A dimensão económica, financeira, social, cultural e desportiva que o futebol de alto rendimento alcançou parece exigir da parte dos clubes/SAD`s e de todos os intervenientes no processo uma responsabilização elevada face aos capitais envolvidos e à permanente necessidade de os rentabilizar. A relação entre clube/SAD e treinador parece ser causadora de constrangimentos, que conduzem a ruturas que em muitas das situações acarretam custos elevados para ambas as partes. Estudar a articulação entre o que o clube/SAD se propõe produzir e o papel do treinador de alto rendimento na modalidade de futebol, perceber quais as dinâmicas e sinergias passíveis de serem criadas, identificando um conjunto de variáveis e respetivos indicadores que permitam uma gestão mais eficiente, parece-nos ser de extrema importância para que se consiga rentabilizar todo o processo. Desta forma apresentamos uma proposta de grelha de leitura de clube/SAD que nos parece possibilitar uma articulação mais eficiente, e uma otimização da relação existente ente a micro e a macro gestão.

The consumer interest in healthy foods with high amounts of antioxidants is one of the important factors for reducing the risk of disease and it has encouraged researchers and industry to develop innovative and functional products and ingredients. To that end, the objective of this research was to study the bioactive compounds present in the acai pulp, blueberry and goji berry samples, as well as the phenolic compounds form of extraction using the response surface methodology (RSM), antioxidant and antimicrobial activity of it, identification and quantification of compounds by high-performance liquid chromatography (HPLC) and, at the end, the development of petit suisse cheeses added with freeze-dried extracts of the samples. A 2³ factorial design was used to analyze the solvent effect (ethanol and water), time (30 and 60 min) and temperature (30 °C and 60 °C) on the extraction and determination of total phenolic compounds (TPC) and antioxidant activity (AA). The variables time and temperature had a positive effect on the antioxidant activity (AA) in their highest levels with 60 min and 60 °C respectively. The ethanol solvent 80 % is more efficient in TPC extraction with AA in all arrays. The identification of phenolic compounds performed by HPLC revealed the presence of catechin, epicatechin, rutin, myricetin, chlorogenic acid, coumaric acid and ferulic acid. Regarding the AA the acai pulp showed higher activity in vitro when extracted by 60 °C for 60 min, but none of the three extracts analyzed under these conditions showed antibacterial activity against Staphylococcus aureus and Salmonella bongori in the concentrations tested (95.00 to 2.34 mg/mL. For petit suisse cheeses added with phenolic extract of the samples, the sample containing goji berry achieved greater sensory acceptance among judges (75.67%), second only to the commercial sample used for comparison with 91.56 % of acceptance. In relation to the storage time, the oxidation was evaluated by the level of thiobarbituric acid reactive substances and color analysis. Both analysis were satisfactory, making the extracts addition an alternative to preserve the product properties and give it a high content of bioactive and nutritive compounds.

A frequently encountered difficulty in oral prosthetics is associated with the loss of metallic alloys during the melting stage of the production of metal-ceramic replacement systems. Remelting such materials could impar their use in oral rehabilitation due to loss in esthetics, as well as in the chemical, physical, electrochemical and mechanical properties. Nowadays, the Ni-Cr-Mo-Ti alloy is widely used in metal-ceramic systems. Manufacturers state that this material can be remelted without significant alterations in its behavior, however little has been established as to the changes in the performance of this alloy after successive remelting, which is common practice in oral prosthetics. Therefore, the objective of this study was to evaluate possible changes in the esthetics and associated properties of metalceramic samples consisting of Ni-Cr-Mo-Ti and dental porcelain. Three to five remelting steps were carried out. The results revealed that Ni-Cr-Mo-Ti can be safely used even after three remelting steps. Further remelting significantly affect the characteristics of the alloys and should not be recommended for the manufacture of metal-ceramic systems

Nickel alloys are frequently used in applications that require resistance at high temperatures associated with resistance to corrosion. Alloys of Ni-Si-C can be obtained by means of powder metallurgy in which powder mixtures are made of metallic nickel powders with additions of various alloying carriers for such were used in this study SiC, Si3N4 or Si metal with graphite. Carbonyl Ni powder with mean particle size of 11 mM were mixed with 3 wt% of SiC powders with an average particle size of 15, 30 and 50 μm and further samples were obtained containing 4 to 5% by mass of SiC with average particle size of 15 μm. Samples were also obtained by varying the carrier alloy, these being Si3N4 powder with graphite, with average particle size of 1.5 and 5 μm, respectively. As a metallic Si graphite with average particle size of 12.5 and 5 μm, respectively. The reference material used was nickel carbonyl sintered without adding carriers. Microstructural characterization of the alloys was made by optical microscopy and scanning electron microscopy with semi-quantitative chemical analysis. We determined the densities of the samples and measurement of microhardness. We studied the dissociation of carriers alloy after sintering at 1200 ° C for 60 minutes. Was evaluated also in the same sintering conditions, the influence of the variation of average particle size of the SiC carrier to the proportion of 3% by mass. Finally, we studied the influence of variation of the temperatures of sintering at 950, 1080 and 1200 ° C without landing and also with heights of 30, 60, 120 and 240 minutes for sintering where the temperature was 950 °C. Dilatometry curves showed that the SiC sintered Ni favors more effectively than other carriers alloy analyzed. SiC with average particle size of 15 μm active sintering the alloy more effectively than other SiC used. However, with the chemical and morphological analyzes for all leagues, it was observed that there was dissociation of SiC and Si3N4, as well as diffusion of Si in Ni matrix and carbon cluster and dispersed in the matrix, which also occurred for the alloys with Si carriers and metallic graphite. So the league that was presented better results containing Si Ni with graphite metallic alloy as carriers, since this had dispersed graphite best in the league, reaching the microstructural model proposed, which is necessary for material characteristic of solid lubricant, so how we got the best results when the density and hardness of the alloy

El principal objetivo de este trabajo ha sido determinar el impacto del coste total de las pensiones del País Vasco a pagar hacia el futuro. Para ello hemos recabado información del colectivo de Euskadi, y además de haber analizado su evolución respecto a algunos elementos demográficos, también hemos obtenido la información estadística necesaria para la elaboración del tanto central de mortalidad (para cada año de edad y año de calendario). Con los datos obtenidos se ha procedido a realizar un análisis de sensibilidad comparando los resultados que se obtienen al aplicar la tabla de mortalidad propia, creada a partir del tanto central de mortalidad (mx), con la tabla PASEM-2010 y la PERM/F-2000, de uso frecuente en las transacciones de seguros. En relación a los datos más destacados en este trabajo, se aprecia que hay una gran similitud, entre los resultados obtenidos respecto a los costes de las pensiones de jubilación, aplicando la tabla que se ha elaborado a partir de las estadísticas de defunciones y población especificas del País Vasco, y la PERM/F-2000, 2000. Por otro lado, se observan grandes desviaciones en los costes de las pensiones reduciéndose en el caso de la tabla PASEM-2010 o aumentando en el caso de PERM/F-2000, 2010, respecto al resto tablas utilizadas.
