En livsviktig utveckling : en reviewstudie om hjärt- lungräddning (HLR)
AimThe aim of this study was to find out how the research that has changed CPR training developed from a historical perspective. The question at issue was: When the recommendations for chest compressions/ventilation, defibrillator and education have been changed, what kind of research led to the development?MethodTo fulfill the aim of this study we chose a review process. First we read the international guidelines for cardiopulmonary resuscitation (CPR) published by the American Heart Association (AHA), from year 1980 until year 2010. Secondly we chose the most important changes that had been made within the issues we had selected, then we examined the research that had supported these issues.
Svartrost, Puccinia graminis f. sp. avenae, epidemiologi och bekämpningsstrategier i Mälardalen
Stem rust, Puccinia graminis, has caused enormous yield losses throughout history which have had significant consequences for oat and wheat production. Today in Sweden stem rust is only reported from rye, oats and wild grasses. Stem rust infections in wheat have become unusual due to the general use of resistant wheat varieties and also due to the eradication of barberry, Berberis vulgaris, the alternate host for P. graminis. According to international sources, new races of P.

Kraftspelsanalys av transportstag : Prefabricerade väggelement i betong
A titania-supported nickel catalyst was prepared and tested in methanation in order to evaluate its catalytic properties (activity, selectivity and specially, activity loss), and compare it with an alumina-supported nickel catalyst.The titania-supported catalyst did not only show higher stability than alumina, but also presented a different cause of deactivation, carbon formation. In addition, a kinetic model was obtained for the titania-supported catalyst, and a study of the effect of different operating conditions (temperature, composition and partial pressures of synthesis gas and water) on the deactivation rate and carbon formation of this catalyst was performed.
Lyftkraftsberäkning för vingprofiler: Virvelpanelmetoden
The problem presented in this report is that of finding a method to calculate the lift force from a single-element airfoil of arbitrary shape. A number of restrictions are used in order to simplify calculations while retaining reasonable accuracy. The problem is solved for the two-dimensional case only and no finite-wing effects are taken into account. Furthermore, inviscid and incompressible flow is assumed. The method used to solve the problem is the vortex panel method, with vortex singularities distributed over simplified airfoil geometry.
Analys och modellering av ljusbåglängdsregleringen i pulsad MIG/MAG-svetsning
This master thesis deals with problems in the arc length control in Pulsed MIG/MAG Welding. The main problem is that it is not possible to measure the arc length. In the present solution the voltage over both the electrode and the arc represents the arc length. To improve the arc length control a model of the electrode melting has been built. One output from the model is the voltage over the electrode and with this voltage together with the measured voltage it is possible to calculate the voltage over just the arc.
Skoldemokrati : En kvalitativ intervjustudie som undersöker elevrådet och elevkåren som demokratiska forum för gymnasieelever i Stockholm.
The main objective in this study is to examine the pupil?s possibility to affect the upper secondary schools in Stockholm, Sweden. I was once active in the pupil?s council and experienced some hardships, feeling a great dissatisfaction among teachers and principals against pupil?s suggestions and chances to affect their school environment. Thus I wanted to do a contemporary study of where schools in Stockholm stand today within this issue.
LCC-kalkyler i byggbranschen : förutsättningar och tolkning av resultat
Background:Life-cycle costing (LCC) is an investment calculation that takes intoaccount operating costs throughout the investee lifecycle. LCC calculations are mainly usedto evaluate investments that have no revenue side. Attempts to apply the LCC calculations forbuilding-related investments have occurred since the 1980s. Despite the advantages ofusing LCC calculations, use has not passed through in full. The main obstacles have beenidentified as a lack of relevant input data, and insufficient experience of workingwith LCC calculations.
Vindkraft eller kärnkraft - En jämförelse
The scope of this project is to make a comparison of costs associated with wind and nuclear power in order to decide which one of these is the most suitable in the case of an increased demand for electricity. It is also investigated if there are other factors that can influence the choice of energy source.An average cost is calculated in terms of kronor per kilowatt-hour (SEK/kWh) using cost of investment, operation & maintenance and taxes & subsidies. Total investment cost is recalculated to production cost using the annuity method at three different interest rates (6%, 9% and 12%).The comparison is made between three cases of wind power and two cases of nuclear power. For wind power there are two ocean-based (300MW and 100MW installed capacity, respectively) and one land-based (60MW) wind farm. For nuclear power there is one EPR-reactor (1600MW) and one AP1000-reactor (1100MW).
