Utvärdering av rörelsemönster hos öring (Salmo trutta) utifrån otolitmikrokemi
The classic view of trout (Salmo trutta) life history is that trout begins its life in freshwater, migrates to the ocean after about 1-4 years and then returns to freshwater to spawn. As trout fry have been caught at the mouth of the River Emån, near the Baltic Sea, researchers have speculated that some trout emigrate during their first year of life. The purpose of this study was to describe the variation in the length of time trout reside in freshwater before they migrate to the ocean for the first time. Another purpose was to investigate whether it was possible to discern where and how long the fish spent in freshwater and saltwater during different parts of their lives. Between 2007 and 2009, 23 adult trout were captured in the River Emån in southeastern Sweden.
Central Peripheries: speculation and strategy for a land less mentioned
As the contemporary discourse surrounding urbanism is almost exclusively focusing on aspects of density and traditional urban qualities, it entrenches notions of what constitutes a proper city and countryside. But beyond this urban-rural dichotomy is another highly contemporary landscape. A territory usually mentioned as sprawl, peri-urban, wasteland, edge city, etc. Although its existence is due to mobilization, telecommunications, globalization and other phenomena of modern life, it is a landscape without an own name or place in public awareness.This thesis provides a case study of how to map and intervene in such a landscape, specifically along the border between Malmö and Burlöv municipalities in southern Sweden. Its structure is composed of a sequence of three parts:1 Spatial Conditions:Divided up in the sections Network, Fringe and Void.
Short-term responses of the field layer vegetation in a south Swedish deciduous forest after establishment of wild boars (Sus scrofa)
Inside the south Swedish national park Dalby Söderskog, wild boars (Sus scrofa L.) have been visiting since 2010. The presence of wild boars has earlier been proven to
impact both soil and vegetation characteristics, both positively and negatively. Still, there is a lack of knowledge regarding the rooting effect on the vegetation in
deciduous forest within the native range. In this study, I have compared the field vegetation collected before and after the invasion of wild boars in 74 permanent experimental plots. More specifically, the study aimed to qualify the effect of wild boar rooting on cover ratio, species richness and species composition in a temperate
deciduous forest.
De första på plats: En fallstudie av entreprenörers resonerande vid etablering på en ung marknad
One of the areas in which current theory on entrepreneurship is ambiguous is in the explanation of how entrepreneurs act when entering a new market. One author that has attempted to contribute in this area is Saras D. Sarasvathy who has tried to explain the entrepreneurs reasoning through the theory of causation and effectuation. The former refers to a reasoning that takes the effect of an entrepreneurial action as given, while the latter looks upon the effects as uncertain, while only the means are given. With a foundation in this theory, Sarasvathy claims that when entrepreneurs enters a new market the level of environmental uncertainty is so high that reasoning based on causal relationships is rendered useless.
The effect of training on spontaneous blink rate in dogs
The spontaneous blink rate is found to be a non-invasive but functional, reliable and useful way to monitor central dopaminergic activity. Dopamine is associated with a range of functions such as reward, motivation and learning. It plays an important role in goal-directed behavior and in maintaining a behavior once a task is learned. As far as the author knows, there are today no publications that discuss the topic regarding the possible link between training and spontaneous blink rate in dogs. Therefore, eight privately owned dogs were included in this study to determine if there was a significant difference in the spontaneous blink rate before and after the process of learning a task.
attraktrivitet och regionplanering : Hur ska osby kunna ha en positiv ekonomisk tillväxt och befolkningsutveckling i region skåne?
AbstractAttractiveness may be defined by a variety of factors but you should see it in the public planning as it is to have a positive population growth and economic growth, through working with communications, service, housing, to name a few. This is done primarily through direct projects both within the municipality and through various partnerships between local and regional level. The progress we have seen in recent years has gone more towards a clear shell level, particularly a regional level where these have had a much greater freedom with clear geographical boundaries in between each other. Within these regions there are also clear regional groupings that have common interests and competing between each other. In my thesis, we have been distinguished including three levels of scale levels.
Cancersjuka patienters upplevelse av livskvalitet och välbefinnande i samband med yogautövning. : En deskriptiv kvalitativ studie med semistrukturerade intervjuer.
AbstractAim: The aim of this study was to describe cancer patients? experiences of quality of life and wellbeing in relation to yoga practice.Method: A descriptive qualitative study with semi structured interviews was carried out during the fall of 2009 at the University of Uppsala. Informants in the study were cancer patients who were participating in the yoga/psychotherapy group at the clinic of oncology at the Akademiska hospital in Uppsala.Result: Five out of six informants experienced that their quality of life and their wellbeing improved by practicing yoga. One informant had mixed feelings which were not due to the yoga practicing, but to the place where it was practiced. For her this place was associated with illness.
