returning crop residues into the soil as a source of organic matter are an important source of copper and can play an important role in the soil fertility. in addition to the role of the organic matter in increasing the concentration of micronutrients in soil solution, attention should be also paid to the role of the kind and the quantity of the root’s exudates released in response to the incor...

N SEVERAL species in which cross-incompatibility is determined by I multiple oppositional alleles, different types of tests have shown that these series of alleles are very extensive. The test yielding the most decisive results and involving the fewest crosses consists of making all possible reciprocal combinations (that is, diallel crosses) between plants which have one S factor in common. Thi...

This essay in celebration of Grossman and Hart (1986) (GH) discusses how the introduction of incomplete contracts has fundamentally changed economists’perspectives on corporate finance and control. Before GH, the dominant theory in corporate finance was the tradeoff theory pitting the tax advantages of debt (relative to equity) against bankruptcy costs. After GH, this theory has been enriched b...

objective: returning crop residue to the soil exerts favorable effects on physical and chemical properties of soil. in fact, the plant residues can affect soil conditions such as ph and important role in soil fertility and cycling of elements in the soil may have. in addition to the role of the organic matter from decomposition of crop residue in increasing the concentration of micronutrients i...

Southwestern China is abundant in a large species diversity of grasses and Brachypodium sylvaticum var. breviglume is unquestionably appropriate to serve as an ideal model to investigate the adaptation, evolution and diversification of grasses in this region. In this study, a total of 37 microsatellite markers were screened and genetic variation was estimated for 100 individuals from the five n...

A total of 586 reptiles, belonging to 35 species and five subspecies, were examined in surveys aimed at determining the species spectrum and geographic distribution of ticks that infest them. Of these reptiles 509 were tortoises, 28 monitor or other lizards, and 49 snakes. Nine ixodid tick species, of which seven belonged to the genus Amblyomma, and one argasid tick, Ornithodoros compactus were...
