objective:the purpose of this study was to investigate the effects of piroxicam co-administration with ethanolic stem-bark extract of khaya senegalensis on biomarkers of oxidative stress and gastro-toxicity in wistar rats. materials and methods: thirty healthy male and female albino wistar rats (190-220 g) were grouped into six (n = 5) with designated treatments including: normal saline, piroxi...

abstract- the effects of iron (fe) and zinc (zn) treatments on the growth and nutrient composition of chickpea were studied in a greenhouse experiment arranged in a completely randomized design. while the application of fe decreased mean shoot dry weight of chickpea, that of zn had no significant effect on chickpea shoot dry weight. increasing fe levels drastically decreased mn concentration an...

the ammi and sreg gge   are among the models that effectively capture the additive and multiplicative components of genotype × environment interaction (gei) and provide meaningful interpretation of multi-environment trials’ data set in the breeding programs. the objective of this study was to assess the effect of gei on grain yield of barely advanced lines and exploit the positive gei effect us...

experimental results of dielectric investigations for binary mixtures of 2, 3-butanediol, 2, 3-bd, in2-ethyl-1-hexanol, 2eh, were reported for various mole fractions and temperatures (298.2-308.2) kand they were used to calculate dielectric parameters such as kirkwood correlation factor, excesspermittivity and bruggeman parameter. these parameters were used to carry out temperaturedependent die...

wind turbines are important devices that extract clean energy from wind flow. the efficiency of wind turbines should be examined under various working conditions in order to estimate off-design performance. numerous aerodynamic and structural research works have been carried out to compute aeroelastic effects on wind turbines. most of them suffer from either the simplicity of the modelling appr...

ground differential movements due to faulting have been observed to cause damage to engineered structures and facilities. although surface fault rupture is not a new problem, there are only a few building codes in the world containing some type of provisions for reducing the risks. fault setbacks or avoidance of construction in the proximity to seismically active faults, are usually supposed as...
