Vindkraftens påverkan på sin omgivning : En fallstudie

Purpose of this thesis is to study the impact of wind turbines on their surroundings. It also aims to analyze how the communication looks between the authorities, the planner and local residents prior to the establishment of wind turbines in Lännäs/Odensbacken in Örebro, where three wind turbines set up in a group.The results of this survey show that the participants experience themselves not as especially disturbed of the turbines in the form of large noise, shadows, and sleep disturbance indoors and outdoors. Participants felt that no change had taken place on the natural environment (52%) since the turbines became operational. It was 49% of participants had got no information about the establishment of Örebro Municipality, Örebro County Administrative Board or Wind Power Company. Scientists/­experts had the highest confidence of 86%, politicians and the media/journalists had least confidence.

Möjligheter och problem med organiserat avelsarbete inom renskötseln

The reindeer are kept in extensive pasture systems where the conditions are similar to thosefor wild reindeer. Since the reindeer have special demands on their pasture, it is difficult tokeep them in intensive production systems where they cannot graze selectively. Too manyreindeer on a small area will also facilitate spread of diseases. A selection program forreindeer needs special qualifications according to several different reasons. The purpose withthis literature review is to summarize the factors needed for a reindeer selection program andthe problems and possibilities included.Reindeer grazing right has a special meaning to the Sami and are reserved for them accordingto immemorial rights.

Smärtlindring till papegojfåglar

Det är svårt att upptäcka smärta hos fåglar samt se om den smärtlindring som administreras ger någon effekt. Fåglar kan likt andra djur inte tala om var de har ont någonstans och hur stark smärtan är. Det är svårt att mäta smärta objektivt hos dem, vilket gör det komplicerat att ställa upp vetenskapliga försök. Metoder som kan användas för att bedöma smärta är bland annat att titta på förändringar i beteenden och fysiologi hos skadade djur eller att mäta smärtan objektivt med olika typer av apparater. Fåglar känner smärta och behöver därmed smärtlindring i precis samma situationer som däggdjur. Opioider, NSAID-preparat, lokalanestetika, alfa2-agonister och kortikosteroider används alla som smärtlindring till såväl fåglar som däggdjur.

En studie av viltets påverkan på Skogssällskapets fastighet i Selesjö

This degree project investigates how elk, roe deer, red deer and fallow deer can affect an estate in Östergötland. The inventories performed within this project, were completed on an estate in Selesjö, northern Östergötland. This property is used to demonstrate wildlife management. The methods used in this study were originally developed for areas larger than individual properties. Three inventories were completed in the study. These included the recording of the number of droppings and the amount of eaten pasturage, as well as the level of damage on young trees.

Perfluoroalkyl substances in Arctic birds : a comparison between glaucous gulls and black guillemots from Svalbard

Perfluoroalkyl substances (PFASs) are ubiquitous in the environment today and they have been detected even in remote areas such as the Arctic. PFASs can be transported by the atmosphere and ocean currents but the transport mechanism is not fully understood. PFASs may be harmful to organisms due to their persistence in the environment, bio-accumulation potential and toxicity. Studies have shown that PFASs can cause adverse effects on the metabolism as well as the endocrine- and reproduction systems in organisms. In this study, PFASs were investigated in glaucous gull (Larus hyperboreus) (n=5) and black guillemot (Cepphus grylle) (n=4) from Svalbard.

Samband mellan en längre tillväxtsäsong och en ökad smoltstorlek i Vänerområdet

AbstractThe purpose of this study was to see if there is a connection between smolt length from Brattfors salmon cultivation and temperature. Climate changes are expected to give a higher temperature that could result in a longer growing season for the fish.Cultivated smolt is today bigger than it was before, it is also bigger than the wild salmon. The growth season of salmonids depend on the water temperature, salmonids need 6-80C to grow. Water temperature has been surveyd since the late 50´s in Brattfors. The result shows that it?s now considerable more days per year with higher temperature.

