1. Analyzing complexities in the Brazilian soybean supply chain: a systems thinking and modeling approach
Abstract Purpose This study aims to analyze the complexities of the Brazilian soybean supply chain (SSC) and develop strategic interventions to improve the origin system’s performance. Design/methodology/approach This study used stakeholder interviews to identify the SSC bottlenecks and determine and assess drivers of competitiveness. A methodological fr

2. Fuzzy Modelling to Describe the Pollutant Concentration in Fluids
ABSTRACT The study of the concentration dynamics of a pollutant substance in a fluid is a classic problem of fluid mechanics given by the transport equation u t + cu x = 0, where u = u(x,t) denotes the pollutant concentration along a horizontal pipe of a fixed cross-section in the positive x direction at he time t > 0 and c represents the fluid propagation

3. The electric boat charging problem
Abstract Paper aims This paper studies a new optimization problem called the Electric Boat Charging Problem (EBCP), which is based on the application of electric mobility in a river transport operation problem. Originality This work pioneers the studies of the electric mobility on the river operations, by proposing the EBCP. This problem includes real feat

5. GROWTH AND PHOTOSYNTHETIC EFFICIENCY OF Atriplex nummularia UNDER DIFFERENT SOIL MOISTURE AND SALINE TAILINGS
RESUMO O descarte do rejeito dos dessanilizadores é um problema crescente sobretudo nas regiões semiáridas, sendo necessário o estudo de plantas halófitas como a Atriplex nummularia para o reuso dessas águas salinas. Dessa forma, objetivou-se avaliar o efeito da interação entre níveis de teor de água solo e de salinidade da água de irrigação, na

6. Water acidification causes death of marine ornamental fish (Perciformes: Pomacentridae) during transport: contributing to the conservation of wild populations
ABSTRACT Pomacentridae is a common family in the aquarium fish trade. Most species are harvested from nature. Here we evaluate the following water parameters in the pomacentrid sergeant major, Abudefduf saxatilis (Linnaeus, 1758), to assess their stress level during a 24, 48, and 72 hours transport: dissolved oxygen (DO), total ammonia, and pH. In addition,

7. Mine fleet cost evaluation - Dijkstra's optimized path
Abstract The transport distance in a mining operation strongly influences a mine operation revenue and its operational cycle because it is a fundamental part of the total mining costs. Generally, the transport route is determined based on an engineer's practical knowledge, which does not consider any mechanism to optimize the possible routes to be taken. In

9. MODELOS FOTOQUÍMICOS SIMPLES COMO FERRAMENTA PARA O GERENCIAMENTO DA QUALIDADE DO AR
Atmospheric processes in an urban scenario are very complex and depend on meteorological parameters, emission, transport and deposition processes and the chemical mechanism. Simple air quality models can be used to understand the main aspects of ozone formation and provide information to adopt pollution control strategies. In this work the detailed simulatio

10. SOA-BD: Service Oriented Architecture for Biomedical Devices
Introduction: The communication of information systems with biomedical devices has become complex not only due to the existence of several private communication protocols, but also to the immutable way that software is embedded into these devices. In this sense, this paper proposes a service-oriented architecture to access biomedical devices as a way to abst

11. A mixed integer programming approach for freight railcar distribution
Abstract The attendance of the demand for freight transport is related to the process of allocation of the wagons that in turn is associated with the way in which the decision is taken. The distribution of wagons to the shipment terminals depends on the planning as well as on movement of the empty wagons. In addition, the trips of the empty wagons have the m

12. Dealing with iron metabolism in rice: from breeding for stress tolerance to biofortification
Abstract Iron is a well-known metal. Used by humankind since ancient times in many different ways, this element is present in all living organisms, where, unfortunately, it represents a two-way problem. Being an essential block in the composition of different proteins and metabolic pathways, iron is a vital component for animals and plants. That is why iron
