Etik och moral inom ridsporten : med fokus på fälttävlan

Eventing is often called as the formula 1 in equestrian sports and comprises three disciplines: dressage, show jumping and cross-country. The sport provides excitement, challenge and joy and is the ultimate sport for intelligent riders and horses. Many are fascinated by the challenges the sport offers while other consider it foolhardy to ride a cross-country. Eventing is not a risk-free sport and has even been given the label of being one of the world´s most dangerous sports. What do those risks mean to the horse? And particularly, is it associated with good animal ethics to use the horse for eventing? Finding answers to these questions is not easy as it probably is not a clear and simple answer.

Slaktsvins basala behov i kommersiell uppfödning : Slaktsvins basala behov i kommersiell uppfödning oönskade beteenden, skador och välfärdspåverkan

The Swedish Welfare Act § 4 says that "Animals must be kept and cared for in a good environment for animals and in such a way that promotes their health and allow them to behave naturally." Pigs in the wild spend 80% of their waking hours walking around and rooting for food, eating and exploring their environment with its snout. Fattening pigs in commercial farms spend 80% lying doing nothing. A lactating sow is lying down most of her day, and only 10-20% of the body surface is in contact with the floor, so the pressure is high on these spots. Piglets lie down and paddle with their legs, with high liquid content in the tissues, several times an hour, to stimulate and massage the sow's udder. In the existing system, these individuals are held more often on floors that are anything but inviting to sleep on.

Translokation av större vattensalamander : -bevarandestrategi eller riskåtgärd?

This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.

Fosforavskiljning och hydraulisk konduktivitet i markbaserade reningssystem ? Kornstorleksfördelningens betydelse

Fosforutsläpp kan leda till övergödning i vattenrecipienten om kritiska nivåer överskrids. De enskilda avloppen står idag för en relativt stor andel av Sveriges fosforutsläpp jämfört med de kommunala avloppen. Detta kan sättas i bakgrund av att staten, alltsedan 1970-talet, har lagt ner stora resurser på att reducera utsläppen hos kommunala avlopp, medan en motsvarande satsning på de enskilda avloppen uteblivit.Merparten av dagens enskilda avlopp utgörs av markbaserade reningssystem, det vill säga avloppslösningar där avloppsvattnet får passera genom markmaterial för att renas. Fosforreningen i markbaserade reningssystem har forskningshistoriskt sett inte varit en prioriterad fråga, vilket har lett till kunskapsbrist inom området. Naturvårdsverket har i och med miljöbalkens införande skärpt sina krav på fosforreningen hos enskilda avlopp.

Spårning av miljöstörande ämnen i Uppsala stads spillvattennät

To the sewer systems households, industries and other activities are connected. The wastewater is collected at treatment plants where a nutritious sludge is produced. The sludge does not only contain nutrients, but also hazardous substances originating from different activities in society. To reduce the flow of hazardous substances to treatment plants and to create a sustainable recycling of plant nutrients the Swedish Water & Wastewater Association has developed the certificate system REVAQ. This certificate requires a good quality of the sludge but also that the treatment plants maps the origin of the unwanted substances.

Modeller för brösthöjdsålder för tall och gran :

The purpose of this study was to develop two types of prediction models for Scots Pine and Norway Spruce. The first type for calculation of the stump diameter under bark the year the tree reached breast height (Dstubh130). The second type for calculation of the annual difference, e.g. the number of growth years between stump height (0.2 m) and breast height (1.3 meters above ground level). The primary thought with these prediction models is to obtain the breast height age in the trees on basis of the number of annual rings at stump.

Inventering av förorenad mark på LKAB´s industriområden i Kiruna, Svappavaara och Malmberget :

The county administration asked LKAB to make an inventory of possibly contaminated sites caused by their mining activity. The inventory should be performed according to the MIFO model, a method from SEPA which is used to assess a contaminated site. The first phase involves collection of information through interviews and site inspections and in phase 2 a general survey with field sampling is conducted. LKAB started the work with the first phase of the survey during 2003. During this project the information collected in Phase 1 was evaluated and 16 of the sites were chosen to proceed to MIFO Phase 2 (six sites in Kiruna, and 5 sites respectively in Svappavaara and Malmberget). The sampling of these 16 sites was performed during week 27 2004.

