Effekter av specifika näringsämnen vid osteoartrit hos hundar: verkningsmekanismer för omega-3-fettsyror, 'green-lipped mussel' och glukosamin kombinerat med kondroitinsulfat

Osteoartrit är en vanligt förkommande degenerativ ledsjukdom hos våra hundar som orsakar smärta, stelhet och minskad rörlighet hos drabbade individer. Ledbrosket bryts ned och detta följs av en inflammatorisk process som ytterligare driver på utvecklingen. De bakomliggande orsakerna varierar men kan t ex vara felställning av ben som ger onormalt slitage eller övervikt som ökar den mekaniska påfrestningen på brosket vilket initierar nedbrytningsprocessen. De genetiska förutsättningarna har stor betydelse för sjukdomsutvecklingen. Sjukdomen är kronisk och progressiv.

Bottensubstratets inverkan på föryngring av Flodpärlmussla

The freshwater pearl mussel (Margaritifera margaritifera) is threatened throughout its range. There has been a substantial decline of the species and one major reason is habitat degradation. We investigated how the substrate composition of the bottom floor affects the regeneration of the mussel by analyzing data from the Västerbotten County Board?s inventory of the freshwater pearl mussel. The results implied that fine material such as fine sediment and sand might be detrimental to regeneration whereas gravel and boulders and in particular stone seem to be beneficial.

Freshwater pearl mussel as indicators of Swedish streams - a comparison between freshwater pearl mussel and biological quality elements

The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity. Moreover, due to the species complex life cycle, including a larval stage on the gills of salmon and trout, and sensitivity of early life stages, regeneration is often used as an indicator. The freshwater pearl mussel is also used in the expert judgement of status classification of benthic invertebrates according to the European Water Framework Directive. The purpose of this study was to gain a deeper understanding of the freshwater pearl mussel as an indicator for Swedish streams. It was made with two types of association analyses.

Flodpärlmusslans status i Laxtjärnbäcken : Effekter på flodpärlmusslan av sedimentbelastning och förekomst av bäckröding

The aim of this present study was to determine and evaluate whether the presence of brooktrout (Salvelinus fontinalis) and sediment load may be a threat against the reproduction anddistribution of freshwater pearl mussel (Margaritifera margaritifera) in a creek located innorthern Sweden. Freshwater pearl mussel is an endangered species and is dependent ofbrown trout (Salmo trutta) to reproduce. Therefore there are concerns of indirect effects onthe population of pearl mussel by competition between brown trout and brook trout. Ditchesfrom a nearby gravel road have been fixed to lower the sediment load into the creek. I tried toevaluate this action plan.

Grön marknadsföring : En guide till grön framgång

The purpose of this thesis is to analyze green marketing and green brand building from a managerial perspective, with the intention to create an implementation guide for companies in the Swedish consumer market.  The essay is based on a qualitative approach with a mixture of inductive and deductive elements. We have interviewed five people with close links to green marketing. We have during the study identified a number of touch points to be particularly important in the process of incorporating green marketing. These findings are presented in full in chapter five. We have found that the framework of green marketing is established during the company?s choice of green strategy.

Habitatpreferenser hos tjockskalig målarmussla (Unio crassus) med avseende på vattendjup och beskuggning.

The thick-shelled river mussel (Unio crassus) is a red listed species classified as Endangered (EN) and is also considered within the Habitats Directive. The distribution in Sweden is fragmented and it is mostly occurring in the south eastern parts. We investigated the presence of Unio crassus in a section of the stream Storån, Östergötland County, from Falerum to the inflow into Lake Åkervristen. The environmental parameters investigated were water depth, bottom substrate, shading, water velocity and the slope over the water surface. In this thesis I have focused mainly on water depth and shading, comparing sites with and without mussels.

Bottensedimentets betydelse för flodpärlmusslans föryngring ? en metodutveckling

The freshwater pearl mussel Margaritifera margaritifera is an endangered species. To survive, the young mussels demand a fairly coarse bottom material containing an appropriate quantity of organic substrate to survive without suffocating. In order to estimate if a bottom is suitable for juvenile mussels, samples of the sediment are needed. To obtain samples a sampling device called the Mulv collector has been developed within this project. Bottom samples were collected from 18 stations in 4 south Swedish streams, Vramsån, Kling-storpsbäcken, Brönnestadsån and Bräkneån.

