Huggormsbett hos hund i Sverige : en klinisk studie och litteraturöversikt

Every year many dogs in Sweden are bitten by the adder, a venomous snake (Vipera berus). Despite the fact that adder bites are so common in dogs there have been few investigations made that study the effects of treatment with glucocorticoids, a drug that is commonly used. We have carried out a literature study concerning adder bites in dogs and a prospective study where case history, clinical signs and treatment have been recorded in dogs that were presented at two veterinary hospitals after a confirmed or suspected adder bite. Fifty three dogs were included in the study out of which 22 were treated with glucocorticoids. In our study, the group of dogs treated with glucocorticoids was compared with the group of dogs that did not receive glucocorticoid treatment by the owner or on arrival at the clinic.

Are changes in heart rate and/or arborisation of vaginal mucus useful parameters for detecting heat in heifers? :

The milk production per cow has increased considerably during the last 50 years and due to the breeding for higher milk production also brings decreased reproduction efficiency. In a Swedish study 1996 it was shown that on average only half of all estruses were detected. Every time a farmer fails to detect oestrus it costs the farmer about 1200 Swedish crones and the need of means of detecting oestrus is therofore large. With this study we wanted to investigate if heart rate respectively crystallisation of vaginal mucus (arborisation) could be useful means of detecting oestrus. We monitored two oestrus cycles in four heifers.

Design av PID-regulator baserad på kommersiell processormodul

The idea to develop  a platform for a PID-controller came from the need to control the temperature in  an espresso machine in a more exact way than a thermostat could perform. In discussions with Syntronic AB the idea developed into PID-control for industrial use. Syntronic AB suggested that the platform should be based on a commercially available processor module to shorten the development time. The suggestion included the use of the microcomputer Raspberry Pi, which supports USB, HDMI, memory card and Ethernet.The work began with establishing a schedule for the 10 weeks of the projects duration, and after that a system specification listing all functions, implementation and limitations was made. When the foundation of the system specification was done, a preliminary system design took shape.Because of the Raspberry Pi´s lack of Analog-to-Digital converter, a circuit board containing Wheatstone bridges, differential amplifiers and a two channel Analog-to-Digital converter was fabricated.

Bostadsområdet Gulsparven, Trollhättan. Förslag till hållbar förnyelse av bostadsområde

Rapportens syfte är att arbeta fram förslag till en hållbar förnyelse av bostadsområdet Gulsparven i Trollhättan, på uppdrag av AB Eidar Trollhättans bostadsbolag. I dagsläget har området energirelaterade problem och är i behov av upprustning. För att komma fram till goda lösningar har litteratur- ochinformationsstudier, intervjuer med erfarna personer samt inventeringar av området gjorts. Förslagen åskådliggörs i form av ritningar samt 3D-vyer.Fyra förslag till förnyelse har tagits fram med olika grad av åtgärder, där två av dem kräver en omprövad detaljplan. Generella åtgärder, vilket gäller i samtliga förslag, är betydelsefulla lösningar för att växa mot rollen som ett hållbart bostadsområde.

Segmentering av lokala nätverk - För mikro- och småorganisationer

Syftet med den här rapporten är att beskriva ett antal olika tillvägagångssätt man kan använda sig av då man har behov av att dela in ett lokalt nätverk i olika segment och med det även kunna reglera trafikflödet mellan segmenten. De lösningar som presenteras i arbetet är inriktade mot mikro- och småföretag.Anledningen till att vi har valt att arbeta med det här området är att vi anser att det är viktigt för organisationer att har en strukturerad och segmenterad design på sitt interna datornätverk.Vi har arbetat genom att i förväg samla in information om olika tekniker som kan tänkas lösa vårt problem, och därefter testat olika scenarion med dessa tekniker. Data har samlats in efter varje genomfört scenario och sammanställts i statistisk form för att kunna avgöra vilken metod som var att föredra.Vi har testat lösningar där man segmenterar nätverket i en lager 2-switch medan man möjliggör och förhindrar trafikflöde mellan segmenten i en router. Även lösningar där man använder en lager 3-switch har testats. På så sätt kan routningen ske direkt i switchen och det blir betydligt mindre belastning i routern.

Världens ämne : Exkursioner i geografiundervisningen

This thesis is a case study of the search function on the University of Uppsala?s web site. The search function in this study was chosen since it exists on a large and complex web site and there were apparent lacks in the old version of the search function. The thesis highlights some of the problems that can appear in the development of a search function on a local site. One interesting find is that one of the most difficult issues is organizational and not technical.

Local poultry production in rural Zambia and the effect of light on poultry performance

Zambia is a country in Southern Africa where poverty is widespread and the traditional keeping of local poultry therefore plays a crucial role in improving nutrition. Meat and eggs from poultry are important sources of protein but also of income. Improving the poultry production is thereby a method to fight poverty. For poultry, the access to light is an important factor for both growth and egg production. In this paper, the focus is on the traditional village chickens used for both egg and meat production, how they are kept, their health and welfare and if the use of a solar lamp will influence their behaviour, growth and egg production. Three studies were conducted in Chibombo and Choma Districts in Zambia were 17 farmers were interviewed regarding the village chicken management of which six farmers participated in a solar lamp experiment.

