Det svenska vetenskapliga biblioteksväsendet under 1950-talet

After W.W. II the Social democratic government wanted to modernize and rationalize the Swedish society. The university system was reformed[INS: :INS] to support growth of industry and science. But the reform did not reach Swedish academic library system and it was not well organized. The aim of this thesis is to analyze the reaction of the Swedish academic libraries to the new era in the framework of ideological criticism.

Representationer av migranter inom biblioteks- och informationsvetenskaplig forskning : En textanalys utifrån kritiska ras- och vithetsstudier och intersektionell teori

The purpose of the essay has been to examine representations of immigrants in contemporary library and information science research in a Scandinavian context. By analyzing nine articles from the past decade we examine the perceptions that exist in the concepts of multiculturalism, culture, race, ethnicity, religion, gender and whiteness and what role and importance the library as a place is assigned in relation to immigrants as a user group. Our study consists of a qualitative text analysis, a critical oriented close reading method based on critical race and whiteness studies and intersectional theory. We have, with the help of Sara Ahmed´s theories of hegemonic whiteness, demonstrated how multiculturalism is partly presented as something desirable and good, partly as something potentially threatening.The discourse of multiculturalism can be said to express the notions of the other, which in the source material manifests itself by ascribing otherness to immigrants. We have, for example, examined how ethnical and cultural differences are highlighted by a separation of East and West, the library?s educational and assisting role in relation to immigrants as a user group as well as representations of whiteness, gender and clothes.

Fysikdiskursen på Komvux : Betydelsen av student-lärarinteraktioner

This study draws upon the framework for analyzing the discourse of a science classroom introduced by Mortimer and Scott (2003). It has been used for many studies before on high school youths, but never on adults. Therefore, this study focuses on the interaction between teacher and students in an adult education on high school level in physics, and how students can change the classroom discourse. Observations took place in two different schools for adults, in four different teaching groups. The result was analyzed by pattern of interactions, communicative approach, teaching purpose, type of student questions and their effect on the classroom discourse.

Willingness to pay for improved maize seeds among smallholder farmers : a study of the input factor market in Kenya

Kenya is considered to be a developing country. This means that basic needs such as nutrition are not met for an extended period of time (www, Sida 1, 2012). Approximately half of the population is living under the poverty line (www, CIA 1, 2012). Agriculture is the largest sector in the country, employing 75% of the population. These are thereby directly dependent on the sufficiency of outputs received.

Kloning av möjlig promotorsekvens uppströms kloritdismutas i Ideonella dechloratans.

Perchlorate and chlorate are naturally occurring in the atmosphere, from here it sediments into groundwater and soil. The pollution is increased by discharges of perchlorate and chlorate from agriculture and paper mills. Bacteria capable of reducing perchlorate and chlorate to chloride and oxygen can be used to get rid of these contaminants. However an anaerobic environment needs to be sustained in order for this reaction to be used. For this reduction to work in an aerobic environment as well, a greater knowledge of the reducing enzymes, regulating factors and their corresponding genes is needed.

Läraren och tjänstemannauppdraget : En studie om lärarstudenters syn på sina framtida tjänstemannauppdrag

The aim of this essay is to examine how future upper secondary school teachers within social science comprehends their future proffessional role. The aim is also to see whether the education is of importance to their suspension for their future professional role. Focus will especially be on the teachers civil servant role, where the aim is to see how their identification suspends to the governmental expectations on their future civil servant misson. The essay is based on a qualitative method, which is focused conversational interviews.The result indicates that future upper secondary school teachers within social science, who are about to finish their education, have a somewhat deeper sense of identification with the teachers civil servant mission compared to those in the beginning of their education. The result also indicates that the future upper secondary school teachers identification are in line with the governmental expectations on their civil servant mission.

Frihandel mot miljön? - en analys av GATT artikel XX (b) med utgångspunkt från en ny WTO-rapport

Förhållandet mellan handel och miljö är kontroversiellt inom The World Trade Organization (WTO) och arbetet på området präglas av motsättningar. WTO-kritiker har pekat på ett antal tvister inom WTO där WTO:s tvistlösningsorgan beslutat till nackdel för det land som har infört handelshindrande åtgärder för att skydda miljön. Utfallet kan tolkas som att miljöintresset förlorade mot handelsintresset. Det är dock tveksamt om man kan dra några slutsatser enbart genom att se till utfallet. Denna uppsats syftar till att bringa mera klarhet i hur WTO-reglerna balanserar frihandelsintresset mot miljöintresset.