Kan risken för spontan contortaföryngring elimineras genom hyggesbränning? :

Sweden has almost 600 000 hectares planted with lodgepole pine, and large areas are soon ready to be clear-felled. The provenances that have been planted are producing high level of permanently closed, so called serotinous, cones. In their natural setting, the Canadian boreal forest, these cones are opened mainly after crown fires when the heat make the resin between the cone scales melt, which releases the seeds. This is viewed as an adaption to the fire regimes that prevail over the natural distribution area of lodgepole pine. Because of the short flame-exposure that occurs in a crown fire, the seeds can survive.

How to build a rein tension meter

A large part of the interactions between horse and rider during horseback riding takes place through the reins and the bit and devices for measuring the tension on the reins, rein tension meters, has fairly recently been developed. To safeguard the welfare of the ridden horse riders need to be aware of the rein tension they apply and actively work to decrease it. Furthermore, there is a need to develop the study of rein tension through new techniques and refined analysis procedures. A good-quality rein tension meter should be small in size, sensitive, durable and as accurate for light rein tension as for strong forces. Rein tension meters used in research on horse and rider interaction commonly depend on strain gauge technique for generating rein tension data.

Analys av designalternativ för snabbare dynamik i kolkraftverk med koldioxidavskiljning

Combustion of fossil fuels is today the dominating source of energy. During combustion,carbon dioxide is formed. The carbon dioxide accumulates in the atmosphere,which raises the global average temperature on earth through the so called greenhouseeffect. The only way to reduce the emissions of carbon dioxide from combustionin a coal fired power plant is through carbon capture and storage (CCS).Post-combustion capture is a technology to separate carbon dioxide from the uegas after the combustion for efficient transport and storage. The steady state operationof coal fired power plants with post combustion capture has already beenthoroughly investigated on a pilot scale, however much work remains to investigatethe plants dynamic operation.

Klimatsäkrare städer : klimatförändringar, stadsplanering och översvämningar

The numbers of natural disasters caused by extreme weather are increasing through out the world. A large majority of the research concerning the climate shows that this is a trend that can be expected to continue. At the same time the urbanisation is increasing more than ever and for the first time in history more than fifty percent of the population lives in a city. How we build these cities will have a crucial importance for our adaption to the new climate. In Sweden, our capacity for an adaption are high because of our economic situation as well as our rather well built society.

Dekorering av dispenser för allmänna hygienutrymmen

SCA, Svenska Cellulosa Aktiebolaget, är verksamt inom produktion av personliga hygienprodukter, mjukpapper, förpackningar, tryckpapper och sågade trävaror. Inom segmentet mjukpapper för storförbrukare levererar SCA hygienlösningar under varumärket Tork i form av bland annat papper, tvål och tillhörande behållare, så kallade dispensrar. Företaget vill nu undersöka möjligheterna att dekorera dispensrar, det vill säga trycka ett motiv i form av en bild, en färg eller ett mönster på produkterna, på ett sätt som differentierar dem från konkurrenternas produkter och samtidigt stärker varumärket. Syftet med detta examensarbete har därför varit att med en systematisk designmetodik genomföra ett designprojekt för att utvärdera möjligheterna att dekorera dispensrar. Målet har varit att rekommendera dekortekniker som är lämpliga att använda och ta fram designförslag på hur en dekor skulle kunna se ut för att överensstämma med uppdragsgivarens budskap.Projektarbetet har systematiskt gått igenom produktutvecklingens olika faser.

Vegetationsbekämpning i dräneringsdiken inom ett järnvägsområde i Västra Götalandsregionen

My purpose with this thesis has been tostudy the intersection between Landscapearchitecture and Land Art. They both relateto the landscape in some way whetherit is to the urban landscape or thenatural landscape.What tangent points are there betweenthese two subjects, and can you learnsomething of the artists approach to thelandscape?Land Art is an art movement that began inthe late 60?s, what links are there to thecurrent landscape?Last summer, I travelled around the U.S.for a month and visited the three classicLand Art projects. Lightning Field in NewMexico, by Walter De Maria, Sun Tunnels inUtah, by Nancy Holt and the Spiral Jetty,also in Utah, by Robert Smithson.The sites where visited from half a day upto 24 hours and was described and analyzedwith text and photographs.To visit these sites has been crucial formy thesis and will affect my future workas a landscape architect. The use of themethod has been a thought of mine for along time, particularly to analyze ordescribe a landscape with images.
