Betesdrift för mjölkkor :

The Swedish Animal Welfare Act say that all milking cows must have access to pasture in summer time. That was a gift to Astrid Lindgren o her 80th birthday from the Swedish Government. Sweden is a predecessor in animal welfare, but how well do we live up to these big expectations? In this thesis I will examine how well the pasture for milking cows works. I have been interviewing farmers with milking cows and people in the business. I have also been searching information on Internet, and using the library of Alnarp. Cows that are kept on pasture are exposed to different kind of parasites, but on the other hand they run a smaller risk to getting acetonemi, pareses and udder infection. Veterinary Pierre Nordmark means that cows on pasture are more healthy then cows kept inside all summer.

Examensarbete : examenskonsert & skiva : skriftlig reflektion inom självständigt, konstnärligt arbete

This thesis explores how art produced in the former GDR has been looked upon, handled and exhibited after the reunification of Germany in 1990. Swedish Art History has paid little attention to art in the GDR. The debate starting in the 50s between the spokesmen for abstract art and the defenders of figuration restrained for a long period the ability to look upon art from the GDR without prejudices. This led to a rejection of all figurative art in the GDR and sweeping judgmental attitudes, like it´s all ?kitsch?.

Dödlighet hos gepardungar

Geparder minskar i antal och dödligheten hos ungarna är väldigt hög. Syftet med denna litteratursstudie är att ta reda på varför gepardungar dör och vad som är de största orsakerna. Geparder är utsatta för predatorer på två sätt; rovdjur kan stjäla deras byten eller döda geparder. Därför är studien främst inriktad på vilda geparder. Anatomin skiljer sig mellan geparder och andra kattdjur eftersom de är världens snabbaste landlevande däggdjur. De föder många ungar och har en hög reproduktionsförmåga.

Effekter av predationsrisk på sånglärkors (Alauda arvensis) habitatval på åkermark

Along with other European farmland birds, the skylark (Alauda arvensis) has declined rapidly since the 1970?s. Between 1975 and 2003, the Swedish population of skylarks declined with 64 %. In Britain, the decline is often explained by alterations in farming practices in general and the shift from spring-sown to winter-sown cereals in particular. The dense vegetation structure of winter cereals is limiting the number of breeding attempts possible, causing the entire population to decline.

Förslag till skötselplan för Uppsala högar och Tunåsen : ett exempel på medbestämmande planering

This Master thesis is made at the request of the local municipality of Uppsala in Sweden. The purpose of this work is to create a guiding management plan. Recreation, conservation of the cultivated landscape and the historical environment, conservation biology and the aim of the landowners are all considerd. The area is almost 34 hectares and located north of the centre of Uppsala. Landowners are the National Heritage Board, the diocese of Uppsala, the university of Uppsala, the local municipality of Uppsala and one private landowner.

Fjällfågelinventering i Dalarna : Vilka fågelarter finns där och i vilken miljö hittar man dem?

Studiens mål var att undersöka vilka fågelarter som hittas i Dalafjällen, i vilken miljö man hittar dem samt ifall det fanns en separation mellan arter i val av häckningsplats. Undersökningsytan kom att bli Drevfjällens naturreservat och koncentrerade sig kring högsta fjälltoppen Härjehågna. Sedan flera år tillbaka har detta område inventerats av Länsstyrelsen i Dalarna som en del i deras miljöövervakningsarbete. Data ifrån 2011-2013 års inventeringar användes till denna rapport. Fältstudierna bestod av två rutter där två inventeringsmetoder kombinerades: punkttaxering och linjetaxering.

Naturvärdesbedömning av Utanåfladen; En inventering av vårlekande fisk, bottenfauna och vegetation

There are several thousands shallow bays along the Swedish east coast. Most of them are disturbed by different human activities, and undisturbed bays can be considered as quite unique. In the sheltered shallow bays water warms up more rapidly than adjacent water favoring the growth of vegetation, which in turns is beneficial to spring spawning fish species like perch and pike. It is nowadays more common that coastal habitats are inventoried to facilitate future preservation and planning. The aim of this study was to investigate the shallow bay Utanåfladen (59° 53`31.38 N 19°00`44.90 E) in the north Stockholm archipelago and evaluate its habitat value.

Utopia Trek : utopibegreppets resa genom Star Trek

Humanity has always dreamed about a better world. These dreams has manifested themselves in the vision of Utopia - the good place, but also the non-existing place. Up until World War II man still wrote optimistic descriptions of this ideal world, and spread the idea through literature. In the aftermath of the atomic bomb and under the influence of the cold war, these publications seized to surface in literary surroundings. Despite this utopia did not die - it has only changed.

