Inre erosion, som är orsaken till 1/3 av alla dammbrott och skador på fyllningsdammar, bildas när det naturliga läckagevattnet genom dammen för med sig eroderat material. Sjunkgropar på dammkrönet bildas då jordmaterial successivt rasar ner där ett jordunderskott utvecklats till följd av erosionen. Då dessa hål på markytan upptäcks, har i regel erosionen pågått länge. Det finns rapporterade skador på fyllningsdammar som föregåtts av grumligt vatten nedströms dammen. Att övervaka grumligheten, även kallad turbiditeten, på läckagevattnet, kan ge en god bild av dammens status beträffande inre erosion.

The sandy beaches of Vänern are threatened by overgrowth and thereby the biodiversity is at high risk to decline. This study is based on an inventory of vegetation of overgrowth character and mosses. The frequency and spread of mosses is perceived as an indication of initial or present overgrowth. External factors that have been taken into consideration are wind-, wave- and ice erosion, the slope of the beach, wear and grade of exposure. The purpose of the investigation is to control the beaches grade of overgrowth and find out which external factor is of most importance for the maintenance of the biotope. The results show that the beaches environment is affected by the slope of the beach, grade of exposure, size, wear and overgrowth.

This essay presents and discusses a study that was performed in a multicultural school, where the teachers, since August 2004, have obtained internal training in how to work with language development. The objective with this essay is to investigate how the connection between language development and the development of knowledge can be understood and apprehended by teachers working in this school, and furthermore, to show how a language developing way of work can be accomplished in the teachers daily work.Moreover, I have studied which objectives and strategies, the three language developers in charge of the training of the teachers, have concerning this work, furthermore I have looked into if these objectives and strategies differ from what the teachers understand and practically perform.Pauline Gibbons book, Stärk språket, stärk lärandet (2006), has become a base for this school?s work when it comes to language development. Gibbons presents theories and practical exercises which have their origin from Vygotskij, Halliday and Cummins. Their theories have also become my theoretical base in this study.I have made qualitative interviews with four teachers working in this school, and with one of the language developers.

Miljonprogram is a Swedish building program from 1964 to 1975. During that time about a million homes were constructed. Now, almost 50 years later, they are in desperate need of renovation. In order to fulfil the Swedish environmental objective to decrease energy consumption 50 per cent until 2050, considerable housing stock built under the Miljonprogram has to be renovated.Focus in this thesis is on the building services and theirs profitability that can decrease energy consumption in households build during the Miljonprogram. Building construction is not considered in this report.

Den så kallade ?gröna revolutionen? inom jordbruket inleddes på 1960-talet och innebar högavkastande grödor, ett oreflekterat högt användande av kemiska bekämpningsmedel, samt intensiv bevattning och mekanisering. En underdrift är att påstå att detta skapat minst sagt stora problem för jordens ekosystem. Ett alternativ för hållbar matproduktion är agroforestry, som innebär produktion av träd på samma mark som produktion av jordbruksgrödor. Systemet är bland annat utvecklat för att förbättra ekologiska samspel.

This thesis was performed at Scania?s purchasing department of non-automotive products inSödertälje, Sweden during spring 2007. The management of the purchasing department ofnon-automotive products believe that their internal customers might not have fullunderstanding of what the purchasing department does. This is a problem because the internalcustomers might not use the contracts negotiated by the purchasing department or they mightnot involve the purchasing department when making purchases.The purpose of this thesis is to examine if and how the internal customers? perception deviatesfrom the purchasing department?s perception regarding the task of the purchasing department.And also to create a communication package with the purpose of increasing the internalcustomers understanding of what the purchasing department does.

The purpose of this thesis is to study whether there is a demand for sawn wood products of large dimensions and planed goods among Wallnäs AB:s customers. The thesis consist of two main parts, one survey among Wallnäs present customers and another one which purpose is to increase Wallnäs customer base. Finally there is a chapter that describes what properties the raw material has to have in order to produce the demanded products. The survey to the present customers was conducted through a questioner. A sample of those who stated an interest for either sawn wood products of large dimensions or planed goods, were later contacted for a telephone interview. To reach out to new customers, relevant companies has been identified through the Swedish Trade Councils data base and through the member list of the Timber Trade Federation.

Our understanding is that responsibility is shifting from the community towards the individual within the field of social work. This resulted in our essay, which aims to study how the representatives within social service assistance and churches in Helsingborg work with personal power. Our aim is also to illustrate how these representatives view the boundaries of responsibility between the individual and the community. Our questions are: How do the representatives work with personal power from a micro and macro perspective? How do the representatives look upon their position as representatives? What do the representatives consider as responsibility of the individual respective the community? And; Are there preventing factors from individual responsibility? We obtained our empirical material from a qualitative method consisting of interviews.

Framöver kan vi vänta oss ett varmare och mer nederbördsrikt klimat i Sverige. Detta beror till stor del på den globala uppvärmningen, som huvudsakligen orsakas av den ökade mängden växthusgaser i atmosfären. Högre temperaturer bidrar bland annat till att havsisarna smälter snabbare vilket höjer havsnivån. Ett varmare och fuktigare klimat kommer att på olika sätt påverka mark, byggnader och infrastruktur. En höjd havsnivå leder till att kustområden i högre grad drabbas av översvämningar och erosion.

One of the areas in which current theory on entrepreneurship is ambiguous is in the explanation of how entrepreneurs act when entering a new market. One author that has attempted to contribute in this area is Saras D. Sarasvathy who has tried to explain the entrepreneurs reasoning through the theory of causation and effectuation. The former refers to a reasoning that takes the effect of an entrepreneurial action as given, while the latter looks upon the effects as uncertain, while only the means are given. With a foundation in this theory, Sarasvathy claims that when entrepreneurs enters a new market the level of environmental uncertainty is so high that reasoning based on causal relationships is rendered useless.

This study concerns the energy future of the county of Stockholm up until 2050 and describes how the energy consumption can be compared to today with the use of scenario methodology. Within energy future studies the backcasting approach is well known and has been put to use in this study. Due to the characteristics of backcasting the study is self-fulfilling, i.e. the future energy scenarios presented in this study satisfy the targets set up in this study. In the light of what may be the largest challenge of our time ? the climate change - the aim of this study is to describe how the energy consumption in a fossil fuel free Stockholm county in the year of 2050 may be.

Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.
