Malaria serology: performance of six Plasmodium falciparum antigen extracts and of three ways of determining serum titers in IgG and IgM-ELISA

The study evaluated six Plasmodium falciparum antigen extracts to be used in the IgG and IgM enzyme-linked immunosorbent assays (ELISA), for malaria diagnosis and epidemiological studies. Results obtained with eighteen positive and nine negative control sera indicated that there were statistically significant differences among these antigen extracts (Multifactor ANOVA, p< 0.0001). Urea, sodium deoxycholate and Zwittergent antigen extracts performed better than did the three others, their features being very similar for the detection of IgG antibodies. Urea, alkaline and sodium deoxycholate antigen extracts proved to be better than the others for the detection of IgM antibodies. A straight line relationship was found between the optical densities (or their respective log 10) and the log 10 of antibody dilutions, with a very constant slope. Thus serum titers could be determined by direct titration and by two different equations, needing only one serum dilution. For IgM antibody detections, log 10 expression gave results that better correlated with direct titration (95% Bonferroni). For IgG antibody detections, the titer differences were not significant. The reproducibility of antibody titers and antigen batches was also evaluated, giving satisfactory results.

Road drivers performance appraisal using a MCDA method: a case study in the road transport company

Performance evaluation increasingly assumes a more important role in any organizational environment. In the transport area, the drivers are the company’s image and for this reason it is important to develop and increase their performance and commitment to the company goals. This evaluation can be used to motivate driver to improve their performance and to discover training needs. This work aims to create a performance appraisal evaluation model of the drivers based on the multi-criteria decision aid methodology. The MMASSI (Multicriteria Methodology to Support Selection of Information Systems) methodology was adapted by using a template supporting the evaluation according to the freight transportation company in study. The evaluation process involved all drivers (collaborators being evaluated), their supervisors and the company management. The final output is a ranking of the drivers, based on their performance, for each one of the scenarios used.

The need of performance indicators for collaborative business ecosystems

During last decades there has been a trend to build collaboration platforms as enablers for groups of enterprises to jointly provide integrated services and products. As a result, the notion of business ecosystem is getting wider acceptance. However, a critical issue that is still open, despite some efforts in this area, is the identification of adequate performance indicators to measure and motivate sustainable collaboration. This work-in-progress addresses this concern, briefly presenting the state of the art of relevant contributing areas such as, collaborative networks, business ecosystems, enterprise performance indicators, social networks analysis, and supply chains. Complementarily, through an assessment of current gaps, the research challenges are identified and an approach for further development is proposed.

Off-the-person electrocardiography: performance assessment and clinical correlation

Previous work by our group introduced a novel concept and sensor design for “off-the-person” ECG, for which evidence on how it compares against standard clinical-grade equipment has been largely missing. Our objectives with this work are to characterise the off-the-person approach in light of the current ECG systems landscape, and assess how the signals acquired using this simplified setup compare with clinical-grade recordings. Empirical tests have been performed with real-world data collected from a population of 38 control subjects, to analyze the correlation between both approaches. Results show off-the-person data to be correlated with clinical-grade data, demonstrating the viability of this approach to potentially extend preventive medicine practices by enabling the integration of ECG monitoring into multiple dimensions of people’s everyday lives. © 2015, IUPESM and Springer-Verlag Berlin Heidelberg.

Performance of concrete made with recycled aggregates from Portuguese CDW recycling plants

The objective of this research is the production of concrete with recycled aggregates (RA) from various CDW plants around Portugal. The influence of the RA collection location and consequently of their composition on the characteristics of the concrete produced was analysed. In the mixes produced in this research RA from five plants (Valnor, Vimajas, Ambilei, Europontal and Retria) were used: in three of them coarse and fine RA were analysed and in the remaining ones only coarse RA were used. The experimental campaign comprised two tests in fresh concrete (cone of Abrams slump and density) and eight in hardened concrete (compressive strength in cubes and cylinders, splitting tensile strength, modulus of elasticity, water absorption by immersion and capillarity, carbonation and chloride penetration resistance). It was found that the use of RA causes a quality decrease in concrete. However, there was a wide results scatter according to the plant where the RAs were collected, because of the variation in composition of the RA. It was also found that the use of fine RA causes a more significant performance loss of the concrete properties analysed than the use of coarse RA. © (2015) Trans Tech Publications, Switzerland.

Força Muscular Isocinética após Reconstrução do Ligamento Cruzado Anterior – Influência do Tipo de Enxerto (Osso-Tendão-Osso/Isquio-Tibiais)

Introdução: É reconhecida a importância do ligamento cruzado anterior (LCA) no funcionamento normal do joelho. Em caso de rotura ligamentar, nomeadamente em desportos com marcada solicitação dos movimentos de rotação do joelho, é justificada a necessidade de reconstrução do LCA na maioria dos casos. Objetivo (s): Avaliar a influência do tipo de enxerto na reconstrução do ligamento cruzado anterior na força muscular isocinética, assim como na funcionalidade e sintomas após 6 meses. Métodos: Estudo transversal analítico, constituído por 20 indivíduos voluntários do sexo masculino, que haviam sido submetidos a uma ligamentoplastia do cruzado anterior, pelo mesmo cirurgião, seguido de uma intervenção individualizada por um fisioterapeuta. Em 10 indivíduos, o procedimento cirúrgico foi realizado com enxerto do tendão rotuliano (grupo OTO), e nos restantes 10 com enxerto do semitendinoso e gracilis (grupo STG). Como forma de avaliar a Força Muscular Isocinética (Peak Torque, Trabalho Total Muscular, ratio Isquiotibiais/Quadricipite), foi utilizado o Dinamómetro Isocinético Biodex. A avaliação foi efectuada apenas aos 6 meses após o procedimento cirúrgico. Para observação da funcionalidade, amplitude de movimento e sintomas, utilizou-se o questionário International Knee Documentation Committee (IKDC). Resultados: Foi possível observar que entre os grupos apenas se observaram diferenças significativas no peak torque de extensão a 180º no membro não lesado (p=0,019). Contudo, foi observada uma tendência para o grupo OTO apresentar um maior défice no peak torque e trabalho total muscular em extensão. Comparativamente ao membro contra-lateral, o membro lesado apresentou valores significativamente inferiores na maioria das variáveis ( p < 0,05). Conclusão: Após 6 meses de pós-cirúrgico com reabilitação de fisioterapia, não foi possível apontar qual o enxerto que garante uma melhor recuperação da força muscular. Aos 6 meses, ambos os grupos ainda apresentaram limitações musculares, quando comparados com o lado contra-lateral. Relativamente ao rácio isquiotibiais/quadricípite, assim como no IKDC, não se observaram diferenças entre os dois tipos de enxertos.

MCDA applied to performance appraisal of short-haul truck drivers: a case study in a portuguese trucking company

Performance appraisal increasingly assumes a more important role in any organizational environment. In the trucking industry, drivers are the company's image and for this reason it is important to develop and increase their performance and commitment to the company's goals. This paper aims to create a performance appraisal model for trucking drivers, based on a multi-criteria decision aid methodology. The PROMETHEE and MMASSI methodologies were adapted using the criteria used for performance appraisal by the trucking company studied. The appraisal involved all the truck drivers, their supervisors and the company's Managing Director. The final output is a ranking of the drivers, based on their performance, for each one of the scenarios used. The results are to be used as a decision-making tool to allocate drivers to the domestic haul service.
