Storjuktan ? Rekonstruktion av ett sekels kvicksilverbelastning. : En undersökning av kvicksilverkoncentrationer i daterat bottensediment.

The aim of this study was to examine the current and historic mercury(Hg) load of the lake Storjuktan due to its recent exposure to a local potential source of Hg in form of the Sulphide mine Blaikengruvan(2006) and an earlier potential sources of Hg-load, the damming of the lake(1960s). Sediments were extracted using a HTH-sampler, freeze-dried, and analyzed for tot-Hg, LOI and activity of 210Pb and compared to samples extracted prior to the opening of the mine(2006). Constant initial concentration (CIC)-dating model was used for dating the samples. Low levels of Hg (100ng/g) were found throughout the lakes sediment. The highest levels of Hg(220ng/g) was detected at a depth of 4-5cm dating back to the mid 1970:s, suggesting that increased levels of atmospheric Hg rather than damming of the lake has caused the increase of Hg.

Normalitet och styrning i en förskola för alla (Normalization and governing in a pre-school for all)

The purpose of this study is to analyze how special education is done in relation to what is considered "normal". The aim is to discuss how the normalization discourse appears in a pre-school for all and, by extension, how the need of special education is articulated in relation to the normalization discourse. This study also intends to discuss how the perception of what is normal affects special education in pre-schools. The study draws upon previous research within the special education area through which we make our position. Since there is only a few studies in this chosen field which are based on empirical data, our study indicates the importance of more research in this field.

Förebilder i textilslöjden : Förekomsten av förebilder och betydelsebärande slöjdföremål och hur de används i slöjdundervisning

English abstractTitle: Islam and the limitations of the public will of choice.The purpose of this paper have been to investigate how three modern Islamic theorists view the limitations of the public free will of choice based upon their interpretation of the Islamic theology and doctrine.The paper focuses to highlight how all three chosen Islamic theorist interpret the Islamic doctrine based upon my elected theses and more specifically pinpoint were the free will of choice ends, and Islam as a religion starts to take hegemony. The paper?s aim is to further an understanding that in the modern world and as a effect of increased literacy, Islam has been somewhat inclined to split into several Islamisms, based upon the variety of fatwa?s on the Islamic doctrine that is available online. Therefore it remains to the modern day Muslim, to individually decide whether they choose to follow the message of the Holy revelation in the Quran or trust a mufti?s fatwa in their everyday life as a Muslim.The material used and analyzed in this paper is prime source material.

A common health complaint affecting the quality of life in elderly persons are sleep difficulties. Physical activity is claimed to improve sleep quality and the maintenance of a normal circadian rhythm. Several studies have shown positive effects of physical activity on sleep quality, still the evidence of physical activity as sleep-promoter is insufficient. Aim: The aim of this study was to investigate associations between physical activities and sleep quality in persons ?60 years of age.

Segmentering och klassificering av LiDAR-data

With numerous applications in both military and civilian life, the demand for accurate 3D models of real world environments increases rapidly. Using an airborne laser scanner for the raw data acquisition and robust methods for data processing, the researchers at the Swedish Defence Research Agency (FOI) in Linköping hope to fully automate the modeling process.The work of this thesis has mainly been focused on three areas: ground estimation, image segmentation and classification. Procedures have in each of these areas been developed, leading to a new algorithm for ground estimation, a number of segmentation methods as well as a full comparison of various decision values for an object based classification. The ground estimation algorithm developed has yielded good results compared to the method based on active contours previously elaborated at FOI. The computational effort needed by the new method has been greatly reduced compared to the former, as performance, particularly in urban areas, has been improved.

Heliga vatten : Vattencentrerad kult och vattnets symbolik under Skandinaviens kristnande

This essay aims to explore continuity in water centric cult within the period of the Christianization of Scandinavia (ca 800-1100 AD) and to understand the changing of symbolism of water in pre-Christian cult and early Christian religion. It has previously been thought that Christian priests took over the old holy wells and renamed them after saint, all to ease the pagan people into a Christian lifestyle. But archaeological evidence shows that the cult at these wells, and other water centric sites, where almost completely abandoned a few hundred years before the Christians came to Scandinavia. The Christians should not have felt the need to transform this tradition since it was only practiced in a very small and supposedly private scale. On the contrary, religious activities at these wells seems to increase with the new religion and perhaps this is explained by Christianity itself.

Klimatneutrala företag - kan IT minska utsläppen?

