The trend in milk production is similar in Sweden and across the world; the farms are getting fewer but increasingly bigger. The costs for hiring workers are increasing, which results in more cows per animal keeper. Sensors can then be a great tool for keeping track of animals which need special attention. With a reported decreasing fertility, sensors that can detect oestrus even at low levels can be especially helpful in bigger herds to pinpoint the cows that may be in oestrus. The number of farms with dairy cows that install AMS, Automatic Milking Systems, are increasing, and that also increases the need for sensors to control milk quality and composition when there is no visual control of the milk by a milker before milking starts.For the sensor data to be useful you have to have software designed to analyze and interpret the data to get relevant information that the farmer can use.

This paper describes how radiation affects the body, the somatic and genetic effect that can occure in exposure of ionizing radiation and how to protect yourself against it. How radiation affects the cells and why you can get cancer if you get exposed of a large amount of radiation is mentioned. Research after a threshold is mentioned and what Sweden does today to improve the radiation protection by laws and regulations. Explaining the atom, what radiation is and how the ionizing radation interacts with the atom. How backscatter affect the picture and the workers and how to protect yourself from backscatter is mentioned. Radiation doses, dosimetry and rules for those who practise radiation is shortly described..

ABSTRACTChlamydia and Chlamydophila are species of a family of bacteria (Chlamydiaceae) that cause a range of diseases, including conjunctivitis, in a variety of animals including pigs and humans. Some species cause zoonotic disease. This study examined the occurrence of Chlamydiaceae in samples taken from the lower eyelid conjunctiva in pigs with and without conjunctivitis. The study was initiated based on a herd investigation aimed to examine the experienced increase of conjunctivitis in some finisher herds. This study was conducted as a case-control study, by collecting samples from 62 case pigs (16-26 weeks old) and an equal number of controls, from three herds in Uppland, Sweden.

There are no reliable, objective and simple methods today for measuring pain in horses. The purpose of this study was to evaluate and describe measuring of mechanical nociceptive threshold (MNT) values with a pressure algometer in clinically pain free riding horses at the riding school of Strömsholm. In this study there were 24 horses. Tape recording and electromyelografi (EMG) was used in an attempt to increase objectivity in the examination. MNT increased with age, however sex and colour had no influence.

This study is about how changed light conditions induce dormancy in plants. It is divided in two parts. First a literature study where quantification of light, the concept dormancy, photoperiod and light quality are discussed. Second an experimental part, where the importance of light for sprouting capacity in root buds of perennial sow thistle (Sonchus arvensis L.) is investigated.In the science in how flowering in plants are induced the concepts short day/long day plants and light dominant/dark dominant are well-established. These concepts can also be applied to how light induce dormancy in plants.

This thesis investigates the relationship between economic growth and self-reported happiness in 45 European countries during the periods of 2011 and 2014-2022. In addition to economic growth, the effects of factors such as unemployment, health, and equality are also analyzed. Data has been collected from the World Bank and Our World in Data. To analyze these relationships, a fixed effects regression analysis and clustering are used, supplemented by tests for multicollinearity and scatter plots. The results of the study indicate that economic growth has no significant effect on happiness when our control variables are included in the analysis.

Bakgrund: Truppgymnastik är en relativt ung tävlingsgren inom gymnastik med ursprung från de Nordiska länderna. I Sverige är det den mest utövade formen av tävlingsgymnastik med flest rapporterade  skador i nedre extremiteten samt återkommande besvär i ryggen. Tester i syfte att förebygga skador är efterfrågade och få studier har utvärderat tester för idrottande barn och ungdomar.Syftet med studien var att beskriva en grupp unga truppgymnaster utifrån bakgrundsvariabler, och rörelsekontroll med screeningtestet Performance Base Matrix samt att mäta förekomst av muskuloskelettala skador under en period på sju månader. Metod: Nitton unga truppgymnaster (flickor,7-9 år) genomförde screeningtestet Base Matrix i syfte att bedöma deras rörelsekontroll vid låg respektive/ low threshold och hög belastning/ high threshold. Testerna analyserades visuellt och genom videoupptagning. Resultatet av testerna dokumenterades i ett protokoll som bearbetades on-line samt för beräkning av procentuell förekomst av sämre utförd test i form av svaga länkar.

The aim of this Master?s thesis is to investigate if the library can be a real partner for researchers in managing and dealing with their research information. In this study, six researchers have been interviewed about their problems with information management. This study uses the method Critical Incident Technique for the interviews with the researchers. This method focuses mainly on problems and what happens around those problems.

Denna rapport behandlar en undersökning av olika lastbalanseringsalgoritmer i Linux Virtual Server. Undersökningen har gjorts i ett webbkluster (Apache var webbservern som användes) med tre heterogena noder, där operativsystemet var den detalj som skiljde dem åt. Operativsystemen som ingick i undersökningen var Windows Server 2008 R2, CentOS 6.2 och FreeBSD 9.0. De faktorer som undersöktes mellan de olika algoritmerna var klustrets genomsnittliga svarstid vid olika belastning och hur många anslutningar som kunde hanteras av klustret, detta gjordes med verktyget httperf.Undersökningen ger svar på hur ett heterogent webbklusters genomsnittligasvarstid och arbetskapacitet kan skilja sig åt beroende på vilken algoritm som används för lastbalansering. Resultatet visar att den genomsnittliga svarstiden håller sig låg tills en hastig stigning inträffar.

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

Platelets are small fragments, but they are of crucial importance for the coagulation. The risk of spontaneous bleeding increases when the level of platelets falls below a thrombocyte particle concentration threshold value of 50 x 109/L. In those cases a platelet transfusion might be compulsory. Ongoing research tries to improve the quality of the platelets and to increase the safety of the method used. However, we still need to better understand which factors that affect how patients react upon platelet transfusion.

In Economic Geography, there has been a strong interest of how different forms of proximity impacts businesses. In addition, there is also a strong interest in business agglomeration, as a result businesses cluster together through physical proximity, networks and knowledge. In the development sector, there is a strong interest on how to best support the creations and growth of small enterprises.This essay emphasises on the business cluster formations in Katutura, a suburb to Windhoek the capital city of Namibia. It oversees the impacts of different types of cluster formations and their effects on the businesses. In addition, this essay will identify the main clusters in Katutura and state what makes them unique from each other and what is a common cluster feature.

Inom alla verksamheter och organisationer finns det idag någon form av informationssystem. För att effektivisera, förändra och stödja verksamheten har allt fler företag valt att anskaffa ett standardsystem som hjälpmedel. Tyvärr innebär detta även att ett antal problem kan uppstå. Ett av de mest kritiska problemen som bör försöka undvikas är utebliven användaracceptans. Syftet med detta arbete var att undersöka vilka insatser som bör vidtas i arbetet med att anskaffa ett standardsystem, för att förbättra användaracceptansen.
