The influence of a supplementary bradyrhizobial inoculation after an initial seed slurry inoculation with the same strain on nodulation and N(2) fixation in soybeans was examined in the greenhouse. The plants were grown in a Typic Eutrocrepts soil: sand mixture containing 25, 65, or 83 mg of N per kg (i.e., native soil N plus N-labeled ammonium sulfate). Harvests were made at early flowering an...

UNLABELLED INTRODUCTION In slipped capital femoral epiphysis the femoral neck displaces relative to the head due to weakening of the epiphysis. Early recognition and adequate surgical fixation is essential for a good functional outcome. The fixation should be secured until the closure of the epiphysis to prevent further slippage. A slipped capital femoral epiphysis should not be confused wit...

introduction fracture - dislocations of the talus are typically due to high energy injuries. displaced fracture - dislocations of the talus have poor outcomes in general and complications are common. although talar fracture is common and comprises the second most common tarsal fracture, bilateral fracture - dislocations of the talus are rare. not many reports regarding the subject can be found ...

objective: the aim of this study was to assess skeletal relapse in patients who underwent mandibular setback by bilateral sagittal split ramus osteotomy (bssro) and osteosynthesis wiring techniques. materials and methods: in this semi-experimental study, 10 patients (8 women, 2 men) with 3-8 millimeters overjet underwent mandibular setback with bssro, osteosynthesis wiring and inter maxillary f...

BACKGROUND Tibial fixation of hamstring tendon grafts has been the weak link in anterior cruciate ligament reconstruction. HYPOTHESIS Use of a central four-quadrant sleeve and screw provides superior fixation when compared with standard interference screw fixation. STUDY DESIGN Controlled laboratory study. METHODS In eight pairs of cadaveric knees each anterior cruciate ligament was recon...

background distal radius fracture is common in all ages. mobility and wrist function is important. the choice of treatment should aim for optimal function with minimal complications. objectives in this study we compared two surgical approaches, open reduction and internal fixation (orif) and closed reduction with external fixation (cr + ef), for treatment of intra-articular distal radius fractu...

In evolutionary dynamics, a key measure of mutant trait's success is the probability that it takes over population given some initial mutant-appearance distribution. This "fixation probability" difficult to compute in general, as depends on mutation's effect organism well population's spatial structure, mating patterns, and other factors. this study, we consider weak selection, which means smal...

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...

A large amount of classic and contemporary vision studies require subjects to fixate a target. Target fixation serves as a normalizing factor across studies, promoting the field's ability to compare and contrast experiments. Yet, fixation target parameters, including luminance, contrast, size, shape and color, vary across studies, potentially affecting the interpretation of results. Previous re...

PURPOSE To document and discuss the case of a patient with left esotropia (ET) who uses the left optic nerve head (ONH) for monocular 'fixation'. CASE REPORT The patient was an 80-year-old male with left ET from early childhood. Retinal tracking monocular fixation measurements with a Nidek MP-1 revealed stable fixation within the left ONH area. In an attempt to challenge the initial observati...
