Growth curves of Leishmania braziliensis braziliensis Promastigotes and surface antigen expression before and after adaptation to Schneider's drosophila medium as assessed by anti-Leishmania human sera

Leishmania braziliensis braziliensis(MHOM/BR/75/M2903) was grown in Schneider's Drosophila medium. In one set of experiments promastigotes were already adapted to the medium by means of serial passages whereas in the second cells were grown in a biphasic medium and transfered to the liquid. Growth was more abundant for culture medium adapted cells; degenerate cells in small numbers as well as dead ones were present from day 5 for promastigotes adapted to liquid medium and from day 3 for newly adapted cells. Synthesis of surface antigens differed according to length of cell culture as assessed by the titer of five mucocutaneous leishmaniasis sera on subsequent days. Five days of culture for cells already adapted to the culture medium and 3 days for newly adapted ones were judged to be the best for the preparation of immunofluorescence antigens.

Growth of the [110] oriented TiO2 nanorods on ITO substrates by sputtering technique for dye-sensitized solar cells

TiO2 films have been deposited on ITO substrates by dc reactive magnetron sputtering technique. It has been found that the sputtering pressure is a very important parameter for the structure of the deposited TiO2 films. When the pressure is lower than 1 Pa, the deposited has a dense structure and shows a preferred orientation along the [101] direction. However, the nanorod structure has been obtained as the sputtering pressure is higher than 1 Pa. These nanorods structure TiO2 film shows a preferred orientation along the [110] direction. The x-ray diffraction and the Raman scattering measurements show both the dense and the nanostructure TiO2 films have only an anatase phase, no other phase has been obtained. The results of the SEM show that these TiO2 nanorods are perpendicular to the ITO substrate. The TEM measurement shows that the nanorods have a very rough surface. The dye-sensitized solar cells (DSSCs) have been assembled using these TiO2 nanorod films prepared at different sputtering pressures as photoelectrode. And the effect of the sputtering pressure on the properties of the photoelectric conversion of the DSSCs has been studied.

O impacto da variação do preço na procura de cuidados de saúde

RESUMO - Assiste-se a um crescimento exponencial das despesas em saúde, quer na Europa como nos Estados Unidos. Em Portugal, os gastos totais com a saúde ascenderam a 10,2% do PIB, em 2006, contra os 8,8% registados no início da década anterior. É importante perceber o que motiva este crescimento quer em termos globais, quer no que diz respeito ao consumo de recursos, bem como até em termos da despesa pública. Este projecto tem dois objectivos fundamentais: em primeiro lugar, contribuir para o estudo dos factores determinantes da procura de cuidados de saúde em Portugal e, consequentemente, determinar as elasticidades procura – preço para diferentes tipos de cuidados de saúde. Metodologia: Estudo observacional baseado na análise empírica de dados administrativos (claims) respeitantes à utilização dos cuidados de saúde por parte de 12.230 indivíduos detentores de um plano de seguro de saúde individual, numa seguradora privada em Portugal. As elasticidades procura – preço para os diferentes tipos de cuidados de saúde obtiveram-se utilizando as variações percentuais das quantidades dos diferentes cuidados de saúde, antes e depois da variação do preço pago pelo indivíduo, para cada tipo de cuidado de saúde. Resultados: De acordo com a teoria económica tradicional o aumento do preço a pagar reduz o consumo de cuidados de saúde, e a procura é elástica, ou seja, os valores da elasticidade procura – preço obtidos são superiores a 1, em valor absoluto, logo o aumento do preço levou a uma redução mais do que proporcional das quantidades procuradas. A procura de cuidados de saúde em ambulatório é mais sensível à variação do preço do que a procura de cuidados de internamento. ------- ABSTRACT - We are witnessing an exponential growth of health care expenditures around the world. In Portugal, the total expenditure on health amounted to 10.2% of GDP in 2006, against 8.8% at the beginning of previous decade. It is important to understand what motivates this growth both in overall terms, with respect to resource consumption, and even in terms of public spending. This study was designed two achieve two objectives: first, to contribute to the study of demand for health care and, more specifically, to analyze the effect of price changes on the utilization of health care services; and secondly, to estimate the demand elasticity for different types of heath care. Methodology: Observational study based on empirical analysis of administrative data (claims) from a private health insurance Company in Portugal. The sample used had information regarding 12.230 individuals. Demand elasticity for the different types of health care services was obtained by the quotient between the percentage changes in the quantity of health care services, before and after the change in the price paid by the corresponding percentage change in the price. Results: This study showed that, for all medical services, price increases were associated with reductions in the quantity of care consumed as predicted by neoclassical demand theory, and we are in the presence of an elastic demand. This means that price elasticity is greater than 1 in absolute value so the increase in the price led to a more than proportional reduction in the quantity demanded. Demand elasticity was more responsive to changes in the price of specialist and emergency care than to changes in the price of inpatient care.

Siderophore Production by Bacillus megaterium: Effect of Growth Phase and Cultural Conditions

Siderophore production by Bacillus megaterium was detected, in an iron-deficient culture medium, during the exponential growth phase, prior to the sporulation, in the presence of glucose; these results suggested that the onset of siderophore production did not require glucose depletion and was not related with the sporulation. The siderophore production by B. megaterium was affected by the carbon source used. The growth on glycerol promoted the very high siderophore production (1,182 μmol g−1 dry weight biomass); the opposite effect was observed in the presence of mannose (251 μmol g−1 dry weight biomass). The growth in the presence of fructose, galactose, glucose, lactose, maltose or sucrose, originated similar concentrations of siderophore (546–842 μmol g−1 dry weight biomass). Aeration had a positive effect on the production of siderophore. Incubation of B. megaterium under static conditions delayed and reduced the growth and the production of siderophore, compared with the incubation in stirred conditions.

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.

Lean and quality management integration: improvement program implementation in a service company

Lean Thinking is an important pillar in the success of any program of continuous improvement process. Its tools are useful means in the analysis, control and organization of important data for correct decision making in organizations. This project had as main objective the design of a program of quality improvement in Eurico Ferreira, S.A., based on the evaluation of customer satisfaction and the implementation of 5S. Subsequently, we have selected which business area of the company to address. After the selection, there was an initial diagnostic procedure, identifying the various points of improvement to which some tools of Lean Thinking have been applied, in particular Value Stream Mapping and 5S methodology. With the first, we were able to map the current state of the process in which all stakeholders were represented as well as the flow of materials and information throughout the process. The 5S methodology allowed to act on the wastage, identifying and implementing various process improvements.
