Clinical and subclinical mastitis in dairy cattle in Kampala, Uganda
Dairy farming in Uganda provides a source of food, employment and income. Previous studies have revealed high frequencies of bovine mastitis, a costly disease for the dairy farmer. The aims of this study were to investigate the bacteriological panorama in milk from udder quarters with clinical (CM) and subclinical mastitis (SCM) and to determine the antimicrobial susceptibility in staphylococcal isolates. Further, we intended to establish the prevalence of subclinical mastitis and to investigate some environmental factors and animal properties that might influence the frequency of mastitis. For CM, farmers made contact with the members of this study when recognizing an animal with CM.
Funktionsupphandling av solelanläggningar
This thesis aims to contribute to improved functional procurement of photovoltaic systems, PV systems. Functional procurement means that criteria concerning a function are set rather than specifying technical details or products. Possible advantages and difficulties in using functional procurement have been analyzed by interviews, simulations and a case study. Electricity production and surplus production for different scenarios have been simulated via MATLAB. The MATLAB script was also used to generate rules of thumb on feasible solar fraction for six different load profiles; a church, a farm, a car mechanic, an office, an industry and an apartment building.
?Man känner sig otillräcklig? : En kvalitativ studie om fem lärares upplevelser av att undervisa nyanlända elever i ordinarie klasser
The purpose of this study was to examine how teachers in primary schools experience the situation of teaching newly arrived immigrant pupils in their regular classes and also how they plan their teaching for these pupils. The empirical study did intend to answer the following two questions; how do teachers experience the situation of teaching newly arrived immigrant pupils in their regular classes? How is teaching of newly arrived immigrant pupils in regular classes being formed? A qualitative method was used in the form of interviews with five primary school teachers from two different schools. The overall perspective I have assumed in this study is the sociocultural perspective, but I have also taken up a second language perspective and an intercultural perspective. All the teachers in the study have described their experiences of teaching newly arrived immigrant pupils in terms of difficult, tough and demanding at the beginning, but nowadays somewhat easier.
Hastighets- och positionsinterface för motorer
The environmental requirements and laws on combustion engine emissions are very tough today andthey will become even more stringent in the future. To achieve these requirements there are highdemands on the control systems for these engines. An improved precision in the measurement of anengine's speed and position gives the electronic control system an even better timing when it comes tofuel injection and ignition. This makes the engine more fuel efficient, reducing the emissions. This thesisis part of a collaborative project between Hoerbiger Control Systems and subsidiaries.
Datorbaserad examination: En studie om användarhinder och systemacceptans bland lärare
The aim of this thesis is to examine how teachers use computer based assessment in their work and what user barriers they experience while working with computer based assessments. The result of the thesis is meant to provide an understanding of which factors affect the use of computer based assessments and how a company who provide computer based assessments applications can increase the rate of use amongst teachers.To investigate this, the author examined a company in Sweden who provide a computer based assessment application for both universities and high schools. The study was carried out at two different schools, a university and a high school, both located in Stockholm. In total nine teachers were interviewed. The author also conducted observations at the company whose computer based assessment application was examined.The author?s findings suggest that a lack of functions within the application and lack of costumer support from the company all negatively impacted the teacher?s use of the application.
Webbaserat resultat och uppföljningsprogram för idrottsförening
Students at the School of Engineering at Jönköping University have on behalf of the swimming organization ?Nässjö Sim och Livräddningssällskap? conducted research on how to monitor and evaluate swimmers and swimming groups in a simple and efficient manner with a focus on usability and user friendliness. Since no system existed that could meet these requirements, the client had a desire to tailor and develop such a system. The purpose of this work was to develop a system that would work as a tool to be used by coaches and swimmers alike and allow them to eventually follow the development of swimmers and swimming groups. The organization also wanted to have the ability to create tests and exams, both for land and water training, register these in the system and in a structured way know which swimmers took and passed these.For this thesis, the following questions functioned as a framework for progress.UsabilityHow to design a usable system and what is required?SystemWhat type of system is best suited to meet the client's requirements and preferences?Competition resultsHow can one retrieve all the competition results for swimmers of Nässjö SLS?DatabaseWhat type of database is best suited to easily share data with an external existing database?Usability has been the main focus throughout the project.
Ekonomi i Passivhus : En studie av två verkliga byggnader
The aim of this report was to investigate the economy of passive houses. The work was focused on economy in total and on the economy of different components such as windows, insulation, heat exchanger and the air tightness of the climate shell. No attention was paid on the comfort factor or to the impacts on the environment.Two houses, aspiring to be passive were chosen; A big one and a small one. Hence, comparisons considering the size of the building have been possible to do as well.The comparisons were made by calculating ?break even? between two concepts; passive and BBR- concept.
