2. 1. Quantum many-body systems exactly solved by special functions

   Author : Martin Hallnäs; Edwin Langmann; Pavel Winternitz; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum many-body systems; integrable systems; special functions; Mathematical physics; Matematisk fysik;

   Abstract : This thesis concerns two types of quantum many-body systems in one dimension exactly solved by special functions: firstly, systems with interactions localised at points and solved by the (coordinate) Bethe ansatz; secondly, systems of Calogero-Sutherland type, as well as certain recently introduced deformations thereof, with eigenfunctions given by natural many-variable generalisations of classical (orthogonal) polynomials. The thesis is divided into two parts. READ MORE

4. 2. Modulation of Neuronal Functions : the Role of SLC10A4

   Author : Kalicharan Patra; Klas Kullander; Håkan Aldskogius; Per Svenningsson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dopamine; acetylcholine; central nervous system; neuromuscular junctions; electrophysiology; monoamine; synaptic transmission; neuromodulation; Neuroscience; Neurovetenskap;

   Abstract : Mental health of a person depends on the correct functioning of the brain. The brain and the spinal cord contain many types of cells, of which one important type are called the neurons. Neurons are special in the way they connect to each other to form large networks. READ MORE

5. 3. The market for whom? Consumers in need of special support in the Swedish market system of education

   Author : Jude K. Tah; Rune Hausstätter; Helen Knutes-Nyqvist; Christopher Lubienski; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Education market; consumers in need of special support; special education market; school marketing; shopping for schools; specialpedagogik; Special Education;

   Abstract : The aim of this thesis was to analyse and describe the market system of education for consumers in need of special support. Sweden in the beginning of the 1990s implemented a market system of education with the expectation that it will serve the interest of all consumers. READ MORE

6. 4. Limit Theorems for Lattices and L-functions

   Author : Kristian Holm; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lattices; L-functions;

   Abstract : This PhD thesis investigates distributional questions related to three types of objects: Unimodular lattices, symplectic lattices, and Hecke L-functions of imaginary quadratic number fields of class number 1. In Paper I, we follow Södergren and examine the asymptotic joint distribution of a collection of random variables arising as geometric attributes of the N = N(n) shortest non-zero lattice vectors (up to sign) in a random unimodular lattice in n-dimensional Euclidean space, as the dimension n tends to infinity: Normalizations of the lengths of these vectors, and normalizations of the angles between them.

7. 5. Assessing Soil Functions for Sustainable Remediation of Contaminated Sites

   Author : Yevheniya Volchko; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; soil ecosystem services; Contaminated sites soil; minimum data set; remediation; sustainability assessment; soil quality indicators; soil functions;

   Abstract : Soil contamination is a worldwide problem. Soil remediation is often carried out to reduce the risks posed by contaminants in the soil to human health and environment. Contaminant concentration is typically the only soil quality aspect maintained in remediation projects. READ MORE
