Microsphere-based constitutive models are a helpful tool in the modelling of materials with a microstructure composed of contributing elements directionally arranged. This is the case, for instance, for fibred soft tissues. In these models, the macroscopic mechanical behaviour is obtained from the integration of the micro-structural contribution of each component (e.g. each fibre) over the surface
The emergence of new modes of production, referred to as flexible specialization, post-Fordism or neo-Fordism, has played an important and controversial role in the debate among economic geographers and industrial sociologists. In the discussion assumptions have been made about a process of up-skilling of the work force. In this study a random sample of 351 white- and blue-collar workers in eight
This thesis has been taking a starting point from a micro-level that focuses social structures, ethnic segregation and processes of development as phenomena from different levels of perspectives. The research focuses on housing-conditions in the urban room and take a starting-point in 1992 when an increased number of immigrant households, depending on social welfare, moved into Herrgården (Manor-H
Global problems such as atmospheric change, acid rain, and water pollution in surface and subsurface environments dominate discussions of world environmental problems. In this thesis the roles of hydrologic processes and hydrogeochemical processes are investigated through development, modification, and application of models for addressing point and non-point source contamination of water. The move
Sedimentological and morphological changes on the upper and lower shoreface during relatively stable sea-level highstand conditions have been investigated in the Pomeranian Bight, southern Baltic Sea, at time scales ranging from storm events to millennia. In order to cover that variety of time scales, different methods have been applied. Seasonal variations in the morphology of the upper shoreface
Global extinction of a species is sadly irreversible. At a local scale, however, extinctions may be followed by re-invasion. We here show that this is not necessarily the case and that an ecological community may close its doors for re-invasion of species lost from it. Previous studies of how communities are assembled have shown that there may be rules for that process and that limitations are set
Time-resolved VUV laser spectroscopy has been performed to determine radiative lifetimes of several elements in atomic-beam systems. VUV radiation was generated by means of resonant four-wave mixing and stimulated anti-Stokes Raman shifting. Several methods to produce free atoms are presented and different techniques to determine radiative lifetimes are discussed. Doppler-free laser spectroscopy
A new, two-layer canopy module with thermal inertia as part of the detailed snow model SNOWPACK (version 3.2.1) is presented and evaluated. As a by-product of these new developments, an exhaustive description of the canopy module of the SNOWPACK model is provided, thereby filling a gap in the existing literature. In its current form, the two-layer canopy module is suited for evergreen needleleaf f
Helsingborg, a coastal city in southern Sweden, initiated a long-term redevelopment project called H+ in 2009, aiming to convert industrial harbor space in the city's south into a new, livable urban neighborhood and city center. The project aims to create an open and ‘tolerant city’ in Helsingborg over the next twenty years. In 2010-2011, H+ used an open-source planning method as a strategy to inc
It has been known from multi-zone simulations that HCCI combustion can be significantly affected by temperature stratification of the in-cylinder gas. With the same combustion timing (i.e., crank angles at 50% heat release, denoted as CA50), large temperature stratification tends to prolong the combustion duration and lower down the in-cylinder pressure-rise-rate. With low pressure-rise-rate HCCI
The impact of pH coupled to process design for the conversion of the energy crop Arundo donax to ethanol was assessed in the present study under industrially relevant solids loadings. Two main process strategies were investigated, i.e. the traditional simultaneous saccharification and co-fermentation (SSCF) and a HYBRID design, where a long high temperature enzymatic hydrolysis step was carried ou
Muscle contraction studies often focus solely on myofibres and the proteins known to be involved in the processes of sarcomere shortening and cross-bridge cycling, but skeletal muscle also comprises a very elaborate ancillary network of capillaries, which not only play a vital role in terms of nutrient delivery and waste product removal, but are also tethered to surrounding fibres by collagen "wir
Populärvetenskaplig sammanfattning: Jordens klimat står under ständiga variationer och förändringar, och det är inte alltid lätt att sära på orsak och verkan bland den mängd av faktorer som styr klimatet. För att kunna reda ut ursprunget till de förändringar som sker, måste de bakomliggande processerna vara väl kända. Sedan är det möjligt att genom matematiska modeller uppskatta de individuella prSeveral studies have analysed the relationship between Normalised Difference Vegetation Index (NDVI) and radiative surface temperature. A main goal for most studies have been to find the best method for carrying out land cover classifications and to study land cover changes, based on a combination between the two parameters. Since atmospheric components have a significant influence on both paramet
The European energy market has undergone a large transformation in the last 20 years. It has gone from being a market strictly controlled by the Member States and dominated by state monopolies to being a privatized market under the rules of the market economy. This process has as its main aim to create a free and unified European energy market characterized by productive competition. A number of s
The climate on earth is changing and to deal with this problem, a method called climate change adaptation is used. Some researchers consider this a new method while others claim that it is a version of risk management. Based on this discrepancy, this master thesis aims to answer the following research question “What are the differences and similarities in practice between climate change adaptation
2006 genomfördes en reform av den svenska asylprocessen. Det tidigare systemet hade utsatts för stark kritik, och särskilt överklagandeinstansen, Utlänningsnämnden, hade blivit en symbol för en godtycklig, och samtidigt restriktiv asylpolitik. I och med reformen ersattes Utlänningsnämnden av tre Migrationsdomstolar och en Migrationsöverdomstol. Det uttryckliga målet var att öka öppenheten och rättIn 2006 a reform of the Swedish asylum process took place. The former system had been the object of strong criticism, and especially the appellate body, the Aliens Appeals Board, had become a symbol of an arbitrary, and at the same time restrictive asylum policy. In the reform the Aliens Appeals Board was replaced with three Migration Courts and one Migration Court of Appeal. The outspoken aim was
Economic sanctions are defined as the exercise of pressure by one state to produce a change in the political behaviour of another state. Traditional economic sanctions are directed at the entire population of a state whilst targeted sanctions are directed at a state’s individuals. This thesis discusses the application of economic sanctions against Iran by the UN, the EU and the United States. Econ
In this study, physical properties of a small glacier in Kebnekaise Mountains, northern Sweden, are investigated in order to evaluate its erosionai capacity. By definition, glacial cirques are cut out by erosion by cirque glaciers. In areas characterized by low precipitation and pemafrost, small glaciers have very low erosional capacity. Is it possible that a small glacier can excavate a cirque fo
