Two ecological models of nitrogen processes in treatment wetlands have been evaluated and compared. These models have been implemented, simulated, and visualized in the Modelica language. The differences and similarities between the Modelica modeling environment used in this thesis and other environments or tools for ecological modeling have been evaluated. The modeling tools evaluated are PowerSim, Simile, Stella, the MathModelica Model Editor, and WEST. The evaluation and the analysis have been performed using McCall?s factors for software quality (McCall et al, 1977), a correlation analysis and the Constant Comparative Method (Glaser&Strauss, 1999).

Introduction: The current research shows that cannabis use is increasing, while alcohol use is decreasing in many countries. The reason for the increase is considered to be the increased availability and that adolescents attitudes towards cannabis has become more liberal. Aim: This qualitative study aimed to examine adolescents attitudes and knowledge about cannabis. Methods: Data has been collected from focus group interviews with adolescents aged 15-18 years, in a west Swedish municipality. Participants were recruited through visits to secondary and upper secondary schools.

Mitt syfte med projektet är att vitalisera stadsdelen Husby i nordvästra Stockholm. Bryta upp zonerade områden och addera fler och varierade funktioner som definierar nya stråk, länka samman omtyckta områden och överbrygga platser som upplevs otrygga. Sammantaget ger det förutsättningar för ett mer levande stadsliv som attraherar fler att vilja bo, bo kvar och göra bostadskarriär i Husby.Centrala begrepp i projektet är mångfald, trygghet, flexibilitet och hållbarhet. Jag har arbetat med att identifiera, bevara och utveckla kvaliteter i kombination med att öppna upp befintlig bebyggelse som präglas av upprepning, slutenhet och rationella byggmetoder samt addera ny bebyggelse för att få en större mångfald och ett mer flexibelt utbud av både lokaler, bokaler och bostäder men även genom att analysera och bearbeta områdets struktur. Fokus har legat på de trafikseparerade miljöerna och hur de kan vidareutvecklas genom att bland annat addera gångvägar och skapa nya stråk längst tillfartsgatorna och samtidigt bevara kvaliteter som de nivåseparerade korsningarna mellan gångvägarna och bilvägarna erbjuder med säker skolväg och en trygg bilfri miljö för barnen..

Bornsjön är Stockholms viktigaste reservvattentäkt och kan tillgodose staden med dricksvatten i flera månader om Mälaren skulle slås ut. Det är därför viktigt att Bornsjön håller en god vattenkvalitet. Under de senaste åren har vattenkvaliteten avseende totalfosfor i Bornsjön försämrats. Hög belastning av fosfor kan leda till övergödning i en sjö. När en sjö är övergödd uppstår ökad syreförbrukning som kan leda till syrebrist.

I denna uppsats undersöks ett flertal ortnamnsformer som förekommer i olika tyska, slaviska och skandinaviska källor och betecknar ett och samma ställe, nämligen staden Wolin belägen på sydspetsen av ön Wolin i polska Pommern. Syftet med arbetet är dels att fastställa etymologin av två av Wolin-namnen, at Jómi och Jómsborg, dels att förklara hur alla ortnamnsformer som betecknar staden Wolin hänger ihop och bestämma vilka faktorer som orsakade en sådan namnmångfald. Undersökningens material utgörs framför allt av de Wolin-namnformer som förekommer i de skandinaviska och de med dessa relaterade tyska källorna. Materialet analyseras i stort sett enligt den traditionella namntolkningsmetoden. Det visar sig att formen at Jómi sannolikt härstammar från det pommerska naturnamnet *J?ma (? j?ma f.

The landscape can be something that you rest your eyes on, something that goes quickly past outside the windscreen or the place for the daily work. To me, landscape is everything around us ? the city, the field and the forest. But what is landscape for you? What does the idea of the landscape stand for? How does our view of the landscape become influenced of the place where we grow up? And the differences between peoples different views of the landscape ? what does they depend on? My point of the view for this paper is that the landscape ideals mostly depend on the landscape where you grow up and that it depends less on the differences between the individuals. As a landscape architect the idea of the landscape is the essential. The more we learn, the more we realize how complex it is, but deep down we always have our own experiences and memories and that shapes our personalities.

The nitrogen cycle in freshwater bodies is complex and consists of many separate processes affected by a number of important factors for example oxygen concentration in the water, temperature and circulation. Knowledge of the different components of the nitrogen cycle exists; however, a complete and comprehensive picture is difficult conceptually as well as theoretically. The available literature illustrates that the research on nitrogen and the related freshwater processes is still associated with high uncertainty of how much of the supplied nitrogen from the catchment is transported with the water versus and how much is lost due to denitrification, sedimentation or uptake by plants. This report is an interdisciplinary survey of Nitrogen discharge permitting. The research focuses in particular on the decision-making process, the levels of scientific standard and the administrative framework.Application for Nitrogen discharge permits are decided by the Environmental Court with council from their own experts as well as relevant government authorities and organisations.

