In the government's bill on infrastructure for 2010-2021, the government presents that road investments should be prioritized before investments in the railway. The grants for operation and maintenance of the railways are much higher then in the last government's bill. Furthermore the current founding of investment in railways is higher then for road investment which is in opposite of the bill on infrastructure's directives. Therefore the purpose with my thesis is to find which factors that can explain how come the government has chosen to take these actions. As a model to help me achieve my purpose I have been using a modified version of the DBO-theory, where the basic factors to explain an action is Desire, Belief and Opportunities.

The aim with this study is to prepare for a larger study, by gathering information about hunting enrichment, discuss which enrichment Parken Zoo in Eskilstuna have that are suitable to use in the larger study and report which observation methods that are used in other articles. In the larger study, the focus will lie on evaluation methods and measurable results. They have, during several years at Parken Zoo in Eskilstuna, developed different types of hunting enrichments for their carnivores, because hunting is a natural behavior that is hard to accommodate in captivity. The bigger project will integrate other zoos so that they can do a study on a larger group of animals, and because a lot of other studies in the same field only capture the results of few individuals. In this literature study you will read about the goals of enrichment, research that have been done on enrichment for felids and review several specific articles about hunting enrichment for felids..

Bakgrund: Bröstcancer är idag en av de vanligaste cancersjukdomarna och som har ökat konstant de senaste två decennierna. Årligen insjuknar cirka 7000 kvinnor i bröstcancer vilket motsvarar ungefär 15-20 fall per dag. Lidande, välbefinnande, att ingå i en vårdrelation, kommunikation och information är begrepp som ingår i en människas livsvärld. Begreppen beskriver hur en människa upplever sin egen värld och på så sätt även hur unik den kan vara. Med livsvärld menas den värld vi lever i och ständigt är omgivna av.

With numerous applications in both military and civilian life, the demand for accurate 3D models of real world environments increases rapidly. Using an airborne laser scanner for the raw data acquisition and robust methods for data processing, the researchers at the Swedish Defence Research Agency (FOI) in Linköping hope to fully automate the modeling process.The work of this thesis has mainly been focused on three areas: ground estimation, image segmentation and classification. Procedures have in each of these areas been developed, leading to a new algorithm for ground estimation, a number of segmentation methods as well as a full comparison of various decision values for an object based classification. The ground estimation algorithm developed has yielded good results compared to the method based on active contours previously elaborated at FOI. The computational effort needed by the new method has been greatly reduced compared to the former, as performance, particularly in urban areas, has been improved.

Bakgrund: Det är vanligt att patienter som ska genomgå generell anestesi och operation är ängsliga och oroliga preoperativt. Denna stress har en negativ inverkan på hela det perioperativa förloppet. Därför är det viktigt att anestesisjuksköterskan uppmärksammar dessa patienter och bemöter dem på ett förtroendefullt sätt. Syftet var att beskriva anestesisjuksköterskans erfarenheter av hur en känsla av trygghet och tillit kan förmedlas till vuxna, med preoperativ ängslan och oro inför generell anestesi och operation. Metod: Systematisk litteraturstudie som bestod av åtta kvalitativa vetenskapliga studier.

ABSTRACT The aim of this thesis is to illustrate how surgical operation theatre nurses perceive debriefing within emergency health care. The study has a qualitative design with semi structured interviews that have been performed with seven operating room nurses working in emergency health care. The strategic selection consists of professional operation theatre nurses working in emergency care at Uppsala University Hospital. The main goal of this thesis is to increase the understanding of debriefing and to highlight the need of debriefing after difficult or unexpected events in the emergency health care profession.The interviewed nurses perceive debriefing as an important way to develop the day to day work, but also as a way to unburden the staff at the time of bigger traumas. Even though the effect of debriefing is not univocally positive in the literature, the staff perceives that it reduces different kinds of stress.

Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.

This master thesis reviews advances in detection and diagnosis of static friction (stiction) in control valves. Control valves suffering from stiction results in oscillating control loops which in turn decreases both the process stability and reliability. Perstorp AB sees a necessity to automatically detect stiction in valves before the effects of the malfunctioning valves have become too severe. This thesis presents an introduction to maintenance, control loops and how stiction in valves can affect performance of control loops.A selection of methods presented in the literature are introduced and examined using normal operating data from the site in Perstorp. Common for all selected methods is their intuitive ideas and that they are based on normal operating data and minimum amount of process knowledge.

