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).

Den amerikanska armén har under lång tid haft doktriner som behandlat strid i bebyggelse medolika typer av motståndare, från sovjetiska divisioner som anfaller in i Västtyskland tillupprorsbekämpning i Mellanöstern och Afrika. Uppsatsen handlar om hur den amerikanska taktiskasynen på strid i bebyggelse har utvecklats från 1979 till 2003.Syftet med den här uppsatsen är att skapa en större förståelse för den taktiska utvecklingen somskett kopplat mot de grundläggande förmågorna verkan, skydd & rörlighet.En kvalitativ textanalys har använts som metod för att analysera de aktuella doktrinerna. Teorinutgår ifrån Doktrin för markoperationer och i synnerhet ifrån de grundläggande förmågorna verkan,skydd & rörlighet.Resultatet visar att användningen av dessa förmågor utvecklas med hänsyn till förväntadmotståndare och civilbefolkning. Utvecklingen av verkan går mot mer kvalitativa medel ochmetoder, motståndarens rörlighet har förändrats och så har också hans vilja att strida i bebyggelse.Användningen av assymmetriska metoder för att uppnå skydd är en ny metod som uppkommit.Värdering av den terrängen är däremot något som inte har förändrats..

AHA is a Swedish abbreviation of "reveal threatened park and avenue trees" and is a method to assess the conservation value of individual trees, mainly in the park environments but also in natural stands. This method has previously only been practiced in southern Sweden (Sörensson 2008). To see if this method could provide satisfactory results in northern Sweden, I have studied it in areas around the Umeå River. This was done by studying the relationship between trees with different classifications of conservation value (as classed by the AHA method) and their content of species (species richness and abundance). Insects were collected using trunk window traps in a period of 13 weeks during the summer of 2014.

Cultural heritages are environments created by humans that are considered to have a conservation value for the posterity. They can be seen as one of society's non renewable resources. It is important to have knowledge of how cultural heritages are affected by future climate changes.The water flow in Uppsala is estimated to increase during winter and decrease during spring and summer. Precipitation will gradually increase as well as the intense short period precipitation. The average temperature is estimated to increase as well.

Vargens återkomst har gett upphov till olika attitydsyttringar, boende i vargområden är i regel mernegativa till vargen än de som bor utanför dessa områden. Genom att mäta vilka attityder som finnstill varg kan forskare ge incitament till makthavare om hur vargförvaltningen upplevs avallmänheten.Den här studien är en kartläggning av forskningsläget under åren 2000 ? 2014 rörande attityder tillvarg i Sverige och Norge. De variabler/grupper av individer som forskare inom området använderför att mäta vem som har vilken attityd är jägare, djurägare, boende på landsbygd utanför vargområde, boende på landsbygd i vargområde, boende i stad med flera. Vi finner att studierna tar uppteorierna social representation, centrum och periferi och NIMBY (Not In My Backyard).

In today?s world urbanisation is an on-going process, cities are growing and becoming denser, and places for recreation gain value. Therefore, urban parks are much appreciated by people living in cities. When the first public parks where planned, their main function was to increase health, hygiene, education and social life. In the middle of 19th century the meaning of public parks to people?s wellbeing gained attention and parks were planned to provide space for lively activities. This paper focuses on parks? activities.

The complex, ever growing and changing environment, requires that today's organizations are dynamic and willing to change in order to stand competitive.This awareness has made change number one priority in almost all organizations' agenda.We live in a world that is constantly changing, yet many organizations fail to change successfully. When a change occurs in complex environments with multiple stakeholders, it immediately increases the complexity and the challenges of the change process.A complex situation may arise when, for example, partial outsourcing of the corporate information system infrastructure. Two of the most difficult challenges that organizations face today is to conduct a successful change process and managing the effect of a change, such as arising expectations. It is very common for change in an organization not to achieve the desired result or that they even fail. There may be a lot of reasons for these failures.

The number of people of getting allergic symptoms is increasing and the reasons are considered to be many. The human have changed their habits and spend more time indoor. In combination with new building technologies where denser housing constructions and new materials this causes bad indoor climate contributes to a higher occurrence of allergiesThere are several courses of action to deal with this problem. One action is by choosing allergy-free interior surface materials. An allergy-free material emits low concentrations of harmful substances resulting in a great indoor air quality.

