    Abstract Environmental Sustainability is one of the ‘Grand Challenges’ for manufacturing success in the 21st century. The present article mainly focuses on energy use during the manufacturing steps used for assembling products. In particular, industry still needs systematic and reliable ways to capture information for ultimately accounting for energy efficiency in manufacturing processes. For that purpose, an information model in the form of a formal ontology was created using information elements as building blocks, which emerge from manufacturing process models, supply chain operations, manufacturing process parameters, 3D form features and exergy-based thermodynamic analysis. These information elements were integrated by means of semantic relationships in an ontology. Once this information model was constructed, an application example of a welded hull panel assembly was used for verification of the model's representativeness and completeness. Results show that it is feasible to correlate all required data by means of semantic relationships for estimating energy efficiency indicators prior to physical prototyping, or ultimately comparing different alternatives for manufacturing processes regarding energy efficiency. However, manufacturing processes must be described in detail in order to allow energy efficiency analyses. In addition, geometric models need to be able to represent form features that can best relate to specific manufacturing process parameters. And finally, energy efficiency indicators, such as the degree-of-perfection can be derived from a comprehensive thermodynamic analysis, to be performed in each individual process step. Results indicate it is possible to provide an information structure for the calculation of the degree-of- perfection associated with an exergy-based thermodynamic analysis in assembly processes. Therefore, it has the potential to serve as a basis for a unifying framework for developing software applications that could allow the calculation of the degree of perfection in manufacturing operations. In addition, the resulting information model may facilitate data integration in the extended enterprise environment as well as the development of standards that can lead to seamless interoperability of manufacturing information systems. This paper presents the means by which energy efficiency can be accessed directly from an integrated semantic model, and opens the possibility to be extended for many different sorts of manufacturing processes.

    Abstract Municipal Solid Waste Management is yet to be eco-effectively performed, especially in developing countries. In Brazil, a considerable fraction of waste has been improperly landfilled, generating environmental, social and economic problems. In 2018, the government of the state of Paraná released a revised version of its waste management plan, defining improvement strategies to be gradually implemented until 2038. However, these strategies' eco-effectiveness has not been forecasted, nor the plan was deployed to the regional level. This research aims to fill this gap, downscaling the plan to the region of Norte Pioneiro, simulating its implementation and monitoring environmental and economic benefits. The dynamics of waste generation, collection and disposal are investigated using an agent-based model, considering the four population growth scenarios addressed in the plan. Targets for strategies of waste reduction, collection, source-separation and charging of waste fees are modelled. Multiple simulation runs were performed and outputs assessed and discussed. Results show that, if the plan is thoroughly implemented since 2020, at least 650 kilotons of avoided CO

Implications from the strategies proposed in the plan are highlighted, and recommendations to improve the plan's eco-effectiveness are outlined.

    Abstract Lymphovascular invasion (LVI) is a relevant prognostic factor in germ cell tumors of the testis (GCTT) and it has been included in the AJCC staging system. Nevertheless, its histological assessment is challenging, with low/moderate interobserver agreement also among expert uropathologists. Few studies focused on the potential role of immunohistochemistry to solve this critical issue; as result, in current guidelines there is no indication for additional staining to detect this histological feature. In the present study, we investigated the detection of LVI invasion in a small cohort of GCTT with double staining for OCT4/CD34. Although our results need to be validated in larger case series with follow-up data, they suggest as OCT4/CD34 could be a useful tool for the histological assessment of these tumors, helping to identify some histological mimickers of LVI and modifying the pT/stage in a significant percentage of patients.

    Abstract In developing countries, organic waste is commonly dumped in untreated landfills. Brazil has around 3,000 landfills distributed in 1,600 cities. The Brazilian government instituted the National Solid Waste Policy (PNRS), which set the goal of ending the dumping grounds in 2014. However, it was not accomplished. Municipal governments do not have the resources to fund the existing treatment technologies. Thus, there is an urgent need to propose low-cost alternatives to solve this problem. This work proposes a low-cost Product-Service System (PSS) solution that enables the proper treatment of organic waste using the current municipal budget, based on the renting of household biodigesters. It was outlined from a model built on various proposals for the PSS design, published between 2011 and 2018. A feasibility simulation of the proposal conducted for the scenario of the Brazilian city of Porto Amazonas has demonstrated that, by adopting the proposal, the administration could comply with the PNRS and save part of its actual budget. It also showed 75% of probability of financial viability for the PSS provider, in a scenario of reduction of up to 20% in the current municipal costs for organic waste collection and transportation, and up to 40% off in cooking gas costs for the equipment-hosting households. The proposal is a potential solution for the Brazilian municipalities with more favorable scenarios to comply with the PNRS, as well as other countries' municipalities with budget constraints to eliminate their dumps.

