A porcine type 1 Diabetes Mellitus model, for non-invasive in vivo imaging of the glucagon-like peptide-1 receptor in the pancreas, using [68Ga]Ga-DO3A-VS-Cys40-conjugated synthetic exendin-4 in PET-CT

Diabetes mellitus is a rising epidemic throughout the world and there is currently great interest in quantifying the beta-cell mass (BCM) in vivo non-invasively. In the present experiment, the feasibility of in vivo imaging of the glucagon-like peptide-1 receptor (GLP-1R) in beta-cells was examined, using the positron emission tomography (PET) tracer [68Ga]Ga-DO3A-VS-Cys40-exendin-4 as a marker, in native pancreatic beta-cells of a porcine diabetic animal model and healthy controls. Eight Swedish high-health domestic pigs were randomly assigned to be either controls or made diabetic using streptozotocin (STZ). The experiment proceeded during eight weeks, starting with an acclimatisation period. Once the pigs had been socialised they underwent surgery for the insertion of a jugular vein catheter, allowing induction of diabetes with STZ, intravenous (i.v.) injections and stress-free blood sampling. Development of diabetes was confirmed by clinical examinations, blood glucose values and insulin-staining of pancreatic sections post mortem. The diabetic pigs were insulin treated and responded well.

Sverigedemokraterna i skolan : En undersökning om mellanstadielärares förhållningssätt till Sverigedemokraterna i samhällskunskapsundervisningen

A majority of conducted studies connected to democratic socialization and the party-political education has primary affected students in higher education. In this study I intend to find out how primary school teachers handle controversial issues in social science connected to the political parties.  The Swedish Democrats are by many perceived as a controversial party and while the school?s mission is to educate students to think independently another mission implies that certain views are not to be uttered if they stand contrary to the basic democratic values. The aim of this study is to obtain knowledge in and about the teachers view on the dilemma between the more nurturing assignment versus the knowledge assignment and in connection to this how they approach the Swedish Democrats in the classroom. For further immersion the research treats the following questions:  How do teachers view their own role as intermediaries in democratic education?  How to teachers portray the Swedish democrats in education?The survey was conducted by using qualitative interviews.

Restoring biodiversity in degraded secondary rain forest in Sabah, Malaysia : natural regeneration of trees after restoration treatments

Many tropical rain forests has been lost or degraded as a result of human activities and environmental factors. Since the level of biodiversity is high in the tropics, maintaining these areas is of great importance. Forests like these are often assumed to benefit from forest restoration and rehabilitation. The INIKEA project area in Eastern Sabah, Malaysian Borneo, aims to improve biodiversity and/or species richness in the degraded forest through enrichment planting with indigenous species. The objective of this thesis was to evaluate how different treatments (liberation, gap-cluster planting and line planting) affect the biodiversity of natural regeneration in different forest types in the Rain forest Restoration Experiment, located in the INIKEA project area.

Upplevelsebaserat lärande i dagens gymnasieskola - en studie om filmmediet som hjälpmedel i musikundervisningen

Title: Experiential learning in the upper secondary school ? a study of film as a method in music education. Today the school competes foremost with TV and the computer regarding the spreading of knowledge. I believe that it is of great importance for the school to move with the developments of society in order to, to a greater extent, reach and motivate pupils. My degree thesis is about how you, as a teacher, can use experiential learning in music teaching in the upper secondary school.

Lärares inställning till genus och könsroller : en attitydundersökning

AbstractA Vindication of the Rights of Woman was written by Mary Wollstonecraft. It was published in 1792 and as the titel reveals it dicusses what kind of rights women ought to have. Several authors, who have argued that women should not have the same rights as men, are mentioned in the book. One of them is Rousseau. His thoughts about different education for girls and boys are shown in Émile.

Library anxiety: en undersökning av psykologiska aspekter kring studenters upplevelser av sitt universitetsbibliotek

This essay investigates the psychological aspects in students' experiences of their university library and the information seeking process. Focus of the investigation is library anxiety, a kind of fear towards the university library with cognitive, affective and behavioural aspects. Twenty students at Uppsala university, who was about to conclude or recently have concluded an academic essay, were interviewed about their experiences of the university library, Carolina Rediviva. Five respondents stated experiences of fear, anxiety and apprehension in the library and it is on these informants that the greater part of the analysis and discussion draws. The essay suggests a model of library anxiety where outer environmental aspects of the library, such as the library environment, roles and routines of the library and library staff, interacts with inner personal aspects of the individual such as personal experiences, intellectual capacity and sensitivity to stress and anxiety.

Sinnesmarknadsföring : En observationsstudie över kundbeteendet på OnOff i Kalmar

Vi valde att skriva vår C-uppsats om sinnesmarknadsföring och hur detta påverkade kundernasagerande i butiken. Vi såg detta ämne som väldigt intressant och något som låg rätt i tiden. Attsinnesmarknadsföring sedan är ett nytt ämne vilket är hyfsat outforskat gjorde oss ännu merintresserade inom detta område. När vi undersökte detta ämnet närmare framgick det att vi intekunde se några direkta undersökningar om hur sinnesmarknadsföring påverkade kunderna utanvi hittade endast litteratur där författarna förklarade hur det fungerade. För att se om denna nyastrategi inom marknadsföring påverkade kunderna valde vi att genomföra ett experiment påOnOff i Kalmar för att sedan utföra observationer på de kunder som gick in i butiken.

