Catalytic and spectroscopic properties of alcohol dehydrogenase from horse liver, incorporated in reversed micellar media, have been studied. Two different reversed micellar systems have been used, one containing an anionic [sodium bis(2-ethylhexyl)sulfosuccinate, AOT], the other containing a cationic (cetyltrimethylammonium bromide, CTAB) surfactant. With 1-hexanol as substrate the turnover nu...

Principia Logico-Metaphysica proposes a foundational logical theory for metaphysics, mathematics, and the sciences. It contains a canonical development of Abstract Object Theory [AOT], a metaphysical theory (inspired by ideas of Ernst Mally, formalized by Zalta) that differentiates between ordinary and abstract objects. This article reports on recent work in which AOT has been successfully repr...

Cel Celem podjętych badań było opracowanie polskiej wersji kwestionariusza do pomiaru myślenia otwartego (Actively Open-minded Thinking, AOT). Kwestionariusz pozwala ocenić dyspozycję rozważania analizowanych problemów z różnych punktów widzenia, bez względu na pierwotnie faworyzowane opcje, oraz krytyczną postawą wobec stosowanych reguł analizy informacji i formułowania wniosków. Metoda Badani...

Effect of compressed CO2 on properties of the sodium bis(2-ethylhexyl) sulfosuccinate (AOT)/isooctane/water reverse micellar solution has been studied by phase behavior measurement. UV-vis study indicates that TiO2 in the reverse micelles can be precipitated by compressed CO2 at suitable pressures, while the surfactant AOT remains in the solution. Using this concept, TiO2 nanoparticles synthesi...

The effect of hydrotropes on the geometry of reverse water-in-oil AOT-microemulsions is investigated as a function of water content, and hydrotrope additive architecture. SANS reveals that hydrotropes induce cylindrical morphologies which transition to ellipsoidal and then spherical geometries with increasing water content (w). The length of the elongated particles appeared to show some depende...

Aerosol extinction profiles are derived from backscatter data by constraining the retrieval with column aerosol optical thickness (AOT), for example from coincident MODIS observations and without reliance on a priori assumptions about aerosol type or optical properties. The backscatter data were acquired with the NASA Langley High Spectral Resolution Lidar (HSRL). The HSRL also simultaneously m...

The aerosol optical thickness (AOT) over the region of Baikal was retrieved using the MODIS data and the V5.2 algorithm developed by NASA. The results were validated by the CE-318 observations. Though the R2 is not that high, the result could display the spatial distribution of aerosol. The AOT characteristics of spatial and temporal variation over the region of Baikal were analyzed: The mean A...

The fluorescence characteristics of norfloxacin (NFLX) were studied in reversed micelles which formed with sodium bis(2-ethylhexyl) sulfosuccinate (AOT)-water-octane. The influences of the environmental factors, such as the water content, AOT concentration and pH, on the fluorescence of NFLX were investigated. A novel spectrofluorimetric method for the direct determination of NFLX is proposed b...
