1. Nurse staffing, care left undone and patient mortality in acute hospitals
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. Sustainable Manufacturing through Material Efficiency Management
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. Bimanual movement control : insights from golf ball striking
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. Properties of oil and refrigerant mixtures : lubrication of ball bearings in refrigeration compressors
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. Keep it rolling : Straight-line orientation in South African ball-rolling dung beetles
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.
