ABSTRACT Vulnerable regions to drought require resource allocation to develop projects to combat low rainfall negative impacts. In this perspective, this study proposes a multicriteria sorting model to categorize municipalities affected by drought in order to allocate resources according to criticality. The proposed model is based on the FlowSort method for sorting municipalities into highly critical, moderately critical, and slightly critical levels to cope with drought. The model was applied in the Apodi-Mossoró river basin in Rio Grande do Norte, Brazil, for sorting 14 municipalities. The findings revealed that the public administration could effectively focus its resources on municipalities experiencing more severe drought conditions. Thus, the public administration can develop strategies, public policies, and actions in coping with extreme difficulty. impacts perspective criticality ApodiMossoró Apodi Mossoró Norte Brazil 1 conditions Thus strategies policies difficulty

ABSTRACT Waste sorting is a core element for adding value to the recycling chain. Exploring and prioritizing alternatives regarding its expansion and improvement is very challenging. This study proposes a multi-methodological approach through the integration of a Problem Structuring Method (PSM) and a multicriteria method (MCDA/M) to support decision-making in the solid waste management context. The developed model uses Soft Systems Methodology (SSM) in the problem structuring stage to explore the problematic situation and identify alternatives. Preference modeling was conducted in a flexible and interactive manner, aided by FITradeoff method to rank the identified alternatives and obtain a recommendation. The proposed model was developed for a real case study in Brazil. In the elicitation process, the decision maker answered 9 questions to obtain the ordering of alternatives. This work seeks to enrich the literature proposing the successful application of an innovative model in the waste management context, especially regarding waste sorting. chain challenging multimethodological multi methodological PSM (PSM MCDA/M MCDAM MCDA M (MCDA/M decisionmaking making context SSM (SSM manner recommendation Brazil process

Abstract Paper aims The objective of this work is to develop a comprehensive group decision model to support public managers in choosing the best location for the construction of landfills based on a strategy known as “regionalization” (collaborative construction of landfills). Originality The proposed group decision model innovates when considering the regionalization strategy in a multi-DM environment based on a framework for choosing a voting procedure. Research method The model is divided into three stages: (i) individual assessment of preferences; (ii) choosing a voting procedure; and, (iii) group aggregation and recommendation. First, it uses MCDA/M to elicit DMs' preferences and obtain individual rankings; then, a framework for choosing a voting procedure (VP) to aggregate individual preferences and obtain a collective choice. Main findings The main findings indicate that the proposed model that uses PHOMETHEE-ROC and a VP proposes a recommendation that is of everyone’s interest in the presented multi-DM landfill site selection problem presenting its feasibility and applicability. Implications for theory and practice It encourages public managers to use a formal approach to make a comprehensive analysis of solid waste management practices. Furthermore, the proposition of an integrative framework to support group decision analysis by using MCDA/M and VP. “regionalization collaborative landfills. . landfills) multiDM multi DM stages i (i ii (ii iii (iii First MCDAM MCDA M DMs rankings then (VP choice PHOMETHEEROC PHOMETHEE ROC everyones everyone s applicability practices Furthermore

Abstract Paper aims The objective of this research is to propose a multicriteria negotiation model for selecting a sustainable packaging supplier in the food industry. The model aims to minimize the environmental, social and economic impacts of the production process of plastic while ensuring the operational criteria of packaging. Originality Despite the high number of scientific research using multicriteria decision-making suggested to select a supplier, the proposed negotiation model is innovative as it includes green manufacturing as a criterion for negotiation, alongside price and delivery time, to promote sustainable supply chain management. Research method The research method involves three stages: pre-negotiation, negotiation (based on FITradeoff), and post-agreement. The proposed model is illustrated using a case study of a Colombian slaughterhouse that needs to select a sustainable packaging supplier for the next two years. Main findings The main findings indicate that the proposed model that uses the FITradeoff for negotiation solves the problem of selecting sustainable packaging suppliers while promoting sustainable supply chain management in the agribusiness sector. Implications for theory and practice The model has implications for both theory and practice. It encourages interdependent companies to collaborate and enhances efficiency in greener terms for supply chains, buyer and seller firms. The proposition of an original integrative negotiation protocol for selecting sustainable suppliers in agribusiness can provide enterprises with a set of negotiation parameters to achieve successful sustainable supply chain management. industry environmental decisionmaking decision making time stages prenegotiation, prenegotiation pre pre-negotiation based FITradeoff, , FITradeoff) postagreement. postagreement post agreement. agreement post-agreement years sector chains firms