Kontrollerande aktieägare och företagsvärde : En empirisk studie av hur den kontrollerande aktieägarens kapitalandel respektive röstandel påverkar ett företags värde
Via semantisk analys har förekomst och variation av KRAFTmetaforer i två olika typer av texter jämförts. Hypotesen är att kognitiva neurala nätverk som ansvarar för den abstrakta tanken är tätt sammanbundna med kognitiva neurala nätverk som representerar känsloerfarenhet baserat på sensoriska upplevelser. Analysen utfördes på två olika typer av texter. Resultatet visar på signifikant skillnad i förekomsten av antalet metaforer i de olika texterna. Ett antagande för undersökningen var att självbiografiska texter är mer förankrade i känsloerfarenhet baserat på sensoriska upplevelser än vad argumenterande texter är.

The product is constructed by us, Patrik Svensson and Magnus Zetterqvist, for Christoffer Lindhe at Lindhextend AB. Christoffer has hired Martin Bergman at Smedjan 17 to make the design.
Återvinning av näringsämnen från hushållsspillvatten med omvänd osmos
Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.
Hur bemöts Kina i Afrika? : En mångdimensionell idealtypsanalys av Sydafrikas, Zambias och Zimbabwes bemötande av Kinas ökande ekonomiska intresse
The outset of this study is to contribute to the literature concerning China?s increasing economic interest to engage in the African context, its economies and resource abundandce. The overarching research problem is that the approaches held by the respective African state entities may facilitate increasing development gains for the recipient state of this economic interest in principle. To adress this research problem the study is undertaken by conducting a comparative case study where three cases/states, with presumably diverging economic and political status, are likely to effect their overall state approaches differently.Research questions, which are addressed by the creation of an idealtype analytic matrix, concern whether the states of South Africa, Zambia and Zimbabwe take on a more ?permissive? or ?restrictive? approach towards China?s economic interst and whether the approaches can be looked upon on both aggratege and case/area-specific levels.The main findings are that a clear tendency of the ?permissive approach? may be noted on a aggregate level for all cases.
Effect of insulin during oocyte maturation in vitro on bovine early embryo development : partially evaluated by novel fluorescent staining
Fertility is of central interest in the dairy production but has during the last decades declined. Increased milk yield has resulted in high pressure on the metabolism of the dairy cows that are supposed to manage the transition from dry cows to lactating cows within a few weeks around the parturition. Much indicate that metabolism and fertility are closely linked, with insulin playing a substantial part. There are many studies suggesting that the main part of gestation loss can be found during the early embryo development, a period which can be studied in vitro. The aim of this study was to test the effect of insulin during maturation in vitro and to evaluate two different fluorescent stainings on oocytes and embryos; a nuclear stain and a staining of apoptotic cells through the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL)-method.
Bovine cumulus-oocyte-complexes (n=991) were aspirated from abattoir-derived ovaries.
Nya Möjligheter för Kontroversiella Varumärken-En studie kring kontroversiella varumärkens framfart i sociala medier
As commonly known, Social Media is a rapidly growing area. Since consumers to a great extent are present in Social Media, this new internet environment is increasing in relevance for consumer marketing. For controversial brands that are regulated in conventional marketing channels Social Media is an extra ordinary marketing opportunity, since social media is a legal grey area. More and more controversial brands are taking advantage of this opportunity, but the effects of these marketing activities are fairly unknown. Therefore there is an interest in examining the controversial brands marketing progression in Social Media.
Plasmodiophora brassicae ? host and environment interactions
In this thesis, three separate experiments have been performed on different aspects of the interaction between the causal agent of clubroot, Plasmodiophora brassicae, and its hosts.
In the first experiment the pathotype of the P. brassicae single spore isolate, which is currently used to construct a reference genome, has been classified using the ECD bioassay. The disease severity of infected plants was scored according to two different scales and the pathotype was determined according to three previously published guidelines. The results were compared to previous published studies describing the e3 isolate.
The life cycle of P. brassicae is not well understood.
Analys av prispåverkande faktorer på bostadsrättsmarknaden i Uppsala
AimThe purpose of this study is to analyze factors that affect the price on tenant-owner apartments in the central parts of Uppsala. Special attention is put on analyzing how the monthly fee and the location affect the price. The hypotheses are that the monthly fee and the distance to the central part of the city have a negative effect on the price. A number of additional price affecting factors was taken in consideration during this study.MethodThis study is mainly based on data supplied to us by Mäklarstatistik. The supplied data consists of information about tenant-owner apartment sales in Uppsala during a year under 2008 and 2009.
