Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.

Wildlife fences are today commonly used along highways to reduce the risk of vehicle collisions with wildlife. Since traffic and roads have expanded over the years, wildlife behaviour has become more interesting not only for the prevention of vehicle collisions but also to understand how human activities impact their natural habitats. Moose is one of those animals that have increased in interest in such studies. In this study, I tested if the probability to cross wildlife fences of moose would increase with increasing home range sizes, and also at what time of the year they cross. The study area is situated in Nordmaling municipality, located in Northern Sweden in the County of Västerbotten.

Svensk Växtkraft is the owner of the biogas plant in Västerås. The company is planning to increase their treatment capacity at their biogas plant. In connection to this work it is also possible to make some energy saving changes to the biogas plant. The objective of this study was therefore to make an electricity and heat survey of the biogas plant, a detailed study of the heat consumption in the sanitation step and also a comparison of energy consumption with the present sanitation method and an alternative strategy where the waste is treated in 55 °C during 10 hours (the current method is heating to 70 °C during 1 hour). The energy survey was conducted in close collaboration with staff at the biogas plant. The current during normal operation was measured, power was calculated and multiplied by the time of usage to obtain the energy consumed.

A future expansion of wind power in the Nordic power system makes the balancing for the transmission system operator Svenska Kraftnät (SvK) more complicated. Up to the hour of delivery the balance responsible parties? (BRP) makes prognoses and plans, for consumption and production, to help maintain the balance in the electrical grid. How well this is accomplished is affected by the setup of the market design. Therefore SvK has proposed the following possible changes in market design: Increase the imbalance costsIntensify the regulation of imbalancesIncrease the temporal resolution on the different marketsPresent the prices for balancing power in real-timeModify the balancing market to simplify auction of consumption bidsA mapping over the BRPs? processes within planning and trading on the day-ahead, intra-day, and the balancing market has been performed in this thesis.

In the dog breed Nova Scotia Duck Tolling Retriever (NSDTR) several dogs suffer from joint pain and possibly pain from the muscles. This diffuse disease is called Immune-mediated Non- Erosive Arthritis in Nova Scotia Duck Tolling Retriever. The disease is most likely of autoimmune nature where the etiology still is unknown. The musculoskeletal symptoms of stiffness and shifting lameness are intermittently seen. Some dogs also have dermatological changes and some dogs suffer from pain when opening their mouth. The study included 20 diseased and 20 healthy NSDTR. The purpose was to describe immune-mediated arthritis in NSDTR based on symptoms, results of analysis and effect of treatment. Among the diseased dogs 65% had serum positive for antinuclear antibodies by indirect immunofluorescense (IIF) ANA-test.

The main purpose of this study was to investigate the effects of the non steroidal anti-inflammatory drug (NSAID) meloxicam in connection with dehorning of goat kids. Six 2-3,5 weeks old dehorned kids were given daily intramuscular injections of meloxicam (0,5 mg/kg; MG) and five age-matched dehorned kids were given isotonic NaCl (NG) for 3 days. The study was randomized and double blinded. The behavior of the kids was studied one day before dehorning, on the dehorning day and three days after. Blood samples were collected each day before the treatment and analyzed for plasma concentrations of meloxicam, hematocrit, cortisol, progesterone and glucose.

The inhuman element in Djuna Barnes?s works has been widely acknowledged. So far the research has, however, concerned itself primarily with animality, thus neglecting the importance of things and thingliness in her texts. In this essay I outline a new way of approaching Barnes were things are taken into account as a vital element in her literary world, using theories on prostheses, fetishes and souvenirs. In Nightwood and four of the short stories, ?A Night Among the Horses?, ?Aller et Retour?, ?Cassation?, and ?The Grande Malade?, I examine clothing, interiors, collections, statues and dolls as objects that in different ways harbour meaning, dream, riddle, memory, history, longing and desire.

Maternal behaviour is crucial for the development of the rat pups? behaviour and stressresponses later in life. There are numerous studies evaluating the effects of the dams?behaviours on the pups, but not many addressing what can be made for wellbeing of the ratdams when breeding. Few studies have addressed the question of how the commonly usedrearing environment effects the dams? behaviour and in the long run how it effect the ratsreared to become our research models.

