title: A theoretical framework to adopt collaborative initiatives in supply chains

description: Abstract Collaborative initiatives emerged in the 1980s as a means to increase inter-organizational cooperation, thereby achieving performance improvements in supply chains. Despite this, no consensus exists among researchers with respect to which collaborative initiatives should be deployed along a supply chain. This study analyzes five collaborative initiatives—Quick Response (QR), Efficient Consumer Response (ECR), Continuous Replenishment Program (CRP), Vendor Managed Inventory (VMI) and Collaborative Planning, Forecasting and Replenishment (CPFR)—by conducting a systematic literature review, aiming to develop a theoretical framework to guide the decision-making process of adopting and implementing these initiatives. Based on the characteristics of the collaborative initiatives, expected benefits, reasons for adopting, and possible barriers found in the literature review, a theoretical framework was developed as a flowchart, clearly indicating to decision-makers the main aspects of concern when adopting one or more collaborative initiatives and highlighting the need to constantly monitor the chosen initiative’s performance.

title: Does resilience influence food waste causes? A systematic literature review

description: Abstract Studies that seek to relate resilience and food waste are still at an early stage. For organizations to be prepared to avoid and/or reduce it to improve their operations it is necessary to understand the impact of resilience on the food waste reduction. The aim of this article is to identify how elements of resilience can influence the causes of food waste in retail. To that end, we conducted a systematic literature review, which resulted in 90 articles. Next, we conducted a content analysis to facilitate a rigorous exploration of complex issues in the management field, seeking to relate the elements of resilience to the causes of food waste. We imported the articles into the QDA Miner qualitative data analysis software and then separated phrases and texts following the codebook guidelines. It was possible to locate common properties to the articles and to make initial comparisons between the resilience and food waste causes. As a result, it was observed that the elements of resilience can positively or negatively influence the causes of food waste in the retail and that most of these elements are related to the anticipation. The main elements of resilience identified are: Flexibility, Visibility and Collaboration. However, this influence is partial, since some of the elements, such as Redundancy and Financial Strength, prevent the full implementation of waste reduction. Finally, we discuss the study’s limitations and opportunities for further development in the conclusion.

title: Perceptions about the media and behaviour when buying food products: case study with consumers from two cities in the south of Minas Gerais State

description: Abstract Media and food advertisements today represent important industrial strategies for the differentiation, promotion and selling of products. Thus, they can exert a strong influence on consumer buying and consumption behaviour. Considering this, the objective of this work was to evaluate the perception of consumers about the media and its influence on food purchasing behaviour through a market research survey with consumers from two municipalities in the south of Minas Gerais State, Brazil. A non-probabilistic sample was used for convenience, totalizing 285 respondents (150 in Varginha and 135 in Lavras), and an interview with questions prepared by the researchers themselves being used as the research instrument. The data were analysed in a descriptive way. Based on the results, it could be seen that, for the sample under study, food consumption could be influenced by the media and by the food advertisements. Exposure to these ads may also be related to opinions about what is most valued in the purchase of food, such as practicality and convenience. Regarding the reading of labels, a low frequency of consumers who frequently read this information was observed. Together, these results reinforce the evidence that marketing strategies have the potential to influence the eating behaviour of the subjects, and, therefore, also contribute to the achievement of public health goals for food and nutrition. In this case, the importance of food and nutritional education strategies for the training of more autonomous and critical consumers regarding their food choices is highlighted.

title: Microstructural Evolution Due to One Thermal Cycle in a Superduplex Stainless Steel ASTM A890/A890M - Grade 6A in the As-Weld and Post-Weld Heat Treatment Conditions

description: During welding of the superduplex stainless steels are exposed to thermal cycles, allowing precipitation of deleterious phases as well as unbalance as the ferrite and austenite phases. This work analyzed the microstructural changes taking place on a plate ASTM A890/A890M - grade 6A steel submitted to arc welding one welding of pass conducted on a flat surface using coated electrode Zeron®100, in the as welded and post-welded heat treatment conditions. Microstructural characterization in the regions base metal, heat affected zone, and fusion zone were conducted by optical microscopy, scanning electron microscopy and X-ray diffraction. The post-weld heat treatment in the fusion zone changed the ferrite/austenite volumetric fraction from 59/41 to 52/48. Cr, Mo and Ni distributions in the fusion zone were altered after the post-weld heat treatment, with the concentration ratio ferrite/austenite being around 1.0; 1.1 and 0.9 to 1.1; 1.4 and 0.7, respectively. In addition, hardness reduced from 300 to 270 HV0.3 at the fusion zone.

