Betydelsen av social rang på beteende och mjölknings­parametrer i ett automatiskt mjölkningssystem (AMS) :

The purpose with the study was to find a pattern in the behaviour of dairy cows which could be related to their social rank. A behavioural study was conducted at the University Cattle Research Centre (Kungsängen) in Uppsala, Sweden. The study included 12 lactating dairy cows, 6 high ranked and 6 low ranked. The cows were housed in a loose housing barn with an automatic milking system (AMS) to which they had access 24 hours a day. During the experiment the total number of cows in the barn was 46.

Framtagning av normalt referensintervall för RDW och retikulocyter på hematologiinstrumentet ADVIA 2120

Erythropoiesis is a complex and carefully controlled process which is mainly regulated by erythropoietin. Using flow cytometry cells in a blood sample can be analyzed one by one. ADVIA 2120 using flow cytometry for analysis of red blood cells (RBC) and reticulocytes. Red blood cell distribution width (RDW) is a component of the RBC method. RDW indicates size variation on erythrocytes and is measured as a percentage of the mean cell volume (MCV). By measuring the RDW anemia can be divided into makrocytic, microcytic or normocytic. Reticulocytes refract light more strongly than red blood cells because they contain some cellular debris. The number of reticulocytes in the peripheral blood reflects erythropoiesis in the bone marrow. The purpose of this project was that by approved methods to establish reference ranges for the parameters, RDW and reticulocyte counts.The individuals who participated in the study, n=124, were considered healthy and had varying ethnicity. Reference subjects had not donated blood the last six months and participation in the study was voluntary.The statistic evaluation includes examination of distribution, and reference ranges for both men and women were established using the 2.5:t and 97.5:t percentiles. The calculated reference interval for RDW was between 12.0 ? 14.3% and the calculated reference interval for reticulocytes was between 38.0 ? 112.8 x109 cells/L. The results showed a significant difference between males and females for the parameter reticulocytes was seen. The difference indicates that different reference ranges should be established for men and women (p<0,0001). No significant difference between males and females were seen for RDW (p=0,74) indicating that the same reference ranges can be used for both men and women. .

Visualisering av informationskvalitet : Utformning av kvalitetsindikatorer för Lantmäteriets Fastighetsregister

Fastighetsregistret (The Cadastre) is a large and important information sourcesupplied by Lantmäteriet (the Swedish mapping, cadastral and land registrationauthority). Fastighetsregistret provides geographical information about the 3.2 millionestates in use in Sweden. Fastighetsregistret has a large number of users who trustthat the provided data is reliable, but experience shows that the data can have varyingquality. As a user it is not always possible to access more detailed information inorder to assess to what extent the data in Fastighetsregistret is reliable.The purpose of this master's thesis is to investigate the possibilities of a system with agraphical user interface that present, classify and visualize the quality of the data inFastighetsregistret. The defined user group for this suggestion is internal users atLantmäteriet who have a good understanding of Fastighetsregistret.

Unga grisars sociala beteende : hur uppfattar de varandra

Studies on wild boars have shown that piglets at 10 to 12 days of age can be introduced to pigs outside the litter without fighting. In today's production systems, the litters are kept in separate pens until weaning. At that point, the litter is divided and the piglets are placed together with piglets from other litters. This usually leads to aggressions among the piglets and may cause stress. This literature review aims to find out how piglets perceive other pigs in their surroundings.

En ny forntid? : ? förändringar i basutställningar om forntiden 1972-2005

The purpose with this thesis is to study how the arranging of archaeological objects in permanent exhibitions has changed over time. To find out about this I have been analysing three museums with prehistorical permanent exhibitions. The exhibition at Statens Historiska museum was produced in 2005, Nationalmuseum in Köpenhamn was produced in 1972 with additions from 1988 and 1995 and, finally, Malmö Museer exhibition which was produced in 1977. These exhibitions have been compared to analyse developments during the last 30 years. The result shows that there are different ideals within the exhibitions.

Hypotermibehandling efter hjärtstopp : Kognitiv och fysisk funktion samt självskattad hälsa efter 6 månader relaterat till tidsåtgång i vårdkedjan och primär hjärtrytm

