    Full Text Available Actualmente, los consumidores de fruta son altamente exigentes tanto en la calidad externa como interna de la fruta. En el aspecto externo, exigen ausencia de daños causados por plagas y/o enfermedades con énfasis en aquellas consideradas cuarentenarias como es Mancha Negra (MN causada por el hongo Guignardia citricarpa Kiely. Con respecto a los aspectos internos, se considera que debe tener alta calidad organoléptica y, sobre todo, tener mínimos residuos de plaguicidas. Para contribuir con ambos objetivos, se están realizando desde hace varios años tratamientos para optimizar la dosis de fungicidas y volúmenes aplicados a lotes con frutas con destino de exportación. A tal efecto se han realizado ensayos por tres años para el ajuste del volumen de caldo a aplicar por hectárea en función del tamaño de los árboles aplicando la fórmula del TRV (“Tree Row Volume” en un lote de naranja Valencia (Citrus sinensis L. Osb. con alta incidencia de (MN. Los ensayos consistieron en la utilización de picos inyectores de aire ID instalados en turbinas de alto volumen con el fin de reducir el volumen total de caldo de modo similar al logrado con la tecnología de bajo volumen. Los resultadosobtenidos en diferentes campañas con picos ID en tratamientos reducidos al 50% en volumen ejercieron un muy buen control de la enfermedad sin diferencias significativas con respecto a los tratamientos de alto volumen convencionales. Esta estrategia permite optimizar la utilización de equipos existentes con el beneficiodel ahorro de agua, insumos y, además, sustentable con el ambiente.

    Los cítricos son un renglón importante en la agricultura colombiana ya que generan cerca de cincuenta mil empleos. Brevipalpus phoenicis es catalogado como el principal vector de la leprosis de los cítricos, enfermedad de carácter viral que causa pérdidas de sesenta millones de dólares al año en Brasil. En Colombia la enfermedad se reportó por el ICA para los departamentos de Meta y Casanare. Con el objetivo de determinar la distribución espacial del vector de la leprosis se realizó un muestreo de B. phoenicis semanal durante los meses de febrero a abril del año 2006 (12 muestreos en el tiempo en un cultivo de naranja Valencia en dos estratos del árbol (de 0 a 1,5 m y de 1,5 a 2,5 m de altura. Los datos se analizaron mediante una metodología geoestadística con el software Surfer 8 (Golden Software, 1997-2007 para determinar la distribución espacial del ácaro. Como resultado se obtuvieron 36 variogramas experimentales y 36 mapas de distribución espacial, para el periodo de duración del estudio. El ácaro tuvo un comportamiento inversamente proporcional a la precipitación ya que cuando comenzaron las lluvias su población disminuyó; así mismo el ácaro presentó un desplazamiento desde el estrato más húmedo del árbol hacia el más seco, lo que implica que el comportamiento del ácaro es dependiente tanto de la humedad relativa como de la precipitación. El patrón de distribución del ácaro se ajustó a un modelo lineal y se determinó la tendencia del vector hacia el costado más seco del lote.

    Full Text Available There has been a growing interest in the food industry and in preventive medicine to search for «natural antioxidants». Therefore the objetive of this study was to evaluate the antioxidant activity of the non-volatile residue of essential orange oil in the oxidation of unrefined and freshly extracted olive oil. Essential orange oil was distilled to obtain a non-volatile residue and fracctionated on a Silica Gel 60 column. The antioxidant activity was determined by measuring peroxide value obtained after heating olive oil at 70 °C for 48 h. Six compounds were isolated and purified, four of these had antioxidant activity, α-tocopherol and three methoxylated flavones were identified using spectroscopic methods. This study confirmed that non-volatile fractions of essential orange oil contain natural antioxidants diferent from α-tocopherol.

    Existe un creciente interés en la industria alimentaria y en la medicina preventiva por la búsqueda de «antioxidantes naturales», por lo que nos planteamos evaluar la actividad antioxidante del residuo no volátil del aceite esencial de naranja contra la oxidación del aceite de oliva sin retinar y de reciente extracción. Mediante destilación del aceite esencial de naranja se obtuvo el residuo no-volátil, el cual se fraccionó en columna de silica gel 60. La actividad antioxidante fue medida por el valor de peróxidos producidos por el aceite de oliva al provocar la oxidación por calentamiento a 70 °C durante 48 h. Se aislaron seis compuestos mediante HPLC preparativo de los cuales cuatro tuvieron actividad antioxidante. Usando métodos espectroscópicos se identificaron α-tocoferol y tres flavonas metoxiladas. Con este estudio se confirmó que la fracción no volátil del aceite esencial de naranja contiene antioxidantes naturales diferentes al α-tocoferol.

Las condiciones de operación utilizadas fueron: relación sólido/líquido 4 g/l, tamaño de partícula ??0,425 mm, concentración inicial de disolución de Cr(III 100 mg/l, tiempo de contacto 60 h y pH constante (4 y 5. Los modelos cinéticos escogidos para identificar el mecanismo de reacción del proceso de bioadsorción usando cáscara de naranja fueron: primer orden reversible, pseudo- segundoorden, Elovich y difusión intraparticular. Los resultados indican que la ecuación de Elovich proporciona mayor exactitud en el ajuste de los datos experimentales del equilibrio a este modelo cinético. La bondad del ajuste de los datos se realizó por regresión no-lineal utilizando como criterio la minimización de la función objeto suma de los cuadrados del error, SCE, haciendo uso de la herramienta matemática MATLAB.

    Full Text Available Objetivos: Describir los patrones de mortalidad, general y por causas específicas seleccionadas, en Valencia y Alicante; establecer las diferencias internas por distritos, y evaluar los cambios en la magnitud de estas desigualdades en el tiempo. Métodos: Las defunciones ocurridas en residentes en las ciudades de Valencia y Alicante durante los períodos 1990-1992 y 1996-1998 se asignaron a los distritos municipales de residencia. La comparación entre los períodos de estudio o entre ciudades se ha realizado a través del riesgo relativo estimado mediante regresión de Poisson. Se calculó la razón comparativa de mortalidad (RCM según los 17 grandes grupos de la Clasificación Internacional de Enfermedades (9.ª revisión. Por distritos se han calculado en cada período de estudio las tasas ajustadas por el método directo, la razón de mortalidad estandarizada (RME, la razón de años potenciales de vida perdida (RAPVP y la esperanza de vida al nacimiento. Resultados: Los riesgos de muerte por todas las causas disminuyen del primer al segundo período tanto en varones, como en mujeres en ambas ciudades. La esperanza de vida aumenta significativamente en ambas ciudades en los varones, y en Valencia en las mujeres. La ciudad de Valencia presenta un mayor riesgo de muerte en ambos períodos. Algunos grupos de causas de muerte aumentan (grupos 5 y 6, que incluyen trastornos mentales y enfermedades del sistema nervioso y órganos de los sentidos. Por distritos, se observa una mayor variabilidad en Valencia --donde destacan los distritos 1 y 11 con un elevado riesgo de mortalidad-- que en Alicante. Conclusiones: El proceso de vigilancia de la mortalidad interna, por distritos, es reproducible. En la ciudad de Valencia existen diferencias en la mortalidad que se mantienen en el tiempo. La ciudad de Alicante presenta una menor variabilidad interna en sus indicadores de mortalidad.Objectives: To describe mortality patterns, in general and by

    Full Text Available El objetivo de este trabajo, fue determinar la capacidad de remoción del colorante compuesto naranja remazol presente en aguas residuales textiles, utilizando el proceso de adsorción con carbón activado, con base en el pH y la concentración de colorante. La metodología involucró la preparación de muestras con concentraciones de 100 a 600 ppm de colorante a pH de 3, 7 y 9; la obtención de isotermas ajustadas a los modelos de Langmuir y Freundlich; y la determinación de la concentración del colorante a través de un espectrofotómetro UV-Vis. Los resultados indicaron una mejor eficiencia de remoción del colorante a pH 3, concluyendo que a mayor pH disminuye la capacidad de adsorción, debido principalmente a las interacciones electrostáticas que se generan entre la superficie del adsorbente y el colorante.

This one outlines a series of social. economic, urban and architectural objectives lo improve the quality of the residents' life and lo attract new neighbours, lo energize trade and associations and lo preserve the existent built heritage. The Plan RI VA is rewarded in 1998 such as one of the 100 Best Practices, as a complete performance in the old town of Valencia. It’s continuous development along the years goes configuring environments that can be defined as finished. With this appellative they define areas that have finish ed their physical rehabilitation and their social and economic regeneration. As upgrade of the Plan already presented, u intends now the result of one of those completed areas, which is the Moro Zeit Urban Axis. The great scale urban renovation began in 1996 in the centre of the Barrio de Velluters, in the scene of the European operative program URBAN. 11is now completed with the realization of the proposed area, as an important artery 01 connection of this quarter with the rest of the historical centre. The initiative has required the coordination of all the agents interveners, public and private, with periodic meetings of different work groups that have adjusted the final quantitative and qualitative parameters .En 1992 las Instituciones Públicas se plantean la recuperación del Centro Histórico de Valencia, con un importan le patrimonio edificado y algunos de sus barrios en una situación de profunda degradación social, económica y arquitectónica, mediante la firma de un Convenio entre el Ayuntamiento y la Generalitat Valenciana (RIVA, creando el Plan RIVA.

El jugo de naranja, se fermentó con Saccharomyces cer evisiae hasta 14 % v/v de alcohol. La bioxidación se realizó con Acetobacter sp., en cultivo sumergido, en biorreactor de laboratorio. Para evitar el efecto inhibidor del etanol sobre las bacterias acéticas, el vino de naranja fue diluido a 6 % v/v de alco hol con solución de minerales. La influencia de las variables se evaluó con diseño factorial 2 k . Se estudió caudal de aire/velocidad de agitación, ensayando los niveles 0.3 – 0.6 vvm y 200 - 400 rpm y luego, caudal de aire/temperatura, siendo los niveles para cada variable 0.4 – 0.6 vvm y 25 - 30 ºC, respectivamente. Cada tratamiento se realizó por duplicado, usando como respuestas productividad y rendimiento. El análisis del diseño (α<0.05 se efectuó mediante programa Statgraphics Centurion XV Corporate. En los tratamientos con 200 rpm y distintos caudales de aire, no hubo diferencias significativas respecto a la productividad. A mayor velocidad de agitación y caudal de aire, la productividad fue mayor. Los mayores rendimientos se obtuvieron con menores caudales de aire y mayores velocidades de agitación. Con respecto a la temperatura, los valores ensayados no presentaron diferenc ias significativas en las respuestas estudiadas. El mejor rendimiento se obtuvo con 400 rpm y 0.3 vvm a 25 ºC. Se concluye que la velocidad de agitación juega un rol muy importante para lograr una mejor productividad mientras que elevados flujos de aire d isminuyen el rendimiento.

    To obtain epidemiological data on the prevalence of the different types of Usher syndrome (US) in Spain, since these data were missing; to estimate the proportion of sporadic cases among simplex families, and calculate the prevalence of the Usher syndrome in a homogeneous population from Eastern Spain (3,875,234 inhabitants) that is representative of the Spanish population. Otological, ophthalmological and genetic studies were performed in 89 US patients from 46 families and subjected to statistical and segregation analysis. 41.6% of them suffered US type I, 46.1% type II, and in 12.3% the classification remains unclear. The estimated prevalence for the Province of Valencia was 4.2/100,000. There was a notable excess of male-only affected multiplex sibships in our sample that could be attributable to an X-linked inheritance. The number of families with USI type was similar to that of families with USII type. The estimated prevalence for the Province of Valencia is in agreement with other reports in which the estimate for the prevalence of US ranges from 1.8 to 6.2/100,000.

    There is no doubt in asserting that the Adaptation of the Valencia and its Country General Urban Management Paln to the South Settlementm, approved on June 30, 1966, has become one fo the most controversial and trascendental projects referred to the Valencia metropolitan urbanism. A reviled planning, often labeled as a developmentalist one, despite the fact taht any of its original documents was never published: specialized literature paid no attention to the intra-history, focusing instead in the sociopolitical reasons which led to its revocation. It could ultimately seem that no one wanted to ask the right questions, like how could it be possible that Greater Valencia Administrative Corporation architects (three of the main experts of their generation answered for such a supposedly calamitous Town Planning. Thus, in order to achieve right insight, it´s necessary to carefully analyze the wide period-eight decisive years-between the ministerial approval of the Special Technic Commision conclusions (July 22, 1958 and the finally adoption of the plan. Such is this paper´s aim, enabling a proper comprehension supported by the interesting and unpublished drawing up of its previous studies.

