the effects of partial substitution of La by Ce and Ni by Al, Fe, or Co in LaNi_5-based alloys on hydrogen storage performance were systematically studied. All samples were prepared using vacuum arc melting in an argon atmosphere. the results showed that for LaNi_(5-x)M_x(M = Al, Fe, or Co) alloys, the lattice constants and unit cell volumes increased with an increasing amount of Al and Fe. On the other hand, these parameters decreased upon partial substitution of La by Ce. In addition, the lattice constant remained almost constant in the La_(0.6)Ce_(0.4)Ni_(5–x)Cox alloys regardless of the value of x(x = 0.3, 0.6, or 0.9), as Ce might enhance the homogeneity of the CaCu_5-type phase in Co-containing alloys. the hydrogen storage properties of the alloys were investigated using pressure, composition, and temperature isotherms. the experimental results showed that the plateau pressure decreased with an increasing content of Al, Fe, or Co, but it increased with Ce addition. Furthermore, the plateau pressures of all Co-containing alloys were almost identical upon substitution with Ce. Finally, the enthalpy(ΔH) and entropy(ΔS) values for all alloys were calculated using van't Hoff plots. the relationship between the lattice parameters and enthalpy changes for hydrogenation will be discussed.

Open Journal of therapy and Rehabilitation 2022年第4期10卷 244-256页

作者： takashi kimura Department of Physical therapy ASO Rehabilitation College Fukuoka Japan Department of Rehabilitation Medicine Saga University Hospital Saga Japan

Background and Purpose: to investigate target functional independence measure (FIM) items to achieve the prediction goal in terms of the causal relationships between prognostic prediction error and FIM among stroke patients in the convalescent phase using the structural equation modeling (SEM) analysis. Methods: A total of 2992 stroke patients registered in the Japanese Rehabilitation Database were analyzed retrospectively. the prediction error was calculated based on a prognostic prediction formula proposed in a previous study. An exploratory factor analysis (EFA) then the factor was determined using confirmatory factorial analysis (CFA). Finally, multivariate analyses were performed using SEM analysis. Results: the fitted indices of the hypothesized model estimated based on EFA were confirmed by CFA. the factors estimated by EFA were applied, and interpreted as follows: “transferring (t-factor),” “Dressing (D-factor),” and “Cognitive function (C-factor).” the fit of the structural model based on the three factors and prediction errors was supported by the SEM analysis. the effects of the D- and C-factors yielded similar causal relationships on prediction error. Meanwhile, the effects between the prediction error and the t-factor were low. Observed FIM items were related to their domains in the structural model, except for the dressing of the upper body and memory (p transfer, which was not heavily considered in the previous prediction formula, was found in causal relationships with prediction error. It is suggested to intervene to transfer together with positive factors to recovery for achieving the prediction goal.
