Bättre enskilda avlopp i Sigtuna kommun : möjligheter för bebyggelse i Odensala socken
There are around 855 000 on-site sewage systems in Sweden and some 1 800 of these are located in the municipality of Sigtuna. The Sigtuna local authority has set the goal that all sewage systems with insufficient function should be improved before the end of year 2010.
A malfunctioning on-site sewage system may cause three main problems: spreading of diseases, discharge of eutrophicating compounds and wastage of resources. The municipality strives to reduce these problems already at the stage of granting permits for installation of on site sanitation systems. The municipality has recently adopted new guidelines, which demands certain minimum reductions for different compounds. The guidelines also state that it is preferred that neighboring house-owners cooperate in jointly built and operated sewage systems and that the system should be able to recycle plant nutrients.
Hästars aktivitet och liggtid på madrasserade gummimattor i box
Sleep is essential for all mammals and they all have different sleep patterns. Wild horses normally spend 2-8.5% of a 24-hour period in recumbent position while stabled horses lie down 11-20%. To fulfil the need of rapid eye movement (REM) sleep the horse must lie down with support against the ground for the head. The lying behavior can be affected by external stimuli such as age, food intake, bedding materials and if the horses feel safe or not. This study investigates the lying behavior of horses on different bedding materials; wood shavings and filled rubber mats (HIT SoftBed®).
Karakterisering av lakvatten genom fraktionering och multivariat modellering
Bakgrunden till föreliggande examensarbete är att lakvatten från upplag med till exempel hushållsavfall och industriavfall kan ha miljöstörande egenskaper. För karakterisering av lakvatten finns inte några fastställda allmänna metoder. På IVL, Institutet för Vatten- och Luftvårdsforskning, pågår ett projekt vars syfte är att utveckla en metodik med vilken lakvatten från avfallsupplag kan karakteriseras. Detta examensarbete utgör en del av karakteriseringen och syftar till att karakterisera lakvatten med hjälp av fraktionering efter partikelstorlek och multivariat modellering. Fraktioneringen grundade sig på en laborativ del baserad på tidigare utförda försök.
"En gåva vi ska vara glada för" : Identitetspolitiska lässtrategier i den svenska receptionen av YAHYA HASSAN
This essay focuses on the reception of Yahya Hassan?s debut YAHYA HASSAN in Swedish media, mainly daily newspapers. Following the work of Magnus Nilsson it analyzes the ?reading strategy of the politics of identity? in ?immigrant literature? and outlines structural racism in the literary scene. By bringing attention to the critics? use of this reading strategy, it is possible to unveil the ?ethnic filter? through which literature by Swedish authors with a ?non-Swedish identity? is being read in contemporary Swedish literary criticism.
Materialavfall som resurs : En studie av hur man samarbetar i en region fo?r ha?llbar utveckling
The concept of sustainable development has been pervasive in recent years and many organizations choose to implement sustainability and adapt their activities accordingly. The purpose of this study have been to explore how a collaboration on the use of waste materials may look to analyze what influences cooperation. A case study has been carried out examining a Swedish state regional project aimed at creating partnerships between actors and utilizing textile waste with the help of design. The study was conducted using qualitative methods and the collection of data has been done through interviews and by examining documents. The results show that there are seven key factors that affect cooperation: expectations, commitment, internal communication, a strong non-profit actor, individual treatment, personal networks and the diversity of actors.
Små barns lärande i skogsmiljö : En kvalitativ studie om hur pedagogerna inom I ur och skur arbetar med de yngsta barnens lärande i skogen
The purpose of the survey was to find out how early childhood teachers work with the curriculum of I Ur och Skur with children between 1-3 years in the forest and how such educators are using the outdoor pedagogy in the forest environment in preschool.In order to answer the study's aim and objectives interviews were performed with six teachers in I Ur och Skur kindergartens.What emerged from this study is that forest excursions are a central part of the curriculum and is seen as their educational place. The teachers are working to create a feeling of security among the youngest children of enjoying the woods and also to raise an interest in the children. Natural materials are used during the forest stay and no other toys or materials.The results reveal that educators work to get the smallest children to use and develop their imagination at play and at the same time they are involved with the children in their discovery of the woods. With the smallest children in kindergarten it involves being on the level of children and as a teacher to have the flexibility to change the forest stay environment if needed..
Akustisk mätning av U-värde
This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions:
? Can U-value theory be combined with acoustic theories?
? Can the coefficient of heat be affirmed trough an acoustic measurement?
The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units.
The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory.
The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.
