Effect of Enzyme Addition in the Making of Pedro Ximenez Sweet Wines Using Dynamic Pre-fermentative Maceration

This work evaluated the effect of two commercial pectolytic enzymes on some oenological parameters before andafter enzymatic treatments with pre-fermentative dynamic maceration at room temperature for three hours. Thestudy was conducted on an industrial scale using musts from sun-dried grapes of the Pedro Ximenez variety.Statistical analysis and sensory rating showed that the resulting wines varied significantly in total soluble solids(ºBrix) and in the final sensorial controls. On the other hand, the enzyme treatment had no effect on the contentof total polyphenols (TPI) and other chemical characteristics of the obtained musts. A higher qualitative level wasobserved with regard to aroma and gustative quality compared to the control. The results also demonstrate thattotal juice yield improved after enzyme addition together with dynamic maceration

Factores de riesgo y consecuencias de las caídas en los residentes de un Centro Geriátrico Asistido.

Estudio Realizado sobre el fenómeno de las caídas con una muestro de 79 ancianos de un Centro Geriátrico Asistido para valorar la incidencia de determinados factores de riesgo intrínsecos y extrínsecos, así como sus consecuencias físicas y psíquicas (síndrome post-caída), evolución y tratamiento. El 80% de los ancianos sufrieron alguna caída. Las pruebas estadísticas realizadas mostraron que los ancianos que consumen benzodiacepinas e hipnóticos presentan mayor número de caídas que los que no consumen dichos fármacos, y lo mismo ocurre con el hecho de padecer demencia. La ocurrencia de las caídas también se estudió, mostrando los resultados una incidencia significativa del consumo de benzodiacepinas e hipnóticos (U=1119, p<0.001) y de neurolépticos (U=870, p<0.001). También inciden la demencia (U=937, p<0.0031 y Ios accidentes cerebro vasculares (U=347, p<0.007). El 15% de las caídas se debieron a enfermedades interrecurrentes o agudas, y un 5.1% terminaron en fractura. El 18.99% de los ancianos que sufrieron caídas mostraron el síndrome post-caída de modo objetivable

Representative elementary area for multifractal analysis of soil porosity using entropy dimension

International audienceThe notion of representative elementary area (REA) developed to address heterogeneity and scale problems in quantitative soil pedology comes from the notion of representative elementary volume of fluid dynamics in porous media. The REA allows the identification of the minimum area of a soil block section that is required to represent the pedofeature of interest based on its distribution in soil space. In this paper eight samples were imaged with two different techniques: the confocal microscope and the conventional film camera. These techniques provided information about pore sizes between 3.62 ?m and 161.98 ?m, and between 39.72 ?m and 1776.34 ?m, respectively. Sixteen of the resulting digital images were then analyzed to investigate the representative elementary area of the multifractal patterns of the spatial distribution of voids related to the micro and macroporosity by means of the entropy dimension. Our results permit the location of the REA region over the domain of the microstructures rendered by the analysis of the microscope images. They also suggest that this region seemingly spans scales of the macrostructures as revealed by the analysis of the camera pictures

3D MODELLING OF THE NEGRO TOWER FOR ITS COMPREHENSIVE ANALYSIS AND A CONSERVATION PROPOSAL

Abstract. The Negro Tower, in El Algar, Cartagena (Region of Murcia, Spain), is a building which dates to 1585. It is a tower built in a rural environment, inland from the coast, to alert and protect the population from pirate attacks. It was part of the network of watchtowers and defense posts along the coast of Murcia built between the sixteenth and seventeenth centuries. The tower is protected as a historical monument, but its state of conservation is very poor. For this reason, a comprehensive study has been carried out to ensure its correct restoration and future conservation. Historical and constructive analysis has allowed us to discover the social, cultural and architectural characteristics of the tower. Digital photogrammetry and 3D laser scanning compatible with classic topography have been used for the graphic survey of the tower. All this information has permitted the elaboration of thorough three-dimensional modelling and the proposal of a volumetric recomposition of the tower. The presentation will set out the working methodology followed as well as the important results achieved. This research work aims to contribute to the recognition and correct conservation of the Tower. The graphic survey and the three-dimensional model obtained will allow the recovery of the tower and its integration into the natural environment

Long-Term Stability of TiS2–Alkylamine Hybrid Materials

Layered TiS2 intercalated with linear alkylamines has recently attracted significant interest as a model compound for flexible n-type thermoelectric applications, showing remarkably high power factors at room temperature. The thermal and, particularly, environmental stability of such materials is, however, a still an open challenge. In this paper, we show that amine-intercalated TiS2 prepared by a simple mechanochemical process is prone to chemical decomposition through sulfur exsolution, and that the presence of molecular oxygen is likely to mediate the decomposition reaction. Through computational analysis of the possible reaction pathways, we propose that Ti-N adducts are formed as a consequence of amine groups substituting for S vacancies on the internal surfaces of the S-Ti-S layers. These findings provide insights for possible future applications of similar hybrid compounds as devices operating in ambient conditions, and suggest isolating them from atmospheric oxygen