Markberedningsresultat och plantbildning med såddaggregaten Humax 2-4 och KSM-såddskopa

Fördelarna med skogssådd är bland annat att de kan ge stamtäta bestånd med potential att producera träd med bra vedegenskaper och bättre utvecklade rotsystem samt att sådder har en högre biomassaproduktion per ytenhet jämfört med planteringar. Nackdelar som kan nämnas är att de ofta täta förbanden ger ökade kostnader vid eventuella röjningar och att föryngringsresultatet är mera osäkert för sådd än för plantering.Mekaniseringen av skogssådden startade under 1970-talet. Humax och KSM är två kranspetsmonterade aggregat för skogssådd. De har utvecklats för att användas på marker med svår ytstruktur där dragna såddaggregat som harv och högläggare har svårigheter att skapa tillräckligt mycket lämplig såddbädd på grund av att aggregatet inte kommer ner mellan hindren eller att basmaskinen inte klarat av att köra över hela arealen. Fördelen med KSM och Humax är att aggregaten är kranspetsmonterade vilket gör att föraren väljer var aggregatet skall markbereda och på det viset kan markberedningen göras mellan hindren samt att kranarmens räckvidd gör att basmaskinen inte behöver köra över hela arealen som skall markberedas.

Hänsyn till mark och vatten vid slutavverkning : en fältstudie på känsliga marker

The purpose of this study is to investigate if there is enough consideration taken to sensitive forest areas close to water or wetlands during clear cutting assignments, and to estimate the extent of damage made by forestry machines used at that time. A field and literature study is used to show how to improve and prevent the damage made in the wake of the machines. This study is made for Sydved, and shall culminate in a policy to prevent ground damage during their clear cutting assignments. The areas which were part of the field studies were clearcuttings on fine grained soil close to water and wetlands. The purpose was to find out if the water had been affected, what had been done to prevent ground damages and what more could have been done. The results of the field studies show that more work needs to be done to reach up to expectations. More information about the assignment area, better planning of sensitive regions, and strengthening of the main haul roads with brush are some of the improvements that can be done. There is also a need for more exact guidelines, follow-ups and education for everyone involved to have the same goals and understanding to prevent ground damage..

Bland kranier, modeller och elektronmikroskop : Ett ordnings- och förteckningsarbete på Museum Gustavianum, föremålsmagasin Husbyborg, av handlingar rörande utgrävningen i Asine

This paper is an account of the inventory I've made of documents in the archive at Museum Gustavianum, Collections storage Husbyborg, relating to the excavations in Asine, Greece, in the 1920s. The aim of this inventory has been to establish which of the documents in the Husbyborg archives that belong to the department of Classical Studies at Uppsala University. Documents belonging to other archives have been found alongside the one mentioned above and those are the Original documentation (loan from Carolina) and the personal archive of Professor Axel W. Persson. The documents have been arranged according to the General Archive Scheme (Allmänna arkivschemat) seeing that the department of Classical Studies already had a series named Documents relating to the departments archeological collections, and the inventory I've made will be incorporated with that.

Lilaköttig taggsvamp, Sárcodon fuligíneovioláceus : miljökrav i Sverige och en analys av vad som styr artens etablering

Burnt Spine-cap Sárcodon fuligíneovioláceus are one the most endangered mycorrhizal fungal species in Europe. They have their main distribution in Sweden. It form mycorrhiza with pine and dependent on limestone, which makes it connected to a rare environment. It has therefore been important to study the ecology of it further and to recognise the requirement it has on the environment more accurate and what it need to establish in a new area. In this study, 31 of 34 known sites in Sweden was visited and studied in field and their history analysed through aerial photographs.

Dimensionering av monopåle för grundläggning av vindkraftverk till havs: Baserat på finita elementanalyser

Vindkraft är en förnyelsebar och utsläppsfri naturresurs. En fortsatt global utbyggnad av land- och havsbaserad vindkraft är att vänta. Fördelar med vindkraft till havs är bättre vindförhållanden och lägre krav på hänsyn till landskapsbild och närboende, vilket medför att vindkraftverken kan byggas större och därmed kan vinden utnyttjas mer effektivt. För havsbaserade vindparker krävs en lösning för grundläggning som är rationell och anpassningsbar. Vid dimensionering av konstruktioner till havs är det viktigt att ta hänsyn till den cykliska belastningen från vind och vågor konstruktionen utsätts för.
