We report on a comprehensive set of observations of Gamma Ray Burst 050716, detected by the Swift satellite and subsequently followed-up rapidly in X-ray, optical and near infra-red wavebands. The prompt emission is typical of long-duration bursts, with two peaks in a time interval of T90 = 68 seconds (15 – 350 keV). The prompt emission continues at lower flux levels in the X-ray band, where se...
abstract this study was conducted to evaluate the resistance of 70 genotypes of barley to powdery mildew. after preparing the samples contaminated with powdery mildew, reproduction of the spores of the fungus was conducted on susceptible cultivar afzal. the experiment was conducted with randomized block design in pot in greenhouse. seedlings were inoculated with the spores fungus in two-leaf st...
Aging mechanisms of two polymeric insulation materials that are used widely in nuclear power plant low-voltage cables; cross-linked polyethylene (XLPE) and ethylene propylene rubber/ethylene propylene diene terpolymer (EPR/EPDM), are reviewed. A summary of various nondestructive methods suitable for evaluation of cable insulation is given. A capacitive sensor capable of making local nondestruct...
The present study aims to describe and bring out the tectonic nature of Ijai watershed in parts Kangpokpi, Tamenglong Noney districts Manipur. has an area 184.0 Km2which is also tectonically active as depicted by analysed values different geomorphic indices like SLK index, Valley Floor Width Height ratio (Vf),Transverse Topographic Symmetry (T), Drainage Basin Asymmetry (AF), Elongation Ratio (...
In this paper, the specimens of polymer-cement composites after 1 d, 7 15 and 30 d aging without UV are subjected to fixed extension test tensile test. By observing mode composite in fixed-elongation test, measuring elastic recovery rate, strength, elongation at break, peak strain, toughness pre-peak composite, effects on bonding properties were studied. And combining with scanning electron mic...
The aim of this study was to produce Carboxy Methyl Cellulose (CMC) and Poly Vinyl Alcohol (PVA) films and to enhance their properties by reinforcing them with nanoclay particles. Thus, nanocomposite films were prepared with blending of CMC and PVA, as a matrix and several filler loadings of nanoclay particles. The various formulations of nanocomposite films obtained with casting m...
In order to increasing of hydroxy functionality of HTPB an in-situ nitroxide mediated polymerization (NMP) of 1,3-butadiene was carried out in presence of TEPA as a polyfunctional nitroxide precursor. The multi-modal molar mass distribution of the product was elucidated by reductive hydrolyzation of the oligomeric product. The new polyfunctional hydroxyl-terminated polybutadiene (PFHTPB) was c...
introduction recently, considering the fact that access to high quality feed stuffs is limited, using agricultural by-products in animal nutrition has taken to consideration. effective use of these products as alternative energy source for ruminant feeding is important for economical and environmental reasons. major limitation for using agricultural by-products as ruminant feed stuffs is their ...
Background & Objective: Fennel, as an edible plant, and due to its estrogenic compounds, has widely been used as a therapeutic agent for centuries. In this study, the effects of neonatal exposure to fennel alcoholic extract (FAE), on the onset of puberty, estrus cycle, ovaries, and lordosis were investigated. Materials & Methods: In this experimental study, 48 female BALB/c pups were divid...
