The validity is in this volume grounded in a shared perception of research on human action, its conditions and consequences, as a human science rather than “social” or “behavioral” science. Validity is here more than the validity of representations, as research is not a mirror held to nature. The function of research is rather to clear the ground for change. All of the authors have done research c

Communication systems using multicarrier modulation suffer from a high peak-to-peak ratio, PAR. In this work we use the tone reservation approach to PAR reduction, where a subset of the tones are used for PAR reduction. We derive a bound on the achievable performance under a PSD constraint on the transmit signal. Using this bound, we show that as long as a moderate reduction performance is needed,
Popular Abstract in Swedish Kalcium är ett livsviktigt ämne för både djur och växter. Kalcium behövs t.ex. för uppbyggnaden av skelettet, för att hjärtat skall slå och för att musklerna skall dras samman. I växter är kalcium en viktig beståndsdel i cellväggarna och behövs också vid bl.a. celldelning. Trots detta måste koncentrationen av fria kalciumjoner inne i cellen (i cellvätskan) hållas mycketThe calcium ion (Ca2+) is essential for all plant and animal life. One important function of Ca2+ is as a second messenger in the responses of the cell to environmental and hormonal signals as well as in some intrinsic developmental processes. The intracellular concentration of Ca2+ must be strictly regulated, since a high concentration of free cytosolic Ca2+ is toxic. All eukaryotic cells carry c
Methodological tools for studies of the cytostatic agen cisplatin (CDDP) were explored and applied to elucidate various aspects of pharmacokinetics, drug distribution, chemomodulation and pharmacodynamics. An immunohistochemical assay for analysis of CDDP-DNA adducts, i.e. the drug in its probable target position, was modified to allow quantitation with computerized image analysis. The methodologi
