UNLABELLED Although only recently described, Colletotrichum boninense is well established in literature as an anthracnose pathogen or endophyte of a diverse range of host plants worldwide. It is especially prominent on members of Amaryllidaceae, Orchidaceae, Proteaceae and Solanaceae. Reports from literature and preliminary studies using ITS sequence data indicated that C. boninense represents ...
in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...
psychometric properties of automatic thoughts questionnaire and investigation of the relationship between automatic thoughts with cognitive emotion regulation and self regulated learning
Correlation between Continuous/Discontinuous Yielding and Hall–Petch Slope in High Purity Iron
the present study aimed at investigating the relationship between iranian efl teachers’ classroom management orientations and their teaching styles. additionally, the difference between male and female teachers’ teaching styles and classroom management orientations and their relationship with experience and age were explored. three hundred efl teachers filled in attitudes and beliefs on classro...
2 Viewpoint : experimental recovery of geometrically 3 necessary dislocation density in polycrystals
8 Abstract 9 Application of electron backscattering diffraction methods to recover estimates of the geometrically necessary dis-10 location density is described. The limitations of the method arising from the opacity of crystalline materials and the 11 spatial and angular resolution limits are discussed. 15 It has long been an experimental observation 16 that the constituent grains of polycryst...
Nanocrystalline (NC) metals with grain sizes <100 nm have attracted a lot of attention in the materials science fi eld for more than a few decades because of their ultra-high strength and hardness. Various experimental and computational studies indicate that dislocation-mediated plasticity prevails in NC metals when the grain size is larger than ~10 nm. Recent molecular dynamics (MD) simulation...
Ultrafine-grained (UFG) metallic materials processed by severe plastic deformation (SPD) techniques often exhibit significantly higher strengths than those calculated the well-known Hall-Petch equation. These result from fact that SPD processing not only forms UFG structure but also leads to formation of other nanostructural features, including dislocation substructures, nanotwins and nanosized...
