TL;DR: In this article, a new family of PEO-based SPEs containing potassium hydroxide and water was thoroughly investigated in order to better understand the structure of these materials and to relate it with the interesting conducting properties observed.

TL;DR: In this article, a weighted residual-based approach for the numerical investigation of the interaction of fluid flow and thin flexible structures is introduced. But the method is limited to the case of strongly coupled fluid-structure systems.
Abstract: The paper introduces a weighted residual-based approach for the numerical investigation of the interaction of fluid flow and thin flexible structures. The presented method enables one to treat strongly coupled systems involving large structural motion and deformation of multiple-flow-immersed solid objects.
The fluid flow is described by the incompressible Navier–Stokes equations. The current configuration of the thin structure of linear elastic material with non-linear kinematics is mapped to the flow using the zero iso-contour of an updated level set function. The formulation of fluid, structure and coupling conditions uniformly uses velocities as unknowns. The integration of the weak form is performed on a space–time finite element discretization of the domain. Interfacial constraints of the multi-field problem are ensured by distributed Lagrange multipliers. The proposed formulation and discretization techniques lead to a monolithic algebraic system, well suited for strongly coupled fluid–structure systems. Embedding a thin structure into a flow results in non-smooth fields for the fluid. Based on the concept of the extended finite element method, the space–time approximations of fluid pressure and velocity are properly enriched to capture weakly and strongly discontinuous solutions. This leads to the present enriched space–time (EST) method. Numerical examples of fluid–structure interaction show the eligibility of the developed numerical approach in order to describe the behavior of such coupled systems. The test cases demonstrate the application of the proposed technique to problems where mesh moving strategies often fail. Copyright © 2007 John Wiley & Sons, Ltd.

TL;DR: In this paper, the authors highlight four main tensions that emerge from strategists' discourses on strategizing work: social tension, cognitive tension, focus tension, and time tension.
Abstract: Until recently, the field of strategy has neglected the question of what it means to be a strategist. Based on an analysis of 68 interviews with strategy practitioners, our results highlight four main tensions that emerge from strategists' discourses on strategizing work: the social tension, the cognitive tension, the focus tension, and the time tension. This tension-based representation of strategy enables us to differentiate between three forms of strategists' subjectivities, i.e. the ways by which strategists discursively cope with tensions as a means of constituting their identity and legitimacy: the mythicizing subjectivity, the concretizing subjectivity, and the dialogizing subjectivity. Such results shed light on what a strategist is, suggesting that strategizing can be conceptualized as the art of balancing tensions and that multiple strategists' subjectivities within a paradox lens on strategy may in fact co-exist.

TL;DR: In conclusion, CE prognosis remains poor, with a better outcome among younger patients and intravenous drug users, and Detection of serum antigens and molecular tools may contribute to earlier CE diagnosis.

TL;DR: In this article, the helium and oxygen gas barrier properties of poly(lactide) were investigated as a function of stereochemistry and crystallinity degree, and it was shown that the gas permeability increased with increasing quantity of α-crystals in poly(n,l-lactides) and remained constant with increasing number of α−−−crystals.