AbstractAim of the study: Aim of the study was to investigate whether there were any connections in time between different parts of care in patients with cardiac arrest and hypothermia treatment and cognitive and physical function six months after cardiac arrest and to investigate neurological outcome related to primary registered cardiac arrest rhythm after six months and if there were any changes in cognitive and physical functions as well as self-related health between discharge from hospital and six months after cardiac arrest.Method: The study included 39 patients admitted to three Swedish hospitals between 2008-2011. Cognitive and physical function was evaluated with Cerebral Performance Cathegory, CPC completed with Mini Mental State Examination, MMSE for cognitive function and Bartels Index, BI for physical function and Euroqol-VAS for evaluating the self-related health.Result:  A significant connection was shown between time to start hypothermia treatment and BI, patients with longer time showed improved physical function after six months.Majority of the participants (66,7 %) had Ventricular fibrillation/Ventricular tachycardia, VF /VT, as primary registered cardiac arrest rhythm and in this group CPC and BI was significant better compared with the asystole /Pulsless Electrical Aktivity, PEA group.CPC, MMSE, BI and Euroqol-VAS were all improved over time.Conclusion: Participants with VF /VT as primary registered cardias arrest rhythm had significant better cognitive and physical function 6 months after hypothermia-treated cardiac arrest compared with participants with asystole/PEA as primary registered rhythm. This shows the importance of access to defibrillators in public places in the society and in hospitals and optimal education of lay people and medical staff. Cognitive and physical function and self-rated health improves over time, which might be a very important reason to convey patients, relatives and medical staff to continue cognitive and physical rehabilitation. Keywords: Cardiac arrest, hypothermia, cognitive and physical function, wellbeeing.

Känslighets- och osäkerhetsanalys av parametrar och indata i dagvatten- och recipientmodellen StormTac

Three methods of sensitivity and unceartainty analysis have been applied to the operative stormwater- and recipient model StormTac. The study area is the watershed of lake Flaten in the municipality Salem. StormTac?s submodels for stormwater, pollutant transport and the recipient are cosidired. In the sensitivity assessment, the model parametres and inputs were varied one at a time by a constant percentage according to the ?one at a time? (OAAT) method and the response of the outputs were calculated.

Undersökning om spelares uppfattning om latency i realtidsstrategispel

In this study we examine how much latency is required in an RTS-game (Real-Time Strategy) before the player quits the game. In the study latency is simulated in the games Age of Mythology and Starcraft: Brood War with the program WANem, and then the testplayers are asked ?Do you want to quit because of latency??. This data is then gathered and compiled into graphs to show the results. These results show that the limit for when players want to quit differs between the two games and that there are two factors that play into this.

Effektivisering av asfalttransporter : Enhetligt arbetssätt för styrning och tidsskrivning av asfalttransporter

The cost of transportation has strongly increased in the recent years, transportations which are a major part for the construction companies.

Clover (Trifolium spp) gamefields : forage production, utilization by ungulates and browsing on adjacent forest

Wildlife is a valuable and renewable resource that promotes economical, ecological and social values. These values are important for developing and maintaining many rural societies. However, growing ungulate populations have led to increased browsing pressure on valuable forest trees and crops. Previous studies have proposed supplementary feeding and gamefields as potential methods for controlling the ungulate foraging and reducing browsing damage by providing other attractive food resources. However, quantitative estimates of potential biomass production of various gamefield crops and browsing pressure on the surrounding forest have been lacking.

Narrativ för arenaspel : att skapa ett narrativ till ett ?mutiplayer Online Battle Arena? koncept

In 2011, I and fellow student at Gotland University created a multimedia game. To fit the time constraints a ?vertical slice? was created. This means a small sample of the game is taken which allows the user to understand how the game works, and at the same time, get a visual demonstration of how the game is designed. The goal of the project was to create a narrative for stadium games in which the backstory is told as players interact with their surroundings.

Vad står det där, Fröken? : Läs- och Skrivinlärning, samt svårigheter som kan uppstå.

AbstractI have chosen to make a study of the learning of reading and writing, as well as other learning difficulties that may occur, in this research.My choice of subject is based on the realizations I made during my time as a student teacher; that each teacher has his/her own way of teaching reading and writing. Sometimes, however, learning difficulties occur, and this insight caught my attention. It made me think about the underlaying reasons and how we, as teachers, can bring attention to these difficulties. With these questions in mind, I recorded my observations based on a series of interviews and literary studies in an attempt to answer my questions. The resulting research emphasizes how important the actions from the teachers are, as well the importance of having variety in your lesson plan.

Utnyttjandet av ligghallar hos dikor och kvigor av köttras under vintern :

Cattle used for meat production can be held outside all year round and due to the legislation they should have access to shelters or other buildings for protection against the elements giving them a dry and clean bedding. There are different opinions concerning their need of protection and the question about necessity of shelters for cattle is of current interest due to a less profitable economy in meat production and the investment costs for shelters. The aim of this study was to acquire more knowledge about the natural behaviour of cattle concerning their use of shelters. The basis of the study was a series of questions regarding when animals choose to stay in shelters, if shelters were used less when they had access to protecting vegetation, how temperature and weather conditions affected the use of shelters and the influence of distance between shelter and feed. Behavioural studies was conducted at five different farms where six groups of suckler cows and heifers of following breeds and crossbreeds were observed; Aberdeen Angus, Charolais, Hereford, Scottish Highland Cattle, Simmental and the Swedish breeds SKB and SRB.
