Use of oxytocin to improve diagnosis of subclinical mastitis caused by Staphylococcus aureus
Mastitis, inflammation in the udder tissue, caused by S. aureus is a big problem in dairy cattle production. It causes suffering for the cow and curing or replacing the infected cow is costly for the farmer. It is known that beef cattle also suffer from mastitis caused by S. aureus.
Investering i spannmålstorkning och lagring på gårdsnivå : en jämförelse av ett silotorksystem med omrörare och en konventionell anläggning
The current situation for Swedish grain farmers facing a situation with decreasing profitability makes it necessary for the farmers to find ways of increasing the margins in their grain growing. Decreasing profitabilities along with Lantmännens closing of grain elevators contribute to the necessity for farmers to invest in grain storing and drying at the farm. By investing in capacity for drying and storage of grain on the farm it is possible to recieve a higher price on the grain sold due to the possibility to sell when the price is higher compared to the harvesting season.
An investment in grain drying and storage with a relatively low investment cost that recently has appeared on the Swedish market is the grain stir drying system. This study contains a comparison of an investment in a grain stir drying system where the grain is dried and stored in the same silo and a conventional drying and storage system.
CFD simulering av kallras : Undersökning av temperatur- och luftbeteende intill höga glasfasader och i vistelsezon med golvvärme som en värmekälla
Glass has sophisticated front properties and are used as facades in high buildings. During cold periods, these glass facades could cause thermal discomfort, due to cold downdraught. Cold downdraught can be countered by placing heaters under glass surfaces. Nowadays technology offers highly insulating windows, which is why there is an interest to investigate the indoor climate with only underfloor heating. The research in this area is limited, and few empirical methods are available.
Framtagning av en förebyggande åtgärd mot kriminalitet vid lastbilstransporter
Boberg at Scania CV AB. The purpose was to investigate the technical and customer oriented possibilities for the development of a transport security measure against cargo crime, which is a growing problem in Europe. The main goal was to develop a concept that is possible to implement in the Scania CV AB Fleet Management System. Another goal was to develop a security model that will be used as a tool during Scania CV AB?s future development projects of transport security concepts.The work was divided into three main parts: a background study, handling cargo crime, transport security Scania CV AB trucks and market analysis, a stakeholder investigation including a questionnaire and interviews, and a concept development session.
Högtempererat borrhålslager för fjärrvärme
The district heating load is seasonally dependent, with a low load during periods of high ambient temperature. Thermal energy storage (TES) has the potential to shift heating loads from winter to summer, thus reducing cost and environmental impact of District Heat production. In this study, a concept of high temperature borehole thermal energy storage (HT-BTES) together with a pellet heating plant for temperature boost, is presented and evaluated by its technical limitations, its ability to supply heat, its function within the district heating system, as well as its environmental impact and economic viability in Gothenburg, Sweden, a city with access to high quantities of waste heat.The concept has proven potentially environmentally friendly and potentially profitable if its design is balanced to achieve a good enough supply temperature from the HT-BTES. The size of the heat storage, the distance between boreholes and low borehole thermal resistance are key parameters to achieve high temperature. Profitability increases if a location with lower temperature demand, as well as risk of future shortage of supply, can be met.
Barriers to convert to organic farming and the role of risk : an empirical application on Swedish data
To understand the motives, and perhaps more importantly the barriers, for farmers to convert from conventional to organic farming is of great interest for policy makers as well as for academics. In Sweden and in other EU countries, proposed targets of the area in organic farmland have failed to be reached in spite of different kinds of policy measures. Most studies agree that the average profitability seems to be comparable to or better in organic than in conventional farming. This would indicate that there must be other factors of importance which can explain the low particiapation rate. A higher perceived risk in organic farming with respect to yield and price is frequently brought up as a potential explanation within a qualitative framework.
Grön marknadsföring i outdoorbranschen : En komparativ flerfallsstudie
Syfte: Syftet med studien är att undersöka hur och varför företag i friluftsbranschen arbetar med grön marknadsföring samt vilken grön strategi företagen har.Metod: Studien är kvalitativ i form av en komparativ flerfallsstudie med en deduktiv ansats. Teorin beskrivs först för att sedan jämföra teorin med det empiriska materialet. Empirisk data har samlats in genom sex semistrukturerade intervjuer och sekundärdata såsom internetkällor och elektroniska rapporter.Teoretisk referensram: Den teoretiska referensramen berör olika områden inom grön marknadsföring. Teorin tar upp segmentering och targeting utefter kunders gröna karaktärsdrag, grön positionering, de fyra gröna P:na i marknadsmixen samt anledningar till varför företag arbetar med grön marknadsföring internt och externt.Slutsatser: Fallföretagen segmenterar inte marknaden efter kundernas gröna karaktärsdrag. Det ligger dock i deras affärsidé eller vision att positionera sig grönt.