    Abstract Anthropocentrism and disciplinary research have not led to effective solutions to sustainability problems. A shift is required towards biocentric, transdisciplinarity-based solutions, to mitigate rebound effects and unintended, negative effects. In the field of Sustainable Supply Network Design, such shift implies on developing resilient solutions that maximize environmental benefits instead of minimizing environmental impacts. Recent researches have showed progress in this direction proposing more integrative approaches, but a framework to design supply networks with the purpose of environmental regeneration is yet to be proposed. This research aims to fill this gap, merging concepts from Regenerative Design, Transdisciplinary Research, Systems Thinking, Social Sciences and Design Sciences. Such framework is regarded as an artefact, and Design Science Research Methodology used for its development: a main problem is identified, objectives for a solution are drawn and the framework is designed. First, the Regenerative Supply Network Design is defined, to guide the elaboration of the Regenerative Supply Chain Design framework, consisting of six steps: (i) description of the network surroundings and identification of a regenerative purpose; (ii) redesign of outputs (iii) network conceptualization, (iv) optimize performance, (v) choose configuration, and (vi) implementation. Among the implications of this research are that (i) practitioners basing their design process in this framework are effectively shifting from anthropocentrism to biocentrism with a clear, defined purpose of environmental restoration and (ii), that the supply networks evolve in the integration with the environment, enhancing eco-systems resilience.

    Abstract Background: Lymphovascular invasion (LVI) is a relevant prognostic factor in germ cell tumors of the testis (GCTT), and it is included in the pT stage. However, its detection on hematoxylin and eosin (H&E) slides is very challenging, and previous studies reported fair to moderate inter-observer agreement among dedicated uropathologists. In the present study, we tested H&E and a recently developed in-house double staining for OCT4/CD34 to detect LVI in GCTT.
    Methods: Nine authors [5 non-uropathologists and 4 uropathologists] independently evaluated 34 consecutive and retrospectively enrolled cases of GCTT. We assessed the inter-observer agreement (Fleiss's Kappa) with both H&E and OCT4/CD34. Besides, we compared the consensus diagnosis on both H&E and OCT4/CD34-stained sections with the original diagnosis to evaluate the pT re-staging (McNemar test) and identify the sources of disagreement.
    Results: The inter-observer agreement among uropathologists plus non-uropathologists was fair with both H&E (KF=0.398; p < 0.001) and OCT4/CD34 (KF=0.312; p < 0.001). OCT4/CD34 (KF=0.290; p < 0.001) slightly reduces the inter-observer agreement compared to H&E (KF=0.321; p < 0.001) for non-uropathologists; in contrast, OCT4/CD34 (KF=0.293; p < 0.001) significantly reduces the inter-observer agreement compared to H&E (KF=0.529; p < 0.001) for uropathologists, changing it from moderate to fair. Consensus diagnosis with H&E modified the LVI status of the original diagnosis in 8/34 (23.5 %) cases (p: 0.070), with pT re-staging in 2/34 (5.9 %) cases (p: 0.500). Consensus diagnosis with OCT4/CD34 modified the LVI status of the original diagnosis in 8/34 (23.5 %) cases (p: 0.289), with pT re-staging in 3/34 (8.8 %) cases (p: 0.250). The consensus diagnosis with OCT4/CD34 modified the consensus diagnosis with H&E in 8/34 (23.5 %) cases (p: 0.727), and these findings resulted in pT-restaging in 3/34 (8.8 %) cases (p: 0.500). The sources of disagreement among uropathologists were: H&E [artefactual clefts misinterpreted as LVI in 4/6 (66.7 %) cases and true foci of LVI misinterpreted as clusters of histiocytes within the vessels in 2/6 (33.3 %) cases], OCT4/CD34 [artefactual clefts misinterpreted as LVI in 2/8 (25 %) cases, true LVI misinterpreted as artefactual clefts in 2/8 (25 %) cases or floaters in 4/8 (50 %) cases].
    Conclusions: OCT4/CD34 does not improve the inter-observer agreement for the assessment of LVI in OCT4(+) GCTT. Consensus diagnosis with H&E modifies the LVI status in a significant number of cases, resulting in changes of the pT stage in a relatively small subgroup. Consensus diagnosis with OCT4/CD34 provides little additional benefit since it cannot exclude mimickers of LVI such as floaters and artefactual clefts. These results argue against the adoption of this diagnostic tool for the routine assessment of OCT4(+) GCTT.

