This thesis studies the relationship of cultural and economic segregation with politics. Based on a theoretical model where the provision of a public good depends on how far apart voters are in terms of preferences, it is suggested that the support for the Sweden Democrats (Sverigedemokraterna) to some extent is driven by segregation. Using municipal level data on incomes and namesday names in ...

In this paper we investigate the properties of a one-dimensional quantum wire of interacting electrons in the Wigner crystal limit. Recent theoretical work has explored some of the classical and quantum phase transitions associated with this system. For example, there exists a critical density above which the system can lower its energy by forming a quasi-one-dimensional zig-zag chain. We also ...

The validity of the Bianchi identity, which is intimately connected with the zig zag symmetry, is established, for piecewise continuous contours, in the context of Polakov’s gauge field-string connection in the large ’tHooft coupling limit, according to which the chromoelectric ‘string’ propagates in five dimensions with its ends attached on a Wilson loop in four dimensions. An explicit check i...

Abstract The generation of the printing paths is a decisive step in additive manufacturing (AM). There variety patterns that offer different characteristics, but those are strictly continuous become especially relevant certain types AM by extrusion, with materials like bioinks, carbon or clays, since they do not allow retraction material and travelling movements result artifacts. In this work, ...

Introduction: Obesity and visceral fat accumulation after menopause are associated with insulin resistance and cardiovascular diseases. We investigated the interactive effect of aerobic-resistance training and estrogen replacement therapy on visceral fat, omentin-1 and HOMA-IR in ovariectomized rats. Materials and Methods: Fifty female Wistar rats were ovariectomized (OVX) and divided into 5 gr...

We investigate self-moving particles which prefer to hop with a certain turning angle equally distributed to the right or left. We assume this turning angle distribution to be given by a double Gaussian distribution. Based on the model of Active Brownian particles and we calculate the diffusion coefficient in dependence on the mean and the dispersion of the turning angles. It is shown that boun...
