Användandet av samlingsprover för att bestämma besättningsstatus för smitta med Dictyocaulus viviparus hos förstagångsbetande nötkreatur :
Infection with the bovine lungworm - Dictyocaulus viviparus - is occasionally a problem in Swedish cattle herds. The infection could act in synergism with other infections such as Corona virus to create a poorer welfare and productivity in cattle. Studies have shown that a diagnosis can be made with both the Baermann method and with an ELISA. In Norway diagnosis of BVDV on a herd level is attained through pooled serum samples. The question was raised whether pooled serum samples could be used in a similar fashion to attain status on a herd level for lungworm.
En deskriptiv studie av SWAFRAP, AJS 37 planeringsprocess på F 21
I en omvärld som ställer allt högre krav på delaktighet kom ett uppdrag 2000-03-30 till Norrbottens Flygflottilj, F 21 som på nio månader skulle sätta upp ett nytt internationellt förband. Om förbandet kallas ut blir det första gången sedan sextiotalet som Sverige fullgör tjänst med krigsflygplan utomlands. Swedish Air Force Rapid Reaction Unit, SWAFRAP AJS 37 skulle ställas i 30 dagars beredskapDenna uppsats syftar till att beskriva och analysera den planeringsprocess som har genomförts på F 21 ur de traditionella perspektiven problemformulering, genomförande och utvärdering avseende detta nya förband.Undersökningen har genomförts som en fallstudie på F 21 och avgränsats till AJS 37. Planeringsprocessen har studerats genom intervjuer av chefer inom SWAFRAP organisationen.Studien pekar på att processer av detta slag är ytterligt komplicerade och kräver mera forskning om vi skall lyckas förstå alla ingående komponenter och deras interaktion..
Livskvalitet och rehabilitering för män och kvinnor med diagnostiserad hjärtsjukdom : en litteraturstudie
The aim of the study was to describe how women and men with diagnosed heart disease experience their health-related quality of life and what differences there is between genders in their quality of life and also describe problems after receiving the diagnosis. The study also aimed to describe rehabilitation of patients with heart disease. The study was a descriptive literature study based on scientific articles. It emerged that both women and men with heart disease experienced lower quality of life compared to normative data. There was a significant difference between women and men both one year and three years after receiving the diagnosis heart disease, which showed that women experienced lower quality of life than men.
Omvänd aktiesplit : överlevnad eller kosmetik
The shareholder is supposed to be indifferent if one share costs 100 SEK, or 10 shares cost 10 SEK each. In an efficient market, shares should be valued directly to new expectations as a result of the announcement of the reverse split. We investigate whether abnormal returns incur surrounding reverse split and if owner structure change.One reason for the reverse share split is that most companies have plans to imple-ment other company?s specific events in order to survive rather than to change the price range to a more attractive level. We found a negative return in the ex-day at 8,1 per cent.
Har analytikernas roll på aktiemarknaden blivit mindre relevant: En studie av analytikernas påverkan på aktiers avkastning
The purpose of this thesis is to investigate if the stock market reacts differently to accounting information, depending on the stock market climate. The study focuses solely on stocks listed on the OMX Stockholm 30 during each year from 2005 to 2009. By applying the concept of Earnings Response Coefficient we can estimate how the market reacts to accounting information. The dependent variable in the equation is the market reaction on unexpected earnings, in the study described as the abnormal return on stock. For quality purposes we measure this on a ±1,5,10 and 20 days basis.
Kloning av möjlig promotorsekvens uppströms kloritdismutas i Ideonella dechloratans.
Perchlorate and chlorate are naturally occurring in the atmosphere, from here it sediments into groundwater and soil. The pollution is increased by discharges of perchlorate and chlorate from agriculture and paper mills. Bacteria capable of reducing perchlorate and chlorate to chloride and oxygen can be used to get rid of these contaminants. However an anaerobic environment needs to be sustained in order for this reaction to be used. For this reduction to work in an aerobic environment as well, a greater knowledge of the reducing enzymes, regulating factors and their corresponding genes is needed.
Jämförelse av vertikala krafter mellan hov och underlag vid nedsittning och lättridning i trav hos häst :
Equestrian sports and the interest in horses have existed for hundreds of years. It is only in the last thirty years the technological development have enabled closer studies of equine locomotion. The production of both soft- and hardware that manages to capture and analyze the fast movement of the horse has resulted in a large increase in locomotion research.
