One of the most popular forming processes is the shape rolling process in which the desired shape change is achieved by pressing two rollers with a special shape in the opposite rotational direction. In order to improve the product’s quality and reduce production costs, accurate analysis of the shape rolling process of the compressor blades as well as the investigation of the effective paramete...
background and aims. gingival recession (gr), a common problem in periodontium, is associated with various etiologic factors. there is controversy over the role and importance of these factors. the aim of this study was to evaluate the etiologic factors of gr in a group of subjects in northwest iran. materials and methods. in this case-control study, patients referring to a university clinic (1...
This study was conducted to evaluate the genetic diversity of sugar beet half sib inbred lines (48 lines and one control cultivar) under water stress (200mm of class A evaporation pan) in field conditions in a randomized complete block design with three replicates in Khorasan Razavi Agricultural and Natural Resources Research and Education Center in 2015. In this research, traits such as root y...
Mathematical models based on dynamic growth process of greenhouse melon leaves were built. Two experiments, involving different years, organic fertilizer rates and cultivar types in melon, were carried out for data acquisition. In each experiment, time-course observations of leaf morphological properties (leaf length and leaf width) on different leaf positions of melon were obtained. The result...
In order to study the effects of different irrigation regimes and different levels of salinity on the growth parameters of Quinoa (Chenopodium quinoa Willd.), this experiment was performed in the research green house of Water Engineering Department, at f Gorgan University of Agricultural Sciences and Natural Resources, during 2016. The experimental design was a factorial with n a randomized com...
Article type: Original Article Introduction: Geometric changes in the multileaf collimator (MLC) led to dosimetric considerations in intensity-modulated radiation therapy (IMRT) due to the number and size of the pixels in the intensity map, which are determined by the MLC leaf width. In this study, we evaluated the dosimetric effects of different MLC widths on physical dose distributions for IM...
This study was carried out in order to examine the contrastive relationship between seed yield and agro-morphological traits in confectionery sunflowers at molecular and phonotypical level via association mapping and sequential path model. In this study, 50 confectionery sunflower populations gathered from different regions of country were studied in completely randomized design with ten replic...
in order to investigate the water deficit impact on physical characteristics of seed in four sunflower hybrids (azargol, allstar, hysun 33 and hysun25), under three irrigation regimes (irrigation after 50, 100 and 150 mm cumulative evaporation from class a evaporation pan, respectively) and experiment was conducted. sampling was done at the end of growing period (season) when the moisture conte...
Leaf thickness is a quantitative trait that is associated with the ability of plants to occupy dry, high irradiance environments. Despite its importance, leaf thickness has been difficult to measure reproducibly, which has impeded progress in understanding its genetic basis, and the associated anatomical mechanisms that pattern it. Here, we used a custom-built dual confocal profilometer device ...
