El Niño Southern Oscillation och dess atmosfäriska fjärrpåverkan.

This paper is a literature study aiming to describe scientists newest theories andknowledge concerning the El Niño and Southern Oscillation. Firstly I have described the?normal? conditions with rising and sinking air in Hadley- and Walker-cells in theequatorial Pacific and from there moved on to explaining the reversed circulation patternsand higher sea surface temperatures (SST) leading to rising air and anomalousprecipitation in eastern Pacific constituting the El Niño phenomenon. My outermostinterest regarding El Niño has been the associated teleconnections, especially in nontropicalareas. I have described the El Niño effect on the Indian summer monsoon, ontropical cyclones and on storms and precipitation on higher latitudes.

V?GEN IN I EN KRIMINELL LIVSSTIL En kvalitativ intervjustudie om f?re detta kriminellas gestaltningar av v?gen in i kriminalitet

The aim of this study is to gain an understanding of former criminals' own experience of their entry into criminality and to identify and analyze the factors they use to explain their path into criminality. To study this area, a qualitative method has been applied with five semi-structured interviews of ex-criminals from an organization that works to help and support people who have previously been involved in crime by offering employment, education, and rehabilitation in order to be further integrated into society again. To analyze the respondents' stories about their way into criminality, the theory of social bond by Hirschi has been applied and contribute with insights in later criminal acts as well as the theory has been problematized to some extent. Today, there is a lot of research on different aspects that can explain the way into criminality in different aspects, on the other hand, research has largely been measured with a quantitative approach with statistics and self-reported data. This study therefore intends to apply a qualitative approach, where ex-criminals themselves describe their path into criminality.

Är vittnen som lämnar konsekventa upplysningar mer tillförlitliga?

I den juridiska litteraturen antas det ofta att vittnesuppgifter som är inkonsekventa också är mindre korrekta (Brewer, Potter, Fisher, Bond och Luszcz, 1999). Om det verkligen förhåller sig så har dock inte undersökts empiriskt i någon nämnvärd utsträckning. Tidigare studier har visat på en svag positiv korrelation mellan korrekthet och konsekvens. En reflexion över statistiska samband leder dock till slutsatsen att hittills hittade korrelationer kan vara artefakter, orsakade av hur variablerna definierats. I denna studie undersöktes om det fanns ett samband mellan vittnens grad av korrekthet och deras grad av konsekvens.

Optimering av betong med Byggcement (CEM II) till håldäcksproduktion

This thesis has been developed inassociation with Strängbetong AB, Sweden.A few years backCementa AB introduced a new type of cement on the Swedish market: Byggcement,which is a Portland Limestone Cement. This type of cement is better for theenvironment and cheaper than Rapid Hardening Cement which is used today at SträngbetongAB.Strängbetong AB isvery interested in a change of cement in the factory and wants to know what ittakes to make a transition from Rapid Hardening Cement to Byggcement.This final projectaims at investigating how the workability and strength development are affectedby a transition from the existing cement to Byggcement and how we can change theproperties of the concrete by adding different types of superplasticizers. Laboratory and factoryexperiments were made, to investigate the transition..

Sahlgrenska Academy at University of Gothenburg Department of Internal Medicine and Clinical NutritionAbstractTitle: Can probiotics prevent atopic dermatitis in children with high risk?Author: Laura Pienihäkkinen and Max OlinSupervisor: Heléne Bertéus ForslundExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 22, 2012Background Allergic disease is today common, this including atopic dermatitis, which is the most common inflammatory skin disease in the world. Heredity has been shown to play a major role in the development of this disease. It is therefore of high interest for both the individual and society to find effective methods for preventing atopic dermatitis in individuals with high risk profile. Probiotics are beneficial for the bacterial profile in the intestine and it is therefore of interest to study if they through their anti-inflammatory effect could prevent atopic dermatitis.Objective The aim was to study whether administration of probiotics to the mother and the child (directly or via breast milk) could prevent atopic dermatitis in children with high risk profile (at least one first degree relative with a diagnosed allergic disease).Search strategy A systematic literature search was done in databases PubMed and Scopus with search terms maternal, prenatal, probiotics, allergy, atopic dermatitis, prevention, and children.Selection criteria Randomized, controlled human studies and original articles in English were included.

Att stanna : En kvalitativ studie om kvinnor med tidigare erfarenheter av våld i nära relationer

Den här studien undersöker kvinnor utsatta för våld i heterosexuella parförhållanden med syftet att undersöka vad som kan påverka att en del kvinnor under lång tid stannar i destruktiva och våldsamma relationer. Den teoretiska referensramen hämtas från ett strukturellt/kulturellt perspektiv i teorin om våldets normaliseringsprocess samt från ett socialpsykologiskt perspektiv genom teorin om det traumatiska bandet. För att uppnå studiens syfte har en kvalitativ metod använts i form av intervjuer. Fem kvinnor med tidigare erfarenhet av våld i nära relationer har intervjuats. Genom en tematisk analysmetod har intervjumaterialet sedan analyserats.

Konstruktion av specialmaskin för orientering och positionering av nyckelämnen

The thesis in product development ? mechanical design includes 15 credits and was carried out during the spring of 2014 at Semcon in Eskilstuna. The task is to construct a special machine for positioning and orientation of a key blank found in six different shapes, the construction is a part of a larger machine for encoding the key blank where a pick- and-place device or robot pick up the key blank and deliver it further in the process. The entire construction is designed for ASSA OEM Gothenburg.In order to accomplish the project the first step was to analyze the existing solutions to similar problems on the market in a current situation analysis to create an understanding of the problem. This was followed by a flow analysis and a functional analysis to get a deeper understanding of the problem and structuring the machine's process flow and its features.

Intuition som ett redskap för sjuksköterskan i vården. En litteraturstudie.

The purposes of this literature review were to study how nurses use intuition in health care, how these experiences are described by nurses and if you as a nurse can learn how to use your intuition. We also want to make nurses attentive of and give them the courage to use their intuition. The study is addressed to both nurs-ing students and practicing nurses. The method is a literature review based on nine scientific articles. The results implicate that nurses use their intuition to know how to do something, when additional measures needs to be done and which measures they are.

Hållfasthetsegenskaper i gjutjärn : tensile properties of cast iron

In the last few years people have become more and more aware of how humanity is affecting the climate. In the direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's truck engines.In order to achieve these requirements it?s necessary to increase the combustion pressure in the engine. This requires higher tensile properties and high thermal conductivity of the engine material. The department of Component Technology at the University of Jönköping in collaboration with Volvo Powertrain AB, Scania CV AB and DAROS Piston Rings AB has been commissioned to develop this material and to find knowledge of material properties used in truck engines and piston rings used for marine applications.The purpose with this work is to analyze the tensile properties of a series of cast iron, cast under different metallurgical conditions.Four different series of cast irons have been analyzed from four points of view, carbon concentration, nodularity, amount inoculation and cooling rate.After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a.
