It is not your fault – family counsellors work with sexually abused children and youth. Sexual abuse is a global phenomenon, occurring at every level of society. Previous studies show that victims often tell their stories about sexual abuse in a counselling setting. Family counsellors were chosen as respondents due to the fact that they work with different types of treatment and counselling and t

We propose a description of nonequilibrium systems via a simple protocol that combines exchange-correlation potentials from density functional theory with self-energies of many-body perturbation theory. The approach, aimed to avoid double counting of interactions, is tested against exact results in Hubbard-type systems, with respect to interaction strength, perturbation speed and inhomogeneity, an

A real photon has a dual nature, as a pointlike elementary particle and as a qq fluctuation, in the latter case often with hadron-like properties. Therefore high-energy γp interactions have a rich and not yet well explored structure. In this paper, we propose a consistent formulation, which is based on a subdivision of the total cross section into three distinct event classes: direct, VMD and anom

A detailed analysis of the classic Stern-Gerlach experiment is presented. An analytical simple solution is presented for the quantum description of the translational and spin dynamics of a silver atom in a magnetic field with a gradient along a single z-direction. This description is then used to obtain an approximate quantum description of the more realistic case with a magnetic field gradient al

A description of texture evolution at large strain plasticity is developed. Texture evolution is defined in terms of changes taking place in the substructure of the material. The changes in the substructure are specified by means of a tangent map defined in the same manner as for the continuum in terms of a multiplicative decomposition. It is shown that the description of the changes in the substr

High-order Harmonic Generation (HHG) is a highly non-linear process in which an atom interacts with a strong laser field. The laser field lowers the atomic potential barrier allowing bound electrons to escape into the continuum through tunnel ionization, propagate, and, with some probability, recombine with the parent ion. As a result, coherent eXtreme UltraViolet (XUV) radiation is emitted in the

In the age of miniaturization where the physical systems approach the nanoscale limit andwhere more complex materials are created there is necessity for understanding in terms ofquantum mechanics. The understanding then opens and gives possibilities for manipulationand engineering of such systems and thus practical applications.Quantum mechanics states that the electron cannot be characterized as In this thesis we focus on improvements of the description of the electron-electron correlation effects in nonequilibrium nanosystems. We mainly focus on developments of two nonequilibrium methods, namely the formalism of Nonequilibrium Green’s Function and Time Dependent Density Functional Theory and we explore the possibility to improve existing approximations in these theories. A smaller part o

Parasol is a computer program for calculating the solar and thermal properties of windows with sunshades and the energy demands of a room with a window/shading system. The program has three main features. One of them is a calculation of g, T and U for normal incidence of beam irradiation, which is performed as soon as a window or an internal/interpane sunshade is selected. The other two are based

The high-spin parts of shears bands observed in Pb-198,Pb-199 are described by coupling several valence particles to a deformed rotor core. To give the model enough freedom so that both the proton and the neutron spin vectors can find their preferred direction, the use of five to six valence particles and holes is found to be necessary. Effective parameters characterizing the rotor are deduced fro

The neutral Kaon system has both CP violation in the mass matrix and a non-vanishing lifetime difference in the width matrix. This leads to an effective Hamiltonian which is not a normal operator, with incompatible (non-commuting) masses and widths. In the Weisskopf–Wigner Approach (WWA), by diagonalizing the entire Hamiltonian, the unphysical non-orthogonal “stationary” states KL,S are obtained.

The modeling of multiple parton interactions in Monte Carlo event generators is a crucial part not only for the dressing of signal processes but also to describe data with a minimum bias on the event selection. Much work has and will be put into the theoretical framework and the numerical implementation of these models. In this contribution, we document various improvements of the multiple parton

Queer theology is relative new in the Academy of Theology, especially in the Swedish context. It derives from both liberation and feminist theology. Furthermore queer theology can also be understood as an extension of queer theory. Gerard Loughlin has intentionally incorporated elements from queer theory in his theological work. The purpose of the thesis is to analyze the texts of St. Augustine an

The structure of β-Mn crystallizes in space group P4 132. The pseudo 8-fold nature of the 4 1 axes makes it constitute an approximant to the octagonal quasicrystals. In this paper we analyze why a five-dimensional super space group containing mutually perpendicular 8-fold axes cannot generate P4 132 on projection to 3-d space and how this may instead be accomplished from a six-dimensional model. A

En el presente trabajo se presenta una investigación sobre las dificultades a las que se enfrentan estudiantes suecos de español como lengua extranjera (desde ahora ELE), a la hora de elegir entre los tiempos del pasado imperfecto e indefinido en relación con verbos de estado y de logro. El propósito de este estudio es describir, de manera general, la producción de errores para visualizar en qué m
