Traits related to nitrogen fixation may be used as indirect selection criteria foraflatoxin resistance in peanut. The aim of this study was to investigate therelationship between N2 fixation traits and aflatoxin contamination in peanut underdifferent drought conditions. Eleven peanut genotypes were evaluated under threewater regimes for two seasons in the field. Data were observed on kernel inf...

Patellar fracture is a common injury caused by excessive tension through the extensor mechanism or a direct blow. The intact patella increases the leverage and efficiency of the extensor mechanism and articulates with the femoral trochlea. Patellar fractures can lead to stiffness, extension weakness, and patellofemoral arthritis. Nonsurgical management is indicated for nondisplaced fractures wi...

Unbalanced production of atmospheric CO(2) constitutes a major challenge to global sustainability. Technologies have thus been developed for enhanced biological carbon fixation (also referred to as CO(2) mitigation), and one of the most promising capitalizes on microalgae. However, the "best bioreactor", which would be able to achieve maximum productivity and maximum energy efficiency under a g...

Cyanobacteria are photosynthetic bacteria with a unique CO2 concentrating mechanism (CCM), enhancing carbon fixation. Understanding the CCM requires a systems level perspective of how molecular components work together to enhance CO2 fixation. We present a mathematical model of the cyanobacterial CCM, giving the parameter regime (expression levels, catalytic rates, permeability of carboxysome s...

in order to study the biological fixation efficiency of different strains of symbiosis bacteria in three varieties of common bean (phaseolus vulgaris l.) a factorial experiment based on randomized complete block design was conducted in zanjan province during 2006 and 2007. in this investigation three strains of rizobium including: rb117 (extracted from the zanjan soils), rb123 (extracted from t...

The extent of biological CO2 fixation was evaluated for outdoor cultures of the cyanobacterium Anabaena sp. ATCC 33047. Culture conditions were optimized indoors in bubble-column photochemostats operating in continuous mode, subjected to irradiance cycles mimicking the light regime outdoors. Highest values achieved for CO2 fixation rate and biomass productivity were 1 and 0.6 g L(-1) day(-1), r...

This study was designed to compare tissue preservation efficiency of formaldehyde substitution (FS) on cryosections with acetone (AC) and formaldehyde (FA). Brain, kidney, heart and liver had obtained from adult Dutch rabbit and were fixed with either FA or FS and AC prior to cryosectioning. Hematoxylin and eosin staining showed that AC is a poor fixative in preserving the general tissue and ce...

A biologically inspired foveated attention system in an object detection scenario is proposed. Thereby, a highperformance active multi-focal camera system imitates visual behaviors such as scan, saccade and fixation. Bottom-up attention uses wide-angle stereo data to select a sequence of fixation points in the peripheral field of view. Successive saccade and fixation of high foveal resolution u...

Rhizobium microbial bacteria functioning that living a symbiosis relationship soil and leguminous plant root fixation of nitrogen to be utilized by superior performance during grain development stage. They can enter into with plant, infecting their nodules. The legume crops are the bigger partner, often referred as macro-symbiotic. Usually certain strains form nodule on limited plants. Such col...
