Animal welfare is impaired if the diet does not provide sufficient feeling of satiety or the ability to perform natural feeding behavior. Pigs are omnivores and spend most of the day searching for food by rooting, grazing and chewing. Both inability to perform foraging behavior and insufficient feeling of satiety often leads to direction of foraging behavior towards stereotyped and abnormal oral behavior. Dry sows are often fed restrictively which leads to unsatisfied feeling of hunger. Dietary fiber has been found to reduce stereotypic and abnormal behavior as well as aggression, which could indicate that pigs need to forage has been met giving a feeling of satiety.

This study focuses on small scale hydropower in Sweden. This means plants with a capacity of up to 10 MW. The study has a special focus on plants with a capacity up to 2 MW. The study has three aims. It strives to describe the small-scale hydroelectric industry in Sweden.

SammanfattningSyftet med den här studien var att utveckla och optimera FISH (Fluorescense In Situ Hybridisation) tekniken som en snabb och ganska billig metod för detektion av laktobaciller. Det vill säga att kunna på objektsglas använda FISH tekniken för att identifiera laktobaciller på artnivå med fluorescensmärkta prober mot 16S och 23S RNA. FISH är en allmän och användbar metod för att detektera och lokalisera mikroorganismer eller en specifik grupp av mikroorganismer i provet (1). Metoden detekterar DNA- eller RNA- sekvenser med hjälp av fluorescensmärkta prober som hybridiseras specifikt med komplementära målsekvenser i intakta celler (2). Detta innebär att man behåller cellmorfologin och tillför en lättdetekterad fluorescerande färg.

The objective of the present study was to evaluate distillers? dried grains with solubles (DDGS) as a protein source to rainbow trout (Oncorhynchus mykiss), by studying digestibility and growth measurements. One control diet, totally lacking DDGS, and three test diets were made containing 10 % (low), 31% (medium) and 51 % (high) DDGS respectively on dry matter (DM) basis. The control diet and the test diets were made to be as nutritionally equal as possible. Wheat bran was used to balance the fiber content of the diets.

Predation is one of many factors that form the structure of the macroinvertebrate community in lakes, wetlands and watercourses. Earlier studies lack an examination concerning how fish- and waterfowl predation affect macroinvertebrates during shorter periods in the spring. I performed an exclosure study in the shallow eutrophic Lake Tåkern which is located in the western part of Östergötland County, Sweden. The experiment was performed during a three week period (1-21 April 2012) when the water temperature was low and the density of migrating diving ducks was high. The experimental cages used included three out of four different treatments; general predation (open cages), bird exclusion (net with mesh size 90*45mm) and no predation (net with mesh size 1*1mm).

Some children develop externalizing and internalizing behavior problems at an early age. Previous research has often treated these children as a homogeneous group, the purpose of this study is to show that this group of children is in fact heterogeneous. Data from theSOFIAstudy was used and preschool pedagogues were informants. The sample contained 2121 boys and girls between 3-5 years. Groups of children with the behavior problems and the risk factors AD/HD symptoms, fearlessness and callous-unemotional traits were created.

Cannibalism can have major influence on fish population dynamics. A prerequisite for cannibalism is that the cannibal and the potential victim meet, and besides density effects, the encounter rate between cannibals and their victims is therefore also largely dependent on habitat use and habitat heterogeneity. In this study I quantified and compared the potential for cannibalism in stream-dwelling European grayling populations in three rivers in Jämtland by means of habitat classifications. I also analyzed population dynamic consequences of varying the potential for cannibalism in terms of intensity, using a physiological structured population model. Findings based on habitat characteristics were that the potential for cannibalism is in general not favourable in these types of streams.

This thesis presents the work of developing and testing a programming tool specially designed for children. The purpose of this tool is to make children capable of creating visual simulations and games that consist of actors interacting in a virtual world. The name of the programming tool is Behavior Cards, which comes from the fact that actors are programmed by giving them cards representing different kinds of behaviors. Behaviors are to some extent pre-programmed and can include general events specifying how the actors should act in different situations, in contrast to specifying every possible situation that can occur. The idea is that Behavior Cards should be easier to use than a more traditional text based programming tool, but it should also be expressive within the domain of visual games.

Many people turn to documentaries for knowledge about animals, but do documentaries give us a truthful portrayal of animals and their behavior? This study looks at how the communication behavior of the portrayed animals is depicted in three episodes of The Life of Mammals. These episodes were observed after which the contents were compared to scientific literature on the same topics. The results show that quite little communication is actually shown in the episodes about plant predators and meat eaters and relatively much of it is shown in the episode named Social Climbers, involving primates. The matching literature suggests that based on the narrative and the accompanying footage, the viewer is getting a realistic picture, with the exception of a few questionable cases..

The society today is full of new changes within the companies and their middle chiefs. Middle chief?s visions have changed during recent years. The female chiefs have grown in numbers, and because of that people have started to focus on whether there are any similarities or differences between the female and male leadership behaviors. The essay is about similarities and differences between female and male middle chief?s idea about effective leadership behavior.Our analysis is based on a qualitative study, where we have made four interviews with four chiefs in industrial companies.

Ammerån which is a small forest river in eastern Jämtland is a well-known river that has been a popular fishing river for a long time. The actual Ammerån begins downstream the lake Solbergsvattnet at Hammerdal and flows into the Indalsälven 10 km upstream Hammarstrand. The river environment switches between forests with wilderness feeling and open agricultural land. The entire Ammerån is today a nature reserve and protected from hydropower development. Fishing in Ammerån has mainly been focused on trout and grayling, and is so even today.

Fish-head pendants are one of the characteristic Gotlandic Late Iron Age artefacts. This object has been rather neglected and mainly considered as an insignificant embellishment, normally worn as a neck-collar and seen as an artefact include in the typical Gotlandic set of female jewellery.The fact that the fish-head pendant has a very long life span, which stretches from grave-finds in the Early Vendel Age to hoards in Viking Age as well as secondary usage as brooches in the Early Middle Ages, makes the artefact an excellent starting point for discussions on social practices and change through material culture. It's shown in this study that, contrary to previous beliefs, the normal usages for fish-head pendants is as solitary pendants and not as neck-collars. Neck-collars is shown to have an intricate relation to inhumations for young individuals, whereas solitary pendants are found in cremation deposits for adult individuals, something that relates to a fixed social practice mainly in the period 700-900 AD and that develops from the cremation funeral practice. This particular social practice relates to aspects of attraction and protection and continues in to the 10th century outside of funeral structures, which is shown by the composition of hoard-finds from the 10th century, but is totally absent when the pendants is given a secondary usage as brooches in the end of the 11th and beginning of the 12th century.

Lymphoma is a group of malignant tumour diseases developing in the secondary lymphatic system. These diseases can develop in all organs as lymphocytes are ubiquitously in the body. In connection to mucus membranes we find mucosa-associated lymphoid tissue, MALT, in which lymphoma can spontaneously but slowly develop, mostly at chronic inflammation or at autoimmune diseases. Today these diseases are incureable with the exception of some cases caused by Helicobacter pylori-infection. Antibiotic treatment of these cases can induce remissions.MALT-lymphomas have characteristic histological and molecular properties.

The purpose of this study is to search and analyze different logics that operators use in the work of helping juvenile delinquents to break their criminal behavior. New institutional theory is used in this study to analyze the results. The study was conducted through qualitative interviews of six professionals in two municipalities which work with juvenile delinquency. There are two questions that we want to address in this study. The first one is what methods the social workers are using in two middle large municipalities to help youth to brake there criminal behavior.
