Klassifikationssystem för en medicinhistorisk samling en jämförande studie av SAB och NLM

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.

Energieffektivisering i ett reningsverk för skogsindustriellt avloppsvatten genom förfällning av extraktivämnen

Pulp- and papermills expend vast amounts of water in order to produce pulp, paper and cardboard. Hence, they alsocreate vast amounts of waste water which has to be cleaned before it can be released into the receiving body of water. Insuch a wastewater treatment plant, tremendous amounts of energy are expended by the aeration in the biologicalcleaning process. This aeration is necessary to supply the microorganisms that shall decompose organic material withoxygen, which they need for their metabolism. The transfer of oxygen from the gas phase to the liquid phase isprimarily inhibited by surface-active substances in the waste water like resin acids or fatty acids.

E-böcker på högskole- och universitetsbibliotek ? En studie kring det digitala förvärvet

This study aims to find out how the selection and acquisitions of ebooks made by university libraries is affected by vendors terms of sale. The empirical data is based on interviews with libraries working with selection and acquisition of ebooks. The interviews points out, according to Evans? model of collection development, that the collection development doesn´t work the same way with printed and electronic books. The study also finds out that the complexity of the ebook marketplace implies the application of new method of ebook selection, by libraries..

Skillnader i kungsörnens (Aquila chrysaetos) flyttningsmönster beroende på ålder och klimatfaktorer : En studie för skyddet av kungsörn

This study examines the factors that influence the seasonal movements of Golden Eagles (Aquila chrysaetos), and can thus provide important information that helps to improve the protection of the species. There were two main purposes of this study. First, I wanted to analyze the difference between preferences of juvenile and adult Golden Eagles in their choice of southern or northern hibernation areas. Do younger eagles prefer moving longer distance to southern areas of Sweden? Second, I wanted to investigate how the climate influenced the choice of date of migration in the fall.

Reducering av produktionstryck i A-linan : Förflyttning av produkt

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.

Måltiden som lärandesituation i förskolan : en kvalitativ studie om pedagogers syn på barns övergripande och hälsofrämjande lärande i förskolan genom den pedagogiska måltiden

The purpose of my study has been to find out how four preschool teachers at four different preschools looks at the pedagogical meal from a health and overall learning perspective. I also want to examine how, through the pedagogical meal the preschool teacher works to promote children´s learning and give them an understanding of need to safeguard their health. To achieve my aim I set the following questions;What are the different types of learning preschool teachers believe that children can acquire the basis of the pedagogic meal?How do preschool teachers describe their work from the pedagogical meal to benefit children´s overall learning?How do preschool teachers describe their work at the pedagogical meal for the children to gain an understanding of their health?The study is based on a qualitative method with interviews and observations, triangulation. The theoretical approach to this study is based on the socio-cultural perspective to learning and development.

Hylasmotivet hos Apollonios Rhodios och Theokritos

An increasing global population and a worldwide growing urbanization has raised the questionabout the future food security in cities all over the world. Peak-oil limits the access to cheap fossilfuels which threatens the global food-supply chain. This has resulted in a larger awareness anddiscussion related to urban agriculture. Growing crops and keeping animals within the city-borderscould be one way of creating a more robust and sustainable food supply for city dwellers. However,to enable an expansion of the urban agriculture many theorists argue that policies and institutionalstructures that supports and promotes city farming have to be developed.

Ohållbar marknadskommunikation av seriösa hållbarhetsaktörer: en fallstudie av H&M och Max

Problem: Företag ägnar sig åt ett seriöst hållbarhetsarbete, men det finns anledning att tro att detta inte speglas i deras marknadskommunikation. Förändringar i marknadskommunikation tenderar att vara konservativa, då företag väntar på en indikation från marknaden för ökat intresse av hållbara produkter.Syfte: Huvudsyftet med arbetet är att undersöka huruvida företag inom ?fast fashion?- och ?fast food?-industrierna som gör ett gediget hållbarhetsarbete också använder en marknadskommunikation som är ohållbar. Som en del av detta arbete kommer en grundläggande definition av ohållbar marknadskommunikation att konstrueras genom teoristudier.Metod: En kvalitativ undersökning har använts, då en fallstudie med bildanalys har genomförts, med empirisk data hämtad från företagens marknadskommunikation.Teori: Den teoretiska referensramen grundar sig i teorier kring marknadskommunikation, hållbarhetsaspekter och konsumtionssamhällets konstruktion.Resultat: Det empiriska materialet redovisas genom fallstudieberättelse, baserad på bildanalysen av marknadskommunikationsmaterial som utförts och den analysmodell som har konstruerats.Analys: Empiriska data som insamlats har jämförts med de teorier som vi använt oss av i den teoretiska referensramen. Resultaten har analyserats för att hitta övergripande likheter inom företagens marknadskommunikationSlutsats: Företag inom ?fast fashion?- och ?fast food?-industrierna som arbetar seriöst med hållbarhetsarbete kan också använda en ohållbar marknadskommunikation enligt den definition som har konstruerats..

