Functional convergence of dopaminergic and cholinergic input is critical for hippocampus-dependent working memory.
Although Parkinson's disease is a movement disorder, in many patients cognitive dysfunction is an important clinical sign. It is not yet clear whether this is attributable solely to a decrease in dopamine levels, or whether other neurotransmitter systems might be involved as well. In the present study, the importance of the mesocorticolimbic dopamine pathway and a possible convergence with forebra
Multiphysics modelling of PEM fuel cells - with reacting transport phenomena at micro and macroscales
Popular Abstract in Swedish Polymermembranbränsleceller (PEM) anses vara en mycket lovande teknik inom fordonsindustrin på grund av dess kompakthet i storlek, höga verkningsgrader samt låga arbetstryck och temperaturer. De senaste åren har tekniken varit fokus för en anseenlig mängd forskning. PEM-bränsleceller har den stora fördelen att energiomvandlingseffektiviteten har potential för att vara bThis thesis presents numerical simulations of reacting transport phenomena in polymer electrolyte membrane (PEM) fuel cells. Broadly, the presented work is subdivided into macro and microscale simulations. In macroscale simulations, a unit PEM fuel cell with interdigitated flow field configurations is simulated keeping in mind all the essential transport mechanisms, i.e., transport of species, ion
Common variants in genes encoding adiponectin (ADIPOQ) and its receptors (ADIPOR1/2), adiponectin concentrations, and diabetes incidence in the Diabetes Prevention Program.
Aims Baseline adiponectin concentrations predict incident Type 2 diabetes mellitus in the Diabetes Prevention Program. We tested the hypothesis that common variants in the genes encoding adiponectin (ADIPOQ) and its receptors (ADIPOR1, ADIPOR2) would associate with circulating adiponectin concentrations and/or with diabetes incidence in the Diabetes Prevention Program population. Methods Seventy-s

Signal Modeling and Detection in Nephrologic and Cardiac Applications
This doctoral thesis is comprised of five parts in the field of biomedical signal processing with focus on methods for use in hemodialysis as well as in cardiac applications. The problem of predicting hypotension is the main concern in the parts were data from patients undergoing hemodialysis are used. In Part I, a newly developed method for heart rate variability (HRV) analysis in the presence of

Phonetic markedness, turning points, and anticipatory attention
Phonetic markedness regarding linguistically relevant tonal patterns (Accent 2, boundary tones) in Central Swedish is discussed. Both tonal markedness and F0 turning points are assumed to be important cues for anticipatory attention to grammatical structure during speech processing. Empirical evidence from neuro- linguistic and psycholinguistic experiments for the assumed relation between anticipa

NMR Self-Diffusion Studies and Stability Studies of Emulsions
The aim of this study is to characterize emulsion systems by self-diffusion PGSE NMR methods. The specifics of the emulsions studied are all taken from the literature and they are of the W/O or O/W type stabilized with different emulsifiers. We have investigated what characteristics of emulsions that the NMR self-diffusion technique can shed light on. The diffusion behavior of the liquid inside th
Propagation aspects of vehicle-to-vehicle communications - an overview
Vehicle-to-vehicle (VTV) wireless communications have many envisioned applications in traffic safety, congestion avoidance, etc., but the development of suitable communications systems and standards requires accurate models for the VTV propagation channel. This paper provides an overview of existing VTV channel measurement campaigns, describing the most important environments, and the delay spread
Experimentation in Software Engineering: An Introduction
The purpose of Experimentation in Software Engineering: An Introduction is to introduce students, teachers, researchers, and practitioners to experimentation and experimental evaluation with a focus on software engineering. The objective is, in particular, to provide guidelines for performing experiments evaluating methods, techniques and tools in software engineering. The introduction is provided

CFD Modeling Considering Different Kinetic Models for Internal Reforming Reactions in an Anode-Supported SOFC
Fuel cells are electrochemical devices that transform chemical energy into electricity. Solid oxide fuel cells (SOFCs) are particularly interesting because they can handle the reforming of hydrocarbon fuels directly within the cell. This is possible due to their high operating temperature. The purpose of this study is to develop an anode-supported SOFC model, to enhance the understanding of the in
LTE Over Copper - Potential and Limitations
The densification of mobile networks in order to meet increased capacity demands is ongoing, needed and costly. A few papers have been published based on the insight that the fixed broadband networks offer a multitude of sites, for instance our homes, for potential small cell deployment providing backhaul capacity and power without site costs. However, in order to reach economical large-scale bene

Gränser som förenar – ett grundmotiv i postjugoslavisk film
Texten tar upp gränsmotivet i jugoslavisk film, framför allt genom att lyfta fram två filmer, Innan regnet faller (Pred Dozhdot, Mancevski, 1994) och Ingenmansland (Nicija zemlja, Tanovic, 2001). Dessutom diskuteras begrepp som jugoslavisk och postjugoslavisk film.
