Patho-anatomical studies on african swine fever in Uganda
African Swine Fever (ASF) is one of the most serious transboundary swine diseases because of its high lethality for pigs, socioeconomic consequences, rapid and international spread and the absence of either treatment or vaccine. This Sida Minor Field Study (MFS) was carried out during fall 2010, as part of a larger collaborative research project called ASFUganda, focusing on the epidemiology of the disease in Uganda. The aim with this study was to get more knowledge about the pathology in cases of ASF in Uganda, by studying macroscopic and microscopic lesions in pigs with acute and chronic ASF and to detect the ASF virus (ASFV) in tissues by immunohistochemistry.
The pigs were selected from the two different geographical locations in Uganda, Mityana and Gulu district, both with on going confirmed outbreaks of ASF. Necropsies were performed in the field, and the laboratory procedures at the JICA (Japan International Cooperation Agency) Veterinary Pathology Laboratory, Entebbe, Uganda, and at the Department of BVF, SLU, Uppsala, Sweden. Three pigs from an outbreak of ASF in Mityana district showed both the history and the clinical symptoms typical for ASF.
Curatorns ordning : En diskursanalys av curatorns yrkesroll utifrån 15 curatorutbildningar
This study departs from the observation that since the late 1980´s educational programmes for curators have been established and since then expanded greatly. The programmes are part of a process of institutionalization and professionalization of the role of the curator within the international contemporary art field where the role as such has gained much power. Even though many statements have been made about this relatively new phenomenon of curatorial studies, there is a lack of sufficient research. The intention of this study is therefore to examine the educational programmes as such. The selection of 15 programmes has been made with the purpose to include early as well as newly established and to cover a wide geographic area.
Latent värmelagring i vattenburet uppvärmningssystem med elpanna för byggnadsapplikationer
Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.
Upplevelser hos socialsekreterare som arbetar med barn och unga inom myndighetsutövning : - En studie av kritiska incidenter
AbstractWorking with child and youth welfare is one of the most difficult challenges a social worker might face in the field of social work. Those who work with child and youth welfare are more exposed to stress and burnout than other comparable human service occupations. Research links the prevalence of stress and burnout to several key variables, such as demographics, working conditions and personality factors. In contrast, even though social workers in this field face many negative work-related problems they report a high job satisfaction. The aim of this study is to examine how uplifting and straining experiences affect social workers, who work with child and youth welfare, through the use of The Critical Incident Technique and interviews.
Korrektion och imitation som mätverktyg för diagnos av PT-nivå : Kan man korrigera eller imitera en grammatisk struktur som man inte kan producera i fri skriftlig produktion?
The purpose of this study was to examine whether a L2 learner could correct or imitate structures of the language that they could not produce in written production defined by processability theori levels.The Informants had Arabic as their mother tongue. The study showed that the ability of correction developed slower than the capacity for imitation and the ability to written production. The ability of the correction developed by the duration of the stay. The result was a confirmation of theory formation in processability theory. Corrective elicitering could be developed into a useful diagnostic tool in the classroom and thus provide an education that followed a natural learning order according to processability theory by Pienemann.Keywords: processability theori, imitation, correction, written production.
Bioelectromagnetics for improved crop productivity : an introductory review with pilot study of pre-sowing treatment of tomato
Various electromagnetic (EM) treatments has been investigated for their potential in improving crop productivity over the past century. There is today an increasing amount of scientists advocating EM treatments as an organically compatible method for improving plant
growth and yield. However, failure to produce repeatable effects and defining causal mechanisms has made it a study of much controversy and debate. The subject requires indepth
interdisciplinary knowledge, making it inaccessible for the majority of biologists, horticulturists and growers. In this combined literature review and pilot study, these issues are addressed by providing a comprehensive introductory review of the topic plant
bioelectromagnetics and its potential horticultural usability.
Plantinventering och plantkontroll med digitala bilder från helikopter :
This study was carried out as a commission from Holmen Skog, district ?Egen skog? in Norrköping. During October 2006 several stands were inventoried by aerial photos from helicopter. The stands were those for which the next action proposed was plant inventory or plant check. The photos were interpreted and the number of stems was calculated.
