Ascertaining the lifetime distribution of a nation's buildings is critical for estimating their stock/flow. This work first study to use latest data on building stocks and inflows identify function half-life all wooden non-wooden existing in Japan from 1964 2020. The log-normal proved be most suitable function, with 38 years 1964, 56 between 1965 1996, 63 1997 On contrary, resembling exponentia...

The aim of this research is preparation of SnO2 nanowires by means of Thermal chemical reaction vapor transport deposition (TCRVTD) method from SnO powders. The morphology, chemical composition and microstructure properties of the nanowires are characterized using field emission scanning electron microscope (FE-SEM), EDS, and XRD. The XRD diffraction patterns reveal that the SnO2 nanowires have...
