[Juel-2001]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 2001, 230 p. (1985)
The subject of this thesis has been to study the interaction of a metallic cobalt catalyst with zeolite supports and alkali as promoter in the CO hydrogenation reaction. For this purpose molecular sieves of the types of zeolite 4A, chabazite/erionite, ZSM-5, silicalite, mordenite and zeolite $\gamma$ as well as two silica carriers have been impregnated with aqueous cobalt-nitrate solution and reduced. [...]

Untersuchung der Dynamik von sauberen Ni(100)-Oberflächen und darauf adsorbierten (2x2)-Strukturen von C, O und S
[Juel-2000]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 2000, 118 p. (1985)
Phonon dispersion was studied by EELS in the impact scattering regime along high symmetry directions $\overline{r} \overline{M}$ of the two dimensional Brillouin zone of Ni(100). The measurements were performed for the clean surface as well as for (2x2) phases of carbon, oxygen and sulfur adsorbed on it. [...]

Wachstum und Zusammenwirken von Scenedesmus falcatus und Pseudomonas bei chemostatischer Kultur in acetathaltigem Modellabwasser
[Juel-1999]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 1999, 166 p. (1985)
Die aerobe Behandlung von Abwässern in unbelüfteten flachen Teichen beruht, analog zur natürlichen Selbstreinigung der Oberflächengewässer, hauptsächlich auf dem Zusammenwirken von Algen und Bakterien. Dabei ist die photosynthetische O$_{2}$-Produktion der Algen von entscheidender Bedeutung für die Aufrechterhaltung eines aeroben Stoffwechsels der Bakterien (Arthur 1982). [...]

Neutronenstreuung an zwischenvalenten Systemen
[Juel-1998]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 1998, III, 155 p. (1985)
The temperature dependence of the magnetic relaxation line widths (quasielastic (QE) line widths) and the crystal field excitations of some novel intermediate valent systems were measured by means of inelastic neutron scattering. Some striking new features of the alloys YbBe$_{13'}$ YbPd and Yb$_{3}$Pd$_{4}$ appoint them to belong to a new type of intermediate valent systems. [...]

Enhanced neoclassical pinch in the collisional regime of tokamaks
[Juel-1997]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 1997, 23 p. (1985)
It is shown that the parallel electron viscosity leads to an enhanced pinching effect in the collisional regime. The inward neoclassical convection velocity is < U$_{r}$ > = - < cB$_{X}E_{\varnothing}/B^{2}$ > [1 + 2.15 q$^{2}$ ($\lambda_{mfp} / qR)^{2}$]- assuming cylindrical cross-sections - where $\lambda_{mfP}$ is the electron mean-free path.

Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 1994, II, 113 p. (1985)
Presently, the highest performance computer systems are the vector processors which are mainly employed for technical and scientific applications. However, the performance potential of the pipelined functional units of a vector processor can only efficiently be used if the required data transfer between main memory and the CPU, respectively the CPUs in case of multiprocessor systems, can optimally be routed.

Stochastic field line structures appearing in field line tracing calculations for a helical magnetic limiter on TORE SUPRA
[Juel-1993]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 1993, [1], 12, [26] p. (1985)
The influence an the structure of the magnetic field of a tokamak produced by small helical currents flowing near the plasma in TORE SUPRA was investigated numerically by drawing Poincaré plots. The current in the helical conductors, the pitch of the windings, the rotational Irans form and the plasma pressure ha gre been varied. [...]