A dynamic explanation for the origin of the western Mediterranean organic-rich layers

The eastern Mediterranean sapropels are among the most intensively investigated phenomena in the paleoceanographic record, but relatively little has been written regarding the origin of the equivalent of the sapropels in the western Mediterranean, the organic-rich layers (ORLs). ORLs are recognized as sediment layers containing enhanced total organic carbon that extend throughout the deep basins of the western Mediterranean and are associated with enhanced total barium concentration and a reduced diversity (dysoxic but not anoxic) benthic foraminiferal assemblage. Consequently, it has been suggested that ORLs represent periods of enhanced productivity coupled with reduced deep ventilation, presumably related to increased continental runoff, in close analogy to the sapropels. We demonstrate that despite their superficial similarity, the timing of the deposition of the most recent ORL in the Alboran Sea is different than that of the approximately coincident sapropel, indicating that there are important differences between their modes of formation. We go on to demonstrate, through physical arguments, that a likely explanation for the origin of the Alboran ORLs lies in the response of the western Mediterranean basin to a strong reduction in surface water density and a shoaling of the interface between intermediate and deep water during the deglacial period. Furthermore, we provide evidence that deep convection had already slowed by the time of Heinrich Event 1 and explore this event as a potential agent for preconditioning deep convection collapse. Important differences between Heinrich-like and deglacial-like influences are highlighted, giving new insights into the response of the western Mediterranean system to external forcing

Aggregation-based information retrieval system for geospatial data catalogs

Geospatial data catalogs enable users to discover and access geographical information. Prevailing solutions are document oriented and fragment the spatial continuum of the geospatial data into independent and disconnected resources described through metadata. Due to this, the complete answer for a query may be scattered across multiple resources, making its discovery and access more difficult. This paper proposes an improved information retrieval process for geospatial data catalogs that aggregates the search results by identifying the implicit spatial/thematic relations between the metadata records of the resources. These aggregations are constructed in such a way that they match better the user query than each resource individually

Papel da análise discriminante no aprimoramento da avaliação da satisfação dos usuários

OBJECTIVE: To test discriminant analysis as a method of turning the information of a routine customer satisfaction survey (CSS) into a more accurate decision-making tool. METHODS: A 7-question, 10-multiple choice, self-applied questionnaire was used to study a sample of patients seen in two outpatient care units in Valparaíso, Chile, one of primary care (n=100) and the other of secondary care (n=249). Two cutting points were considered in the dependent variable (final satisfaction score): satisfied versus unsatisfied, and very satisfied versus all others. Results were compared with empirical measures (proportion of satisfied individuals, proportion of unsatisfied individuals and size of the median). RESULTS: The response rate was very high, over 97.0% in both units. A new variable, medical attention, was revealed, as explaining satisfaction at the primary care unit. The proportion of the total variability explained by the model was very high (over 99.4%) in both units, when comparing satisfied with unsatisfied customers. In the analysis of very satisfied versus all other customers, significant relationship was identified only in the case of the primary care unit, which explained a small proportion of the variability (41.9%). CONCLUSIONS: Discriminant analysis identified relationships not revealed by the previous analysis. It provided information about the proportion of the variability explained by the model. It identified non-significant relationships suggested by empirical analysis (e.g. the case of the relation very satisfied versus others in the secondary care unit). It measured the contribution of each independent variable to the explanation of the variation of the dependent one.OBJETIVO: Testar a análise discriminante como um método de transformar a informação obtida num inquérito de satisfação dos usuários de rotina numa acurada ferramenta de tomada de decisão. MÉTODOS: Utilizou-se questionário auto-aplicável com sete questões de dez opções numa amostra dos pacientes atendidos em duas unidades ambulatórias públicas, em Valparaíso, Chile, sendo uma de cuidados primários (n=100) e a outra de atenção secundária (n=249). Utilizaram-se dois pontos de corte na variável dependente (índice final de satisfação): satisfeitos vs insatisfeitos e muito satisfeitos vs os demais. Os resultados foram comparados com medidas empíricas habitualmente utilizadas (proporção de satisfeitos, proporção de insatisfeitos e dimensão da mediana). RESULTADOS: O nível de resposta foi muito elevado (sempre acima de 97,0%). Uma variável adicional revelou-se (atendimento médico), explicando a satisfação com o atendimento na unidade primária. Ao comparar satisfeitos com insatisfeitos, a proporção total da variabilidade explicada pelo modelo foi muito elevada (acima de 99,4%) em ambas unidades. Ao comparar muito satisfeitos com os demais, observou-se relação significativa apenas no caso da unidade primária. Explicou-se uma baixa proporção da variabilidade (41,9%). CONCLUSÕES: A análise discriminante revelou relações não percebidas pela análise empírica e indicou a proporção exata da variabilidade explicada pelo modelo utilizado. A técnica afastou como não significativas relações sugeridas pela análise empírica (por exemplo, muito satisfeitos versus os demais no caso da unidade secundária). A técnica permitiu medir a intensidade da contribuição de cada variável na explicação da variação da satisfação
