?Whatever he discovers in creatures he guides to the Creator? : En studie om hur vi kan förstå St. Franciskus som miljömedveten, A study of how we can understand St. Francis as being environmentally conscious
This study investigated how we can understand St. Francis as environmentally conscious. The study also presents where those elements can be found in St. Francis own documents and from documents that describe St. Francis.
Visuell informationshantering i tunga fordon : Behovsanalys och förslag till förbättringsåtgärder
The flow of information in road vehicles intensifies as new techniques develop. Informationsources such as cell phones, navigation equipment and radios demand the driver?s attentionwhile he or she must stay focused on the road to perform a safe driving. Today the visualinformation inside the vehicle is mostly located on the dashboard, which forces the driver tolook down when shifting attention between the environment outside and the informationinside the vehicle. One way to avoid this is to useHead-up Display (HUD), a technique thatprojects information in the visual field of the user.This master thesis has been performed in cooperation with Scania CV AB, a world leadingtruck producer.
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.
Deltidsarbetandes företrädesrätt till högre sysselsättningsgrad
During the 20th century Sweden faced an increased proportion of workers registered as part-time unemployed, especially in the care sector. However, due to many valuable efforts, aimed at solving the problem of part time unemployment and political decisions, the number of people who are part-time unemployed has declined since the late 20th century. We have investigated part-time workers preferential right to extending their working hours. According to Section 25 a of the Employment Protection Act, part-time employees who have submitted an interest in increasing their working hours has a preferential right to increased working hours, with the assumptions that full-time employment with the employer will meet a labor need that the employee has sufficient qualifications for.Qualitative interviews have given us information about how Karlstad Community and a private care company deal with part-time unemployment and their workers preferential right to extending their working hours. We have found that people who work for Karlstad Community have an opportunity to choose their number of workings hours, thanks to a political decision made in Karlstad Community, aimed at solving the part time unemployment in the care sector.
Western på ett nytt sätt : NO COUNTRY FOR OLD MEN som western?
This addresses the problems when a film doesn?t easily fit in to one specific genre. Using No Country for Old Men as an example the study analyses the film from a Western perspective. Is it possible to say that it is a western? To determine that, I compare a number of acknowledged westerns, on the basis to list a number of generic conventions.
Kvantitativ studie om knappsatsdesign och knappstorlekars påverkan på träffsäkerhet
A mobile testing application using Unity was developed to analyse what impact button sizes and button layouts has on the accuracy of touch as well as the time to finish a labyrinth. This was tested on a Nexus 4 phone. 28 users navigated a small object through a labyrinth in which they collect keys to open the door to the exit. Each participant did the test 6 times with different combinations of button size and button layout each time, done in a random order. Hits, misses, completion time, order of button size and order of button layout was collected and then visualized using R.
Utveckling av processparametrar inom en hårdmetallindustri
This report analyzes and examines a hypothesis for finding a method to optimize thelength of the delubrication process time based on a total charge weight. The work hasfocused on the holding time for delubrication and the total charge weight.An important step in the manufacturing chain of cutting tools is when the greenbodies undergo the sintering process. Today, the delubrication step has the sameprocess time independent of the total charge weight. An implementation of a methodto adjust the delubrication process time would give more consistent quality of thecutting tool´s internal characteristics but also reduce the time course of the sinteringprocess. In the present project two methods for this goal were tested, thedevelopment of an algorithm and a weight interval subdivision with associateddelubrication process times.During delubrication a pressure increase is observed due to the decomposition of thePEG in the powder mixture.
Scintigrafisk undersökning av esofagusmotilitet hos häst :
Scintigraphic examination of the esophagus has for some time been the method of choice for the study of motility dysfunction in humans. The method has not yet been described for horses hence the lack of reference values for passage time for a bolus through the esophagus in healthy subjects. The purposes of this study were to measure passage velocity and time for a bolus to pass through the esophagus in healthy subjects, as well as to evaluate the reproducibility of the method. Eight warm-blooded trotters were used in the study. The horses were sedated with a low dose of Acepromazine prior to onset of the study.
