The consolidation of single antigen beads (SAB-panIgG) assay in the detection of preformed anti-human leukocyte antigen (HLA) antibodies has improved transplantation success. However, its high sensitivity has limited the allograft allocation for sensitized patients, increasing their waiting time. A modification of the standard SAB-panIgG assay allows the detection of that subset of antibodies c...
This paper investigated the effects of combining fibers with self-consolidating concrete (SCC). 12 series of test specimens were prepared using three kinds of fibers including steel, polyphenylene sulfide (PPS) and glass fibers with four different volumes fractions and one specimen without fibers as a reference sample. All plans were subjected to fresh concrete tests. For mechanical behavior of...
introduction: to recognize the myelinated nerve fibers of the external capsule in human brain. materials and methods: 10 adult and normal brains (20 hemispheres) from both sexes were studied using 15 mm serial sections in all three cardinal planes after fixation and processing. these sections were stained by klüver - barrera and heidenhain - woelcke methods. results: some fibers from different ...
[1] The preformed nitrate distribution throughout the subtropical North Pacific is characterized by a negative anomaly between 100 m and the 25.4 sq surface. Its presence indicates that nitrogen remineralization in the upper thermocline deviates significantly from Redfield stoichiometry. It has been previously suggested that this feature is created during the degradation of nitrogen-poor dissol...
Persimmon byproduct upcycling was performed by solvent-assisted extraction (SAE) to obtain dietary fiber (DF). The effect of SAE on DF modulation studied specific beneficial and pathogenic strains before after the in vitro digestion process. Overall, digested samples extracted using acetone as a solvent (dCET) showed higher ( p < 0.05) prebiotic activity scores (PASs) bacteria such Bifidobacter...

The continuity and thickness of the coating layer, are the most important factors in wetting properties and strength of carbon fibers. These factors are crucial in the quality of metal matrix composites made with carbon fibers. In this research the Polyacrylonitrail base carbon fibers have been nickel coated with 0.2, 0.5, 0.8 and 11 ,u in thickness, by the electroless method. The effect of the...
statement of the problem: the stability of orthodontic treatment depends on preserving the patient’s pretreatment arch form and arch size during and after treatment. purpose: this investigation was aimed to study the size and shape of iranian mandibular dental arch and evaluate the correlation of their average dental arch with commercially available preformed rectangular nickel-titanium arch wi...
