The Circular Economy is driven by sustainable strategies of management and the reuse of materials and power to try to decrease the demand of resources and minimize the environmental impacts. Aligned to said perspective, the Industrial Symbiosis (IS) is opposite to the linear production's logic, enabling the sharing of resources, waste, and by-products, that is, the circular flow of power, water, materials, and information. In the last few years, to improve these IS strategies, platforms and tools were created to intermediate this process and facilitate the match between those who demand and offer waste and resources, such as the online waste markets or e-marketplaces. From this perspective, the objective of this study is to evaluate how these tools contributed to the IS process, going beyond the problem of the local factor. For this purpose, ten online platforms, found in the literature, were selected. The analysis was made based on the identification of key elements, which enabled the creation of a list with different types of traded materials, sectors and areas served, how wide was the service, the year when the activities started and, ultimately, the business model adopted. As a result, the evaluation shows that these tools enhance the symbiosis process because they approach the parties and facilitate the identification of synergies. Generally, the use of online platforms widens the geographic scope of the IS processes, enabling the interaction of parties from different places and regions. Was observed that these tools are characterized by the use of intelligent systems, based on algorithms that identify and recommend relations, providing greater assertiveness and speed to the decision-making process. Among the research's findings, we must stress that the IS potential extends much beyond the reuse of waste. There are opportunities for other synergies, such as infrastructure and service sharing. Finally, it was highlighted that, although they present many benefits

Surviving and growing in a world characterized by competitiviness in a global scale and by continued and unexpected changes, has been a paradigm for the organizations. With the globalization process, which is a reality, the technological evolution and the complexity of the modern world, new needs have appeared in the working position realm, The concrete fact is that transformations alter the work-man, man-machine, man-productive system relations besides the kinds of workers. The man-machine relation is really important in the organizational environment because the technological advances may motivate the worker as well as scare and unqualify him. So, no ergonomics analysis through working signs may be an excellent tool to help in the adaptation of the worker to the working position and also detect and settle the points which must be emphasized and modified to obtain the organizational efficiency.

Cleaner production Letters 2022年 3卷

Business models and investors should understand the meaning of ‘value’ from a different perspective if the ultimate goal is to achieve the sustainable development goals (SDGs). New business strategies for pursuing the SDGs and the aptitude to set up cleaner and more collaborative production systems must replace the traditional approaches tied to a value perception that is not coherent with the actual sustainability performance of companies. This outdated but still largely used value perception is often vague, abstract, and lacks more objective models and indicators to avoid misleading choices of investments in companies with low levels of sustainability. Using a mining company in Brazil as an example, this commentary letter aims to provide insights about the need for information rooted in science, considering biophysical perspectives under a systemic approach to fully understand the meaning of value behind companies' performance and support investments in those more sustainable ones. Parameters to quantitatively assess companies' sustainability are presented to start the discussions about how investors can make better choices when putting their money on those really more sustainable companies that, besides returning profits, will support the achievement of SDGs. © 2022 The Authors

The ordinal methods are widely used to establish rankings in sports competitions because sporting results are on an ordinal scale. However, these methods assume that the decision maker is highly rational and provide a full ranking. This paper analyses the case in which the decision maker is weakly rational. In this case, the decision maker respects the transitivity of preferences but not indifference. It also shows how to adapt the Condorcet method to deal with this situation, using the results of the 2013 Formula 1 Constructors’ World Championship.

Laser Metal Deposition (LMD) process is an additive manufacturing technique that has attracted the interest of the automotive and aerospace industries due to its ability to manufacture parts with complex geometries and different types of metallic materials. However, the structure of the deposited layers and the geometrical characteristics of the manufactured parts are influenced by the interaction among the deposition process parameters. In this paper, fuzzy inference (FIS) technique was used to develop two models for predicting the geometrical characteristics and, for optimizing the LMD process parameters using AISI 316 stainless steel powder and substrate. An experimental design, based on factorial analysis, was used to correlate the influence of selected deposition process parameters, laser power (Lp), powder flow (Pf) and focal length (Fl) with the process geometrical characteristics bead height (Bh), bead width (Bw), depth of penetration (Dp), dilution (d) and wetting angle (wa). The factors Lp and Fl were used with three operating levels each: Lp = 225 W, 250 W, 275 W, and Fl = 4.8 mm, 5.0 mm, 5.2 mm. The factor Pf was used with two levels, 9.40 g/s and 13.35 g/s. Analysis of variance allowed identifying that the Pf affect the Bh, Bh/Bw ratio, d and wa. The increase in Laser power (Lp) resulted in an increase of the geometric characteristics Bw and Dp. The first FIS, for predicting the bead’s geometrical characteristics, presented high adequacy (relative error up to 8.43 %) for assessing the experimental conditions. The second FIS indicated the best possible interaction, given the studied operating conditions and the variables evaluated. The maximum Output Defuzzified Index (ODI = 0.845) was obtained with the deposition process parameters Lp = 250 W, Fl = 5 mm, and Pf = 9.40 g/s. © 2021, CC BY.

