Online Aphasia Groups: Navigating Issues of Voice and Identity.

Purpose: Participation in aphasia groups is associated with increased communication, reduced feelings of social isolation, and increased quality of life. Despite the growing popularity of online aphasia groups, little is known about how to manage conversation in this format. We examined online aphasia book club sessions to examine how the facilitator supported group members' participation in conversation.

State of the Art in Development of Heat Exchanger Geometry Optimization and Different Storage Bed Designs of a Metal Hydride Reactor.

The efficient operation of a metal hydride reactor depends on the hydrogen sorption and desorption reaction rate. In this regard, special attention is paid to heat management solutions when designing metal hydride hydrogen storage systems. One of the effective solutions for improving the heat and mass transfer effect in metal hydride beds is the use of heat exchangers.

Theoretical and Experimental Studies of Al-Impurity Effect on the Hydrogenation Behavior of Mg.

In this paper, we study the influence of hydrogen concentration on the binding energies in magnesium hydrides. The impact of aluminum atom addition on the hydrogenation behavior of magnesium was theoretically and experimentally defined. Doping Al into the Mg lattice allows the uniform hydrogen distribution in both the fcc and bcc Mg lattice at a low hydrogen concentration (H:Mg < 0.

Still Searching for Understanding: The Importance of Diverse Research Designs, Methods, and Perspectives.

Background: Evidence-based medicine and evidence hierarchies have been widely adopted and have strongly influenced decision making across many fields, including clinical aphasiology. However, questions remain about the creation, usefulness, and validity of current evidence hierarchies.

Aims: This article builds on ideas about scientific approaches and evidence originally shared by Elman (1995, 1998, 2006).

Positron Annihilation Spectroscopy Complex for Structural Defect Analysis in Metal-Hydrogen Systems.

The current work is devoted to developing a system for the complex research of metal-hydrogen systems, including in an in situ mode. The system consists of a controlled gas reactor with a unique reaction chamber, a radioisotope positron source, and a positron annihilation spectroscopy complex. The use of the system enables in situ investigation of the defect structure of solids in hydrogen sorption-desorption processes at temperatures up to 900 °C and pressures up to 50 bar.
