This master thesis was conducted during the spring of 2014 at Atlas Copco Rock Drills AB in Örebro. The purpose of the thesis was to develop a simulation model of the rotation system for a hydraulic rock drill. In the future, the model will be used to investigate the phenomena called ?jerky rotation?. In order to validate the simulation model a test bench was designed and tests were made.

Attitudes towards violence were assessed using both implicit (The Single Category Implicit Association Test; Karpinski & Steinman, 2006) and explicit measurements (a Feeling Thermometer). A group of criminals showed more positive explicit and implicit attitudes towards violence than a group of non-criminals. In addition, The Aggression Questionnaire (Buss & Perry, 1992) revealed significant differences in aggression between the groups; criminals' mean scores were higher on all four subscales (physical aggression, verbal aggression, anger and hostility). Furthermore, significant correlations were found between all the measures, including the implicit and explicit attitude measures. The findings support the validity of the SC-IAT as an implicit measure of violent attitudes.

Globaliseringen och den ökade konkurrensen ställer större krav på företagen vilket har medfört att arbetet med logistik har utvecklats från att enbart förknippas med transporter av varor till att idag förknippas med effektiva flöden inom hela försörjningskedjan. Flödena inom försörjningskedjan består av material-, betalnings- och informationsflöden, där det finns en stark koppling mellan alla tre. En väsentlig skillnad mellan de tre flödena är att materialflöde och betalningsflöde representerar kapitalbindning i motsats till informationsflöde som inte hanterar ett direkt ekonomiskt värde. Det bidrar ofta till att informationsflödet förbises i effektiviseringsprocesser. Eftersom ett informationsflöde kan stå för avgörande indirekta värden är det en viktig pusselbit för att försörjningskedjan skall kunna nyttja sina resurser optimalt.

AbstractThis essay discusses the negotiation of the Comprehensive Test Ban Treaty (CTBT) and the process that led up to a signed agreement. The CTBT forbids all nuclear weapon test explosions and all other types of nuclear explosions. The purpose of the study was to distinguish the critical steps of the negotiations that resulted in the success of the CTBT. Based on these insights, my intention was to identify relevant events and actors in the process around the Fissile Material Cut-off Treaty (FMCT), which has been on the nuclear disarmament agenda for over a decade. Furthermore, my ambition was that the examination of the CTBT negotiation would give me some clarity in what the next step would be to get the FMCT back on track.

The project Design analysis and proposals of plastic screw caps in Australia was performed at Högskolan Dalarna incooperation with University of Western Sydney, Australia. The Swedish company Tetra Pak, in Lund, were assigner forthe project that was performed 2006-2007. The commission was to do a survey about the packages for non-carbonateddrinks in Australia. The bottles had to be plastic, able to open in one step and with focus on the caps.The project has result in design analysis and a new proposal of a plastic screw cap for the Australian market. Sixbottles were choosen and they were all testet on 20 consumers each with a Likert-scale test.

Den svenska byggbranschen står i nuläget inför en stor teknisk förändring, införandet av Bygg-informationsmodeller(BIM)/Virtual Design and Construction (VDC) i stor skala. Branschens olika aktörer ser olika vinster med implementeringen som kommer påverka hela byggprocessen, från projektering till förvaltning. Denna studie fokuserar på organisation och process i projekteringsskedet och grundar sig på en fallstudie av Veidekke Entreprenad AB. Företaget har implementerat VDC i delar av organisationen och i nuläget, efter lyckade pilotprojekt, utvidgas satsningen och implementering görs i större skala. Studiens syfte är att kartlägga Veidekkes VDC-mål och strategier, för att därefter studera process och organisation i projekteringsfasen och hur de bör utvecklas för att skapa goda förutsättningar för att VDC-målen ska kunna uppfyllas.

Syftet med föreliggande studie var att undersöka eventuella skillnader mellan barn med cochleaimplantat (CI) och/eller hörapparat (HA) och normalhörande barn i åldrarna fem till sju år avseende fonologiska och kognitiva förmågor. I studien jämfördes resultat från elva till 44 normalhörande barn med åtta till 25 barn med CI/HA från fyra olika studier. Undersökningsmaterialet utgjordes av kortversionen av Stora fonemtestet, fonologiska representationer, TOWRE samt fem deltest ur testbatteriet SIPS. Testresultaten analyserades kvantitativt och för kortversionen av Stora Fonemtestet även kvalitativt. Resultatet visade att barnen med CI/HA generellt presterade lägre än de normalhörande barnen på test av fonologisk förmåga och fonologiskt arbetsminne, men att de låg i nivå med de normalhörande barnen avseende generellt och visuospatialt arbetsminne.

Aim: The aim of the study was to investigate 1RM and what power could be generated in bench-press and half squat concentric at certain percentages of 1RM. Special interest was put to evaluate men (M) and women (K), strength trained (ST) verses non strength trained (EST) in generating absolute power as well as power relative to 1RM.Method: In total 59 subjects mean (± SD) age 24.9 ± 4.1 years divided into four test groups: 20 male non strength trained GIH-students (EST M), 20 female non strength trained GIH-students (EST K), 10 male strength trained - sprinters on national/regional level (ST M), 10 female strength trained - sprinters (ST K) on national/regional level. They did two tests on 1RM and power in events of concentric bench-press and half squat in a Smith machine. In the first test session 3 ? 5 lifts were made to measure 1RM in each event.

New tools for the assessment of aphasia are important for bothclinical work and research. To see how they relate to already existing testscan increase their usefulness. Western Aphasia Battery ? Revised was translatedto Swedish and compared with the Swedish aphasia test A-ning, partlyto compare content and partly to see how sixteen people aged between 22and 92 with aphasia performed on the tests. The subtests did not correspondcompletely and the type of items included varied a lot.

This essay includes the planning and designing of a house as well as writing a rapport about howto increase fire safety in small buildings.More than 6000 homes burn in Sweden every year (Brandskyddsföreningen, 2012c). Thedevastation and the costs are usually very high. This report examines possible measures to reduceboth personal injuries and economic losses resulting from house fires in small buildings.Swedishbuilding regulationsplay a major role when it comes to constructional fire safety. However therequirements inSwedish building regulations are very low for small buildings and this is anargument for raising the requirements.The report shows and describes possible methods to build safer with regards to fire in terms ofmaterials and different building structures. Major focus has been on fire cells but other solutionsare also examined and described.

The purpose of this Masters thesis is to examine how young womens sexuality is described in Swedish youth novels. The analysis is based upon eight books of which four were published during the period from 1970 to 1975 and four books were published during 2000 to 2005. The theoretical framework is based on a gender theoretical perspective where Yvonne Hirdmans theories about a gender system and Ylva Elwin-Nowaks and Heléne Thomssons ideas about gender construction are crucial. Also Anthony Giddens theories about sexuality in the late modern society are used, where the plastic sexuality and the pure relationship are central ideas. The method is based upon textual analysis, and a model of analysis is constructed with its basis in the theoretical attempt.

Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.

Syftet med denna studie var att undersöka vad stress innebär, hur det upplevs och orsakas inom Räddningstjänsten, samt hur det kan förebyggas. Enkäten gjordes utifrån ett kvantitativt perspektiv och skickades till larmoperatörer och brandmän på Räddningstjänsten. Enkäten besvarades av totalt 33 respondenter. Deltagarnas ålder togs inte i beaktning, enbart antalet år av yrkeserfarenhet. Datan analyserades I SPSS, med hjälp av ett Chi-tvåtest och ett Pearsons's r-test.
