Background Primary care physicians have been present on the frontline during ongoing pandemic, adding new tasks to already high workloads. Our aim was evaluate burnout in primary COVID-19 as well associated contributing factors. Methods Cross-sectional study with an online questionnaire disseminated through social media, applying snowball technique. The target population working Portugal first outbreak of pandemic. In addition sociodemographic data, collected responses Copenhagen Burnout...

The COVID-19 pandemic affected the operation of water utilities across world. In context utilities, new protocols were needed to ensure that employees can work safely, and service is not interrupted. This study reports on how operations 27 worldwide by pandemic. Interviews conducted between June October 2020; respondents represent varied in population size, location, customer composition (e.g., residential, industrial, commercial, institutional, university customers). Survey questions...

Because the provision of an adequate and reliable water supply system involves a very high level investment, it is essential that layout design such systems are carefully planned operation their hydraulic infrastructures properly managed. This paper describes simulated annealing method can be used to find least-cost for gravitational looped distribution network. Simulated heuristics have proved extremely efficient in solving classic combinatorial problems as “traveling salesmen” problem. To...
Three optimization models are proposed to select the best subset of stations from a large groundwater monitoring network: (1) one that maximizes spatial accuracy; (2) minimizes temporal redundancy; and (3) model both accuracy redundancy. The solved with simulated annealing, along an algorithm parametrization using statistical entropy. A synthetic case-study 32 is used compare results when 17 be chosen. first tends distribute evenly in space; second clusters areas higher variability; third...
Abstract This paper presents a simulated annealing multiobjective algorithm developed to include novel features for promoting the convergence toward best Pareto front that shows diversity and uniformity in distribution of solutions. The new algorithm, MultiObjective Simulated Annealing with Generation Reannealing procedures (MOSA‐GR), is trajectory‐based where, first phase, diversified generation strategies are used define candidate solutions at different stages search procedure. In second...
In the face of a highly uncertain future, there is need for water utilities to develop structured approaches long-term strategic design distribution networks (WDNs). A new conceptual framework developing an integrative approach based on multicriteria decision analysis (MCDA), embracing optimization model size flexible alternatives, proposed. The solutions are evaluated through MCDA all criteria (investment costs, carbon emissions, resilience, and reliability WDNs) across scenarios generated...
Abstract This paper presents and discusses concepts, models, methods for defining strategies, plans, actions to achieve the sustainable development of water environmental systems in a context uncertainty. The complexity such systems, including human natural landscapes their interactions, is tremendous challenge with regard decision-making processes. future that now being designed involves myriad uncertainties, climate non-climate related, request comprehensive decision frameworks involving...
In the last three decades optimal design of water distribution systems problem has been studied by a great many researchers, and this resulted in development large number models application optimization techniques. The these infrastructures is based on future predefined perfectly known working conditions for networks, premise that may direct process to solutions which, although imposed scenario, perform badly if reality turns out be significantly different. fact can disrupted accidents such...
Water supply systems have to satisfy water needs in terms of quantity and quality. The constant changes urban areas require the regular adaptation infrastructure meet new circumstances. However, decisions design operate networks be taken under uncertainty. Flexibility is thus key more robust confident decisions. An approach called real options (ROs) can used these situations. This makes it possible use adaptive strategies decision process. Some delayed pending future conditions. distribution...
Water distribution network design is a complex multi-objective optimization problem and evolutionary algorithms (MOEAs) such as NSGA II have been widely used to solve this problem. However, networks get larger, struggles find the diverse uniform solutions that are critical in optimization. This research proposes an improved version of uses three new-generation methods target different regions Pareto front thus increase number regions. These include saving archive, local search around extreme...
Abstract: Planning solutions for wastewater system problems are often sought at a local level—that is, each city develops its own solution. However, in many cases, it would be possible to find that better both from the economic and environmental viewpoints if they were looked regional level. In this article, we present an efficient simulated annealing (SA) algorithm solving planning model. The model is aimed determining minimum‐cost configuration will drain generated by population centers of...
This paper describes a simulation-optimization model aimed at helping water utilities determine the best way to operate large-scale multisource water-supply systems. The operation of systems is optimized taking into account principal planning objectives defined for interventions that include reducing operating costs, satisfying demand, delivering appropriate quality, and not prompting use emergency sources. allows these may be completely fulfilled in critical circumstances (e.g., droughts)...
Rain gauge monitoring networks are highly important for precipitation and erosion estimation. In general, measurement accuracy depends on the as well network size design. This paper proposes a method assessing optimal location of new stations within an existing rain network. It takes account prediction rainfall erosivity. A known geostatistical variance-reduction is applied jointly with simulated annealing algorithm objective function minimization. With respect to first objective, kriging...
The wastewater generated in urban areas is one of the main sources water pollution, particularly regions characterized with large population density and high urbanization degree.
