5. How the sorption of benzene in soils contaminated with aromatic hydrocarbons is affected by the presence of biofuels - Maria Manuela Carvalho; Maria Cristina Vila; Fernanda Rohden; Mónica Silva; Joana Dias; Teresa Oliva-Teles; Anthony Danko; Cristina Delerue-Matos; António Fiúza
The increasing use of biofuels as additives to gasoline may have potential indirect effects on the efficiency of soil remediation technologies used to remediate fuel spills. This problem has not yet been studied. Sorption is one of the controlling processes in soil remediation. The effect of biofuels on sorption and phase distribution of contaminants by different natural soils has not been reported on the literature. The present work examines how two different biofuels, n-butanol and soybean biodiesel, affect benzene sorption in two naturally occurring subsoils (granite and limestone). Sorption isotherms were made with soils deliberately contaminated with benzene, benzene and...

8. Scientists and the 3Rs: attitudes to animal use in biomedical research and the effect of mandatory training in laboratory animal science - Franco, Nuno H.; Olsson, I. Anna S.
The 3Rs principle of replacement, reduction, and refinement has increasingly been endorsed by legislators and regulatory bodies as the best approach to tackle the ethical dilemma presented by animal experimentation in which the potential benefits for humans stand against the costs borne by the animals. Even when animal use is tightly regulated and supervised, the individual researcher’s responsibility is still decisive in the implementation of the 3Rs. Training in laboratory animal science (LAS) aims to raise researchers’ awareness and increase their knowledge, but its effect on scientists’ attitudes and practice has not so far been systematically assessed. Participants (n=206) in...

13. A hybrid VNS approach for the short-term production planning and scheduling: A case study in the pulp and paper industry - figueira, g; santos, mo; almada-lobo, b
Mathematical formulations for production planning are increasing complexity, in order to improve their realism. In short-term planning, the desirable level of detail is particularly high. Exact solvers fail to generate good quality solutions for those complex models on medium- and large-sized instances within feasible time. Motivated by a real-world case study in the pulp and paper industry, this paper provides an efficient solution method to tackle the short-term production planning and scheduling in an integrated mill. Decisions on the paper machine setup pattern and on the production rate of the pulp digester (which is constrained to a maximum variation) complicate...

19. Retrospective evaluation of therapeutic outcomes of functional appliances combined with headgear - José Pedro Tavares; Afonso Pinhão Ferreira; Paula Vaz; Maria João Ponces; Eugénio Joaquim Pereira Martins
Functional appliances were developed to correct mainly Class II malocclusions in growing children but the influence of those appliances on craniofacial growth is still controversial, even when used in combinations with headgear. The aim of this retrospective study was to investigate skeletal, dental and tegumental cephalometric modifications induced by Teuscher activator. This study was accomplished in a mixed dentition sample of Class II malocclusions subjects with mandibular retrognatism. This appliance was effective in treating growing patients with mandibular deficiency: the correction of Class II malocclusions was an arrangement of skeletal and dentoalveolar changes and leaded to the improvement of soft...