Even though the interest in horses and the different disciplines they compete in is great, there is a small understanding in how the rider influences the movement of the horse in different types of training.
There are several studies available where horses moving freely without the influence of a rider have been studied. What happens with locomotion and ground reaction forces when a rider and equipment are added is not well studied.
The objective of this study was to investigate if there are any differences in the ground reaction forces between sitting and rising trot.
The study contained seven horses. Six Grand Prix dressage horses and one dressage horse competing at intermediate level.
Det svenska vetenskapliga biblioteksväsendet under 1950-talet
After W.W. II the Social democratic government wanted to modernize and rationalize the Swedish society. The university system was reformed[INS: :INS] to support growth of industry and science. But the reform did not reach Swedish academic library system and it was not well organized. The aim of this thesis is to analyze the reaction of the Swedish academic libraries to the new era in the framework of ideological criticism.
När bonderörelsen skapade partipolitik : Idéer och politik i Bondeförbundet under perioden 1910-1959
The aim of this bachelor´s thesis ist to analyze the idea progress in the party programs in the swedish Centre-party during the time 1910-1959. The progress in the party program is compared with the evolution of society during the same period.The bachelor´s aim is also to analyze how each new program is described in newspapers, two newspapers were chosen to make the comparison; Arbetet (a social-democratic newspaper), and Skånska Dagbladet (a centre-party newspaper). The result shows that the party in the beginning was conservative and against both capitalism and socialism. The start of the party was a reaction against the new electionsystem which was introduced in Sweden in 1909.The party took a clear standpoint for the Swedish farmers, but after 1933, they were standing for the whole countryside. In the 1940´s and the 1950´s the party became more like a social liberal party rather than an agrarian party only for the farmers.The party programs are not given much space in the two newspapers.
Komplikationer vid behandling med cochleaimplantat
Cochlear implant has become a common treatment for people with severe hearing loss. As the field of cochlear implants is developing rapidly a larger group of patients will be implanted. Therefore, it can be of interest to identify which complications are most frequently occurring. Objective: The aim of this study is to identify and present the most common complications in cochlear implant treatment and to identify surgical issues that have to be addressed during implantation. Method: A review of retrospective case studies regarding complications has been made.
Är det möjligt att använda SCR-rening av rökgaserna vid inblandning av avfall i biobränslet?
Waste appears to be a low-cost fuel compared to biofuel. This Masters thesis was conducted for Vattenfall Utveckling AB and deals with how waste in the fuel affects the performance of a SCR-catalyst. Different mechanisms of deactivation were surveyed, focusing on the poisoning mechanism. A literature study was carried out, which was used as a reference when analysing the results.Small samples (9x2x2 cm, 64 pieces) cut out from a full-scale unused honeycomb catalyst were exposed up to 1500h in two different combustion plants, Johannes in Gävle (co-combustion) and Högdalen in Stockholm (waste-combustion). The activity was measured mainly at 300°C but also at 250, 350, 375 and 400°C.

Vad de säger när de säger sina namn : En läsning av det subversiva anspråket utgående ifrån produktionen av författarnamnet Lidija Praizovic?
This thesis examines the way that subversivity is produced in relation to the name of the author, as understood by Foucault, and what potential for ressistance that can be glimpsed there. This from the reading of three text that in different ways relate to that theme.Firstly, throught the reading of "Isis mamma a?r genusvetare, skribent och konstna?r, min mamma a?r f.d. sta?derska, kokerska och dagisfro?ken, numera fo?rtidspensiona?r med diagnosen fibromyalgi" by Lidija Praizovic?, a text that actively work with the internal production of different exteriorities.

VD-karusellen : En eventstudie om en VD-avgångs påverkan på marknaden
The goal of this study is to examine how the market reacts when information about the exchange of a CEO becomes public. It also examines factors such as gender and whether the departure was voluntary or not, discerning if the market behaves differently concerning any of these aspects.To achieve this, the study was performed using an event study. The selection consisted of 48 companies on the Stockholm Stock Exchange, who had during the years 2005 to 2008 underwent a change in leading management. These units were submitted to hypothesis tests, to determine if an abnormal return was attained during the event window. The tests were performed on the units as a whole, and divided up after gender and whether the departure was voluntary or not.The results of the study show no statistically significant abnormal return caused by the announcement of a CEO exchange.
