Porcine viruses in Uganda : a study of TTSuV and PPV4 in wild and domestic pigs
Uganda has the largest pig population in east Africa, and most of the animals are owned by smallholders. Infectious diseases among pigs have a devastating impact on the livelihood of these farmers, which are dependent on the proceeds from pig rearing. In a metagenomics study of the wild pig species bushpig (Potamochoerus larvatus), the porcine viruses Torque teno sus virus (TTSuV) 1and 2 and Porcine parvovirus 4 (PPV4) were detected. TTSuV1 and 2 are ubiquitous in the world?s swine population, and PPV4 has been found in USA and China, but neither of them has been studied in Africa previously.
Registrering av faktisk närvaro i förskolan - vem berörs?
Every municipality in Sweden is responsible for offering its citizens adequate childcare. Parents hand in a preliminary schedule to the preschool for when their child needs to be in childcare, and based on this the preschool staff is scheduled. Some municipalities measure the actual time a child is in childcare. The essay idea comes from when I heard that one municipality was thinking of register the children's actual time in preschools. I started thinking on how to solve such a task.
Quantification of sleep in dairy cows in three different stages of lactation
The aim of this project was to quantify the total sleep time in modern dairy cows during24-hour periods and to investigate whether the total amount of sleep as well as timespent in different sleep stages varies between the dry period, early- and peak lactation.The distribution of sleep time between night and day was also examined. Furthermore,correlations between sleep and lying time, fluctuations in body temperature and heartbeat were included in the aim. Eight dairy cows of the Swedish Red breed were used inthis study, which was carried out between June and September 2010. In order toquantify sleep non-invasive electrophysiological recordings were performed.Simultaneously with collecting sleep data, body position and body temperature werealso recorded. No heart rate data was obtained due to difficulties of maintainingelectrodes for heart beat measurements attached to the skin.

"Alla människor har en fasad och man vet aldrig vad som döljer sig där bakom" En undersökning om hur det går att påverka elevers attityd till lyrik genom undervisning
The study is ethnographic and the collected material consists of questionnaires, interviews andconducted practical exercises. The purpose of this study is to examine whether it is possible tochange boys attitude to poetry and poetry teaching through practical exercises. The questionswhich the study is based on concerns how frameworks for tasks can enhance the creativity ofthe students, the standards students have as a reference point and what attitudes boys have topoetry. The study shows that students feel that they are more creative if there is a frameworkfor the task, it has also been shown that boys do not have any special attitude to poetry,because they do not know what the word means. One of the most important results in theresults section is that boys have a positive attitude to poetry as long as the teacher gives themthe right tools to work with..
CAP KC3-12 : Design and finite element analysis
In offshore oil production FMC Subsea systems use a product called cap. The cap´s mainly task is to protect hubface and seal areas on inboard hub against dirt, corrosion and mechanical damage under installation of a subsea system. A new model of a cap has been designed and analysed using finite element method. The model is called KC3-12 and has a new function, emergency release, which is a backup method for the ROV (remote operated vehicle) to release the cap from the hubface when it is placed under water. The cap KC3-12 was found to fulfil the criteria under the test load pressure, according to ASME VIII, div2.
Öppna och slutna frågor i en jämförande studie : En studie i hur arbete med öppna/slutna frågor påverkar elevers förmåga till perspektivbyte i tid och rum.
Vi har i vår forskning belyst hur elever upplever arbetet med öppna respektive slutna frågor. Vi har framförallt tittat på hur arbetet med öppna och slutna frågor haft för inverkan på elevers möjligheter till perspektivbyte i tid och rum. Öppna frågor har i vår forskning varit lika med hög frihetsgrad medan slutna frågor är lika med låg eller ingen frihetsgrad. Vi har i vår forskning jämfört resultatet av en essäuppgift från två grupper med elever från årskurs 6. Dessa två grupper har innan uppgiften vägletts i temat ?En resa till Kina? i var sin experimentlektion.
Diurnal rhythm of the savannah elephant (Loxodonta africana africana) in Maasai Mara National Reserve, Kenya
Elephants are hindgut fermenters, which affects their diurnal rhythm. To reach their nutrient demands, elephants must eat almost constantly throughout the light part of the day. Sexual dimorphism may also affect their behavioral patterns. To understand the elephants' normal living habits and foraging behaviour, we conducted a pre-study in the Mara Triangle, the north-western part of the Maasai Mara National Reserve. Each of four to six observers randomly chose a focal animal within the group of elephants by the criteria that they were adults and visible.
Dialog om staden : En studie om medborgardialogens roll och betydelse för stadsplaneringen i Nacka kommun
This master thesis explores the nature of public participation as a central and most current subject in the field of urban planning. A first impression exposes a seemingly unanalyzed consensus on the values and benefits which public participation provides the process of urban planning. The city may be a concern to all its inhabitants; hence knowledge and opinions of the local public are of great importance for the urban development. But is there really something new to these assumptions, and are the advantages of increased public participation in urban planning always obvious? By using action research as a main method, I have put myself into the context of the Swedish municipality of Nacka and their projects dealing with the development of public participation.
Kontrollerad gjutprocess för renare stål
In a multi-year project at Swerea Swecast AB studies on influence of dissolved gas on inclusions have been made. The knowledge about these parameters could be used to increase the quality of the final steel casting. The purpose of this thesis was to closer examine the impact of the oxygen level on inclusions.The questions asked were:? What was the amount of inclusions at different levels of oxygen?? What was the size of these inclusions at different levels of oxygen?? What does the inclusions consist of at different levels of oxygen?This was studied by measuring and sampling, sample preparation and microscopic analysis using an optical microscope and a scanning electron microscope (SEM). Measurements and sampling was performed at Smålands Stålgjuteri AB in Eksjö and at Swerea Swecast AB in Jönköping.

Behandlingsvåtmarkers reningseffekt på aktiva läkemedelssubstanser under vinterförhållanden : En studie av fyra svenska våtmarker för avloppsrening
Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.
Den ultimata träningsmetoden?
Crossfit is a recently developed form of training which is based on a number of functional resistance exercises performed at high intensity, often to the point of muscular failure. Crossfit has since its introduction 30 years ago, reached vast popularity all around the world, including Sweden. Its practitioners considers Crossfit to be an effective training method for achieving a functional and total trained physique thru improvements in VO2max, muscle strength, endurance, balance and speed. Few scientific studies has been published in the subject which is why this study sets out to examine the effect of Crossfit on VO2max (measured with Åstrands submaximal cyclingtest), maximal strength capacity in lower- and upper body muscles (measured with 1 RM tests in bench press and leg press), rapid strength capacity and strength endurance capacity in upper body muscles (measured with push-up test in 30 seconds) and explosive strength capacity in lower body muscles (measured with sergeant jump test). Five women with an average of 33(±5) years of age all new to Crossfit, performed these tests at two separate occasions with a training period of four weeks consisting of 12(±3,67) Crossfit sessions in between.The result showed a significant improvement in the maximal strength capacity of the leg extension muscles (p=0,025).
OPAC - på Märsta folkbibliotek
The purpose of this Bachelor thesis is to examine how user-friendly the OPAC of the Märsta public library is considered to be.Theoretical basis are HCI and Allwoods definition of usability. Issues are: Is the OPAC suited to its task? Is the OPAC user-friendly? How well does a user accept the OPAC? and What degree of competence is shown by users of the OPAC? The source material consists of six interviews in the form of .avi files. The method I have chosen is qualitative semi-structured interview form. The result is that, based on Carl Martin Allwood?s defini-tion and with exception for the using of help-resources, the usability of Märsta?s library OPAC can be considered less good..