En kostnadsanalys av energieffektiva flerbostadshus

In Sweden the real estate sector accounts for 33 % of energy consumption and just below 10 % of the emission of carbon dioxide. As a consequence of the external pressure from climate change it?s in everybody?s interest to reduce the energy consumption and thus reduce the emission of carbon dioxide. An additional incentive to reduce the energy consumption is the substantial increase of the energy price since the deregulation of the electricity market in 1996.In this study the techniques that exist to build multi-storey residential buildings with high energy performance will be investigated. Further the study intends to investigate the optimal energy performance from a real estate economic perspective.In order to investigate the optimal energy performance a model has been created with the parameters investment cost, rental revenues, operation and maintenance cost, discount rate and investment horizon.The result shows a relationship between a high investment cost and a high energy performance for newly constructed multi-storey residential buildings.

Att leva med barn som har ADHD. : Familjemedlmmars upplevelser av att leva med barn som har diagnosen ADHD.

Syfte: Studiens syfte var att undersöka samband mellan hur universitetsstudenter skattar sin fysiska aktivitetsnivå och hur de registrerar aktivitetsnivå med hjälp av dagbok samt att se om de kom upp i ACSM (American College of Sport Medicine) och WHO´s (World Health Organisation) rekommendationer.Metod: Studien hade en icke experimentell, deskriptiv och korrelerande design där 26 försökspersoner, två män och 24 kvinnor, rekryterades via anslag. De fick först svara på en enkät och därefter registrera sin aktivitet via en 7-dagars aktivitetsdagbok.Resultat: Studenterna ansåg inte att de hade en stillasittande livsstil och alla deltagare utom en ansåg sig komma upp till ACSM´s rekommendationer av fysisk aktivitet 30 minuter per dag av måttlig intensitet alla dagar i veckan. Trettiofem procent kom inte upp i WHO´s rekommendationer och av dessa överskattade 67% sin fysiska aktivitetsnivå. Sextiofem procent kom inte upp i ACSM´s rekommendationer och av dessa överskattade 94% sin aktivitetsnivå.Konklusion: Studenterna hade en låg fysisk aktivitetsnivå utifrån ACSM´s rekommendationer och majoriteten av de som inte levde upp till WHO och ACSM rekommendationer överskattade sin fysiska aktivitetsnivå. Det krävs dock mer omfattande studier för att dra några generella slutsatser då denna studie hade en skev könsfördelning och ett lågt antal deltagare.Keywords: Self-estimation, Perception, Activity diary, Physical Activity level, Overestimation. .

Effekter av nya PBL : En studie av processen från handläggning av bygglovsansökan till slutbesked

It has now passed two years since the new site- and construction law, PBL, went into force. It replaced the previous PBL applicable since 1987, and it involves relatively large changes in many different areas of the construction sector. The ambitions of the new law are for instance to simplify and clarify the legal text, increase efficiency in the permitting processes and improve the quality of construction. To achieve this, a variety of changes was made. Some of the most important are: inserted deadline in the processing of building applications, extended assessment of building applications, revised rules about controlplan and quality manager, a certificate is required to start and end the project, an additional meeting is inserted and the construction management of the municipalities will have to do a mandatory visit at the work scene.

Ex - dagseffekt : En studie kring avkastning på ex - dagen för utdelning

Question:"Does the market possess perfect information as the efficient market hypothesis says?""Is there any significant relationship between the abnormal stock return on the ex ? day and the dividend?" Purpose: The purpose of this study is to enlighten and find understanding about stock return versus dividend on the ex ? day and try to figure out if abnormal returns occur on the portfolio during dividends.Methodology:The study was based in a quantitative nature and was derived with an event study and a hypothesis testing. The authors investigated the thirty most traded shares on the Stockholm stock exchange during a period of five years (2005 ? 2009). They were analyzed during a total of nine days; the estimation window was set to sixty days.

Identifiering av konfliktbestånd med hjälp av laserskanning

The interest in harvesting wood fuel in conflict stands has grown in recent years as a consequence of the increased demand for biofuel. Conflict stands are young forests that have not been cleaned and have a large number of stems ha-1with a great height and diameter distribution. This means that traditional field measurements in conflict stands are difficult and very time consuming. Therefore, the forestry sector is in need of new, more efficient inventory methods. In this study, the Lidar data from Lantmäteriet?s (the Swedish mapping, cadastral and land registration authorities) new national height model was used in combination with plots from the Swedish national forest inventory from 2009 to create functions for; height, volume, diameter and number of stems.

The surface wanted is a surface with both low frictional forces and smallleakage. This study was done with the goals of investigating and determining existingsurfaces due to the frictional force and leakage. How can we in an easy mannerdescribe these?A number of ten front forks were part of a main study.

Schiele & Klimt - konstnärer av sin tid?

Through participant observation in a local promoter group of hardcore punk shows inGothenburg and qualitative interviews with its members I have investigated links between taste in music, values and social structures in the hardcore punk scene. The theoretical framework of this essay is built upon the concept of subcultural capital, which is adapted from Pierre Bourdieu and developed by Sarah Thornton and Keith Kahn-Harris. The result shows how members among the hardcore punk scene create and preserve distinction towards others, while the distinction becomes important benchmarks for including and excluding practices in the scene..
