Discharge of inadequately treated waste water containing nutrients such as phosphorus and nitrogen as well as organic matter and bacteria is associated with a risk of eutrophication and contamination. The Swedish government has decided upon several Environmental Quality Objectives aiming to reduce the emissions of nutrients to water bodies.In Sweden, there are between 675 000 to 1 000 000 on-site sewage systems. Recent studies have shown that the function of small sewage treatment plants is in many cases insufficient. To prevent this regular service and supervision by a professional is needed. The focus of this study are small sewage treatment plants which use a technique where mechanical, chemical and/or biological reduction of pollutants is being used in the same facility to reduce nutrients in household wastewater.The aim of the study is to investigate how different municipalities ensure that small sewage treatment plants fulfill the requirements and reduce pollutants as efficient as the manufacturers claim.
?Det verkar som man helst vill vara någon som är blond, smal och glad? : En komparativ studie av två olika chefredaktörers versioner av Veckorevyn
The purpose of this study is to compare the contents, editorials and front covers of Sweden?s oldest girl?s magazine Veckorevyn during two different years, in which the magazine had two very different chief editors.In the year 2000, Emma Hamberg got the job as editor-in-chief for Veckorevyn, with a vision of changing the way the magazine represented young females. She wanted to add a more feminist viewpoint to the magazine, since she felt that Veckorevyn didn?t live up to its claim of being ?a girl?s best friend?. Six years later, the famous Swedish fashion editor Ebba von Sydow became editor-in-chief for Veckorevyn, with the intention of making the magazine better, smarter and more fun for young girls.
Miljömål 17: Hållbar konsumtion : Ett försök att integrera den svenska konsumtionens globala miljöpåverkan med miljömålssystemet
Environmental objective 17: Sustainable consumption - An attempt to integrate the global impact of the Swedish consumption with the environmental objectives system The aim of this report was to integrate the global impact of the Swedish consumption withthe environmental objectives system through presenting a suggestion for a seventeenth environmental objective ? Sustainable consumption. How the Swedish consumption pressures the global environment and methods to measure the affects was investigated. The pressure was divided into five main fields: climate, air, water, land and chemicals. The impacton humans and the biodiversity was also discussed, as well as differences between how men and women affect the environment and get affected when the environment changes.
Grundvattenmodellering i Badelundaåsen
Over an extended period of time there have been plans to establish a shared facility in Lennheden to extract groundwater from the Badelunda esker to provide drinking water for the cities of Borlänge and Falun. The city of Falun is dissatisfied with the quality of its drinking water and the city of Borlänge is concerned about the risk of contamination of its existing groundwater supply at its current location. To provide a basis for a decision on this issue, the company Midvatten AB has been commissioned to perform hydrogeological investigations in the area of Lennheden.The purpose of this thesis is to design a functional groundwater model of the area between Lennheden, place of planned extraction, and Övre Tjärna, place of existing extraction, to get a better understanding of the groundwater situation in the area. A groundwater model enables simulations of different scenarios in risk assessment and contaminant transport. The aim of the thesis is that the model can be used as an aid in Midvatten?s investigations in Lennheden and that it also can be used in future projects in the area.The model has been made in Processing Modflow 5.3 and encompasses an area of 19,5 × 11 km along the Badelunda esker and the river Dalälven between Djurmo and Frostbrunnsdalen.
Pre-spawning habitat selection of subarctic brown trout (Salmo trutta L.) in the river Vindelälven, Sweden
Habitat selection of migratory brown trout at the upper reaches of River Vindelälven, wasstudied in September during the pre-spawning period. The fish migrate from down- orupriver lakes for spawning in the river and data was collected by habitat mapping andradio-telemetry. Habitat selection of fish was analysed with preference curves andstatistical modelling, using the physical variables; depth, stream velocity and streambedsubstrate. Preference curves were derived by comparing fish habitat use with their nearbyavailable environment while the statistical modelling aimed to answer three main questions.1) Do the trout have a specific preference of depth, water velocity and streambed substrate?2) Is there any difference in habitat selection between sexes? 3) Is there a shift in habitatselection over time? The preference curves indicated that trout favored water depths of 1-2m, velocity compositions characterized as glides (c.
Fisk- och fågelpredations påverkan på den bentiska makroevertebratfaunans sammansättning under tidig vår i Tåkern
Predation is one of many factors that form the structure of the macroinvertebrate community in lakes, wetlands and watercourses. Earlier studies lack an examination concerning how fish- and waterfowl predation affect macroinvertebrates during shorter periods in the spring. I performed an exclosure study in the shallow eutrophic Lake Tåkern which is located in the western part of Östergötland County, Sweden. The experiment was performed during a three week period (1-21 April 2012) when the water temperature was low and the density of migrating diving ducks was high. The experimental cages used included three out of four different treatments; general predation (open cages), bird exclusion (net with mesh size 90*45mm) and no predation (net with mesh size 1*1mm).
