Hallsta paper mill uses large amounts of water during the pulp and paper making processes. The wastewater is treated in two separate activated sludge processes referred to as BIO 1 and BIO 2. The main aim is to reduce the organic substance content, measured as COD (Chemical Oxygen Demand) before the wastewater is released into the environment. Since the effluent produced is very rich in organic substances, the addition of nitrogen (N) and phosphorus (P) are necessary to give satisfactory treatment results. Problems with sludge bulking sometimes occur which lead to increased levels of suspended matter and nutrients in the effluent.

On Ericsson Ltd in Borås a wireless communication system called MINI-LINK? is produced. In order to sell their product with the best possible quality guaranty, there is a signal processing circuit called ATLAS implemented in the system. This circuit would eventually be useful in the production and for the repairs of the radio units. Our commission was to examine the possibility for this use.

Eskilstuna Folkhögskola is located in Munktellstaden in Eskilstuna. The school has two separate buildings with entrances that are difficult to find. By having two separate buildings, and to be in an area where there are rules and guidelines for the area's environment, makes it difficult to guide visitors to the school premises.The purpose of my research was to examine how to guide visitors to the school, and how to increase understanding that the school's various buildings are connected.Through practices such as site analysis, interviews, I found that the guidelines are not adapted to the current situation that is established in the district.Through theory and empirical material I have produced a design proposal to facilitate Wayfinding to Eskilstuna Folkhögskola. This is presented as a landmark and a clarification of the schools entrances and signage..

The main purpose with this study is to make the modified parenting visible in relation to the school over time. How have the views of parenting and support, by the pedagogues and the parents, earlier been interpreted and how is it today? The results of the interviews, which were more like an everyday dialogue, were analyzed through a phenomenological effort with a hermeneutist method interpretation. The theory connection has mainly consisted of relevant terms for this study.I have come to the conclusion that parents today feel that they have an extended responsibility when it comes their own children?s knowledge.

Abstract The global average temperature has increased by 0,74°C over the last 100 years. Most probably, the explanation is due to increasing use of fossil fuels and the agricultural expansion of land use. The new life stile of mankind leads to increasing concentrations of greenhouse gases in the atmosphere. Food consumption contributes with approximately a quarter of the total greenhouse gas emission per person and year, why it is an important task to reduce these. The aim of this work is to quantify energy use and greenhouse gas emissions for (Swedish) herbs produced in Swedish greenhouses. The study is based on a LCA (Life Cycle Assessment) and collected data from participating companies producing herbs in pots.

Quality was earlier only an issue for the company?s quality departments but today is the entire organization involved in quality- and improvements work. With the customers in focus, both external and internal, quality and improvement work should be integrated in the daily activities. The management shall state goals and visions together with a policy. Through participation the correct requirements for a successful work are created.With SPC, statistics process control, there is an opportunity to perceive variations in the process and with the correct tools make it stable.

certain building or environment can get a protection as a notable building if it contains certainvalues. These values are established by a certain category of people from the cultural sector.These people use established criterions to define the cultural value of the object. The objects canbe evaluated differently depending on who has done the evaluation. The people who protect thecultural environment and choose which buildings that are to be defining as notable buildingsoften uses a special model to characterise the different cultural values. This model is produced bya man called Axel Unnerbäck.

We have produced a process mapping and from there developed a document management plan for the research service at the Labour Movement Archives and Library (ARAB) in Stockholm, Sweden. The project was conducted during five weeks in the spring of 2011 at ARAB and the resulting classification structure and document plan has been formulated and presented to the staff at a seminar. We found that the institution in some cases were suffering from an inadequate documentation in a number of the identified processes, and also in their records management and archiving. In this additional memorandum follows an analyzing discussion of activity-based document- and archive management, e-archives and process mapping. We have accordingly tried to standardize the process of research services and contribute to a more adequate document management within the institution.

Data retrieved from airborne laser scanning represents a new source of forest data. Today, the technology has matured so that it can function in an operational environment. The aim of this study was to compile areas of application of laserdata in forestry. Moreover to analyze costs and accessibility of laserdata. The goal was to provide private forest owners information to support assessments of possible benefits of laserdata.

Platelets are small fragments, but they are of crucial importance for the coagulation. The risk of spontaneous bleeding increases when the level of platelets falls below a thrombocyte particle concentration threshold value of 50 x 109/L. In those cases a platelet transfusion might be compulsory. Ongoing research tries to improve the quality of the platelets and to increase the safety of the method used. However, we still need to better understand which factors that affect how patients react upon platelet transfusion.

Numerous studies raise the topic of highly educated immigrants whose education and list of qualifications devalue in the context of the Swedish labour market. However, little is known of those with foreign background who enter into higher education in Sweden. Our study attempts to shed some light onto the value of higher education relative to that of a person?s ethnic background. The background material features nine in-depth interviews of foreign background academics, as well as data extracted from an extensive survey study previously carried out at Växjö University. Initially, the quantitative data showed that students with foreign background, including Swedish-born children of immigrants, had not managed to find qualified work upon completion of studies to the same extent as their Swedish background counterparts.

The purpose of this paper is to examine and to analyze the arguments about a possible Swedish law against the veil. I have therefore highlighted how notions about the veil creates and reproduces power-structures and meaning-systems. I structured the arguments in a pro et contra schedule and then analyzed them by using a theoretical framework consisting post-colonial feminism, orientalism, multi-culture and intersectionality together with research produced by Joan Wallach Scott (2010), Pia Karlsson Minganti (2007) and Anne Sofie Roald (2003). The results of the study shows that the people who either argue for or against a veil-law agree that the veil is an oppression of women and that it must be resisted. To be objective in the discussion of the veil seems to be impossible and the women it affects deprived voice.

Every year about 210 000 tones dry weight of sewage sludge is produced in Sweden. Most of the sludge is applied to agricultural land, plantsoil and landfill cover. Sewage sludge contains essential nutrients such as nitrogen and phosphorus. Nitrogen is limiting growth on solid ground in Sweden and can therefore be used as fertilizer to increase productivity. In order that the sludge can be spread to forest land it requires first a conversion of sludge to pellets, to make it more manageable.

The quantity of methane emissions from sheep depend on several factors, for example, the composition of the diet, feed quality, the age of the animals, time of the day and maybe also breed and sex. A comprising literature review was made about which factors that affect the size of emissions. In addition, a questionnaire was sent to two farms, one with a more intensive production system and another with a more extensive system. Inventories of the two farms were made; the rest of the data needed to conduct the study was taken from literature and other sources. Meat produced at the more intensive farm caused emissions of 0.4 kg of methane per kg of bone free meat and the more extensive farm caused emissions of 0.9 kg methane per kg of bone free meat.

If not purified leachate from landfills would cause damages on the environment. At most landfills in Sweden local treatment of leachate is achieved, at the rest the leachate is transported to sewertreatment. While no comprehensive legal provisions for discharge exist in Sweden there is a difference in discharges between the installations for landfill. If no comprehensive legal provisions is produced guidance must improve.Treatment of leachate and self monitoring system at fifteen installations in Sweden has been studied and compared. A study of literature about different treatment solutions has also been performed.
