Background and purpose: Pesticide residues in food products is of great concern. Food preparation highly influences the pesticide residue and safety of the food. The aim of this study was to evaluate the effects of storage and different washing solutions on dichlorvos residue in tomato. Materials and methods: A Interventional study was performed in which tomato samples were harvested after 2...
In this article I would present evidence to show that timing of the flow of neural signals within the ventral visual stream is a crucial part of the neural code for categorization of faces. We recorded the activity of 554 inferotemporal neurons from two macaque monkeys performing a fixation task. More than 1000 object images including human and non-primate animal faces were presented up to 10 t...
Field Ion Microscopy (FIM) and Scanning Tunneling Microscopy (STM) have found a wide application in nanotechnology. These microscopes use a metallic nanotip for image acquisition. Resolution of FIM and STM images depends largely on the radius of nanotip apex; the smaller the radius the higher the resolution. In this research, for tungsten nanotip fabrication, electrochemical etching of tungsten...
abstract this study aimed at analyzing a corpus of emails gathered from iranian students studying in england. the corpus contained 996 emails that were investigated by employing the framework of chen (2006) to find common patterns in the discourse of these emails. another aim of the study was to find how two request acts (want statements and query preparatory) were used in the emails. the...
Introduction: The purpose of this study was to investigate the effect of flask investment materials on the color changes of different brands of resin denture teeth. Methods: Resin denture teeth (560) were divided into 2 groups according to the materials used for flask investment (silicone or gypsum). All the specimens were thermocycled between 4°C and 60°C with 60-s dwell times for 1,000 cycles...
in this study brown algae, sargassum glaucescens and that found plenteously in persian gulf and bushehr coast, were collected and hot water extracts of them were lyophilized. f. indicus (11.32±1.20 g), after two weeks adaptation in shoghab research station dependent to iran shrimp research center, isrc, were immersed in seawater (39 ppt and 25±1 c○) containing hot-water extract of brown algae, ...

The relationship of the renin--angiotensin--aldosterone axis with renal prostaglandin E is complex. Although studies have suggested that these two hormonal systems respond to experimental manipulations in a parallel manner, their interdependence has not been assessed fully during volume expansion. Since studies have demonstrated that in normal man the central hypervolaemia induced by water imme...
