GResilient index to assess the greenness and resilience of the automotive supply chain
Purpose: The purpose of this paper is to suggest an Index entitled GResilient Index to assess the greenness and resilience of the automotive companies and corresponding supply chain. Design/methodology/approach: An integrated assessment model is proposed based on Green and Resilient practices. These practices are weighted according to their importance to the automotive supply chain competitiveness. The Delphi technique is used to obtain the weights for the focused supply chain paradigms and corresponding practices. The model is then tested using a case study approach in the automotive supply chain. Findings: The case study results confirmed the applicability of this Index in a real-world supply chain. The results show that the Resilient supply chain management paradigm is the one considered as the one that more contributes for the automotive supply chain competitiveness. Research limitations/implications: The proposed Index was developed in the automotive sector context therefore it could not be adjusted to a different one. Future research could consider other aggregation methods for the Index construction. Practical implications: Supply chain participants will be able to evaluate the performance of their companies or supply chain in terms of Green and Resilient paradigms. Also, the Index can be effectively employed for functional benchmarking among competing companies and supply chains.Green; resilient; supply chain management; index; automotive industry
Supply chain disturbances and resilience strategies: a secondary data study
This research is funded by Fundação para a CiĂȘncia e Tecnologia (project MIT-Pt/EDAM-IASC/0033/2008 and project PTDC/EME-GIN/68400/2006). The principal author was supported by a PhD fellowship from Fundação para a CiĂȘncia e Tecnologia (SFRH/BD/43984/2008).This paper is a review over a variety of events which lead to disruption conditions in supply chains and identifies correspondent resilient strategies for each condition. The paper objective is to make a link between the problems created by events and strategies that managers can use to avoid or mitigate the negative aspects of those problems and improve post-event recovery. To attain the paper objectives, archived media news were used to collect empirical data about disturbances (events), their negative effects (problems), and resilience strategies. In the data collection phase, the aim was to keep diversities and be comprehensive. Using empirical evidences from the sample is developed a graph to show the links between supply chain disturbances, problems and resilience. This research provides supply chain managers with some alternative strategies to opt for the best available decision, improving the post-event management process.publishersversionpublishe

Development of cellulose acetate membranes containing nanoparticles for water applications
The growth of human population and inherent activities, the improper industrialization practices, the direct
addition of materials TO the waterway, and the excessive use of fertilizers containing phosphates to increase
the production of crops are the main sources for the high input of phosphates in water bodies. These effects
have been causing eutrophication, and bacterial contamination of the water. In fact, the bacteria present in the
water can cause harmful disease, sickness or other problems to the human being. Moreover, the excess of
phosphates in the aquatic system induces excessive growth of plants, which consume oxygen of the water
body, thereby creating the state of hypoxia, which causes a reduction in specific fish and other animals.
Therefore, the removal of phosphates from eutrophic waters and bacteria are crucial to avoid health problems,
especially near urban areas[1].
The most common way to purify water is through membrane separation processes, in fact, cellulose acetate
(CA) membranes have been used for reverse osmosis membranes [2] for converting impaired water into
fresh-water. However, several components can be incorporated into cellulose structure to allow the
development of membranes for different applications[3].
The present work aims to develop a hybrid membrane based on CA with embedded silver and/or aluminium
nanoparticles, for the remediation of contaminated aquatic environments with microorganism, which can also
be used for removal of water contaminated with phosphate ion. Therefore, CA membranes were obtained by
solution casting, where silver and/or aluminium nanoparticles were chemical reduced in-situ. Silver
nanoparticles (Ag-NPs) were synthesized using silver nitrate and sodium borohydride as reducing agent.
Otherwise, aluminium nanoparticles (Al-NPs) were obtained using aluminium isopropoxide as the starting
precursor in the presence of acid.
The detection of Al-NPs in the membranes was carried out by FTIR spectra analysis, which showed that Al-O
bonds were formed between the aluminium precursor and the CA. The study of phosphorus adsorption kinetics
in membranes with embedded Al-NPs were proven to be efficient for the removal of phosphorus. This
membrane showed considerable ability to remove phosphate ions from aqueous solutions at low aluminium
nanoparticle content into the CA/Ag-NPs matrices. In-situ the developed membranes showed good
antimicrobial behaviour preventing the growth of microorganisms. The results indicate that the synthesized
CA/Ag-NPs/Al-NPs membranes could have potential to be used in the remediation of water resources
EVIDĂNCIAS DE INFLAMAĂĂO DAS VIAS AĂREAS RESPIRATĂRIAS INFERIORES, EM POTROS PSI SAUDĂVEIS, ANTES DO INĂCIO DOS TREINAMENTOS
ObstruçÔes do trato respiratĂłrio inferiorapresentam grande impacto no potencial atlĂ©tico decavalos de corrida. Doença InflamatĂłria das ViasAĂ©reas (DIVA) constitui achado comum em cavalosde corrida jovens. Esse estudo testou a hipĂłtesede que a inflamação do trato respiratĂłrio inferiorpoderia iniciar ainda na vida no haras. Sete diferentesharas foram visitados, e 119 potros sobreanoforam investigados. As vias aĂ©reas inferiores foramavaliadas atravĂ©s de exame clĂnico e endoscĂłpico,e citologia do aspirado traqueal. Entre os potrosconsiderados clinicamente saudĂĄveis, 90,76% evidenciarammuco traqueo-bronquial e os perfis citolĂłgicosevidenciaram reação inflamatĂłria presente.A presente investigação confirma a presença deinflamação pulmonar em potros PSI antes do inĂciodo treinamento, representando um risco potencial Ă capacidade atlĂ©tica futura.Lower respiratory airway obstruction has a major impact in racehorse athletic potential. Inflammatory Airway Disease (IAD) is a common finding in young racehorses. This study tested the hypothesis that lower airway inflammation could initiate in farm life. Seven different breeding farms were visited, and 119 yearlings were investigated. Lower airways were evaluated by clinical examination, endoscopy and cytology of the tracheal aspirate. From those yearlings considered clinically healthy, 90,76% evidenced tracheobronchial mucus and some showing cytological profile of inflammatory reaction. Then, the present investigation confirms the occurrence of inflammatory condition of the lower respiratory airways in thoroughbred yearlings before training has commenced, representing a potential risk for the future athletic performance in young racehorses
The influence of eco-innovation supply chain practices on business eco-efficiency
This paper aims to study the influence of eco-innovation practices on eco-efficiency of business, which embraces environmental and economic performance. Four hypotheses are drawn up based on the existing literature in green supply chain and considering the business innovation. A survey questionnaire was used to collect data on a sample of USA and Portuguese innovative organizations. Multivariate statistics and Partial Least Squares (PLS) path modelling techniques were used to test the proposed hypothesis.
The statistical analysis allows to conclude that there are differences between the eco-innovation practices deployed by organizations belonging to different sectors and with different sizes. Also, it was found that the level of implementation of the different eco-innovation practices by organizations influence the eco-efficiency of businesses