    Full Text Available This article is one of the first to raise the issue of Women in the Franco regime prisons, specifically in the region of Valencia. Historiography of the Franquoist repression, in particular in Valencia, has paid scarce attention to that topic. This study provides a research about the modus operandi of prisons and others buildings —such as the Santa Clara’s convent—, used in order to jail republican women. Some of them were sentenced to death, and their children taken away in a lot of cases. And all of them suffered subhuman living conditions. On the one hand, the text analyses the prison files as an example of the official repression discourse. On the other hand, it also deals with some of these women’s stories, testimonies and memories as an example of the anti-Franco resistance discourse.

    Purpose: High dose rate (HDR) brachytherapy for treatment of small skin lesions using the Leipzig and Valencia applicators is a widely used technique. These applicators are equipped with an attachable plastic cap to be placed during fraction delivery to ensure electronic equilibrium and to prevent secondary electrons from reaching the skin surface. The purpose of this study is to report on the dosimetric impact of the cap being absent during HDR fraction delivery, which has not been explored previously in the literature. Methods: GEANT4 Monte Carlo simulations (version 10.0) have been performed for the Leipzig and Valencia applicators with and without the plastic cap. In order to validate the Monte Carlo simulations, experimental measurements using radiochromic films have been done. Results: Dose absorbed within 1 mm of the skin surface increases by a factor of 1500% for the Leipzig applicators and of 180% for the Valencia applicators. Deeper than 1 mm, the overdosage flattens up to a 10% increase. Conclusions: Differences of treating with or without the plastic cap are significant. Users must check always that the plastic cap is in place before any treatment in order to avoid overdosage of the skin. Prior to skin HDR fraction delivery, the timeout checklist should include verification of the cap placement.

    Full Text Available We describe and characterize an exceptionally large HIV-1 subtype B transmission cluster occurring in the Comunidad Valenciana (CV, Spain. A total of 1806 HIV-1 protease-reverse transcriptase (PR/RT sequences from different patients were obtained in the CV between 2004 and 2014. After subtyping and generating a phylogenetic tree with additional HIV-1 subtype B sequences, a very large transmission cluster which included almost exclusively sequences from the CV was detected (n = 143 patients. This cluster was then validated and characterized with further maximum-likelihood phylogenetic analyses and Bayesian coalescent reconstructions. With these analyses, the CV cluster was delimited to 113 patients, predominately men who have sex with men (MSM. Although it was significantly located in the city of Valencia (n = 105, phylogenetic analyses suggested this cluster derives from a larger HIV lineage affecting other Spanish localities (n = 194. Coalescent analyses estimated its expansion in Valencia to have started between 1998 and 2004. From 2004 to 2009, members of this cluster represented only 1.46% of the HIV-1 subtype B samples studied in Valencia (n = 5/143, whereas from 2010 onwards its prevalence raised to 12.64% (n = 100/791. In conclusion, we have detected a very large transmission cluster in the CV where it has experienced a very fast growth in the recent years in the city of Valencia, thus contributing significantly to the HIV epidemic in this locality. Its transmission efficiency evidences shortcomings in HIV control measures in Spain and particularly in Valencia.

    Full Text Available The Inquisition in 1618 seized all the papers of Pedro de Valencia, renowned humanist, biblical scholar and chronicler of Philip III. The papers of other members of his circle were also confiscated. In this article I examine the two most important texts: Sobre el pergamino y láminas de Granada of Valencia and a Libelo Segundo of Francisco de Gurmendi, interpreter of Oriental languages for Philip III. The article is structured around Gurmendi's response to a memorial published in 1617 by Archbishop Pedro de Castro in defence of one of his translators. Gurmendi, working from his translation of the first two Lead Books, shows how these contain heretical ideas on the Trinity and how the memorialista has mistranslated many passages.

    En 1618 la Inquisición confiscó todos los papeles de Pedro de Valencia, humanista insigne, exegeta bíblico y cronista del reino y de las Indias de Felipe III.

    Extreme temperature events have a great impact on human society. Knowledge of minimum temperatures during winter is very useful for both the general public and organisations whose workers have to operate in the open, e.g. railways, roadways, tourism, etc. Moreover, winter minimum temperatures are considered a parameter of interest and concern since persistent cold-waves can affect areas as diverse as public health, energy consumption, etc. Thus, an accurate forecasting of these temperatures could help to predict cold-wave conditions and permit the implementation of strategies aimed at minimizing the negative effects that low temperatures have on human health. The aim of this work is to evaluate the skill of the RAMS model in determining daily minimum temperatures during winter over the Valencia Region. For this, we have used the real-time configuration of this model currently running at the CEAM Foundation. To carry out the model verification process, we have analysed not only the global behaviour of the model for the whole Valencia Region, but also its behaviour for the individual stations distributed within this area. The study has been performed for the winter forecast period from 1 December 2007 - 31 March 2008. The results obtained are encouraging and indicate a good agreement between the observed and simulated minimum temperatures. Moreover, the model captures quite well the temperatures in the extreme cold episodes. Acknowledgement.

    A study is made of the experience gained with the Child Oral Care Program (Plan de Atención Dental Infantil, PADI) in the Service of Stomatology of Valencia University General Hospital (Valencia, Spain) after four years in operation (July 2003 - July 2007). The sample comprised 2626 children between 5-14 years of age, pertaining to department 9 of the Valencian public health system. A clinical history was compiled in each case, a radiological study was made, and a treatment plan was elaborated including fillings, extractions, and control visits. Of the 2626 designated children, 2369 visited our Service - mostly referred from the Preventive Dental Care Units. A total of 5784 fillings were carried out (93.3% with silver amalgam, 5.6% with composites and the rest as provisional fillings). The permanent first molars were the teeth with the largest number of fillings (70.2% of the total). These were followed in order of frequency by the second molars (19.1%). As regards composite resin fillings, most involved the upper central incisors, followed by the upper lateral incisors. A total of 644 extractions were performed, corresponding to 110 permanent teeth and 534 temporary teeth. In the case of the permanent dentition, the first molars were the most commonly removed teeth. In the temporary dentition, the most frequently removed teeth were the second molars. The response of the population to this program has been very good, and reinforces the preventive measures already in place, with the provision of restorative treatments to improve the oral and dental health of the pediatric population, and yielding good results in terms of the program quality indicators. The Service of Stomatology (Valencia University General Hospital) is able to address the demand and offers the public health network integrated and continuous patient care.

Starting from this point, the Local and Self Governing Authorities signed, in 1998, an agreement in order to invest about 40.000 millions pesetas, amount who was increased with a country government 's help named "Planes de Vivienda" with the aim lo help the rehabilitation and the flats purchase. The combined action of different Governments and the promotion of the private initiative, was completed with the European help through FEDER funds, concerning the Operative Urban program in order lo recuperate the degradate districts. The collaboration of different Professional Associations, Architects College, Universities, Residents Associations, etc., was very important.

    Abstract: This work is a section of the author´s doctoral thesis, dedicated to the study of open block planning residential areas in the city of Valencia, in a period between 1946 and 1988. The two major planning landmarks in that period are the South Plan, approved in 1958, just a year after the great flood, that included the deviation of the Turia riverbed, and the Valencia and its Region General Plan adapted to South Solution, approved in 1966, that replaces the previous plan. This results in three stages, corresponding to the three sections into which the thesis is divided. The first stage between the General Plan of 1946 and the 1957 flood, which is the one contained in this publication, shows the gradual introduction in Valencia of open block planning principles, used initially in small scale public housing developments, and also in a series of plans and unrealized urban projects. In the second stage, between 1958 South Plan and 1966 General Plan, open planning states increasingly as typical growth form for urban periphery, while new planning principles are applied in a more elaborate way. The third stage, between 1966 General Plan and 1988 PGOU, which coincides with an economic expansion period and an accelerated building activity in peripheral areas, is characterized by the trivialization of such principles as a result of its routinary and simplistic implementation, which is one of the determinant factors in its later discredit.

    Failure to adopt a correct working posture can lead to occupational diseases. Evaluate knowledge in relation to ergonomics about BHOP concept and its application to routine clinical practice amongst undergraduate and postgraduate dental students in the University of Valencia (Valencia, Spain). A study based on interviews of undergraduate and postgraduate dental students in the University of Valencia (Valencia, Spain) was carried out. The information from a total of 336 interviews was used for the statistical analysis, differentiating according to gender and academic year: knowledge of ergonomics, pain prevalence and antecedents, assessment of the possible necessity for improved training in ergonomics, and evaluation of postural hygiene. Only 28.6% of the students were found to sit correctly in the dentist chair. Furthermore, in the opinion of the students, very few subjects during the career afforded adequate teaching in relation to ergonomics and working posture. The analysis of postural hygiene showed great variability. There were no significant differences in posture between males and females, although some incorrect postures appeared to be associated with the academic year (Ppostural hygiene were noted on progressing from one academic year to the next. The students in our study were not familiar with the principles of ergonomics and did not sit correctly in the dentist chair. Improved training in this field is required in dental school. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The presence of fossil or relict bedforms is common in the Quaternary fill of modern continental shelf due to sea level oscillations, tectonic subsidence and migration of associated sedimentary facies. The continental margin of the Gulf of Valencia has been strongly influenced by glacio-eustasy and neotectonics. High-resolution multibeam bathymetry data, seismic reflection profiles and box core samples were collected across the continental shelf of the Gulf of Valencia during the DERIVA cruises carried out in 2010 and 2011. The integrated analysis of this data set and high-resolution mapping of the relict bedforms on the Valencian continental shelf, ranging between 50 and 90 m allowed the study of previously identified system of sand waves located in front of the present-day Albufera de Valencia lagoon. The system is composed of 27 ridges with a NNE-SSW orientation, i.e. oblique to the present shoreline, in which the lateral horns point backwards. These sand waves can reach 10 m in height and 3 km in length resulting in a maximum slope of 6°. According to seismic stratigraphic and relative sea level curve reconstructions, these sand waves were formed during the Younger Dryas (~ 12-10 ky BP). Consequently, they have been classified as Holocene sand waves associated with coastal sedimentary evolution.

    Early instrumental series are the main source for climate information in the 18th and the first part of the 19th century, which is when systematic meteorological observations started in most national meteorological services. The first continuous series in Spain starts in 1780 in Barcelona due to meteorological observations made by the medical doctor Francisco Salvá Campillo. Moreover, only two other series have been recovered at the present in Spain: Madrid and Cádiz/San Fernando. Until present, in Spain the major part of the meteorological observations detected in early instrumental periods were made by medical doctors, who started to pay attention to the environmental factors influencing population health under the Hippocrates oath, although also there are military institutions and academic university staff (e.g. physicists, mathematicians, etc.). Due to the high spatial and temporal climate variability in the Iberian Peninsula, it is important to recover and digitize more climatic series, and this is one of the main goals of the Salvá-Sinobas project (http://salva-sinobas.uvigo.es/) funded by the Spanish Ministry of Environment, and Rural and Marine Affairs for the 2009-2011 period. The first new series with systematic observations was detected in the city of Valencia, in the eastern façade of the Iberian Peninsula. The meteorological observations were daily published in the newspapers Diario de Valencia (1804-1834) and Diario Mercantil de Valencia (1837-1863) until official meteorological observations started in 1858 at the University of Valencia. Each day 3-daily observations (morning, midday, afternoon) were published with five climatic variables: temperature, air pressure, humidity, wind direction and the sky state. Only during the 1804-1808 period daily rainfall data is available. We checked the observer comments published in the newspapers to obtain metadata about the instruments and meteorological station information. Unfortunately, temperature data

    To describe the prevalence of exposure to occupational risks among pregnant women and analyze its relationship with personal and occupational characteristics using information collected in the Childhood and Environment (Infancia y Medio Ambiente [INMA])-Valencia cohort study. The INMA-Valencia cohort study started in 2004 with 855 pregnant women living in Valencia, Spain. Data on sociodemographic variables (age, education and country of birth) and occupational conditions (activity, occupation, type of contract, working hours and self-reported occupational exposure to physical load and psychosocial, physical, chemical and biological risks) in women with paid employment during pregnancy (n=649) were collected through face-to-face interviews with a structured questionnaire in week 32 of pregnancy. The prevalences of reported exposure to physical and psychosocial load and to physical pollutants (including non-ionizing radiations) were 56%, 63% and 62%, respectively. The prevalence of reported exposure to chemicals (including cleaning products) and biological pollutants was 22% and 6%, respectively. In general, the characteristics most closely associated with exposure to occupational risks were younger age, non-Spanish nationality, lower education, having a temporary contract or being self-employed. This study is the first to quantify the prevalence of exposure to occupational risks during pregnancy in a Spanish population-based sample. According to the data observed, surveillance and control actions should be intensified in pregnant workers, as some of the observed occupational exposures have been consistently associated with detrimental reproductive and developmental effects.

