Reversed liquid crystalline mesophases, such as the reversed bicontinuous cubic, reversed hexagonal or reversed micellar cubic phase, are nowadays widely studied due to their potential applications in, for instance, the controlled delivery of functional molecules. In order to design the adequate mesophase delivery system for a specific application, the crystallographic structure of the phase ha...

The optical properties (absorption and fluorescence) of fluorescein sodium were investigated with changing the bulk pH value in aqueous, water-methanol mixed and dodecylammonium propionate reversed micellar solutions. A strong buffer action was found in the reversed micellar solutions. The pK a values for the equilibrium between fluorescein monoand di-anions in the ground and excited singlet st...

An 85-year-old lady with decreased mood and low energy was found to have an elevated serum corrected calcium concentration of 2.8mmol/L (reference range: 2.1–2.6mmol/L). Plasma parathyroid hormone concentration was elevated at 390 pg/mL (reference range: 10–85 pg/mL). She had a past history of renal calculi. Renal function, full blood picture, erythrocyte sedimentation rate, 24-h urinary calciu...

Although bimachines are not widely used in practice, they represent a central concept in the study of rational functions. Indeed, they are finite state machines specifically designed to implement rational word functions. Their modelling power is equal to that of single-valued finite transducers. From the theoretical point of view, bimachines reflect the decomposition of a rational function into...
