Hur påverkas beteende/känslor och fysiologiska faktorer på människa och häst vid interaktion mellan parterna? :
The aim of these two studies was to investigate the possible physiological, behavioural and emotional changes that appear after human-horse interactions and also to find an explanation to why they occur. One aspect that is discussed is whether the wellbeing of humans can be coupled to interacting with horses and of how the animals respond to the interaction. The first study was performed on 9 horses and their owners, both parts being subjects to registrations during 4 different interaction treatments. The second study was performed on 6 horses with registrations only being performed on the horses during 2 different treatments.
Nine horses underwent 3 different treatments all performed by their owners (H = stroking of the horses forehead, B = brushing and M = stimulation of the withers) in addition to a control round (K). Each treatment lasted for 4 minutes but observations were performed until after 45 minutes from start.
Neonicotinoids and honeybee health : the effect of the neonicotinoid clothianidin, applied as a seed dressing in Brassica napus, on pathogen and parasite prevalence and quantities in free-foraging adult honeybees (Apis mellifera)
Sub-lethal doses of neonicotinoids have been shown to negatively impact the health of honeybees. However, most studies to date have exposed bees only artificially to these pesticides under laboratory conditions. There have been just a few well designed and replicated studies of the
impacts of realistic neonicotinoid exposure on honeybees foraging under field conditions. In order to close this knowledge gap, and to test the influence of the neonicotinoid clothianidin on honeybees, we used a study system of 16 paired, spatially separated (>4 km) spring oilseed rape fields in the south of Sweden. The fields were paired according to land use, the surrounding landscape and
geographical proximity, using GIS.
Cross-sectional study of bovine anaplamosis in South-western Uganda : the impact of wildlife-livestock interface
The tick-borne disease bovine anaplasmosis is primarily caused by Anaplasma marginale. A variety of wild animals act as reservoirs for A. marginale, but the understanding of their role in the epidemiology of A. marginale is yet poor. This cross-sectional study was conducted to
establish if proximity of wildlife affect the prevalence of bovine anaplasmosis in cattle.
Beteenderesponser hos farmuppfödda minkar (Mustela vison) hållna i stora och berikade burar :
The standard housing of farmed mink provides little opportunities for them to behave naturally and abnormal behaviours such as stereotypic behaviour and tail biting may occur. To prevent abnormal behaviours animals in captivity are often provided with different kinds of enrichments. The aim of this study was to investigate what kind of enrichment farmed mink use when they have several kinds to choose from and to observe if abnormal behaviours can be decreased with a larger cage and a more multifaceted environment.
Totally 20 silver blue, 10 months old female mink were kept in traditional cages (80x30x40 cm) for 7 days and in larger cages (195x80x40 cm) with several types of enrichments for 7 days. The enrichments were wire net- and wooden shelves, wire net- and plastic cylinders, water bath, plastic ropes, branches, straw and tennis balls. One-zero scan sampling on behaviour and choice of place were performed during 3 hours and 20 minutes prior to feeding during 7 days per treatment in April 2004.
Prästgårdsträdgårdar : barndomsskildringar från 14 prästgårdsträdgårdar i Växjö stift
Few rectory gardens are today remaining in their former design and the cultural heritage
that they represent are disappearing. Since 1987-88 the parishes are no longer bound
to keep housing for their priests, which means that they, for economical reasons, are
starting to sell their rectories. With this in mind, a group of people, growing up in
rectories in Småland and Öland between the 1930th and 1950th, formed an interest
group to save the memory of their rectory gardens. On the basis of their memories,
they have written a couple of descriptions of the rectories, which describe the gardens
content, design and the life they once lived there. With this compilation of the 14 rectory gardens I want to keep the memory of them and create a ground for future work in this field.
Historically the rectory gardens played an important roll as patterns and examples in the
countryside.
Nostalgiska Ljud
Det finns ljud som är på väg att försvinna i takt med teknologins utveckling.
Dagens ungdomar har aldrig hört ljud från den äldre teknologin, som den äldre
generationen har fått växa upp med såsom skrivmaskinen, modemet m.m. Dessa
produkter gav ifrån sig ett speciellt ljud som numera inte hörs lika mycket
idag. Men vad händer när tekniken utvecklas till den grad att ljud blir en
säkerhetsfråga? Förutom teknikljud finns det ljud från förhistoriska och
nyligen utdöda djur som forskare har lyckats återskapa genom studier av
kvarlevornas anatomi.
Jämförelse av fyra rundbalspressars packningsförmåga som funktion av grödans torrsubstanshalt :
To succeed, and make money at your animal production you need to feed your animals with
high quality fodder. Other condition to succeed is that you keep your production costs at a minimum. To be able to produce baled silage at a low cost it?s very important that the bales have a high density. Density is measured in kg dry matter (DM) per cubic meter.
The purpose with this report was to learn more about making silage in round bales and to how much the bale density varies between different brands of round balers.

Mykotoxiner och deras effekt på hästens hälsa
AbstractMycotoxins are secondary metabolites produced by filamentous fungi. Moulds producing mycotoxins grow on various crops that are used as horse feeds. Since the treatments of mycotoxin poisoned horses are limited it is important to prevent production of mycotoxins in feed. The major mycotoxin producing moulds in horse feeds are Fusarium spp., Penicillium spp. and Aspergillus spp.
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.
Identifiering av fosfatfosfors käll- och flödesfördelning i ett litet jordbruksområde
Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large quantities to an intensification of growth. Phosphate (PO4) is the fraction of phosphorus that can easiest be taken up by plants and thus have the greatest impact on eutrophication. Increased plant growth in lakes and unfavorable conditions for aquatic animals are two examples of negative consequences. A significant portion of the increased nutrient supply to nearby water can be derived to phosphate leaching from agricultural areas, where private sewers and agriculture is two main sources.
Empathy, altruism and the African elephant
The quest to determine if non-human animals have emotional lives similar to man goes a long way back and is yet to result in a clear answer. The aim of this particular literature study is to determine whether or not the African elephant may host feelings of empathy and display altruistic behaviour. In search for an answer to this question, scientists have chosen to first evaluate the cognitive abilities of said species. They have done this through the testing of tool use, mirror self-recognition, memory and the ability to coordinate with another when performing a task etc. It is generally thought, that in order for complex emotion to exist within an individual, cognition, as an awareness of the self and others, must first be present.

This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.
Satsa på leken! : en studie om skolgårdens betydelse för barns lek och utveckling
The intention of this final thesis is to examine how to create a schoolyard that inspires children at the age of 6 ? 12 years to play and give them possibility to develop. To get a lot of knowledge in this subject, I have combined studies of literature with practical studies at Hosjöskolan in Falun. During my practical studies I have done interviews, walks in the area with the children and visited other schoolyards. I have based a design proposal for the schoolyard of Hosjöskolan on these studies.
En jämförelse mellan amplifierad singelmolekylanalys och selektiv agar vid kontroll av hygienisering av avloppsslam
Bringing back the nutrients from the city to the country is becoming increasingly important, as the world?s stores of nutrients get more exhausted. Sewage sludge is an unapplied resource, rich in plant nutrients, which could replace parts of the commercial fertilizers used in Sweden
today. Sewage sludge may contain large amounts of pathogens, such as Campylobacter and Salmonella, why use can cause severe spreading of infections, both to animals and humans. These pathogens have the ability to survive for a long time in soil and water and therefore
some sort of treatment of the sludge is recommended before use.
