This work proposes the detection of red peaches in orchard images based on the definition of different linear color models in the RGB vector color space. The classification and segmentation of the pixels of the image is then performed by comparing the color distance from each pixel to the different previously defined linear color models. The methodology proposed has been tested with images obtained in a real orchard under natural light. The peach variety in the orchard was the paraguayo (Prunus persica var. platycarpa) peach with red skin. The segmentation results showed that the area of the red peaches in the images was detected with an average error of 11.6%; 19.7% in the case of bright illumination; 8.2% in the case of low illumination; 8.6% for occlusion up to 33%; 12.2% in the case of occlusion between 34 and 66%; and 23% for occlusion above 66%. Finally, a methodology was proposed to estimate the diameter of the fruits based on an ellipsoidal fitting. A first diameter was obtained by using all the contour pixels and a second diameter was obtained by rejecting some pixels of the contour. This approach enables a rough estimate of the fruit occlusion percentage range by comparing the two diameter estimates.

The appearance of the Banco de Barcelona involved the formation of an investment compact network between its directors. In this work we studied how this investment network grew within a larger one, the one formed by the major investors in Catalonia during the period 1815-1866, as well as the role played by the top executives of the Bank inside it. Our findings indicate that some of the directors of the Bank held a central position in the main Catalan investors" network. This important role guaranteed reliable information on the progress of businesses. This information not only favored the operations of the institution, but also allowed its directors to take investment decisions inside the network. Moreover, the Bank interconnects individuals who were associated with different investors" sectors, which made the institution coalesced around an investing core with different important influences and connections.

Background: Hyperhomocysteinemia and methylenetetrahydrofolate reductase (MTHFR) gene mutation have been postulated as a possible cause of recurrent miscarriage (RM). There is a wide variation in the prevalence of MTHFR polymorphisms and homocysteine (Hcy) plasma levels among populations around the world. The present study was undertaken to investigate the possible association between hyperhomocysteinemia and its causative genetic or acquired factors and RM in Catalonia, a Mediterranean region in Spain. Methods: Sixty consecutive patients with ≥ 3 unexplained RM and 30 healthy control women having at least one child but no previous miscarriage were included. Plasma Hcy levels, MTHFR gene mutation, red blood cell (RBC) folate and vitamin B12 serum levels were measured in all subjects. Results: No significant differences were observed neither in plasma Hcy levels, RBC folate and vitamin B12 serum levels nor in the prevalence of homozygous and heterozygous MTHFR gene mutation between the two groups studied. Conclusions: In the present study RM is not associated with hyperhomocysteinemia, and/or the MTHFR gene mutation.

El artículo se inicia con una reflexión en torno al hecho de que las inter- venciones centradas en las familias de niños con discapacidad intelectual pueden ser consideradas como una contribución a su calidad de vida. A partir de aquí se revisa brevemente el concepto de calidad de vida, su evolución y su aplicación en el ámbito de las familias de personas con dis- capacidad intelectual. Se presenta una revisión de investigaciones en el ámbito de la intervención naturalista en la comunicación y el lenguaje, basadas en teorías funcionales e interactivas del desarrollo, tanto centra- das en el trabajo directo con el niño como centradas en la familia. Se presentan resultados de intervenciones naturalistas llevadas a cabo en nuestro país cen- tradas tanto en niños con discapacidad intelectual como en sus familias. Finalmente, se defiende que para conseguir una mayor calidad de vida de los niños con discapacidad intelectual y sus familias, debemos optar por una nueva metodología que suponga un trabajo coordinado y compartido, desde el inicio, entre todos los profesionales e instituciones implicados en el proceso

Background: Few clinical studies have focused on the alcoholindependent cardiovascular effects of the phenolic compounds of red wine (RW). Objective: We aimed to evaluate the effects of ethanol and phenolic compounds of RW on the expression of inflammatory biomarkers related to atherosclerosis in subjects at high risk of cardiovascular disease. Design: Sixty-seven high-risk, male volunteers were included in a randomized, crossover consumption trial. After a washout period, all subjects received RW (30 g alcohol/d), the equivalent amount of dealcoholized red wine (DRW), or gin (30 g alcohol/d) for 4 wk. Before and after each intervention period, 7 cellular and 18 serum inflammatory biomarkers were evaluated. Results: Alcohol increased IL-10 and decreased macrophage-derived chemokine concentrations, whereas the phenolic compounds of RW decreased serum concentrations of intercellular adhesion molecule- 1, E-selectin, and IL-6 and inhibited the expression of lymphocyte function-associated antigen 1 in T lymphocytes and macrophage-1 receptor, Sialil-Lewis X, and C-C chemokine receptor type 2 expression in monocytes. Both ethanol and phenolic compounds of RW downregulated serum concentrations of CD40 antigen, CD40 ligand, IL-16, monocyte chemotactic protein-1, and vascular cell adhesion molecule-1. Conclusion: The results suggest that the phenolic content of RW may modulate leukocyte adhesion molecules, whereas both ethanol and polyphenols of RW may modulate soluble inflammatory mediators in high-risk patients. The trial was registered in the International Standard Randomized Controlled Trial Number Register at http://www. isrctn.org/ as ISRCTN88720134

La transición a la edad adulta y vida activa es un proceso extremadamente complejo para los jóvenes con discapacidad. Para plantear propuestas de actuación que mejoren sus oportunidades de conseguir objetivos relacionados con la inclusión laboral y social en la vida adulta es imprescindible el diagnóstico en profundidad del contexto en que se construyen y desarrollan los procesos de transición. En este artículo se presenta un estudio en el que se ha aplicado el método Delphi con el propósito de obtener datos sobre la adecuación de los servicios o dispositivos que trabajan con jóvenes con discapacidad a lo largo de su proceso de transición a la edad adulta y vida activa, tanto en el escenario escolar como en el postescolar. Se han constituido dos paneles de expertos, uno con profesionales del ámbito educativo y otro con profesionales que trabajan en servicios postescolares. En ambos casos, los ejes temáticos son: visión del proceso de transición, aspectos curriculares y organizativos de los servicios, existencia de itinerarios de apoyo sistematizados, trabajo colaborativo entre profesionales, acciones de orientación con familias, adecuación de las alternativas postescolares, la formación de los profesionales, y coordinación de servicios. El análisis de los cuestionarios permite constatar las principales dificultades percibidas por los expertos en cada uno de los ámbitos y establece líneas básicas de actuación para mejorar los procesos de tránsito, entre las cuales destaca la necesidad de reforzar el papel de los equipos multiprofesionales en la articulación de redes de trabajo interprofesional

This article is part of a research focusing on the process of transition to adulthood of young people with intellectual disabilities. Specifically, this study analyses transition partnership programs, as the professionals involved in them see them. The information is obtained in two stages: in the first stage 45 interviews to professionals working in this field are conducted. In the second stage we develop a study applying the Delphi method in which two panels of experts, the first one with educational professionals and the second one with professionals working with afters chool services, were asked about several topics. The results show a lack of continuity underlying the actions taken in support of young people with ID during the transition process. Insufficient information and collaboration among services and professionals and a lack of leadership are the main problems perceived by professionals. The study helps to identify problems in the transition partnership programs and establishes actions in order to enhance the transition process