Mating behaviour and hierarchy among male warthogs (Phacochoerus africanus) in Kenya

Warthogs live under natural conditions in matriarchal groups, bachelor groups and yearling groups. Just like all pig species do warthogs have a complex behaviour repertoire. The semi-wild warthog population at Kichwa Tembo Lodge, outside Masai Mara National Reserve, lives in a fenced area with access to food all over the year and is protected from predators. The aim of this study was to observe the male warthogs? mating behaviour and their hierarchy during the mating season.

?Biblioteken kan inte hålla på att rensa ut? en diskursanalys av Tintindebatten

Should libraries first and foremost be a source of free informationwhere the citizens can find whatever information they want, or dothe librarians have a responsibility for what kind of works theypresent to people on their shelves? A wild debate broke out inSwedish media in September 2012, after the artistic leader ofKulturhuset in Stockholm; Behrang Miri decided to weed out allthe Tintin albums from the children´s library Tiotretton. Hewanted to start a debate on stereotypes in children´s fiction, andwhat damage they do to children who face them. The purpose ofthe thesis is to carry out a discourse analysis of this media debate,and to identify the different views that are expressed on thedemocratic mission of the libraries, what media they shouldpresent. The method and theory is based on the discourse theory ofErnesto Laclau and Chantal Mouffe and their concepts are used toarrange the analysis around certain themes that build up twodifferent discourses; ?Freedom of information discourse? and the?Weeding out discourse?.The two main questions are: What views of the public librariesselection of works are expressed in the Tintin debate in Tiotretton,and how do the views relate to each other? What concepts arespecific for the debate, and what meanings do they get in thesedifferent views?In the concluding chapter I discuss which consequences theseopposing opinions can have for the future selection processes ofthe library..

Investigation of Syndecan-1 Ectodomain Isolated from Chinese Hamster Ovary (CHO) Cell Culture Medium

Syndecan-1 is a cell surface proteoglycan which participates in cell adhesion, differentiation, motility, morphogenesis and intracellular signaling. The two glycosaminoglycans heparan sulfate and chondroitin sulfate are covalently attached to the ectodomain of syndecan-1 via a tetra saccharide linkage sequence. However, the ectodomain can be modified having only one or neither of the glycosaminglycans attached. The glycosaminoglycans are capable of binding ligands such as fibroblast growth factors (FGFs) and support activation of receptors. The ectodomain is proteolytically cleaved from the cell surface by metalloproteinases in a process known as shedding.

Apologia i offentligheten : En studie av Ola Lindholms retoriska försvar mot Expressens kokainanklagelser

On the 12:th of April 2011, the Swedish tabloid magazine Expressen publishes a story, claiming that Ola Lindholm, presenter of critically acclaimed TV-show ?Wild Kids? has been suspected and apprehended on cocaine allegations. The serious allegation called for Ola Lindholm to defend himself against the allegations. His only public response was a blog-post where he claimed his innocence, albeit with some reservations.  The purpose of this paper is to analyze Lindholm?s rhetorical defense.

Förutsättningar för återintroduktion av stora gräsätare i Sverige

Biodiversity is under threat in Sweden and many species are on the brink of extinction. This is mainly due to the large-scale drainage projects during the 19th and 20th century and the increasingly intensive land use in agriculture and forestry. The intensive land use with sharply defined boundaries between the production units has in many cases led to either overgrazing or overgrowing. As a result many species have been pushed back to "leftover" habitats like shooting ranges, power line corridors, roadsides, dumps, embankments and other similar areas. Therefore the question has been raised, wether or not it is needed to re-introduce large herbivores into the wild in order to maintain the biodiversity that is related to the extensive land use.This study has been conducted as a literature review and will focus on the European bison?s (Bison bonasus) impact on other species and biodiversity; conditions for reintroducing large herbivores in Sweden are also discussed.Free roaming populations of large herbivores have a positive impact on plants, insects and many other groups of organisms.

