Cultura e turismo criativo na experiência integral do turismo rural
Carvalho, Mariana Sousa e Silva Cabral deA presente investigação visa, a partir de uma perspetiva cultural, compreender os benefícios do turismo criativo no contexto da experiência turística integral, como forma de aprofundar e aprimorar a qualidade dessa experiência, numa aldeia do Interior de Portugal, Janeiro de Cima (concelho do Fundão). Este estudo, realizado no âmbito do Projeto de Investigação Científica intitulado “A experiência global em turi...
The Biotransformation of Pentachlorophenol by Mucor plumbeus: Mechanistic Insights
Carvalho, Mariana Boavida LopesDissertation presented to obtain the Ph.D degree in Biochemistry ; Pentachlorophenol (PCP) is a synthetic compound introduced as a wood preservative and used for decades in agricultural and industrial applications. Today, the production and use of PCP is restricted due to its toxicity and environmental impact. However, extensive use in the past and its environmental persistence has resulted in substantial cont...
Maintenance costs of a pitch control device of a wind turbine
Carvalho, Mariana; Nunes, Eusébio P.; Telhada, JoséAlthough the wind turbines are nowadays the principal source of wind energy production, the technical information publicly known about these machines is still very scarce. Information related to failure modes, unavailability and maintenance costs of these systems remain confidential and only the manufacturer has knowledge about them. To be able to optimize the efficiency, to guarantee the security and to negoti...

Maintenance decision making
Carvalho, Mariana Teixeira Baptista de; Nunes, Eusébio P.; Telhada, JoséIn any management process, decision making assumes a very important dimension. Complex systems are commonly fed with large amounts of data that are quickly made available to experts and industrial engineers who, in most cases, are not provided with adequate decision support tools. Therefore, the quality of their decisions heavily relies on their our quality and experience, making the complex systems management ...
RAM factors in the operation and maintenance phase of wind turbines
Cajazeira, Carolina Leite Barbosa; Nunes, Eusébio P.; Telhada, José; Carvalho, Mariana Teixeira Baptista deThe high complexity of technological systems and the increasing requirement and competitiveness of markets request the implementation of adequate management strategies for these systems in order to improve their availability and productivity. In this context, RAM factors constitute a strategic approach for integrating reliability, availability and maintainability, by using methods, tools and engineering techniq...
Non-coding RNAs in schistosomes: an unexplored world
Oliveira,Katia C; Carvalho,Mariana L. P; Maracaja-Coutinho,Vinicius; Kitajima,João P; Verjovski-Almeida,SergioNon-coding RNAs (ncRNAs) were recently given much higher attention due to technical advances in sequencing which expanded the characterization of transcriptomes in different organisms. ncRNAs have different lengths (22 nt to >1, 000 nt) and mechanisms of action that essentially comprise a sophisticated gene expression regulation network. Recent publication of schistosome genomes and transcriptomes has increased...
Outlining fuzzy decision making in maintenance planning
Carvalho, Mariana Teixeira Baptista de; Nunes, Eusébio P.; Telhada, JoséIn any management process, decision making assumes a very important dimension. Complex systems are commonly fed with large amounts of data that are quickly made available to experts and industrial engineers who, in most cases, are not provided with adequate decision support tools. Therefore, the quality of their decisions heavily relies on the quality and experience of them. Indeed, in general, such great avail...
Descoberta de padrões num sistema de certificação de empresas
Carvalho, Mariana Reimão Queiroga Valério deDissertação de mestrado em Engenharia de Informática ; A mineração de dados tem como principal objetivo descobrir padrões escondidos num conjunto de dados, isto é, informação útil que ajude a tomar decisões sobre um determinado tema. Nesta dissertação usa-se a mineração numa base de dados que descreve os certificados adquiridos pelas empresas portuguesas no período 2008-2010. A certificação é um processo volun...
