Abstract: The Exercise Joins Education: Combined Therapy to Improve Outcomes in Newly-discharged Heart Failure (EJECTION-HF) study will evaluate the impact of a supervised exercise training programme (ETP) on clinical outcomes in recently hospitalized heart failure patients attending a disease management programme (DMP). Methods This multisite, pragmatic randomized controlled trial enrols patients discharged from participating hospitals with clinical evidence of heart failure who are willing and able to participate in a DMP and considered clinically safe to exercise. Enrolment includes participants with impaired and preserved left ventricular systolic function. Baseline assessment and programme commencement occur within 6 weeks of hospital discharge. The control group DMP includes in idualized education and follow-up from a multidisciplinary heart failure team a weekly education programme for 12 weeks self-management advice and medical follow-up. Home exercise is recommended for all participants. In addition, intervention participants are offered 36 supervised, structured gym-based 1 h exercise sessions over 24 weeks. Sessions are tailored to exercise capacity and include aerobic, resistance, and balance exercises. Enrolment target is 350 participants. Primary outcome is 12-month mortality and readmissions. Secondary outcomes include blinded evaluation of depressive symptoms, sleep quality, cognition, and functional status (activities of daily living, 6 min walk distance, grip strength) at 3 and 6 months. A cost-utility analysis will be conducted. This study will enrol a representative group of hospitalized heart failure patients and measure a range of patient and health service outcomes to inform the design of post-hospital DMPs for heart failure. Enrolment will be completed in 2013. ACTRN12608000263392.

Abstract: We report the fabrication and characterization of a Mg-based metal matrix composite reinforced by MgO ceramic and Mg–Mg 2 Cu eutectic. The composite was fabricated by sintering and quenching of a Mg–20 wt.% CuO s le. We performed differential scanning calorimetry (DSC) on the s le and found that the reaction between Mg and CuO took place at about 420 °C. When the s le was sintered to 550 °C and cooled down, the two-phase Mg–Mg 2 Cu eutectic formed. The final composite product contained MgO particles and Mg–Mg 2 Cu eutectic, which were embedded in the Mg matrix. Based on the results from DSC and scanning and transmission electron microscopies, a model is proposed to describe the competitive growth of Mg and the eutectic during solidification. We also found that the microstructure of the Mg–Mg 2 Cu eutectic strongly depended on the rate of cooling. The lamellar thickness of the eutectic could be reduced to 120 nm by oil-quenching the sintered s le.

Abstract: Two materials currently of interest for onboard lightweight hydrogen storage applications are sodium aluminum hydride (NaAlH 4 ), a complex metal hydride, and carbon aerogels (CAs), a light porous material connected by several spherical nanoparticles. The objectives of the present work have been to investigate the synthesis, characterization, and hydrogenation behavior of Pd-, Ti- or Fe-doped CAs, NaAlH 4 , and MgH 2 nanocomposites. The diameters of Pd nanoparticles onto CA’s surface and BET surface area of CAs were 3–10 nm and 700–900 m 2 g −1 , respectively. The H 2 storage capacity of metal hydrides has been studied using high-pressure TGA microbalance and they were 4.0, 2.7, 2.1, and 1.2 wt% for MgH 2 -FeTi-CAs, MgH 2 -FeTi, CAs-Pd, and 8 mol% Ti-doped NaAlH 4 , respectively, at room temperature. Carbon aerogels with higher surface area and mesoporous structures facilitated hydrogen diffusion and adsorption, which accounted for its extraordinary hydrogen storage phenomenon. The hydrogen adsorption abilities of CAs notably increased after inclusion of metal hydrides by the “hydrogen spillover” mechanisms.

Abstract: This work investigates the dehydrogenation of TiH 2 powder during isothermal heating at 600°C using the static x-ray scans of high temperature x-ray diffraction (XRD). As-received TiH 2 powder with a particle size of 5 μm and purity of 99.1% was used for this measurement. With increasing temperature, phase transformations occurred because of dehydrogenation and it happened very fast. It was found that during the phase transformation of TiH 2 to titanium, some transitional phases observed and occurred. This finding confirmed the in-situ determination of TiH 2 powder dehydrogenation by using Rietveld Refinement Method from our previous research. This study is useful for the fabrication of titanium-based composites and titanium alloys from TiH 2 powder because the different phases in TiH 2 will affect the final mechanical properties in titanium.
