… We conducted three physical performance tests (grip strength, five times sit-to-stand, and 5-meter walk tests) and the Five-Cog test (attention, memory, visuospatial, language, and reasoning). … [Results] The participants who exercised in a group had better lower limb strength than those who exercised alone and better scores for all the variables than the non-exercisers. …

… A multiscale computational framework was developed for designing CFRP wings so that even those CFRPs can be considered whose mechanical properties are not available as experimentally-measured data, thereby bridging two different scales by the following processes: 1) a microscale analysis for evaluating the mechanical properties (stiffness and strength) of unidirectional CFRP laminates and 2) a macroscale fluid-structural analysis that involves structural sizing of wingbox structures based on the mechanical properties given by the microscale analysis. …

… <p>In our previous study, it was revealed that high MF coal having longer "maximum permeation distance", which was developed as a unique thermoplasticity index, forms lower roundness pores and thinner pore-wall structures in coke and that coke strength deteriorated when the coal blend included the longer maximum permeation distance coal. … Therefore, techniques for reducing the adverse effects of long maximum permeation distance coal on coke strength are essential so as to utilize the coal more efficiently. …

… <p>In the present study, we prepare several types of specimens from non-caking coal – including specimens in which noncovalent bonds between O-functional groups in coal are cleaved by pyridine and HPC-derived thermoplastic components are introduced into the pores produced by swelling, as well as specimens consisting of physical blends with HPC – and examine the influence of heating conditions and types of caking agents on the production of high-strength coke using a SUS tube. …

… <p>In this study, the effect of anodization and electroless Ni–P plating on the fatigue strength of commercial A5052-H14 and A2017-T4 aluminum alloys was investigated. … Anodization led to a slight increase in the fatigue strength of the A2017-T4 alloy of approximately 10% because of the suppression of the generation of fatigue crack, and anodization with a 5-µm thickness for A5052-H14 also led to a slight increase in the fatigue strength. …
