Hallsta paper mill uses large amounts of water during the pulp and paper making processes. The wastewater is treated in two separate activated sludge processes referred to as BIO 1 and BIO 2. The main aim is to reduce the organic substance content, measured as COD (Chemical Oxygen Demand) before the wastewater is released into the environment. Since the effluent produced is very rich in organic substances, the addition of nitrogen (N) and phosphorus (P) are necessary to give satisfactory treatment results. Problems with sludge bulking sometimes occur which lead to increased levels of suspended matter and nutrients in the effluent.

Syftet med föreliggande studie var att bidra till utvecklandet av självskattningsskalor för föräldrar till barn med ätstörningar. Skalor som ska kunna användas diagnostiskt men också vid utvärdering av behandling. Två instrument utprovades; AESED som mäter i vilken grad föräldrar anpassar sig till ätstörningssymtomen och hur påverkan på familjesystemet ser ut med utgångspunkt i Schmidt och Treasures modell om vidmakthållande av symtom, samt FQ som mäter expressed emotion. Detta kompletterades med HAD som mäter ångest och depression. Studien genomfördes vid SCÄ ? Stockholms Centrum för Ätstörningar och data jämfördes med motsvarande material från Västerbotten.

In the 1960?s, Paul Hersey and Ken Blanchard developed a theory called Situational Leadership. Situational Leadership is a model where the leader analyses the needs of the situation and the needs of the people to be led. After analysing the situation, decision is made on what leadership style to adopt. The Situational Leadership model was developed in a company environment.

The essay is about the Nobel Library's investments in fiction, the change of certain linguisticareas since 1904 and the purchase policy of the Library. The paper contains an introductoryhistorical chapter, where I describe the history of the Swedish Academy, the life and willof Alfred Nobel and in conclusion a description of the Nobel library of the Swedish Academy.When writing this essay I have used a combined qualitative and quantitative method, meaningthat I have interviewed the librarians of the Nobel Library, studied the purchase catalogues,and kept statistics over the books.in different linguistic areas purchased since 1904 onwardwith an emphasize on years ending with "4". The outcome of this survey is that the purchaseof books within the different speech areas doesn't vary as much as first expected, and thatthere rises and falls within all the linguistic areas which could be further explored..

During pulp and papermaking process a huge amount of water is used. The wastewater contains a large amount of pollutants and has to be treated before it reaches the recipient. In March 2004 a new bleaching plant was started up at SCA Graphic Sundsvall AB, Ortviken?s paper mill using peroxide. The production of bleached thermo mechanical pulp and thus the load to the wastewater plant increased.

In some herds it has been observed that extremely short teats have become a problem; with a negative influence on the milking performance. The aim of this study was therefore to investigate to what degree the quality of the teats and the milk in cows with short teats is affected as compared with cows with normal teat length and furthermore if the milking performance could be improved by using a liner adapted to short teats. This study was divided in two parts. In the first part, it was examined if there were any differences between short teats and teats with normal length with reference to the milking performance, udder emptying, teat treatment, milk quality, and udder health. 11 pairs of cows were used and in each pair of cows one cow had teats shorter than 40 mm while the other cow had teats longer than 50 mm.

AbstractThe project "Sound and Play" have been implemented in collaboration with the toy company BRIO in Malmo. The purpose of the project was to examine whether and how BRIO in the future could develop toys around sound for Toddlers.The problem formulations that would be answered after completion of the project was "How could BRIO broaden its product range with the help of audio toys?", "How can you combine toys and sounds in an interesting way for children?", "How do you create a toy with sound that is fun for the child, but not annoying for parents?". Currently BRIO only has two toys with sound in this age group.The expression of the toy was going to be a mix of classic and cool and the overall feeling of the toy was going to be explorative and arouse curiosity in the child. This feeling would be communicated through simplicity and joy.

