Effectiveness of a visual noise warning system on noise levels in a surgical ICU: A quality improvement programme
(Lippincott Williams and Wilkins, 2019)
BACKGROUNDThe effects of noise are harmful to patients in the ICU environment, and the latter are particularly noisy places. High noise levels seem to be a factor in sleep disturbance, which can, in turn, result in increased ...
Rethinking professional autonomy: Autonomy to develop and to publish news in Mexico and Colombia
(SAGE Publications Ltd, 2017)
Professional autonomy has usually been defined in terms of journalists' perceptions of their control over their work vis-à-vis organizational supervisors. Using surveys of journalists in Colombia and Mexico, we identify ...
Exact galactic disk-haloes model in Einstein-Maxwell gravity
(World Scientific Publishing Co. Pte. Ltd., 2018)
An exact model in Einstein-Maxwell gravity describing a magnetized galactic disk-halo system is presented. The description of properties of the stationary metric and its source are discussed. All the expressions are presented ...
Mitochondrial DNA analysis suggests a chibchan migration into Colombia
(Pontificia Universidad Javeriana, 2015)
The characterization of mitochondrial DNA (mtDNA) allows the establishment of genetic structures and phylogenetic relationships in human populations, tracing lineages far back in time. We analysed samples of mtDNA from ...
The emergence of cognitive short-term planning: Performance of preschoolers in a problem-solving task
(Universidad Catolica de Colombia, 2015)
The aim of this study is to identify patterns of the cognitive planning process of young children emerging in the context of a problem solving task. Using a complex dynamic systems approach, this paper depicts the main ...
The dynamic model of a four control moment gyroscope system
(Universidad Nacional de Colombia, 2014)
The dynamic model of a Four Control Moment Gyroscope (4-CMG) is traditionally obtained after computing the derivative of the angular momentum equation. Although this approach leads to a simple dynamic model, new models ...
