Stereotypic pacing is frequently observed in captive carnivores, however the underlying causes of this behaviour remain somewhat unclear. One of these possible causes are unpredictable feeding signals, which may give rise to frustration and subsequent pacing. Animal keepers at Nordens Ark had noticed that their Amur leopards had shown stereotypic pacing in connection to the passing of ATVs (All Terrain Vehicles) used by animal keepers primarly when feeding the animals in the park. The aim of this study was to investigate whether the stereotypic pacing of the two Amur leopards at Nordens Ark were affected by the introduction of a signal associated with feeding. The leopards were trained by classical conditioning to associate the sound of a siren with the delivery of food by an animal keeper.

År 2006 antog Europaparlamentet och rådet direktiv 2006/24/EG. Detta direktiv, ofta refererat till som datalagringsdirektivet, har fått stor uppmärksamhet främst på grund av den integritetskränkning som direktivet anses medföra. Direktivet innebär att all datatrafik vid mobil och fast telefoni samt Internet och Internettelefoni ska lagras i brottsbekämpande syfte. Våren 2011 röstades införandet av direktivet i Sverige ner i riksdagen och därmed blivit lagd på is i ett år, trots att det som medlem i Europeiska Unionen krävs av Sverige att införa detta tvångsmedel. Detta har medfört att Sverige för andra gången, då Sverige första gången inte införde direktivet inom utsatt tid, döms till böter på miljonbelopp av Europeiska Domstolen.Denna kriminologiska studie avser att undersöka hur ett införande av datalagringsdirektivet i Sverige motiverats utifrån behov samt hur den integritetskränkning som direktivet medför har rättfärdigats.

Populationerna av både vildsvin (Sus scrofa) och varg (Canis lupus) ökar i Sverige. Då deras utbredningsområden först nyligen har börjat överlappa finns i det närmaste inga data på vargars predation på vildsvin i Sverige. Då detta är av intresse för den framtida debatten kring hur populationerna bör skötas, är syftet i denna studie att undersöka vargars predation och vildsvins beteende i Europa för att kunna dra paralleller till hur de två populationerna kan tänkas komma interagera i Sverige. Att göra en studie kring ett rovdjurs val av byte är problematiskt eftersom så många variabler kan tänkas påverka, i kombination med mätmetoder som ofta inte är de mest exakta eftersom det handlar om vilda djur. I jämförelser mellan olika studier måste man dessutom väga in skillnader i val av metod och analys, så att komma med definitiva slutsatser i frågan är inte rimligt. Särskilt eftersom älg, som nuvarande är svenska vargars huvudsakliga föda, inte är så vanligt förekommande i Europa och jämförelser istället får utgå ifrån hur vildsvin föredras i förhållande till hjort. Vargars diet skiljer sig vida mellan de studier från Europa som undersökts, även mellan relativt närbelägna områden.

A high amount of dead wood is one of the most important prerequisites for high biodiversity on forest land in Sweden. Dead wood is most abundant in young forests, thinned forests, woodland key habitats and protected forest land. In old-growth forests most of the dead wood consists of logs and snags, whilst in managed forests a huge proportion of dead wood is made up of logging residues like stumps and FWD, fine woody debris (< 10 cm diameter). All these different types of dead wood may serve as substrates for epixylic bryophytes and lichens. However, few studies have been conducted on the relative importance of these different fractions of dead wood for the occurrence of bryophytes and lichens, especially when considering dead wood on thinned forest land.

Magnesium is one of the most important minerals in the body and it participates in many essential processes, such as energy metabolism and protein synthezis. Magnesium deficiency in cattle may occur when they are let out for pasture in the spring, and is associated with tetany, known as grass staggers. A high yielding dairy cow often loses more magnesium daily in the milk than she has available in the body, and magnesium thereby needs to be provided in the feed to prevent the cow from being affected by deficiency symptoms. The uptake of magnesium is mainly located to the rumen and is not regulated by hormones. The surplus is excreted in the urine by the kidneys.

During recent years the use of TMR (total mixed rations) has increased in Swedish lamb production. For many years TMR has been used for cattle and hence the information and knowledge is vast, while the knowledge concerning sheep and TMR is more limited. The aim of this thesis is to present an overview of the scientific knowledge on the subject, and also to compile practical experience from sheep farmers using TMR. The thesis begins with a literature review where different aspects relevant to the usage of TMR are dealt with. It is concluded that there are differences between sheep and cattle that must be taken into account.

