This investigation highlights the use of infrared microspectroscopy for the morphological analysis of urinary stones. The research presented here has utilized the reXectance mode of an infrared microscope for use in creating chemically speciWc maps of cross-sectioned renal calculi surfaces, precisely showing the placement of renal stone components in a calculus sample. The method has been appli...

Abstract We analyzed multiline observations of a quiescent prominence from the slit spectrograph located at Ondřejov Observatory. Dopplergrams and integrated intensity maps whole were obtained in six spectral lines: Ca ii H, H ϵ , β He i D3, α IR. By combining with non-LTE radiative-transfer modeling, we carefully identified areas an optically thin regime. The comparison Doppler-velocity scatte...

Abstract. Using OI6300 airglow images collected over São João do Cariri (7.4∘ S, 36.5∘ W) from 2000 to 2007, the equatorial plasma bubble (EPB) zonal drifts were calculated. A strong day-to-day variability was observed in EPB drifts, which is directly associated with very complex dynamics of nighttime thermosphere–ionosphere system near Equator. The present work investigated contribution semidi...

The partial oxidation of methane (POM) is a promising method for converting to syngas. transition metal supported on boron nitride (BN) has recently been studied as part catalog emerging catalysts. However, the chemical state BN during reforming still in debate. In this work, we report rhodium catalyst (Rh/BN) POM, with exceptional activity and long-term stability at 600 °C 230 h. Rh/BN was inv...
