Sol, jord och vatten. : Barns tankar om den ekologiska processen
Studies show that the interest and knowledge about science among teenagers is decreasing. They also reveal the difficulties to explain the ecological processes and that the ideas about the nature are collected from everyday life and early school years.The intention of this investigation was to find out more about children?s ideas and knowledge about the ecological processes and to compare these results with the curriculum.The method was a questionnaire and interviews with children in school year 1 ? 6. The aim of the studies was also to find out if any progress connected to age could be found, concerning understanding of the ecological processes.The results showed difficulties in achieving the predestined goals for biology and chemistry concerning ecology cycles and they differed a lot between the children. Often the learning process showed very little progress.
Behandling av sommareksem hos häst med cetirizin : ett fältförsök
In this study we intend to evaluate the effect of cetirizin, orally administrated to horses with insect dermal hypersensitivity. The study comprised 156 horses from 49 farms, which were located in different parts of Sweden. The horses were matched on the farms and were given cetirizin or placebo in a double blind test. Veterinarians collected a blood sample and examined the horses visually, before and after three weeks of treatment and filled in given forms. The results are based on the veterinarians? subjective evaluation of the clinical appearance of the allergic dermatitis before and after treatment.
Galoppträning och körning med två travare
The aim of this study was to evaluate whether gallop training, rather than regular drive training, is worthwhile for trotters race performance. Another aim of the study was to expand the author?s riding- and driving capacity, and get more practical experience on the impact of interval training on trotters. The sample population in the study was two trotters, one Standardbred, and one cold-blood. Given the small sample population, the results of the study is only indicative on the effects of gallop training on trotters, and not conclusive.
Improvements in milking management through imitation of calf behaviour
Approximately 20% of the milk within the udder of a cow is stored in the cistern and immediately available for milk removal, while activation of the milk ejection reflex is required for removing the remaining milk stored in the alveolar compartment. The aim of this literature review is to describe, evaluate and consider implications of the three different suckling activities that the calf displays during a suckling bout. In terms of milking, these phases are represented by pre-stimulation, stimulation during milking and post-stimulation. Pre-stimulation is commonly performed in order to induce the milk ejection reflex, whereby the hormone oxytocin is released and the alveoli in the secretory tissue are contracted. Time requirements regarding pre-stimulation must be considered in relation to lactation stage and milking interval.
Bibliotekarier och biblioteksassistenter. Två yrkesgrupper som krockar?
The purpose of this thesis is to examine the relationship between librarians and library support staff in public libraries regarding status, distribution of work and working climate. We were interested to know if there is a conflict between the two occupational groups and how it can be explained. We also wanted to learn what the future holds for the library in terms of professional categories and tasks according to library staff of today. This study is based on twelve qualitative interviews with four heads of libraries, four librarians and four library assistants. Three theoretical approaches were used in the analysis of the interview material: professionalization strategies, conflict theories and theories from group psychology.
Reklam och nation : Nationsformering i Sverige under andra världskriget
This thesis studies the Swedish advertising business as an actor in the national formation of Sweden. It argues that earlier research has ignored to see advertising businesses as possible forces of these formations. The essay investigates how this appears historically through collaboration with an informational organisation that had risen due to the Second World War and that was a part of the national defence. I can, by investigating a discussion that focused on this informational organisation and the advertising businesses relation to it, show how the business as an effect of a civic engagement expressed an interest to participate in the informational work. The thesis will also, through the pamphlet Om kriget kommer.

?Att visa framsidan är självklart? ? Exponering av medier på folkbiblioteks webbsidor.
Several public libraries are displaying media, such as literature, on the websites of their own. The purpose of this Master?s thesis is to make a survey of the display phenomenon at Swedish public libraries. Therefore the authors of this essay seek to understand why media is being displayed on the websites of public libraries, how it is being displayed and what kind of consequences the displaying will provide according to the respondents. The theoretical framework is based on different theories where marketing and availability defines the equal summary.
