The effect of soaking time and temperature response for coconut and raffia fibre reinforced composite on their mechanical properties have been studied. Tensile and compression test for treated and untreated were performed using a universal testing machine (Monsanto Tensometer). The conditioned samples in each case sho…
Introduction: In Nuclear Reactor the leakage in form of radiations becomes highly beings. The radiations from the nuclear reactor are always under serious consideration due to fatal and miserable results to human race. Every precautions and extra care is taken to avoid any miss carelessness or due to failure of some e…
A specific stability indicating high-performance th in-layer chromatographic method for analysis of zal toprofen both as a bulk drug and in formulation was developed and validated. The method employed HPTLC aluminium pla tes precoated with silica gel 60 F 254 as the stationary phase. The solvent system consis ted of M…
The purpose of this study was to synthesize, characterize and investigate the corrosion inhibitory effects of a Schiff base that can inhibit mild steel more efficiently at higher temperature. Weight loss and gasometric methods were used to study the corrosion inhibition of mild steel in sulphuric acidic solution by 4-…
Graphene, a two-dimensional atomically thin honeycomb lattice, has emerged as the subject of tremendous interest because of its unique structure and outstanding physical, thermal, mechanical, and electron transport properties. Graphene has a lot of potential applications, such as in catalysts, photovoltaics, field eff…
Welds of thick plates (304 SS) clad with Ti of commercial purity in as-received state and also after subsequent heat treatment and/or after hydrogen charging were investigated. Fatigue tests were carried out at amplitude of 20 Hz and in case of bimetal without hydrogen charging also at amplitude of 40 Hz. After heat t…
In the present work we reported the phytochemical analysis of n-buthanol extract of Limoniastrum feei (Girard) Batt. a plant belonging to Plumbaginaceae family. A new phenolic compound (1) together with six know compounds were isolated. Their structures were elucidated by 1D and 2D NMR experiments including 1D TOCSY,…
SYNTHESIS AND PROPERTY INVESTIGATION OF METAL-BASED NANOMATERIALS FOR BIOTECHNOLOGICAL APPLICATIONS Nalin Dammika Darsanasiri Western Carolina University (April 2014) Director: Dr Channa R. De Silva Luminescent lanthanide-based materials have drawn recent interest due to their applications in in vitro cellular imaging…

Themolecular mechanisms involved inthis process arenotyetunderstood butarecurr…
The phenomenon of water vapour sorption by anhydrous C3A polymorphs both in the absence and in the presence of CaSO4 . 0. 5H 2O was studied utilising dynamic and static sorption methods. It was found that orthorhombic C3A starts to sorb water at 55% relative humidity (RH) and cubic C3A at 80% RH. Also, C3Ao sorbs a hi…
Summary: A series of poly(L-lactic acid)/poly(tetramethylene glycol) (PLLA/PTMG) blend films were prepared by casting the polymer blend solution in chloroform. Surface morphologies of the PLLA/PTMG blend films were investigated by scanning electron microscopy (SEM). Thermal, mechanical, and chemical properties of PLLA…
Among various controlled-release drug delivery systems, in situ forming hydrogels are more attractive than others due to their biodegradability and easy preparation.In this study, water soluble and biodegradable triblock copolymer PCL– PEG–PCL was synthesized and used to form supramolecular hydrogel by complexation wi…
Soft gelatin capsules are also known as soluble elastic or soft elastic capsule.The composition of soft gelatin capsule differs from hard gelatin capsule in that sugar the sugar is replaced by a plasticizer like glycerin ,sorbitol or a similar polyol.plasticizer impart elastic properties to capsules.The soft gelatin c…
Owing to the convenience of fresh cut fruits and vegetable, the demand for ready to eat fresh cut fruits and vegetable has grown exponential increase in the market. However fresh cut produce cannot be kept for longer period due to serve stress exerted on the cut surface resulting in faster deterioration. In order to m…

In this work it was possible to synthesize and characterize the ligand of N-salicylidene-β-alanine (KHL). A series of metal caffeine complexes involving a tridentate (NO2)-donor Schiff base and two monodentate N9 caffeine and water coordination with the composition [M(LH)(Caff)2H2O]n; M = Cd2+, Zn2+, Ni2+, Cu2+; Caf =…
This paper deals with the analysis of Aluminium profile manufacturing industries by extrusion process .The Analysis of Aluminium profile manufacturing industries will be done by selecting various alternatives and attributes .The Aluminium profile manufacturing industries are selected and they are ranked according to t…
A B S T R A C T In this paper, Moving Average Filter as new approach for harmonic reduction in non- ideal source conditions is presented. Moving Average Filter is used to compensate reactive power and harmonics caused by non-linear loads, so that the current which is drawn from the source has no harmonic and the power…
The service lives of dies in forging processes limited by wear, fatigue fracture and plastic deformation, etc. in hot forging processes, wear is the predominant factor in the operating lives of dies. In this study, the wear analysis of a closed die hot forging process has been realized. This study aims to reduce die w…
The matrix of decellularized organ retains the three-dimensional architecture and biochemical composition, as well as the original tissue microvasculature. This propertie make the decellularized lung very promising for the generation of functional bioartificial organs. This study aims to describe an experimental anima…
