Eighth order solenoids

Eighth order solenoids for producing honogeneous magnetic fields were computed. One such solenoid, designed to contain a polarized ³He target, was built and tested. Compared to usual Helmholtz-type coils of similar size and efficiency the new arrangement can secure a high degree of homogeneity over a volume 15–60 times larger.     

Surgical treatment of lymphadenopathy in children

Clinical observations of 1365 children with the lymph nodes affection were summarized. The diagnosis verification was conducted using the broad arsenal of general clinical and special methods of investigation. In complicated situations the histochemical and immunogenetic methods were applied for the diagnosis. The structure and dynamics of children's morbidity with lymphadenopathies (LAP) was studied up, the age, sexual and seasonal peculiarities were systematized, the analysis of primary localizations and clinico-morphological comparisons was conducted. The basic thesises of the standardized approach were elaborated on the ground of the diagnostical and tactical mistakes results analysis.
