Diesel engines are widely used in many areas like automobiles, locomotive marine engines power generations etc., due to its high power output and thermal efficiency. Even though the diesel engines give more benefits, the human discomforts caused by the pollutant emission of these engines have to be considered. The maj…
In present study an attempt was made to prepare microparticulate drug delivery system of curcumin-Zn complex and evaluate it in albino rats spectroflurometrically. It was observed that curcumin-Zn complex was more soluble and stable than curcumin. Curcumin-Zn complex was prepared and encapsulated using sodium alginate…
Conversion of photovoltaic energy into electricity has enjoyed a prominent position within the green energy portfolio. This is because the desirious pursuit of efficient photovoltaics cells is expected to play an important role in the future energy infrastructure. This expectation has been constrained by a myriad of i…
This work is devoted to see how the magnetic field effect on the optical absorption in Light Dependent Resistance (LDR) doped with phosphors and iron . This effect is studied at different visible light wave lengths and different (xray) wave lengths. From the results, it is clear that , when one using (x-ray) , and by…
Design, Synthesis and Characterization of Transition Metal Oxide Nanomaterials as Efficient Sorbents and Emerging Catalysts and Investigation of Carbon Structure-Oxidation Activity Correlations\nLakshitha Randimal Pahalagedara, Ph. D\nUniversity of Connecticut, 2015\nKeywords: Mesoporous, Metal oxides, Desulfurization…
In this paper, a new approach to improve harmonic and reactive power compensation through the control of a shunt Active Power Filter (SAPF) using Artificial Neural Networks (ANN) in polluted environment and under unbalanced mains voltage is proposed. The ANNs learning capabilities are used to adjust the energy storage…
Bio-composites consisting of poly(lactic acid) and agricultural by-products/wastes or derived from it have been prepared by melt-blending. The effect of different filler type and contents on mechanical properties and oxygen permeability has been investigated. Moreover, these properties have been fitted with models in…
ZnSe thin films of thickness of 200 nm are deposited by vapor deposition technique and later annealed in argon at 100°C and 300°C. XRD reveals that the grain size of ZnSe phase increases with the annealing temperature. The Raman spectrum shows peaks corresponding to LO mode of ZnSe and the intensity of Raman peaks is…
Epoxy resins modified with low-viscosity hyperbranched epoxy were prepared. The tensile strength, flexural strength, impact strength, fracture toughness, glass transition temperature (Tg) of the cured samples were investigated. The results show that the addition of hyperbranched epoxy improves the overall mechanical a…
This paper results the most accurate results of Very Fast Transient over Voltages of 132 KV transformer caused by the switching operation. A 132KV transformer is designed using MATLAB simulin, the VFTOs generated by the switching operations have been analyzed and are presented. The VFTOs generated due to Disconnector…
Tri and tetra methylol urea, penta and hexa methylol melamine resins were synthesized at various combined mass of catalyst (MgCl2 and citric acid) and the rheological properties were investigated. The results show that the refractive index of 10% tri and tetra methylol urea resins gave maximum values of 1.339 and 1.33…
The nanoscience and nanotechnology nowadays are present in many areas of our life, and they will have much impact on the fields of medicine and health care. The world of medicine is very complex, so all of the benefits from nanoscience and nanotechnology to medicine will take time to become evident; however, other ben…
Vibrational properties of Gallium phosphide (GaP) diamantine,Amlodipine and(GaP) diamantine bonded with Amlodipine are investigated using density functional theory at the PBE/6-31(d) level.Physical properties of Amlodipine which is an anti-hypertensive approximately one nanometer molecule is simulated theoretically an…
Mechanical alloying method was applied to prepare nanocrystalline iron-based Fe1−xZnx solid solu- tions with x in the range 0.01 x 0.05. The structural properties of the materials were investigated with the Mossbauer spectroscopy by measuring the room temperature spectra of 57 Fe for as-obtained and annealed sampl…
In this work, we prepared biomass-based epoxy adhesives with silane-treated silicas. The effect of three types of silane-treated silicas on adhesive characterization of epoxidized soybean oil (ESO)/epoxy adhesives with different contents of ESO, i.e, 0.5, 1.0, and 2.0 wt.% was studied. As a result, the lap shear stren…
Eu 3+ doped yttrium borates were prepared by a novel low-temperature re- crystallization (RC) method. The effects of preparation techniques on the phase formation, morphologies and luminescent properties in VUV region were investigated. The use of the re-crystallization method in preparation lowered the reaction thres…
The objective of this research was to investigate the synthesis of nitrile oxides and to study their reactivity in 1,3-dipolar cycloadditions with formamidines. Chapter one looks at the literature surrounding the 1,3-dipolar cycloaddition reaction. It explores the generation of 1,3-dipoles (mainly nitrile oxides) and…
The PSTHs in panels A and B show the activity of the neuron in response to stimulation. A: response to center-out optic flow. B: response to center-in optic flow. The response to random dot patterns (A,B), to center-out optic flow (A) but not to center-in (B) and the beginning of the reward phase are readily observabl…
The research carried out on thorium-based fuels indicates that these fuels can be considered as economic alternatives with improved physical properties and proliferation resistance issues. In the current study, neutronic assessment of UO2 in comparison with two (Th- 233 U)O2, and (Th- 235 U)O2 thorium-based fuel loads…
