A P2P-based Infrastructure for Virtual-Enterprise ́s Supply-Chain Management
No full textThis paper proposes and describes a prototype of a peer-to-peer based infrastructure to support virtual enterprise’s supply chain management. Because of a virtual enterprise is composed of autonomous, distributed, and continuously evolving entities, we have naturally modelled each business entity like a peer’s agent platform that can play several roles according to the task to be fulfilled. To this end, we describe and apply such roles, required to the organizational architecture, into a virtual storehouse scenari
Reclaimed wastewater reuse impacts: from literature data gaps to integrated risk modelling
No full textThe complexity and the inherent interconnection of the reclaimed wastewater reuse (RWW) system requires the proper quantification of its advantages and drawbacks. In this context, water utilities and decision makers would benefit from a comprehensive risk-based framework of models aimed at the assessment of its associated impacts.
In this work, a critical literature review on the models available for the assessment of RWW reuse impacts is performed to highlight which gaps need to be filled and indicate the future research directions. A simplified approach for evaluating and integrating different type of risks was proposed to address the prioritization of critical endpoints and contaminants within regulations
From Literature Gaps to Integrated Risk Assessment: Unveiling the Complexity of Wastewater Reuse Impact Models
No full textThe complexity and inherent interconnection of the reclaimed wastewater (RWW) reuse system requires a thorough assessment of both its positive and negative impacts. In fact, either the reuse is direct or indirect, on one hand, RWW provides essential resources for crops, like water and nutrients, on the other hand, it spreads contaminants that pose potential risks to both human health and the environment. In this context, water utilities and decision makers would benefit from a comprehensive risk-based framework of models aimed at the assessment of its associated impacts.
This paper critically reviews the different models that are available for the assessment of RWW reuse impacts, focusing on: (i) the type of impacts, (ii) the evaluated compartments, and (iii) the targeted variables. This review identifies gaps in the evaluation of RWW reuse impacts and outlines future research directions to bridge these gaps.
Finally, a simplified approach is proposed for integrating and evaluating three types of risk due to the presence of contaminants of emerging concern (CECs) in RWW for indirect reuse: human health risk, environmental risk and risk related to antibiotic resistance development

Socially-Based Design meets Agent Capabilities
No full textThe area of multi-agent system is promising in order to help complex system development, indeed, currently, several agent oriented software methodologies have been proposed. Such methodologies mainly focus on their abstraction ability in order to both easily manage the system complexity and easily isolate the stakeholders’ requirements that affect the system architecture. On the contrary, this paper also deals with the above issues, but it pays more attention to the characterization of "intelligent" agent capabilities. Specifically, to deliver on such a task, the paper focuses on the socially-driven approach of Tropos software design methodology in order to build up an agent-based information system prototyp
Assessing the Risk of Wastewater Reuse in Agriculture: Is Irrigated Crops’ Food the main Exposure Route for Alkylphenols compared to Drinking Water?
No full textThe excessive exploitation and contamination of freshwater pose threats to public health, leading to cross-contamination among interconnected environmental compartments such as freshwater, soil and crops. In particular, contaminants of emerging concern (CECs) originating from human activities are not completely removed by wastewater treatments plants and the effluent discharged in surface waters as well as wastewater reuse determine their presence in drinking water (DW) sources, soil and crops intended for human consumption. Bisphenol A (BPA) and nonylphenol (NP) have been frequently detected in DW and food, namely the major exposure sources for humans, with adverse effect, respectively, on immune and renal systems. Currently, health risk assessments focus solely on individual exposure sources without considering the multiple exposure routes humans are exposed to. We propose an integrated approach to quantitatively assess health risk from CECs considering multiple exposure from both DW and food consumption across the relevant interconnected environmental compartments. This procedure was applied to BPA and NP to calculate their probabilistic Benchmark Quotient (BQ), demonstrating its ability to quantitatively apportion the risk between contaminants and exposure sources. Scenario analyses simulating BPA and NP reduction strategies were conducted, underscoring the quantitative risk assessment potential as a decision support tool for prioritizing mitigation actions. The estimated health risk from BPA was significantly higher compared to NP, with the consumption of food from edible crops posing a greater risk than tap water. Therefore, prioritizing mitigation actions for the prevention and removal of BPA from food would be more effective in minimizing the health risk
