- Aplicações desenvolvidas no ambito da metrologia eléctrica e de vibração no INETIPublication . Ribeiro, Luís; Godinho, Maria Isabel; Cabral, Alexandre Pereira; Oliveira, Vitor; Nunes, Mário Constanzo; Rebordão, José ManuelSão apresentados diversos módulos desenvolvidos em ambiente LabView, para controlo de instrumentação, processamento e tratamento estatístico de dados e determinação de incertezas, aplicados aos domínios da Metrologia Eléctrica e de Vibração no INETI. É efectuada uma breve síntese do contexto técnico em que cada uma das aplicações se insere assim como uma descrição dos principais aspectos associados a cada módulo.
- Blog SWOT organizacionalPublication . Pinheiro, Mónica; Cardoso, MargaridaProcura-se analisar o impacto potencial dos weblogs nas organizações, salientando a relevância de determinadas características desta ferramenta de comunicação mediada por computador, centrada no utilizador, perante algumas das características das organizações. Mais exactamente, como é que o blog, sendo simples de utilizar, tecnicamente acessível e de custo praticamente nulo (para além da infraestrutura de suporte), se converte num meio acessível desde grandes a micro-empresas onde, nestas últimas, já se verificam múltiplos exemplos de utilização, sendo meio e condicionante na multiplicação de valor. A utilização dos critérios de análise SWOT constitui-se como estrutura de base desta comunicação, com vista a alargar o leque de situações e contextos de utilização.
- Building a collaboratory in an engineering R&D organizationPublication . Correia, Zita; Egreja, Catarina; Barrulas, Maria Joaquina; Gil, Rui; Ferreira, Diogo R.This paper presents the results achieved throughout the process of preparing the ground to develop a collaboratory in an Engineering R&D organization. This case study is part of a broader research project engaged in building a collaboratory in order to share knowledge and resources among the Portuguese State laboratories. In the process of preparing the ground to develop the collaboratory in the first of the laboratories studied, an information audit was conducted and an online survey was launched. The survey targeted 241 people, including mainly professional researchers, but also research trainees and some technical staff integrating the research teams. The questionnaire was designed so as to collect data on the organization’s information management and information culture, and on the information flows taking place, and their relationship with the objectives of the organization. The questionnaire comprised two distinct and independent parts. The first (on the organization’s information culture and information management) obtained seventy nine responses, while the second (information flows) achieved ninety two, corresponding to 32,8% and 38,2% of the total population, respectively. The work carried out provided the basic requirements for the task of developing a software infrastructure to support the collaboratory, addressing the various aspects of collaborative tools, information archiving, hierarchical tag classification, search, transparent integration of the user local environment with the platform and remote control of scientific instruments.
- Building a collaboratory in an engineering R&D organizationPublication . Correia, Zita; Egreja, Catarina; Barrulas, Maria Joaquina; Gil, Rui; Ferreira, Diogo R.; Cunha, Luís Arriaga daThis paper presents the results achieved so far in the process of preparing the ground to develop a collaboratory in an Engineering R&D organization. This case study is part of a broader research project engaged in building a collaboratory in order to share knowledge and resources among the Portuguese State Laboratories. In the process of preparing the ground to develop the collaboratory in the first of the State Laboratories studied, an information audit was conducted and an online survey was launched. The survey targeted 240 people, including mainly professional researchers (c. 160), but also research trainees and some technical staff integrating the research teams. The questionnaire was designed so as to collect data on the information management and information culture of the organization, on the researchers’ information needs and information seeking, and on the information flows taking place, and was composed of two distinct and independent parts. The first obtained seventy nine responses, while the second achieved ninety two, corresponding to 33% and 38% of the total sample, respectively. The work carried out will provide the basic requirements for the task of developing an infrastructure and tools for the collaboratory, addressing the various aspects of collaborative software tools, information archiving and intelligent search, remote control of scientific instruments and multi-channel access to the services.

- Cork agglomerates as an ideal core material in lightweight structuresPublication . Castro, Osvaldo; Silva, José M.; Devezas, Tessaleno; Silva, Arlindo; Gil, LuísThe experiments carried out in this investigation were oriented in order to optimize the properties of cork-based agglomerates as an ideal core material for sandwich components of lightweight structures, such as those used in aerospace applications. Static bending tests were performed in order to characterize the mechanical strength of different types of cork agglomerates which were obtained considering distinct production variables. The ability to withstand dynamic loads was also evaluated from a set of impact tests using carbon-cork sandwich specimens. The results got from experimental tests revealed that cork agglomerates performance essentially depends on the cork granule size, its density and the bonding procedure used for the cohesion of granulates, and these parameters can be adjusted in function of the final application intended for the sandwich component. These results also allow inferring that optimized cork agglomerates have some specific properties that confirm their superior ability as a core material of sandwich components when compared with other conventional materials.
- Detection of bovine Babesiosis in Mozambique by a novel seminested hot-start PCR method.Publication . Martins, Tiago M.; Pedro, Olívia C.; Rubina, Caldeira; Rosário, Virgílio do; Neves, L.; Domingos, AnaBabesiosis is a tick borne disease (TBD) caused by parasites of the genus Babesia, with considerable worldwide economic, medical, and veterinary impact. Bovine babesiosis and other TBDs were considered responsible for 50% of the deaths of cattle that occurred in Mozambique in the first year after importation from neighbouring countries. Here, we present the detection of Babesia bigemina and Babesia bovis in cattle from Mozambique using two distinct PCR methods. For this study, blood samples were collected in one farm located near Maputo city. The DNA samples were analyzed using a previously described nested PCR and a novel hot-start PCR method. Primers were selected for the hot-start PCR based on the putative gene of an undescribed aspartic protease named babesipsin, present in both B. bovis and B. bigemina. The combination of hot-start polymerase and long primers (29–31 bp) were in this study determinant for the successful amplification and detection in only one PCR. With a seminested approach the sensitivity was further increased. The babesipsin seminested hot-start PCR was in this study more sensitive than the nested PCR. A total of 117 field samples were tested by seminested hot-start PCR, and 104 were positive for B. bigemina (90%), 97 were positive for B. bovis (82%), 86 were mixed infections (52%) and only 2 were negative for both Babesia species (1.7%). The results confirm that this area of Mozambique is endemic for babesiosis, and that this TBD should be regarded as a threat for imported cattle.
