  1. 1. Nurse staffing, care left undone and patient mortality in acute hospitals

    Författare :Jane E Ball; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Failures in the care provided in hospitals may threaten patient safety. Research since the 1980s has established an association between lower registered nurse (RN) staffing levels and higher risk of death in acute hospitals. When RNs have more patients to care for, there is also a greater chance that some nursing care is missed. LÄS MER

  2. 2. Sustainable Manufacturing through Material Efficiency Management

    Författare :Sasha Shahbazi; Magnus Wiktorsson; Peter Ball; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Innovation and Design; innovation och design;

    Sammanfattning : Material efficiency contributes to reduced industrial waste volumes, reduced extraction and consumption of virgin raw materials, increased waste segregation, decreased energy demand, and reduced carbon emissions, thereby generally mitigating the environmental impact of the manufacturing industry. However, the area of material efficiency in manufacturing is under-researched, and related knowledge is limited particularly at individual manufacturing sites and lower levels. LÄS MER

  3. 3. Bimanual movement control : insights from golf ball striking

    Författare :Fredrik Tinmark; Toni Arndt; John Rasmussen; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin Teknik; Medicine Technology;

    Sammanfattning : The aim of this thesis was to gain insight into the control of complex bimanual movements that are both fast and accurate. For this, skilled golf ball striking was used as a model in two experimental studies (I and III). LÄS MER

  4. 4. Properties of oil and refrigerant mixtures : lubrication of ball bearings in refrigeration compressors

    Författare :Roger Tuomas; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Sammanfattning : A refrigeration compressor contains highly loaded mechanical contacts that have to be lubricated. The lubricant used in refrigeration compressors consists of an oil and refrigerant mixture, and the refrigerant concentration can be up to 40 wt%. LÄS MER

  5. 5. Keep it rolling : Straight-line orientation in South African ball-rolling dung beetles

    Författare :Lana Khaldy; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ball-rolling dung beetle; Orientation; Heading direction network; Compass; Weighting; Celestial cues; Sun; Polarised light;

    Sammanfattning : Representing a substantial range and variety in morphological and ecological niche, found on all continents of the globe (except for the Antarctic), the ball-rolling dung beetles provide an excellent model in which to study the heading direction network and the factors by which it is influenced. As soon as a ball-rolling dung beetle has located a fresh dung pile to feed on, it immediately starts shaping a piece of dung into a ball, rolling it away from the dung pat in as straight of a trajectory as the terrain allows.
