A semi-implicit form of spectral deferred corrections is used in a method of lines approach to create a projection method that is sixth-order accurate in both time and space for simple domains. The derivation of spectral deferred corrections is presented and compared to traditional deferred correction methods. An auxiliary variable form of the equations for Boussinesq flow is presented which fa...
Isophotes and reflection lines are standard tools for surface interrogation. We study the correlations between them. We show that isophotes and reflection lines are different (but not disjunct) classes of surface curves. Furthermore we introduce the concept of reflection circles as a generalization of isophotes and reflection lines. Reflection circles can be considered as the mirror images of a...
evaluation of resistance to powdery mildew and some agronomic trails of barley doubled haploid lines
ninety barley doubled haploid lines originated from crossing between six barley cultivars in cereal research department, seed and plant improvement institute, karaj, iran were evaluated for resistance to powdery mildew and some agronomic traits in field in 2007. six parent cultivars and a powdery mildew susceptible check cultivar, afzal were also included. sixty two doubled haploid lines showed...
Background: In plant breeding program to produce hybrid varieties, pair of male sterile and restorer fertility lines are required. Differentiation of lines possessing restorer fertility allele from the lines lacking it remove the need for the progeny test, and thus reducing the time and the cost in the hybrid production procedure. Canola breeding program in Iran has concentrate...
in the present study, twenty two selected lines from eleven iranian eggplant (solanum melongena l.) landraces along with varamin landrace, as control, were studied in a randomized complete block design with three replications in three locations (karaj, varamin and dezful). sum of yield and marketing score for each line was recorded. analysis of variance for yield showed significant differences ...
striga hermonthica is a noxious, obligate hemi-parasite of cereal grasses that causes severe grain yield loss in susceptible maize cultivars in africa. the development of host plant resistance is one of the most practical stiga control strategies. in this study experiments on 36 maize inbred lines were conducted in pots and in field during the two rainy seasons of 2009 at kibos and alupe statio...
the theoretical and experimental investigation on the thermo-mechanical properties of carbon nanotube (cnt) as reinforcer for oil and gas pipes has increasingly become a hot research area for many engineers and material scientists in recent years. this is mainly due to the advent of the new composite material systems that exhibit exotic material and mechanical properties as compared to the trad...
In order to evaluate the effect of terminal moisture stress on 20 barley promising lines (Hordeum vulgare) and for determination of their relative tolerance, an experiment was conducted based on randomized complete blocks design with three replications in growing season of 2010-2011. In this research some old indices such as, stress susceptibility index (SSI), tolerance index (TOL), mean produc...