    Abstract Sustainable Supply Chain Design can be performed using optimization strategies for minimizing environmental impacts while maximizing profit. It is not clear how such strategies influence the resilience of a supply chain its ability to cope with disruptions without compromising its function. This research used the Ecosystem Network Analysis (ENA), a model from Ecological Economics, to evaluate the resilience during the design of a sugar beet supply chain. The Ɛ-constraint method was used to solve a multi-objective, mixed-integer linear programming model (MOMILP). Results showed that ENA results are compromised when the strategy of minimizing environmental impacts is used, due to the increased fragility of the configuration, compared with the configuration from the profit maximization strategy. Sensitivity analysis also revealed that, when the number of facilities is increased, ENA results improve while profit is decreased. ENA showed an interesting potential to support the pursuit of balance between resilience and performance, bringing insights during early design stages.

    Abstract Reverse Logistics Networks (RLNs) have grown in importance after return policies became compulsory. Lately, questions have been raised whether they e®ectively decrease environmental impact: e®orts to optimize the eco-e±ciency of RLNs through minimizing costs and emissions were deployed, but results are not advancing with the necessary speed. Alternatively, the eco-e®ectiveness (\doing the right thing" for the environment) approach emerges, promoting a supportive relationship, balancing environment and economy. This research aims to model the design (or redesign) process of eco-e®ective RLNs. There are numerous ecodesign tools focusing on product or service design, but an eco-e®ective designprocess conceived speci¯cally for logistics design purposes is yet to be delivered. Research was carried out using the Design Science Research Methodology and an exempli¯cation for the Poultry Industry was outlined to demonstrate how the process unrolls. The model was conceived using a combination of Upcycling, Industrial Symbiosis, TRIZ rationale and Collaboration for Sustainability. The proposed design process model will help the conception of more innovative, eco-e®ective logistics networks.

    Abstract With the objective to optimize fixed-time artificial insemination (FTAI) protocols based on estradiol benzoate (EB) and progesterone (P4), we performed 2 experiments (Exp.) in dairy cows. In Exp. 1 (n=44), we hypothesized that increased EB (EB3=3 mg vs. EB2=2 mg) on d 0 would improve synchronization of ovarian follicle wave emergence. Likewise, in Exp. 2 (n=82), we hypothesized that a GnRH treatment on d -3 (early in a follicular wave on d 0) versus d -7 (presence of a dominant follicle on d 0) would better synchronize wave emergence. Moreover, results from both experiments were combined to identify reasons for the lack of synchronization. All cows were treated with EB at the time of introduction of a P4 implant (d 0). On d 7, cows were given 25 mg of prostaglandin F2α; on d 8, the implant was removed and cows were given 1mg of estradiol cypionate. All cows received FTAI on d 10. In both experiments, daily ultrasound evaluations were performed and, in Exp. 2, circulating P4 was evaluated during the protocol. Pregnancy per artificial insemination (P/AI) was determined on d 31 and 59 after FTAI. In Exp. 1, EB dose did not change time to wave emergence, but EB3 compared with EB2 decreased the percentage of cows with a corpus luteum on d 7 (19.8 vs. 55.3%) and time to ovulation (10.4 vs. 10.9 d). In Exp. 2, although we detected a tendency for delayed follicle wave emergence after the start of the FTAI protocol in cows ovulating to GnRH given on d -7, there was no difference in percentage of cows with a synchronized wave emergence (~80%). Regardless of treatment, more cows with P4<0.1 ng/mL, compared with P4≥0.1 and <0.22 ng/mL at the time of AI, ovulated to the protocol (81.2 vs. 58.0%) and had increased P/AI (47.4 vs. 21.4%). An analysis of data from both experiments showed that only 73.8% (93/126) of cows had synchronized wave emergence, and only 77.8% (98/126) of cows ovulated at the end of the protocol. Fertility was much greater in cows that had emergence of a new wave synchronized and ovulated to end of the protocol [P/AI 61.3% (46/75)] compared with cows that failed to present one or both of the outcomes above [15.7% (8/51)]. Thus, although current FTAI protocols using EB and P4 produce P/AI between 30 and 40% for lactating dairy cows, there remains room for improvement because less than 60% (75/126) of the cows were correctly synchronized. Starting the FTAI protocol without the dominant follicle or increasing the dose of EB to 3mg was not effective in increasing synchronization rate.