AbstractRunning an individual bookstore is not an easy task. And then to do it in a profitable way is even harder.In this study you will read about what matters to the profitability in a bookstore. There are several aspects of this but it may be of interest to know what is affecting most of a bookstore's profitability.These three theories were researched by examination of previous research. The theories were then compared to the empirical research of an individual bookstore. Developing the empirical research qualitative and quantitative data collection methods was used.

Usability is a way to study how good a website is which is what our research builds upon. On a mission from Liseberg our purpose is to find out if their website liseberg.se is good from a user?s perspective. Our way of carrying this out where grounded upon a qualitative study through observations and following interviews with a number of participants. By compositing tools of method we have started with the theories descriptions of usability tests and we have also used the theories to be able to reflect around and to understand the results from the tests.

The retrospective part of this study evaluates the susceptibility patterns of bacteria isolated from blood in critically ill foals in Sweden. The most commonly obtained bacteria were Actinobacillus spp. (38 %) and Escherichia coli (27 %). Trimethoprim-sulphonamide (TMS) had good efficacy against most gram negative bacteria with the exception of Klebsiella spp. Among 17 Escherichia coli isolates 94 % were susceptible to trimethoprim-sulphonamide whereas all 24 isolates of Actinobacillus spp.

Title: How to manage stress seen from a leadership perspective Authors: Lina Jonsson, Kristian Olsson, Mattias Olsson, Shabnam Tahajjod Supervisor: Marie Aurell Department: Department of Business Administration, IEM Course: Bachelor thesis in Business Administration, FEC 007 Question of issue: How can we understand stress managing at a workplace seen from a leadership perspective? Method: We have chosen a qualitative method for our thesis with inter-views as qualitative data collection. The interviews had a low grade of standardization. Result: On the basis of our question of issue we have drawn the con-clusion that it is important to create comfort at the workplace, that there are a safety and a feeling of handle the work tasks and that there is a plentiful information flow between managers and employees to manage to handle the workplace stress situa-tion..

SAMMANFATTNINGPia Carlsson & Carina Lindström"- Hoppsan, här fick jag en timme, vad ska jag göra då?"En undersökning om hur förskollärare tar tillvara tiden med och utan barn."- Oops, here I was given an hour, what should I do?"A study of how teachers in pre-school are taking advantage of the time with and without children.Antal sidor: 39Vi har båda varit verksamma inom barnomsorgen sedan cirka tjugo år och i vår profession samt på våra praktikplatser under utbildningen har vi ofta hört andra pedagoger uttrycka en tveksam-het, inför hur tiden ska räcka till. Tid anses vara en bristvara, arbetsuppgifterna något som stän-digt ökar och vi tycker oss ana en viss oro bland förskollärare för att kvaliteten för barnen ska bli lidande. De uttrycker även oro för uppdragets allt mer administrativa inslag, där "kring"-uppgifter, som inte upplevs som relevanta för arbetet med barnen, betraktas som "tidstjuvar". Därför ville vi undersöka hur förskollärare förhåller sig till tid och deras syn på syftet med pla-neringstid och kvalitetsarbete.

Background and aim: The number of refugees and unaccompanied children are increasing in Sweden and these people belong to one of the groups that are at higher risk for developing suicidal behavior. At the same time the lack of research on the subject is mentioned several times by different sources. The aim of this study is therefore to investigate suicidal behavior among young refugees between the ages 13 to 18 years in Sweden, from personnel experiences in social services.Method: We have chosen a qualitative approach with seven narrative interviews that each lasted for about one hour and were recorded. The interview guide was semi structured. The respondents in this study consist of one student counselor, workers from two child psychiatry departments and four different residential care homes for unaccompanied children and young persons.Results and conclusions: The respondents had the understanding that young refugees have been through a lot, lost their families and experienced difficult traumas and a tough refuge.

Volvo Construction Equipment is one of the worlds largest manufacturer of heavymachinery. In Braås, Sweden, they develop and manufacture articulated haulers inseveral sizes. The biggest, the A40, is capable of loading almost 40 metric tonnes.These haulers have a bogie to distribute the forces of the load evenly onto the two axlesand there wheels. The bogie is constructed using a rigid balance beam on each side ofthe frame connecting the axles or an independent solution using hydropneumatics.An analysis has been made in order to establish the forces created during corneringand through the theory, an estimation of the extensive tyre wear and extra fuelconsumption has been made. All due to the effects of the tyres not being inline with thecornering radius.
