The aim of this study is to create TiO2 coating on the tile substrate using cell-gel and immersion method. Initially, TiO2 coating was prepared by sol gel method and then, deposition was performed in three stages with different immersion periods of 20, 40 and 60 s and finally, the samples were calcined at 450 °C. The phases and microstructural characteristics of the samples were analyzed using ...
The fatty acid composition was evaluated in field grown sesame cultivars (Sesamum indicum L.) at New Developmental Farm Agriculture University, Peshawar, KPK Pakistan during summer 2012. The experiment was laid out in RCBD with split plot arrangement having four replications each. Two sesame cultivars viz., local black and local white were sown at different dates i.e. 20 June, 10 and 30 July, a...
The purpose of this study was to identify bioactive compounds Beauveria bassiana entomopathogenic fungi derived from insect isolates Leptocorisa oratorius and endophytic B. cocoa plants that have bioactivity as growth boosters. research conducted in the laboratory Biological Control, Faculty Agriculture, Andalas University. for 4 months, using GCMS method. From results study, identified booster...
The present investigation was undertaken to develop solid lipid nanoparticles (SLN) of a hydrophilic drug Zidovudine (an anti-human immunodeficiency viral agent) and improve the entrapment efficiency of the drug in SLN. The SLN were prepared with stearic acid by process of w/o/w double-emulsion solvent-evaporation method using 3(2) factorial design. Different triglycerides alone and in differen...
Soybean oil has a wide variety of uses, and stearic acid, which is a relatively minor component of soybean oil is increasingly desired for both industrial and food applications. New soybean mutants containing high levels of the saturated fatty acid stearate in seeds were recently identified from a chemically mutagenized population. Six mutants ranged in stearate content from 6-14% stearic acid,...
Solid lipid nanoparticles (SLN) of fatty acids (FAs) were prepared with a new, solvent-free technique based on FAs precipitation from their sodium salt micelles in the presence of polymeric non-ionic surfactants: this technique was called 'coacervation'. Myristic, palmitic, stearic, arachidic and behenic acid were employed as lipid matrixes. Spherical shaped nanoparticles with mean diameters ra...
a simple, sensitive and selective method for solvent extraction and spectrophotemetric determination of lanthanum (ii) europium (iii), and cerium (iii) is described , the rare earth metals are extracted into chloroform solution of n-phenylbenzohydroxamic acid (pbha) at ph 9-10 various parameters are studied to optimize the extraction conditions. the molar absorptivity is found to increase from ...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
Suggestions have been made that saturated fatty acids with 12-18 carbon atoms, stearic acid (18:0) in particular, are prothrombogenic. These suggestions are based mainly on in vitro measurements. In the present study the effect of dietary fats high in stearic or myristic acid (14:0) on plasma triacylglycerol concentrations and key variables of blood aggregation (in vitro and in vivo), coagulati...
In the study, it was aimed to determine constituents of laurel fixed oil obtained from different genotypes (Laurus nobilis L.), which is one natural plants region and widely found in flora Hatay, by traditional, cold press soxhlet extraction methods. When GC/MS analysis results these oils were examined, main components traditional method as capric acid (2.49%), lauric (1.17%), myristic (0.16%),...
