The eutrophication of inshore seas, lakes and watercourses is mainly due to leaching of nitrogen and phosphorus (P) from agriculture. Many efforts are made to reduce the lea-kage of phosphorus in Sweden and the Baltic Sea countries. Phosphorus is also a finite resource and the mining of good quality raw material gets more and more difficult. Se-dimentation dams in combination with filters is one relatively new method to separate P from run-off and drainage water from agricultural land. This study was a part of an IVL Swedish Environmental Research Institute?s project which tests the capacity and func-tion for separation of phosphorus in four phosphorus filters.

Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.

The past and ongoing structural change in Swedish agriculture has led to an increasing number of large-scale farms. The biological factors associated with large-scale farming operations may cause increasing variability, risk and reduced yields due to sub-optimal timing and management of field operations. The theory of economies of scale suggests that largescale production may benefit from lower costs due to scale efficiencies. Thus, large-scale farms may face cost reductions in terms of long term inputs factors, e.g. agricultural machinery.

Legionella can be prevented, the question is how. This report is a degree in construction engineering education at Chalmers University in Gothenburg. A comprehensive written publication for Legionella-safe plumbing installations is not available and therefore requested. The purpose of this report is to present preventative measures against Legionella bacteria growth in tap water and in other systems where Legionella bacteria are a potential problem. Technical solutions are presented including how different systems function and what their advantages and disadvantages are.

Urbanization and the flight of the creative class drains the countryside when it comes to creativity and talent. Especially the young leave sleepy societies. Richard Florida claims that the city attracts the creative class and enables for economic growth to flourish. Robert Putnam adds to the picture by saying social capital might be equally effective as nourishment for growth. In Uddebo, a rural village in the south of Sweden one combines the two creating a vivid society where creativity flies high and ideas fertilize each other?s.

Bioethanol is one alternative energy fuel that can be produced from different types of biomass. Second generation bioethanol comes from fermentation of lignocellulosic material and can be seen as a more environmental friendly alternative as e.g. forest residues and agricultural by-products are used. To be able to use lignocellulosic biomass in ethanol production, it has to be subjected to different treatments first. In this study, aspen sawdust was used as lignocellulosic material.

The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.

The objective of this study was to get a better understanding of how the cultivation methods influence the vitality in Prunus avium. The purpose was also to examine if there was any differences in shoot growth and trunk expansion depending on the method of cultivation. To find the answer to this question a literature study and a case study has been done. The literature study concerns the concepts vitality and stress. Different definitions of these concepts are shown and their connection whit establishment is explained. In the background the species Prunus avium, and the four method of cultivation that are included in this case study are described. Measurements of the shoot growth and trunk expansion were made in this study, and as a complement to these methods, a visual estimate of the vitality was made.

Syftet med den här studien är att undersöka om utbildningens kvalitet har en signifikant påverkan på ekonomisk tillväxt. I uppsatsen tillämpas en regressionsanalys baserad på sekundärdata. Den beroende variabeln är real BNP per capita tillväxt vilken används för att mäta ekonomisk tillväxt. Den oberoende variabeln i fokus är testresultat från internationella prov och används som mått för utbildningens kvalitet. Kontrollvariabler i uppsatsen är initial BNP per capita, genomsnittlig utbildningstid, fertilitet, investeringar och graden av handelsöppenhet.

Today there is a keen competition between regions in the world for companies and inhabitants in order to improve regional development and economic growth. In many regions there is an active effort to create a good home base for companies and inhabitants. Since 2003 municipalities in nine counties in Sweden have come together in co-operative agencies in order to work towards more efficient regional development.This essay focuses on the relation between the state and the co-operative agencies in the regional development policy and which possibilities the state gives the co-operative agencies to pursue an efficient regional development policy, both legally and financially. I have researched and analysed this through models and ideas on how the state governs the administration and through the translation theory. The result of my study is that the co-operative agencies have a relatively large amount of freedom to make there own priorities, but the ability to act efficiently within regional development is limited..

For the past decades, culture has been given a role as a factor for local and regional development. But what is meant by development and in what ways culture can be of importance in this aspect can be unclear. This thesis examines the perception of the role for local and regional development of one specific cultural place and network ? the cultural cooperative Not Quite in Fengersfors, Sweden. I study the way the role as developer is expressed and interpreted in the discourse of the cultural workers who are members of the network and in the discourse of public cultural policy in the region Västra Götaland and in Åmål municipality.

The interest in businesses active on the countryside and their funding situation has increased in recent years. In a survey, conducted by Leif Berndtsson (2003), it was reported that there is a lack of external capital in rural areas. According to Berndtsson (2003) the lack of external capital inhibits the rural firm?s growth. The essay attempts to answer whether the shortage of external capital is a factor that inhibits development for rural businesses.

Abstract During the last 15 years, the former ?really existing socialist? economies have undertaken an extensive transition process. In this paper the development, measured as GDP growth, is analyzed using variables for economic policy. The analysis is both theoretical, taking as starting point current positions in academia, and econometrical with the linear regression model. We show that while economic policy variables of inflation, economic freedom and institutional quality affect economic growth, the results are not only the ones predicted by the theory.

The boiling properties are an important quality issue of the potato. In order to obtain adequate boiling properties the growth of the potato needs to be controlled and interrupted at the right time. However, it is difficult to determine when to stop the growth. Specific gravity can easily be measured and can sometimes be used as a tool for estimating the boiling properties. This report discusses different aspects of the specific gravity of the potato and how it can be used as a tool to determine the appropriate time for vine killing.
