higher values (106-82%) than the control (73 0 ). The linear densities of the alternative agents were higher than the control. The alkalinity and acidity (pH) of the alternative agents after the scouring process were environmentally friendly in comparison with the highly alkaline NaOH (control), thus unfriendly. The c…
A gel polymer electrolyte (GPE) based on an electrospun membrane of Poly (ethylene oxide) / Polyurethane (PEO/PU) incorporated with lithium ions was prepared and its performance in lithium batteries were studied. Blended form of PEO and PU electrospun fibrous membranes were prepared by electrospinning technique. Incor…
Different techniques of micro-image analysis of nonwoven structures have been discussed in this article. The characteristic features of these techniques have been critically examined. The instruments used of these techniques have been described with schematic d iagrams. The advantages and disadvantages to the techniqu…
Dispersion remains, today, a highly topical subject. Our group has been interested in characterizing this phenomenon by pulsed-field-gradient NMR technique. Direct measurement of the dispersion coefficient can be done with a Pulsed Gradient Spin Echo (PGSE) sequence by assuming that the asymptotic regime is reached. I…
Ecofriendly cement may be obtained by partial replacement of cement with certain low cost waste materials. Sugarcane bagasse ash is one such material which is a residue resulting from the burning of sugarcane bagasse in boilers for power generation. Sugarcane bagasse ash (BGA) is a waste material and being disposed to…
The fields of landfilling of conventional waste and that of surface disposal of nuclear waste have developed quite independently and also partly out of phase with each other. The paper analyses what knowledge and experience might be mutually beneficial as well as what further knowledge may be needed.It is found that e…
The inhibitive effect of the extract of Salvia Judica on aluminum corrosion in 1 M NaOH solutions was investigated by using the weight loss method at different temperatures. It was found that the extract play as corrosion inhibitor for aluminum corrosion in 1 M NaOH solution. The inhibition action of the extract was d…
Abstract: Thermodynamics of Cobalt (Co) exchange using a kinetics approach was investigated in alluvial soil samples from two surface soil samples (0-30 cm) of Egyptian soils selected from Nile Delta mainly varied in clay content and other related properties. Kinetics of adsorption and desorption were determined at te…
bstract A In this work, a series of novel 1-(2-(4-xphenyl)-5-(phenylamino)-1,3,4oxadiazole-3(2H)yl) ethanone (X=H,OH,Cl,NO2,N(CH3) (4a-e) were prepared from the condensation of Schiff base (3a-e) with acetic acid. The azomethines were prepared from the corresponding 4phenyl semi carbazide(1) with aryl aldehydes (2a-e)…
This work was to evaluate the efficacies of the nanoparticles (NPs) of silver (Ag) and Gold (Au) against the major tropical mosquitoes. In the present study, the Ag and Au NPs were synthesized by using the cell free extract of Fusarium oxysporum f.sp. pisi fungus. The bioreduction of AgNPs and AuNPs was monitored by u…
Freshly harvested tomato fruit (Solanum lycopersicum) were pre-treated with 0, 50, and 100 µM prohexadione-calcium (Pro-Ca) and then stored at 1 °C for 21 days to investigate the effect of Pro-Ca treatment on electrolyte leakage (EL), malondialdehyde (MDA), proline and total phenols contents, and activity of phenylala…

The paper outlines how experiments were carried out to determine the optimum chromium/carbon (Cr/C) ratio that brings the required hardness of 65HRC an d to establish a quenching technique for the grindi ng balls. Matlab was also used to develop a mathematical model for the ball wear rate and its cost effectiveness ba…
Fabric properties such as pilling and abrasion resistance and tensile strength vary when greige fabric is processed further. The quality of dyed fabric depends on the quality of greige fabric. Cotton Plain and Twill weave fabrics were woven at three different warp yarn tension and then dyed using monochlorotriazine, D…
Necuron is a polyurethane material (PUR) that is used for various applications of industry. The use of these materials in industry increased in recent years because of their good mechanical and machinability properties. Good knowledge of the mechanical behaviour of these materials is highly important therefore this wo…
Present paper studies the possibility to obtain polymer-clay nanocomposites using poly(3methacrylamidopropyl (N,N-dimethyl) dodecyl ammonium bromide) and several commercial clays- Cloisite Na, Cloisite 30B, Cloisite 93A, Cloisite 20A, Cloisite 15A in three different solvents (ethanol, chloroform and propyleneglycol mo…
pressure. The deposited thin films were annealed at 150 ° C in tube furnace in the presence of argon gas. For characterization, thin films were subjected to X-ray diffraction (XRD), SEM, EDS and J.A. Woollam variable angle ellipsometry (VASE) for structural, surface morphological, elemental composition and optical pro…
Abstract-- The effect of carboxylic acid from Palm kernel oil (PKO) on carbon steel SAE 1045 in 1M hydrochloric acid (HCL) media by using weight loss technique for corrosion prevention. The inhibition efficiency of PKO was calculated using weight loss technique. Weight loss and corrosion rates of carbon steel decrease…
Candesartan is an angiotensin-receptor blocker (ARB) with very low bioavailability approximately 15% that can be improved by increasing its solubility and dissolution rate. The aim of this study is to enhance dissolution of candesartan as a model hydrophobic drug through application of liquisolid technology. It was fo…
Summary: Ag NPs were synthesized by the chemical reduction method and were optically characterized. The change in size of the nanoparticles and position of surface Plasmon resonance was studied as a function of concentration of different reactants by using UV-Visible spectroscopy. Red shift was observed in the positio…
