In the recently introduced high-contrast transmission version of saturated absorption laser spectroscopy, narrow signals are obtained from dense atomic samples subject to strong pumping. A study of possible systematic shifts of the signals in this domain of rather extreme experimental conditions was performed in order to assess the validity of spectroscopic data obtained with this technique. Certa

Purpose. To investigate how individualised occupation-based interventions with commonly available everyday technology (ET) can compensate for perceived difficulties with daily life tasks after an aquired brain injury (ABI) and improve satisfaction with occupational performance. Method. This intervention study was designed as a multiple case study according to Yin. Ten men and women with an ABI (tr

Experimental studies have established that the sulfated glycosaminoglycans heparan sulfate and chondroitin sulfate act as co-receptors of cytokines and growth factors that drive the malignant cell phenotype and the remodelling of the surrounding tumor stroma. However, the clinical relevance of these studies remains ill-defined. The present study investigates the significance of chondroitin sulfate

The article studies the character of general readers’ reviews on the internet bookstore Amazon; what is called private criticism. Patterns, common features, and contradictions are explored, and the social position and meaning of new forms of readers’ expressions is discussed. One part of the thesis is that the freedom of speech in the public sphere has given readers new and different opportunities

Cardiac troponins are biomarkers of myocardial injury and serve both diagnostic and prognostic purposes. Even mild elevations represent subclinical myocardial damage in the general population. The objective of this study was to investigate the relationship between glucometabolic status and cardiac troponin T in middle-aged or older apparently healthy subjects.

I argue that the human sciences (i.e. humanities, social- and behavioural sciences) should not try to imitate the methodology of the natural sciences. The human sciences study meaningful phenomena whose nature is decisively different from the merely physical phenomena studied by the natural sciences, and whose study therefore require different methods; meaningful phenomena do not obviously obey na

The amplified spontaneous emission spectra of quantum-cascade laser structures is computed with a Keldysh Green's functions theory. We show that the emission spectra are sharpened in comparison to gain spectra due to wave guide propagation. In addition the different dependence on level occupation causes moderate differences between gain and emission peak positions. Our fit-parameter-free theory is

Non-therapeutic research on children raises ethical concerns. Such research is not only conducted on individuals who are incapable of providing informed consent. It also typically involves some degree of risk or discomfort, without prospects of medically benefiting the participating children. Therefore, these children seem to be instrumentalized. Some ethicists, however, have tried to sidestep thi
