Venezuela's humanitarian crisis, resurgence of vector-borne diseases, and implications for spillover in the region
2019
In the past 5–10 years, Venezuela has faced a severe economic crisis, precipitated by political instability and declining oil revenue. Public health provision has been affected particularly. In this Review, we assess the impact of Venezuela's health-care crisis on vector-borne diseases, and the spillover into neighbouring countries. Between 2000 and 2015, Venezuela witnessed a 359% increase in malaria cases, followed by a 71% increase in 2017 (411 586 cases) compared with 2016 (240 613). Neighbouring countries, such as Brazil, have reported an escalating trend of imported malaria cases from Venezuela, from 1538 in 2014 to 3129 in 2017. In Venezuela, active Chagas disease transmission has be…
Long Term Efficiency Analysis of Infiltration Trenches Subjected to Clogging
2018
Abstract: In recent years, limitations linked to traditional urban drainage schemes have been pointed out and new approaches were developed introducing more natural methods for retaining and/or disposing of stormwater. Such practices include infiltration and storage tanks in order to reduce the peak flow and retain part of the polluting components. The impact of such practices on stormwater quantity and quality is not easily assessable because of the complexity of physical and chemical processes involved. In such cases, integrated urban drainage models may play a relevant role providing tools for long term analysis. In this study, the effect of the clogging phenomenon has been assessed by m…
Urban water quality modelling: a parsimonious holistic approach for a complex real case study
2010
In the past three decades, scientific research has focused on the preservation of water resources, and in particular, on the polluting impact of urban areas on natural water bodies. One approach to this research has involved the development of tools to describe the phenomena that take place on the urban catchment during both wet and dry periods. Research has demonstrated the importance of the integrated analysis of all the transformation phases that characterise the delivery and treatment of urban water pollutants from source to outfall. With this aim, numerous integrated urban drainage models have been developed to analyse the fate of pollution from urban catchments to the final receiving …
Aerobic granular sludge treating shipboard slop: Analysis of total petroleum hydrocarbons loading rates on performances and stability
2018
Abstract The work focuses on the feasibility of treating slop with aerobic granular sludge. For this purpose, a 3.5 L granular sequencing batch reactor was activated and it was monitored for 156 days. The experimental campaign was divided into two periods, named Period I (100 days) and Period II (56 days). Total Petroleum Hydrocarbon (TPH) concentration in the slop was, on average, equal to 6.8 ± 1.5 mg L−1 and 13 ± 1.5 mg L−1 in Period I and Period II respectively. The obtained results during the first experimental period indicated that about 80 days were required to reach steady state with mature granules, when TPHs removal efficiency was approximately 90%. The results indicated that both…
Cultivation of granular sludge with hypersaline oily wastewater
2015
The time required to stabilise mature aerobic granules is rather variable. In addition, cultivation time and the structural characteristics of granules seem to be related to the nature of wastewater influent. Granular sludge has been used for the treatment of several industrial wastewaters, but nothing has been reported about wastewater characterized by the simultaneous presence of hydrocarbons and high chloride concentration. In this work, the authors analysed the granulation process and performance as well as the physical characteristics of aerobic granules in two Granular Sequencing Batch Airlift Reactors (GSBARs), fed with acetate-based synthetic wastewater in reactor 1 (R1) and with a …
El derecho de autonomia del paciente menor: Virtualidad de la mediacion en conflictos sanitarios con menores
2017
La Ley 41/2002, de 14 de noviembre reconoce el derecho a la autonomía del paciente en el ámbito sanitario, configurado como un derecho subjetivo en el marco de los derechos de la personalidad. Recientemente, las Leyes Orgánica 8/2015, de 22 de julio y Ley 26/2015 de 28 de julio han introducido importantes reformas en la consideración de la madurez de los menores para decidir determinados actuaciones que afectan a su persona, confiriendo a sus progenitores la facultad de consentir intervenciones sanitarias que puedan suponer grave riesgo para su vida o salud. Regulación ésta que plantea ciertos interrogantes a la hora de ofrecer soluciones a ciertos conflictos familiares y sanitarios que se …
Aerobic granular sludge treating high strength citrus wastewater: Analysis of pH and organic loading rate effect on kinetics, performance and stabili…
2017
Abstract In the present paper, the feasibility of citrus wastewater treatment with aerobic granular sludge sequencing batch reactors (AGSBR) was investigated. Two AGSBRs (named R1 and R2, respectively) were operated for 90 days under different organic loading rates (OLR) and pH in two experimental periods. The OLR ranged approximately between 3.0 kg TCOD m−3d−1 and 7 kg TCOD m−3d−1 during Period I, whereas between 7 kg TCOD m−3d−1 and 15 kg TCOD m−3d−1 during Period II. pH was maintained at 7.0 and 5.5 in R1 and R2, respectively. The results revealed that under high OLR and unbalanced feast/famine regime (Period I), the development of fast-growing microorganisms (fungi and filamentous bacte…
Challenges and opportunities for citrus wastewater management and valorisation: A review.
2022
Citrus wastewaters (CWWs) are by-products of the citrus fruit transformation process. Currently, more than 700 million of m³ of CWWs per year are produced worldwide. Until nowadays, the management of CWWs is based on a take-make-use-dispose model. Indeed, after being produced within a citrus processing industry, CWWs are subjected to treatment and then discharged into the environment. Now, the European Union is pushing towards a take-make-use-reuse management model, which suggests to provide for the minimization of residual pollutants simultaneously with their exploitation through a biorefinery concept. Indeed, the recovery of energy nutrients and other value-added products held by CWWs may…
Religious Engagement and the Migration Issue: Towards Reconciling Political and Moral Duty
2020
The increasingly acknowledged post-secular perspective has resulted in the emergence of some new approaches theorizing this phenomenon. One such approach has been the concept of religious engagement, which calls for the redefinition of the perception of religious non-state actors towards including them as important partners in the process of identifying and realizing political goals. According to this view, due to the multidimensional role played by religious communities and non-state religious actors, they need to be recognized as pivotal in creating a new form of knowledge generated through encounter and dialogue of the political decision-makers with these subjects. Among numerous others,…
ASSESSMENT OF BEACH LITTER ALONG THE COAST: CASE STUDY OF THE CITY OF CADIZ (SPAIN)
2016
The United Nations Environment Program defines as waste all the persistent marine debris deposited or abandoned in the sea (marine litter) and beach (beach litter) environment. Thus including all substances or products abandoned or involuntarily dispersed into the sea or on the coastline. It has been estimated that, all around the world, about 10 million tons of waste coming from domestic, commercial and industrial activities reach the seas every year. Moreover, waste floating adrift in the seas and oceans can be carried very far away, reaching different places from the ones they were originated. Further, damage may result to various human activities and equipment, such as navigation, energ…