Utveckling och utförande av frekvensstudie vid Rapid Granulator AB
The object of this examination project is to produce a method of work sampling at Rapid Granulator AB. The aim is to perform the method at the company and evaluate if it is executable. The study is delimited to the basic construction of the 45-series in the assembly hall.Preparations to produce the method of the work sampling resulted in definitions of activities, a form and a product tree. Several days were spent studying the assembling to learn and understand the entirety.The work sampling result showed a large amount of no value adding time that was used in the assembling. Some of the activities could be reduced and we observed some problems during the assembly process.
Fjortisgrubbel och tonårskärlek : ? en genusstudie av två svenska ungdomsfilmer gjorda med 35 års mellanrum
AbstractHeadline: Young trouble and teenage love (Fjortisgrubbel och tonårskärlek)Number of pages: 37Author: Annika IlmoniTutor: Amelie HössjerCourse: Media and communication CPeriod: Autumn 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/aim: The purpose of the work was to produce a comparing study of two Swedish teenage films from different periods of time, 1970 and 2005. An analysis was to be made of how love between teenagers as well as the heterosexual relationship in general was depicted in each of the films and further investigate the gender construction in both films.Material/method: With the intention of narrowing down the complexity and make the evaluation more lucid 5 scenes from each film were used for comparison, these were chosen through the Anglo Saxon dramaturgy. To make the scenes more comparable 4 factors were used for analysis in each scene, these were: clothes, recreational activities, behaviour and environment. Beside the above given factors the heterosexual relationship were analysed and compared in each of the scenes through the theory of dominance in dialogue.Main results: The gender construction occurs obliviously in the older film from 1970 while taking place in a more conscious way in the film from 2005. Further on the heterosexual relationship is perpetually depicted in the 70?s film with a submissive girl and predominant boy, the same dominance is easily seen in the more recent film but with a higher rate of equality as the girl is portrayed as the dominant character in almost half of all scenes.
Intrerssenter, identitetskriser och ideologi: Formandet av stadens varumärke
The purpose of this paper is to evaluate the work situation for temporary workers within the field of journalism. During the past decade, influential external forces such as commercialization, new technologies and increased competition have brought great changes within the industry. As a result, employers value flexibility of manpower, not least to reduce cost, where the flexible employee is usually leased by the media company from a manpower company. Today it is a normal practice with manpower companies and this way of hourly paid form of employment. Although the temporary worker can sometimes benefit from this kind of employment, there are also significant setbacks like job insecurity.
Möjlighet att tillgodose barns behov vid långvarigt uppbärande av försörjningsstöd : En kvantitativ studie genomförd i Enköpings kommun under hösten 2012
The purpose of this thesis is to examine whether parents that obtain long-term maintenance support in Enköping, consider the support as adequate when trying to meet their children's basic needs. The thesis also intends to investigate whether parents experience that their children, because they receive income support, have been socially excluded or stigmatized in their daily lives because of the family?s maintenance support. Further, the thesis aims to examine if there are any discrepancies in the above mentioned issue in relation to how long the parents have received maintenance support. Theoretical starting points used in this thesis mainly consist of the child perspective, social exclusion and the stigmatization theory.
Deltack, Blanket Study
There are two objectives of this study.The first one was to study the new instrument Deltack fromPrufbau, and with the new knowledge, study the interaction between blanket and paper.Deltack is a new instrument to measure the ink splitting force. Blankets from an earlier study doneby GATF have been montered on 12 different Deltack print forms and those have together with Deltackbeen the base for this project.This study together with information from GATF?s study shows that some of the blankets have ahigher capability to adsorb ink. Those blankets generate a sharper shape on the force curve, they havea lower dot gain, but they print not as good solid..
Att vara ung och leva med diagnosen ADHD. En kvalitativ intervjustudie med fokus på sociala och existentiella aspekter
Today many children and youths are allocated to ?The Swedish Authority of Child and Youth Psychiatry (BUP) for the sake of being investigated by means of a neuropsychiatric inquire and many of which are assigned the diagnosis ADHD. During recent years ?The Swedish National Board of Health and Welfare? has declared, in it?s annual account of the current psychiatric state of Swedish Children and Youths, that the healthcare provided for those with neuropsychiatric diagnoses ? such as Asperger syndrome and ADHD, has increased.ADHD is short for Attention deficit hyperactivity disorder, which implies neuropsychiatric impediments i.e. hyper activity, inadvertence and an inability to control impulses.The aim of the Study is to describe and analyze how youth, in the age range of sixteen to eighteen years of age, diagnosed with ADHD define themselves, their daily life, their social state, their next to kin relationships and, finally, their concept of their future.The Study is qualitative.
