Hydropower is the main source of electricity production in Iceland. In 2005, 80.8% of all electricity was generated by hydropower (7015 GWh). Hydropower production is affected both by variations and changes in discharge. This thesis focuses on studies of the trends and the variability found in records of discharge and climatic variables, combined with watershed modelling and an analysis of a proje
This work presents an account of social power based on recent advances in social ontology. It is argued that a conceptual analysis of social power can be informed by developments in social ontology, but also that this field can be enriched, and in fact requires, an analysis of this central social concept. Social power is dependent on the existence of various kinds of social phenomena, such as ins
Ethanol produced from cellulose is a promising future alternative fuel. The production process has three main steps: (i) pretreatment of raw material to increase degradability; (ii) enzymatic hydrolysis of cellulose to produce glucose; (iii) fermentation of glucose into bioethanol. This thesis contains studies with the aim to improve the enzymatic hydrolysis of cellulose from steam pretreated spru
The adsorption of lipases to solid surfaces was studied by means of in situ ellipsometry. In addition, the activities of the adsorbed lipases were measured in situ, by the hydrolysis of p-nitro phenyl acetate. Adsorption was made to methylated silica surfaces with varying degree of wettability as well as to clean silica surfaces. Lipases from Humicola lanuginosa (HLL) the wild-type (WT) and a m
The topic of this work is simulations of porous materials and transport phenomena at a mesoscopic length scale, i.e., a length scale larger than an individual atom but smaller than the continuum. The porous material studied is a membrane used in fuel cells. Mass transfer has also been studied in the membrane. Heat and mass transfer has been studied in parallel plate channels, first in saturated ch
Clubfoot is a congenital disorder, affecting about one of 1000 children. Treatment consists of initial correction of the deformity, followed by prolonged orthosis treatment to maintain the correction obtained. There are several different treatment options. Outcome studies, using reliable and valid instruments are rare. In this thesis an assessment instrument, Clubfoot Assessment Protocol (CAP) wa
The main aim of this thesis is to explore young women’s lived experience of the body, which, on one hand, is viewed as deviant – the disabled body – and, on the other hand, is viewed as accomplished – the sporting body. The questions posed in the thesis are the following: how do the young women handle the two subject positions that emerge as a result of the perception of them as respectively devia
The first purpose of this dissertation is to describe and discuss the development of the Iron Age society in Scania. The second purpose is to discuss the relations between Scania and the neighbouring areas. The Iron Age society was hierarchical and ruled by different types of leaders, usually cheiftains or kings. To maintain and develop the social system different social groups acted in society.
Laser based diagnostic tools have had an exploding impact on fundamental as well as applied research in a number of disciplines, such as biomedicine, physical chemistry etc over the last decades. Whereas fundamental research often investigate phenomena in extreme conditions, applied research aims at performing in-situ measurements, in order to understand the many aspects and entangled phenomena th
The aim of the present study is to examine the polytypia (morphological variation) and semantic differentiations of the verb in Vitsentzos Kornaros' Erotokritos, to understand how these shape poetic style. We examine the stems and the endings in the imperfective active forms. Moreover, we investigate the augmented forms because at an early stage we found that Kornaros employs a degree of poetic li
Popular AbstractI början på 1990-talet drabbades Sverige av en mycket djup ekonomisk kris. Den svenska nittiotalskrisen uppfattades inte som en tillfällig konjunkturnedgång utan som symptom på grundläggande systemfel i Sveriges ekonomi. Många bedömare menade att den s.k. svenska modellen med stor välfärdsstat och höga skatter hade försämrat marknadsekonomins effektivitet och gjort att Sverige unde
Within the science and technology centre (STC) movement there exists explicit aims and ambitions to enhance visitors’ interest in and knowledge about science. Meanwhile, several researches question the choice of the scientific content in exhibitions when arguing that a too unproblematic view of science commonly is presented. But what images and aspects of science are visitors actually confronted w
This thesis mainly focuses on methods for improving and evaluating Spatial Data Infrastructures (SDIs). The aim has been threefold: to develop a framework for the management and evaluation of an SDI, to improve the accessibility of spatial data in an SDI, and to improve the cartography in view services in an SDI. Spatial Data Infrastructure has been identified as an umbrella covering spatial data
The aim of this thesis is to offer a contribution to the understanding of marketing work. In orthodox, mainstream marketing management literature, the work of marketing is commonly depicted as a fairly straightforward practice, technical in character, neutral in terms of social values and ideologies, operating within an objective and pre-given world. A counter picture to this idealised view of mar
Local treatment with the aim to destruct tissue by heating (thermotherapy) may in some cases be an alternative or complement to surgical methods, and has gained increased interest during the last decade. The major advantage of these, often minimally-invasive methods, is that the disease can be controlled with reduced treatment trauma and complications. The extent of thermal damage is a complex fun
Most components in use in our society have undergone a machining process at some stage within its manufacturing cycle. As a result, the economics of the machining process plays an important role in the manufacturing costs. There are several reasons for developing a rational approach to material removal, such as improving cutting techniques, producing products with enhanced precision, and increasin
Fracture incidence is higher in urban than in rural inhabitants. Background factors such as physical activity and workload may have an influence on the tendency to fall, leading to fractures. We found that elderly women with a recent fracture of the distal radius appear to have impaired balance, an impairment that seems to normalise with time after fracture. The aim of this study was also to get n
The aim was to study the long-term consequencies of vesicoureteral reflux and reflux nephropathy (RN) in adults, with regard to radiological progression, urinary tract infections, renal functional impairment, hypertension, and to determine if the extent of renal damage can predict the outcome. Attempts to differentiate between acquired and developmental renal damage were also made. 115 patients wi
This PhD thesis reports on investigations of the atomic scale structure of model catalysts relevant for the catalytic oxidation of CO and methane over Pd, and NOx reduction over silver-alumina, important reactions in automotive catalysts. By using complementary experimental techniques such as X-ray Photoelectron Spectroscopy, High Pressure X-ray Photoelectron Spectroscopy, Surface X-ray Diffractio
The present thesis examines differences in post-decision processes between members of groups and individual decision makers. The empirical studies employed a decision theoretical framework based on Differentiation and Consolidation (Diff Con) Theory. Diff Con theory proposes that decision makers strive to achieve sufficient differentiation in their evaluation of one alternative versus competing al
