The concept of stability is important for the selection crop Cultivars and in breeding programs. aim this work was to evaluate productivity some bread wheat cultivars under rainfed conditions different locations NWCZ Egypt. Results current study showed that studied performed differently environment and. AMMI analysis revealed responsible most yields variation also AMMI2 bi-plot East Barrani fir...

fusarium head blight (fhb) is an important disease in wheat worldwide that reduces grain yield, quality as well as contaminates grains to the mycotoxins. thirty spring wheat genotypes including 28 bread wheat and two durum wheat genotypes were evaluated for fhb under a randomized complete block design with three replications. grain yield and its components were evaluated by using two environmen...

a two years (2006–2007 and 2007-2008) experiment was conducted at national salinity research center, yazd, to evaluate salt-tolerant genotypes of brassica napus, b. rapa and b. juncea. to screen genotypes in the first growing season, 58 genotypes were grown under two irrigation water salinity levels of 2 and 12 ds m-1 in an augmented randomized complete block design with six replicated checks. ...

There are several examples of heuristic rules first proposed from empirical observation, which eventually earned physicochemical validity after the fundamental derivation of a posteriori. This may be the case of Sherwood’s plot – for which a sound rationalization from first principles, entailing enthalpy and mass balances, is provided here; it applies to (fine) chemicals undergoing concentr...

Mammographic risk assessment provides an indication of the likelihood of women developing breast cancer. Anumber ofmammographic image based classification methods have been developed, such as Wolfe, Boyd, BI-RADS and Tabár based assessment. We provide a comparative study of these four approaches. Results on the full MIAS database are presented, which indicate strong correlation (Spearman’s > 0....

Many relations between model elements are expressed in OCL. However, tool support to enable synchronization of elements based on OCL-expressed relations is lacking. In this paper, we propose to use active operations in order to achieve incremental execution of some OCL expressions. Moreover, bidirectionality can also be achieved in non-trivial

This paper demonstrates the existence of bi-directional relationships between interfirm collaboration and business sales. Entry and post-entry collaboration often contribute to superior performance, which in turn attracts more partners. At the same time, though, collaboration may impose constraints on growth opportunities. The relationships vary across types of collaborators and collaborations ...
