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.

This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.

A study was made on four environmental ponds in Sölvesborgs municipality. The reason forthis was to see if the ponds had fulfilled some of the questions that was mentioned in theproject ?Rädda Hanöbukten?. The questions were as following; do the environmental pondsdecrease the leakage of nitrogen and phosphorus into Hanöbukten, do the ponds decrease theuse of groundwater in Sölvesborgs Municipality and are there any restrictions on what thewater in the ponds is allowed to be used for. In order to answer these questions aquestionnaire was made and interviews were held.

This study examined the psychological processes of autonomic arousal and distress, erroneous beliefs about sleep, worry about sleep, selective attention and monitoring and safety behaviours related to sleep, on the subject of daytime impairments associated with insomnia. The psychological processes were evaluated against as follows: sleep measures, anxiety, depression, medical disease and the use of medications. The measure daytime impairments complied with the established research diagnostic criteria. A correlation analysis indicated that psychological process, anxiety, depression and one of the sleep measures are associated with daytime impairments. The results of a multiple regression analysis proved that only erroneous beliefs about sleep, worry about sleep and safety behaviours related to sleep are linked to daytime impairments associated with insomnia.

An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.

 The purpose of my study is to illumine the aesthetic learning process significant in the preschool. Focus has been on allowing educators in different preschools to answer questions valid the use of aesthetic learning processes. I chose to do my study using an opinion poll and a literature review. The result shows that the preschools use aesthetic learning processes and according to the educator?s aesthetic learning process is a very important tool for education in the preschool.  The notable in this study is that the educators have different views of what aesthetic means. The first view is that you only work with aesthetic subjects.

ABSTRACTThe aim of this study is to look into how ex-offenders experience that stigmatization and labeling- processes might affect their possibilities to create an integrated and adapted life in society. It is also of interest to study how and if the interviewees experience their self-image to be affected by these processes. Our research-questions are:-          How do ex-offender males experience stigmatization and labeling-processes to impact their possibilities when trying to re-integrate into society?-          Do ex-offender males experience their self-image being affected by stigmatization and labeling-processes? If so, how are they affected? In order to achieve this we interviewed members of the organization KRIS in Örebro, where we selected males over 23 years of age with a prior prison sentence. The study is based on the labeling-theory of Howard Becker as well as the stigma-theory by Erving Goffman.In the conclusions derived from the results we found that the interviewees experience a more distinct and obvious stigmatization and labeling from authorities such as the police and the legal system, than that from other people in society.

Lotsbroverket is the largest wastewater treatment plant on the Aland Islands and it isdesigned for handling wastewater from approximately 30 000 persons. In 2011,Lotsbroverket produced about 2800 m3 of dewatered sludge. The sewage sludge that isproduced is transported to a contractor where it is processed to eventually be used e.g.in the construction of green space. This study aims to investigate available applicationoptions in terms of the sewage sludge that is produced in Lotsbroverket. The main aimis to study the feasibility of using the produced sewage sludge as a fertilizer in theagriculture of the Aland Islands.The sludge already fulfills limit values for heavy metals in accordance with the Act"The Aland Government´s directive on the use of sewage sludge in agriculture." Inorder to clarify the sludge content of pharmaceutical and organic substances it isrequired that the substances are identified and a risk assessment is performed.

Eutrophication of the Baltic Sea and Swedish lakes remains a major problem despite many years of effort to reduce the emissions of nutrients. One major source is waste water systems, especially private sewage systems. These sewages accounts for a very large share of nutrients per capita in comparison with citizens connected to larger sewage treatment plants. Norrtälje community has the greatest number of private sewage systems in Sweden. Discharges of nutrients, especially phosphorus, to the Baltic Sea from these sewage systems are significant.

The aim of this study was to investigate preschool teacher?s perceptions about the curriculum goal concerning simple chemical processes. The result was based on narratives received by a qualitative study and semi-structured interviews of six preschool teachers. The results of the study showed that preschool teachers perceive that they actually are working in a relatively small scale with simple chemical processes and they do not really know what simple chemical processes are, and do not feel very familiar with the subject. Water, dough, mud, paint and baking were the most common activities that were used when working towards the curricular goal. However, it was never explained to the children that it was simple chemical processes they were working with during the activities, neither was it discussed among colleagues because of the uncertainty about the concept.

This paper examines the opportunities and challenges of integrating conservation practice and the circular economy into practical planning processes. In recent years, the discussion of circular economy and its relevance in the sustainability debate has intensified. According to the Swedish Environmental Protection Agency, the transition to a circular economy is crucial to achieving the national and international environmental and climate goals as well as the global goals in Agenda 2030. Parallel to this, there is a long established heritage discourse that emphasizes the importance of preserving buildings and cultural environments as part of our cultural heritage. These two discourses have common goals, but they differ in how they present their respective arguments.

The existence for companies today consists of constant challenges with customers that want more individual products with high quality as quickly as possible. For a company to be able to have a short delivery time, it must also have a short production time. This makes streamlining and improvement of processes a big part of a company?s workThis thesis has been carried out together with the company Lasermax Roll Systems AB, a world-leading manufacturer of feeding, finishing and monitoring systems for high-speed digital printers. They manufacture their products according to the assembling for costumer order principle.The purpose with this thesis is to map and analyze, the assembling process and the test process at Lasermax Roll Systems AB.

The amount of various phosphorus (P) fractions in the sediment and the relationship between the amount of P and sediment particle size were investigated in a constructed wetland southwest of Linköping. Furthermore, the possible correlation between clay content in the sediment and distance from the inlet was investigated. Sediment samples were collected along three transects from the inlet to the outlet, with six samples in each transect. In order to measure the soluble P, an NH4Cl extraction was done. This was also analysed for total soluble P after oxidation with peroxodisulphate.

The eutrophication of lakes and seas with the algal bloom and deficiency inoxygen that follow, has been given priority by the Swedish government as oneof 16 environmental objectives. The purpose of this project was to develop a toolbased on a simple model, limited amount of data and geographic informationsystem (GIS) to identify areas with risk for phosphorus losses due to surfacerunoff. This tool can act as a decision support to decide where appropriatemeasures should be applied with the aim of reducing phosphorus losses and bythat the eutrophication.The method that has been used is a combination of two models, one calculatingthe potential erosion while the other one identifies areas of erosion (net erosion)or deposition. This ability is of great importance because potential erosionshould be calculated on areas with net erosion. Areas with high potential erosionhave an increased risk for phosphorus losses due to surface runoff.The potential erosion was calculated based on factors which describe how topography(LS), land use (C), soil type (K) and precipitation (R) effect the erosion.All of them have been modified to a greater or lesser extent.