    To estimate the short-term association between air pollution levels and emergency hospital admissions for cardiovascular diseases in Valencia, within 1994-1996 period. Daily levels of air pollution and emergency admissions for cardiovascular diseases were related to using an ecological time series design. The number of admissions was obtained from the hospital records database. Selected groups of causes were all cardiovascular diseases, heart admissions, and admissions for cerebrovascular diseases. The number of admissions for digestive diseases was used as control. Pollutants were black smoke, sulphur dioxide (SO(2)), nitrogen dioxide (NO(2)), carbon monoxide (CO) and ozone (O(3)). Magnitude of association was estimated by Poisson autoregressive regression. Estimations were calculated according the hottest (May to October) and the coldest (November to April) periods. City of Valencia, Spain, about 750,000 inhabitants. People being admitted to the two major hospitals in the city, with a catchment area of nearly 400,000 inhabitants. For the whole period, a significant association for SO(2)-24 h was found so a rise in its levels of 10 microg/m(3) was associated with an increment of 3% (95%CI 0.4 to 5.7%) in the expected number of cardiovascular admissions. A significant association for black smoke, SO(2)-24 h, SO(2)-1 h, and CO-1 h was found in the hottest semester. All these associations were verified with a lag of two days. The estimates of the associations for particles, SO(2), and CO were affected by the inclusion of the other pollutants in their models. NO(2) was independently associated with cerebrovascular admissions. There were no significant associations between air pollution and admissions for digestive diseases. Current levels of air pollution and emergency cardiovascular admissions are significantly related in Valencia.

    In recent years a study of the quality of the night sky in the surroundings of the metropolitan area of Valencia has been done. To achieve this, we used a Sky Quality Meter (SQM-LE) together with a GPS in order to cover a large number of routes from very bright locations near the city of Valencia to very dark areas located more than 100 kilometres away. The objectives of the study were to determine the variation of light pollution with respect to the distance to Valencia, locate areas with a high quality night sky in order to claim for their protection and verify the contribution of smaller towns in the brightness of the sky. Since light pollution also affects biodiversity, we have especially studied its influence on the night sky close to natural parks. Night routes have been done in the interior and vicinity of the Parc de la Calderona, the Albufera and especially the Parc del T ´uria. Our study concludes that these parks are completely degraded and need an urgent protection plan against light pollution. Finally, we present the first results of our fixed detectors SQM-LU scattered throughout the Valencian territory.

    Full Text Available The Valencia applicators (Nucletron, an Elekta company, Elekta AB, Stockholm, Sweden are cup-shaped tungsten applicators with a flattening filter used to collimate the radiation produced by a high-dose-rate (HDR 192 Ir source, and provide a homogeneous absorbed dose at a given depth. This beam quality provides a good option for the treatment of skin lesions at shallow depth (3-4 mm. The user must perform commissioning and periodic testing of these applicators to guarantee the proper and safe delivery of the intended absorbed dose, as recommended in the standards in radiation oncology. In this study, based on AAPM and GEC-ESTRO guidelines for brachytherapy units and our experience, a set of tests for the commissioning and periodic testing of the Valencia applicators is proposed. These include general considerations, verification of the manufacturer documentation and physical integrity, evaluation of the source-to-indexer distance and reproducibility, setting the library plan in the treatment planning system, evaluation of flatness and symmetry, absolute output and percentage depth dose verification, independent calculation of the treatment time, and visual inspection of the applicator before each treatment. For each test, the proposed methodology, equipment, frequency, expected results, and tolerance levels (when applicable are provided.

  19. Model Uncertainties for Valencia RPA Effect for MINERvA

    Energy Technology Data Exchange (ETDEWEB)

    Gran, Richard [Univ. of Minnesota, Duluth, MN (United States)

    2017-05-08

    This technical note describes the application of the Valencia RPA multi-nucleon effect and its uncertainty to QE reactions from the GENIE neutrino event generator. The analysis of MINERvA neutrino data in Rodrigues et al. PRL 116 071802 (2016) paper makes clear the need for an RPA suppression, especially at very low momentum and energy transfer. That published analysis does not constrain the magnitude of the effect; it only tests models with and without the effect against the data. Other MINERvA analyses need an expression of the model uncertainty in the RPA effect. A well-described uncertainty can be used for systematics for unfolding, for model errors in the analysis of non-QE samples, and as input for fitting exercises for model testing or constraining backgrounds. This prescription takes uncertainties on the parameters in the Valencia RPA model and adds a (not-as-tight) constraint from muon capture data. For MINERvA we apply it as a 2D ($q_0$,$q_3$) weight to GENIE events, in lieu of generating a full beyond-Fermi-gas quasielastic events. Because it is a weight, it can be applied to the generated and fully Geant4 simulated events used in analysis without a special GENIE sample. For some limited uses, it could be cast as a 1D $Q^2$ weight without much trouble.

    Preliminary analysis of data collected during the course of a cooperative Spanish-United States investigation of the Valencia Shelf (western Mediterranean) reveals a storm-dominated, mud-accumulating sedimentary regime. Calcareous mud is accumulating seaward of a narrow band of shoreface sand and gravel. On the outer shelf the mud is enriched by a pelagic calcareous component. Preliminary 210Pb data from vertical profiles of box cores yield nominal accumulation rates from 2.6 mm y -1 near the Ebro Delta to 1.3 mm y -1 on the southern portion of the Valencia Shelf. Storm-current winnowing has resulted in the development of a biogenic lag sand over the mid-shelf mud in the northern part of the study area. Piston cores reveal a basal Holocene sand and gravel facies similar to that presently seen on the inner shelf. Upward-fining sequences on the central and outer shelf are inferred to result from the landward shift of lithotopes during the course of the Holocene transgression. These sequences are locally repeated, perhaps as the consequence of brief, local interludes of coastal progradation. Application of a diagnostic circulation model suggests that intense, downwelling coastal flows occur during winter northeastern storms. Storm activity has induced erosional shoreface retreat during the course of the Holocene transgression and has generated by this means the basal coarse facies observed in the piston cores. In the central part of the study area seaward of the Albufera Lagoon, the mud blanket thins to a layer several centimeters thick which is draped over a thickened (10 m) basal sand. The basal sand is molded into northwest trending ridges. The data are not sufficient to determine whether these are overstepped barriers, or submarine sand ridges formed by storm flows during the shoreface retreat process.

    Purpose: In the commissioning and QA of surface isotope-based applicators, source-indexer distance (SID) has a great influence in the flatness, symmetry and output. To these purposes, methods described in the literature are the use of a special insert at the entrance of dwell chamber or radiochromic films. Here we present the experience with a micro-chamber array to perform the commissioning and QA of Valencia applicators. Methods: Valencia applicators have been used, the classic and the new extra-shielded version. A micro-chamber array has been employed, 1000 SRS (PTW), with 977 liquid filled, 2.3×2.3×0.5 mm{sup 3} sized ion chambers covering 11×11 cm{sup 2}, which spacing is 2.5 mm in the central 5.5×5.5 cm{sup 2}, dedicated mainly in principle, in conjunction with Octavius 4D (PTW), to IMRT, VMAT, SBRT verifications. Verisoft software that allows for 3D and planar analysis has been used to evaluate the results. Applicators were located on the surface of the array. To verify the SID, measurements corresponding to the reference value, SID ± 1 mm and SID ± 2 mm were acquired (integration time was fixed in order to discard the influence of the source entrance/exit). Once SID was determined, standard protocol treatments corresponding to 3 Gy and 7 Gy were acquired in order to establish typical patient dose distribution. Results: The method is fast and sensitive. The SID obtained was 1321 mm which is the nominal value included in the applicator manual. For example at 1319 mm an asymmetry of ±8% with respect to the central value was measured, along with a central deviation of −4% referred to 1321 mm. Conclusion: A practical method for the commissioning and QA of Valencia applicators has been described. It has been shown that it is an efficient and accurate tool for these purposes as well as for the verification of the absolute output constancy.

    In this study, we use a qualitative methodology to identify and compare factors of the built environment influencing the decision to walk for short trips in two different Spanish cities: Valencia and Granada. Three focus groups were held in Valencia and two in Granada with participants who undertook, at least once a week, one short non-shopping trip in any travel mode (were “short trip” is defined as less than 30-45 minutes walking distance). A thematic analysis of the data using the software QSR NVivo was performed after the transcription of the video recordings. Results show that participants perceive more facilitators to walking in Granada than in Valencia, explained by the smaller size of the former city and the driving restriction policy in the city centre of Granada for private cars. The main common barriers to walking in the two cities were: insecurity from crime (absence of people, a poor street lighting or walking along a conflictive are), a high density of traffic lights and walking along large avenues. In the city of Valencia, crossing multilane avenues and large-diameter roundabouts are deterrents to walking. In Granada, very steep streets motivate the use of alternative travel modes. (Author)

    2016-01-01

    Purpose: To determine the correction factor of the correspondence factor for the Standard Imaging IVB 1000 well chamber for commissioning of Elekta’s Leipzig and Valencia skin applicators. Methods: The Leipzig and Valencia applicators are designed to treat small skin lesions by collimating irradiation to the treatment area. Published output factors are used to calculate dose rates for clinical treatments. To validate onsite applicators, a correspondence factor (CFrev) is measured and compared to published values. The published CFrev is based on well chamber model SI HDR 1000 Plus. The CFrev is determined by correlating raw values of the source calibration setup (Rcal,raw) and values taken when each applicator is mounted on the same well chamber with an adapter (Rapp,raw). The CFrev is calculated by using the equation CFrev =Rapp,raw/Rcal,raw. The CFrev was measured for each applicator in both the SI HDR 1000 Plus and the SI IVB 1000. A correction factor, CFIVB for the SI IVB 1000 was determined by finding the ratio of CFrev (SI IVB 1000) and CFrev (SI HDR 1000 Plus). Results: The average correction factors at dwell position 1121 were found to be 1.073, 1.039, 1.209, 1.091, and 1.058 for the Valencia V2, Valencia V3, Leipzig H1, Leipzig H2, and Leipzig H3 respectively. There were no significant variations in the correction factor for dwell positions 1119 through 1121. Conclusion: By using the appropriate correction factor, the correspondence factors for the Leipzig and Valencia surface applicators can be validated with the Standard Imaging IVB 1000. This allows users to correlate their measurements with the Standard Imaging IVB 1000 to the published data. The correction factor is included in the equation for the CFrev as follows: CFrev= Rapp,raw/(CFIVB*Rcal,raw). Each individual applicator has its own correction factor, so care must be taken that the appropriate factor is used.

    This report evaluates the June 2008 onychomadesis outbreak in Valencia, Spain. The study sample consisted of 221 onychomadesis cases and 77 nonaffected individuals who lived close to those affected. We collected data on dietary variables, hygiene products, and individual pathological histories. Feces and blood specimens were collected from 44 cases and 24 controls to evaluate exposure to infectious agents. Pathological background data revealed a high frequency (61%) of hand, foot, and mouth disease among the onychomadesis cases. Coxsackievirus A10 was the most commonly detected enterovirus in both case and control groups (49%). Other enteroviruses such as coxsackieviruses A5, A6, A16, B1, and B3; echoviruses 3, 4, and 9; and enterovirus 71 were present in low frequencies in the case and control groups (3-9%). The 2008 onychomadesis outbreak in the metropolitan area of Valencia was associated with an outbreak of hand, foot, and mouth disease primarily caused by coxsackievirus A10. © 2010 Wiley Periodicals, Inc.

    Despite the potential risks of drug use during pregnancy, consumption has increased in recent decades. To identify the risk of congenital anomalies (CA) associated with the use of drugs in primary care in pregnant women residents in the Valencia Region. A case-control study, considering a case as a less than one year old live birth in 2009-2010, diagnosed with a CA and resident in the Valencia Region, obtained from the CA population-based registry. Controls were selected from the Metabolic Disease Registry, and the drugs prescribed and dispensed from the Integral Management of Pharmaceutical Services. Crude odds ratio (OR) was calculated with its 95% confidence intervals and adjusted OR was calculated using logistic regression. A total of 1,913 cases and 3,826 controls were identified. The most frequently used drug groups were those acting on the musculoskeletal, nervous and respiratory systems, on the blood and blood forming organs, and anti-infection drugs. The most common drugs used were ibuprofen, dexketoprofen, paracetamol, amoxicillin, ferrous sulphate, and a combination of folic acid. A significantly increased risk of CA was identified for drugs acting on the musculoskeletal system (adjusted OR 1.14 [95% confidence interval 1.02-1.28]). A significantly decreased risk was observed for drugs acting on the blood and blood forming organs (adjusted OR 0.87 [95% confidence interval 0.78-0.98]). Associations between drugs and CA in pregnant women resident in the Valencia Region have been identified for drugs that act as risk factors of CA, and for drugs that act as protective factors of CA.

