the evolution of texture was discussed during the formation of ultra-fine and nano grains in a magnesium alloy severely deformed through accumulative back extrusion (abe). the microstructure and texture obtained after applying multiple deformation passes at temperatures of 100 and 250°c were characterized. the results showed that after single abe pass at 100°c an ultrafine/nano grained microstr...

We investigated whether young infants orient reliably towards more salient vs. less salient objects in a visual scene. Subjects were tested with stimuli presented on textured fields, one side showing a target stimulus (a 'more salient' or 'less salient' texture patch) and the other a background stimulus. Infants typically preferred the more salient, but not the less salient target. Their behavi...

OBJECTIVE Obesity is a growing epidemic and public health problem in children. The purpose of this study was to determine the effect of body mass index (BMI) on the gross motor development. MATERIALS & METHODS In this cross-sectional study conducted in 2012-13 in Gorgan, northern Iran, the gross motor development of 90 children 3-5 yr old in three groups of lean, normal and obese/overweight w...

background: toxoplasma gondii is one of the most prevalent parasites of human and warm- blooded animals. toxoplasmosis is important especially in two groups: pregnant women and immunocompromised patients. if women acquire the primary infection during the pregnancy, it would be life threatening or re-mains severe disorders for the fetus. this study was performed to evaluate the seroprevalence of...

Texture has been recognized as an important visual primitive in image analysis. A widely used texture descriptor, which is part of the MPEG-7 standard, is that computed using multiscale Gabor filters. The high dimensionality and computational complexity of this descriptor adversely affect the efficiency of content-based retrieval systems. We propose a modified texture descriptor that has compar...

SPOT panchromatic imagery of Beijing has been studied to capture the unique spatial pattern of the city. Texture analysis, which reveals spatial variations, was adopted to interpret the urban spatial patterns. Statistical and structural texture features were extracted from the SPOT image and evaluated for their capability of detailed mapping of urban structures. Supervised image classifications...

in order to achieve high quality seeds, producers must be able to estimate the accurate harvest maturity time seeds. the objective of this study was to investigate changes in seed quality during seed development and maturation in the two cultivars native of the sari and gorgan and two cultivars modified of the darab14 and yellowhite. a field experiment was conducted in during 2009 at gorgan uni...

INTRODUCTION A cleft lip with or without a cleft palate is one of the major congenital anomalies observed in newborns. This study explored the risk factors for oral clefts in Gorgan, Northern Iran. MATERIALS AND METHODS This hospital-based case-control study was performed in three hospitals in Gorgan, Northern Iran between April 2006 and December 2009. The case group contained 33 newborns wit...
