We develop a possibilistic semantic formalism for quantum phenomena from an operational perspective. This system is based on Chu duality between preparation processes and yes/no tests, the target space being three-valued set equipped with informational interpretation. A basic of axioms introduced states. suffices to constrain states be projective domain. The subset pure then characterized withi...

BACKGROUND/AIMS Erythropoietin-resistance is an unsolved concern in the treatment of renal anaemia. We aimed to investigate the possible role of ortho- and meta-tyrosine - the hydroxyl free radical products of L-phenylalanine - in the development of erythropoietin-resistance. METHODS TF-1 erythroblast cell line was used. Cell concentration was determined on day 1; 2 and 3 by two independent o...

In the field of cobalt(II) porphyrin-catalyzed metallo-radical reactions, organic azides have emerged as successful nitrene transfer reagents. In the pursuit of employing ortho-YH substituted (Y = O, NH) aryl azides in Co(II) porphyrin-catalyzed nitrene transfer reactions, unexpected hydrogen atom transfer (HAT) from the OH or NH₂ group in the ortho-position to the nitrene moiety of the key rad...

Digital ortho-images provide great advantages in comparison to their analogue counterparts, especially with respect to flexibility, production of derived products and combination with other data sets. Today, production of digital ortho-images has become more operational due to the development of more powerful computers with sufficient resources, easier acquisition of input data, increased gener...