ABSTRACT Mobility and urban planning are challenging tasks for public authorities, especially in densely populated cities. The city of Olinda, Pernambuco-Brazil, faces problems in traffic and access to places, making it necessary to identify new alternatives to improve urban mobility in Olinda. This study presents a decision support model to develop and evaluate new alternatives to do so. In the decision frontend, Value-Focused Thinking was applied to identify objectives and their respective attributes, and to create alternatives based on these objectives. As a result, 69 alternatives were generated, concatenated into 48, and categorized into four groups. Group 1 and Group 2 comprise 30 alternatives that serve the city’s north side; however, they attend to the neighborhoods separately. Group 3 comprises 11 alternatives routes that serve the two areas together, this being the focus of this study, and Group four consists of 7 short-term alternatives. In the decision backend, the FITradeoff for ranking problematic method was applied to evaluate the 11 alternatives of Group 3. The study showed that it would be possible to improve mobility more urgently by making a few improvements to the itinerary on the existing routes. Therefore, the study discusses the possibility of starting to make progress in the urban system of the city by using fewer complex alternatives compared to setting up new routes. authorities cities Olinda PernambucoBrazil, PernambucoBrazil Pernambuco Brazil, Brazil Pernambuco-Brazil places so frontend ValueFocused Value Focused attributes result 6 generated 48 groups citys s side however separately together shortterm short term backend Therefore 4

BACKGROUND In Brazil, the yellow fever virus (YFV) is maintained in a sylvatic cycle involving wild mosquitoes and non-human primates (NHPs). The virus is endemic to the Amazon region; however, waves of epidemic expansion reaching other Brazilian states sporadically occur, eventually causing spillovers to humans. OBJECTIVES To report a surveillance effort that led to the first confirmation of YFV in NHPs in the state of Minas Gerais (MG), Southeast region, in 2021. METHODS A surveillance network was created, encompassing the technology of smartphone applications and coordinated actions of several research institutions and health services to monitor and investigate NHP epizootics. FINDINGS When alerts were spread through the network, samples from NHPs were collected and YFV infection confirmed by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and genome sequencing at an interval of only 10 days. Near-complete genomes were generated using the Nanopore MinION sequencer. Phylogenetic analysis indicated that viral genomes were related to the South American genotype I, clustering with a genome detected in the Amazon region (state of Pará) in 2017, named YFVPA/MG sub-lineage. Fast YFV confirmation potentialised vaccination campaigns. MAIN CONCLUSIONS A new YFV introduction was detected in MG 6 years after the beginning of the major outbreak reported in the state (2015-2018). The YFV strain was not related to the sub-lineages previously reported in MG. No human cases have been reported, suggesting the importance of coordinated surveillance of NHPs using available technologies and supporting laboratories to ensure a quick response and implementation of contingency measures to avoid YFV spillover to humans.

RESUMO: Bactérias da Classe Mollicutes estão associadas à infecção intramamária e diminuição da produção leiteira. O objetivo deste estudo foi investigar a ocorrência de Mollicutes e elucidar seus fatores de risco em rebanhos leiteiros do sudeste brasileiro. Para isso, amostras de leite de 387 vacas em lactação dos estados de Minas Gerais, Rio de Janeiro e São Paulo foram submetidas à reação em cadeia da polimerase (PCR) para detectar Mollicutes. Espécies de Mycoplasma foram investigadas nas amostras positivas por PCR, incluindo Mycoplasma bovis, M. alkalescens, M. bovigenitalium, M. bovirhinis, M. arginini e A. laidlawii. Foi aplicado um questionário epidemiológico para a coleta de dados sobre possíveis fatores de risco, que foram avaliados pelo teste de Qui-Quadrado de Pearson seguido de odds ratio (P≤0.05). Mollicutes foram detectados em 21% (4/19) dos rebanhos e 4% (16/387) dos animais, enquanto 1% (5/387) destes foram positivos para m. bovis, 3% (11/387) para m. arginini, sendo todas as amostras negativas para os demais agentes. Rebanhos com mais de 150 animais [OR=3,51 (95% IC 1,11-11,08)], ordenha manual [OR=9,97 (95% IC 2,80-35,49)] e ausência de linha de ordenha [OR=6,54 (95% IC 1,92-22,29)] foram considerados fatores de risco. A presença dessas condições pode favorecer a infecção intramamária por Mollicutes em rebanhos leiteiros no sudeste do Brasil. Este é o primeiro relato de M. bovis no Rio de Janeiro e M. arginini nos estados estudados.

