Complementariteit in kennistheoretisch perspectief
… They are found in the work of different authors (Bohr, Whitehead, systems theory, Bohm, Löfgren, Prigogine). Bohr explicitly formulates a theory of complementarity, combining the two ways of description. How do other authors combine their two views of reality, is the concept of complementarity …

Exciton confinement in strain-engineered InAs quantum dots in metamorphic In_{x}Ga_{1-x}As
… increasing QD-CL mismatch (QD strain), while its Bohr radius has no correlation with mismatch. The diamagneticshift coefficient increases 12-fold with decreasing mismatch from ∼ 7.5 % to 4.5 %, which is attributed to low effective mass, which in turn, is due to low QD strain. For high mismatch (> …

Oxidation states of copper on the (001) magnesium oxide surface, and the adsorption of hydrogen, oxygen and carbon monoxide atop copper on the (001) magnesium oxide surface (an ab-initio cluster calculation in the Hartree-Fock approximation)
… of about 9 eV, and it stays stably at about 1 Bohr above the surface as a Cu++ ion: A Cu atom donates 2 electrons to empty antibonding surface orbitals of the surrounding surface oxygens. A Cu+ ion donates one electron to similar surface orbital. A Cu++ cannot stay stably in a Mg-vacancy.

Complementarity and the practice of psychotherapy : an alternative to eclecticism
… of complementarity as postulated by Niels Bohr in order to develop an alternative approach. This philosophy stresses the indeterminate nature of the object of study in psychology, and therefore holds that it is necessary to entertain multiple perspectives. It also holds that in order to …

Domains of convergence in infinite dimensional holomorphy
… methods from the theory of multidimensional Bohr radii. The problem of conditional convergence is solved for polynomials. It is closely connected with bases for full and symmetric tensor products and convergence preserving permutations.

Developmental changes in the structure and function of lobster hemocyanin
… other larval stages and that of the adult. The Bohr shift showed a significant increase at stage III, but no additional significant changes occurred in the slope prior to or subsequent to that stage. Cooperativity showed no trend with pH at any stage, except possibly in stage I. SDS-PAGE gels of …

Peculiarities of crystal and magnetic structures of synthetic Co-olivine, Co 2 SiO 4
… diffraction data were found to be 3.86(5) Bohr magneton and 3.37(4) Bohr magneton for Co1 and Co2, respectively. These values are much higher than the spin-only one for high-spin Co2+ (3 Bohr magneton) indicating the orbital contribution. This is in agreement with both magnetic …

Transformations of photography in Japan (1990-1999)
This dissertation examines photography in Japan via the new generation of young female photographers who emerged during the social, economic and political shifts of the post-bubble era (1990–1999). This new generation of photographers initiated a paradigmatic shift in photographic discourses within …

Expression und Funktion von Brain-derived-neurotrophic-factor in humanen Podozyten
Der derzeitige Kenntnisstand betreffend des neuronalen Wachstumsfaktors BDNF beruht überwiegend auf neurobiologischen Untersuchungen. Daher bleibt die mögliche Bedeutung einer in jüngster Zeit beobachteten BDNF-Expression auch in nicht-neuronalen Geweben zukünftig weiter abzuklären. <br> <br>In …

Stability, Range and Statistical Aspects of non-Abelian X-ray tomography
The non-Abelian X-ray transform on a Riemannian manifold with boundary (M,g) is a nonlinear map A → CA that associates to a matrix-valued and possibly direction-dependent function A, referred to as attenuation, its scattering data CA. The scattering data records initial-to-end-value maps for the …

The social bases of climate skepticism: Risk perception, ideology, and the creation of carbon publics
This dissertation examines the politics of expertise in the United States through the case of climate skepticism. Growing consensus on the reality and drivers of global climate change within the scientific community coincides with an intense political polarization over climate change beliefs and …
