1/Nc1/N_c Rotational Corrections to gAg_A in the NJL Model and Charge Conjugation

We show that the $1/N_c$ rotational corrections to $g_A$, derived using the semiclassical quantization scheme in the NJL model, possess correct properties under charge conjugation.Comment: 4 pages, revtex, no figures, final version published in Phys.Rev.C52(1995)42

On reductions of soliton solutions of multi-component NLS models and spinor Bose-Einstein condensates

We consider a class of multicomponent nonlinear Schrodinger equations (MNLS) related to the symmetric BD.I-type symmetric spaces. As important particular case of these MNLS we obtain the Kulish-Sklyanin model. Some new reductions and their effects on the soliton solutions are obtained by proper modifying the Zakahrov-Shabat dressing method.Comment: AIP AMiTaNS'09 Proceedings

RECURRENCES OF ТYPHUS FEVER

During recent years in our country а sharp decrease is observed in the incidence rаtе of typhus fever, typhoid fever, malaria, diphtheria, anthrax,  etc. We аге now about to eradicate typhus fever as an infectious disease in our countгy. Thanks to the incessant and rapid improvement of the economic and cultural standard of our people and the continuous improvement of the medical services, there exists the actual possibility to eradicate this disease in the next few years.For these reasons for the present there are а number of particularities in the epidemiology and the clinical picture of typhus fever: sporadic nature of the disease; lack of louse infestation in the focus of infection and in the patient; difficulties in the detection of the source of infection; lack of seasonal determination; а milder clinical course of the disease and very low mortality гates; involvement almost exclusively of adults; difficulties in detection of Rickettsia  Prowazeki in the patient's blооd

Weak electricity of the Nucleon in the Chiral Quark-Soliton Model

The induced pseudotensor constant (weak electricity) of the nucleon is calculated in the framework of the chiral quark soliton model. This quantity originates from the G-parity violation and hence is proportional to $m_u-m_d$. We obtain for $m_u-m_d=-5 MeV$ a value of $g_T/g_A =-0.0038$.Comment: The final version.
