A chimeric plant was observed in the F(2) generation of a cross between a male-sterile line and a plant introduction homozygous for a chromosome interchange in soybeans [Glycine max (L.) Merr.]. F(3) progeny of this plant included one chimera, 36 yellow plants and 16 green plants. The yellow plants, which progressively turn green, were viable and fertile in field, greenhouse and growth-chamber ...

THE JOINT surveillance and target attack radar system (JSTARS) promises to revolutionize how US forces conduct conventional warfare. Before the development of JSTARS, US forces de­ pended on close operations to defeat an enemy army. Because airpower’s ability to destroy an enemy’s mo­ bile ground forces was severely limited, especially during darkness and bad weather, interdiction proved import...

to evaluate the reaction of some wheat advanced lines and cultivars to yellow rust at seedling stage, seeds of 200 accessions were planted in 5cm diameter pots (4-6 seeds per pot) in greenhouse. the seedlings were inoculated with fresh harvested urediniospores of two different races of puccinia striiformis f.sp. tritici (134e134a+ from karaj and 134e142a+ from maragheh, iran) when the first see...

introduction: there has been an increasing interest in studies dealing with the relationship between mental disorders and color preference. this study was tailored to evaluate color preference or rejection in schizophrenic and normal subjects. materials and method: color preference and rejection of 58 patients with dsm-iv diagnosis of schizophrenia were compared with those of 52 normal subjects...

The exotic zebra mussel, Dreissena polymorpha, is established in all of the Laurentian Great Lakes and may affect benthivorous fishes by increasing the complexity of benthic substrates and changing energy flow patterns within the food web. Native yellow perch, Perca flavescens, and the nonindigenous Eurasian ruffe, Gymnocephalus cernuus, are benthivores that may compete for limited food resourc...

purpose : to determine the distribution of iris colors in the population of tehran and to assess possible associations between iris color and ocular disorder methods : through a stratified random cluster sampling approach, 160 clusters were selected in different municipality districts of tehran, and the approached households were invited to a clinic. after the initial interview, all participant...

In congenital color blindness the red-green discrimination is impaired resulting in an increased confusion between those colors with yellow. Our post-receptoral physiological mechanisms are organized in two pathways for color perception, a red-green (protanopic and deuteranopic) and a blue-yellow (tritanopic). We argue that the discrimination losses in the yellow area in congenital color vision...

INTRODUCTION Color processing is a central component of mammalian vision. Gender-related differences of color processing revealed by non-invasive functional transcranial Doppler ultrasound suggested right hemisphere pattern for blue/yellow chromatic opponency by men, and a left hemisphere pattern by women. MATERIALS AND METHODS The present study measured the accumulation of [18F]fluorodeoxygl...

Sunglasses are intended to protect the eye from damage caused by exposure to wavelengths both within the visible spectrum and outside the visible spectrum. Effective sunglass lenses use a combination of darkness and wavelength filtering (color) to reduce brightness and glare and to protect eyes from damaging UVR. Various factors should be considered in assessing the effectiveness of sunglasses,...

The role of the autonomic nervous system (ANS) was recently investigated in Temporomandibular disorders (TMD). Several authors argue that in subjects with TMD there is a dysregulation of ANS. Recent literature support that Pupillometry is a simple non-invasive tool to study ANS. The aim of this study was to investigate the relationship between TMD and ANS activity using pupillometry recording i...