Green IS ? a Systematic Literature Review

This thesis provides a systematic literature review of a selection among current papers andarticles on Green Information Systems (IS). The main focus is on the current state of Green ISin academic research. This study aims at gaining a deeper understanding and a clearer view ofthe state-of-the-art of IS for environmental sustainability research, with the goal of clarifyingthe diffuse idea of what Green IT/IS is, and what differentiates Green IS from Green IT.To support the objective of this study, the articles selected for data analysis were collected byusing a systematic literature review as research and analytical method. Within the thesis, adescriptive angle with an interpretative character is used to analyse the data extracted.A theoretical framework based on concepts from sustainability, Green IS and Green IT isemployed in order to analyse and compare terminologies and frameworks used in the studiedarticles. Furthermore, the different dimensions of sustainability and the various terms used todescribe Green IS are analysed comparatively.The result and analysis are discussed in a conclusion confirming the on-going ambiguity ofthe terms Green IT and Green IS and the transformative power of IS.

Gröna tak som del i ett hållbart stadsbyggande

Green roofs have seen a revival in the society of today. They provide many functions of which both society as a whole and the individual can take part. In particular extensive green roofs, that requires little or even zero maintenance, provides very valuable functions. Green roofs affect our environment and our economy in a positive manner as well as the physical expression of buildings. In this bachelor thesis the impact of green roofs on society has been examined throughout literature studies. The result as a compilation of contemporary research in this field is presented together with a discussion about the use of green roofs in general. The two major arguments for an extended use of green roofs are, the high stormwater retention capacity and the cost-benefits seen over time compared to a conventional roof.

Detailed proposal over certain green objects such as parks and squares..

Inventering av flodpärlmussla i Fylleån norr om Gyltigesjön

Freshwater environments are threatened worldwide, of which many of the species associatedwith freshwater. In 2014, 243 freshwater mussels were on the international Red List. One ofthem is the freshwater pearl mussel, Margaritifera margaritifera, which because of itscomplex life cycle can be counted as an indicator of whether a stream is worth protecting. It's since the early 1900's in decline throughout their range. Sweden is counted as a core area which is why we have not only a national but an international responsibility to conserve the species.

Grönskan i Staden : grönstrukturens utveckling, funktioner & innehåll

The report by Boverket (2004), Hållbara städer och tätorter i Sverige - ett förslag till strategi says that large and somewhat intact green areas are better than severalsmall. Linking rural natural areas with the city's green areas, improves the opportunities for recreation and biodiversity (Boverket 2004). To create this, there isneed for a green structure in the city and its surroundings. But how to create this structure and what are the problems with the green areas in the city today? Thescenario that more and more people choose to settle in urban areas is a trend which not appears to decline, and at the same time our green spaces in cities and ruralareas decreases (Boverket 2007).

Valuing Green: A Qualitative Study on the Priorities of Values, Personal Norms and Identity for Green Consumer Products

The purpose of this thesis is to contribute to a further understanding of the complexity in green consumer behaviour by examining how and why individuals priorities values, personal norms and identity in green consumer behaviour. The thesis employs a qualitative approach with an abductive strategy. The empirical data was produced through in-depth interviews with green consumers. Based upon the empirical findings and theoretical concepts, a conceptual model was introduced to illustrate how consumers prioritise between several values when assessing green products. The prioritisation is dependent on internalised values as well as the product function and the need that the consumer seeks fulfilled.

Påverkande faktorer vid valet mellan vanlig el och grön el - en studie av hushåll i Göteborgsområdet

To be able to hinder the global warming the emissions of greenhouse gases, carbon dioxide foremost, must decrease. By switching to green electricity, it is possible to reduce the emissions from electricity producing sources.In 1999, Swedenergy conducted a study about whether or not Swedish households would consider buying green electricity. According to the study, about 75 percent were willing to buy green electricity. 40 percent of these were prepared to pay a premium for green electricity. However, according to the results from the study, only one percent actually bought green electricity, and since 1999, this proportion has merely increased slightly.
