Raman and infrared spectra of three well-defined turquoise samples, CuAl6(PO4)4(OH)8·4H2O, from Lavender Pit, Bisbee, Cochise county, Arizona; Kouroudaiko mine, Faleme river, Senegal and Lynch Station, Virginia were studied, interpreted and compared. Observed Raman and infrared bands were assigned to the stretching and bending vibrations of phosphate tetrahedra, water molecules and hydroxyl ion...
We suggest a rigorous theory of how objective single-case transition probabilities fit into our world. The theory combines indeterminism and relativity in the ‘‘branching space–times’’ pattern, and relies on the existing theory of causae causantes (originating causes). Its fundamental suggestion is that (at least in simple cases) the probabilities of all transitions can be computed from the bas...
We describe a blue/green inorganic material, Ba3(P1−xMnxO4)2 (I) based on tetrahedral MnO3− 4 :3d 2 chromophore. The solid solutions (I) which are sky-blue and turquoise-blue for x ≤ 0·25 and dark green for x ≥ 0·50, are readily synthesized in air from commonly available starting materials, stabilizing the MnO3− 4 chromophore in an isostructural phosphate host. We suggest that the covalency/ion...
Steam methane reforming with CO2 capture (blue hydrogen) and water electrolysis based on renewable electricity (green are commonly assumed to be the main supply options in a future hydrogen economy. However, another promising method is emerging form of natural gas pyrolysis (turquoise pure carbon as valuable by-product. To better understand potential turquoise hydrogen, this study presents tech...
1. A number of reactive triazine dyes specifically and irreversibly inactive yeast hexokinase at pH 8.5 and 33 degrees C. Under these conditions, the enzyme is readily inactivated by 100 microM-Procion Green H-4G, Blue H-B, Turquoise H-7G and Turquoise H-A, is less readily inactivated by Procion Brown H-2G. Green HE-4BD, Red HE-3B and Yellow H-5G and is not inactivated at all by Procion Yellow ...
Due to the lack of potential organs, hepatocellular transplantation has been considered for treating end-stage liver disease. Induced pluripotent stem cells (iPSCs) are reverted from somatic cells and are able to differentiate into hepatocytes. The present study aimed to investigate the mechanisms underlying iPSC differentiation to hepatocytes. GSE66076 was downloaded from the Gene Expression O...
BACKGROUND Direct-acting antivirals (DAAs) against hepatitis C virus (HCV) have been described as revolutionary. However, it remains uncertain how effective these drugs will be for individuals coinfected with human immunodeficiency virus (HIV)-HCV. Bridging this gap between efficacy and effectiveness requires a focus on the generalizability of clinical trials. METHODS Generalizability of DAA ...
