PATIENTS' TRANSCULTURAL NEEDS AND CARERS' ETHICAL RESPONSES
No full textMany Turkish people migrated to Germany between 1955 and 1975. This study was carried out in Gottingen, Germany. Fifty Turkish people (described as patients) were asked about the care they had received from German health care personnel, and 50 German nurses and 50 German physiotherapists were questioned about care they had given to Turkish patients. Significant findings were the needs of the Turkish patients for good communication, physical contact and understanding of their culture-based expressions of illness. The German nurses and physiotherapists expressed the need for language barriers to be minimized and for education in the specific culture of Turkish patients. Our findings are discussed from an ethical viewpoint. The International Council of Nurses' code of ethics is used to guide the ethical debate about the findings within the context of transcultural and multicultural care. Suggestions for better transcultural health care paradigms are made for relating to patients from different cultures when patients and care providers have little understanding of each other's needs and expectations.
Hot-thermistor spirometry for the artificial ventilation of infants
No full textBibliography: leaves 230-245.This thesis describes equipment and techniques which were developed for use in monitoring mechanical aspects of artificial ventilation and optimising ventilation procedures. A strong emphasis is placed on the clinical applicability of the techniques and clinical applications are discussed. A new temperature-compensated hot-thermistor anemometer/spirometer was developed because the wide variety of spirometers described previously for-measuring respiratory volumes •and volume flow rates were unsatisfactory for routine use in monitoring infant ventilation. The principles of hot-thermistor spirometry were investigated both theoretically and experimental.ly to develop new temperature-compensation techniques and to predict the effect of gas composition changes on spirometer celebration. New electronic circuits were developed which greatly simplify the construction of temperature-compensated hot- thermistor anemometers and extend the dynamic range off low rates that can be measured
Experiments with micro-machined multi-array hot-film probe towards field experiments woth sub-Kolmogorov resolution
No full textThis is a report on implementation of the next stage of a project, motivated by the discovery of far more important role, played by the sub-Kolmogorov scales in high Reynolds number turbulence than commonly believed. The main results and issues that prompted the present work are in [1] – [3] and references therein. At this stage we report on the first successful experiments with a unique micro-machined hot-film multi-array probe. This includes design, assembly, implementation and testing of such probe in laboratory conditions. The probe is enabling to access, along with all three components of turbulent velocity fluctuations, also all nine components of the spatial velocity gradients tensor, including the option of obtaining the stream-wise velocity derivatives without employing the Taylor hypothesis, as well as velocity temporal derivatives. The key feature of the micro-machined multi-array probe (typically five arrays), with each array consisting of four micro-machined hot-film sensors, is that it is six times smaller than the conventional multi-array probe, based on arrays with four hot wires [4] – [5], used in the atmospheric surface layer at Taylor micro-scale Reynolds number up to Reλ ≈ 10⁴. This part of work relates to Reynolds numbers Reλ < 500 and employs several laboratory flows
Extending hot authentication: Imagining fantasy space
No full textFantasy fiction inspires many tourists to seek out and explore sites associated with the originality and inspiration of the production of texts. This paper investigates how both tourists and tourism providers infuse their authentication of urban legends about the inspiration for Harry Potter locations with imagination and (dis)belief. The study extends the theory of hot authentication and assesses author inspiration as an object of tourist desire. Data analysis includes TripAdvisor reviews of the Shambles in York and semi-structured interviews with fantasy tourism providers. We identify four categories of belief in urban legends: heightened belief, uncertainty, disbelief, and the suspension of disbelief. Our findings demonstrate how hot authentication involves off-centred universe-building which transforms historic streets and simulacra into magical loci
Effect of chemical composition on hot cracking susceptibility (HCS) using various hot cracking criteria
No full textThe paper aims to evaluate the effect of chemical composition on the Hot Cracking Susceptibility (HCS) using mechanical and non-mechanical hot cracking criteria during solidification. The criteria were SKK as a mechanical criterion. Feurer, Clyne Davis, and Katgerman as non-mechanical criteria. The criteria were implemented at various parameters to evaluate their abilities in the hot cracking susceptibility (HCS) prediction at varied chemical composition. In this study, The Mg content was varied in Al9Zn (1, 1.5, 2, 2.5 %wt.) Mg2Cu alloys and Cu content in Al9Zn2Mg (1, 1.5, 2, 2.5 %wt.) Cu alloys. The validation of the result is also conducted by comparing with the experimental data. Based on Feurer criterion, The hot cracking initiates at lower temperature and at higher critical rate of feeding and shrinkage with Cu content, and the hot cracking initiates at higher temperature with Mg content, and it initiates at higher critical rate of feeding and shrinkage from 1 up to 1.5 of Mg, and the critical rate of feeding and shrinkage remains constant from 1.5 up to 2.5 of Mg. Based on Clyne & Davies, the HCS decreases with Cu content from 1 up to 2 of Cu, and it increases from 2 up to 2.5 of Cu. The HCS decreases with Mg content from 1 up to 2 of Mg, and it remains constant from 2 up to 2.5 of Mg. Based on Katgerman criterion, the HCS decreases with Cu content from 1 up to 1.5 of Cu, it increases from 1.5 up to 2 of Cu, and it decreases from 2 up to 2.5 of Cu. The HCS decreases sequentially with Mg content. Based on SKK criterion, the HCS curves shift to the right with Cu content which means that the hot cracking initiates at lower temperature, and the HCS curves shift to the left with Mg content which means that the hot cracking initiates at higher temperature with Mg content. The Feurer, Clyne & Davies, and some specific range for SKK criteria are in agreement for the effect of Cu content on HCS of alloys, and Katgerman and some specific range for Clyne&Davies criteria are in agreement for the effect of Mg content on HCS of alloys.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Team Joris Di
Recent advances in hot tearing during casting of aluminium alloys
No full textHot tearing is one of the most severe and irreversible casting defects for many metallic materials. In 2004, Eskin et al. published a review paper in which the development of hot tearing of aluminium alloys was evaluated (Eskin and Suyitno, 2004). Sixteen years have passed and this domain has undergone considerable development. Nevertheless, an updated systematic description of this field has not been presented. Therefore, this article presents the latest research status of the hot tearing during the casting of aluminium alloys. The first part explains the hot tearing phenomenon and its occurrence mechanism. The second part presents a detailed description and analysis of the characterisation methods of the mushy zone mechanical properties and hot tearing susceptibility. The third part presents considerable data pertaining to the mushy zone behaviour, including those of the linear contraction and load behaviour during solidification, semi-solid strength and ductility, and characteristic points related to hot tearing. The fourth part examines the effect of the composition and casting process parameters on the hot tearing susceptibility of aluminium alloys. The fifth part describes the hot tearing simulations and the associated criteria and mechanisms. Finally, recommendations for the further development of hot tearing research are presented.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Team Kevin Ross