Alternativ uppvärmning av reningsverket på Utö - En studie av energibesparingsmöjligheterna i syfte att minska uppvärmningskostnaderna
The projects objective is to find an alternative method of heating (the current method being via electric heating) the sewage treatment plant on the island Utö in Stockholm?s archipelago in order to reduce the energy consumption and ultimately the cost for heating the plant. The project is given by ?Skärgårdsstiftelsen? (The Archipelago Foundation) and is a part of the larger EU-project ?Green Islands?.A model for the plants total heating demand is established in order to get a good perception of how much money can be saved using alternative heating methods. The heating demand model gives an annual heating demand of approximately 32 500 kWh and a maximum heating power demand of around 24,7 kW.
Interorganisatoriska interaktioner inom Inkubatorer : En studie om kunskapsutbyte och inkubatorsystem
BackgroundIncubators are important facilities for economic growth in society. The main purpose of incubators is to accelerate knowledge intensive firms onto their market by both providing resources and an entrepreneurial environment.Problem Companies within incubators are encouraged to share knowledge and experience with each other with the goal to stimulate development and invention of new technology. This exchange involves interaction on an inter-personal and inter-organizational level. Incubators need to create an open and transparent environment in order to enable this exchange on both levels.Purpose The purpose of this study is to enhance the understanding of how knowledge and experience exchange occurs within the context of incubator systems. By understanding how incubators can capture knowledge and learn from the incubator process, this study can contribute by insights of how the incubator process can be further improved.Method This bachelor thesis is written from an abductive approach and is based on a qualitative case study of Ideon Innovation in Lund.
Framtagande av kravspecifikation för standardsystem
There are several methods and models within the areas of software engineering on how to proceed during a software development process. For each of these methods and models there are benefits and drawbacks, depending on how you choose to look at them. A difference of principle between the different models is that they either advocate iterative development or not. In parts of software engineering one makes use of different methods depending on which is most fitting in a specific situation. There are several methods on how to recieve more qualitative data from the end-users during the requirement collection, but the reappearing pattern is still user centric participation, which means that the user participates more actively in part of or the entire development process.
Uppföljning inom ett vårdvalssystem - En fallstudie av uppföljningen av husläkaruppdraget i Stockholms Läns Landsting
This study aims to examine the effect the evaluation system used by the Stockholm County Council, has on how the healthcare providers themselves conduct the evaluation regarding their own operations. This is done through a qualitative case study of the evaluation systems of the Stockholm County Council and of four primary healthcare producers concerning one primary healthcare contract. The evaluation systems were analysed using Merchant and Ver der Stede's (2007) framework for different types of control. In order to give a more detailed picture this framework was complemented with different types of performance measurement. The evaluation that the Stockholm County Council conducts was found to have little influence on the providers own evaluation with the exception of the quality indicators that are rewarded with a monetary bonus..

Utvärdering av fosforläckageefter stallgödsling med hjälp av lysimeterteknik : Evaluation of phosphorus leaching aftermanure application using lysimeter techniques
Based on laboratory studies with lysimeters, the concentrations of dissolved reactive phosphorus(DRP) and particulate phosphorus, which is the main part of other P (OVRP), has been studied inpercolating water. The experiment was conducted through irrigation of small soil columnscontaining clay topsoil from an experimental field in Västergötland. Three rain simulations wereconsecutively performed. DRP concentrations in the percolating water ranged between 0.2 - 0.3mg·Lclearly related to the phosphorus concentration in the soil, measured in a soil extract ofammonium lactate (P-AL). Concentrations of OVRP were relatively low and ranged between0.12 and 0.16 mg·Lwas not proven and the experiment may reflect how a relatively slow percolation of water mayrelease DRP.
Går sociala risker att visa på en karta? Social rumslig riskanalys för Göteborgs stad
This essay deals with risk management and social risks, which have received increased attentionin recent years. Methods for dealing with social risks, for example within local Risk andvulnerability assessment (RSA), are currently under development. The purpose of this paper is toexamine if and how social risk can be quantitatively assessed and mapped using GeographicInformation Systems (GIS). The definition of social risk that the essay is based on states: "Theprobability of unwanted events, behaviors or conditions originating in the social conditions thathave a negative impact on the objects that are worth to preserve.? A number of social riskindicators that can be used for a spatial analysis have been operationalized based on thisdefinition.
?Jag tycker bara att jag gör vad jag vet att jag kan göra? : en undersökning av en webbaserad bibliotekskatalogs användarvänlighet utifrån användarnas perspektiv
The purpose of this Master's thesis is to examine whether a web-based library catalogue is to be considered user-friendly. We have examined this from a user-perspective by interviewing users of a web-based catalogue at a public library. In order to get a picture of the user-friendliness of a catalogue, the thesis is centred upon the following questions: How is a web-based catalogue used? What problems do the users experience? How is the catalogue perceived by its users? Since the producers of these catalogues now are taking into account the research upon human-computer interaction, we are also interested in finding out whether a web-based catalogue is more user-friendly than a more traditional OPAC. We do this by comparing the results of our examination with earlier studies of OPAC use.
