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.

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.

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.

It?s not unusual for people to upload photos to the Internet nowadays. Despite the fact that there are benefits from doing this, there are also some risks that people should take into consideration before they share private photos. The aim of this survey was to investigate how users of different ages respond to risks related to photo sharing on Facebook. The participants were between the ages of 16 and 64.According to the results it appears that in some cases, even if they can?t be statistically proven, there are patterns that indicate that younger people are more careless and that older people are more careful when it comes to photo sharing on the Internet.

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.

Early Swedish films from the 1910?s and 1920?s are not only an important part of Sweden?s cultural heritage, but also an important part of the international film heritage. This period is often refereed to as the golden age of Swedish film history. Despite this fact, the possibility to watch Swedish films from this period is very small and the main purpose of this thesis is to examine why the availability of these films has such low priority in the Swedish film policy and at the Swedish Film Institute. With the use of policy analysis, I study governmental policies and policies from the Swedish Film Institute for early Swedish films and seek to identify the policy problem and its different parts.

The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.

Syfte och frågeställningarSyftet med studien var att undersöka om en kortare period av motiverande samtal (MI) kunde påverka livskvaliteten positivt hos en arbetande population. De tre frågeställningarna var: Kan en kort period av MI förändra livskvaliteten positivt? Vilka eventuella effekter har en kortare period av MI på livskvaliteten? Finns det några skillnader i eventuell förändring av livskvalitet mellan kön, ålder samt utbildningsnivå?MetodStudien bestod av två MI-samtal med tre veckors mellanrum, samt en enkätundersökning som genomfördes före och efter samtalsperioden. Ett företag kontaktades och deltagarna rekryterades genom information på företagets intranät. 25 anmälda bildade MI-gruppen och därefter efterfrågades kontrollgruppsdeltagare via mail, 23 anställda bildade kontrollgruppen.

Detta arbete handlar om grammatikens roll i språkundervisningen. Syftet med arbetet är att undersöka hur grammatikens ställning i språkundervisningen har utvecklats från 1960-talet fram till idag. För att få en inblick i detta ämne, har jag studerat och analyserat innehåll i styrdokument från 1965 till 2000 och i franska läromedel för nybörjarspråk på gymnasiet från motsvarande period. Med stöd av litteratur om språkundervisning, har jag försökt att ta reda på hur denna utveckling ser ut genom att titta på grammatiken som produkt, d v s att tala om språket, och på grammatiken som process, d v s att använda språket i sitt rätta sammanhang. Dessa två sätt att se på grammatiken utgör en bra utgångspunkt för att få en helhetsbild av grammatik, och när det gäller att utveckla språkförmågan är samspelet dem emellan viktigt.

Kevin Roberts has extended the comprehension of strong consumer brands to a higher level where loyalty beyond reason is established. He calls this new status Lovemarks. As the concept of Lovemark has only been applied in B2C markets, this thesis is directed to find out the applicability of Lovemarks in B2B context. In order to fulfill the research purpose, three main questions are answered based on a cross-sectional research approach: What role do intangible factors play in B2B branding? Is the idea of B2C Lovemarks transferable to B2B context? How should a B2B Lovemark be characterized? The results of the qualitative interviews indicate insights of high investment and involvement, integrated brand communication, balance between function versus emotion, brand?s trustworthy personality, customer partnership, and finally, the potential establishment of B2B Lovemarks.

In this study, my intention has been to examine how the ambiguous concept of corruption is constructed by the press. Emphasizing the media?s representations of the socially constructed and context-specific concept, this work adopts a critical perspective on discourse, together with an approach of conceptual history. Finland has for many years been appointed as one of the least corrupt countries in the world, signing several international conventions against corruption since the 1990s, which in turn has led to an increase in discussion regarding the phenomenon. By conducting a multi-method study, my aim has been to analyse the possible changes in the definition of ?corruption? in the Finnish newspaper Hufvudstadsbladet during the period 2000-2013.

Sjukfrånvaron i Sverige ökade kraftigt i slutet av 1990-talet och drabbade även högre utbildade personer som tidigare inte varit sjukskrivna. Många människor tillbringar större delen av livet på att arbeta och arbetsmiljön påverkar medarbetarna på olika sätt, där ledarskapet är en faktor som påverkar hälsan. Arbetsplatsen anses därför vara en av de hälsofrämjande arenor där insatser för att förbättra hälsan kan genomföras. Att ledarskapet påverkar medarbetarnas hälsa anses vara en självklarhet, men det finns inte så mycket forskning inom området.Syftet med studien var att undersöka hur medarbetare på en arbetsplats med låg sjukfrånvaro upplever att ledarskap bidrar till hälsa på arbetsplatsen. Studien är av kvalitativ ansats där data samlades in genom telefonintervjuer med fem personer.
