Summary: The study showed that biomass productivity in photobioreactors increased as water depth decreased, but a decrease in bacterial community evenness may lead to a reduction in nutrient removal. Heterotrophs and phototrophs, mainly from the family Rhodobacteraceae, dominated bacterial diversity, and community changes were driven by various environmental factors and biological interactions.

Summary: An integrated electrocoagulation-membrane (ECM) system is proposed for treating dye wastewater in the textile industry. The study uses statistical techniques and JMP software to evaluate the feasibility and cost-effectiveness of the system. The results show that the ECM system has lower costs and can effectively remove dyes, but the standalone EC system is more economically feasible.

Summary: This invited review paper presents the state-of-the-art applications in energy-water system optimization and discusses the potential benefits for facility custodians in urban precincts. The paper explores optimization modeling frameworks for integrated precinct-scale energy-water system planning and identifies underlying optimization methods for cost-effectiveness and system reliability. The paper also discusses the challenges in formulating an optimization problem that reveals synergies between energy and water and proposes classical and heuristic techniques for solving complex optimization problems. Additionally, the paper addresses the uncertainties in energy-water demand/supply and suggests parameterizing random perturbation sets to realistically characterize these uncertainties. The paper highlights the importance of adopting robust approaches for extreme load/cost volatility situations and suggests physics-informed data-driven optimization modeling as a promising approach.

Summary: Currently, decision support tools for wastewater treatment and resource recovery lack accurate databases for evaluating treatment processes. This study proposes a grey-box modelling approach for nanofiltration to address this issue and demonstrates its effectiveness. The study shows that the nanofiltration model can accurately predict flux and solute removal, and its applicability for resource recovery was evaluated through an optimization model.

Summary: This paper presents an ex-post analysis on the impact of electricity subsidy reform in Iran from 1984 to 2017. The analysis shows that subsidy reform could have reduced electricity consumption by 22% and increased the share of renewable energy in power generation from 5% to 15%. It also reveals that the reform would have saved $69 billion and avoided 944 million tons of CO2 emissions, while a five-year delay in subsidy removal causes an additional 100 million tons of CO2 emissions.

Summary: The study examined the environmental sustainability of wastewater treatment through phosphate and ammonia chemical precipitation, identifying magnesium dosage and contact time as environmental hotspots. It found that raising wastewater temperature to promote ammonia stripping was environmentally unsound. Results suggest that struvite precipitation can act as a fast, efficient, and environmentally friendly pre-treatment step with low environmental impact when using low contact time and magnesium dosage.

Summary: This paper explores the use of natural language processing techniques to predict structured metadata in failure notifications. It highlights the challenges posed by the technical nature of the texts and the use of sentence fragments and abbreviations. The authors demonstrate that considering the dependencies between different components of the metadata and treating the prediction problem as a multidimensional classification problem can improve label prediction reliability.

Summary: In this article, the relationships between the fuzzy betweenness relations and three important mathematical notions, such as fuzzy interval operators, fuzzy partial orders, and fuzzy Peano-Pasch spaces, are explored in the setting of complete residuated lattices. The resulting category of fuzzy betweenness relations with respect to a fuzzy equivalence relation is shown to be isomorphic to that of geometric fuzzy interval spaces. A fuzzy partial order is constructed from a fuzzy betweenness relation, and its relationships are analyzed in depth. Furthermore, the concept of a fuzzy betweenness field is introduced, and it is shown that a vector space over a fuzzy betweenness field can yield a fuzzy Peano-Pasch space in the setting of completely distributive lattices.

Summary: In this paper, the concept of a t-norm on bounded pseudo-ordered sets and bounded trellises is introduced, along with some basic examples. The impact of abandoning transitivity is discussed, highlighting that the meet operation is not a t-norm on a proper bounded trellis, and there may be no or multiple maximal t-norms. A generic construction method is provided to extend a t-norm on an interior range of a given perpendicular to-semi-trellis to the entire trellis, with a specific instantiation based on a finite sub-trellis of right-transitive elements. The focus is also on bounded pseudo-chains and modular trellises. (c) 2023 Elsevier B.V. All rights reserved.

Summary: This paper discusses two-dimensional cellular automata on a triangular grid that maintain the sum of all cell states. To investigate such automata, the split-and-perturb decomposition method is applied to triangular grids, which was originally developed for square grids. This results in a new mathematical tool that can enumerate k-ary number-conserving cellular automata on a triangular grid, regardless of the value of k.

Summary: Water scarcity and droughts are becoming more serious issues globally. This study presents a decision support tool that can automatically compute the optimal reclaimed water network for a given scenario, utilizing open data sources, graph theory, and greedy optimization algorithms. The tool provides information on reclaimed water quantity, pipe lengths and diameters, storage tank locations and sizes, population served, and construction costs. The tool's usefulness is demonstrated in two different cities. The estimated construction cost of the optimal water reclaimed network for a city with approximately 100,000 inhabitants is in the range of euro0.17-0.22/m(3) (with a payback period of 30 years).

Summary: The recovery of nutrients from wastewater for agricultural fertilization is an interesting approach. In this study, wastewater recovered magnesium phosphate salts were used as draw solution in a forward osmosis system to extract water and produce a nutrient solution for hydroponic lettuce cultivation. The low solubility of the magnesium phosphate salts was overcome by acid dissolution using citric and nitric acids.

Summary: In this paper, non-uniform elementary cellular automata on the infinite grid in the context of number conservation are studied. The study provides a comprehensive description of these automata. Previous research only focused on finite grids and derived hypotheses based on computer experiments. It is found that when considering number conservation for non-uniform cellular automata, the infinite grid cannot be treated as a limiting case of finite grids.

Summary: Individual biology influences population dynamics dependent on the environment through life history. Recent research has integrated metabolic theory with individual-based models to explore the link between individual physiology and demography. However, current population models do not consider individual behaviors, relying instead on imposed population-level relationships. This study proposes extending the model to include individual-scale behaviors and demonstrates its effectiveness in simulating consumer dynamics in a heterogeneous environment.

Summary: This paper discusses two-dimensional cellular automata with rotation symmetry and number conservation. It is shown that if the number of states k is smaller than or equal to six, then each rotation-symmetric number-conserving cellular automaton is isomorphic to some k-ary one. However, an example of a seven-state rotation-symmetric number-conserving cellular automaton is provided in this paper, which demonstrates the importance of not only focusing on cellular automata with {0, 1, ..., k-1} as state sets.

Summary: This research analyzes the construction of critical discourses on tourism in the emerging urban satellite destination of Girona. The study examines the transformation of neighborhood identities, banalization and thematization, massification of public spaces, increasing property costs, and lack of tourism management. The findings also suggest a connection between the critical discourse found in Barcelona and local residents in Girona. The research contributes to understanding the complexities of critical discourses on the negative effects of tourism and their dissemination among different destinations.
