2. 1. Aspects on Image Quality in Radiologic Evaluation of the Urinary Tract

   Author : Margareta Lundin; Anders Persson; Torbjörn Andersson; Håkan Geijer; Anders Magnuson; Jan Persliden; Anders Magnusson; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : The focus of this document is on image quality as one of the factors fundamental for the diagnostic process. With the rising number of procedures and the trend towards more complicated examinations, urinary tract investigations was chosen in this work as a good clinical model for evaluation of the factors influencing image quality and of the ways of evaluating image quality.

4. 2. Opioids regulate proliferation of neural progenitors. A study on the effects of opioids on adult rat hippocampal progenitors in vitro and in vivo

   Author : Anders I. Persson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Opioid; brain; hippocampus; rat; neurogenesis; progenitor; stem cell; b-endorphin; calcium; MAPK;

   Abstract : The opioid receptors were among the first pharmacologically described brain receptors. These opioid receptors have thereafter been shown to mediate effects on proliferation and differentiation in both the embryonal and adult central nervous system. READ MORE

5. 3. Evaluation of a Miniaturized Rotating Disk Apparatus for In Vitro Dissolution Rate Measurements in Aqueous Media : Correlation of In Vitro Dissolution Rate with Apparent Solubility

   Author : Anita M. Persson; Curt Pettersson; Anders Sokolowski; Anders Karlsson; Alex Avdeef; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; analytical methods; HPLC high-performance liquid chromatography ; miniaturization; in vitro dissolution rate; apparent solubility; physicochemical properties; dissolution media; correlation study; chemometrics; Pharmaceutical chemistry; Farmaceutisk kemi; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

   Abstract : The general aim of this thesis was to evaluate a newly designed and constructed miniaturized rotating disk apparatus for in vitro dissolution rate measurements of different drug substances from all of the classes in the Biopharmaceutical Classification System (BCS). The new equipment is based on a low volume flow-through cell of Plexiglas, a gold plated magnetic bar and a special designed press. READ MORE

6. 4. Defining, Securing and Building a Just Peace : The EU and the Israeli-Palestinian conflict

   Author : Anders Persson; Statsvetenskapliga institutionen; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Isareli-Palestinian conflict; peace; EU; peace building; Just peace; Middle East peace process; Legitimizing power Europe;

   Abstract : Just peace has been much talked about in everyday life, but it is less well researched by academics. The puzzle underlying this dissertation is therefore to probe what constitutes a just peace, both conceptually within the field of peacebuilding and empirically in the context of the EU as a peacebuilder in the Israeli-Palestinian conflict.

7. 5. Diversity and Interference Aspects in the Downlink of Code Division Multiple Access Systems

   Author : Anders Persson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; orthogonal frequency division multiplexing; multi-carrier modulation; Rayleigh-fading channels; code division multiple access; frequency-selective channels; multiple access interference; diversity;

   Abstract : This thesis consists of six included papers and technical reports, plus an introduction. The topic studied is interference and diversity aspects in code division multiple access (CDMA) systems for mobile cellular communications. The focus in the papers is on the downlink - the communication link from the base station to the mobile terminal. READ MORE