title: Left Atrial Size Contribution to the Predictive Capacity of Two Scores for Atrial Fibrillation in the Postoperative Period of Cardiac Surgeries

description: Abstract Background: Postoperative atrial fibrillation (POAF) is a common complication associated with undesirable outcomes; hence, the provision of appropriate tools is important to help identify patients at risk. Objectives: To evaluate the predictive capacity of the CHADS2 and CHA2DS2-VASc scores, alone and combined with left atrial (LA) size, for the onset of POAF in patients undergoing coronary artery bypass grafting and/or valvular surgery. Methods: We performed a retrospective cohort study on 144 patients. A decision tree was used to identify the cut-off values of the CHADS2 and CHA2DS2-VASc scores and LA size in order to calculate sensitivity, specificity, predictive-value positive (PVP), and predictive-value negative (PVN), in addition to regression models. The receiver operating characteristic (ROC) curve was used to estimate the accuracy of the models. The level of significance adopted was 5%. Results: Patients who developed POAF were older (p = 0.050), had reduced left ventricular ejection fraction (p = 0.045), longer hospital length of stay (p = 0,018), but their mean CHADS2 (p = 0.077) and CHA2DS2-VASc (p = 0.109) scores were similar to those of patients with no arrhythmia. LA size improved the predictive capacity of the CHADS2 score, in terms of specificity and PVP, and of the CHA2DS2-VASc score, in terms of sensitivity and PVN. However, the CHADS2 (OR = 1.198; CI95% = 0.859-1.156) and CHA2DS2-VASc (OR = 1.047; CI95% = 0.784-1.401) scores were not predictors of POAF, either alone or in combination with LA size (OR = 1.163; CI95% = 0.829-1.648 and OR = 1.065; CI95% = 0.795-1.433). Conclusion: The CHADS2 and CHA2DS2-VASc scores alone or in combination with LA size did not show good predictive capacity for POAF.

title: EXPERIMENT OF A SWING SEPARATING SIEVE ON A POTATO DIGGER

description: ABSTRACT For the purpose of achieving the distribution of the potato-soil mixture and the appropriate parameters of the swing separating sieve, we conducted experiments using the 4SW-170 potato digger. The experiments consisted of two parts. In each part, the experimental factors were crank rotational speed, sieve inclination and machine forward speed. The difference is that the first part involved a single factor test, which selected the coverage of the potato-soil mixture as the evaluation indicator. In contrast, the second part involved an orthogonal test, which selected the obvious rate and damage rate as evaluation indexes. In the first part, it was observed that the coverage of the potato-soil mixture on the separating sieve reduced gradually with the increase in crank rotational speed and sieve inclination. Inversely, as the machine forward speed was raised, the coverage of the potato-soil mixture gradually increased. In the second part, when the crank rotational speed was 230 rpm, the sieve inclination became 21.1°, and the machine forward speed was 2.03 km . h-1; the optimal parameter combination was obtained. Under such conditions, the obvious rate of potato harvest could reach as high as 99.49%, and the damage rate of potato harvest could reach as low as 0.87%. The reported results may be of help in providing a reference for the design of the swing separating sieve on potato diggers.

title: Model improvement for estimating of water turbidity removal efficiency in helical tubular flocculators

description: ABSTRACT Scientific studies have been demonstrating that helical tubular flocculators (HTFs) have high efficiency in floc formation and low hydraulic retention time when compared to flocculators commonly used in water and wastewater treatment. However, its practical application is still limited because there is still a significant demand for advances in the understanding of the relationship between the hydrodynamics of the unit and the flocculation process, as well as for criteria and methodologies in support to the rational design of HTF. In this context, the objective of this study was to propose an improvement in the model of turbidity removal efficiency developed by Oliveira (2014), which takes into account a set of geometric, hydraulic and hydrodynamic parameters relevant to the flocculation process in this type of reactor, by incorporating one of the most representative parameters of flocculation processes, the normal pressure gradient, as one of its independent variables. The development of the work employs computational fluid dynamics (CFD) in the study of 84 HTFs configurations, considering laminar and turbulent flow regimes. As a result, a new model version for estimating water turbidity removal’s efficiency in helical tubular flocculators was obtained, which, in relation to the original version, has a smaller number of independent variables, presents better fit to the experimental data and is simpler from the operational point of view.

title: Soil physical and hydraulic properties in the Donato stream basin, RS, Brazil. Part 1: Spatial variability

description: ABSTRACT The processes of water flow and water storage in the soil are directly associated with its hydraulic properties, which may vary significantly in space. Therefore, this study aimed to perform a spatial analysis of saturated hydraulic conductivity and the parameters of the soil water retention curve in the Donato basin, located in the municipality of Pejuçara, in the northwest region of the state of Rio Grande do Sul, Brazil, with geographic coordinates between 28º 25’ 34” S and 53º 40’ 30” W, and 28º 24’ 50” S and 53º 41’ 30” W, 590 m of altitude. Undisturbed soil samples (total of 55) were collected from August to November of 2012. The results have demonstrated larger variability for hydraulic conductivity and for the parameter α of the retention curve, and allowed identifying that the high spatial heterogeneity of the studied variables could be associated with factors such as climate, land use and land cover, sampling errors, sampling grid density and also the level of soil compaction.
