Laktester för riskbedömning av förorenad mark :
Using leaching test is a way to get a picture of pollutants retention and leaching in a risk assessment on contaminated land. There are several different types of standardised leaching tests today, where the natural leaching processes are speeded up to make it possible to predict the leaching of pollutants. These leaching tests have been developed for waste and there are no specific guidelines on how to judge the results from the tests, when making a risk assessment on contaminated land. This work is an investigation on how to use leaching test in this type of risk assessments. The strengths and weaknesses of the different types of tests are discussed.
Depending on what type of information you want from your leaching test, different types of tests are suitable.
Karlskrona stadsbibliotek 1906-1959 ? En bit av ett biblioteks historia
This master?s thesis will try to describe the beginning and development towards a modern public library of the town library in Karlskrona between 1906 and 1959. The specific years refers to the year the library was established and the year it moved to the new library building in the centre of Karlskrona. The aim of the thesis has been to do this historical description and to look at the course from the perspective of the national policies and development for the Swedish modern public library. The thesis is based mainly on reports of the proceedings of the public library and other biographical documents and literature, which has been found in two local archives.
Webb 2.0-relaterad marknadsföring - Möjligheter och risker med marknadsföring i webb 2.0- relaterade webbtjänster
The purpose of this master?s thesis is to examine how some university students, who are using the libraries extensively, use and experience the public and the university library and what they expect from the two different library types. I also compare their expectations with the different tasks and aims of the two library types. To answer this I have interviewed seven students at the department of history of literature at Göteborg University. I have also studied some literature and research related to this subject, for example user studies about students and libraries and the information behaviour of distance students.
Utvärdering av koldioxidmätaren Vaisala GMP343 samt sambandet mellan grundvattennivå och koldioxidavgång från torvjordar
The research group Soil and Water Management at the department of Soil and Environment at theSwedish University of Agricultural Sciences in Uppsala are studying greenhouse gas emissions fromcultivated peat soils. To measure carbon dioxide emissions from peat soils in the field the researchgroup are now using two portable carbon dioxide meters (Vaisala GMP343). For practical reasons,they plan to acquire a new type of automated field meter. The aim of this study is to evaluate thepresent meters to see how environmental conditions and instrument settings affect the results,which is meant to facilitate the introduction of the new field meter when the meters needs to becompared. As a part of the study the relationship between groundwater level and carbon dioxideemissions from peat soils will be investigated.The evaluation of the two carbon dioxide meters was made by connecting them to one single airtightsystem, with the aim of creating identical measurement environments.
Bättre åtkomst till avverkningstrakter med anpassat marktryck från avverkningsmaskinerna
The global climate-change means increasing mean-temperature and higher precipitation in Sweden, which leads to shorter periods of frozen ground in the forest. At the same time the harvesting machines are getting bigger and more powerful. The forest industry aim at an even wood flow, and the ground damage has to be as low as possible. The two biggest causes for ground-damage is the bearing capacity of the forest ground and the ground-pressure of the harvesting machines. The aim of this study was to find out some rules for the machine choice considering ground pressure, when harvesting on ground with low bearing capacity.A field study, using a Valmet 890.3 forwarder, was carried out where different ground pressures and their effect on the ground were tested on two different types of ground.Additionally, an inventory of damaged harvesting grounds was made.
"Lika enkelt att pröva den där kärleksgrejen" : Svenska mäns erfarenheter av relationer som inletts med sexköp i Thailand En kvalitativ studie
The aim of this study in social work was to investigate, describe and analyze six Swedish men?s description and experiences of relationships with bargirls in Thailand, whom the men initially paid for sexual services. We also aim to find out how these men look upon prostitu-tion, masculinity and gender and we analyze these themes in relation to the men?s description of their relationships. The theoretical approach was social constructivist theories of masculini-ty in combination with gender theory.
Populära bilderböcker och genus: Genusstrukturerna i de mest utlånade bilderböckerna 2007
The purpose of this Master's thesis is to examine if stereotype gender patterns are showing, and how they are showing, in the picture books that have the highest number of loan in Sweden?s three biggest cities. It is also a purpose to show if these gender patterns can be compared to the outlook on gender in the curriculum. The method used is a qualitative text analysis. 13 picture books are analyzed on the basis of Yvonne Hirdman?s theories on gender and Maria Nikolajeva?s theories on children?s literature.
Institutet för språk och folkminnen : En arkivförteckning för teckenspråksmaterial som överlåtits av Sveriges Dövas Riksförbund
This thesis at the Institute for Language and Folklore has as its purpose to lay a foundation for a continuinginventory work. The tasks I have performed during my time there was to create an archival description, anintroduction to the material and a process map showing the process of incoming delivery of documents. The aimwas never to finish the list of work, but to structure the material to get an insight into the material and to theproblems that existed within. The documents are of a very unique nature and require that the archivist is familiarwith and have knowledge of sign language. One of the problems I encountered was how fragmented the materialwas.