    Full Text Available Volatiles from huanglongbing (HLB symptomatic and asymptomatic cold pressed orange oils from Florida Hamlin and Valencia fruit were assessed. Qualitative gas-liquid chromatography studies showed the presence of several compounds (β-longifolene, perillene, and 4-decenal which are not commonly identified in Citrus sinensis (L. Osbeck oils. Oils derived from huanglongbing symptomatic fruit had lower concentrations of linalool, decanal, citronellol, neral, geranial, carvone, dodecanal, and 2-decenal and higher concentrations of citronellal compared to asymptomatic fruit. A comparison to historic literature of orange oil investigations before HLB was of issue in Florida orange crops showed lower levels of linalool, decanal, neral, and geranial in Hamlin peel oil samples, as well as higher levels of dodecanal. Valencia peel oil samples showed lower concentrations of linalool and increased concentration of citronellol and dodecanal. As a result of huanglongbing (HLB phenomena, the concentrations of several important volatiles found in Hamlin and Valencia peel oil profiles have changed compared to historic values. Differences in volatile concentrations of symptomatic and asymptomatic HLB affected peel oil compounds in orange fruit are identified.

    Purpose: Utilization of HDR brachytherapy treatment of skin lesions using collimated applicators, such as the Valencia or Leipzig is increasing. These applicators are made of cup-shaped tungsten material in order to focalize the radiation into the lesion and to protect nearby tissues. These applicators have an attachable plastic cap that removes secondary electrons generated in the applicator and flattens the treatment surface. The purpose of this study is to examine the dosimetric impact of this cap, and the effect if the cap is not placed during the HDR fraction delivery. Methods: Monte Carlo simulations have been done using the code Geant4 for the Valencia and Leipzig applicators. Dose rate distributions have been obtained for the applicators with and without the plastic cap. An experimental study using EBT3 radiochromic film has been realized in order to verify the Monte Carlo results. Results: The Monte Carlo simulations show that absorbed dose in the first millimeter of skin can increase up to 180% for the Valencia applicator if the plastic cap is absent and up to 1500% for the Leipzig applicators. At deeper distances the increase of dose is smaller being about 10–15%. Conclusion: Important differences have been found if the plastic cap of the applicators is absent in the treatment producing an overdosage in the skin. The user should have a checklist to remind him check always before HDR fraction delivery to insure the plastic cap is placed on the applicator. This work was supported in part by Generalitat Valenciana under Project PROMETEOII/2013/010, by the Spanish Government under Project No. FIS2013-42156, and by a research agreement with Elekta Brachytherapy, Veenendaal, The Netherlands.

    As a consequence of the 26 April 1986 accident at the Chernobyl nuclear plant, a large amount of radioactivity was released into the atmosphere. The radioactive plume formed could be detected in practically the whole of the Northern Hemisphere a few days later. The zone most affected by the radioactive cloud over Spain was that of the Mediterranean coast and the Balearic Islands. In this paper, the authors examine the level of the radioactive contamination reached in various receptive media in Valencia, such as air, dry-fallout, water, soil, grass and milk samples collected in Valencia immediately after the accident. The activity levels are compared with those found during 1964 and 1965 due to the Chinese nuclear atmospheric explosions. The levels of contamination presented by four species of migratory birds which spend the winter in this area is analyzed. Lastly, an estimate is made of the absorbed dose

    To estimate consumption of five subgroups of antihypertensive drugs by primary care areas and to analyze its variation. We performed an ecological, descriptive study of antihypertensive consumption in 239 primary care areas in the autonomous region of Valencia in 2005 followed by analysis of the variability observed. The 239 primary care areas were studied by descriptive analysis of dispensation [defined daily dose (DDD) per 1,000 inhabitants/day in pensioners (DDD/1000p/day) and in the active population (DDD/1000a/day)] and standardized consumption ratios. Small-area variation analysis was used to analyze the observed variability. Associations among dispensations of the distinct therapeutic subgroups were also analyzed. Overall antihypertensive use in the autonomous region of Valencia in 2005 was 235.6DDD/1000/day. This consumption was concentrated in pensioners (800DDD/1000p/day vs. 73DDD/1000a/day). Consumption of antihypertensive subgroups oscillated from 442DDD/1000p/day for drugs with action on the renin-angiotensin system to 32DDD/1000p/day for doxazosin. The active population showed similar patterns. Variation in consumption was moderate, with coefficients of variation from 0.20 to 0.40 (slightly greater for the active population). Associations among dispensations of the different therapeutic subgroups were strong. This study shows major variations in the overall consumption of antihypertensive drugs among primary care areas of the autonomous region of Valencia. These results suggest that variation may be associated with problems of underutilization in areas with lower consumption. Copyright © 2010 SESPAS. Published by Elsevier Espana. All rights reserved.

    The ATLAS Tier-3 at IFIC-Valencia is attached to a Tier-2 that has 50% of the Spanish Federated Tier-2 resources. In its design, the Tier-3 includes a GRID-aware part that shares some of the features of IFIC Tier-2 such as using Lustre as a file system. ATLAS users, 70% of IFIC users, also have the possibility of analysing data with a PROOF farm and storing them locally. In this contribution we discuss the design of the analysis facility as well as the monitoring tools we use to control and improve its performance. We also comment on how the recent changes in the ATLAS computing GRID model affect IFIC. Finally, how this complex system can coexist with the other scientific applications running at IFIC (non-ATLAS users) is presented.

    The American red crayfish Procambarus clarkii, originally from Louisiana (USA) was introduced in Spain in the 70's in the Guadalquivir River swamps. It appeared first randomly and in a more regular basis afterwards since 1978 in the Albufera Lake south of Valencia and in the surrounding rice fields. Albufera lake and surrounding rice fields waters are being subject since the last three decades to very heavy load of sewage, toxic industrial residues including heavy metals and pesticides from the many urban and industrial settlements in the zone. In the present study, the authors have investigated the effect that heavy metals (Chromium, Cadmium and Mercury) have on the oxygen uptake by excised bills of Procambarus clarkii (Girard) coming from the Albufera Lake (Valencia).

  18. Smos Land Product Validation Activities at the Valencia Anchor Station

    Lopez-Baeza, Ernesto

    ABSTRACT Soil moisture is a key parameter controlling the exchanges between the land surface and the atmosphere. In spite of being important for weather and climate modeling, this parameter is not well observed at a global scale. The SMOS (Soil Moisture and Ocean Salinity) Mission was designed by the European Space Agency (ESA) to measure soil moisture over continental surfaces as well as surface salinity over the oceans. Since 2001, the Valencia Anchor Station is currently being prepared for the validation of SMOS land products, namely soil moisture content and vegetation water content. The site has recently been selected by the Mission as a core validation site, mainly due to the reasonable homogeneous characteristics of the area which make it appropriate to undertake the validation of SMOS Level 2 land products during the Mission Commissioning Phase, before attempting more complex areas. Close to SMOS launch, ESA has defined and designed a SMOS V alidation Rehearsal C ampaign P lan which purpose is to repeat the Commissioning Phase execution with all centers, all tools, all participants, all structures, all data available, assuming all tools and structures are ready and trying to produce as close as possible the post-launch conditions. The aim is to test the readiness, the ensemble coordination and the speed of operations, and to avoid as far as possible any unexpected deficiencies of the plan and procedure during the real C ommissioning P hase campaigns. For the rehearsal activity, a control area of 10 x 10 km2 has been chosen at the Valencia Anchor Station study area where a network of ground soil moisture measuring stations is being set up based on the definition of homogeneous physio-hydrological units, attending to climatic, soil type, lithology, geology, elevation, slope and vegetation cover conditions. These stations are linked via a wireless communication system to a master post accessible via internet. The ground soil moisture stations will also be used

  19. Soil erosion after forest fires in the Valencia region

    Science.gov (United States)

    2014-05-01

    Soil erosion after forest fire is triggered by the lack of vegetation cover and the degradation of the physical, biological and chemical properties (Martí et al., 2012; Fernández et al., 2012; Guénon, 2013). Valencia region belongs to the west Mediterranean basin ("Csa", Köppen climate classification), with drought summer periods that enhance forest fire risk. The characteristics of the climate, lithology and land use history makes this region more vulnerable to soil erosion. In this area, fire recurrence is being increased since late 50s (Pausas, 2004) and post-fire erosion studies became more popular from 80's until nowadays (Cerdá and Mataix-Solera, 2009). Research in Valencia region has contributed significantly to a better understanding of the effect of spatial and temporal scale on runoff and sediment yield measurements. The main achievements concerns: a) direct measurement of erosion rates under a wide range of methodologies (natural vs simulated rainfall, open vs closed plots); from micro- to meso-plot and catchment scale in single (Rubio et al., 1994; Cerdà et al., 1995; Cerdà 1998a; 1998b; Llovet et al., 1998; Cerdà, 2001; Calvo-Cases et al., 2003; Andreu et al., 2001; Mayor et al., 2007; Cerdà and Doerr, 2008) and multiples fires (Campo et al., 2006; González-Pelayo et al., 2010a). Changes in soil properties (Sanroque et al., 1985; Rubio et al., 1997; Boix-Fayós, 1997; Gimeno-Garcia et al., 2000; Guerrero et al., 2001; Mataix-Solera et al., 2004; González-Pelayo et al., 2006; Arcenegui et al., 2008; Campo et al., 2008; Bodí et al., 2012), in post-fire vegetation patterns (Gimeno-García et al., 2007) and, studies on mitigation strategies (Bautista et al., 1996; Abad et al., 2000). b) Progress to understanding post-fire erosion mechanism and sediment movement (Boix-Fayós et al., 2005) by definition of thresholds for sediment losses; fire severity, slope angle, bedrock, rain characteristics, vegetation pattern and ecosystem resilience (Mayor

    The present-day compartmented Mediterranean physiography is inherited from the last 250 Ma kinematic plate evolution (Eurasian, Africa, Iberic and Nubia plates) which implied the formation of orogenic chains, polyphased basins, and morphological - geodynamic thresholds. The interactions between these entities are strongly debated in the North-Western Mediterranean area. Several Neogene reconstructions have been proposed for the Valencia basin depending of the basin segmentation where each model imply a different subsidence, sedimentary, and palaeo-environmental evolution. Our study propose a new kinematic model for the Valencia Basin (VB) that encompasses the sedimentary infill, vertical movement and basin segmentation. Detailed analyses of seismic profiles and boreholes in the VB reveal a differentiated basin, the Minorca Basin (MB), lying between the old Mesozoic Valencia Basin sensu strico (VBss) and the young Oligocene Liguro-Provencal Basin (LPB) (Pellen et al., 2016). The relationship between these basins is shown through the correlation of four Miocene-to-present-day megasequences. The Central and North Balearic Fracture Zones (CFZ and NBFZ) that border the MB represent two morphological and geodynamical thresholds that created an accommodation in steps between the three domains. Little to no horizontal Neogene movements have been found for the Ibiza and Majorca Islands and imply a vertical "sag" subsidence. In contrast, the counterclockwise movement of the Corso-Sardinian blocks induced a counterclockwise movement of the Minorca block towards the SE along the CFZ and NBFZ, during the exhumation of lower continental crust in the LPB. The South-Eastward Minorca block translation stops when the first atypical oceanic crust occurs. The influence of the Neogene Betic compressional phase is thus limited to the VBss on the basis of a different MB origin. This new understanding places the AlKaPeCa blocks northeastward of the present-day Alboran Area. Both NW-SE and

    Full Text Available Polyphagotarsonemus latus is one a major pest of Valencia orange in Colombia. To study its biology, it was established an experiment on young leaves of the Valencia orange at 25 ± 5°C, 70 ± 5% RH, and 12:12 L:D photoperiod. To characterize the nature of damage caused by this mite on leaves and young fruits, a trial in screenhouse conditions using young leaf and small fruits (0.1 - 0.3 cm in diameter and fruits between 1.0–3.0 cm in diameter, which were infested with 5, 15 and 30 adult females of P. latus, was established. The total duration of life cycle was 3.2 days; the female had an oviposition period of 7.4 days and longevity 9.6 days. Life table parameters were as follows: net reproductive rate (Ro = 93.3, intrinsic rate of natural increase (rm = 1.2, finite multiplication rate (λ = 3.7, doubling time (TD = 0.6 days and generation time (T = 3.4. The first signs of damage and shoot drop in newly developed shoots occurred between 7.0 and 11.8 days after infestation. Small fruit infested with 5-30 mites showed damage 2.4 days after infestation. Shoot drop started 7.0 days after infestation. In the case of fruits between 1.0 and 3.0 cm in diameter, the damage and the collapse of the structure was between 3.0 and 13.5 days, respectively. These results explain how a mite with a very short life cycle and huge biotic potential causes such severe damage in shoots and newly formed fruits of Valencia orange.

