Air Quality Modelling For Ireland, Aoife Donnelly, Bruce Misstear, Brian Broderick
Air Quality Modelling For Ireland, Aoife Donnelly, Bruce Misstear, Brian Broderick
Reports
Air pollution is the primary environmental cause of premature death in the EU (European Commission, 2013) and the most problematic pollutants across Europe have consistently been oxides of nitrogen (e.g. nitrogen dioxide (NO2)), particulate matter (e.g. PM10, PM2.5) and ozone (O3). While measurements form an important aspect of air quality assessment, on their own they are unlikely to be sufficient to provide an accurate spatial and temporal description of the pollutant concentrations for exposure assessment and moreover they cannot provide information regarding future air quality. Annex XVI of 2008/50/EC requires member states …

Unregulated, privately owned water supplies, including groundwater wells, are relied upon extensively, particularly in rural and remote regions. While adequate stewardship behaviors (water testing, treatment, and maintenance) have been shown to decrease the incidence and frequency of faecal indicator organism (FIO) presence and, by extension, the risk of pathogenic ingress, contaminated private water supplies continue to constitute a significant public health risk. Recognizing that innovative approaches are needed to bolster well stewardship, this paper identifies and assesses 35 tools (smartphone and web-based applications) to better understand components, functionality, strengths, and weaknesses. Applications for both data collection and risk communication were …

With the increase of multimorbidity due to population ageing, managing multiple chronic health conditions is a rising challenge. Machine-learning can contribute to a better understanding of persons with multimorbidity (PwMs) and how to design an effective framework of care and support for them. We present a risk model of older PwMs that was derived from the TILDA dataset, a longitudinal study of the ageing Irish population. This model is based on a 26-nodes Bayesian network that represents patients possibly having one or more chronic conditions among diabetes, chronic obstructive pulmonary disease and arthritis, through a joint probability distribution of demographic, …
Assessment Of Physicochemical Characteristics, Thermal Stability And Release Profile Of Ascorbic Acid Microcapsules Obtained By Complex Coacervation, Michele Cristina Rodrigues Da Cruz, João Luiz Andreotti Dagostin, Camila Augusto Perussello, Maria Lúcia Masson
Assessment Of Physicochemical Characteristics, Thermal Stability And Release Profile Of Ascorbic Acid Microcapsules Obtained By Complex Coacervation, Michele Cristina Rodrigues Da Cruz, João Luiz Andreotti Dagostin, Camila Augusto Perussello, Maria Lúcia Masson

The aim of this study was to determine the physicochemical characteristics, thermal stability and release profile of ascorbic acid (AA) microcapsules obtained by complex coacervation. Gelatin and gum arabic were used as wall materials in concentrations of 2.5, 5.0 and 7.5 g% (w/v). The coacervate microcapsules were freeze-dried and assessed for physicochemical characteristics, thermal behavior and stability during 60 days of storage. The release profile was evaluated at different pH values (1.1, 2.2, 5.4, 7.4, 9.6 and 12). The encapsulation efficiency ranged from 27.3 to 93.8%. The microcapsules of AA presented good characteristics for application in food matrices, such as …

Decreased funding and shifting governmental priorities have resulted in a contraction of hydrometric measurement in many regions over the past two decades. Moreover, concerns exist with respect to appropriate data usage and (transboundary) exchange, in addition to the compatibility and extent of existing hydrometric datasets. These issues are undoubtedly magnified due to enhanced data demands and increased financial pressures on network managers, thus requiring new approaches to optimising the societal benefits and overall efficacy of hydrometric information for future socio-hydrological resilience. The current study employed a quantitative cross-sectional expert elicitation of 203 respondents to collate, analyse and assess hydrometric network …

Nanotechnology deals with the matter of atomic or molecular scale. Other factors that define the character of a nanoparticle are its physical and chemical properties, such as surface area, surface charge, hydrophobicity of the surface, the thermal stability of the nanoparticle, and its antimicrobial activity. A nanoparticle is usually characterized by using microscopic and spectroscopic techniques. Microscopic techniques are used to characterize the size, shape, and location of the nanoparticle by producing an image of the individual nanoparticle. Several techniques, such as scanning electron microscopy (SEM), transmission electron microscopy/high resolution transmission electron microscopy (TEM/HRTEM), atomic force microscopy (AFM) and scanning …