Gods Gone Wild : En queerteoretisk undersökning av Neil Gaimans American Gods

Detta arbete presenterar en systemisk-funktionell analys av elevtexter skrivna av elever i årskurs nio. Det är totalt 24 elevtexter från ett ersättningsprov inom det nationella provet 2012 som analyseras. Tolv av de undersökta texterna är skrivna av pojkar och tolv är skrivna av flickor. Uppgiften eleverna fått är att skriva en novell utifrån en bild.Syftet med detta arbete är att se eventuella skillnader i sättet att skriva mellan pojkar och flickor samt utreda vilka skillnaderna är. För att kunna se detta har elevtexterna analyserats med systemisk-funktionell textanalys för att se processer, deltagare och omständigheter.

Isbjörnars (Ursus maritimus) interaktioner och hägnutnyttjande på Orsa björnpark

SAMMANFATTNINGIsbjörnen är mycket populär hos djurparksbesökare och en viktig symbol för klimathotet, trots detta finns fortfarande många frågetecken kring hur vi ger isbjörnar i djurparker hög välfärd. I litteraturen har vi länge talat om isbjörnar som solitära djur men trots detta låter vi dem ofta dela hägn med andra isbjörnar på djurparker. Det har observerats positiva effekter av grupphållning av isbjörnar, bland annat sänkt förekomst av stereotypa beteenden, men vi måste vidare utreda vilken påverkan det har på deras välfärd. Ytterligare problem för isbjörnar på djurparker är stereotypt vankande som har observerats hos flertalet karnivorer som i det vilda rör sig över stora områden eller hemytor. Syftet med denna studie var att titta på hur isbjörnarna på Orsa björnpark utnyttjar sitt hägn, vilka beteenden som kan observeras samt hur stor del av observationerna de spenderar tillsammans.

Dödsrikets livshistorier : Benkemiska isotopanalyser på artikulerade och disartikulerade individer i Frälsegårdens gånggrift

The aim in this thesis is to use carbon, nitrogen and sulfur isotope analysis on teeth and bone to track diet and mobility of the population as well as the individual level from the articulated and disarticulated individuals from the passage grave Frälsegården, situated in Gökhem parish in the region of Falbygden, western Sweden.50 human samples were analyzed from tooth, mandibula and femur, together with 11 faunal samples from different bone elements of local wild and domestic animals.The results fall well in line with earlier stable isotope work done on passage grave individuals from Falbygden in stable isotopes: A homogenous group with a diet which was clearly terrestrial and lived on a pretty high trophic level. It also seems that the analyzed individuals deliberately focused their food intake to the cultural and natural, megalith and limestone landscape of Falbygden, and not to its surroundings, even if the passage grave is situated in the outermost areas of the region.A small study compares the sulfur results to with earlier work done on strontium isotopes. The results show that the different methods might provide a deeper understanding in the interpretation of the methods, and therefore suggesting that further work should be done to compare the methods..

Selånger deltapark : Sundsvalls nya stadspark - en vision

The river Selångersån runs through thenorthern Swedish city of Sundsvall, splittingthe city in two as it winds through thevalley between Södra- and Norra Stadsbergetand out into the Baltic Sea.The river is a national interest of nature conservationbut at the same time in the middleof an urban development string for the city,creating a complex situation of developmentcontra conservation of natural environment.This project attempts to create a strategy oflandscape urbanism for the area surroundingSelånger Bay, four kilometers upstreamalong Selångersån. A sensitive wetland, todayrather forgotten but with great potentialfor introducing wild nature as an active partof the city. Or rather, initiating a processwhere the built environment can infiltrateand enrich the natural environment gradually.A city park in this location to initiate thisprocess could be a joint project of the city?sresidents with the scope to become a projectin constant development.The idea of the project is to offer a large ecologicalpark and meeting place near the citycenter. This will be achieved by clarifyingthe activities and values that already existin the park, such as the largest living deltai the region, football fields and a medievalchurch ruin, and by creating new paths.
