This study reports the direct production of an aluminium–manganese alloy during aluminium electrolysis in fluoride-based melts. Experiments were conducted a laboratory cell dedicated for current efficiency measurements. The temperature was varied from 965–980 °C at cathodic density (CCD) 0.9 A/cm2 and cryolite ratio (CR) 2.2. manganese content up to 3.0 wt%. Manganese added form Mn2O3. Bath sam...

objective:at the present study, relationship between phagocytosis of plga particles and combined effects of particle size and surface pegylation was investigated.  materials and methods:microspheres and nanospheres (3500 nm and 700 nm) were prepared from three types of plga polymers (non-pegylated and pegylation percents of 9% and 15%). these particles were prepared by solvent evaporation metho...

hypothesis may still lbe a topic for controversy among philosophers, but among the great majority of active scientists I think it is accepted without question The workings of our minds and bodles, and of all the animate or lnanimate matter of which we have any detailed knowledges are as sumed to be controlled by the same set o£ fundamental laws which except under certain extreme conditions we f...

For a model of weakly coupled quantum Ising chains we outline the phase diagram and establish that well below the transition line the system has a remarkably one-dimensional spectrum. We study the dynamical magnetic susceptibility and find a very rich spectrum with several modes corresponding to a fundamental particle and its bound states. The approach is based on the Bethe ansatz and the rando...

Precipitative mixing experiments have been conducted with the aid of a turbidimeter and a darkfield microscope. The results of these experiments, correlated with observations of macroscopic features, indicate that serological precipitation is largely governed by a highly specific mechanism except in the terminal period, when the operation of non-specific forces becomes apparent. The findings ar...