EN KONSTRUERAD SITUATION ? I EN FORTSATT TANKEPROCESS KRING KÖN OCH SEXUALITET
ABSTRACTThe purpose of this essay is to investigate possible questions generated by theperformance/installation Har hon inget vettigare att göra? Du då. Har du inget annat att hitta på än att ståoch glo på henne? by the artist Elin Wikström. The Constructed Situation invites the spectator to be apart of a continuing process of thought.The subjective feeling makes an important insight to the work through methods of the aestheticsand the performative., mainly from Margaretha Rossholm Lagerlöf.
Prestation vid sönderdelning av GROT med olika typer av maskiner
There is a need for productivities data and data for different types of machines for comminution of logging residues. The lack of data and studies on GROT comminution makes it difficult to evaluate different chains for handling of residue fuels and make system analyses.Four types of machines with three different working principles were compared at six studies during winter conditions. Three to eleven trials during 9.5 to 30.7 minutes were made on each machine. Samples from the produced material at each study were sieved to determine the size distribution of the comminuted material. Samples were also taken from the studies for determination of moisture content.
Förlorad lönsamhet - en studie av PEAD:s förändrade egenskaper på den svenska aktiemarknaden mellan år 2000 och 2009
In this thesis we study the development of post-earnings announcement drift (PEAD) in the Swedish equity market from 2000 to 2009. By forming portfolios based on the stock price reaction to quarterly reporting we show that the characteristics of PEAD have changed. We demonstrate that negatively surprising companies show a positive drift during a holding period of six months sufficiently large to render the trading strategy unprofitable. This development holds from 2005 and onwards and these results contradict many a study which finds the same portfolio construction to be indeed profitable. We argue that this development is a trend that will not only affect our study but future studies as well..
Bibliotek i kristider: Perioden 1930-1945
In 1930 a new library reform came into force, which in reality was the beginning of the modern Swedish library. The purpose of this reform was to take measures to promote efficiency, for example to increase library co-operation. The Government grants were at the same time raised considerably. However, as early as in 1930, but especially the following year, the depression hit Sweden. The Government reduced the grants until the first half of 1936.
Inlösen eller extrautdelning?: En studie av sambandet mellan valet av kapitalåterföringsmetod och värdeskapande för aktieägarna
This thesis studies the stock price reaction around 68 announcements of special dividends and share redemptions on the Swedish stock market between the years of 2003 and 2007. We show that for the Swedish private investor, the tax effect of a share redemption is lower than that of a special dividend. Moreover, a share redemption could be interpreted as a signal of undervaluation. These two factors lead us to assume that the stock market would react more positively in connection to the announcement of a share redemption. We test this hypothesis through an analysis of the risk-adjusted abnormal return for the observations in the sample.
Idiopatisk epilepsi : en fallstudie
Epilepsy is a common neurological condition in dogs, being a common reason for
death in the statistics from the insurance company Agria in Sweden. Among the
different types of epilepsy, idiopathic epilepsy (IE) is the most common and is
characterized by the fact that a veterinary examination does not reveal a cause for
the seizures. This study has been conducted through studies of medical records
and interviews with dog owners. From a total number of 103 dogs that were
neurologically examined for seizures, 42 dogs met the inclusion criteria, being
classified as having idiopathic epilepsy. When the study was performed, 28 dogs
had died, while 14 were still alive.
Hur främjas läsutveckling? : Fem pedagogers tankar om hur de arbetar för att stödja elevers tidiga läsutveckling
A new curriculum, entailing news for teachers as well as students, was implemented in 2011. Among other things History has been given a more prominent position in that every student will now study the subject. Can this decision lead to history being used more in the future?The aim of this thesis is to study the new curriculum, Gy11, as well the Lpf94 and Lgy70, based on Klas-Göran Karlsson´s typology where the use of history is divided into seven different categories. I will analyze the curricula, looking at what different uses of history that can be discerned as well as what changes have been made over time.
