state. Parts of the sol-gel powder heated at el…
A new RP-HPLC method was developed for selective and simultaneous determination of of Desogestrel and Ethinyl Estradiol Tablets. The chromatographic separation was achieved on a Zorbax SB C-18, 4.6 x 250mm, and 5µ column. The gradient LC method employs solutions A and B as mobile phase. The solution A milliQ water and…
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.
