Meloxicam is a non steroidal anti-inflammatory drug, used in the treatment of rheumatoid arthritis and oestoarthritis. It is practically insoluble in water leading to poor dissolution, variations in bioavailability and gastric irritation on oral administration. In order to modulate its gastric side effect and to increase aqueous solubility, physical mixture and solid dispersion of the drug were...
among different spd techniques, equal channel angular pressing has attracted the most attentions,because of applying large strain to solid bulk materials. in this research, ecap process up to 6passes was carried out on a pure copper and a 6012 al-mg-si alloy with bc route in ecap dieswith φ=120 and ψ=20 and diameter of 20and 10 millimeter respectively. moreover, x-raydiffraction (xrd) system wa...
in recent years, there has been a growing interest among researchers to investigate the relationship betweenteacher self-efficacy and classroom behavior management, especially students misbehavior. therefore, this study aimed to comparatively investigate english and arabic teachers’ use of different behavior managementstrategies, their self-efficacy, and their success in an iranian context. th...
to be the biggest problem associated with stand establishment. Previous work has indicated that drought Planting rhizoma peanut (Arachis glabrata Benth.) directly into stress, particularly in the 3 mo postplanting is one of grass sod may be practical for producers [e.g., cow-calf (Bos taurus) the main reasons stands fail to establish or establish production, low maintenance roadside or turf sit...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
Al2O3/TiC composites are used as cutting tools for machining gray cast iron and steels. The addition of iron improves the toughness of Al2O3/TiC composites. Ilmenite, aluminum and graphite can be used to produce in-situ Al2O3/TiC–Fe composites. However, the formation mechanism and reaction sequences of this system are not clear enough. Therefore, the present research is designed to determ...
Babol local lettuce as a landrace in Mazandaran, has cultivated for many years. Local lettuce is a mixture of different genotypic and phenotypic forms which affects its marketability. It was purified by individual selection method during a three year priod (1998-2000) based on the selection for characteristics such as shape of bush, closed pome high yield, good marketability and resistance to d...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
Experimental evidence, the heuristics of indistinguishability, and its logical inconsistency with quantum formalism all argue against the existence of a quantum mixture uncorrelated with the exterior, hence argue for the postulate “The state of a system uncorrelated with its exterior is pure.” It is shown that this is equivalent with “The state of a system describable in terms of indistinguisha...
Experiments were conducted during the summer of 2002 at the Rice Research and Extension Center, Stuttgart, AR, to evaluate: 1) various timings of sequential applications of imazethapyr at 0.063 lb/acre (4 oz Newpath/acre) in conventional and staleseedbed rice planting systems utilizing Clearfield ‘CL-161’ and 2) the timing of clomazone application at various rates and timings in conventional ri...
