The steps involved in the grafting of mesencephalic and septal embryonic tissue in the form of dissociated cell suspensions are described in detail. This includes dissection of the donor embryos, incubation in trypsin, mechanical dissociation, and stereotaxic injection into the brains of adult recipient rats. Some of the technical problems and limitations are discussed.
This thesis confronts a fundamental shortcoming in cognitive science research: a failure to be explicit about the theory of concepts underlying cognitive science research and a resulting failure to justify that theory philosophically or otherwise. It demonstrates how most contemporary debates over theories of concepts divide over whether concepts are best understood as (mental) representations or
Collaboration involving student–industry activities entails a complex interaction between university, students, and industry. The university–student–industry triangle identified here is neither static nor balanced, and each of the three intertwined relationships displays distinguishing characteristics. Each has its own structure; the activity phases of the relationships are not synchronous, and ea
We address the impact of a too short cyclic prefix on multicarrier systems such as orthogonal frequency division multiplexing (OFDM) and discrete multitone (DMT). The main result is that the intersymbol interference (ISI) and intercarrier interference (ICI) may be spectrally concentrated and analytical expressions showing this are given. A practical implication is, e.g., that the cyclic prefix in
The aim of the study was to investigate the role of clinical experience in the acquisition of professional competence during education and training in nursing. Competence is given a relational interpretation. The acquisition of professional competence is considered in terms both of the subject area involved and of cultural and organizational aspects specific to the nursing profession and to nursin
We illustrate the potential of Time Dependent Density Functional Theory (TDDFT) for describing the nonequilibrium behavior of strongly correlated (lattice) models. Starting from an exact time-evolution of the many-body wavefunction, we determine, via reverse engineering, the exact exchange correlation (xc) potential $v_{xc}$ for small Hubbard chains of different lengths and electron fillings and e
The frame story
takes place in a dystopian Europe, possibly some kind of European Union around 2050 – in a state of conflicts and decay. The protagonists are a retired general, Piscator (cf. Fisher King) and a former journalist, Perle Vaus (cf. Perlesvaus/Perceval/Parsifal). She lost her home because of a new genderrelated law and stays homeless with others, covered by the Saxon bridge.
A humanoid dummy inside a well controlled radon exposure chamber (volume=20m3) was used to investigate the properties of an aerosol close to, and far away from the human face, respectively. Rn222 and a NaCl aerosol (geometric mean diameter=86 nm, concentration ( 5000 cm-3 was added to the room. The size distribution of the passive aerosol and the unattached fraction of the radon progeny were measu
The study of spin transport has emerged at the forefront of condensed matter physics during the last decade. Much of the interest has undoubtedly been sparked by the advent of the spintronics paradigm and the idea of creating novel electronic devices based on the spin degree of freedom of the carriers. However, a great deal of interest is due to the rich physics that emerges from the study of spin
Geophysics measurement techniques can be considered as non-destructive, remote methods to analyse the physical properties of geologic materials hidden at depth in the earth, within geotechnical structures or within laboratory test specimens. The objective of this paper is to highlight at least some of the potential to use geophysics methods to aid geomechanical investigations, both at the laborato
