Dagvattendammars reningseffekt : påverkande faktorer och metodik för statistisk modellering

Storm water is defined as runoff from precipitation such as rain or Snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

Assessment of food retail business sustainability : the case of Konsum Värmland

Public concern and the need of responsible way of doing business have brought forward the issue of sustainability at the forefront of discussion in the last decade. Even though, food retailers are playing an important role in the economy, they are exposed for criticism by media and consumers for any socially and environmentally irresponsible business practices because, the potential environmental and social impacts from their operations are significant. These impacts need to be recognized and properly addressed. The main objective of this study was to assess the sustainable business management of a cooperative food retail business in Sweden, known as Konsum Värmland (KV). The necessary data and information on history and status of KV, and its practical activities concerning the implementation of sustainable development programs as well as the motivation and challenges encountered by KV during the implementation were gathered via reviewing different documents, research papers and press releases; interviewing decision makers and other personnel in KV and other researchers from Swedish University of Agricultural University who have investigated KV.

Bygglovsbefriad vindkraft till småhuset : -Ur ett tekniskt och ekonomiskt perspektiv

In connection with the property crises in many countries, caused by the financial crises, people are now more aware of the risks involved in poor property-investments. The unusually cold winters along with extreme prices of electricity in Sweden in recent years has also contributed to increased interest in energy-efficient buildings.The process of developing a modern family home in Kiruna, Sweden is presented the first part of this paper. The house has been designed to withstand very high stresses from Snow, low energy consumption as well as a high standard of living comfort. Aspects of the house covered here involves everything from construction, heating and ventilation to sanitation. Each of these areas is presented based on their underlying, scientific methods or theories.

Boulognerskogen : förslag till program för en stadslekpark

Boulognerskogen is a park in the central of Skövde that have had a health resort, paths for strolling, outdoor-bath, outdoor-sport areas and events. During the 1970:th there was a lack of interest for the park and very few visited it. By a motion from a resident in Skövde wich proposes that a city playground will be build in Boulognerskogen gave me an opportunity to investigate how the potential of the park can be used to create a funny and nice place to visit for children in company with adults. By a program that contains the main goals and design program for a city playground in Boulognerskogen, I wanted to present a proposal that could meet childrens needs to play and to use the conditions of the place to create places to play in, and where children in company with adults could be together. To reach this, I wanted to try different methods that could lead to a proposal that was well supported by children and adults, and wich was possible to use by the local authority in their further actions. The methods that I used was therefor an important part of the work. I have choosen to define the concept "city playground" as a greater playground situated in the center of the town that are suitable for outings and as a meetingplace, with a varation in playground attractions and promote children and adults to be together, aiming at younger children in the ages of 1-10 years in company with adults, but should also give space to activities of other groups.

Klimatologisk studie av cyklonbanor över Europa med koppling till snöförhållanden i norra Sverige

ReferatKlimatologisk studie av cyklonbanor över Europa med koppling till snöförhållanden i norra SverigeJakob InghammarUnder de senaste decennierna har temperaturen i atmosfären ökat. En sannolik effekt av detta är en förändring av förekomst och styrka för de utomtropiska cyklonerna. Deras uppträdande spelar en betydande roll för väder och klimat över de områden där de förekommer, därför är det relevant att undersöka om samvariationer för dem existerar med till exempel snöförhållanden och temperaturer. För att utforska detta har lågtryck över norra Atlanten och Europa identifierats ur återanalysdata (ERA-40) under månaderna oktober-mars för åren 1960-1999.Denna studie visar på en signifikant ökning av lågtrycksförekomst norr om 60°N och ett signifikant avtagande söder om 60°N. För lågtryckens styrka påvisas en signifikant positiv trend för båda dessa områden.

Utvärdering av Hultdins prototyp för portabel bro (drivningsbro) :

Stronger demand has been put on forestry to show environmental considerations during harvesting. This is especially for crossings of brooks with sensitive elements and great care should be observed when they are to be crossed during harvesting by logging machines. For that reason Hultdins has constructed a portable bridge that can be used for those occasions. The bridge has been developed in accordance with wishes from SCA forest, since they have a great deal of brooks in their forests and in private forests from where they buy part of their wood supply. The aim for this report is to investigate if this portable bridge can be of interest for the forestry market. The research has been made at SCA skog in Medelpad and Norrskog in Medelpad.