Framtagandet av ett företags visuella produktidentitet
Aqeri has since the past year a new profile with name and logotype, which has createda need for an updated visual product identity. The company is a leading developer,producer and distributer of IT products suitable for extreme environments in industry,defense and vehicles. This new profile with the different segments has together with aproduct identity from two companies resulted in that they have no clear designidentity on their products. From this background the aim of this research is todetermine how a development of a design identity is done to implement it to Aqeri.The design identity can be defined as a product?s identity visualized through its formor appearance which defines what the product is.
Lika deltagande eller kompensation : En intervjustudie av hur högstadielärare förhåller sig till elever med dyslexi i undervisning och betygssättning
This essay aims to examine how Swedish compulsory school teachers claims to handle dyslexia while educating and grading, and to what extent they are influenced by others while grading. This was examined through interviews with a phenomenographic approach and the participants were eight grade 9 teachers. The categories of description found in the analysis was then interpreted through researcher Claes Nilhoms dilemma perspective, focusing on the dilemma Equal Participation - Compensation. Regarding education, three main strategies occurred: actions directed towards all students, methods of compensation organized by the school and individualized methods of compensation. The former is closest to Equal Participation, the latter to Compensation and the school organized methods form a middle position somewhat closer to Compensation.
Plan för multifunktionella buffertzoner längs Vramsån på Malörten AB: s jordbruksfastigheter
To create multifunctional buffer strips along a watercourse in an economically sustainable way requires consideration of many different factors. In this plan we have selected pollutant reduction as the main purpose of the buffer strip. We have also strived to achieve minimal income loss due to reduced production, increased biological diversity, good game preservation that leads to higher income from hunting, aesthetical satisfaction and possibility to profit from available subsidies. This is done mainly to make landowners/farmers more interested in creating buffer strips along water courses.
As sand is the dominant type of soil in the area, the water course is less affected by surface runoff compared to if the soil would be clay or some other finer texture. Game preservation and subsidies have therefore been the main factors when establishing the width of the strip, because these require wider buffer strips in some cases.
Lodgepole pine - stability after thinning
SCA has today almost 300 000 hectares of their forest land planted with lodgepole pine(Pinus contorta var. latifolia). Due to initial extensive planting in the 1970ies the area oflodgepole pine forests in the thinning age has grown rapidly from the end of the 1990ies.During the years 1996-2005 first commercial thinning of lodgepole pine at SCA took place.The goal of the hereby presented study was to investigate the growth and stability in thosefirstly-thinned lodgepole pine stands a few years after thinning. Furthermore, the objectivewas to investigate the relationship between stand stability and different stand parameters.Additionally, lodgepole pine stem quality was estimated.The study is mainly based on the data collected during an inventory project carried out atSCA in 2008. Altogether 91 lodgepole pine stands in northern Sweden were measured afterthe first thinning.
Naturlig nedbrytning av klorerade lösningsmedel i grundvatten
Chlorinated solvents are common contaminants in soil and water. Under anaerobic conditions microbes are capable of transforming chlorinated solvents into ethylene which would result in a remediation of the contaminated area. In order to use natural attenuation as a remediation method evidence of continuous degradation is required. Furthermore, the degradation must occur at a sufficient rate and continuous monitoring of the site is needed until the demanded levels are achieved. A field study was performed on the basis of data from a dry-cleaning facility contaminated mainly by perchloroethylene.
Allsidig rörelsekompetens hos barn och ungdomar : En kartläggning av skolelevers funktionella motorik
Gross motor skills among Swedish pupils. An overview of functional motor abilities among Swedish children and adolescents.IntroductionPhysical Education (PE) teachers in Sweden have noticed that pupils are getting worse in their ability to manage gross motor skills and in their aerobic practice. The gross motor skills and coordinative skills are the solid ground for sports and other health activities. If not developing their gross motor skill children tends to avoid taking part in games and sports. The benefits of sports and outdoor activities such as social and health benefits can therefore be missed.
Fodder to ruminants within agroforestry systems in Rwanda - species and management
Rwanda is one of the poorest countries in the world and about 70-80 % of the population lives in rural areas. The land is strongly affected by land erosion which makes it difficult for the agriculture and food production. Agroforestry is a system where tree plantation is combined with livestock- and crop production. The system provides soil fertilization and binds the soil together. Some of the trees used in agroforestry systems are also used as fodder.