ABSTRACT: Bacteria of Mollicutes Class are associated with intramammary infection and decrease in milk production. This study investigated the occurrence of Mollicutes and elucidated their risk factors in dairy herds from Southeast Brazil. For this, milk samples from 387 lactation cows from Minas Gerais, Rio de Janeiro and São Paulo States were subjected to the polymerase chain reaction (PCR) to detect Mollicutes. Species of Mycoplasma were investigated in Mollicutes positive samples by PCR, including Mycoplasma bovis, M. alkalescens, M. bovigenitalium, M. bovirhinis, M. arginini and A. laidlawii. An epidemiological questionnaire was applied to collect data on possible risk factors, which were assessed using Pearson’s Chi-square test followed by odds ratio (P≤0.05). Mollicutes were reported in 21% (4/19) of the herds and 4% (16/387) of the animals, while 1% (5/387) were positive for M. bovis and 3% (11/387) for M. arginini. All samples were negative to the other agents. Herds with more than 150 animals [OR=3.51 (95% CI 1.11-11.08)], manual milking [OR=9.97 (95% CI 2.80-35.49)] and not-milking animals with mastitis last [OR=6.54 (95% CI 1.92-22.29)] were risk factors. The presence of these conditions may favor intramammary infection by Mollicutes in dairy herds from Southeast Brazil. This is the first report of M. bovis in Rio de Janeiro and M. arginini in the studied states.

RESUMO O desenvolvimento de alternativas para o aproveitamento da casca de coco possibilita a redução da disposição inadequada de resíduos sólidos e proporciona uma nova opção de rendimento junto aos locais de produção. O presente trabalho tem como objetivo avaliar o potencial de extração de taninos do mesocarpo de coco verde e sua capacidade adesiva. A extração do tanino foi feita em água com adição de sulfito de sódio a 0%, 1%, 5% e 8%. Em seguida, observou-se qual dessas extrações demonstrou melhores rendimentos e características para ser usado como agente adesivo. A concentração de sulfito de sódio a 5% possibilitou maior rendimento na extração de taninos. Quando comparado com fenol-formaldeído, o tanino apresentou características adesivas similares como viscosidade 153,84 cp e teor de sólido 54,57%. Para a análise de espectroscopia FT-IR foram utilizadas amostras secas do mesocarpo do coco. Os picos observados no espectro de infravermelho do mesocarpo do coco verde são característicos de taninos encontrados em biomassa, apresentando características químicas desejáveis para ser utilizado como agente adesivo. O mesocarpo do coco é um material com potencial para extração de taninos a ser empregados na colagem de painéis.

ABSTRACT The development of alternatives for reuse of coconut shell allows inadequate solid residues disposal reduction and provides a novelty option close to the production sites. This paper aims to evaluate the tannin extraction potential of the green coconut mesocarp, as well as its adhesive capacity. Tannin extraction was performed with sodium sulfite diluted in water at 0%, 1%, 5% and 8% concentrations. It was observed which extraction resulted in better yield and characteristics to be used as an adhesive agent. The concentration of sodium sulfite at 5% allowed higher yields of tannin extraction. When compared to phenol formaldehyde, the tannin had similar adhesive characteristics such as 153.84 cp viscosity and 54.57% solid content. For the FT-IR spectroscopy analysis, dry samples of the coconut mesocarp were used. The peaks observed in the infrared spectrum of the green coconut mesocarp are characteristic of tannins found in biomass, presenting desirable chemical characteristics to be used as an adhesive agent. The coconut mesocarp is a material with potential for tannin extraction, making it suitable to be used in the gluing of panels.