Corporate Venture Capital (CVC) has been receiving increasingly more attention all over the world as a special way for accessing new ideas and innovative opportunities through minor-share investing in established companies. The purpose of CVC investments may either be purely financial or to pursue strategic goals. Organisations often seek to take actions that impact positively on sustainability by assembling related knowledge and technologies. These resources may come from invested startups through the use of a CVC programme. This research aims to measure and analyse the Corporate Venture Capital programmes of companies listed in the ISE B3 Corporate Sustainability Index. To this end, a three-step methodology was conducted. First, a systematic review of the literature took place, followed by a review of companies based on secondary sources such as their websites. Finally, a survey was developed and was opted to survey companies through their Investor Relationship (IR) public channels. Results show that 27 of the companies listed in the ISE B3 Index have CVC programmes that contemplate organizational initiatives besides investment. In this sense, one can claim that at least 70% of the ISE B3 Index companies are somehow involved in CVC operations. The results contribute to the literature on corporate venture capital and sustainability by showing that companies spend from 10% to 15% of their capital in sustainable businesses in order to remain competitive. © 2022 by the authors.

Economic globalization and population growth have greatly challenged energy, water and land resources to meet demand at national and supra-national level. A growing share of this demand is met through trade. The Belt and Road, a major global initiative of China, with trade as one of its core fields is of particular importance due to greater potential of economic growth, substantial population size and varying degree of resource availability. The initiative reflects a new phase of globalization yet resources management with nexus thinking has received little attention. The increasing economic interdependence of national economies have contributed to rise in production and trade of goods and services, these activities require the input of energy-water-land and generate disturbances in the environment. The multi-regional input-output approach is utilized, to assess resources use by production as well as consumption (for the year 2010). A nexus strength indicator was developed to show the simultaneous use of multiple resources in economic system, conceived as resource nexus. The ternary diagrams were used for screening resources combinations along with *** revealed that China has strong nexus strength that indicates large usage of the three resources together. Besides China, the East European countries were also positioned mostly at the center of ternary plot suggesting somewhat equal contributions of energy, water and land to the resource nexus. On the contrary, countries that appeared at the margins of the plot indicated one or two stronger nexus components in the three resources system. For instance, Russia largely used land, South Korea was entirely driven by energy while India mostly used water in the ternary mix. Due to differences in industrial structure, trade policy priorities and technology use, the resource nexus matters are not the same among countries. The nexus strength indicator established that strong nexus caused by intensive use of e

Among the wide range of applications of Cobalt Ferrite (CoFe2O4), its usage for the manufacturing of modern electronic devices such as solar panels, capacitors and batteries has been studied' lately. Hence, solar-powered vehicles, which strongly rely their performance on energy efficient electronics, is a sector that could particularly benefit from enhanced applications of such material. In this work, the synthesis of Cobalt Ferrite was studied by means of Solution Combustion Synthesis (SCS) using iron nitrate nonahydrate and cobalt nitrate hexahydrate as precursors, and glycine as fuel. The nitrates were dissolved in distilled water and placed under stirring and heating for 5 minutes; when the temperature reached 60°C, glycine was added; after complete homogenization, the solution was placed in an electric oven (400°C) until complete combustion (approximately 15 minutes). Three syntheses were carried out using different concentrations of fuel: lean, stoichiometric and rich. The product crystallite size and composition were investigated in order to determine the influence of the fuel concentration on the structure of the produced cobalt ferrite.

Objective Antimicrobials are used interchangeably in medical practice, contributing to the emergence of resistant microbial strains. Methods This study describes the antimicrobial audit performed by forecasting analysis of medical records of 846 patients at the Hospital Santa Cruz, Santa Cruz do Sul - Rio Grande do Sul - Brazil. Results Of the patients studied, 134 (15.8%) received antimicrobials. The audit was conducted interactively, with intervention and discussion with the prescriber. Considering the presumptive diagnosis and prescribed drug, it was verified that 74.6% of patients on antimicrobials received what was considered the first choice treatment. Inadequate antimicrobial agent for clinical diagnosis (5.2%) and lack of adjustment for renal function (43.7%) were the most frequent errors. Conclusion A strategic plan aimed at the rational use of antimicrobials based on educational and interventionist practices can help the infection control professional to adjust the routines to improve healthcare quality.