    Somatic embryogenetic capability and changes in polyamine level and their relationship were analyzed using the long-term (8 years) subcultured calli of Citrus sinensis Osb. cv. Valencia as materials. The results showed that endogenous polyamine contents in embryogenic calli were higher than those in non-embryogenic calli, and the embryogenetic capability was positively correlated to the levels of endogenous polyamines. When the calli were transferred to a differentiation medium, the putrescine content rapidly increased and reached a peak, then fell gradually. Applying exogenous putrescine raised the embryogenesis frequency and endogenous putrescine level. It indicated that increase in putrescine content at early stage of differentiation promoted embryogenesis. With the development of somatic embryo, spermidine content reached its the highest level at globular embryo stage, spermine content rose and reached a peak at a later stage of globular embryo development. Furthermore, changes of the putrescine, spermidine and spermine contents during somatic embryogenesis were similar in Valencia calli which had different ploidy levels, but their contents decreased following the increasing of ploidy level. Changes in arginine decarboxylase activity were positively correlated to the polyamine levels, which suggest that the later is a key factor in regulating the polyamine levels during somatic embryogenesis in citrus plants.

    The focus of this study is the analysis of coastal sand barriers and associated coastal lagoons on the inner continental shelf of the Gulf of Valencia (western Mediterranean), based on two W-E seismic profiles recorded seaward of the Albufera de Valencia coastal lagoon. Seismic facies identified include a number of coastal sand barriers with landward lagoons draped by contemporary continental shelf deposits. The barrier systems have been grouped into two sedimentary systems tracts, the older one corresponding to a prograding/aggrading highstand systems tract involving at least four paleo-coastal sand barrier/lagoon systems, followed landward by a transgressive systems tract comprising three such systems. All the systems have been allocated a Tyrrhenian age, the formation of individual barrier systems having been associated with successive sea-level stillstands, and their present-day position being explained by the very high regional subsidence rate. In summary, this study demonstrates that the Quaternary stratigraphic record of the Gulf of Valencia inner continental shelf is composed of littoral sand facies, in particular coastal sand barrier and lagoon deposits. These findings are in agreement with corresponding observations on other continental shelves of the western Mediterranean, showing that the formation of coastal sand barriers was a characteristic feature of this region during the Quaternary.

    The introduction of conjugated anti-pneumonia vaccines has led to a change in the epidemiology of Invasive Pneumococcal Disease (IPD). The aim of this study is to describe the trends in IPD in the Community of Valencia during the period 2007-2012. A retrospective, descriptive and longitudinal study was conducted on IPD in the Community of Valencia during the period 2007-2012, The information sources used were the Epidemiological Surveillance Analysis (Análisis de la Vigilancia Epidemiológica (AVE)) and the Valencian Microbiology Network (Red Microbiológica Valenciana (RedMIVA)) of the Valencia Health Department. The incidence of IPD decreased between 2007 and 2012 in all age groups, mainly in the under 5 year-olds, dropping from 30.5 cases to 12.3 cases per 10(5) inhabitants (p< .001). Pneumonia was the principal presentation of the disease, with a decrease in its rates from 6.9 to 4.1 cases per 10(5) inhabitants (p< .001). A gradual, non-significant, reduction from 26% to 12% (p=.23) was observed in the proportion of cases due to the serotypes contained in the heptavalent vaccine (PCV7), mainly in the under 5 year-olds. The cases due to additional serotypes in 13-valent conjugated vaccine (1, 3, 5, 6A, 7F and 19A) also showed a decreasing trend, mainly in vaccinated under 5 year-olds (52.6% vs 14.3%; p=.03), while the cases due to non-vaccine serotypes significantly increased from 42.3% to 56.7% in the general population (p=.002), and from 47.4% to 78.6% in vaccinated under 5 year-olds (p=.08). The results of this study show a reduction in the incidence of IPD, with a decrease in the proportion of cases produced by vaccine serotypes, and an increase in the proportion of those not vaccinated. Epidemiological Surveillance is necessary to monitor the trends in the disease. Copyright © 2014 Elsevier España, S.L.U. y Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

    Avoidable mortality (AM) has been proposed as the indicator of the quality and the efficacy of health care services and a parameter useful to distribute health care resources. The aim of this study was to analyze the size and geographic variability of AM in the Community of Valencia, Spain (1975-1990). The causes of AM were analyzed by the classification of Holland divided into indicators of medical care (IMC) and indicators on national health care policy (INHCP) in addition to the causes of the Charlton classification. Standard rates for Spain and the European Community, the rate of masculinity and contribution to total mortality were calculated. Geographic distribution by areas and provinces was analyzed by the rate of standardized mortality. According to the Holland classification AM was 30% of the deaths from 5 to 64 years of age. Out of these cases, 18.5% corresponded to INHCP and 11.1% to IMC. According to the Charlton classification, this percentage was 3.6%. A considerable variation was observed among the 20 areas analyzed due to many causes. The geographic distribution by groups (IMC, INHCP and the Charlton classification) is quite homogeneous. The worse results corresponded to the city of Valencia and to the area 21 (area of the city of Alicante). A great variation was found in the results regarding geographic distribution for individual causes of death while the distribution was quite homogeneous for all of the groups of mortality with the worst results being observed in large urban centers.

    Full Text Available El alto contenido de humedad de la mena laterítica provoca su adherencia a las paredes de las tolvas donde es almacenada y, por consiguiente, disminuye la cantidad alimentada a los secaderos e incrementa el consumo de combustible durante el secado térmico en los tambores rotarios. Para evaluar el comportamiento de la adherencia en menas sometidas a secado solar natural se estudiaron experimentalmente dos pilas expuestas a condiciones ambientales naturales. Los experimentos consistieron en verter (para valores conocidos de humedad 300 g de mena desde una altura de 0,5 m sobre una placa de cristal con distinta inclinación (20 y 25 grados. Se tamizaron las muestras de una de las pilas para evaluar la influencia de la granulometría sobre la adherencia. Se encontró que la adherencia de la mena no está determinada solamente por el contenido de humedad, sino además por su granulometría y por el ángulo de inclinación de la superficie de contacto. El menor porcentaje de adherencia para granulometría heterogénea se obtuvo para valores de humedad igual o inferior a 32%. También se evidenció que para contenido de humedad igual a 35% o mayor, el ángulo de inclinación de la superficie de contacto con la mena no influye notablemente en la adherencia cuando la mena es previamente tamizada.

The population covered by the 59 doctors of the Health Sentinel Network constitutes 2.2% of the adult population of the Region of Valencia, and it is representative of it. Demographic, socioeconomic and health data as well as information concerning OAT. Quality of OAT management with VKA was assessed by means of the percentage of time in therapeutic range (TTR), computed using the Rosendaal method. A total of 1,144 patients were recorded (mean age 74.5±11 years; 49.7% women). Prevalence of OAT in the Region of Valencia is 1.3 cases per 100 population. The characteristic profile of these patients is an old person, with several comorbidities and a low level of education, who lives accompanied. Atrial fibrillation is the most common indication. 82.8% of patients on OAT with VKA were monitored in primary healthcare. The average TTR was 65.0%, and 53.9% of patients had a TTR ≥65%. Among inadequately controlled patients, 74.4% were perceived as well-controlled by their primary care doctor. Prevalence of OAT is high, and it is expected to increase. The degree of control achieved meets the generally accepted quality standard (mean TTR ≥65%), and it is comparable to that observed in other national and international studies. However, there is wide scope for improvement. It is crucial to optimize the management of this therapy in the most effective and cost-effective way.

    Valencia sweet orange (Citrus sinensis (L.) Osbeck) calluses were used as explants to develop a new transformation system for citrus mediated by Agrobacterium tumefaciens. Factors affecting Agrobacterium-mediated transformation efficiency included mode of pre-cultivation, temperature of cocultivation and presence of acetosyringone (AS). The highest transformation efficiency was obtained with a 4-day pre-cultivation period in liquid medium. Transformation efficiency was higher when cocultivation was performed for 3 days at 19 degrees C than at 23 or 28 degrees C. Almost no resistant callus was obtained if the cocultivation medium lacked AS. The transformation procedure yielded transgenic Valencia plants containing the pTA29-barnase gene, as verified by PCR amplification and confirmed by Southern blotting. Because male sterility is a common factor leading to seedlessness in citrus cultivars with parthenocarpic characteristics, production of seedless citrus genotypes by Agrobacterium-mediated genetic transformation is a promising alternative to conventional breeding methods.

    Full Text Available This paper presents data from research conducted at the University of Valencia in order to analyse students' perception on teaching competences of teachers in the area of Social and legal Sciences. The study included a total of 389 university students from 10 different degrees of the University of Valencia. In general, the subjects in the sample rated the 32 competencies as very important in the teaching / learning process. Students assess personal skills as the most important competences, followed by scientific, methodological and social ones.Overall the two most valued competences refer to “the proper and respectful treatment of students”, as well as “creating a classroom atmosphere based on dialogue and communication”. This data is a constant that is repeated in all degrees tested, with minor variations. The competences which are less valued are "Maintaining a careful personal image" and "keep update on new information and communication technologies”.

    Full Text Available Postulates on the tertiary age of humanity by some late-19th century evolutionists gave rise to heated controversy among naturalists, biologists and physicians. In Spain, the diatribes between supporters and detractors must be located within the general context of the evolutionary subject in a country, that was deeply polarized by ideological impregnations. Spanish debate was specially motivated by the arrival in Valencia of a human skeleton fossil in 1889. This specimen, collected in Argentina, showed some peculiar traits that were classified as primitive and dating from the Tertiary time period. During the early decades of 20th century, a series of papers about that skeleton were published and the controversy was reactivated. On one side, we find Eduardo Boscá, natural history professor in the University of Valencia, as a partisan of Tertiary age; on the other, the physician Faustino Barberá and some Jesuit scientists. Scientific data and ideological and religious arguments were combined in the defence of each confronted view.

    El postulado por parte de algunos evolucionistas de finales del siglo XIX acerca de la antigüedad terciaria de la humanidad suscitó intensas polémicas entre naturalistas, biólogos y médicos. En España también hubo adherentes y detractores, cuyas diatribas entraban en el contexto general de la cuestión evolucionista en nuestro país. El debate se animó especialmente a raíz de la llegada a Valencia, en 1889, de un esqueleto humano fósil procedente de la Argentina al que se le atribuyeron rasgos primitivos y una gran antigüedad. A comienzos del siglo XX, una serie de publicaciones sobre dicho ejemplar reactivaron la polémica, con el catedrático de la Universidad de Valencia, Eduardo Boscá, como partidario de la atribución de edad terciaria, y con el antagonismo destacado ante tal propuesta del médico Faustino Barberá y de diversos científicos jesuitas.

    Full Text Available During the 18th century the land surveying knew in Spain an unfinished process of institutionalizacion that laid the foundations of its further development. This process, which began in the ancient Reign of Valencia, provoked the successive aparition of local employment and the academic title of land-surveyor. The present work is focused on the circumstances wich took place in this process, as well as its limitations.

    The aim of this study was to valorize orange (Citrus sinensis) seeds, which are generated as waste. This study presents data about raw orange seed, the meal gained after cold pressing, and characterization data of the cold pressed seed oils. Furthermore, the effects of microwave roasting of the seds compared to regular roasting (control) were determined. The oil yield of orange seed cold pressing was around 52.93–62.99%. After cold pressing, 13.57–17.97% oil remained in the meal together with 20.68–25.61% protein. Hence, pressed meals could be valorized for different purposes. Except for turbidity, the color b* value, free acidity, the p-anisidine value and antioxidant capacity, there was no significant difference between the two oil samples for the measured physicochemical properties. Six different fatty acids were quantified and the major fatty acids were linoleic, palmitic and oleic acids. The fatty acid composition of the orange seed oil can be accepted as nutritionally balanced. Among the fifteen sterols quantified, β-sitosterol was dominant (around 77–78%). Likewise, the α-tocopherol content of the samples was not significantly different. The thermal onset and peak temperatures, and enthalpies for crystallization and melting were also reported. This study showed that good quality orange seed oils can be produced by cold pressing, and the oils could be used in food and non-food applications.

    2015-06-01

    Full Text Available The work of the humanist Pedro de Valencia belongs to “biblical humanism”. Religion and politics are inseparable in the work of this author. In the sixteenth century, a part of the population in Spain still subscribed to Jewish or Islamic thought. The Spanish church was making a huge effort at the time to integrate within the traditional Catholicism converts from these two communities. In this conflict the justifications of religious identity in various writings of Pedro de Valencia can be located. The common denominator of the writings discussed is summarized in the idea of religious unity of Conversos and Moriscos under the authority of the king in response to the conflicts in the Spain of the time.La obra del humanista Pedro de Valencia pertenece al «humanismo biblista». Religión y política son inseparables en este autor. En la España del siglo XVI existía todavía una parte de la población que pensaba en clave judía o bien en clave islámica. La iglesia española del momento estaba haciendo un esfuerzo enorme por integrar dentro del catolicismo tradicional a los conversos de estas dos comunidades. En este conflicto se enmarcan las justificaciones de la identidad religiosa en varios escritos de Pedro de Valencia. El común denominador de los escritos comentados se resume en la idea de la unidad religiosa de judeoconversos y moriscos bajo la autoridad del rey como respuesta a los conflictos de la España de la época.

