  • visual analogue scale vas as a Monitoring Tool for daily changes in asthma symptoms in adolescents a prospective study
    Allergy Asthma & Clinical Immunology, 2017
    Co-Authors: Hyekyun Rhee, Michael Belyea, Jennifer R Mammen
    Abstract:

    Background Success in asthma management hinges on patients’ competency to detect and respond to ever-changing symptom severity. Thus, it is crucial to have reliable, simple, and sustainable methods of symptom Monitoring that can be readily incorporated into daily life. Although visual analogue scale (VAS) has been considered as a simple symptom assessment method, its utility as a daily symptom Monitoring Tool in adolescents is unknown. This study was to determine the concurrent validity of VAS in capturing diurnal changes in symptoms and to examine the relationships between VAS and asthma control and pulmonary function.

  • fluorescence as a potential Monitoring Tool for recycled water systems a review
    Water Research, 2009
    Co-Authors: Rita K Henderson, Kathleen R Murphy, Adam Hambly, Richard M Stuetz, Andy Baker, Stuart J. Khan
    Abstract:

    Abstract A rapid, highly sensitive and selective detector is urgently required to detect contamination events in recycled water systems – for example, cross-connection events in dual reticulation pipes that recycle advanced treated sewage effluent – as existing technologies, including total organic carbon and conductivity Monitoring, cannot always provide the sensitivity required. Fluorescence spectroscopy has been suggested as a potential Monitoring Tool given its high sensitivity and selectivity. A review of recent literature demonstrates that by Monitoring the fluorescence of dissolved organic matter (DOM), the ratios of humic-like (Peak C) and protein-like (Peak T) fluorescence peaks can be used to identify trace sewage contamination in river waters and estuaries, a situation analogous to contamination detection in recycled water systems. Additionally, strong correlations have been shown between Peak T and biochemical oxygen demand (BOD) in rivers, which is indicative of water impacted by microbial activity and therefore of sewage impacted systems. Hence, this review concludes that the sensitive detection of contamination events in recycled water systems may be achieved by Monitoring Peak T and/or Peak C fluorescence. However, in such systems, effluent is treated to a high standard resulting in much lower DOM concentrations and the impact of these advanced treatment processes on Peaks T and C fluorescence is largely unknown and requires investigation. This review has highlighted that further work is also required to determine (a) the stability and distinctiveness of recycled water fluorescence in relation to the treatment processes utilised, (b) the impact of matrix effects, particularly the impact of oxidation, (c) calibration issues for online Monitoring, and (d) the advanced data analytical techniques required, if any, to improve detection of contamination events.

  • an operational Monitoring Tool facilitating the transformation of urban brownfields into sustainable neighborhoods
    Building and Environment, 2018
    Co-Authors: Martine Laprise, Sophie Lufkin, Emmanuel Rey
    Abstract:

    Abstract The regeneration of urban brownfields is a relevant strategy to limit the sprawling of post-industrial European cities. However, the integration of sustainability issues in urban brownfield regeneration projects is not a spontaneous process, remaining in most cases partial or superficial. Achieving the goals of sustainable development requires high global quality objectives, integrated into the project dynamics, and a continuous Monitoring of environmental, social, and economic indicators, adapted to the specificities of brownfields. Following these considerations, an operational Monitoring Tool facilitating the transformation of urban brownfields into sustainable neighborhoods was created. This paper presents and discusses the verification stage of the Tool, divided into two complementary tests: 1) test-applications on three case studies in Belgium, France and Switzerland and 2) interactions with the involved stakeholders. First, we describe the functioning of the Tool. Then, we present the test-applications results, supported by the Val Benoit project in Liege (Belgium) as an example. They are followed by the interactions with the stakeholders that took the form of roundtable discussions. Finally, we discuss the performance of the Tool looking at its potential added-value. It reveals that an adapted operational Monitoring Tool can facilitate sustainability assessment, reporting, decision-making and multidisciplinary collaboration. Globally speaking, the integration of Monitoring practices appears not only feasible, but also realistic and desired.