Syftet med denna studie är att analysera fyra tågföretags hemsidor (SJ, JR East, JR Central och JR West) från Sverige och Japan i relation till två teorier om kulturella skillnader för att se vilka eventuella skillnader i utformandet av hemsidorna som kan komma att finnas. Baserat på Würtz och Marcus och Goulds parametrar går det att se att hemsidorna skiljer sig åt vad gäller användandet av animationer; många på JR-företagens sidor, ej förekommande på SJ:s. Det fanns också skillnader i värderingar; SJ betonar frihet, framtid, ungdom och direkta resultat medan JR-företagen framhäver historia, tradition, officiella logotyper, professionalism och långsiktighet. På JR Wests sida visas könsroller tydligt, medan dessa är utsuddade på SJ:s sida. Informationen på SJ:s sida ä relativt lättillgänglig, men på JR-företagens sidor krävs fler klick för att komma dit man vill.

Cameraria ohridella, the chest-nut leaf miner, is a new pest in Sweden. These moths make leaf mines on chest-nut trees, preferably on Aesculus hippocastanum, which results in brown blotches on the foliage and early loss of leaves. Since the first observation in Macedonia in 1985 it has spread rapidly through Europe. The moth arrived in Sweden in 2003 when it was observed in Malmö and surrounding areas. In this paper a literature study describes the morphology and life cycle of the chest-nut leaf miner. Further more a test with pheromone traps examining the number of generations in Sweden is shown.

This thesis investigated the possibilities to resume cultivation of an old manor house built of timber and what this would mean from an energy and moisture perspective. The building in this case study is named Sofiedals mansion and was built in 1858 in Valbo 11 kilometers west of Gävle.The structure of the house was documented and used as a starting-point for carrying out calculations focused on energy and moisture aspects. With the help of a number of computer programs and a conducted air tightness test, the buildings energy consumption were calculated and compared with the current building regulations.In addition, the building was analyzed considering energy retrofitting and what it meant for moisture problems. The energy retrofitting consisted of additional insulation, decreasing the buildings permeability through air sealing; window and door replacements. When a building is equipped with natural ventilation it is difficult to know its precise performance and how an energy retrofitting affects it.

In the 1940s, 50s and 60s the two youth movements of the beats and the hippies emerged in the United States. Disagreeing with the progressive positivism of the previous generations these youths were part of a counter culture that adhered to an ideal of living in the present.Alan Wilson Watts (1915?1973), most known for his popularization of eastern philosophy and religion in general and Zen-Buddhism in particular, became one of the most influential and well-read advocates of the new movements. Drawing upon eastern philosophy and religion as well as modern psychology, Watts challenged the western world view by rejecting the dualism of self and environment, arguing that man is one with God and nature and claiming that nothing exists but the present experience here and now.Based on Watts? view of man and reality, and in the context of the emerging youth movements, this study examines Watts? criticism of western culture and society as well as his view on happiness and the possibility of a better life for the individual living in the west.The study shows that, according to Watts, the root of the problem facing western society lies in man?s incapability of distinguishing concept from reality, preferring abstract ideas and symbols to the experience present in everyday life.

This thesis aims to study obstacles which Turkey faces regarding EU accession. The main focus will be at the historical context and background information to clarify Turkey-EU relationship and institutional aspects such as; the Copenhagen criteria will be analyzed. Interaction between identity politics and Turkeys Europeanization project will be examined by analyzing arguments regarding this issue. The historical context is important for realizing in how Turkey's negotiation process is affected and how the process is evolved. By examining this, a more transparent understanding is going to develop in the issue of why Turkey never will be able to identify itself with the EU.Analysis regarding why Turkey as a secular state develops into an increasingly Islamized state is highlighted.

In 1896, a French cinema pioneer named George Méliès demonstrated that an object could be set to motion by changing the objects shape or movement frame by frame. But it was not until the early 1900s that this specific genre of filmmaking became a great success. The animations were essentially short and were animated and published in The United States of America. The interest in animated movies began to increase, not only in the west, but also in Europe and Asia. The art of animation grew especially popular in Japan, and emerged as a parallel to Japanese comic books known more commonly as Manga.The history of Japanese animation is not as commonly known as the history of American animation.

This is a final thesis on the landscape architecture program at the Swedish University of Agricultural Sciences. It is the end of five years of studies and comprises 30 ECTS. This thesis is about the camp area Sjöröd, located by Gyllebosjön (the Gyllebo Lake) on Österlen in Skåne, southern Sweden. The thesis results in plan for how the area could be used in the future. It also raises the questions; what scouting of today is, how it is to be developed for the future, what a camp is and which aims the scout movement has set up for itself and its activities. The thesis also treats what is typical for Skåne, for Österlen and for the area around Sjöröd as a starting point.

This thesis has focused on the possibility to use a satellite image method developed by Metria Mijöanalys to identify stands that are wrongly registered in Holmen Skogs database. The method is only intended for identifying stand with poor descriptions in Holmen?s database that needs to be updated and not for updating the stand information. The study area is located several km west of Hudiksvall on the borderline between Gävleborgs- och Västernorrlands län. The area is covered by a SPOT image from 2005. By which Metria Miljöanalys has made estimates of forest parameters for all stands in the area, and compared them with corresponding estimates according to the stand database.