Metadon till hund : klinisk farmakologi
Methadone is frequently used as an analgesic drug for dogs although there are very few studies describing the pharmacokinetics of methadone in this species. In man methadone has a long half-life and there are considerable differences in pharmacokinetics between individuals. The dose interval is lengthened when the drug is used fore longer periods of time due to prolonged half-life. Therefore the drug dose must be adjusted individually. The purpose of this study was to study the fundamental pharmacokinetics of methadone in dogs, and to find an optimal drug dosage.
Outbreaks of African swine fever in domestic pigs in Gulu district, Uganda
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.
Brunstvisningsförmåga hos SRB- och Holsteinkvigor
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.
Bland Bokbaciller och Vingklippta Änglar ? En kvalitativ studie kring bestånd och beståndsarbete på fem sjukhusbiblioteks barn- och ungdomsavdelningar
The main purpose of this thesis was to examine the collection management at five different hospital libraries´ children and youth?s section to discern different roles of the collections. We made qualitative interviews with five hospital librarians. The purpose was also to see how the collection development affected the different roles of the collections. We used two theories.
Kan supplementering med omega 3 förbättra syreupptagningsförmågan hos idrottare?
AbstractTitle: Does supplementation with omega 3 improve oxygen uptake among athletes?Author: Jonna Gustafsson and Maria Bohlin Nygren Supervisor: Frode Slinde Examiner: Ingrid Larsson Programme: Programme in dietetics, 180/240 hp Type of paper: Bachelor?s thesis in clinical nutrition, 15 hp Date: May 26, 2015Background: Previous research has shown that omega 3 fatty acids may improve cardiovascular functions by decreased aggregation and increased red blood cell deformability. This produces an increased blood flow and could have a potential effect on oxygen uptake. Optimal aerobic capacity is a determinant factor of performance within endurance exercise.Objective: To compile scientific research of the possibility that omega 3 supplementation could improve oxygen uptake among athletes.Search strategy: The literature research is based on searches in PubMed and Scopus with the terms ?Physical Endurance?, ?Oxygen Consumption?, ?Fatty Acids Omega 3?, ?Dietary Supplements?, ?Exercise?, ?Fatty Acids Essential?, ?Docosahexaenoic Acids?, ?Eicosanoic Acids?, ?Fish Oils?, ?oxygen consumption?, ?maximal oxygen consumption?, ?VO2 max?, ?athlete?, ?omega-3 supplementation?, ?physical endurance?, ??-3?, ?omega-3?, ?Maximal Aerobic Power?, ?Oxygen Uptake?, ?VO2? and ?Maximal Aerobic Capacity?.Selection criteria: Randomized controlled trials (RCT) with an intervention of omega 3-supplementation during three weeks or more were included.
Hur tron finner ankarfäste. Pastorers informationssökande i sin andliga tjänst
This Master?s thesis concerns the information behaviour of pastors in nonconformist churches (especially new evangelical and Baptist church communions) in Sweden in their spiritual service to the local parish. The thesis also looks into how the information flow functions in the pastors? context and why the information need appears as it does. The theory used in this study is contextual analysis based on Buckland?s, Weber?s and Patrick Wilson?s theories on authority and power structures.
Vanliga helminter hos hund, katt och häst i Sverige : artbeskrivning och laboratoriediagnostik
This report includes common helminths, symtoms, routes of infection, diagnostic laboratory techniques and prophylactic methods to prevent infection. We have pointed out where there is a risk of zoonotic transmission and how to avoid contamination and infection. We have restricted the number of species to the most common helminths. Some of these helminths do not naturally occur in Sweden (yet) but are nevertheless of current interest when we travel across borders with our horses, dogs and cats.
The diagnostic part of our report tells about different techniques to find an occurance of helminths in samples of faeces, blood, urine or saliva from a horse, dog or cat. We also write about some recommendations on treating parasitic infections and the development of anthelmintic resistant helminths that originates from incorrect use of anthelmintic drugs
