Gotland is an island with a rich history. One unique thing about it is the picturestones. There are, today, 565 known stones and fragments found on the island of various dating. The dating time spans from 400 ad to 1100 ad. This essay is meant to discuss the dating issue of the early picture stones dated to 400-700 ad and discuss the relevance and validity of the today?s dating.

Hedge funds have the past few years become an increasingly popular investment alternative and in the last decade hedge fund assets managed have quadrupled to USD 2000 billion, a growth rate of around 25-30% per year. One explanation for this substantial increase is that hedge funds' minimum limits on capital invested has declined, which have made ??them available to retail investors. The recent turmoil in financial markets has also contributed to investors finding their way to hedge funds, whose goal is to generate stable returns regardless of how the market develops.Using Sharpe?s, Treynor?s and Jensen's performance measures, I have investigated whether hedge funds manage to generate higher risk-adjusted returns than traditional managed funds.

This dissertation is done as a preparatory step for the action plan of environmental protection shall issue to preserve the Phytoecia nigricornis in the country when it is red-listed and classified as vulnerable (VU). My task was to investigate the prevalence of the Phytoecia nigricornis in Halland County. They wanted to see if it existed in Halland (Ehnström, 1999). If it did not exist they wanted to know how to improve its habitat.the Phytoecia nigricornis is difficult to inventory because when it is larvae it lives in the roots and lower parts of the trunk of the Solidago Virgaurea plant and the adult beetles only keeps to Solidago Virgaurea by mating and egg laying and larval caterpillars when they hatch (Bily, 1989; Molander, 1999). Often it is overlooked or missed, and one question was whether it existed  in the whole country or only in those parts where it was previously found in, Skåne, Blekinge and Östergötland (Ehnström, 1999).One problem for the Phytoecia nigricornis is that their habitats is declining.

The aim of this study is to describe a number of type stands of lodge pole pine in Norrbotten with respect on stem volume and total biomass. Further questions to answer is if there is stand characteristics that make the stands more suitable for pulpwood in early thinning, or if it is better to apply whole tree harvest. The study shall also give an indication if bio energy can be an economical interesting alternative for Sveaskog. Sampled trees represented the variation in the different stands. Five trees were selected from each stand to represent that stand. Stem volume and biomass (kg dry weight (DW) per hectare) for each fraction was calculated.

Detta examensarbete behandlar det biologiska reningssteget vid Stora Enso Fors AB kartongfabrik.Examensarbetet omfattar 20 p och ingår i slutskedet av Magisterutbildningen, 60 p, i Kemiteknik med inriktning industriell ekologi vid Kungliga Tekniska Högskolan i Stockholm.Stora Enso Fors AB är en kartongfabrik som är lokaliserat i Fors strax nordost om Avesta.Tillverkning sker av både mekanisk massa samt kartong. Fabriken har ett eget reningsverk som tar hand om avloppsvattnet från processen.De biologiska anläggningarnas utformning har under årens lopp utvecklats främst genom bättre syresättning i luftningsbassängerna samt förändringar i avloppsvattnets sammansättning. För att klara av dessa förändringar kan styrparametern slamhalten behöva ersättas med andra alternativa styrsätt.Examensarbetets syfte är just att studera möjligheten att styra det biologiska reningssteget vid Fors kartongpappersbruk efter nyckeltalet nettoslamproduktionen. Projektet innefattar även att undersöka hur COD-reduktionen och mikroflorans sammansättning påverkas av denna styrparameter.Litteraturstudier av reningsteknikens processer har utförts samt den befintliga reningsanläggningen i Fors har studerats. Det första steget i projektet var att besluta vilket målvärde som skulle användas på nettoslamproduktionen som skulle användas under en försöksperiod där den biologiska reningen skulle styras efter nettoslamproduktionen.För varje dygn under tre olika tidsperioder ( period 1, period 2 och period 3) har driftsdata samlats in och sammanställdes och därefter beräknades nettoslamproduktionens dygnsvärde.Driftsdata för period 1 och halva period 2 har använts som underlag för att kunna bestämma målvärdet för nettoslamproduktionen.

My master?s thesis is a study of acquisition of photographies during 1958-2008. The questions I proceed from is what patterns lies behind the Royal library's acquisition of photography and how the process of acquisition looks like. The theoretical base which I lean on consists partly of a problematization of the process of cultural heritage and partly of organizational theory. The problematization of the process of cultural heritage is my foundation of this essay.