The main object of this diploma work thesis is about how computer programs can bea tool to use for work on stormwater investigations. The advantage of using acomputer program compared with calculations made by hand is evaluated anddiscussed. The computer programs that have been used for studies and a sequence oftesting of the possibilities are Autodesks Storm and Sanitary Analysis and DHIs MikeUrban.Focus on sustainable development now permeates the building industry. As a resultstormwater investigations have been conducted in an increasing extent the recentyears. Stormwater is water produced due to precipitation, such as rain and snowmelt.Stormwater investigations normally contain descriptions of existing land use, plannedland use and suggestions of measures and technical solutions for the future disposal ofstormwater.The initial part of the thesis consisted of literature studies on stormwater andstormwater investigations to understand the science.

Göteborg är en av Europas mest segregerade städer (Andersson m.fl. 2009, s. 7); inkomstsvaga, ofta utlandsfödda bor i hyresrätter i förortsstadsdelar medan de ekonomiskt starka har sina egnahemsområden eller bor i innerstaden. I jämförelse med andra liknande städer i Europa är Göteborg starkt segregerat. Mer än hälften av regionens bostadsområden består till 90 procent av bara en upplåtelseform, de flesta av dem är egnahemsområden, vilket placerar Göteborg i en särställning.

Women today feel that their urban surroundings are unsafe, and because of that they use different strategies to reduce the risk of being exposed to criminal acts towards them. The focus of this study is to develop an understanding of the insecure feeling that women feel and what that feeling might originate from. By using previous research and theories we have been able to incorporate a gender perspective on the study this because the gender role is central to understand women?s feelings of insecurity. The purpose of the study was to develop a deeper understanding of women?s sense of safety and insecurity.The central questions of the study are1.

Several cities have implemented various projects to improve traffic safety in city centers.During 1970s and 1980s the city centers changed as the suburbs grew and large shopping centers were located outside the center. At the same time, several projects were initiated with construction of pedestrian streets and restriction of traffic in the center. In year 1994,shared-used areas were introduced in Sweden and these areas are often used in center environments.In Sweden, municipalities are responsible for integrating security in public places and in comprehensive plans and detailed development plans. The National Board of Housing,Building and Planning is the authority for administrating planning issues and develop general guidance about planning. Traffic is one of their key issues, although today there are no concrete guidelines from the National Board of Housing, Building and Planningfor the design of traffic safety in city centers.Traffic safety in city centers affects many people because the city center is a public place.It is therefore important that there are current guidelines available that are helpful for changes and improvements in traffic safety in the city center.The purpose of this report is to formulate guidelines for planning city centers from a traffic safety perspective.

In the centre of Bromma, east of Brommaplan is the part of Bromma named Riksby. Riksby was built in the early 1940:s as a part of the westward expansion of Stockholm. Other places that were built at the same time was for ex. Stora Mossen and Abrahamsberg. This work is about the outdoor environment of the housing co-operative of Brickbandet.

The aim of this paper is to empirically examine the ideological trends and positioning of the Swedish liberal party with the Danish social liberal party. This paper also aims to analyze the reasons behind the trends. By examine the development in these two Nordic liberal sisterparties, this paper contributes to our understanding of why and how party change is initiated. The paper commences with an intuitive notion that the Swedish party has in fact, made a lurch towards the right, during the past ten to fifteen years while the Danish party has retained their social-liberal position in the centre of the Danish political spectrum. The questions then asked are: can this hypothesis be verified empirically? If so, how can this phenomenon of divergence, be explained?The method used in this thesis is process-tracing and the empirical material does to a large extent rely on interviews with central agents as they are specified in the theory of each party.

Arbetet är en teoristyrd fallstudie på Amiralen och Slottsbackens handelsområden, med syfte att undersöka möjligheten att skapa en trevligare visuell externhandelsmiljö med hjälp av förtätning och funktionsintegrering. För att göra detta jämför och förenas handelsperspektiv på platsen med kända stadsbyggnadsbegrepp. Arbetes teori grundar sig på Jane Jacobs syn på staden som centrum för mångfald, Joel Garreaus teoretiserande av externhandelscentrumen utifrån begreppet Edge Cities, samt en syn på den täta staden som en hållbar stad. För att skapa den mångfaldiga staden krävs en inplantering av olika funktioner med olika tidsscheman, så att gaturummet ständigt befolkas av en varierande sammansättning människor. Vid sidan av detta förespråkas små kvarter, en tät stad med hög koncentration av människor och en bebyggelse med blandad bebyggelse från olika tidsåldrar.
