In the construction industry, sustainability and greening is more than just a passing trend. It has become an important agenda since the building sector has immense environmental impacts. It accounts for 42% of final energy consumption and about 35% of all greenhouse gas emissions. In order to meet these challenges, the construction industry needs to change and adopt new working procedures which t
This report contains a summary of the work with spherical electrical machines found in the specialised literature. Spherical actuators allow several degrees of freedom (DOF), which is particularly interesting in robotics. Complex movements are traditionally accomplished by combining several electrical machines with 1-DOF, ending up with an overweight actuator and accuracy problems due to tolerance
This paper presents a characterization method for millimeter wave (mmWave) phased array antennas in the mobile terminal for 5G communication. Arrays of different antenna designs, operating at 28 GHz, are evaluated according to novel characterization methods in this context - the total scan pattern of the phased array and its respective coverage efficiency. The results show the relevance of evaluat
The main objective of this thesis was to identify methods for the detection of ß-lactam resistance in staphylococci, bacteria often causing nosocomial infections. Detection of ß-lactam resistance in these species is difficult due to strong regulation of genes encoding for the two main resistance mechanisms, ß-lactamase production and the penicillin-binding protein (PBP) 2?. ß-lactamase has high af
The aims of this study were: to compare the cartilaginous outline of the femoral head obtained on arthrograms with those on MR images and to correlate it to the bony head outlines on conventional radiograps; to study early, postoperative cartilaginous and bony remodeling of the femoral head, after proximal femoral varus derotation extension osteotomy, with MR imaging and conventional radiography;
The ECL cells in the stomach produce, store and secrete a variety of secretory products, such as histamine and chromogranin A-derived peptides (e.g. pancreastatin). The functional significance of the ECL cells can be expected to reflect the nature/bioactivity of the secreted products. Although the anticipated peptide hormone of the ECL cells remains unidentified, ECL-cell histamine is recognized a
In this paper we analyze how the spatiality of interactions influences trust creation in multi-site corporate innovation projects. By drawing on insights from the discussion on initial and gradual trust and connecting them to contributions from the field of economic geography, we examine different antecedents of trust and their dependence on face-to-face interaction. We thereby illustrate the comp
The equilibrium self-assembly of cationic surfactants in bulk solution and at negatively-charged silica substrates is investigated experimentally and theoretically. The surfactants used are quaternary ammonium salts, both monovalent (DoTAB, TTAB, CTAB) and divalent (DoPPDAC). The adsorption of DoPPDAC to silica, in the absence or presence of added electrolyte, is studied with the technique of null
This thesis is about how and in opposition to what punk is defined and lived out by punks in Sweden and Indonesia. Arguing against the previous research’s presumption that subcultural meaning constitutes a single set of meaning, this study points to two patterned sets of meanings, each constructed out of several different definitions of the mainstream as well as the subcultural authentic.
