Characterization of the Heat Extraction Capability of a Compliant, Sliding, Thermal Interface for Use in a High Temperature, Vacuum, Microgravity Furnace

A compliant, thermal interface material is tested to evaluate its thermal behavior at elevated temperatures, in vacuum conditions, and under varying levels of compression. Preliminary results indicate that the thermal performance of this polymer fiber-based, felt-like material is sufficient to meet thermal extraction requirements for the Quench Module Insert, a Bridgman furnace for microgravity material science investigation. This paper discusses testing and modeling approaches employed, gives of a status of characterization activities and provides preliminary test results

Responsive Web Site Development at the Library, Institute of Technology Tallaght: A Case Study

This case study reviews the responsive Web design project undertaken by the Library, Technological University Dublin, with Granite Digital, including the preparatory literature review, the design process, task allocation, and the technologies leveraged to deliver the final design. The library is a small academic library with limited resources, and the project took place during a particularly challenging period in Ireland. The different types of testing the site underwent before launch are discussed, including testing of the design itself across browsers, accessibility testing using free online resources, testing the responsive design using free online resources, and physical device testing. The article outlines how feedback was gathered and addressed, and discusses plans for future upkeep and development. Finally, the article concludes that it is possible for a small academic library to successfully deliver a high quality library Web site using responsive design. “This is an Accepted Manuscript of an article published by Taylor & Francis in JOURNAL OF WEB LIBRARIANSHIP on 17th Cotober, 2016, available online: http://www.tandfonline.com/doi/full/10.1080/19322909.2016.122914

Registered nurses` lived experience of advocacy within a critical care nuit: a phenomenological study

Anecdotally, it has often been expressed by registered nurses (RNs) working within critical care environments that they are patient advocates. However, to date, little systematic research has been undertaken to validate this assertion. Thus this project, which explored the lived experience of RNs working within a critical care unit in a country area of Australia, was conceived.The five participants of this study were all Division 1 RNs possessing a critical care certificate and a minimum of 4 years\u27 nursing experience. Through their participation in an in-depth audiotaped interview they revealed a wealth of experiences and ideas about their involvement as patient advocates. The results of this research indicate that the phenomenon of nurse advocacy is a multi-faceted process and embraces many kinds of activities that nurses engage in on behalf of their clients.The findings of this study indicate that some of the participants\u27 experiences are congruent with elements of advocacy contained within the nursing literature and statements of professional nursing bodies. However, there are some findings in this study that are not consistent with available literature. For instance, these participants markedly reject the notion that advocacy is an inappropriate concept for nurses, despite suggestions in the literature that this is an inappropriate role. Instead they wholeheartedly embrace this role, asserting it as central to their practice. Further, although the literature identifies potential controversies regarding enactment of the role of advocacy, the participants of this study are silent on these matters. It is not known what this silence implies and, in light of the study findings, it is recommended that nursing organisations, theorists and clinicians consider whether it is worthwhile to more clearly confirm the nature and role of advocacy within Australian nursing.<br /

Mechanical Ventilation Management during Extracorporeal Membrane Oxygenation for Acute Respiratory Distress Syndrome. An International Multicenter Prospective Cohort

Rationale: Current practices regarding mechanical ventilation in patients treated with extracorporeal membrane oxygenation (ECMO) for acute respiratory distress syndrome are unknown.Objectives: To report current practices regarding mechanical ventilation in patients treated with ECMO for severe acute respiratory distress syndrome (ARDS) and their association with 6-month outcomes.Methods: This was an international, multicenter, prospective cohort study of patients undergoing ECMO for ARDS during a 1-year period in 23 international ICUs.Measurements and Main Results: We collected demographics, daily pre- and per-ECMO mechanical ventilation settings and use of adjunctive therapies, ICU, and 6-month outcome data for 350 patients (mean ± SD pre-ECMO PaO2/FiO2 71 ± 34 mm Hg). Pre-ECMO use of prone positioning and neuromuscular blockers were 26% and 62%, respectively. Vt (6.4 ± 2.0 vs. 3.7 ± 2.0 ml/kg), plateau pressure (32 ± 7 vs. 24 ± 7 cm H2O), driving pressure (20 ± 7 vs. 14 ± 4 cm H2O), respiratory rate (26 ± 8 vs. 14 ± 6 breaths/min), and mechanical power (26.1 ± 12.7 vs. 6.6 ± 4.8 J/min) were markedly reduced after ECMO initiation. Six-month survival was 61%. No association was found between ventilator settings during the first 2 days of ECMO and survival in multivariable analysis. A time-varying Cox model retained older age, higher fluid balance, higher lactate, and more need for renal-replacement therapy along the ECMO course as being independently associated with 6-month mortality. A higher Vt and lower driving pressure (likely markers of static compliance improvement) across the ECMO course were also associated with better outcomes.Conclusions: Ultraprotective lung ventilation on ECMO was largely adopted across medium- to high-case volume ECMO centers. In contrast with previous observations, mechanical ventilation settings during ECMO did not impact patients' prognosis in this context