This Master Thesis covers the concept of Green Cars. The background to the research area is the high and rapidly growing number of cars, which together with other factors ad to the pollution of the environment. Under the Kyoto agreement the signing members agreed to lower the emissions of green house gases, further on the EU has a 3-pillar strategy on carbon dioxide and cars. Included in the EU strategy is a voluntary commitment from the car industry to reduce carbon dioxide emissions from new cars. The easiest way of lowering the emissions is by using alternative fuels and engines.

Due to excess precipitation that cause runoff, all soils in Sweden naturally leaches nitrogen.High leaching from arable land is an environmental problem when the runoff reacheswaters. In the international agreement, Baltic Sea Action Plan, the aim is to reduce therunoff of nutrients. Sweden has agreed to reduce its load of e.g. nitrogen to the Baltic Sea.One of the proposed measures is an increased use of site-specific N-fertilization, which hasbeen shown to increase nitrogen use efficiency and therefore also reduce the nitrogen runoff.Either yields are increased with the same total amount of nitrogen, or the total quantityof nitrogen is reduced with preserved yield levels, which is profitable for the farmers.The dynamics of nitrogen leaching differs between top dressing applications above orbelow the economical optimum. There is a consensus about a difference in the dynamics,but not about its magnitude.

This thesis constitutes a long term (100 year) ecological landscape management plan for the estate Götebo 1:5. The estate is situated close to Gothenburg and is owned by Skogssällskapet. The planning has been made by dividing the estate into different areas (zones). In each zone one of the goals nature conservation, recreation or economical yield has been prioritized. Nature conservation is one of the main goals for the forest management plan.

The energy sector is facing an impending paradigm shift. Today?s technology enables the end-user to generate their own energy locally at home. Furthermore, recently developed storage technologies make it possible to balance energy demand with stored energy and integrate district heating with the local power grid. This means that in the future heat and electric power will interact and energy flows is converted over energy boundaries.

I den kriminalpolitiska debatten hänvisas det inte sällan till det allmänna rättsmedvetandet. Vadallmänheten anges ha för uppfattning om lag och rätt i allmänhet och straffnivåer i synnerhet, harbl.a. legitimerat ett flertal straffskärpningar de senaste decennierna. Av denna anledning är detrelevant att undersöka vad allmänheten faktiskt har för uppfattning i rättsliga frågor.Med anledning av utfallen i det s.k. Stureby-målet och det s.k.

Oestrus in dairy cattle has changed over the last decades, the duration has decreased and the intensity of oestrus has declined. A possible explanation can be their high and increasing milk production. Heifers ability to show oestrus is probably not affected to the same extent. The aim of this study was to estimate and compare oestrus duration and strength in heifers of the Swedish Red and Holstein breeds. Standing oestrus has been the primary oestrus sign during many years.

The high incidence of cranial cruciate ligament injury in dogs results in both suffering and significant costs due to treatment and care of affected dogs. Today there are several different technics for surgical treatment in dogs with ruptured cranial cruciate ligament. At University Animal Hospital (UDS), SLU, in Uppsala two fundamentally different methods; TPLO (Tibial Plateau Leveling Osteotomy) and external fixation with suture material are practiced. The aim of this study was to estimate if the different surgery technics result in any difference regarding the function of the dog in a long term perspective. Since motion and function are very affected by arthritis, was the purpose also to determine if there are any differences in developing arthritis between dogs surgical treated with external fixation respectively with TPLO. Development of arthritis is common after surgery or traumatic injuries in a joint, such as cruciate ligament rupture. Unfortunately was the number of dogs in the study to small to achieve two comparable groups.

The purpose of this thesis is to carry out a qualitative study of the perceptions of language teachers as to their role in the teaching of values and morals to pupils. Five language teachers have been interviewed about their perceptions of how values are taught and their role therein. The interviews serve to investigate the reality of teaching values to pupils in a Swedish secondary school and the work involved in this on-going process, this being with a view to having a better understanding of just how important a role the teaching of values plays in the daily working life of a teacher. Terms such as fundamental values and morals can be difficult to define as they are highly personal and can differ from person to person depending on one?s background, experiences and family circumstances, for example.

We have made a qualitative study where we have chosen to interview a number of respondents consisting of ophthalmologists, eye nurses and patients. The purpose of the study was to examine employees' perceptions of patient-related status and treatment and quality, and meaningful participation in the work. The conducted interviews, we then sat in relation to how patients experienced the visit to the eye clinic and their perception of accessibility and hospitality. The result is then compared against the policy of the Title use of internally and we have also tried to explain what is happening with the help of various theorists. Theorist that we made use of is Maslow, Foucault, Deming (TQM) and Herzberg.
