in order to study the correlation between morphophenological and quantitative traits with yield and to determine the most important traits for yield, 600 ecotypes of mung bean were evaluated in normal and limited irrigation conditions through augmented design. computation of correlation coefficients showed that in two conditions, number of pods per plant, harvest index and biological yield had ...

Since the work of André Martinet back in the 60’s [7], the notion of ‘economy’ has been accepted as one of the main principles underlying the organization of phonological inventories (hereafter PI). This principle, also named MUAF (‘Maximal Use of Available Features’) by John Ohala [8], states that PI are organized along a few phonetic dimensions that they tend to maximize in terms of number of...

An efficient, step-economical, and scalable approach to the synthesis of polypropionate stereotriads has been developed. Either 2-butyne or propyne is subjected to rhodium-catalyzed silylformylation and in situ crotylation of the resulting aldehydes. Tamao oxidation under either "standard" conditions or "aprotic" conditions then delivers the completed stereotriads in a three-step, two-pot seque...

A friendly benign, green, rapid and facile strategy for synthesis a series of arylquinoxalines was achieved by condensation of aromatic 1,2-diamines with arylglyoxals under clay-catalyzed as an inexpensive and eco-friendly catalyst using grindstone chemistry. Significant decreases in reaction times and high yields have been observed by this green chemistry approach in comparison with previously...