Utveckling och tillämpning av en GIS-baserad hydrologisk modell

A distributed hydrological rainfall-runoff model has been developed using a GIS integrated with a dynamic programming module (PCRaster). The model has been developed within the framework of the EU-project TWINBAS at IVL Swedish Environmental Research Institute, and is intended for use in WATSHMAN ? a tool for watershed management developed at IVL. The model simulates runoff from a catchment based on daily mean values of temperature and precipitation. The GIS input data consist of maps with soil type, land-use, lakes, rivers and a digital elevation model.

Identifiering av fosfatfosfors käll- och flödesfördelning i ett litet jordbruksområde

Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large quantities to an intensification of growth. Phosphate (PO4) is the fraction of phosphorus that can easiest be taken up by plants and thus have the greatest impact on eutrophication. Increased plant growth in lakes and unfavorable conditions for aquatic animals are two examples of negative consequences. A significant portion of the increased nutrient supply to nearby water can be derived to phosphate leaching from agricultural areas, where private sewers and agriculture is two main sources.

Livet mellan husen : ett utvecklingsförslag för Disagården

The open air museum of Disagården is situated in the Old Uppsala parish, Uppsala municipality, are projected to portray a double row village, before the land enclosure, on the Uppsala plain during the 1860s and 1870s. Disagården operates under the County Museum of Uppland and serves as an exhibit of Uppland's farming culture during the late 19th century. However, an open-air museum is a complex institution where many interests are linked together. Disagården aims to simultaneously portray an historical environment while offering broad public appeal. The Disagården open air museum was inaugurated in 1931 and consists of relocated buildings that together form three farm complexes "Gränbygården", "Skuttungegården" and "Bärbygården". The thesis explores how the close surroundings of a typical farm in Uppland looked during the 1860s and 1870s. This historical depiction has then been applied to Disagården in a development suggestion creating a foundation from which Disagården can structure the close cultivation of the different farms. The basis of the development program has primarily been compiled through archival and literary studies but also through on-site visits and interviews. How did the concept of open air museums start and what were the ideas behind the concept? Which external influences affected the situating of cultivations and buildings? Which crops and species were present on the farms in Uppland during the specified time period? What was the relation of the different structures to each other? Which organizations had influences on the farmer's household of the Uppland plain? The thesis attempts to clarify the answers to these questions. The influences affecting on the farmer's household in Uppland were probably numerous.

Utnyttjandet av ligghallar hos dikor och kvigor av köttras under vintern :

Cattle used for meat production can be held outside all year round and due to the legislation they should have access to shelters or other buildings for protection against the elements giving them a dry and clean bedding. There are different opinions concerning their need of protection and the question about necessity of shelters for cattle is of current interest due to a less profitable economy in meat production and the investment costs for shelters. The aim of this study was to acquire more knowledge about the natural behaviour of cattle concerning their use of shelters. The basis of the study was a series of questions regarding when animals choose to stay in shelters, if shelters were used less when they had access to protecting vegetation, how temperature and weather conditions affected the use of shelters and the influence of distance between shelter and feed. Behavioural studies was conducted at five different farms where six groups of suckler cows and heifers of following breeds and crossbreeds were observed; Aberdeen Angus, Charolais, Hereford, Scottish Highland Cattle, Simmental and the Swedish breeds SKB and SRB.

Utvärdering av automatiska snödjupsmätningar med en SR50A Sonic Ranging Sensor

I Sverige utförs dagligen observationer av snöns djup och utbredning under snösäsongen.Observationerna används till exempel för att årsvis avgöra maximalt snödjup, snötäckets första ochsista dag samt antal dygn med snötäcke på olika platser. Traditionellt utförs snödjupsmätningarmanuellt med en enkel mätpinne, men med ny teknik kommer nya möjligheter. Med enultraljudssnömätare kan automatiserade snödjupsmätningar utföras med bättre upplösning i bådetiden och rummet vilket därmed ger bättre uppfattning av snöns tillväxt, hopsjunkning samtsmältning och innebär att alla signifikanta förändringar i snötäcket garanterat kommer observeras.I denna utvärdering har en jämförelse gjorts av manuella och automatiska snödjupsmätningarutförda parallellt på samma plats men med olika frekvens. Instrumentet som utvärderats är enSR50A Sonic Ranging Sensor uppmonterad vid Institutionen för geovetenskapers mätstation vidUppsala universitet. Vid mätstationen görs även manuella snödjupsmätningar en gång per dag.