Alla är vi lika men ändå olika. Ett mönsterprojekt inspirerat av kroppen
Sweden has a great tradition of pattern in both wallpapers and fabric, where colours and shape matters a lot for the customer. I have through my examination project tried to expand the views and find new alternatives and shapes for the obvious pattern traditions. I have therefore worked with what could be on the verge of attractive or repelling. To create a curiosity of what is considered to be commercial. From the prospective of the body organs I have created physical patterns for fabric and wallpapers.
Stadsparken i Trelleborg - en resa i historien
This thesis was performed as assignment from Fazer Food Services. The aim was to survey which food additives that were present in the products in the quotation list of one of their suppliers to the Education and Nursing segment. The aim also was to perform a theoretical analysis of these food additives and to make recommendations which food additives are acceptable and which should be excluded from the products in the future. The recommendations are not published in this report, for more information Fazer Food Services can be contacted. Food additives which have already been approved are regarded as safe according to the safety evaluation methods available at the time of approval.
Nu ska jag berätta en saga : En studie om hur berättarteknik kan främja läsvärde och läsbarhet i ett informationsmaterial
In this study I have examined how narrative techniques can be used to promote the reading value and readability in information. My focus has been on the communication-agency Mandoly?s information-brochure which function is to inform other companies about their own potential for development in collaboration with Mandoly. The purpose with this study is to examine how it is possible to increase the reading value in order to engage the target group. In my study I have used four methods: analysis of Mandoly?s old information-brochure, literature studies, a qualitative interview, and an user test.
Soil carbon in small-holder plantain farms, Uganda : a comparison between agroforestry and non-agroforestry
Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land
management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC)
compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on
crops during drought.
The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to
study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.
Markanvädnings och markvård på småskaliga farmer i Bungomadistriktet, Western Province, Kenya
In Northen Bungoma, Western province ? Kenya, the Vi-Agroforestry Project (VI-AFP) has introduced a new project that covers 7000 households. To succeed with the project, a water resources protection project, agroforestry methods will be implemented to secure the water quality of the area. In this thesis a foundation is laid for future follow-up studies of land cover and land use of this area. To carry out this study an existing method from a cooperation between VIAFP and Dalarnas University (HDa) has been implemented.
Renovering av flerbostadshus - en studie om energieffektivisering och lönsamhet
In today?s society a large focus is put on energy systems and how our energy systems are built up. In order to make sure that we in the future still can enjoy the living standards that we are used to today, Sweden and EU have made a number of decisions on making our energy system more energy efficient and consequently reduce the usage of energy resources. By 2020 the European Union should have reduced its energy consumption by 20 % compared to 1990?s level, and by 2050, 50%.

Jeanine Basingers bok The World War II Combat Film presenterar en annars väldigt oupmärksammad genre, den amerikanska Andra Världskrigs-stridsfilmen. Utifrån den mall som Basinger beskriver i boken har jag här diskuterat och analyserat hur Saving Private Ryan håller sig till mallen som skapats av tidigare stridsfilmer. Mallen består i korthet av en mängd element som används genomgående i genren; såsom gruppen, hjälten, målet och fienden. Dessa element förekommer från den första andra världskrigs-stridsfilmen Bataan från 1943 och har konsoliderats och utvecklats sedan dess. Slutsatsen blir att även om SPR blivit känd som en nydanande och orginell film så är håller den sig nästan slaviskt till mallen, det enda som möjligt kan skilja den lite från andra filmer i genren är det ursprungliga målet, det är inte vanligt att ha ett såpass politiskt inkorrekt mål som att rädda en enda man..

Synoptisk provtagning i vattendrag med eutrofieringsproblem : En studie för att identifiera områden för prioritering av åtgärder
In Halland, agriculture is the major source of eutrophication of water. In the study, synoptic sampling were performed in the three watercourses Nyrebäcken, Skintan and Vinån all located in the county of Halland. Sampling occurred during the period February to May on three occasions with different flow rates: high, low and base flow. Samples were taken in the mainstream and tributaries with intention to show how big the impact of eutrophication it is in the water and to assess the impact of the tributariesThe results show that all watercourses are affected by eutrophication. Nyrebäcken has the highest concentrations of nitrogen and phosphorus in the mainstream, then Skintan and last Vinån.
