In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

För att erhålla en befuktning i andningsfuktaren tillförs en saltlösning. Befuktningsförmågan beror av salthalten i lösningen. För närvarande tillförs salt manuellt till lösningen.

Annorlunda färger på djur har fascinerat människan i alla tider. På många husdjursslag har färgen ingen direkt betydelse för produkten utan har ett mer estetiskt syfte. Detta gör fåren till ett unikt husdjur då vit färg länge har varit av ekonomisk betydelse och hos ullproducentervärlden över ser man ofta bara vita fårflockar. Trots detta dyker då och då färgade lamm upp och ger en ekonomisk förlust då färgad ull inte betalas lika bra. Vit färg har dock visat sig ge störningar i form av fertilitetsproblem och detta har gjort att många ullproducenter iställetinriktat sig på färgade får med naturfärgad ull.

In this study our aim is to display a series of possible mechanisms which operateswithin the regions and societies were child soldiers were frequently andextensively used in combat tasks. Our study is based on the assumption thattoday's peace-building strategies are inadequate to describe certain problemsfaced by many post-conflict countries, especially in Africa. We argue that largeformations of child soldiers will, if not properly and immediately addressed, causeserve and structural problems in society, gravely hampering growth andinstitutional capacity. The Issues of Post Traumatic Stress and societal insecuritybrought on by the use of child soldiers poses a serious threat to society as a whole.In this study we use Uganda as an illustrative case to describe the mechanisms atwork..

Den termohalina cirkulationen är en global havscirkulation driven av densitetsskillnader, som gör att varmt vatten transporteras mot polerna och kallt vatten mot ekvatorn. Densiteten påverkas av temperatur och salinitet (och tryck, som vanligtvis ignoreras). Därför heter cirkulationen termohalin. Saliniteten minskar när vatten tillförs genom nederbörd, havsissmältning eller landavrinning. Saliniteten ökar genom avdunstning och isbildning.

Syftet med denna kunskapsöversikt är att bidra till en ökad förståelse kring kostens betydelse för barns kognitiva utveckling samt deras förmåga till inlärning:Vilken påverkan har kosten förbarns inlärning och kognitiva utveckling? Metoden är en kunskapsöversikt med 13 analyserade artiklar. Resultatet visar att lång amningstid ger färre ADHD symtom, hyperaktivitetoch impulsivitet hos barnet. Mycket snabbmat, salt, friterad mat, rött kött, söta drycker och sötsaker bidrar till en sämre minnesfunktion och inlärningsproblem. Att äta hälsosam mat med mycket fisk, frukt och grönt bidrardettatill en god hälsa och mindre symtom av ADHD, hyperaktivitet, impulsivitet och bättre akademiska resultat..

This paper attempts to illustrate a gap when it comes to the knowledge about unpaid volunteers in Swedish organisations. The person-oriented explanations of individual preferences when choosing an orientation in which to volunteer does not suffice to explain and enlighten the fact that there is a gender-based division that orientates women towards voluntary work within organisations with a social direction, while men tend to choose sports-oriented voluntary tasks. This illustrates a pattern that is common in society in general. Eight interviews including four women volunteering in socially oriented organisations and four men in sports-oriented organisations have been conducted. An attempt has been made to explain results from earlier research as well as the respondents reasoning about their voluntary work with gender related theories.

SammanfattningBakgrund Det bedöms att 10 - 60 % av alla patienter på norska sjukhus och sjukhem är undernärda. Mer än hälften av dessa patienter går ned ytterligare i vikt under tiden de är inlagda på sjukhus. Norska riktlinjer (Kosthåndboken) för måltidsplanering på vårdinstanser rekommenderar systematisk måltidsplanering för att förebygga och behandla undernäring på sjukhus.Syfte Att ta fram information om aktuell situation gällande måltiderna som serverades vid ett regionalt sjukhus i Nordnorge och jämföra med nationella rekommendationer, samt att ta fram underlag för ett åtgärdsförslag. Metod Studien är en tvärsnittsstudie som genomfördes vid Nordlandssykehuset, Bodø, Nordnorge. Samtliga huvudmåltider i de två huvudkosterna (Nøkkelrådskost och Energi- og næringstett kost) näringsberäknades och jämfördes med rekommendationen. Recept, produktinformation och portionskalkyler inhämtades med intervju av kökspersonal.