"Man måste gå på magkänsla" : en kvalitativ studie om hur lärare och elever ser på Internet i undervisningen och skolarbetet.

Syftet med denna kvalitativa studie är att undersöka vilken syn lärare och elever har påInternet som arbetsverktyg i undervisningen och skolarbetet. För att ta reda på detta har vigenomfört kvalitativa intervjuer med fyra gymnasielärare, varav två arbetar på en kommunalskola och två arbetar på ett friskolegymnasium. Dessutom har vi genomfört kvantitativaenkätundersökningar med 100 gymnasieelever, 50 på vardera skola. Vår undersökning visaratt lärarna och eleverna är positivt inställda till Internet i undervisningen, men den påvisaräven att eleverna, särskilt de på friskolan, har en tendens att se Internet som sin enda källa,vilket är något som bekymrar lärarna. De menar därtill att källkritik är något man som läraremåste gå igenom kontinuerligt för att få eleverna att förstå innebörden av det och hur viktigtdet är.

Jämförelse av icke-kryptografiska hashfunktionerför användning i hashtabeller

This report examines some common or otherwise interestingnon-cryptographic hash functions with respect to the number of collisions when used in hash tables for different types of hashkeys. The report answers which of the examined hash functions can be seen as the best performing for the chosen hashkeys. To compare the different hash functions, an experiment which studies avalanche effect behaviour is carried out. The experiments also calculate the fraction of colliding hashkeys, and the distribution of hashkeys in hash tables is studied using Karl Pearson?schi-squared test.

Fermentation of lignocellulosic material by the alternative industrial ethanol yeast Dekkera bruxellensis

Bioethanol is one alternative energy fuel that can be produced from different types of biomass. Second generation bioethanol comes from fermentation of lignocellulosic material and can be seen as a more environmental friendly alternative as e.g. forest residues and agricultural by-products are used. To be able to use lignocellulosic biomass in ethanol production, it has to be subjected to different treatments first. In this study, aspen sawdust was used as lignocellulosic material.

How Does Ego Depletion Affect Moral Judgments and Pro-social Decisions?

BACKGROUND: Today?s societal changes, including high rate of change and increasing information flows, are increasing the demand on the individual mental capacity. It becomes increasingly difficult to analytically process all the different dilemmas and everyday decisions as individuals have a limited mental capacity available to make these decisions. Thus, it has been suggested that ego-depleted relies more heavily on intuition, which is less burdensome, when making decision. However little is known about to what extent intuitive decisions differ from analytic.

Arbeta med åtgärdsprogram : Två lärares uppfattningar om arbetet med åtgärdsprogram

The aim of this study is to describe the variation in two teachers perceptions of their work with individual developments. The study begins with a review of the Swedish National Agency for Education?s guidelines for working with individual developments. With this I want to give the reader an insight into the teachers working conditions and the responsibilities the school authorities have against their students. Using phenomenography, I have examined the differences between two mathematic teacher?s perceptions in working with individual developments for student?s in need of special education.   My questions are: How do mathemathic teachers perceive their work with individual developments? What support and what information do the teacher?s feel that they have been given in order to use individual developments as a tool? How do the teachers perceive that their work situation has influenced their work with individual developments? The two teachers I have interviewed showed different perceptions both in how they understood the guidelines for working with individual developments and how they chose to work with them.

En gymnasielärares erfarenheter av läs- och skrivsvårigheter

AbstractThe purpose of this essay is to increase the knowledge of which strategies students with reading and writing disabilities or dyslexia use to learn in secondary school. The study aims to examine the following questions:Which coping strategies do students with reading and writing disabilities use in their studies?How can remedial teachers support students with reading and writing disabilities in their learning process?The study consists of two interviews with a total of three hours recorded material made with a secondary school teacher who teaches Swedish and English. The teacher has experiences of reading and writing disabilities herself but also from teaching students with dyslexia. The interviews are constructed into a lifestory describing experiences of reading and writing disabilities in school, during teacher training and as a teacher.

Hunden som resurs : En studie om hunden som ett pedagogiskt hjälpmedel

This study shows how two different schools use dogs as a method of education. The purpose was to find out what kind of pedagogical thoughts my informants have about children' slearning in their connection with dogs, and in which way the interaction between the children and the dogs could affect the learning ability. I also wanted to find out what kind of possibilities and restrictions the dogs could give to the education according to my informants but also to find out how the projects were financed. To be able to answer these questions I put together a qualitative study, I had four interviews with people that were involved in the projects in one way or the other. To analyse the empirical material I looked up different theories about teaching, communication, interaction and motivation.My results showed that both schools have applied the method of ?teaching dogs? as a form of resource for students with special needs.

The effect of domestication on insect resistance in cotton : bioassays with the insect herbivores Spodoptera littoralis and Agriotes spp.

A plant's defensive ability against herbivore attack can be influenced by many different factors, one of them being domestication. During human selection to improve the yield of plants, the resistance against herbivore attack can have been lowered, due to a trade-off for use of resources between these traits in the plants. In this thesis I investigated the effect of domestication on resistance against herbivorous insects in cotton plants. I used different varieties and species of wild and domesticated cotton in three different experiments. A feeding assay was conducted, the mortality, development time and pupal weight of larvae of the Egyptian cotton leaf worm Spodoptera littoralis was studied. In a second experiment the preference of the root-feeding beetle Agriotes spp.
