The purpose of this paper is to study how the wooded hay meadow of the forest district of northeastern Scania is preserved today, and what local history it has, to thereby achieve a better understanding of the dynamics of the landscape and the complex of problems involved in keeping a historical element of the cultural landscape alive. To accomplish this, literature concerning the subject has been studied, experts have been consulted and an example, the old farm Sporrakulla in Östra Göinge municipality, has been studied. The paper states that the wooded hay meadow constitutes an important part of the history of northeastern Scania, where it provided leaf fodder and hay for the farmers keeping cattle. Today, however, only a few wooded hay meadows remain. One of these is the studied example at Sporrakulla, where juridical protection like Natura 2000 and financial support of maintenance like miljöersättningar make sure that the wooded hay meadow will remain.

Att använda fjärrvärme till lågenergihus kan vara olämpligt pga. höga kulvertförluster jämfört med kulvertförluster för traditionella hus. Detta beror på att det låga värmebehovet i lågenergihusen ger en hög returtemperatur i ledningarna. Ett steg för att öka värmebehovet och göra fjärrvärme mer attraktivt för lågenergihus är att börja värma upp vitvaror (tvätt-, diskmaskin och torktumlare) med fjärrvärme istället för att använda traditionella eluppvärma vitvaror. Vid installation av dessa vitvaror tillkommer en rördragning vars värmeförluster är önskvärda att hålla nere för att dels säkerställa önskad temperatur till vitvarorna men även för att hålla nere internvärmen i huset.I studien har olika rördimensioner och isoleringstjocklek analyserats för att se hur värmeförlusterna beror på strömningsparametrar.

This is a thesis about design of young stands of trees. A big source of inspiration has been Västerskog and Tor Nitzelius Park in Alnarp which both consists of a structure of squares. I wanted to examine if this type of planting could be valuable from an aesthetic and recreational point of view. One problem today is that many people believe that we have to wait for decades for a planting to grow up so that we can enjoy the ?ready result?.

The limit for mercury in fish, set by health authorities, is exceeded in about half of the lakes in Sweden. Methyl mercury (MeHg) is the most toxic form of mercury and accumulates in fish. Therefore transformation of inorganic mercury (Hg) to methylmercury (MeHg) is an important process that we need to understand in order to possibly counteract the negative effects of mercury in the environment. The seasonal dynamics of mercury biogeochemistry is likely of great importance for the accumulation of MeHg in the aquatic food web. In thesis the chemical speciation and transformations of Hg and MeHg in bottom waters and sediments is followed in Ängessjön, a small lake located on the east coast in the middle of Sweden. The lake is not directly affected by any industrial pollution and concentrations of Hg in the sediment reflect the atmospheric deposition in this area, as well as processes taking place along the hydrological pathways from soil to lake. Samples from sediment, bottom- and streamwater were collected in average every second month during the period Feb.

Rågsved ligger i Söderort tillhörande Stockholms kommun och har en population på ca 10 000 invånare där hälften utgörs av utrikes födda och området har en hög segregation. För att kunna skapa ett lugnare och tryggare Rågsved har det öppnats ett litet poliskontor och ett fåtal poliser ska i första hand försöka komma i god kontakt med de som bor i området, främst med ungdomarna som bor och går i skolan i Rågsved. Vidare samverkar de med skola och andra myndigheter i Rågsved för att förbättra den problematiska situationen. Således är syftet med denna studie att undersöka hur ungdomar boendes och studerandes i Rågsved förhåller sig till det nya poliskontoret och vad den ökade polisära närvaron har inneburit för ungdomar som går i Rågsvedsskolan. För att kunna besvara frågeställningen utförs semistrukturerade intervjuer med 11 killar som studerar vid Rågsvedsskolan.

Vi upplever att det i dagens samhälle gärna uttrycks åsikter om vad som anses vara rätt eller fel i olika sammanhang, likaså när det gäller ledarskap, många bär på tankar kring vad som anses vara det perfekta ledarskapet. Ställs frågan får man inte sällan ett detaljerat svar med specifika kvalifikationer. Vi misstänker att åsikter och värderingar som florerar i samhället kan få oanade konsekvenser. Följande kvalitativa studie syftar till att genom en fallstudie på fyra djupintervjuer försöka avslöja olika strategier som tillämpas för att exkludera unga chefer i företag. Genom att blottlägga dessa strategier hoppas vi samtidigt göra dem mindre verkningsfulla.

Examensarbetet utfördes på University of Florida vid Department of Mechanical and AerospaceEngineering i deras Energy and Gas Dynamics Systems Laboratory. Laboratoriet forskar på enny gasturbincykel som producerar kraft, värme, kyla och vatten. Cykeln är kallad High PressureRegenerative Turbine Engine (HPRTE) och kombinerat med gasturbincykeln är ettabsorptionskylsystem (VARS). Kylsystemet drivs av spillvärme från avgaser som cirkuleras igasturbinen, den producerade kylan används för att kyla ned högtryckskompressorinloppet.Syftet med det här examensarbetet är att undersöka möjligheten till att kyla ned inloppet tillkompressorn till temperaturer långt under fryspunkten för vattnet i den fuktiga gasen. Om gasenskall kylas till nivåer under fryspunkten måste vattnet föras bort från gasen.