Today many sociologists speak about the modern world and the god and bad that it brings. In association to this discussion there is a tendency to speak about an increased individualization, a process that often also means more choices and possibilities. But in addition to this follows a big responsibility for how we choose to live our lives, since our choices not seldom also influences other people, both locally and globally. The aim of this essay is to investigate the importance of non-profit organizations with social direction in our Swedish welfare society and thereby also in a modern world where people's individual choices are becoming all more important. In order to answer my main issue I have implemented thirteen qualitative interviews, of which ten of the informers are from different non-profit organizations and three from different stately authorities.

Human presence has always influenced the surrounding areas, the forest as well. Structure and species composition have changed during human land use. Knowledge regarding these changes should be of great interest for conservation and forestry. We have analyzed human impact on the tree species composition on five study sites during 2000 years in Ångermanland, Sweden. More specifically the change in tree species composition in percentage amongst alder, birch, spruce and pine over time.

År 2013 var den globala omsättningen för modeindustrin ca 76 tusen miljarder svenska kronor (Office of Textiles and Apparel, 2014). Bara i Sverige omsattes det 229 miljarder svenska kronor år 2012 inom denna sektor, en ökning på 11 % från föregående år (Tillväxtverket, 2014). Att modebranschen är under ständig utveckling och ökar i tillväxt kan man se då dessa siffror stiger varje år. Statistik från 2014 visar att trots denna ökning så överlever endast 47 % av nystartade modeföretag de tre första åren (Statistic Brain, 2014). Så hur lyckas man som modeföretag i early stage-fasen att med begränsade resurser stärka sitt varumärke och hålla sig kvar på marknaden? I denna studie berörs olika delar så som traditionell marknadsföring, okonventionell marknadsföring, branding samt transparens, där huvudfokus ligger på företag i early stage- fasen av sin uppstart.

The audiologists´ knowledge-domain is generally described as a unique combination of medical, technical, social and behavioural sciences. It gives prominence to the importance of an adequate education relating to the knowledge-demands the students´encounter during their trainee-period. However, an important question is if the educational content corresponds to the knowledge-demands during the training? Aim: This study aimed to identify the knowledge-demands of students during their trainee-period. Furthermore, to identify how the students´ actual knowledge was related to the encountered knowledge-demands.

This paper deals with stable isotope analysis on the children of the early Christian cemetery in Varnhem, Västergötland. Human bone and tooth material from the cemetery has been analysed for stable carbon, nitrogen and sulphur isotopes. The analysis showed that the diet had been homogeneous and that the children had been breastfed, with a possible exception of the child from grave 100..

The aim of the study was to investigate social workers and managers experiences of ending child welfare investigations within the statutory period of four months. We also investigated their experience of investigation time is used in practice. To get answers for our purpose, we conducted a qualitative study. We strategic selected three social workers and four managers to our interviews.The results showed that both social workers and managers have experience with child welfare investigations that are not completed within the statutory time. A township that departed had no experience.

During and after World War II Sweden was spying in the occupied Baltic countries which had been occupied, from 1943 by Nazi Germany and from 1944 by the Soviet Union. It began in 1943, with the Germans still occupying the Baltic countries, when Sweden and its intelligence service ?C-byrån? recruited volunteers among the Baltic refugees in Sweden and sent them back to the countries they had fled from. Many of the Baltic refugees to Sweden were men aged 25-45 so the Swedish intelligence service had a good recruiting source. This started the first period of intelligence operations in the three Baltic countries.

This thesis explores in which ways the portrayal of the event known as the Stockholm bloodbath has changed during the period 1869-1996. This is done through textbook analysis. In Sweden, history has been a school subject since the 17th century, and has throughout its history had a formative role in the Swedish school system. In the middle of the 19th century it was specifically stated that the aim was to help students nurture a sense of national pride and love of country. The aim of the study is to investigate how nationally loaded events have been portrayed in text books, as well as if and how the evolution of said textbooks reflect the evolution of the history subject as a whole.

GE Healthcare operates in Uppsala (Sweden) and develops systems, equipments and medium to purify medical substances. Discussions with the local authority concerning planed far-reaching changes and upgrades of the biological process techniques for sewage management, aroused the question about revising the terms of permit for the activity. Therefore it seemed necessary to evaluate a newly installed biological process technique, which is the background of this thesis. The evaluated biological treatment process was built in 2003 and consists of a biological reactor filled with moving bed carriers with a high surface area for biological growth. At the time of the project the biological wastewater treatment plant consisted of a flow equalization facility and two following parallel biological processes; a biological reactor with moving bed carriers and a tower trickling filter.The aim of this thesis was to survey the function of the biological reactor with respect to the reduction of organic matter.