Moldova is one of Europe?s poorest countries with a struggling business environment and an unpredictable political situation. The purpose of this thesis is to understand the implications of corruptions and why networks have come to play a key role in the Moldovan culture and if the formations of network are due to heritage or an effect of functionalism. The focus of the study is also to explain how the networks develop and the formation and maintenance of loyalty and trust among the members of the network. The study is of a qualitative nature that uses a key informant sampling method to get access to members of different business networks.

The purpose of this study is to explore how different discourses about risk linked to HIV prevention is likely to affect the decisions on the distribution of state funding for preventive activities aimed at 'men who have sex with men' (MSM). This by making qualitative interviews with principals that have an impact on this decision. Using a discourse analytic approach, based on both theoretical and methodological foundations, I investigate the discursive constructions of risk of HIV linked to certain groups and behaviors. MSM is found in the material placed into two different formations of groups, on one hand by the behavior on the other hand on the basis of identity. The identity position is organized discursively from a ?victim? position while MSM provides an "operator" position.

The purpose of this essay is to examine formations of gender and class of so called horse girls in a riding school located in Stockholm, Sweden. The essay is based on interviews with six girls in the ages between fifthteen and eighteen. Through the theoretical framework of Judith Butler and Beverley Skeggs, I examine how the girls negotiate the boundaries and probabilities within doing gender in an upper and middleclass associated area. As a result of its female domination, the stable functions as a place where the girls can dislocate themselves from otherwise normative feminine practises. This is possible since the premises of the stable are constructed in the light of the heterosexual matrix, where the girls organise themselves within the heterosexual girl collective.

Ohälsan i världen så som i Sverige är stor (Becker, 2002). Varje år dör flera personer av kostrelaterade sjukdomar så som hjärt- kärlsjukdom (Socialstyrelsen, 2001). Dåliga matvanor är en av de största påverkbara riskfaktorerna för flera kroniska sjukdomar (WHO, 2003). För att minska ohälsan har Livsmedelsverket och Folkhälsoinstitutet på uppdrag av regeringen tagit fram en handlingsplan för bättre matvanor och ökad fysisk aktivitet. I handlingsplanen finns en punkt som säger att vi bör öka konsumtionen av nyckelhålsmärkta produkter (Livsmedelsverket & Folkhälsoinstitutet, 2005).

I have studied the Swedish artist formation ?1947 års män? with a sociological perspective based on the ideas of Pierre Bourdieu. I initially made a study of the group as a whole, and after that I chose to focus on the sculptors Liss Eriksson, Arne Jones and Knut-Erik Lindberg. I have examined why some of the artists in the formation became more successful than others. My results show that the ones who were versed in culture or came from an economically or intellectually stronger background also were considered to be the most pioneering artists.

The purpose of this research is to investigate the group constellation that is, what thoughts, feelings and sensations that arise when students and pupils change groups. The study will also affect students and pupils knowledge of why they should work in groups. Their perceived security will also be something that this study is looking for.The main questions of this study are:How does students and pupils experience the phenomenon of "group replacement"?What is considered to work or not work in the new group formations?The method that is used in this study is based on six qualitative interviews with students and pupils from three different levels of education. The target groups are college and high school students.

The purpose of this ideology critical study is to investigate the hidden content in the reform Gy11 and compare it with the concept new public management. After the clarification of the hidden content, we compare the structure of the organization in Swedish high schools with the structure in public sector called new public management. The main questions of this study are the following: Is it possible to see the foundation of new public management in the Swedish high schools when it comes to the views of knowledge and the formation of goals? Which similarities can we find when we look at the organization new public management and the Swedish high school?The result showed many similarities, both regarding the views of knowledge and the formations of goals. The structure of new public management has been largely implemented in the Swedish high schools and the schools now focus more on instrumental knowledge rather than universal knowledge based on understanding.This is not surprising due to the social progress.
