Displacement correlation of classical ions in the incommensurate Fröhlich model of a one- dimensional metal
[Juel-1337]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 1337, 60 p. (1976)
The one-dimensional Fröhlich model is investigated for k$_{B}$T $\ll$$\delta_{o}$ $\ll$E$_{F}$ with $\delta_{o}$ the mean field Peierls gap at T = O. Treating the ions classically and neglceting bandstructure and Umklapp effects the electronic energy for a given ion distortion is determined by Bogolyubov-type equations with a $\underline{complex}$ order parameter.

Conductance change of the arthropod visual cell membrane in response to light, indirectly depending on membrane potential
[Juel-1331]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 1331, 84 p. (1976)
In retinular cells of Astacus and Limulus the following electrical characteristics of the visual cell membrane were measured by a single intracellular microelectrode: (1) the pre-stimulus membrane potential, pMP; (2) the light-induced receptor potential, ReP; (3) the input resistance of the measuring circuit in the dark; Rd, which is the sum of the resistances of cell membrane, visual cell and recording electrode; and (4) its light-induced change $\Delta$R, which can be attributed mainly to a change in membrane resistance. Results: 1) During the light response both membrane resistance and membrane potential change with a similar but not identical time course. [...]

Untersuchung von Blochwänden und Domänen in Bariumferrit mit magnetischer Kernspinresonanz
[Juel-1330]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 1330, 55 p. (1976)
Das Ziel dieser Arbeit ist es, zu untersuchen, welche Information über die Struktur und Bewegung einer Blochwand aus der Kernspin-Resonanz zu gewinnen ist. Die beste Information kann man erhalten, wenn die Resonanzfrequenz anisotrop ist, so daß eine getrennte Messung der verschiedenen Magnetisierungsrichtungen in der Wand möglich ist. [...]

Untersuchungen zum Bau eines hochauflösenden Magnetspektrometers und Modellmessungen zur Wirkungsweise von Feldkorrekturströmen in Eisen
[Juel-1329]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 1329, 111 p. (1976)
The experimental and theoretical influence of field correction currents in iron magnets (Ht-windings) is described. An estimate of electrical and mechanical tolerances of a high resolution magnet spectrometer is given. [...]

Konzeption für eine praxisnahe Berechnung der Ablagerung radioaktiver Stoffe aus der Abluft kerntechnischer Anlagen durch Niederschlag
[Juel-1328]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 1328, 14 p. (1976)
In connection with a realistic calculation of soil contamination caused by the washout of radioactive nuclides from the waste air of nuclear installations, there arises the question of how to proceed, if, in view of the very time-consuming efforts required for the preparation of sufficiently secured statistics, dispersion-climatological data are available to a limited extent only, such as are required e.g. for safety reports for nuclear power stations.

Experiences with a matrix bandwidth reduction method applied to a finite element problem
[Juel-1326]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 1326, 22 p. (1976)
Large sparsely populated matrices of diagonal character are common in finite element calculations. Computer time is saved and exactness improved if the matrix bandwidth is small. [...]

Verbesserung der leitprobenfreien Analyse in der Funken-Massenspektrometrie durch vollständige Nutzung der Fotoplatteninformation
[Juel-1325]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 1325, 82 p. (1976)
With an autanatic photoplate-evaluation systan in Spark-Source Mass Spectrometry, complete photoplate information is used for the concentration-procedure, that means, all isotopes of single and multiple-charged ions contribute to the analytical result. Experiments show that the ion-intensities of elements in their ionisation states lie on parabolas. [...]

Dissipation in a superconducting artificial atom due to a single nonequilibrium quasiparticle
ddc:530
We study a superconducting artificial atom which is represented by a single Josephson junction or a Josephson junction chain, capacitively coupled to a coherently driven transmission line, and which contains exactly one residual quasiparticle (or less than one quasiparticle per island in a chain). We study the dissipation in the atom induced by the quasiparticle tunneling, taking into account the quasiparticle heating by the drive. [...]

Aspergillus fumigatus Infection-Induced Neutrophil Recruitment and Location in the Conducting Airway of Immunocompetent, Neutropenic, and Immunosuppressed Mice
Journal of Immunology Research 2018(ID 5379085), 1 - 12 (2018) [10.1155/2018/5379085]  GO
ddc:610
Susceptibility to fungal infection is commonly associated with impaired neutrophil responses. To study the mechanisms underlying this association, we investigated neutrophil recruitment to the conducting airway wall after Aspergillus fumigatus conidium inhalation in mouse models of drug-induced immunosuppression and antibody-mediated neutrophil depletion (neutropenia) by performing three-dimensional confocal laser-scanning microscopy of whole-mount primary bronchus specimens.