Aktivt system för tidvattenreglering av Lysekilsprojektets vågkraftsteknik

This report investigates a possible solution to the problem with adapting wave powerplants to work in countries with tidal water. The wire connecting the buoy at the surface with the generator at the bottom needs to adjust to the varying water depth. Our solution to this problem is to attach the wire to a jack which is then placed inside the buoy. The jack is then powered by an electric engine. The report discuss what forces the buoy will be exposed to and then the structural integrity of the design is evaluated through simulations.

Frontier Marknader. : En studie om svenska företagsetableringar på afrikanska frontier-marknader

In the early 1990?s more and more companies of the Swedish public sector were exposed to competition, and this started the debate on how such actions might affect the business and even society.The first chapter examines how the public sector and especially health care, is financed and managed. We also explore what it means to be exposed to competition and find that there are many different ways of exposing the public sector to competition. The study examines dental care as an example of a market with both publicly and privately owned companies. The purpose of this paper is to explore how publicly and privately owned health care companies view their relationship with their consumers.

Stölder och förebyggande åtgärder : en studie hos Holmen skogs entreprenörer och egna maskinlag

This master thesis was performed as a mission from Holmen Skog with the purpose to investigate to which extent their own machine teams and engaged contractors were exposed to theft and vandalism, and most common preventive measures used. With the help of collected data the study should lead to proposals of preventive measures that can help the machine teams in their struggle to minimise theft and vandalism. Theft and vandalism are a big problem for Swedish forest contractors. In a scarce economic situation thefts and vandalism rapidly decrease the profit for the contractors. However, the last years have resulted in a positive awareness of thefts, and more and better preventive measures have been developed. With the initiative of this master thesis, Holmen Skog show that they are aware of the situation and that they wish to take control of the problem. A total amount of 108 questionnaires was sent out to Holmen?s own machine teams and engaged contractors.

Movement pattern and habitat use of female grass snake (Natrix natrix) in a semi-urban environment

Rörelsemönster och habitatanvändning hos ormar är ett område där relativt lite forskning har gjorts trots tecken på minskande populationer på flera platser i världen. Snoken (Natrix natrix) är en vanligt förekommande orm i Sverige som tycks vara på nedgång, troligen på grund av en sämre tillgång på äggläggningsplatser. Vanliga äggläggningsplatser i Sverige utgörs av gödselstackar och komposter vilka ger den stabila temperatur som äggen behöver. Dessa har dock blivit både färre och mer svårtillgängliga under det senaste århundradet. Huvudsyftet med denna studie var att undersöka vilka äggläggningsplatser som används i ett område där gödselstackar saknas och hur anpassningsbara snokhonor är till nya områden.

Feromoninnehållande substansers inverkan på hjärtfrekvensen hos tjur :

During the last 50 years the production of milk per cow has increased. This has, however, been followed by a decreased reproductive performance. Shorter and more indistinct signs of oestrus make it harder for the Swedish farmers to discover when the cows are in oestrus. There is a need for ways to control reproduction. The use of pheromones could possibly provide means to satisfy this need.

Axial- och gradientkrympning hos golv på mark enligt Eurokod 2 : Sprickbredders beroende av betongkvalité, tvångseffekter och armeringshalt

AbstractConcrete foundation slabs are usually exposed to unilateral drying during the curing process. The unilateral drying causes an axial shrinkage and a concave curvature of the construction. The curvature results from the fact that the upper part of the slab is drying and shrinking faster than the lower part. This is called gradient shrinkage.A problem occurs when the slab is considered fully restrained by adjoining structural parts. The deformations caused by axial contraction due to the constant part of the shrinkage and the curvature caused by gradient shrinkage of the slab are then prevented by the fact that the slab is fully restrained.

Att vara ung och leva med diagnosen ADHD. En kvalitativ intervjustudie med fokus på sociala och existentiella aspekter

Today many children and youths are allocated to ?The Swedish Authority of Child and Youth Psychiatry (BUP) for the sake of being investigated by means of a neuropsychiatric inquire and many of which are assigned the diagnosis ADHD. During recent years ?The Swedish National Board of Health and Welfare? has declared, in it?s annual account of the current psychiatric state of Swedish Children and Youths, that the healthcare provided for those with neuropsychiatric diagnoses ? such as Asperger syndrome and ADHD, has increased.ADHD is short for Attention deficit hyperactivity disorder, which implies neuropsychiatric impediments i.e. hyper activity, inadvertence and an inability to control impulses.The aim of the Study is to describe and analyze how youth, in the age range of sixteen to eighteen years of age, diagnosed with ADHD define themselves, their daily life, their social state, their next to kin relationships and, finally, their concept of their future.The Study is qualitative.
