Copper and nickel ions are accumulated in the solution during electrolytic refining of copper. These ions need to be extracted from the solution from time to time. In industry copper extraction is carried out in two stages. It results in copper ions

The precision of approximate Kramers formulas for the nuclear-fission rate in the presence of shell corrections in a quasistationary state is studied. The rates in question obtained analytically are compared with their numerical counterparts resultin

The precision of the Kramers formulas, which are frequently used to calculate the rate of fission of excited nuclei, is studied quantitatively bymeans of a numerical simulation. The deformation dependence of the level-density parameter is taken here

Two recipes for modeling the dynamics of the nuclear fission process are known in literature. The underlying equations contain the driving, dissipative, and random forces. The two recipes are mostly different in the prescriptions for the driving forc

Patients with multiple sclerosis were found to have increased cerebrospinal fluid, noradrenaline, and excitatory amino acid (glutamate and aspartate) levels, with increased blood glutamine, asparagine, and glycine levels. An association was found bet

Neurotransmitters and cytokines that play a key role in the mechanisms of interaction of the nervous and immune systems have been studied in both the blood and cerebrospinal fluid of 195 patients with multiple sclerosis. The findings suggest that neu

Elevated levels of norepinephrine and of excitatory amino acids (glutamate, aspartate) were observed in cerebrospinal fluid of patients with multiple sclerosis while there were elevated content of glutamine, asparagine and glycine in their blood. An