Abstract A correct Network Segmentation (NS) is necessary to perform proper maintenance activities in water distribution networks (WDN). For this, usually, isolation valves are allocating near the ends of pipes, blocking the flow of water. However, the allocation of valves increases costs substantially for the water supply companies. Additionally, other criteria should be taking account to analyze the benefits of the valves allocation. Thus, the problem is to define an alternative of NS which shows a good compromise in these different criteria. Moreover, usually, in this type of decision, there is more than one decision-maker involved, who can have different viewpoints. Therefore, this paper presents a model to support group decision-making, based on a multi-criteria method, in order to support the decision making procedure in the NS problem. As result, the model is able to find a solution that shows the best compromise regarding the benefits, costs, and the decision makers' preferences.

Abstract The losses in the urban water supply networks have become a growing concern. There are several alternatives for the quantification, detection and monitoring of water losses. However, in general, water companies have budgetary and other constraints that hinder implementation. Therefore, this paper presents a model to aid the selection of a subset of preventive maintenance actions to control water losses while accounting for the water companies’ restrictions. The model combines an additive multi-attribute value analysis by applying the SMARTER method to evaluate alternatives with Integer Linear Programming (ILP). The model shows to be efficient in order to achieve a portfolio of preventive maintenance actions, particularly when the decision maker considers that, there is a compensation for attribute evaluations.

Além dos custos diretos, a ocorrência de rupturas na rede de distribuição de água tem sempre consequências sociais associadas, principalmente pela interrupção do abastecimento de água durante a reparação da infraestrutura. Nesses casos, a setorização da rede torna mais fácil qualquer atividade de manutenção. Porém, além do elevado custo da alocação de válvulas de fechamento, as normas brasileiras sobre setorização das redes dizem respeito apenas a questões técnicas que devem ser obedecidas. Portanto, propõe-se uma setorização que também incorpore a intensidade do impacto gerado pela falta de água em cada trecho da tubulação. Para medir esse impacto é proposto um índice de priorização que agrega as características das unidades consumidoras por meio do método multicritério SMARTER. Assim, desenvolve-se um modelo de setorização para manobra que leva em consideração esse índice, buscando a maximização dos benefícios gerados e a minimização do número de válvulas de fechamento.

In addition to incurring direct costs, the occurrence of breaks in a water distribution network always has associated social consequences, mainly related to the interruption of water supply during infrastructure repair. In these cases, network segmentation facilitates maintenance activities. However, the Brazilian norms, about network segmentation, relate only the technical guidelines that must be followed. We therefore propose network segmentation based on the impact intensity caused by a lack of water in each pipe segment. To measure this impact, we propose a priority index that aggregates the characteristics of consumer units by the SMARTER multicriteria method. Taking this index into account, we propose a segmentation model for water distribution networks that seeks to maximize the benefits generated and to minimize the number of isolation valves.

Any interaction involving individuals, whose objectives are conflicting with each other, may establish a negotiation process. In a negotiation, each party should develop his/her own strategy and, normally, a win-lose vision is frequently adopted. The main consequence of this behavior is a result, in which both parties lose, especially when the negotiation involves more than one aspect, such as negotiations resulting from purchases of material for construction industry, where aspects like price, quality and lead-time should be considered. Most of the negotiation involving construction industry adopts a win-lose vision; and, commonly, only the issue price is considered. The goal of this paper is to propose a framework to support negotiations between two parties (buyer and seller) in the supply chain of construction industry. The combination of a win-win strategy with a multicriteria analysis produces a best compromise solution for both parties. A simulation of negotiation using realistic data is presented.

A structured evaluation of the construction industry's suppliers, considering aspects which make their quality and credibility evident, can be a strategic tool to manage this specific supply chain. This study proposes a multi-criteria decision model for suppliers' selection from the construction industry, as well as an efficient evaluation procedure for the selected suppliers. The model is based on SMARTER (Simple Multi-Attribute Rating Technique Exploiting Ranking) method and its main contribution is a new approach to structure the process of suppliers' selection, establishing explicit strategic policies on which the company management system relied to make the suppliers selection. This model was applied to a Civil Construction Company in Brazil and the main results demonstrate the efficiency of the proposed model. This study allowed the development of an approach to Construction Industry which was able to provide a better relationship among its managers, suppliers and partners.