Försvarsmaktens förändring genom reformarbetet mot ett insatt insatsförsvar, har lett till ett fokus mot delvis nya uppgifter. Expeditionära operationer är en sådan uppgift, som innebär förändrade krav och förmågor på materiel och personal. Problemet, som uppsatsen vill belysa, är att vid planering och genomförande är taktiska uppgifter i operationsområdet dimensionerande i för hög grad. På det viset läggs inte tillräcklig kraft på hur förbandet ska komma på plats och hur bäst förutsättningar för uthållighet ska säkerställas över tiden. Det är därför angeläget att en noggrann analys genomförs i planläggningsskedet, så att egna kritiska sårbarheter kan identifieras.Syftet med uppsatsen är att undersöka vilka kritiska sårbarheter som är tydligast ur ett logistiskt perspektiv, vid en vald expeditionär operation.

Bakgrund: Postoperativ smärta är vanligt förekommande efter en genomgången operation. Den postoperativa smärtan kan leda till onödigt lidande för patienten. Vid en operation utsätts patienten för en större eller mindre ?skada?, där hud, muskler, leder och nerver skadas. Under den postoperativa fasen observeras patienten på olika smärttecken.

This thesis analyzes the effects of different fertilization strategies on forest management at Holmen Skog in Umeå district. Harvesting volumes, net present values and fertilization intensity are presented for each fertilization scenario. The planning reserve (percentage area older than minimum final felling age) was also analyzed in this study.The thesis covers the analysis of five different fertilization scenarios, varying in fertilization intensity, from no fertilization at all, to fertilization at every harvesting operation (thinning or final felling). A sub-study was also carried out so the reader in detail can see how the different fertilization scenarios affect individual forest stands of different nature. The analysis has been done with the planning tool PlanWise, which is an application of the Heureka analysis and planning system.

Abstrakt I den här uppsatsen undersöks hur ett narrativ kan drivas inom digitala spel enbart med hjälp av spelmiljön. Syftet är att få förståelse för vad miljöberättande behärskar som en självständig form av berättande och vad författarna kan göra för att uppnå detta mål. För att undersöka problemområdet genomfördes en spelproduktion där metoder framtagna under undersökningens gång applicerades. Produktionen testades av utomstående studenter i medieteknik och resultaten sammanställdes med reflektioner kring vad som uppnåtts och de metoder som applicerats. Undersökningen beskriver arbetsprocessen och metoder och visar hur dessa kan driva ett narrativ med en spelmiljö.

The purpose of this investigation is to compare the teaching in reading of three pedagogues in form 2 in three different schools from a second language perspective. Among other things it implies to investigate how the pedagogues think of teaching in reading and the reading field to be compared with if these fields are adjusted to a diverse cultural perspective. This investigation is carried out through observations and interviews. To compare the schools they have been picked out from the number of pupils and the number of second language pupils, that is 15 %, 67 % and 95%. The investigation also includes how the pedagogues weigh the pros and cons within reading and working methods.The further reading is built upon theories and previous research that have an attachment to the view of the sociocultural and the diverse cultural perspectives of teaching.

In 2009, the Swedish Basketball Federation started a Region U15 development project in order to change the structure of the regional organization to get into a more transparent and similar operations throughout the country. My purpose is to study the attitudes to the change among the region leaders in the regional operations and evaluate the change from an organizational perspective. The study is primarily based on the following questions: What are the experiences of the change process among the region leaders in the regional organization? How involved have region leaders been in the changing process? Which are the positive and negative aspects with the regional operation today? What can be done further to develop the regional operation and to what extent do the organizational change follow general organizational theories? In my study, a qualitative method was used in terms of interviews with 8 regional leaders to understand their attitude to the project and the changing process. To analyze the results of the region leaders ?responses, a transcription have been made.

Bakgrund: Bukaortaaneurysm (AAA) har under de senaste tjugo åren blivit allt vanligare både när det gäller förekomst och diagnostisk upptäckt. Oftast är sjukdomen symtomfri och upptäcks ofta först när det rupturerar. AAA behandlas med antingen endovaskulär aortaaneurysm reparation (EVAR), öppen kirurgi av aorta (ÖA), farmakologiskt eller inte alls.Syfte: Syftet var att se hur mortaliteten och komplikationerna ser ut efter EVAR jämfört med ÖA och vilka olika kort- respektive långsiktiga för- och nackdelar som finns med de olika metoderna.Metod: Sökning av artiklar gjordes i databasen PubMed. Totalt valdes 10 artiklar ut som var baserade på 6 olika studier.Resultat: Majoriteten av dödsfallen som skedde inom 30 dagar hos ÖA-patienterna var aneurysmrelaterade och fler än inom EVAR. Efter 2-3 år syntes inte längre någon signifikant skillnad mellan de två patientgrupperna.
