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...
In Finland, the pandemic influenza virus A(H1N1)pdm09 was the dominant influenza strain during the pandemic season in 2009/2010 and presented alongside other influenza types during the 2010/2011 season. The true number of infected individuals is unknown, as surveillance missed a large portion of mild infections. We applied Bayesian evidence synthesis, combining available data from the national ...
Calcium and boron as plant nutritional elements play major roles in plant physiological processes including regulating various cell and plant functions. Considering the importance of both elements, this study was conducted during 2010-2011 in the Experimental Asian Pear Orchard at Faculty of Agriculture, Tarbiat Modares University. Different concentrations of calcium chloride (0, 0.5 and 0.7 pe...
In order to evaluate the effect of different periods of weed interference and weed control on plant height, seed yield and yield components of common bean, an experiment was conducted at the Agricultural and Natural Resources Research Center of Hamadan, Iran, in 2011. The experiment was a randomized complete blocks design with 3 replications. Treatments included two groups of weed interference ...
We combine satellite and ground observations during 1950-2011 to study the long-term links between multiple climate (air temperature and cryospheric dynamics) and vegetation (greenness and atmospheric CO(2) concentrations) indicators of the growing season of northern ecosystems (>45°N) and their connection with the carbon cycle. During the last three decades, the thermal potential growing seaso...
with population growing throughout the world, it is necessary to optimize water use,especially in agricultural lands. in order to conduct technical and economical evaluation ofdrip and furrow irrigation methods under deficit irrigation of cotton, a field experiment wascarried out during 2010 growing season at experimental farm of orzoueyeh agricultural andnatural resources research center in ke...
the experiment was carried out to study the impact of chilling and night break on the flowering of ornamental plants in their off-season period. larsenianthus careyanus (benth.) w.j. kress & mood is a wild potential ornamental ginger naturally growing in the evergreen forest of north eastern states of india was selected for the current study. the rhizomes were collected and stored at 15oc f...
the seasonal abundance patterns of the cotton aphid, aphis gossypii glover, in cotton fields at gorgan in northern iran were studied during two growing seasons of 2002 and 2003. the spatial distribution of different developmental stages and morphs of the aphid was described by fitting data to poisson (random) and negative binomial (aggregated) dis-tributions, and calculating the dispersion indi...
The distribution of the Iranian Culicinae is updated and reported by province. Larval habitat characteristics of each species, based on the information gathered throughout its range in Iran and at different times during the breeding season, are also presented.
