  abstract  = {A concept for the analysis and optimal design of reinforced concrete structures is described. It is based on a nonlinear optimization algorithm and a finite element program for linear and nonlinear analysis of structures. With the aim of minimal cost design a two stage optimization using efficient gradient algorithm is developed. The optimization problems on global (structural) and local (crosssectional) level are formulated. A parallelization concept for solving the two stage optimization problem in minimal time is presented. Examples are included to illustrate the practical use and the effectively of the parallelization in the area of engineering design.},

In order to improve upon pot spinning devices of this kind, the spinning pot is connected to an electric drive mechanism (10), mounted in magnetic bearings and provided with a gastight housing. Said housing encompasses the spinning pot (7), is open in the area where there is an opening in the end side of the pot and is provided with a seal (19) to seal off the intermediate area (17) between the housing and spinning pot. The housing is also connected to a supply of light-gas via a feed line (18), thereby enabling a light-gas atmosphere to be maintained in the intermediate area."},

A ferromagnetic spin structure is observed with magnetic moments oriented perpendicular to the c-axis of the hexagonal nuclear structure. The magnetic saturation moment of iron is 2.2 μB at 4.2 K from neutron diffraction and 2.0 μB from magnetic measurements and decreases in a Brillouin-like manner on heating to TC=575 K. Above 450 K an increasing but reversible disorder of the nitrogen partial structure is observed.},
