   Sammanfattning : An integrated use of radio magnetotelluric (RMT) and controlled source tensor magnetotelluric (CSTMT) measurements, the so-called CSRMT method, has been employed in environmental and resource exploration studies. A number of case histories, including a groundwater investigation in glacial deposits, a study of fracture zones for geotechnical purposes and a mining exploration study of a copper deposit, are presented in this thesis in order to illustrate the usefulness and capability of the CSRMT method.

3. 27. Effects of acute metabolic interventions on hemodynamics, endothelial function and forearm glucose uptake

   Författare :Andreas Fugmann; Uppsala universitet; []
   Nyckelord :Medical sciences; Insulin; glucose; lipids; bloodflow; endothelium; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

   Sammanfattning : Hyperinsulinemia is known to augment endothelium-dependent.vasodilation (EDV). If physiological levels of insulin lead to peripheral, vasodilation and if this vasodilation is an independent determinant of skeletal muscle glucose uptake is however under debate. LÄS MER

4. 28. A new method q-calculus

   Författare :Thomas Ernst; Hari M. Srivastava; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; MATEMATIK; MATHEMATICS; MATEMATIK; matematik; Mathematics;

   Sammanfattning : In q-calculus we are looking for q-analogues of mathematical objects, which have the original object as limits when q tends to 1. q-Calculus has wide-ranging applications in analytic number theory and theoretical physics. The main topic of the thesis is the invention of the tilde operator and the renaissance of the q-addition. LÄS MER

5. 29. Multiconfigurational perturbation theory

   Författare :Kerstin Andersson; Karlstads universitet; []
   Nyckelord :Electron correlation; CASSCF; multiconfigurational second-order perturbation theory; CASPT2; ozone; C; N; O; F; Si; P; S; Cl; Ni; benzene; pyridine; pyrazine; pyrimidine; pyridazine; s-triazine; electric properties; excited states; spectroscopic data;

   Sammanfattning : The aim of the thesis is to analyze a method which describes the electron correlation in atoms and molecules. The method is based on Rayleigh-Schrödinger perturbation theory with a partitioning of the Hamiltonian into a fairly simple zeroth-order operator and a perturbation operator. LÄS MER

7. 30. Foundation of Density Functionals in the Presence of Magnetic Field

   Författare :Andre Laestadius; Michael Benedicks; Trygve Helgaker; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Current density functional theory; Hohenberg-Kohn theorems; paramagnetic current density functionals; Kohn-Sham theory; Levy-Lieb functional; variational principle; N-representable; degeneracy; Mathematics; Matematik;

   Sammanfattning : This thesis contains four articles related to mathematical aspects of Density Functional Theory.In Paper A, the theoretical justification of density methods formulated with current densities is addressed. It is shown that the set of ground-states is determined by the ensemble-representable particle and paramagnetic current density. LÄS MER
