The effect of olive fruit stoning on virgin olive oil aroma

Olive fruit stoning gives rise to an important modification in olive oil aroma. The level of this modification is a function of the cultivar. An increment in the content of six-carbon compounds (C6) was observed in olive oils obtained from the cultivars Verdial and Manzanilla, but not in the cultivar Picual. In the three cultivars under study, contents of five-carbon compounds (C5) and esters decreased as a consequence of fruit stoning. The modification of olive oil aroma composition in the cultivar Verdial caused by olive fruit stoning was observed to be due both to tissue wounding and to the absence of the olive seed during the crushing-malaxation process to obtain olive oil aroma. Both factors contribute independently to the content modification of C6, C5 compounds and esters in the olive oil aroma from stoned fruits.El deshuesado de la aceituna da lugar a una importante modificación del aroma del aceite de oliva virgen. La intensidad de esta modificación es característica de cada variedad. En los aceites obtenidos de aceitunas Verdial y Manzanilla se produce un incremento en el contenido de los compuestos de seis átomos de carbono (C6) que no se detecta en la variedad Picual. En las tres variedades estudiadas se observa un descenso del contenido de compuestos de cinco átomos de carbono (C5) así como del contenido en ésteres. En la variedad Verdial se ha comprobado que la modificación del aroma como consecuencia del deshuesado del fruto se debe tanto al daño tisular generado durante este proceso como a la ausencia de la semilla durante la molturación de la aceituna. Ambos factores contribuyen de forma independiente a la modificación del contenido de compuestos C6, C5 y ésteres en el aroma del aceite de oliva virgen procedente de aceituna deshuesada.El trabajo se ha realizado en el marco del Proyecto de Investigación AGL2002-02307 del Programa Nacional de Recursos y Tecnologías Agroalimentarias.Peer reviewe

Механизм самовозгорания угля

В работе проведено моделирование процесса зарождения очага эндогенного пожара и намечены пути мобильного определение вероятности его возникновения или наличия. Механизм самовозгорания учитывает процессы тепловыделения при нагревании угля, выделения летучих продуктов, трещинообразование и изменение режима доступа кислорода в очаг реакции в ходе его эволюции. Проведено математическое моделирование процесса самовозгорания угля трех марок угля - антрацит, коксующийся, жирный, проведен расчет динамики температурных полей на поверхности очага самовозгорания, определены критические условия. Для мобильного определения вероятности возникновения или наличия эндогенного пожара предложено использовать беспилотные летательные аппараты.In this work simulation of spontaneous combustion of coal of three grades - anthracite, coking coal, fat in case of lack of oxygen supply and calculation of dynamics of the temperature fields on the surface was made, critical conditions of the hearth of spontaneous combustion were estimated. The mechanism takes into account the processes of heat release, the release of volatile products, cracking and changes in the mode of access of oxygen to the reaction center during its evolution

Prospects of increase of efficiency of functioning of insurance companies through the development of information systems

Russian companies have already been solved (or solved) issues automated support of business processes of insurance. Another aspect of it application in the insurance, which to date remains one of the most important is to support decision-making in the claim process, as it depends largely on the economic condition of the insurance company. To resolve this problem, the development of information systems, the inclusion in their structure of intellectual component, reducing the probability of errors when making decisions. The work of this component is based on the principles of the decision theory and artificial intelligence, uses the mathematical apparatus of decision-making in conditions of uncertainty and risk and is a tool that interacts with the information system of the company