The attention on environmental issues has never been as huge as today. The climate is changing and more and more evidence suggest that the cause behind climate changes is an increase of carbondioxide into the atmosphere. The increase in turn is considerd to be an act of human activity. Therefore some companies have decided to become climate neutral and implement information technology in their business in order to reduce their emissions. This thesis has three aimes: to calculate a small company´s carbondioxide emissions, study whether or not information technology could help to reduce these emissions and furthermore find out why some companies decided to become climate neutral and describe the concept climate neutral.

Leken : En studie om kommunikation i fantasilekar

The aim of this study was to examine how children in the age of 5 are communicating in play at the preschool and how their fantasy games are different from each other. In this study, I have gained a greater insight on how to control children's imagination games.My approach has been the observation of three fun times where I also used me out of a voice recorder to record children's voices when their children are communicating with each other during the time of play at the preschool.The results of my study showed that children's fantasy games based on children's past experiences in which children use different themes and characters. The children's communication activities are different from each other. Children have different themes but the deck is based on imagination and communication.Fantasy games that children perform is rooted in the experiences that children get through to experience and see the reality.

Kan den svenska avkastningskurvan användas som indikator för den svenska inflationen?

Abstrakt The yield curve as a forecasting tool for inflation has been thoroughly investigated. However, most of these studies considered only the major economies, such as the U.S. economy or the major European economies and not a small open economy such as the Swedish. The Swedish economy should be much more affected by the world economy then the bigger economies. The purpose with this study is then to investigate whether the Swedish yield curve, or the Swedish interest rate, can be used as forecasting tools for the Swedish inflation.

?På sätt och vis är det tydligt, på sätt och vis är det inte det? : en studie om kuratorns upplevelse av sin yrkesroll och det psykosociala synsättet inom habiliteringen

The purpose of this study is to increase an understanding of what prevents the mandatory reporting law, based on the preschool staff's approach to mandatory reporting law about child abuse and neglect to social services, and how these barriers affect their decision to report. The study will also understand what preschool staff experience facilitates the mandatory reporting process and what can be done to improve the process even more. The questions of the study were based on the purpose of the study and have been formulated in two questions:What prevents the mandatory reporting law requirements for preschool staff and how can these barriers be removed? What facilitates for preschool staff to be confident in the decision to report child abuse and neglect, to social services?The study used qualitative semi-structured interviews with five people working at the preschool, including two preschool teachers and three childcare workers. An interview guide was designed as a help to answer the questions about what the barriers are and what it is that makes it easier for the preschool staff, regarding the decision to report cases of child abuse and neglect to social services.The results, based on the five interviews , shows preschool staff's thoughts of the knowledge on the mandatory reporting law, the mandatory reporting process, their perspective of the mandatory reporting law and the uncertainty surrounding the mandatory reporting law.The study's analysis consists of the results that have been analyzed using the theory of social representations, in which the analysis shows an understanding of how the preschool staff act and think about the mandatory reporting law requirements based on their everyday knowledge.

In recent years it has become more common with corporations based on projects.

Dubbelkönighet hos mört : normalt eller miljöinducerat?

A number of chemical agents, and their degradation products, have been recognized as having estrogenic activity on animals. On fish they interfere with endogenous estrogen and in many cases mimic its activity, thus increase estrogenic reponse, with elevated levels of vitellogenin. Hence they are called Endocrine Disrupting Chemicals, EDCs. Vitellogenin levels is often used as a biomarker of exposure to estrogenic pollutants. Wastewater from sewage treatment works contains chemicals known as EDCs, and there are evidence of roach (Rutilus rutilus) living in recipients of such wastewater having traits of both gender, i.e. oocytes in male gonads (intersex) on histological examination. This study was done on roach living in Lake Funbosjön Uppland, Sweden.

Mervärdeskapande på Internet : En undersökning av Internetbaserade resebyråer

The purpose of this thesis is to examine whether Swedish, Internet-based travel agencies, acting on a consumer market are working towards creating added value for their customers. If that is the case, how and why do they use such a mode of operation.The theoretical framework was based on Grönroos´ ?Augmented service offering?, which treats added value as an addition to the core service. The services offered on five of the larger companies´ websites on the market were examined and 3 representatives of the five companies were interviewed.The study shows that 2 of the examined companies did not produce any added value, while 3 of the companies did produce added value for the customer. The added value was generated through packaging of core-, facilitating- and supporting services for the purpose of differentiating the company towards competitors and generating service fees..