Möjligheter att öka effektiviteten och det ekonomiska utfallet av barkhanteringen vid Seskarö sågverk :

The sludgebark and to a certain extent the bark were until a decade ago waste products without any economic value that were thrown away. A number of environmental laws and increcing energy prices have improved the prerequisites for increasing the use of these materials. At Seskarö sawmill they burn the sludgebark and a great deal of the bark in the sawmill furnace. The sludgebark has a number of disadvantages compared to bark during burning. The sludgebark is often wet which means the energy net from burning often gets low.

Isbjörnars (Ursus maritimus) interaktioner och hägnutnyttjande på Orsa björnpark

SAMMANFATTNINGIsbjörnen är mycket populär hos djurparksbesökare och en viktig symbol för klimathotet, trots detta finns fortfarande många frågetecken kring hur vi ger isbjörnar i djurparker hög välfärd. I litteraturen har vi länge talat om isbjörnar som solitära djur men trots detta låter vi dem ofta dela hägn med andra isbjörnar på djurparker. Det har observerats positiva effekter av grupphållning av isbjörnar, bland annat sänkt förekomst av stereotypa beteenden, men vi måste vidare utreda vilken påverkan det har på deras välfärd. Ytterligare problem för isbjörnar på djurparker är stereotypt vankande som har observerats hos flertalet karnivorer som i det vilda rör sig över stora områden eller hemytor. Syftet med denna studie var att titta på hur isbjörnarna på Orsa björnpark utnyttjar sitt hägn, vilka beteenden som kan observeras samt hur stor del av observationerna de spenderar tillsammans.

I Idolvinstens konfetti och kamerablixtrar: Idol-Agnes vs Idol-Markus: en kritisk diskursanalys av hur en kvinnlig respektive manlig vinnare representeras i bevakningen av Idol 2005 och 2006

Avsikten med den här uppsatsen har varit att undersöka hur könsstereotyper skapas genom att titta på hur kvällstidningarna konstruerar och reproducerar kön/genus när de representerar en kvinnlig respektive manlig Idol-vinnare och vilken betydelse det kan få för meningsskapande processer. Jag har tittat på två kvällstidningars artiklar dagen efter vinsten för Idol-Agnes 2005 och Idol-Markus 2006 och gjort en kritisk diskursanalys på artiklar, bilder och Idol-postrar för att undersöka vilka bakomliggande diskurser som blir synliga i hur tidningarna väljer att representera en kvinnlig respektive manlig vinnare. Till min hjälp har jag haft Judith Butlers teori om genus som en performativ akt och den heterosexuella matrisen, Stuart Halls tankar om representation och stereotyper, och van Zoonens feministiska mediestudier och tankar kring manliga och kvinnliga blickar. För att förklara vilka rutiner och normer som styr en medieproduktion av en text har jag använt mig utav Atheide och Snow´s medielogikbegrepp. Jag har gjort en kvalitativ analys utifrån Norman Faircloughs kritiska diskursanalys för att komma samhällets diskurser på spåren.

Främlingen i snön : Analys av texterna på Kate Bushs album 50 words for snow

Syftet med den här uppsatsen har dels varit att undersöka Kärlek i Europa utifrån frågan om kvinnligt medborgarskap förstått som en normerande livslinje. De karaktärer som Birgitta bebodde världen med i Stockholm har studerats som exempel på hur det kvinnliga medborgarskapets livslinje etableras som den väg Birgitta förväntas vandra.Detta sker dels genom modern, som värderar det som viktigt att ligga i linje, och som inskärper äktenskapets betydelse för Birgitta och strävar efter att göra henne familjär med övre medelklassmiljöer.Även morbrodern, som Birgitta har en hemlig sexuell relation med, blir ett exempel på en medborgare i linje. Han är en patriarkal familjefar, vars familj blir den bild av äktenskap och familjeliv ? de två viktigaste punkterna på den kvinnliga medborgarens livslinje ? som Birgitta förhåller sig till. Att familjelivet framstår som förljuget och regisserat en den manliga blicken gör att detta inte framstår som eftersträvansvärda framtidsscenarier för Birgitta.För både modern och morbrodern innebär detta att befinna sig i linje dock att dölja hemligheter.
