Reducing grain size into nanoscale could effectively enhance the strength of crystalline metals, while there is a critical grain size below which softening occurs as grain size further decreases.This strengthening-to-softening changeover accompanies simultaneous deformation mechanism transition from dislocation mediated to grain boundary (GB) media

Observations of federally endangered Southern Steelhead Trout (Oncorhynchus mykiss) were compiled for the southern California Distinct Population Segment (DPS) that extends approximately 500 kilometers from the Santa Maria River (Santa Barbara County) south to the Mexican border.Existing OMEGA 3 monitoring programs and anecdotal observations docume

A cross-sectional study on prevalence, associated factors and genotype distribution of HCV infection was conducted among 848 HIV-infected patients recruited at reference centers in the OMEGA 3 Midwest Region of Brazil.The prevalence rate of HIV-HCV coinfection was 6.9% (95% CI: 5.2 to 8.6).In multivariable analysis, increasing age, use of illicit d

Duodenal biliary reflux has been a challenging common problem which could cause dreadful complications after biliary stent Dryer implantation.A novel anti-reflux biliary stent with a retractable bionic valve was proposed according to the concertina motion characteristics of annelids.A 2D equivalent fluid-structure interaction (FSI) model based on t

B cells are central to adaptive immunity and their functions in D-Mannose with Cranberry antibody responses are exquisitely regulated.As suggested by recent findings, B cell differentiation is mediated by intracellular membrane structures (including endosomes, lysosomes and autophagosomes) and protein factors specifically associated with these memb