The main purpose of this study is to inquire whether music can function as a supportive and compensating tool for children from various kinds of social exposure. Eurhythmics is the musical method focused on, since it consciously works out of a socializing perspective. The study involves a scheme with poor children in Argentin (autumn 2005) and is based upon two interviews with women working professionally with both the social and the musical aspect of the current question. Notes from the above mentioned project are added to the interviews. The possible conclusion from the end results is that the individual as well as the dynamics of the group (as a whole) draw positive benefits from not only the music itself but also the structure and the elements of it.

The Psychology Driving and Barriers to Skunk Work Projects (referred to throughout this thesis as the paper) represents a study predominantly on Tetra Pak from a selective perspective, the innovators. Innovators both past&present whose initiatives contribute to the well being of Tetra Pak as well as one from Ericsson were consulted. As with individuals, organizations possess definable characters that are influenced by the various stages of their life cycle. Theories of corporate life cycle phases and organizational character analysis were therefore employed to identify and explain organizational barriers to skunk work leaders&managers. Predicated on the Organizational Character Index survey developed by William Bridges PhD (himself a recognized leader in the field of transition management) and administered to sixty-one managers within a Tetra Pak business unit established the benchmark.

The demand for animal products has increased in the last decades, especially for poultry and pork. Pork production has increased drastically globally, and also in Uganda. Thirty-one percent of Uganda´s population lives in poverty. Pig production is believed to play a crucial role in poverty alleviation, because of the ability to convert low quality feed into high quality protein together with high reproductive potential. African swine fever (ASF) is a lethal disease of domestic pigs often characterized by haemorrhagic fever and with mortality rates up to 100%. The disease is endemic in most sub-Saharan countries and since 2007 in the Russian Federation and Caucasus area.

 AbstractThis Master?s thesis analyses the dynamics of the medieval counterweight lever engine, ortrebuchet, a type of mechanical artillery. The purpose is to study the differences between different types of these machines, and see if computer simulations can be used to validate preserved advice on construction. Simulations include machines with a fixed counterweight, a hinged counterweight and a combination of both counterweights.Due to the almost complete lack of archaeological finds and insufficient historical source material there are still, after more than a century of research, many unanswered questions concerning the design and performance of these machines.The present study is based on an analysis by Jahsman (2004). A more detailed mathematical model employing Coulomb-friction is used.

Linde Material Handling AB i Örebro kundanpassar truckar och har i sitt produktutbud truckar med inbyggd laddare. Detta för att ge kunden en flexibel lösning, som inte är beroende av en specifik laddstation eftersom truckarna då har en anslutningskabel som ansluts till ett vanligt vägguttag. Det finns även en säkerhetsbrytare som kontakten måste placeras i efter laddning, säkerhetsbrytaren är till för att förhindra att trucken körs iväg med kontakten kvar i väggen. Arla är en stor kund till Linde Material Handling, de har haft synpunkter på anslutningskabel och efterfrågat en kabelvinda för förvaring av kabeln. Målet med detta examensarbete är att leverera en fungerande prototyp på förvaringen av kabeln i trucken som uppfyller kundens behov.

BackgroundPeople with psychiatric problems, despite efforts in recent decades still experience vulnerability. Patients with borderline personality disorder (BPD), where self-harm is common, often live in difficult and complex social relationships because of their illness. Additional knowledge and studies about mental illness, self-harm, dialectical behaviour therapy (DBT) and the therapeutic alliance are needed.Purpose and MethodThis study aims to examine how staff perceive and describe: DBT as a treatment method; the therapeutic alliance and the importance it has for treatment. The study utilises a qualitative approach with a qualitative content analysis method and presents earlier research on DBT and the therapeutic alliance. The empirical material consists of focus group interviews comprising three DBT - teams.

Emerging infectious diseases are a recurring threat to both human and animal health. Understanding the multiple causes behind the emergence of new diseases is key to the prevention of new and potentially devastating outbreaks. The list of underlying causes is long, including a variety of anthropogenic, environmental, molecular and climatic changes that promote the emergence and spread of disease. Two of these factors are central to the emergence of new diseases and receive special attention in this study. The spread of disease from wildlife to livestock and diseases that spread from animals to humans (zoonoses) are of importance as they implicated in the majority of EID events.

Chiari type I malformation is a condition in humans characterized by a small posterior cranial fossa, downward herniation of the cerebellar tonsils, foramen magnum overcrowding and disturbances of cerebrospinal fluid dynamics. Syringohydromyelia is often seen in patients with Chiari type I malformation. Syringohydromyelia is characterized by fluid-filled cavities in the spinal cord. This causes damage to the nervous tissue in the spinal cord. In recent years, a condition similar to Chiari type I malformation has been recognized in dogs. It has mostly been seen in Cavalier King Charles spaniels (CKCS). The condition seen in dogs is usually called occipital bone hypoplasia. The aim of the study was to examine whether there is a difference in the shape of the caudal fossa between CKCS, small bred dogs with a similar head shape and dogs with a normal head shape and if occipital bone hypoplasia is related to a head shape with a steep back of the head. Other aims of the study were to examine the crowding of nervous tissue in the foramen magnum in each breed group, the extent of syringohydromyelia and to what extent the malformation had caused neurological signs. Sculls from dogs on autopsy were divided in halves and the position of the cerebellum compared to the level of the foramen magnum was studied.
