an investigation of the impact of self monitoring on langauge teachers motivational practice and its effect on learners motivation
the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...
A Stress Analysis of Pipe Flange Connections
The use of pipe flange connections is standardized in the codes of JIS, ASME, DIN and so on. However, these codes are almost entirely dependent on experience, and subsequently some problems concerning pipe flange connections have been encountered. In the present paper, the distribution of contact stresses which governs the sealing performance is analyzed as a three-body contact problem, using a...
متن کاملDesign of Prestressed Skin–Flange Assembly
A prestressing procedure for reduction of adhesive peel and shear stresses at the leading edge of a skin–flange assembly is analyzed for tensile and bending loads applied to the skin. Both an analytical solution based on the Green’s functions and a finite element solution are presented for specific examples, together with design diagrams. Substantial shear and peel stress reductions are obtaine...
متن کاملNestling birds put their best flange forward
The offspring of caring parents may evolve specialized traits uniquely adaptive during their dependence on parental care. For example, the mouths of passerine nestlings are often bordered by enlarged and colorful rictal flanges expressed only during the nestling period. Although these traits are commonly hypothesized to act as visual signals during begging, noncommunication functions for the sp...
متن کاملStress Redistribution in Skin/Flange Assemblies
A prestressing procedure is proposed for reduction of stress concentrations at the leading edges of adhesive bondlines in composite skin/ ange assemblies. A niteelementanalysisof a speci c geometryof such an assembly is presented,whichaccounts for nonlinear viscoelastic deformation of the adhesive. Design diagrams based on elastic analysis are constructed for evaluation of prestress forces ...