Tillfällen då hemodialyspatienter anser det vara svårast att undvika vätskeintag : En empirisk studie

The aim of this study was to investigate which situations haemodialysis patients consider as the hardest for avoiding fluid intake. The data collection was performed with a questionnaire which was distributed to haemodialysis patients who fulfilled the inclusioncriteria. Of 158 haemodialysis patients 103 haemodialysis patients chose to participate in the study. The participants were chosen from different dialysis centres (n=12) in north and south of sweden, excluding the middle of Sweden. The questionnaire that was given out consisted of 32 situations, the response format included nine alternatives, that included different kind of difficultes.

Kvalitetsbegrepp och tv-spelsbestånd - En fallstudie av tv-spelsverksamheten på Malmö stadsbibliotek

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.

Förvärvsprocesser - vad köper biblioteken in och varför? En undersökning av förvärv gällande skönlitteratur på Lunds huvudbibliotek och fyra stadsdelsbibliotek

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.

Low Temperature Waste Heat Solutions : with proposals for energy technological actions based on Scania?s building 64

The report comprises two separate parts:part 1:  Temperature needs for district heating in the paint shop for axles in building 210part 2:  Energy and low temperature waste heat solutions in heating and cooling systems for   building 64 with surroundingsThe paint shop for axles in part 1 has air quality requirements in places for coating of axles. Toachieve desired air properties there are different process ventilation systems, which consist ofventilation coils for heating and cooling, plus air humidifier. The ventilations coils for heating usedistrict heating. Today the ventilation coils use water of 100°C to achieve necessary air demands inthe coating boxes. This part of the report investigates whether the existing system would achievethe air requirements with a water temperature of 75°C instead of 100°C in the ventilation coilsduring the coldest parts of the year.

Fosforavskiljning i reaktiva filter vid småskalig avloppsrening

An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.

Evaluation of specificity of a walnut antiserum and detection of English walnut (Juglans regia) in food with ELISA and Real-Time PCR

Nuts of all kinds are common ingredients in food. For nut allergy sufferers the frequent use of nuts cause problems and "hidden" nuts in food products may elicit allergic reaction when such foods are consumed. Methods for detecting and quantifying walnut (and other nuts) with high sensitivity and specificity are therefore very important.The objective of this project was to verify the specificity of a rabbit antiserum against walnut with immunodiffusion and to determine the size of the dominant walnut antigens with Western blotting. In addition, a commercial sandwich ELISA for walnut quantification was validated and compared with a qualitative real-time PCR.The rabbit antiserum proved to be less specific but after absorption with cross-reacting nuts and seeds it showed high specificity. The ELISA kit reacted, except for walnut, with pecan and slightly with other nuts and seeds tested.

Egenkontroll i livsmedelsbranschen utifrån verksamheternas perspektiv : en kvalitativ studie

Verksamhetsutövare inom livsmedelsbranschen har ett ansvarar för att den mat som producerats är säker. År 2009 gjordes ändringar i den svenska livsmedelslagen där bland annat kraven försvann på att verksamhetsutövare måste ha skriftliga rutiner och dokumentation (Lindblad, Westöö, Lindqvist, Hjertqvist & Andersson, 2009). Oavsett om verksamhetsutövarna har skriftliga rutiner och dokumentation eller inte måste de kunna bevisa att de har tillräcklig kunskap för att arbeta med livsmedelshantering. Genom ett fungerande system för egenkontroll, alltså en egen kontroll av verksamheten, skapas säkra livsmedel och risken för matförgiftning minskar (Israelsson, 2006). Syftet med denna studie är att undersöka verksamhetsutövarna inom livsmedelsbranschens uppfattning om egenkontroll.
