Värdering av föroreningsrisk - Ett förslag till angreppssätt för värdering av föroreningsrisk till följd av emission från en vägkonstruktion

When constructing a road the risk of emission of substances from the used materials to the surrounding environment has to be evaluated. The aim of this study is to present a proposal for how to evaluate the risk of contamination as a result of emission from the materials in a road construction. The study is based on literature studies, an inventory and a questionnaire that examines how experts in governmental agencies, industries and universities evaluate the risk of contamination. The inventory indicates that guidelines for evaluating the risk of emission from secondary materials in a road construction do not exist. The conclusions from the questionnaire are: that there is no common way to evaluate the risk of contamination as a result of emission from materials in the road construction, there is no uniform interpretation of the terms "minor" and "significant" risk of contamination and that the evaluation is subjective.

Varför överlåter medlemsstaterna makt åt EU? : En fallstudie om utvecklandet av en gemensam asyl- och flyktingpolitik inom EU.

The aim of this study is to explain the paradox of the memberstates willingness to surrender power of important issues such as asylum and refugee policy and therefore partly abandon its sovereignty. We also discuss the relation between internationalization, regionalization and globalization since these processes form the context in which our research problem is found. A case study is used as a method in this paper.In our quest for answers we use a theory of internationalization that we place in its context by primarily discussing the relation between globalization and regionalization. The theory is used as an explanatory force and to give it a concrete form we operationalised its three processes; internationalization of problems, internationalization of the societies and internationalization of the descisionmaking.The result of the case study shows that the increase in asylumseekers leads to a higher risk of negative competition wich give rise to the memberstates need to coordinate their politics.We found that when societies and problems are being internationalized, the state finds it difficult to resolve problems on their own and this leads to the internationalization of the dedescisionmaking. The internationalization of the decision-making process is therefore natural, which in this case means the decisions are taken by the EU rather than by the member states..

Den vägda nyttjandeperioden och dess effekter på utvalda finansiella nyckeltal: En studie av bostadsrättsföreningars avskrivningstider på byggnader

Housing cooperatives in Sweden practice very long depreciation times for their buildings and assets, subsequently depreciation costs are very low. This study aims at addressing issues relating to potential upward revisions of these costs and the revenue levels needed by housing cooperatives to address these changes, while also providing a detailed summary of some chosen financial ratios under different circumstances. This study's results are based upon recent (2015) market data within the Stockholm region, collected through a manual process and analyzed quantitatively. On average, housing cooperatives EBIT do not cover their financial costs and have low profit margins. The average depreciation time is considerably above what a technical evaluation by other sources may state.

Grönområde kontra bebyggelse : grönområdenas förändring i Älta, Nacka kommun

This essay shows how natural areas in Älta, a part of Nacka municipality southeast from Stockholm, been changed quantitatively and qualitative as a result of the increased housing construction in the area. Three issues are discussed. Namely: how has Ältas green areas been changed in sizes and quality in line with the settlement's expansion, what is the reason or the reasons to building of different types of accommodations, what has been and is the operators in connection with building of the different types of accommodations?The essay shows that the green areas has been decreased with over 2 km from 1901 to 2000 and in addition to these areas of approximately 1,1km been converted to a planned green structure. Älta has during the years gone through four eras of building types an era of small family houses ? an era of building one million houses on a national scale ? an era of terrace houses ? an era of sporadic building of different housing types (one family houses, pair houses, terrace houses and small blocks of flats).

Förslag till kväverening i Forsåsystemet genom våtmarksetablering

The last hundred years humans have drastically changed the amount of available nitrogen in nature. Today human activities release twice as much available nitrogen as all natural processes are doing together. We also have degraded nature´s possibilities to take care of nitrogen through the draining of wetlands and straightening of rivers. In order to regain the potential of nitrogen retention in the water systems there now requires a reshape of the landscape we live in. A planned expansion of the mining activities in Garpenberg, Dalarna, would double the content of nitrogen in the waters below the mine.

Svenskdidaktik i (o)jämlikhetens landskap : en studie om språkutveckling, rasifiering och klass

Symbolic resources transform in to social power and material resources through the educational system. This entails that all students should have equal access to it.The essay compares Swedish didactics in ?immigrant? and ?white? schools, all situated in socio-economically underprivileged areas, analysing interviews with eight Swedish teachers about their didactics regarding restricted and elaborated language code.Understanding teacher?s work in the class room requires attention to the intersections between race and class, and of both to the distribution of symbolic resources in general.The essay finds that the practice of the? immigrant? school teachers differs from the ?white? school teachers?. The former are active, providing intellectual tools, scaffolding and driving force while the later choose a more passive attitude, letting students decide for themselves what to do and what goals to reach. Consequently ?white? schools allow the reproduction of unequal distribution of symbolic resources while practice in immigrant schools aim to compensate for disadvantages.Practice seems to win legitimacy by different sets of conceptualisations.

