Water scarcity and salinity are important limitations for saffron (Crocus sativus L.) production in arid and semi-arid regions. The purpose of this research was to study the interaction effects of water salinity and deficit irrigation on the macroscopic water extraction model for saffron. The effect of salinity and water stress on root-water uptake coefficient was determined by additive and mul...

In this paper, we have modified the stress integration scheme proposed by Choi and Yoon [1]; which is based on numerical approximation of yield function gradients, to implement in finite element code ABAQUS three elastic isotropic, plastic anisotropic constitutive models with yielding described Yld2004-18p [2], CPB06ex2 [3] Yld2011-27p [4] criteria, respectively. We developed both VUMAT UMAT su...

Rice (Oryza sativa) is the primary food source for more than one-half of the world's population. Because rice cultivation is dependent on water availability, drought during flowering severely affects grain yield. Here, we show that the function of a drought-inducible receptor-like cytoplasmic kinase, named GROWTH UNDER DROUGHT KINASE (GUDK), is required for grain yield under drought and well-wa...

Fluorescence properties (quantum yield, decay curve, lifetime and polarization) of acridine orange and proflavine bound to DNA were examined as a function of nucleotide to dye (P/D) ratio. First, mean fluorescence lifetimes were determined by the phase-shift measurements. The lifetime and quantum yield of acridine orange increased in a parallel fashion with increasing P/D ratio. There was no pa...

chickpea (cicer arietinum) is the third most important pulse crop in the world, grown widely across asia and the middle east. weed is one of the main limiting factors in chickpea (cicer arietinum) production. several characteristics of chickpea (cicer arietinum), such as slow plant emergence, short plant height, and chickpea morphology allow weeds to compete effectively. to investigate the effe...

In this paper we develop combinatorial methods for the evaluation of yield and operational reliability of fault-tolerant systems-on-chip. The method for yield computation assumes that defects are produced according to a model in which defects are lethal and affect given components of the system following a distribution common to all defects; the method for the computation of operational reliabi...
