A strong molecule-surface interaction between free-base-tetra(4-bromophenyl)-porphyrin and Cu(111) results in a distortion of both the molecule and the underlying copper surface in the vicinity of the molecule. This in turn leads to the formation of an intermediate complex due to bonding between the iminic nitrogens and surface copper atoms.

Almost all cortical areas are connected to the subcortical basal ganglia (BG) through parallel recurrent inhibitory and excitatory loops, exerting volitional control over automatic behavior. As this model is largely based on non-human primate research, we used high resolution functional MRI and diffusion tensor imaging (DTI) to investigate the functional and structural organization of the human...

In the investigation of the symptom, dyspnea, by physiological methods studies of the pulmonary mechanisms have lagged behind those of other mechanisnis involved. In most clinics the measurement of the vital capacity is frequently made, but rarely in conjunction with measurements of total pulmonary air and its subdivisions. No complete understanding of the problem can be attained without a comp...

When several decades ago the IRB system was established trying to balance major moral consideration in research with human subjects, the main impetus were severe cases of unethical behaviour and experiences, often protected by state and institutional administration. The first phase of the IRB aimed at protecting subjects from serious hazards, while in later stages the IRB turned to „lesser risk...
