low seed yield is a limiting factor for cross breeding and hybrid seed production in cyclamen. this study was performed to investigate pollen germination and its relation to cross-pollination success and fruit set in this plant. in order to achieve a high level of pollen germination, the effect of different concentrations of chemical compounds were examined on in vitro pollen germination of cyc...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
BACKGROUND Plants can rapidly evolve resistance to herbicide in response to repeated selection. This study focuses on cross-resistance patterns observed in Lolium rigidum following pyroxasulfone recurrent selection. RESULTS The parental MR (multiresistant) population following four generations of pyroxasulfone recurrent selection evolved cross-resistance to prosulfocarb and triallate. At the ...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
the identification of molecular markers linked to leaf curl virus (clcuv) disease resistance in cotton has the potential to improve both the efficiency and the efficacy of selection in cotton breeding programs. genetic analysis suggested that clcuv resistance is controlled by a single dominant gene. in this study, an interspecific f2 population derived from a cross of gossypium barbadense and g...
in this study reference as one of the five cohesive devices in the achievement of textuality in english and persian narrative/descripitive written texts is focused on and analysed . to do so , the theoretical framework elaborated by halliday and hasan (1976) and its version adapted by the writer to match the sub-types of reference in farsi are applied to the analysis of reference in english and...
Medium effects in K + nucleus interaction from consistent analysis of integral and differential cross sections Abstract Self consistency in the analysis of transmission measurements for K + on several nuclei in the momentum range of 500-700 MeV/c is achieved with a 't ef f (ρ)ρ' potential and new results are derived for total cross sections. The imaginary part of the t ef f amplitude is found t...
Background and Objective: Reduction of the anabolic to catabolic hormones plays an important role in muscle loss and strength reduction in post-menopausal women. The ratio of testosterone to cortisol concentration (T:C) is used as indicative of the stress level imposed by the exercise. Increases in this ratio are responsible for hypertrophy and strength gain. The objective of the pres...
to evaluate the effect of nitrogen fertilizer amounts on grain yield of forage corn in 2012, a pilot was implemented in islamic azad university agricultural research station, isfahan, as a split plot in a randomized complete block design. main plots consisted of four levels: control (no fertilization ) , 50 , 100 and 150 kg per ha nitrogen from urea source and subplots , including several varie...
Results 712 (male 77.5%) patients were operated on, with 609 (85.54%) being isolated CABG and 103 (14.46%) combined CABG with AVR. Average age in isolated CABG and combined groups were 66 and 73 years respectively. Average additive EuroScores were 3.5 and 7.29. 21.6% cases were performed by trainee or staff grade surgeon. In hospital mortality was 0.16% in isolated CABG and 0% in CABG with AVR ...
