to evaluate the response of wheat to drought stress and salicylic acid, this field experiment was carried out at the experimental farm of college of agriculture, university of shahid bahonar kerman, iran in 2011-2012, in a split-plot arrangement using completely randomized block design with four replications. main plot was irrigation (normal irrigation and cut off at flowering) and sub plot was...

The accurate estimation of age using methylation data has proved a useful and heritable biomarker, with acceleration in epigenetic age predicting a number of age-related phenotypes. Measures of white matter integrity in the brain are also heritable and highly sensitive to both normal and pathological aging processes across adulthood. We consider the phenotypic and genetic interrelationships bet...

a special class of cubic graphs are the cycle permutation graphs. a cycle permutation graph pn(α) is defined by taking two vertex-disjoint cycles on n vertices and adding a matching between the vertices of the two cycles.in this paper we determine a good upper bound for tenacity of cycle permutation graphs.

Brown spot disease caused by Alternaria alternata (Fr.: Fr.) Keissl is a serious problem forproduction of tangerines and tangerine hybrids in Iran. The Tangerine pathotype causes brownspot disease on young leaves and immature fruits of limited varieties of mandarins and tangerines(Citrus. reticulata Blanco). Specificity in the interaction between tangerine and the pathogen isdetermined by a hos...

Based upon ecological data provided by a 6-year study of native species assemblage structure and function in near-pristine Limahuli Stream (Kauai), The Hawaii Stream Index of Biological Integrity (HS-IBI) incorporates 11 metrics covering five ecological categories (taxonomic richness, sensitive species, reproductive capacity, trophic-habitat capacity, and tolerance capacity). The HS-IBI was sho...

background: it is established that sperm dna integrity is essential in fertilization and normal embryo and fetal development. routine semen analysis gives an approximate evaluation of the functional competence of spermatozoa, but does not always reflect the quality of sperm dna. therefore, the evaluation of sperm dna integrity, in addition to routine sperm parameters, could add further informat...

Many languages use definite and indefinite articles to signal the referential status of individuals in conversational space. But articles are not necessary to set up or maintain discourse reference, as witnessed by the fact that languages can also get by with bare nominals. Similarly, we find that many, but not all languages use a morphological singular/plural contrast to distinguish reference ...

This work concerns the problem of modelling evolving prospective agent systems. Inasmuch a prospective agent [1] looks ahead a number of steps into the future, it is confronted with the problem of having several different possible courses of evolution, and therefore needs to be able to prefer amongst them to decide the best to follow as seen from its present state. First it needs a priori prefe...

Water management is a crucial tool for addressing the increasing uncertainties caused by climate change, biodiversity loss and conditions of socioeconomic limits. The multiple factors affecting water resources need to be successfully managed achieve optimal governance thus move towards security. This study seeks obtain holistic vision various threats that affect ecological integrity basins form...
