Background: The multidimensional assessment of frailty allows stratifying it into degrees
Desarrollo de la gestión medioambiental certificada en unidades hospitalarias y ambulatorias de hemodiálisis
2015
ResumenAntecedentesEl impacto ambiental de la hemodiálisis es destacado. Está destacando la actividad en este sentido incluso a nivel bibliográfico. Los sistemas de gestión medioambiental (SGMA) voluntarios, Environmental Management and Auditing System (EMAS) e International Organization for Standardization (ISO 14001), son instrumentos destacados para la protección medioambiental junto a legislación, impuestos y beneficios fiscales.ObjetivosConocer el grado de implantación de los SGMA en las unidades de hemodiálisis hospitalarias y ambulatorias del Sistema Nacional de Salud español, para disponer de un grupo de centros de referencia en gestión medioambiental en esta actividad sanitaria.Mét…

Greenhouse gases from wastewater treatment — A review of modelling tools
2016
Nitrous oxide, carbon dioxide and methane are greenhouse gases (GHG) emitted from wastewater treatment that contribute to its carbon footprint. As a result of the increasing awareness of GHG emissions from wastewater treatment plants (WWTPs), new modelling, design, and operational tools have been developed to address and reduce GHG emissions at the plant-wide scale and beyond. This paper reviews the state-of-the-art and the recently developed tools used to understand and manage GHG emissions from WWTPs, and discusses open problems and research gaps. The literature review reveals that knowledge on the processes related to N2O formation, especially due to autotrophic biomass, is still incompl…
Greenhouse gases from wastewater treatment plant: towards a new protocol for field measurements
2015
Greenhouse gases (GHGs) emission from wastewater treatment plants (WWTPs) represents an increasing interest in the water industry at the present moment. The biological processes needed for treating wastewater have been found responsible for the unintentional generation of GHGs, such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). The quality and quantity of a GHG emitted from a WWTP can significantly vary with the wastewater treated, the process configuration, and the strategies employed in process control. In the recent past, efforts for monitoring and accounting for GHGs emissions from WWTPs have considerably increased, and classifications of emission type were proposed t…
Effect of organic loading rate on the production of Polyhydroxyalkanoates from sewage sludge
2023
The aim of this work was to study the effect of organic loading rate on the production of Polyhydroxyalkanoates (PHA) from sewage sludge. Synthesis of PHA using sewage sludge as platform was achieved in this work. Three pilot-scale selection-sequencing batch reactors (S-SBR) were used for obtaining a culture able to accumulate PHA following a strategy of aerobic dynamic feeding (ADF) at different volumetric organic-loading-rate (vOLR): 1.3, 1.8 and 0.8 g COD L-1 d-1 for S-SBR 1, S-SBR 2 and S-SBR 3, respectively. Decreasing the vOLR enhanced the general performance of the process as for organic matter removal (from 99.2% ± 0.3% in S-SBR-3 to 92 ± 2 in S-SBR-2) while the opposite trend was r…
A Contribution to the analysis of the first Spanish public-private partnership in primary and specialized maternity care: a social network analysis a…
2021
The La Ribera University Hospital (Alzira, Valencia) was the first experience of public-private partnership in the Spanish National Health System. In addition to the need to coordinate two levels of health care (primary/specialised), two models of human resource management (public/private) had to be coordinated. To illustrate this complexity, the group of midwives in the health area has been taken, analysing their relational patterns through the methodological approach of Social Network Analysis. In terms of results, out of a population of 31 midwives, those of the public model occupy peripheral positions and cooperate poorly, both internally and externally. However, those of the private mo…
Interpreting and modelling field data for wastewater dispersion into sea trough dimensional analysis
2008
This paper deals with the mathematical and experimental characterization of a coastal urban wastewater discharge in the South Tyrrhenian Sea, namely the Golfo di Palermo, western Sicily (Italy). The stretch of water lying before the central part of the capital town receives the wastewater originating from about 200 000 inhabitants. The sewage is currently still discharged on-shore without any prior treatment by a free-surface outfall called “Porta Felice”. The Municipality is currently implementing a plan to connect the sewerage system of these areas to the main wastewater treatment plant; at the moment, however, no mitigation measure has been applied yet and the quality of the Gulf is stil…
Multiregression Analysis of the Kinetic Constants in Ephemeral Rivers: The Case Study of the Oreto River
2018
Profuse efforts have been committed to develop efficient tools to measure the ecological status of the receiving water body quality state. The recurrence to mathematical models as support tools for the receiving water body quality assessment can be an optimal choice. Indeed, mathematical models can allow to build-up the cause effect relationship between polluting sources and receiving water quality. Regarding the river water quality modelling, two different kinds of river can be single out: large and small rivers. In the modelling approach, the main differences between the two types of river are reflected in the model kinetic constants. Indeed, the main quality processes which control and g…
An urban drainage stormwater quality model: model development and uncertainty quantification
2010
Summary The evaluation of urban stormwater quality is of relevant importance for urban drainage, and mathematical models may be of great interest in this respect. To date, several detailed mathematical models are available to predict stormwater quantity–quality characteristics in urban drainage systems. However, only a few models take sewer sediments into account, considering their cohesive-like properties that influence the build-up process of the pollutant load. Furthermore, the model data requirements, especially for the quality aspects, are extensive, which limit their applicability and affect model results with large uncertainty. Uncertainty analysis provides a measure or index regardi…
