  1. 1. Altering the birthing room - The influence on birth outcomes and provision of care

    Författare :Lisa Goldkuhl; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Childbirth; Birthing room; Birth environment design; Childbirth experience; Salutogenesis; Atmosphere; Complex interventions; Implementation; Randomised controlled trial; Ethnography;

    Sammanfattning : Giving birth is a complex physiological process deeply influenced by psychological and social elements. A prerequisite for optimising this physiological process is to be in an environment that feels safe and protective. LÄS MER

  3. 2. Critical Aspects of High Performance Manufacturing of Structural Sintered Steel

    Författare :Sepehr Hatami; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tool Steels; Modelling; Controlled Atmosphere; Wear Mechanisms; Sintering; Pressing Dies; Chromium Alloyed Steel;

    Sammanfattning : Steel is the dominant material for the production of structural parts. By means of powder metallurgy (PM) processing, manufacturers have been able to manufacture steel parts with appreciable dimensional accuracy and proper mechanical properties. LÄS MER

  4. 3. Semipermeable membrane devices as integrative tools for monitoring nonpolar aromatic compounds in air

    Författare :Hanna Söderström; Mats Tysklind; Per-Anders Bergqvist; Jochen F. Muller; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; air pollution; alkyl-PAHs; atmosphere; bioavailability; boundary layer; diffusive sampling; emissions; integrative; membrane; monitoring; nitro-PAHs; PAHs; particles; passive samplers; PCBs; plants; PRCs; release rate; sampler design; sources; SPMDs; traffic; uptake rate; wind effect; wood burning; Miljökemi; Environmental chemistry; Miljökemi;

    Sammanfattning : Air pollutants pose a high risk for humans, and the environment, and this pollution is one of the major environmental problems facing modern society. Active air sampling is the technique that has been traditionally used to monitor nonpolar aromatic air pollutants. LÄS MER

  5. 4. Alcohol Intervention Studies in University Students. Randomised Controlled Trials of Responsible Beverage Service and High Risk Drinking

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; University; Psykiatri; psychosomatics; clinical psychology; Psychiatry; Medicin människa och djur ; Medicine human and vertebrates ; Breath alcohol concentration.; AUDIT.; Trajectory.; Randomized Controlled Trial.; Normative feedback.; Alcohol prevention; klinisk psykologi; Server intervention.; College; psykosomatik;

    Sammanfattning : The aim was to study implementation and efficacy of two intervention techniques for risky alcohol consumption in university students. One technique was the Responsible Beverage Service Programme modified for use in students pubs. LÄS MER

  7. 5. The mutual interaction between the time-mean atmospheric circulation and continental-scale ice sheets

    Författare :Johan Liakka; Johan Nilsson; Johan Kleman; Gerard Roe; Stockholms universitet; []