Områdets polis eller polisens område? En analys av hur områdespolisen i Bergsjön gör sig relevant för sitt område och sin organisation
The aim of the thesis is to illustrate how a group of community policing officers makes themselves relevant to their community, this in relation to wider organizational circumstances and exterior structures of society. Earlier research on the subject tells us that community policing can be proactive and crime preventing in such a way that the confidence and trust in the police is increased. Research is also making clear that proactive police work is hard to measure and evaluate, which is why my contribution to the field is to explore how this effects the way the police officers in Bergsjön, Gothenburg is making themselves relevant and the way that they see themselves as community policing officers. The relationship police ? community will be regarded as how someone treats their audience, attentive to its feedback, in order to get ones message out, in this case confidence and trust in the police, under influence of the audit society.To achieve the aim of the thesis, participating observation was chosen, to experience the police officers everyday work.

"Kulturell nedrustning" En studie av forskningsbibliotekens hållning till Bibliotekshögskolan i Borås 1969-1978
In 1972 a national higher education for librarians was started. Up until then different categories of librarians got their education separately. The aim of this Master's thesis is to explore the attitude towards this new education for librarians. The study will concentrate on the attitude of the representatives from the research libraries. Researchlibraries had, until 1972, recruted their librarians amongst Ph.D-level scholars.
Samhällskunskapsläraren och den interkulturella kompetensen : En deskriptiv studie av fem verksamma lärares interkulturella kompetens i det mångkulturella klassrummet
There are different ways of developing a second language. The purpose of this qualitative study is to investigate whether and possibly how music, focused on singing, can improve the development of Swedish as a second language. Through interviews with three vocal teachers, from three different schools in Sweden, and observations of one of the vocal teachers, information about how they work and think about the subject has been collected. The vocal teachers teach groups of second language learners by singing songs made especially for second language learning. The vocal teachers consider singing beneficial in the development of the pronunciation and improvement of the prosody, which affects the students? capacity to sound like a native Swedish speaker.
E-böcker och bibliotek : En kritisk diskursanalys av Biblioteksbladet 2005-2011
The aim of this two years master´s thesis is to examine discourses about electronic books in relation to libraries that occur in the Swedish library journal Biblioteksbladet by using critical discourse analysis (CDA). The thesis also aims to discuss changes in the discourse practice, and discuss the relationship between discourse practice and social practice in the field of library and information science (LIS). A main point of CDA is that language is a form of social practice that helps shape social reality. Furthermore the concept of ideology, as understood with-in CDA, brings understanding to the way discursive events help reproduce and transform social relations of pow-er. The text samples span from 2005 up to and including 2011 and were examined by using Norman Fairclough´s three-dimensional conception of discourse, which allows for interpretation of text on a linguistic, discursive and social level.The result of the analysis showed that there are several different discourses about electronic books and li-braries, none of which can be said to be particularly representative.
En filantrop måste ha långa armar ? Ett undersökande arbete om att illustrera svåra ord
A philanthropist needs long arms- An investigation on how to illustrate difficult wordsThe feeling of not understanding all the words that I read made me initiate the project of investigating the capacity of drawn images to increase the understanding of difficult words. I?ve been working with my own personal understanding and skills in illustration.My aim was to reflect on the function, composition and manner of my illustrations. I wanted the images to be clear enough to explain and function as a help for memorizing the words but also open enough to give them a new dimension. One of my conclutions is that my way of changing the original shape of a body in my drawings, by giving it new functions such as longer arms, helps me to explain the words clearer and deeper.
Identifiering av röjningsbestånd med hjälp av flygburen laserskanning
Bergvik Skog is one of the leading forest companies in Sweden who use airborne laser scanning for forestry information. They utilize laser data retrieved by the Swedish National Land Survey to describe the forest holdings and facilitate planning for thinning and final felling operations. However, the possibility to identify stands with clearing needs by using laser scanning data has not been tested in a large scale. The data used in the current study are field data from The Swedish National Forest Inventory in combination with laser data from the Swedish National Land Survey acquired in 2009. The collected data is used to find one or several laser variables that best describe the relationship of the field measured samples with clearing needs.
Undersökning av modulationsscheman för existerande bredbandsteknologier
In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.
