Sixteen different metazoan parasites were found (14 from Madeira, 9 from Sesimbra and 7 from the azores). Some parasites occurred only in fish from Madeira. the prevalence and mean intensity of the infection was recorded for each parasite and locality, and their values were statistically compared between the three sampling localities and related to host length classes. the differences between some of these parameters were statistically significant among the three localities or between two of them. it is suggested that 6 parasites (Tentacularia coryphaenae, Sphyriocephalus tergestinus, Campbelliella heteropoeciloacantha, Anisakis spp., Bolbosoma vasculosum and unidentified acanthocephala larvae) can be used as biological tags to discriminate Portuguese stocks of Aphanopus carbo.Keywords: parasites, biological tags, Aphanopus carbo, fish, Portugal. reSuMen: Uso de parásitos como marcadores biológicos en la identificación de stocks de sable negro, AphAnopus cArbo Lowe, 1839 (Osteichthyes: Trichiuridae) en aguas portuguesas. -Se estudió el uso de parásitos como marcadores biológicos para discriminar los stocks de Aphanopus carbo (osteichthyes, trichiuridae) de Portugal (Sesimbra en el continente, Madeira y azores islas). dieciséis parásitos metazoarios fueron encontrados (14 en Madeira, 9 en Sesimbra y 7 en azores). algunos parásitos se presentaron sólo en Madeira. la prevalencia y la intensidad media de las infecciones fueron calculadas para cada parásito y cada región, y sus valores fueron comparados estadísticamente entre los tres lugares de muestreo, y relacionados con la talla del huésped. Se encontraron diferencias estadísticamente significativas entre algunos de estos parámetros de las tres regiones o entre dos de ellas. Se sugiere que 6 parásitos (Tentacularia coryphaenae, Sphyriocephalus tergestinus, Campbelliella heteropoeciloacantha, Anisakis spp., Bolbosoma vasculosum y larvas no identificadas de acanthocephala) pueden ser usados como marcadores biológicos para discriminación de stocks de Aphanopus carbo de Portugal.

PurposeThis paper proposes a decision support model that can be used to help decide the destination of defective products, for mass production industries. The objective of this model is to reduce the cost of the defect, and consequently reduce the total quality costs.Design/methodology/approachThe decision model was developed based on the theory of quality costs and decision-making models, considering the practical aspects of reality through data collection, observation and experience in Industrial Pole of Manaus (Brazil) industries. A decision model adjusted to reality assists in the construction of the decision process, indicating the facts, data collection and the planning of the actions to choose the best alternative.FindingsThe specific contributions of this research are: (1) define a sequential structure of actions, effects and costs associated with defective items; (2) allow a comprehensive approach to failure costs, including various elements of lost opportunity costs; (3) minimize failure costs, and consequently reduce total quality costs, without necessarily investing in prevention and assessment; (4) describe the use and application of the built theory; (5) identify the quality cost elements most representative in existence of defective items; and (6) identify improvement points in the management of possible future defective items.Originality/valueMuch of the work of implementation of quality cost models do not emphasize the analysis of the destination of defective items. Also, there are no studies that use decision models with identification, accounting and evaluation of effects and criteria of quality, productivity and cost to define the destination of manufacture defective items.

Anomalies on road pavement cause discomfort to drivers and passengers, and may cause mechanical failure or even accidents. Governments spend millions of Euros every year on road maintenance, often causing traffic jams and congestion on urban roads on a daily basis. This paper analyses the difference between the deployment of a road anomalies detection and identification system in a “conditioned” and a real world setup, where the system performed worse compared to the “conditioned” setup. It also presents a system performance analysis based on the analysis of the training data sets; on the analysis of the attributes complexity, through the application of PCA techniques; and on the analysis of the attributes in the context of each anomaly type, using acceleration standard deviation attributes to observe how different anomalies classes are distributed in the Cartesian coordinates system. Overall, in this paper, we describe the main insights on road anomalies detection challenges to support the design and deployment of a new iteration of our system towards the deployment of a road anomaly detection service to provide information about roads condition to drivers and government entities.
