The fundamental question posed in this study is how to approach the construction sector in order to cover its wide scope of activities, its great variety of actors and the external influences on it from the market and institutional environment. Construction includes such diverse economic activities as new production and as repair/maintenance, itinerant production and stationary manufacture, the pr
In the search for high efficiency combustion systems pulsating combustion has been identified as one of the technologies that potentially can meet the objectives of clean combustion and good fuel economy.Pulsating combustion offers low emissions of pollutants, high heat transfer and efficient combustion. Although it is an old technology, the interest in pulsating combustion has been renewed in rec
The way in which the cortical cytoskeleton associates to the plasma membrane (PM) must be elucidated to understand the structural dynamics of many processes in the plant cell. In the present study, isolated cauliflower (Brassica oleracea L.) PM vesicles were used to characterize membrane/cytoskeleton interactions. Both actin and tubulin were shown to copurify with PM vesicles and this copurificati
Various aspects of the adsorption of molecules on metal surfaces have been studied making use of different properties of high resolution core level photoemission. A thorough investigation has been performed of the ordering and the site occupancy of CO overlayers on Rh(111). CO has been shown to adsorb in on-top and three-fold-hollow sites. The distribution of the molecules between these two sites
Degradation of organic matter takes place in many processes within a wastewater treatment plant (WWTP). The need for optimisations and extended degradation processes for both organics and nitrogen will increase as outlet demands are strengthened and increasing loads are desired. The purpose of this work was to study the degradation of organic matter at WWTPs within two areas in particular; 1) d
Today's handheld computing devices equipped with novel wireless network technologies can provide their users with features such as mobility, multimedia support and group communication. On the other hand, the administrative effort required to enable all these features increases beyond the level that an ordinary user can manage. Ad hoc networks, being able to quickly organise themselves without user
The cavitation phenomenon has today become a keystone for different areas of science and technology including various industrial processes and medicine. Recently increasing interest and much attention have been paid to study this phenomenon. The last two decades have witnessed the development of numerous devices for different important applications of considerable practical interest, and the rang
This thesis is comprised of five papers that are all related to the subject of financial time series. We study statistical aspects of conditional heteroskedastic models commonly used in modelling financial volatility. Paper I discusses the performance of commonly known information criteria in the presence of various GARCH processes. The investigation has been performed using Monte Carlo simulatio
Popular Abstract in Swedish Delaktighet i biståndsbedömning av äldre personer inför kommunalt bistånd. Äldre personers, familjemedlemmars och biståndsbedömares upplevelser. Den äldre generationen förväntas snabbt öka i Sverige och i övriga Europa under de kommande årtiondena. De äldres vårdbehov kommer att öka och därmed förväntas svårigheter att ombesörja tillräcklig kommunal vård och omsorg. ÅlAim: The overall aim of this thesis was to illuminate older persons' experience of becoming in need of public home help and their family members' experience of this situation. Further, the aim was to illuminate experiences of participation in the needs assessment process of older people and influence on decisions about public home help from the perspective of older needs-assessed persons, their fa
The field of wireless communication is growing rapidly, with new requirements for the next generation of mobile and wireless communications technology. In order to achieve the capacities needed for future wireless systems, the design and implementation of advanced communications techniques such as multiantenna systems is required. These systems are realized by computationally complex algorithms, r

Dwarf galaxies are a key component in understanding the evolution of galaxies and provide tests on the standard cosmological $\Lambda$ Cold Dark Matter model. According to the formation hierarchy, dwarf galaxies are the pieces that create all galaxies. Our current understanding of dwarf galaxies faces discrepancies between theory and observations. These problems are mostly due to incompleteness in
Introduction: Many countries in the world are still facing high maternal mortality rates and women still die due to preventable pregnancy- and birth-related causes. This could be prevented with an improvement in the quality of care and yet many countries, especially in the rural areas, have challenges in doing so. In order to understand why is care given in certain way, more qualitative studies ne
Uppsatsen undersöker frågan samebyars avtalsrätt. Frågan är intressant eftersom samebyar i viss mån kan jämföras med ekonomiska föreningar. Juridiska personer har vanligtvis avtalsfrihet, men samebyars möjligheter är begränsade. Enligt ren-näringslagen får samebyarna inte ingå avtal om upplåtelse, och det är endast rege-ringen som får förordna om ett upphörande av renskötselrätten.

While these villages are, in legal terms, comparable to economic association and thus possess legal personality, their ability to enter into agreements is subject to legal constraints. Unlike typical legal entities Sámi villages are not free to contract as they wish. Under the Reindeer Husbandry Act, Sámi villages are prohibited from g
Bread dough was studied in relation to three Andean grain flours, quinoa (Chenopodium quinoa), amaranth (Amaranthus caudatus) and canahua (Chenopodium pallidicaule), as partial replacements for wheat flour with the perspectives of dough and breadmaking. This thesis deals with the understanding of both dough as a complex system, consisting of various water-filled polymers, and dough as a viscoelast
This thesis contributes to research on experimental and behavioral economics as well as auction theory. It consists of five papers.The first paper, Differences Attract: An Experimental Study of Focusing in Economic Choice, studies whether individuals' decisions are affected by focus effects. The focus effect suggests that individuals focus more on an attribute that has a larger difference among th
In this paper we call into question the relationship between development, inequality and territory in the current context of globalization and within the framework of public policies designed, supposedly, to benefit those social actors with fewer resources. In order to do this, we focus on a case study in the northeast of the province of Misiones, Argentina. Here tobacco production, forestry and a
The EU governance of food safety and GM food and feed has gone through significant changes since the BSE crisis and food scares during the 1990s. This work focuses on one particular new feature; the role of stakeholders representing the food chain: biotech associations, farmer organizations, food and feed processors, consumer organizations and environmental NGOs. These stakeholders are not merely
För att skapa matematiska beskrivningar av fysiska fenomen inom bland annat naturvetenskap, teknik och medicin används ofta partiella differentialekvationer. Listan med tillämpningar kan göras hur lång som helst: sådana ekvationer kan beskriva hur en snöflinga bildas, hur strukturer deformeras när de utsätts för mekaniska krafter, hur partiklar interagerar på kvantnivå, hur blodet flödar i hjärnanSplitting methods are widely used temporal approximation schemes for parabolic partial differential equations (PDEs). These schemes may be very efficient when a problem can be naturally decomposed into multiple parts. In this thesis, splitting methods are analysed when applied to spatial splittings (partitions of the computational domain) and physical splittings (separations of physical processes)
