  1. 1. Den osynliga misshandeln : psykisk misshandel av barn och möjliga konsekvenser för vuxenlivet.

    Uppsats för yrkesexamina på grundnivå, Högskolan Väst/Avdelningen för omvårdnad - grundnivå

    Författare :Emma Hulthén; Anna Norstedt; [2019]
    Nyckelord :childhood; emotional abuse; mental health; nursing; outcomes;

    Sammanfattning : Background: Childhood emotional abuse can lead to mental illness. Research about emotional abuse is limited and therefore complicates the work of the nurse, since understanding of what emotional abuse means is of importance. LÄS MER

  3. 2. Modelling the influence of porosity on fatigue strength of sintered steels

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Emily Hall; [2019]
    Nyckelord :Fatigue; Powder metallurgy; PM; sintered steels; fracture mechanics; porosity; metal powders; fatigue strength; fatigue limit; utmattning; pulvermetallurgi; metallpulver; utmattningsgräns; brottmekanik; porositet; sintring;

    Sammanfattning : The pores in pressed and sintered components constitute weak points in the material since the stress concentration is larger than the nominal stress there. Therefore, fatigue cracks initiate at the pores. Specifically, it can be assumed that the fatigue cracks initiate at the largest pore in the stressed volume. LÄS MER

  4. 3. Multitaper analysis of HRV power and its stress-related correlation to respiration frequency

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Zite He; [2018]
    Nyckelord :Multitaper multiple windows ; Heart rate variability HRV ; Spectrum anal- ysis; Integrated pulse frequency modulation IPFM ; High frequency band HF ; Thomson multitaper TH MW ; Peak-matched multitaper PM MW ; Correlation.; Mathematics and Statistics;

    Sammanfattning : In this Master thesis, different multitaper methods are implemented to estimate the spectra of respiratory signals and HRV data, and further to estimate the correlation between the respiratory center frequency and the narrow-banded high frequency band of HRV power. The methods are applied first on ARMA-process data, then on the integrated pulse frequency modulation (IPFM) data simulations, where the evaluation is performed by calculating the bias and standard deviation of the narrow-banded HRV power and its correlation with respiratory frequency.

  5. 4. Property Optimization of PM-gearing

    Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Marcus Söderberg Jansson; Oskar Lundkvist; [2017]
    Nyckelord :Gear; Powder Metallurgy; Property optimization; Egenskapsoptimering; Kugghjul; Pulvermetallurgi;

    Sammanfattning : The purpose of this bachelor thesis is to design and optimize a powder metal gear through FEM-analyzes. The moment of inertia and weight of the gear shall be reduced at the same time as the demands on tension and bending stiffness are met. LÄS MER

  7. 5. Anestesisjuksköterskors erfarenheter av vård av patienter med missbruksproblem : En intervjustudie

    Magister-uppsats, Umeå universitet/Institutionen för omvårdnad

    Författare :Agneta af Bjerkén; Mia Åslund; [2017]
    Nyckelord :Anaesthetic nurse; Misuse; Strategies; Experiences; Anestesisjuksköterska; Missbruk; Strategier; Erfarenheter;

    Sammanfattning : Syftet med studien var att beskriva anestesisjuksköterskors strategier kring omvårdnaden av patienter med missbruksproblem inom anestesiologisk omvårdnad.Bakgrund Anestesisjuksköterskan möter dagligen patienter med olika bakgrund, förutsättningar och behov. LÄS MER