The aim of these two studies was to investigate the possible physiological, behavioural and emotional changes that appear after human-horse interactions and also to find an explanation to why they occur. One aspect that is discussed is whether the wellbeing of humans can be coupled to interacting with horses and of how the animals respond to the interaction. The first study was performed on 9 horses and their owners, both parts being subjects to registrations during 4 different interaction treatments. The second study was performed on 6 horses with registrations only being performed on the horses during 2 different treatments. Nine horses underwent 3 different treatments all performed by their owners (H = stroking of the horses forehead, B = brushing and M = stimulation of the withers) in addition to a control round (K). Each treatment lasted for 4 minutes but observations were performed until after 45 minutes from start.

We studied the understanding of public librarians of the required qualifications for a public librarian, what these qualifications embody and how they should be used, and if there are any differences between geographic regions. We also compared our results to the Library Code, which describes the responsibilities of the public libraries. To complete our study, we interviewed fourteen public librarians at eight different public libraries located in both urban and rural areas in Sweden. Our results showed that even though the qualifications specified by the Library Code were identical, they were emphasized and used differently by the public libraries included in our study. This illustrates that the public libraries prioritize and focus differently on the various aspects of the Library Code.

This thesis examines the relationship between OECD-DAC and Civil Society Organizations (CSOs) within an aid efficiency context. The ability for these two actors to cooperate is highly important and determines the outcome for a major part of the development aid in the new millennium. The development agenda for the new millennium emphasizes aid efficiency as a key to a more successful aid, and this requires increased cooperation between all actors. The analysis made is a discourse analysis. The discourse of aid efficiency is analyzed, both its preconditions and results.The analyze finds out that there is a gap between OECD-DAC and CSOs in terms of how to handle aid efficiency.

The use of chainsaws in both private forestry and commercial companies is highly associated with personal injuries and accidents with deadly outcome. As a result to this, a driver?s license for chainsaws was presented in the year 2005. To get the license you have to attend a course given by the Swedish Forest Agency or one of several private educators. This study is an evaluation of one course given by the Swedish Forest Agency in Uppsala.

This thesis discusses and analyses the existence of two different perspectives, a social and a technical one, in Library and Information Science (LIS). Most of the time the division between these perspectives seems to result in research only using either of them. This can be a problem when studying complex phenomena. We therefore see a need for a metatheory that unites the social and the technical. By presenting and analysing all doctoral dissertations published at the Swedish School of Library and Information Science (SSLIS) 1993-2005, we try to detect and critically discuss the dichotomy between the two perspectives.

The objective of the study is to examine whether the experience from language courses abroad has had any impact on the career choices for four individuals. Based on a qualitative research methodology, four semi-structured interviews have been executed. The two research questions have been answered by letting four people recount their experiences from language courses abroad linked to their self-images and career choices. The outcome is that the experiences from the language courses contributed to a more or less altered self-image. Most of all, the interpersonal abilities were fostered, which led to the formation of a self-image characterized by improved confidence in social settings.

The purpose of this study was to evaluate the different substrates that enter the digestion on Sundet wastewater treatment plant for production of biogas.This work have done an analysis of data about the biogasproduction from January 2012 to feburari 2013, this showed that the food substrates has a greater gas production than internal sludge.Through laboratory test the VS, TS and COD values for all the substrates used in the biogas production could be determinded. But the COD-method was less optimal for analysis of fat and food, therefore it optimized the method for fat but due to time constraints, this could not be done on the food substrates..

The following paper looks into MaternityPaternity leave and how the parents make use of it. The underlying reasons for the paper, is a pattern of unequal division of leave between the mother and father.By using a qualitative in depth interview technique with couples that have children between 2 and 3 years old we have looked for reasons why the decisions, around the division of leave, have been taken, and what factors influence the outcome.We have found that great importance is attached to, how, the negotiations are carried out between the parents, although these negotiations are influenced by a series of circumstances where the families economic situation influenced by the employment market are important factors.The results from the empiric part of the study showed a link between the childs age and which parent stayed home. Furthermore, the results show the families place in relationship to the structure of society also plays an important part in the concluding division of leave..