TV-marknaden för sändningsrättigheter kopplade till sportevenemang : En spelteoretisk analys
Background: Sporting events conveyed by the TV medium affect people and can give many unforgettable experiences. Sport may be synonymous with excitement and drama or just serve as entertainment. Through TV broadcasts from different sporting events, millions of televiewers all over the world have enjoyed athletic feats of extreme top class. TV broadcast sport always attracts a great number of viewers, also in Sweden. The prices of broadcasting rights to sporting events have risen strongly during the last decade, much as a consequence of the increasing competition between different TV companies both internationally and in Sweden.
Optimering av blandning och lagerhållning av avfallsbränsle : Optimering av avfallsbränsleblandning och lagerhållning av importerat avfallsbränsle vid Vattenfalls fjärrvärmeverk i Uppsala
Fjärrvärmebranschen i Sverige har sedan mitten av 1990-talet varit i en stagnationsfas, där mängden producerad och förbrukad energi i stort sett varit konstant, trots stora investeringar i fjärrvärmenätet. Samtidigt har den höga andelen återvinning gjort att det råder brist på avfallsbränsle till energiåtervinning i Sverige. I kombination med hög konkurrens om avfallsbränslet har detta medfört att aktörerna på marknaden tvingats se sig om efter nya vägar att tillfredsställa behovet av bränsle, vilket lett till att det idag importeras stora mängder avfall för energiåtervinning från utlandet. Vid Vattenfalls fjärrvärmeverk i Uppsala har det mellan åren 2006-2013 återvunnits i snitt drygt 360 000 ton avfall per år. En stor del av detta hämtas in från lokala kunder, både kommuner och privata aktörer, men man har på senare tid även behövt börja importera avfall för att tillfredsställa energibehovet.
Utveckling och tillämpning av en GIS-baserad hydrologisk modell
A distributed hydrological rainfall-runoff model has been developed using a GIS integrated with a dynamic programming module (PCRaster). The model has been developed within the framework of the EU-project TWINBAS at IVL Swedish Environmental Research Institute, and is intended for use in WATSHMAN ? a tool for watershed management developed at IVL. The model simulates runoff from a catchment based on daily mean values of temperature and precipitation. The GIS input data consist of maps with soil type, land-use, lakes, rivers and a digital elevation model.
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.
Näringsretention i återskapad våtmark på betesmark : studier av en mad vid Bornsjön
It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).
Effekter av kön, ålder och region på sjukpenningen i Sverige - en variansanalys
According to TCO (The Swedish Confederation for Professional Employees) the worst threat to the Swedish welfare is that so many people because of bad health and unemployment are not a part of the labour force. If Sweden could make the number of people with health and unemployment problems half the size as today, the GDP would increase with more than five percent. In real money this means 110 billion Swedish kronor a year. According to SCB (Statistics Sweden) the difference between women?s and men?s absence owing to illness should be investigated more closely in order to get at better understanding of the problem.
Gestaltningsfloran : en brygga mellan hortikultur och biotopgestaltning
Contemporary plant design can be examined by how it relates to two extremes - Nature and Art. This idea is explained by Noel Kingsbury in the book The Dynamic Landscape where he places designers and their projects on a gradient (Kingsbury, 2004). Nature, one of the extremes can be represented by a dynamic, species-rich plant design with native species and with nature as the ideal. The other extreme - Art implies a more static view on plant design. Here, the designs
consist of colourful flowers, exotic species and cultivars with double flowers.
Enabling behaviour change : community-based social marketing strategy in Malmö
Our planet is faced with enormous challenges as the extreme weather events related to the human-caused climate change continue to gain strength. The scale of the problem has made changing human behaviour the central focus of sustainable development, and both public and private sector are expected to gain relevant expertise and introduce this work in their agenda.
Over its 40-year history, social marketing has become an established field providing tools for social change, but compared to health promotion, sustainability has not been a major focus of social marketing research so far. At the same time, sustainable lifestyles are embedded in complex systems where both individual factors and those of physical and social environment play a defining role in their adoption. Communities are a good example of such environments, and they became the key focus of Community-Based Social Marketing, which combines different insights from psychology to suggest a step-by-step framework for crafting behaviour change campaigns. However, it has not been applied to larger and diverse communities, like cities, and has not focused on sustaining new behaviour over time, which is crucial for creating sustainable lifestyles.