Naturens lockelse : en studie av dubbelhet i Karin Broos bildvärld

The aim of   the study has been to examine the duality that I seemed to find in Karin   Broos works, primarily on the basis of her renditions of nature. The   objective is to study the duality on various plans and to examine which   traces of Intertextuality that may exist.In the study of the duality   I have taken note of how nature is presented in terms of style and form, as   well as that I have seeked cultural references pictorial and symbolic. I have   also examined the images with reference to Intertextuality. The following   questions has been applied during the work:  How is nature produced in the paintings?  What place occupies nature in relation to the people, in the works?  What is being communicated by nature's participation in the works?As a method, and as a   tool for analysis and interpretation of selected works, I have chosen to use   Panofskys iconological interpretative method. As a guide to seek relations of   intertextuality the theories of  Julia   Kristeva has been useful, which  includes thoughts  that new images are created or re-created   in relation to other images all the time and in new contexts.As a result of the   study I have found some kind of expression of balance, though it did not   seemed to look that way from the beginning.

Arkeologi och den senmedeltida ödeläggelsen

This essay discusses the width of the late medieval desertion of farms in Sweden from an archaeological perspective. The object of the essay is to investigate if archaeological investigations and research during the last 10-15 years have changed the view of the late medieval desertion in relation to the Scandinavian research project on deserted farms and villages.The essay also deals with questions on causes to the desertion and when desertion occurred. An ambition of the essay is also to give a general picture of archaeological investigations during the last 10-15 years considering the late medieval desertion. The analyses-material consists mainly of reports from archaeological investigations.Most of the investigations analysed in this essay are investigations of single farms. Because of this it is natural these investigations do not say much about the width of the desertion.

En undersökning åt IKEA om ungdomars syn på inredning och design

The purpose is to improve IKEA´s understanding of how their target group of 12 to 18 years old boys and girls thinks when they visit the showrooms in the department stores. What make them enter the showrooms? Is it the colours, the furniture or the whole concept? How are they inspired to furnish their own room? Do they get ideas from the showrooms or are they looking for a specific furniture? These types of questions have increased young people´s interest for design and decoration over the last decade. It transpires with help from an article written by Vittorio Girotto and Michel Gonzalez how children are influenced in an early age by their own temperament and their natural surroundings. Children reasons and acts according to what they believe adults would have done in a similar situation.The methods that have been used during this project are interviews, surveys, observations, hypothetical persona, persona and ABL (IKEA´s own method).

Bosättning, agrarkris och fäbodväsende : vegetations- och markanvändningshistoria i Läde, Dalarna

By using pollen analysis, 14C-dating and historical sources, I studied the history of vegetation and land use at an abandoned forest settlement near the Lade summer farms in the parish of Mora, Dalama. The aim of this paper is to investigate the agricultural establishment and development, the effects of this on forest vegetation, and the origin and development of summer farming. The analysis of pollen in a peat core revealed that a settlement was established at Lade around 1000 AD. Cereal cultivation, hay-making on the mire and extensive forest grazing were intro-duced as a complete agricultural system. Pollen analysis and the presence of ancient fields suggests that cultivation took place on permanent fields. Barley was the main crop, but rye and hops/hemp were also grown at the settlement.

Att läsa eller att läsa

Syftet med undersökningen var att klargöra hur lärare arbetar med skönlitteratur i undervisningen. Jag har utgått från tidigare teorier om hur skönlitteratur kan användas i undervisningen, både genom läsning och genom samtal. Det är en survey undersökning baserad på enkäter och intervjuer från ett antal lärare verksamma på samma skola. Frågorna fokuserade på varför lärarna använde sig av skönlitteratur, hur de valde böcker och om och hur de sedan samtalade om böckerna de läst. Resultatet visade att både skönlitteraturen och samtalen var naturliga inslag i undervisningen, men de var inte alltid genomtänkta eller byggda på en tydlig struktur.

Att vänta barn : litteratur för gravida från 1943 till 1981

In our time we can easily get information about pregnancy from books and magazines of thesubject. Mothers to be can also publish their own diaries at the Internet, so anyone can readabout their personal experience of being pregnant. All this information gives pregnant womenideas of what they can expect to experience during the pregnancy. This made me think aboutwhat kind of image, women in the past, did get from literature that described pregnancy.The purpose of this study was to examine how pregnancy and pregnant women has beendescribed in literature during the period 1940-1980. I have used various kinds of books aboutpregnancy released in: 1943, 1948, 1955, 1965,1969,1972, 1977, 1981.

Interspecies embryo transfer in South American camelids : a field study

The aim of this study was to investigate the possibility of performing inter-species embryo transfer under actual field conditions in the natural habitat of South American camelids. In this study embryos from llamas were transferred to alpaca recipients. In a parallel study alpaca embryos were transferred to llama recipients. All animals used were free of uterine and ovarian abnormalities detectable by rectal palpation and /or ultrasound examination. Embryos were harvested twice after single ovulation in 10 mated female llamas and non-surgically transferred to synchronized alpaca recipients.

Uran i dricksvatten : litteraturstudie om reningsmetoder samt pilotförsök med jonbytesteknik

Uranium (U) is a naturally occurring component in bedrock and under the "right" conditions it can dissolve and move into the ground water. Since many people in Sweden depend on drilled wells as their main drinking water supply, they may be exposed to the uranium in the water. Radioactive radiation is not the major concern associated with naturally occurring uranium. It is rather the chemical properties of uranium that make it a potential danger to human health. Uranium is proven to have toxic effects with respect to the functioning of the kidneys.

Barn på museum : En multimodal analys av Naturhistoriska riksmuseets och Nordiska museets riktning mot barn
