Milk fever, or parturient paresis, is the second most common disease in Swedish dairy cows. The disorder is associated with the onset of lactation when some cows are unable to meet the metabolic demands of calcium to support milk production and therefore develop a state of hypocalcaemia. Clinical hypocalcaemia (milk fever) may lead to coma and death in severe cases but subclinical hypocalcaemia has also been shown to have negative effects on e.g. feed intake and production and to increase the susceptibility of the cow to develop secondary diseases. The nutritional strategy applied precalving is of great importance in preventing milk fever and e.g.

Background: Since1994, the EU NickelDirective is limiting the release of nickel from objects that are in prolongedcontact with skin. Despite this, nickel is still the most common cause of contactallergy in industrialized countries. This could implicate that other productswith short contact to the skin, which are not restricted by EU´s legislation inREACH (Registration, Evaluation, Authorisation and Restriction of Chemicalsubstances), could be a source of nickel or cobalt exposure. There is no limitfor cobalt release within REACH. To determine if there is cobalt or nickelpresent on the surface of a material and if metal can be released in contactwith the skin, there are quantitative and qualitative methods, such as the DMG(dimethylglyoxime)-test, the cobalt spot-test and a method for releasedetermination according to EN1811.Objectives: Laptops are not included in the REACH legislation.

This thesis deals with classification of the subject field history of medicine. The two classification systems SAB and NLM are compared in order to find out which one is the most adequate to organize a small collection of history of medicine. SAB and NLM are the two most commonly used classification systems in medical libraries in Sweden today. NLM classification system specializes in medicine and SAB is a universal classification system. Our purpose with this study is to find out the pros and cons of each system, whether the systems treat the subject history of medicine in a satisfactory way and what kind of classification system that is better for this assignment, a specific one or a general one.

The purpose of this thesis is to examine the quality notions used by the library personnel responsible for the video game department at Malmo City Library. Furthermore, the thesis aims to assess how these notions of quality relate to properties of the actual collection of video games. The empirical results are based on interviews with the responsible library personnel. The result is then analyzed by an interpretation of Carl Gustav Johannsen?s library adapted, theory-based, model of quality definitions.

In this Master's thesis we investigate the collection management regarding fiction for adults. The apprehension of fiction has changed over the years. From the beginning it was considered to be mostly educational rather than being the purpose of entertainment. As for today these views are not opposites to each other. Regarding this we discuss the problem concerning terms of quality.

Vattenfall hedge its future electricity production in order to decrease fluctuations in theresult. Hedging can in a simplified way be described as selling the future electricity deliveriesin long-term contracts so that the future price of the delivery becomes fixed. The contractsused are electricity forwards traded at the Nordic electricity market Nord Pool. Animbalance between buyers and sellers can lead to a situation where the forward price notequals the expected spot price. The difference between the forward price and the expectedspot price is referred to as the market risk premium.

The aim of this study was to develop a simple model for calculating stock costs for bio fuel at Billerud Karlsborg and subsequently recommending a suitable stock level of bio fuel. The stock components considered in the model are GROT (branches and tops), bark, dry wood chips, raw wood chips from barking and sawdust. The calculations are based on a probability distribution of historical deviations between ordered and delivered volumes. The model presents two different ways to manage the supply in case of irregular deliveries. The first way is to stock enough volume to cover the deviations and the second way is to compensate with a quick purchase from the spot market (at extra high purchase prices).

This master thesis focuses mainly on the concept of quality and how the librarians responsible for phonogram purchase use it. The main object is to investigate how the librarians responsible for the purchasing of phonogram works when in the process of selecting the phonograms and how they speak about the concept of quality. Based on this main object four problems has been addressed. The empirical material is interviews made with the seven librarians responsible for phonogram purchase at seven Swedish libraries. The result of this investigation is analyzed based on a theoretical framework created by Sanna Talja, which focuses on what a phonogram collection should contain.

Towards the end of the 1960s, the credit financed purchase was well established in Sweden. The Swedish households were able to purchase goods, which had been considered unnecessary, or even luxurious, in the past. On the other hand, effective means to handle the increasing amount of debt and potential debtors were introduced; credit rating was registered, trade with insecure claims increased and if debtors could not fulfil their obligations, the creditors often used harsh or undue methods. By introducing Inkassolagen (1974:182), the legislator hoped to regulate the debt recovery process and ensure the fair treatment of debtors. The legislator also introduced liability for damages caused by a creditor in the collection process.

The character of a pattern carries through to the context in which it is placed. Each pattern tells a story. By interpreting our surroundingenvironments we become inspired, and the patterns in turn can become part of our own narratives. This project was fuelled by my fascination and desire to explore patterns. My method of exploration was based on prior knowledge of patterns and interior design.The question became how can I apply my knowledge of interior design to pattern design and how could I best translate the brief intoa language of colour and shapes? The aim was to develop my knowledge of pattern design as well as to use this opportunity to combine my design methods with those of a professional designer.

In this essay I analyze the way my collection of poetry relates to the concept cyclic. What is cyclic and what different interpretations are there concerning the concept? Which other related concepts are there regarding things that seem to reoccur regularly? How does the cyclical, the circular, relate to the linear in regard, for example, to the perception of time? Life often creates the sense that different phenomena and experiences repeat themselves. Different processes are conducted according to regular or irregular cyclical phases, situations seem familiar and events can be relived.         Starting from my writing project Sinnligt kviller, a collection of poems, I discuss these questions in themselves and the impact they have had on my collection. I describe the phenomenon cyclic as a result of the emotions and moods this term creates in a more or less decisive way.         The intention with this paper is to show how Sinnligt kviller offers different perspectives of and reflections upon the various feelings provoked by the cyclic in our lives, feelings that are given my own voice in the literary text under study..

The purpose of this Masters thesis is to accomplish an understanding for childrens librarians purchases of juvenile books. Two main questions are to be answered: - Which considerations do childrens librarians do when buying juvenile books and which goals and motives are behind their purchases? - What do childrens librarians think that their knowledge and competence consists of and how is that knowledge useful when buying juvenile books? To answer the questions qualitative interviews with five childrens librarians have been carried out. The material has been analyzed through a theoretical construction consisting of theories about collection development, book selection and quality judgments. The conception tacit knowledge silent knowledge from Michael Polanyi has also been used for interpretation.

The main purpose of this study was to establish to what extent undergraduate students use reference services, what knowledge they have about those services and what their views of them are.The survey took place at Lund University Library, UB1, the main library responsible for collections in social sciences, humanities, theology and law. A total of 476 undergraduate students were asked to fill in a questionnaire, 273 accepted. The study is quantitative and was carried out during the autumn semester, 1996.The results show that the service used most frequently by undergraduate students is the reference collection. The least used service is the Internet, more than 50 percent of the students never use Internet at the University Library. In general, students are very pleased with the service given by the reference librarians, and with the collection of reference books.