    Full Text Available The present article analyzes some of the religious implications deriving from the famous controversy about the legality or illegality of theatre in the 17th century and in the city of Valencia. The question arose from an episode in which Don Luis Crespi de Borja was directly implicated. Crespi was the founder of the Oratory of Saint Philip Neri in the Valencian region and a persistent fighter against comedy. As a consequence of his position in this affair members of the Oratory were pursued by other ecclesiastical sectors favouring theatre.

    The effects of NPK fertilization on the nutrient concentration in the leaves was evaluated in a field experiment of Valencia orange (Citrus sinensis Osbeck) growing in a sandy acid soil, with 4N, 3P and 4K fertilizer levels. N and Cu contents in the leaves were high, while P and Zn levels were low, in all treatments. Increasing the levels of N, P 2 O 5 and K 2 O fertilization resulted in an increase of the N, P and K concentration in the leaves, respectively. Crescent levels of N fertilization raised Mn and decreased Ca concentration in the leaves. P and K contents in the leaves correlated positively. With a great availability and absorption of K, reduction on he foliar contents of Mg and Ca ocurred. (M.A.C.) [pt

    Full Text Available The effects of carnauba-based wax on the quality of 'Delta Valencia' orange produced in Ceará state, Brazil, were studied. The fruits were coated with carnauba-based wax and refrigerated (7 ± 2 ºC and 85 ± 2% R.H. for 28 days. The quality attribute parameters assessed were weight loss, peel color (brightness, hue angle, and chromaticity, peel moisture, pH, soluble solids (SS, titratable acidity (TA, SS/TA ratio, ascorbic acid, total soluble sugars, reducing sugars, yellow flavonoids, and polyphenols. The results showed that 'Delta Valencia' oranges grown in the dry climate of Ceará state has excellent quality. The coated fruits lost mass at a lower rate than the the control fruits. No significant loss of soluble solids, titratable acidity, pH, and SS/TA ratio was observed, while ascorbic acid, soluble sugars, reducing sugars, yellow flavonoids, and polyphenols increased during storage in both the coated and control fruits. Carnauba-based wax coated fruits showed no signal of dehydration keeping their shiny green peel up to the end of the storage. The use of coating was crucial for the maintenance of visual quality by reducing mass loss, as well as keeping peel moisture.

The testification of our writer before the Justicia Criminal court stands out among the news; it offers novelties about a young Valencian fisherman, allegedly murdered by several Majorcan men, prisoners at the time in Valencia. The fisherman was captive and alive in Algiers according to the testification. This piece of news was conveyed to several Majorcan merchants that claimed that the alleged murderers were innocent. All this resulted in a famous bet being placed in which huge amounts of money were bet upon whether Jeroni Planelles (as was named the mentioned fisherman was alive or dead. These documents also show the dealings had by Cervantes with the captives in Algiers (he wrote letters for them and with the merchants and rescuers (he gave them information about the captives location to be used later for their liberation. They also show some sources of income of Cervantes. It is revealed a lie told by our writer as well. And finally it is brought to light the oldest known autograph signature of Cervantes.

    Full Text Available RESUMEN: La génesis de las fronteras de los reinos cristianos medievales en España tiene mucho que ver con los procesos de guerra y conquista frente a al-Andalus. Éste es el caso del reino de Valencia, creado por el rey Jaime I en el año 1240 a partir de varios territorios musulmanes. Sus fronteras exteriores se crearon a partir de los límites entre cristianos y musulmanes en aquel momento y también por los pactos políticos con la corona de Castilla repartiéndose el territorio de al-Andalus. Pero estas fronteras no fueron definitivas y aún durante más de un siglo los conflictos entre la corona de Aragón y la de Castilla llevaron a cambios importantes en ellas.Por otro lado, la conquista feudal de Valencia implicó su reparto en señoríos y villas reales con la consiguiente necesidad de crear fronteras interiores para delimitarlos. Muchas veces estos límites se basaron en los existentes en época islámica, si bien fue usual que la sociedad feudal los interpretase según criterios propios y locales. Además, al estar ya en pleno siglo XIII, la organización de municipios se convirtió en la unidad básica de organización territorial, si bien existió una jerarquía entre las villas y los pueblos de su término.ABSTRACT: The origin of the borders of the medieval Christian kingdoms in Spain has much to do with the processes military and conquers over al-Andalus. This is the case of the kingdom of Valencia, created by King Jaime I in 1240 from several Muslim territories. Their outer borders were created from the boundaries between Christians and Muslims at that moment, but also by the political pacts with the crown of Castile distributing the territory of al-Andalus. But these borders were not definitive and still for more than a century the conflicts between Aragon and Castile took to important changes in them.On the other hand, the feudal conquest of Valencia implied its distribution between seigneuries and royal cities with the

    Full Text Available The operational numerical weather prediction model Lokalmodell LM with 7,km horizontal resolution was evaluated for forecasting meteorological conditions during observed urban air pollution episodes. The resolution was increased to experimental 2.8 km and 1.1 km resolution by one-way interactive nesting without introducing urbanisation of physiographic parameters or parameterisations. The episodes examined are two severe winter inversion-induced episodes in Helsinki in December 1995 and Oslo in January 2003, three suspended dust episodes in spring and autumn in Helsinki and Oslo, and a late-summer photochemical episode in the Valencia area. The evaluation was basically performed against observations and radiosoundings and focused on the LM skill at forecasting the key meteorological parameters characteristic for the specific episodes. These included temperature inversions, atmospheric stability and low wind speeds for the Scandinavian episodes and the development of mesoscale recirculations in the Valencia area. LM forecasts often improved due to higher model resolution especially in mountainous areas like Oslo and Valencia where features depending on topography like temperature, wind fields and mesoscale valley circulations were better described. At coastal stations especially in Helsinki, forecast gains were due to the improved physiographic parameters (land fraction, soil type, or roughness length. The Helsinki and Oslo winter inversions with extreme nocturnal inversion strengths of 18°C were not sufficiently predicted with all LM resolutions. In Helsinki, overprediction of surface temperatures and low-level wind speeds basically led to underpredicted inversion strength. In the Oslo episode, the situation was more complex involving erroneous temperature advection and mountain-induced effects for the higher resolutions. Possible explanations include the influence of the LM treatment of snow cover, sea ice and stability-dependence of transfer

Estudiar la variación estacional de la mortalidad por todas las causas según grupo de edad y sexo, en la ciudad de Valencia, España, durante el periodo 1976-1990, y su relación con la temperatura. Material y métodos. Se hizo un estudio ecológico de series mensuales de mortalidad global y temperatura media. La variable principal de resultado fue la mortalidad por todas las causas. Se calcularon las tasas de mortalidad específicas por grupos de edad (0-4, 35-39, 50-64, 65-74 y > o = 75 y sexo en la ciudad de Valencia, para cada mes, durante los 180 meses del periodo estudiado. Se obtuvieron las tasas promedio de mortalidad mensual y se calculó el porcentaje de variación. Asimismo, se utilizó el análisis gráfico para examinar la variación estacional de la mortalidad y para identificar la forma de la relación entre temperatura y mortalidad, ajustando la línea de regresión mediante el método Loess (suavizado móvil de regresión ponderado localmente. La asociación entre temperatura media y mortalidad se estimó mediante regresión lineal múltiple controlando por tendencia, estacionalidad y periodo. Resultados. Se observa un claro patrón estacional, con picos de mortalidad en los meses de invierno, y valores más bajos en los meses de verano y en los comienzos del otoño. El exceso de mortalidad para el mes de enero fue de 27.7% para el total de defunciones en mujeres, y de 19.5% en hombres; este exceso fue mayor en el grupo de 75 y más años. Gráficamente, la relación entre temperatura y mortalidad aparece en forma de V, con una menor mortalidad cuando la medida mensual de la temperatura media diaria es aproximadamente de 23 °C. Con base en esta relación, se construyeron dos variables complementarias, denominadas frío y calor. Estas variables explican un mayor porcentaje de la variabilidad de la mortalidad por todas las causas (47.6% en hombres y 54.8% en mujeres que el modelo con la temperatura como única

    Full Text Available Se evaluó el recuento de coliformes totales y Escherichia coli en canales bovinas sometidas a diferentes tratamientos que incluyeron combinaciones de los métodos de lavado, desinfección y vaporización, utilizando el diseño completamente aleatorizado de un factor con 3 repeticiones. El muestreo se realizó mediante frotis de superficie en tres áreas diferentes de la muestra (espalda, pecho y anca, que fueron posteriormente analizadas mediante el método de recuento en placa. Al aplicar secuencialmente los métodos de remoción microbiana se apreció la disminución progresiva en el recuento de coliformes totales y E. coli, y en la variabilidad de los datos, principalmente en los tratamientos C, D y E. La prueba de contrastes múltiples de Friedman mostró la inexistencia de diferencias estadísticas entre los recuentos de los tratamientos C y E en la muestra 2, indicando la ineficacia de la vaporización como coadyuvante de la acidificación para disminuir el recuento de los microorganismos de estudio. Las pruebas de comparación en muestras independientes mostraron resultados idénticos a la prueba de Friedman, excepto para el recuento de E. coli entre los tratamientos D y E, sugiriendo que la vaporización tiene efecto significativo para potenciar la disminución del recuento del microorganismo en las canales.

    Full Text Available Breeding programs in dairy goats are mainly based on milk production and composition. Murciano-Granadina goats are located principally in the central and southern regions of Spain. This study is focused in Valencia Community (Spain and the objective is to study the Murciano-Granadina livestock based on the database from Murciano-Granadina Goat Breeders Association of Valencia (AMURVAL.  The aim of this study is to analyze the relationship among different variables related with milk production; milk yield, fat, protein, lactose, SCC, the number of births, lactation number and season. This analysis is carried out by using the Self Organizing Map. This tool allows mapping high-dimensional input spaces into much lower-dimensional spaces, thus making much more straightforward to understand any representation of data. These representations enable to visually extract qualitative relationships among variables (Visual Data Mining. A total of 3221 Murciano-Granadina dairy goats from AMURVAL were chosen. Self Organizing Maps (SOM were used to analyze data with the system identification toolbox of MATLAB v7. Data were obtained from Official Milk Control during 2006 campaign. SOM considered in this study is formed by 21´14 neurons (294 neurons; the chosen architecture is given by the range of the input variables used. The map shown that more than 70% of the goats has milk yield greater than 300 kg per lactation and goat, indicating good performance of farms. Besides, the SOM obtained indicate a group of neurons that included goats with high SSC (2%. The use of Self Organizing Maps in the descriptive analysis of this kind of data sets has proven to be highly valuable in extracting qualitative conclusions and guiding in improving the performance of farms.

    Full Text Available We have studied the fossil Rhinocerotidae from Buñol (Valencia, Spain. It is realized as stratigraphic synthesis of the deposit and dated as Orleanium Mammal Age (lower-middle Aragonium, which is equivalent to the 4b Neogene MammaL Unit (zonation of Mein, 1976. We conclude that the fossil association is a thanatocoenosis, with strongly rounded elements. The paleoenvironment, in which this association was accumulated, was a marsh zone in the distal part of an alluvial fan. Two species of Rhinocerotidae have been determined, one of the ,genus Acerotherium and another of the genus Dicerorhinus. The second is more abundant than the former and probably it would be adapted to a marshy habitat. We describe and figure the more representative material of both species.

    The Solar Radiation Group of the University of Valencia, in collaboration with the National Institute of Meteorology (INM), recently began a database of erythemal UV irradiance measurements. Such measurements are obtained by a YES UVB-1 pyranometer (280-330 nm) that measures continuously, integrates the values and stores them in a database. The measured values are being compared with those obtained by the integration of the data registered by an Optronic OL 754 spectroradiometer (250-800 nm) considering clear days and different solar zenith angles. For the present study only the data corresponding to the summer (1999) are being considered because these are the days of the year with the higher erythemal values and also the season when people enjoy sunbathing. The results are used to deduce the ultraviolet index (UVI) related to the erythemal doses and the sunburn time. (author)

    Increased atmospheric radioactivity after the accident in Chernobyl was first detected on air filters. Measurements were begun in Valencia on May 2, 1986, with the maximum activity being observed around May 3-4, 1986. As a consequence of this accident, annual campaigns of measurements on migrating birds (several species of aquatic birds and song-thrushes) were started. The data corresponding to the campaign immediately after the accident (1986/87) show a generalized contamination (approximately 50% of the measured specimens). Significant levels of 134Cs, 137Cs and 110Agm were found. It is important to note that 110Agm is only present in Aythya ferina. In the successive campaigns in 1988/89 and 1989/91 few samples were found to be contaminated and only 137Cs was identified. Strontium-90 was measured and identified in some specimens, mainly in their bones.