Biblioteket bokskogen : Perspektiv på bibliotek för barn på sjukhus
The purpose of this study is to focus on library service for children in a hospital, which in turn is seen in relation to a traditional children s library. Four aspects of library work were investigated. These aspects were working methods, partners of co-operation for the libraries, media policy (acquisition, use of the collection and circulation procedures), as well as programme activities for children.The research method was qualitative and comparative in nature, consisting of case studies of two libraries : (1) the library in a children s hospital, known as Bokskogen at Astrid Lindgren s children s hospital in Stockholm and (2) a traditional children s library, the children s department at Eslövs city library. In each library interviews were conducted. The investigation shows that the librarians in the hospital library must be more outreaching and active in order to stimulate children to use library materials.
Bandagering av framtass på hund och katt : en kvalitativ innehållsanalys
The field of veterinary nursing should be based upon research and proven experience. Few studies have been performed within the area of distal limb bandages. Therefore the aim of this study was to examine and describe how to place a distal fore limb bandage based on proven experience.
Data material was collected through four interviews with professional veterinary nurses, and then analyzed using a qualitative content analysis. In the analysis data material was transcribed and then divided into meaningful units that responded to the aim. The meaningful units were then condensed.

Kapitalbindningen anses i dagsläget vara för hög. Därför är det viktigt att ta reda på hur det interna flödet av returstål ser ut, för att på det sättet kunna förbättra lagerstyrningen.
På vilka sätt kan bibliotek vara användarvänliga för människor med dyslexi?
The purpose of this study is to find out how libraries can be user-friendly to people with dyslexia by focusing on how adult dyslectics experience the library. Data were collected through literature and interviews with adult dyslectic students. Two different types of user studies served as a theoretical framework; one was an individual-related study by professor Wilson and the other was a system-related one from professor Buckland. The findings in this study shows that dyslectic library users often experience difficulties when seeking for materials in the library, due to the libraries organisation of material according to the written language. Through technical aid and a more user-friendly organisation of materials it may be easier to find relevant material for dyslectics.
Miljöoptimera avfallsindustrin i Sverige : - återvinn restprodukten gips
One of the most common ways to produce heat and electricity in Europe today is by the incineration of waste or combustion of coal. These materials can be very sulfurous and during combustion sulfur dioxide is produced. This is an environmental and health related toxic substance which is why power plants have strict regulations on removing it from the flue gas. Sulfur dioxide is removed from the flue gas by adding a limestone reagent. The sulfur dioxide reacts with the limestone and the synthetic product obtained is ?Flue Gas Desulfurization gypsum?.
Digitalisering av biblioteksmaterial : En kvalitativ undersökning av åtta biblioteksanställdas attitydertill digitalisering
This study aims to examine the views on digitization of eight respondents, all working at different libraryinstitutions in Sweden, and how their views are reflected in their library's digitization strategies. The poll wasconducted on the basis of Ingrid Mason's theory of information standards, their structure and sociopoliticalnature. The informantion standards are divided into three aspects, curatorial, semantic and technical, and theyaffect selection of, intellectual and physical access to the digitized material, which in the end is what constitutes the digital cultural heritage.The background to the study is that the Swedish library institutions in the current situation lacks a nationalstandard or a common strategy for the digitization of cultural heritage, while it is still implemented digitizationprojects at many library institutions. The method used is qualitative, structured interviews with open-ended questions.The study shows that one of the main motives behind the libraries' digitization projects is to make librarymaterials available in a new way, creating greater opportunities for the users to take advantage of the material.The library users are the ones who mainly control what is digitized, although aspects of preservation ismentioned. Furthermore, it appears that the respondents believe that digitization offers improved capabilities tosearch and learn more about the collections, but the actual work of image capture, the addition of metadata,presentation to users and long-term preservation is very complex.Views on what it is to be digitized, how the material should be selected and provided with metadata and howit should be presented to users is what creates the standards that libraries use when they digitize their materials,and digitization of library materials creates new conditions for new users to access and use library material.This is a two years master?s thesis in Archive, Library and Museum studies..
Ensam är stark!?
I am interested in humans, bodies, movements, directions and how they affect each other. How we move towards each other or away from each other, inside a home or outside. How we relate to each other and to what people say and do. Co-operations between people that occasionally, possibly, do not work; how certain relationships, like certain materials, can have various breaking-points; that materials can be laden with numerous preconceptions, for instance what they should be used for.Beginning from the perspective of a feminist commune, I have explored the concepts of family, belonging, and loneliness. I have interviewed, observed, photographed, and through living in the commune during shorter periods of time, I have taken part in their every-day life.
