Dear Editor, I read the original article by Keshvari et al. published in the previous issue of the Iranian Red Crescent Medical Journal with interest. 1 At first, the large number of samples (367 samples) was impressive. Although, sampling and genotyping performance of such large-scale specimen need many hours, the obtained results could reflect a clear view of distribution of HCV genotypes amo...

background: physical characteristics of crops play an important role in designing the required machinery and apparatus for planting, harvesting, transport, processing and also storing. the aim of this study was to determine physical characteristics of some native rice varieties cultivated in northern iran, namely gerde, shafagh, tarom-e-hashemi, shiroodi and keshvari. methods: some geometrical,...

Objects in clutter are difficult to recognize, a phenomenon known as crowding. There is little consensus on the underlying mechanisms of crowding, and a large number of models have been proposed. There have also been attempts at unifying the explanations of crowding under a single model, such as the weighted feature model of Harrison and Bex (2015) and the texture synthesis model of Rosenholtz ...

We report an experiment designed to provide a qualitative contrast between knowledge-limited versions of mixed-state and variable-resources (VR) models of visual change detection. The key data pattern is that observers often respond “same” on big-change trials, while simultaneously being able to discriminate between same and small-change trials. The mixed-state model provides a natural account ...

dry matter remobilization, grain filling rate and duration has principle role on rice grain yield, and environment condition directly affect on them. for study the influence of climate factors a factorial field experiment in randomized complete blocks design with three replications conducted at haraz extention and technology development centre in spring 2013. treatments included rice cultivars ...

A visual system cannot process everything with full fidelity, nor, in a given moment, perform all possible visual tasks. Rather, it must lose some information, and prioritize some tasks over others. The human visual system has developed a number of strategies for dealing with its limited capacity. This paper reviews recent evidence for one strategy: encoding the visual input in terms of a rich ...