    The SMOS space mission will soil moisture over the continents and ocean surface salinity with the sufficient resolution to be used in global climate change studies. With the aim of validating SMOS land data and products at the Valencia Anchor Station site (VAS) in a Mediterranean Ecosystem area of Spain, we have designed a sample methodology using a subdivision of the landscape in environmental units related to the spatial variability of soil moisture (Millán-Scheiding, 2006; Lopez-Baeza, et al. 2008). These physio-hydrological units are heterogeneously structured entities which present a certain degree of internal uniformity of hydrological parameters. The units are delimited by integrating areas with the same physio-morphology, soil type, vegetation, geology and topography (Flugel, et al 2003; Millán-Scheiding et al, 2007). Each of these units presented over the same pedological characteristics, vegetation cover, and landscape position should have a certain degree of internal uniformity in its hydrological parameters and therefore similar soil moisture (SM). The main assumption for each unit is that the dynamical variation of the hydrological parameters within one unit should be minimum compared to the dynamics of another unit. This methodology will hopefully provide an effective sampling design consisting of a reduced number of measuring points, sparsely distributed over the area, or alternatively, using SM validation networks where each sampling point is located where it is representative of the mean soil moisture of a complete unit area. The Experimental Plan for the SMOS Validation Rehearsal Campaign at the VAS area of April-May 2008 used this environmental subdivision in the selection and sampling of over 21.000 soil moisture points in a control area of 10 x 10 km2. The ground measurements were carried out during 4 nights corresponding to a drying out period of the soil. The sampling consisted of 700 plots with 4 volumetric SM cylinders and 7 Delta-T Theta

  2. La construcción de pianos en Valencia hasta inicios del siglo XX

    2007-12-01

    Full Text Available At around 1830 the use of pianos in Valencia becomes widespread. One of the most significant events that marked the progressive and increasing normalization of its use in the city was precisely the appearance of indigenous workshops dedicated to the piano-makings. Those first craftsmen who, in some cases –like for example, Pedro Gómez–, knew the ins and outs of the construction of the novel pianistic mechanics out of the country, opened their workshops in the decade of 1830 putting with it on record that already at that time started a local demand of instruments that justified sufficiently its work. It has been obtained information of four factories that worked between 1830 and the beginning of the 20th century. This said documentation states that the Valencian instruments made during that period (1830–1915 as much obtained great success in the internal market as in the outsider, and obtained prestigious awards in exhibitions and national and foreign displays. Also has provided with the knowledge of the production and marketing systems of those workshops, and of the characteristics that had the Valencian pianos made at the diverse times; that information has helped to value the economic and social function that had the Valencian manufacture of pianos in the 19th century and has allowed its comparison with the developed one in other Spanish provinces during the same time.

    Hacia 1830 comenzó a generalizarse el uso del piano en Valencia. Uno de los hechos más significativos que marcaron la progresiva y creciente normalización de su utilización en la ciudad fue precisamente la aparición de talleres autóctonos dedicados a la fabricación de pianos. Esos primeros artesanos que, en algunos casos –como por ejemplo, Pedro Gómez–, conocieron los entresijos de la construcción de la novedosa mecánica pianística fuera del país, abrieron sus talleres en la década de 1830 dejando constancia con ello de que ya se iniciaba por

    The soil vulnerability determines the sensitivity of the soil after an accidental radioactive contamination due to Cs-137 and Sr-90. The Departamento de Impacto Ambiental de la Energia of CIEMAT is carrying out an assessment of the radiological vulnerability of the different Spanish soils found on the Iberian Peninsula. This requires the knowledge of the soil properties for the various types of existing soils. In order to achieve this aim, a bibliographical compilation of soil profiles has been made to characterize the different soil types and create a database of their properties. Depending on the year of publication and the type of documentary source, the information compiled from the available bibliography very heterogeneous. Therefore, an important effort has been made to normalize and process the information prior to its incorporation to the database. This volume presents the criteria applied to normalize and process the data as well as the soil properties of the various soil types belonging to the Comunidades Autonomas de Valencia and Murcia.

    2009-01-01

    Bulk geochemical parameters and organic matter biomarkers in a short, high resolution gravity core (Lake Valencia, Venezuela) were examined to reconstruct anthropogenic impacts on the lake's conditions. During the period of ca. 1840-1990, sedimentary organic matter was characterized by high contents of total organic C (TOC) and total N (TN), low TOC/TN values as well as relatively enriched δ 13 C and δ 15 N signals, suggesting a primary autochthonous (algae and macrophytes) organic matter origin. The occurrence of large amounts of C 23 and C 25 relative to C 29 and C 31 n-alkanes indicated substantial inputs from submerged/floating macrophytes. The variations of C 32 15-keto-ol, tetrahymanol, diploptene, C 32 bishomohopanol, 2-methylhopane, dinosterol and isoarborinol concentrations over the investigated period record changes in the planktonic community structure, including Botryococcus braunii, bacteriavore ciliates, cyanobacteria, Eustigmatophytes and dinoflagellates. A principal shift occurred in the 1910s when cyanobacteria and dinoflagellates became more abundant at the expense and decline of B. braunii and Eustigmatophytes, likely related to increasing anthropogenic activity around the lake. A second shift (less obvious) occurred in the 1960s when cyanobacteria became the sole predominant planktonic class, coinciding with further deterioration of lake conditions

    The soil vulnerability determines the sensitivity of the soil after an accidental radioactive contamination due to Cs-137 and Sr-90. The Departamento de Impacto Ambiental de la Energia of CIEMAT is carrying out an assessment of the radiological vulnerability of the different Spanish soils found on the Iberian Peninsula. This requires the knowledge of the soil properties for the various types of existing soils. In order to achieve this aim, a bibliographical compilation of soil profiles has been made to characterize the different soil types and create a database of their properties. Depending on the year of publication and the type of documentary source, the information compiled from the available bibliography is very heterogeneous. Therefore, an important effort has been made to normalize and process the information prior to its incorporation to the database. This volume presents the criteria applied to normalize and process the data as well as the soil properties of the various soil types belonging to the Comunidades Autonomas de Valencia and Murcia.

    Full Text Available Chlamydia psittaci (Cp is an obligate intracellular bacterium, capable of invading birds and mammals. The prevalence of Cp in adult free-living birds is less than 5%, however in captivity the frequency is very variable (5 - 90%. Cp infections represent a health problem for birds living in captive centers, since in some cases it can be fatal thus generating more concern in threatened species. Therefore, the purpose of this study was the detection of Cp through the nested PCR in birds in captivity and its association to some specific taxonomic order. During 2015-2016, 44 cloacal swabs from six orders of birds were collected from the Valencia Aquarium (VA. The frequency of positives was as high as 77.3% and there was no association between the presence of Cp and a specific bird order. The results were associated with overcrowding conditions in which birds survive, absence of timely diagnosis of Cp in birds entering the VA and possible elevated levels of avian stress. It was confirmed that the state of captivity favors infection by Cp. These results demonstrate the need to promote the adaptation of conditions in captive bird habitats and the timely detection of Cp through molecular methods, mainly for spaces that act as centers for reception of specimens from confiscation, whose goal be their reintroduction to their natural habitat, as part of environmental conservation programs.

    Full Text Available Teucrium pumilum and T. libanitis have been cited from Valencia province (Spain since the middle of the XXth Century from the gypsic soils in the Valle de Ayora-Cofrentes shire. The analysis of specimens and labels is not conclusive; no specimen would certify the presence of any of these taxa. The field identification and their inclusion in a phyotosociological table (relevé by Rivas Goday are the only basis of their presence in the territory in a particular moment of the recent Spanish botanical history. Additionally, the unique herbarium specimen from Valencia, impossible to assign a concrete geographic locality, which was traditionally assigned to T. pumilum by some authors, is actually its congeneric T. carolipaui.Teucrium pumilum y T. libanitis son dos especies que han sido citadas como presentes en la provincia de Valencia desde mediados del siglo XX, para los yesos que afloran en la comarca del Valle de Ayora-Cofrentes. El análisis de las etiquetas de los pliegos de los herbarios no es concluyente; ningún pliego testigo certificaría la presencia de estas especies. La determinación de visu por parte de Rivas Goday, y su inclusión en una tabla de inventarios fitosociológica, son el único fundamento de su existencia en la zona en algún momento determinado de la reciente historia botánica española. Además, para T. pumilum, el pliego de herbario que tradicionalmente se ha asignado a la cita valenciana se trata de una confusión en la determinación por parte de algunos autores con su congénere T. carolipaui, siendo imposible al mismo tiempo asignar una localidad geográfica concreta a este material.

    2017-01-01

    Full Text Available Desde finales de los años 80 del pasado siglo, las ciudades europeas están desarrollando políticas de gestión urbana en la línea de lo que se ha venido en denominar city-marketing, urban-branding, o urbanismo neoliberal. El objetivo de estas políticas es posicionar a la ciudad en el contexto internacional potenciando su singularidad, para lo cual la principal estrategia ha sido la construcción de mega-edificios y la organización de eventos con impacto en los medios de comunicación globales. El aumento de la atractividad turística en las ciudades es utilizado como un indicador de éxito de dichas políticas. La ciudad de Valencia no ha sido ajena a este tipo de estrategias. El presente artículo realiza un análisis de las consecuencias que la política urbana neoliberal ha tenido en el turismo de la ciudad de Valencia, en especial en lo que se refiere a su imagen de marca y a la vinculación del mismo con la oferta cultural de la ciudad.

    Full Text Available Fundamentos. En el cribado de hipotiroidismo congénito en poblaciones con ingesta suficiente de yodo la proporción de neonatos con valores de TSH>5 mU/l debe ser inferior al 3%. El objetivo de este trabajo es conocer la prevalencia de déficit de yodo entre las madres y recién nacidos de Castellón y Valencia y, de manera secundaria, evaluar la influencia del día de obtención de la muestra y la utilización de antisépticos yodados. Métodos. Se estudió el valor de TSH en 91.853 recién nacidos entre 2004 y 2006 en Castellón y Valencia. Se compararon las medianas de los valores de TSH considerando las condiciones que define la OMS para analizar el indicador: toma de muestra tras 2 días de vida, y no utilización de antisépticos yodados. Se calcularon y compararon las proporciones de muestras con TSH>5mU/l. Resultados. Entre las muestras que cumplieron las condiciones para el análisis del indicador, la prevalencia de neonatos con TSH>5 mlU/ fue decreciente entre 2004 (2,2% IC95%:1,8%-2,6%, 2005 (2%; IC95%:1,6%-2,3% y 2006 (1,7%; IC95%: 1,4%-2%. La mediana de TSH en muestras de menos de 2 días fue significativamente superior (2,19 mlU/L; Q1-Q3: 1,35-3,40 frente a 1,36 mlU/L; Q1-Q3: 0,78-2,21 (p< 0,001. Considerando las muestras obtenidas tras 2 días de vida, el uso de antisépticos yodados determinó una mediana de TSH significativamente superior (1,54 miU/L; Q1-Q3: 0,88- 2,50 frente a 1,23 mlU/L; Q1-Q3: 0,72-1,97 (p< 0,001. Conclusiones. El valor del indicador de tirotropinemia neonatal en Castellón y Valencia es compatible con la definición de la OMS para poblaciones con una ingesta adecuada de yodo. El cribado neonatal de TSH es una buena herramienta para monitorizar la prevalencia de déficit de yodo, pero debe adecuarse el momento de la extracción y eliminarse la utilización perinatal de antisépticos yodados

    Full Text Available Las vacilaciones con las que se procedió a la realización de las reformas fiscales en el Reino de Valencia tras la abolición de los fueros en 1707 generaron numerosos conflictos que impulsaron a la Monarquía a reforzar la autoridad del intendente. Con tal finalidad, se potenció la tramitación por la vía reservada de las decisiones que adoptaba en materia hacendística. Pero el considerable incremento de su poder que ello comportó favoreció su utilización de forma abusiva en beneficio propio o de la red clientelar articulada a su alrededor. No obstante, las relaciones que mantenía el intendente con las élites locales contribuyen a explicar el eco desigual que alcanzaron las denuncias de corrupción que se formularon a lo largo de la centuria.AbstractThe hesitant application of the fiscal reforms implemented in the Kingdom of Valencia after the abolition of the regional laws in 1707 generated many conflicts that drove the Monarchy to reinforce the authority of the intendant. With this purpose, the Monarchy encouraged the reserved direct processing of the decisions adopted in financial matter. However, this caused a considerable increase of the intendant power that also implied the abusive usage for its own or the client network’s profit surrounding its figure. Nevertheless, the intendant relationships with the local elites explain the corruption accusations’ unequal eco throughout the century.

  20. Postmortem Inventories in Medieval Valencia. A Source for the Study of Household Consumption and Living Standards

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Basic questions about the nature of postmortem inventories in late medieval Valencia have rarely been asked. What distinguished them from other lists of goods and what was their legal basis? Why were inventories made? Which goods were listed and which ones omitted? How many inventories are preserved today? Which sectors of medieval society requested them? The answers that this paper provides clearly show the potential of a serial and quantitative usage of the Valencian inventory for the study of household consumption, an analysis that would enable us to measure far more accurately the changes in living standards in late medieval society to a degree that is difficult to achieve in other regions of Europe.

    Overweight and obesity are a public health problem worldwide affecting adults and children as well. The aim of this study was to assess overweight, lipid profile and cardiovascular risk ratios in 390 preschool children from low socio-economic level from Valencia, Venezuela. Nutritional anthropometric evaluation measured by body dimensions, and serum determination of cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol and cardiovascular risk factors, were determined. 95% of the children were in relative and critical poverty. 14.3% of undernutrition and 20.8% of overweight was found. Lipid profile was in normal range, with no significant differences by sex, but higher values for HDL-cholesterol and risk ratios were found in children aged 1 to 3.99 years. Even though no differences were found by nutritional status, overweight children had higher values for lipids, except HDL-cholesterol. 6.3% of overweight children had cholesterol > or =170 mg/dL, 16.5% LDL-cholesterol > or =110 mg/dL, 40.5% triglycerides > or =75mg/dL and 100% HDL-cholesterol <45 mg/dL. Overweight and lipid profile alterations were present in an important group of the children, which increase their risk of obesity and chronic non-transmissible diseases. Nutritional and educational intervention should be addressed.

    Orange jasmine, Murraya paniculata and curry leaf tree, Bergera koenegii are alternative hosts for Diaphorina citri, the vector of Candidatus Liberibacter asiaticus (CLas), the pathogen of huanglongbing (HLB) in citrus. D. citri feeds on the phloem sap where CLas grows. It has been shown that orange jasmine was a better host than curry leaf tree to D. citri. In addition, CLas can infect orange jasmine but not curry leaf tree. Here, we compared the phloem sap composition of these 2 plants to the main host, Valencia sweet orange, Citrus sinensis. Phloem sap was analyzed by gas chromatography-mass spectrometry after trimethylsilyl derivatization. Orange jasmine was the highest in proteinogenic, non-proteinogenic amino acids, organic acids, as well as total metabolites. Valencia was the highest in mono- and disaccharides, and sugar alcohols. Curry leaf tree was the lowest in most of the metabolites as well as total metabolites. Interestingly, malic acid was high in Valencia and orange jasmine but was not detected in the curry leaf. On the other hand, tartaric acid which can prevent the formation of malic acid in Krebs cycle was high in curry leaf. The nutrient inadequacy of the phloem sap in curry leaf tree, especially the amino acids could be the reason behind the longer life cycle and the low survival of D. citri and the limitation of CLas growth on this host. Information obtained from this study may help in cultivation of CLas and development of artificial diet for rearing of D. citri.

    Full Text Available Abstract Background In most countries the coverage of seasonal influenza vaccination in pregnant women is low. We investigated the acceptance, reasons for rejection and professional involvement related to vaccine information in pregnant women in Valencia, Spain. Methods Observational retrospective study in 200 pregnant women, 100 vaccinated and 100 unvaccinated, were interviewed during the 2014/2015 vaccination campaign. Electronic medical records, immunization registry and telephone interviews were used to determine reasons for vaccination and immunization rejection. Results 40.5% of pregnant women in the health department were vaccinated. The midwife was identified as source of information for 89% of women. The vaccine was rejected due to low perceptions of risk of influenza infection (23%, lack of information (19%, considering the vaccine as superfluous (16%, close proximity of delivery date (13% and fear of side effects (12%. Conclusion Pregnant women in Spain declined to be vaccinated due to under-estimation of the risk of contracting or being harmed by influenza, and lack of information. Interventions aiming to optimize vaccination coverage should include information addressing the safety and effectiveness of the current vaccine together with improved professional training and motivation.

    Bottom sediment samples from 121 sites of the Lake Albufera of Valencia were analyzed. Dieldrin, endrin, heptachlor and op'-DDT were not detected (<0.01 ng g(-1)) in 88-93% of the sites. Aldrin and HCB concentration ranges were between <0.01 and 0.1 ng g(-1) in 86% and 94% of the sites, respectively. Heptachlor-epoxide and lindane 95% confidence intervals were 0.2-0.5 and 0.06-0.12, respectively. The greatest average concentration corresponds to pp'-DDE, pp'-DDD and pp'-DDT. The sum of six isomers and derivatives of the DDT average concentration reaches 2.1 ng g(-1), as opposed to 2.7 ng g(-1) for the sum of 13 pesticides considered. In the site with a major contamination, 27.0 ng g(-1) of pp'-DDD and 12.8 ng g(-1) of pp'-DDT were accumulated. The DDE:DDT proportion average was 0.37, indicating an aged DDT contamination. Concentrations of pesticides in sediments were compared to three sediment quality guidelines, and indicated that a low biological effects level can be expected in either sediments or aquatic organisms.

    Recent years have seen increasing public interest in issues related to energy saving and concern for the environment. It is important to highlight the work of public institutions in this respect. This was the motive that led the University of Valencia to finance a pilot project with the objective of studying useful initiatives for optimising energy consumption in accordance with the institution's needs as well as the incorporation of innovative and more efficient technologies. The approach was to consider various aspects ranging from the analysis of the current energy consumption and the state of the installations, through the substitution of some energy inefficient components, to the study of the possible installation of a photovoltaic solar powered electricity generation station connected to the network. Also purely technical questions on economic efficiency should not be forgotten as this could lead to a reduction in energy consumption and the optimisation of the current energy consuming equipment, since generally, it is this question that limits the possible energy saving actions.

    In Spain syphilis shows an increasing trend from last decade and multiple papers reported an increasing of exposed population. Our aim was to describe the evolution of the incident of the syphilis in the geographical frame of the city of Valencia, to identify the characteristics and practices of risk of the affected ones. A classic design of vigilance of public health was applied, longitudinal retrospective study. Geographical area: the city of Valencia. January 2003-December 2014. age and sex, national origin, dates of access to the sanitary system, date of diagnosis, clinical forms of presentation, conducts of risk, and practices of risk. The annual impact of the disease evolved from 2.4 × 10(5) in 2004 up to 14.5 × 10(5) in 2014. Males (82.96%) masculinity rate: 4.8. Major specific incidence took places on age-groups 35-39 years with 16.49 × 10(5) and 40-44 years with 16.98 × 10(5). The difference between women stands out according to origin: middle ages in autochthonous (39.72 years) opposite to foreigners (32.91 years); P = .004. The primary forms were 5 times more probable in males. The major factor of risk was to have multiple couples (54.89%), man-to-man homo or bisexuals reaches 90.0% of it. The HIV (human immunodeficiency virus) infection was 29.07% in males and 4.35% in women. Precedent of multiple couple relations would not be a minor of 42 times more likely among the homosexual population with syphilis. Major determinant of risk were the relations with multiple pairs and the prevention will have to be focused to the group of men who practice sex with men. Copyright © 2016 Elsevier España, S.L.U.

    Full Text Available The Musical Societies are the cultural agent that produces most musical events in Valencia, gathering around them the vast majorities of local amateur musicians, who are the main support that conforms them and at the same time leads its management. Its rise and proliferation has led to the growth and complexity of their structures, making it increasingly difficult operation with management based on volunteerism. In this study we analyzed each of the areas of Music Societies from the perspective of its managers in charge, aware of its management, and its musicians, who are aware of the real effects of it. Thus checking to what extent each structural framework needs an increasingly dedicated and expert figure, we also show to the Musical Societies some operating possibilities at their fingertips and finally we enable a self-analysis that objectively will assess the advantages of professionalism in management.

    The construction of the House of the Dockyards in the coast line of the city by the local government was the result of the urban development policy of Valencia, showing that the city itself was centred in showing an image of propriety and beauty in every place, and also the influence of Martin I and his unsatisfied wishes of constructing a palace near the coast of Barcelona. Despite the fact that the original purpose of the building was to be used a warehouse of the port, the needs of the local government forced it to extend its functions turning it into a palace receiving prominent figures and being the emplacement of many ceremonies and banquets. The importance of the House of the Dockyards can be appreciated in its dimensions, as we can see in the engravings and landscapes illustrations of El Grao, and in the work produced by Joan del Poyo after returning from Barcelona, where he served the king Martin I, probably in the Royal Palace of the city.



    La construcción de la Casa de las Atarazanas en la línea litoral de la urbe por parte del gobierno municipal se debió tanto a la política urbanística emprendida por el patriciado urbano centrada en mostrar una imagen de belleza y decoro en todos sus frentes, como a la influencia que pudo haber ejercido Martín I en el reino de Valencia, y su deseo no satisfecho de edificar en Barcelona un palacio cercano a la costa. Aunque en un primer momento la finalidad del edificio fue la de servir de almacén de los productos del puerto, las necesidades de gobierno hizo ampliar sus funciones, asemejándose más a la de una casa o palacio, que acogería a personajes ilustres en su llegada marítima y sería el emplazamiento de ceremonias y ágapes. La importancia de la Casa de las Atarazanas se aprecia tanto en sus grandes dimensiones, como constatan los grabados e ilustraciones paisajísticas del

    To describe the drivers associated with HPV vaccination in adolescent girls and their parent's opinion on the vaccine. We conducted an observational and cross-sectional study on adolescent girls and their parents in Valencia (Spain), between September 2011 and June 2012. A consultation was made at a random sample of schools of the 14-year-old girls that should have received the vaccine in the free vaccination programme. We ran a personal survey on knowledge and attitudes regarding HPV infection and the vaccine. A binary logistic regression model was performed to determine which factors were most associated with vaccination. The survey was run on a binomial of 1,278 girls/mothers in 31 schools, to which 833 girls and their mothers responded (64.0%). The factors associated with vaccination were: country of origin of the families (adjusted OR [aOR]: 0.49; 95% confidence interval [95%CI]: 0.24-0.98), civil status of the parents (aOR: 0.33; 95%CI: 0.13-0.81), knowledge/beliefs about the vaccine when the source of information was the nurse (aOR: 1.83; 95%CI: 1.01-3.35), information source about the vaccine (aOR: 2.32; 95%CI: 1.37-3.92), preventive health centre visits (aOR: 2.1; 95%CI: 1.10-4.07), and nurse advice (aOR: 6.6; 95%CI: 3.19-13.56). The main factor associated with HPV vaccination was the advice of health professionals. Therefore, the most effective interventions to improve vaccination coverage should focus on health professionals. Copyright © 2017 SESPAS. Publicado por Elsevier España, S.L.U. All rights reserved.

It is right that the main instruments that the king had to apply his aggressive policy was, on the one hand, the centralized and complex organization around the General Treasure of the Crown of Aragon and, later on, to the Treasure of the Kingdom of Naples; on the other hand, to the solid banking infrastructure built around the Mediterranean. Therefore, both of them were based on the confidence and guaranties offered by the powerful ordinary and non ordinary tax structures of the kingdom, and the solid financial support given by the institutions of the kingdom.

    Due to their low solubility in water, oil-based bioactive compounds require dispersion in a surface-active agent or appropriate solvents to ensure maximum contact with microorganisms. These combinations, however, may change their physical and/or chemical characteristics and consequently alter the desired functionality. The objective of this study was to determine the impact of selected dispersing agents, ethanol, dimethyl sulfoxide (DMSO), and Tween-80, on cold-pressed terpeneless (CPT) Valencia orange oil to function as a free radical scavenger and an antimicrobial food additive. When dissolved in ethanol or DMSO, the orange oil fraction had similar minimum inhibitory concentrations (MIC) for Listeria monocytogenes ATCC 19 115 (0.3% and 0.25% v/v respectively), which were significantly lower (P orange oil (up to 3%) in an aqueous solution of 0.1% Tween-80 yielded no inhibitory activities against any of the test bacteria. However, the 1% natural orange oil dispersed in Tween-80 exhibited 56.86% 2,2-diphenyl-1-picryl hydrazyl (DPPH) radical inhibition versus 18.37% and 16.60% when the same level of orange oil was dissolved in DMSO or ethanol, respectively. At the same orange oil concentration, the oil/Tween-80 suspension yielded 57.92% neutralization of hydroxyl radicals. This represents 71.37% of the mannitol antioxidant activity, which was used as a positive control. These findings suggest that Tween-80 is an appropriate dispersing agent only if the antioxidant functionality is desired. If both antimicrobial and antioxidant properties are needed, the CPT Valencia orange oil should be dispersed in either DMSO or ethanol. (c) 2010 Society of Chemical Industry.

As a result, nine rootstocks commonly used in tropical zones: 'C-35', 'Carrizo', 'Swingle' citrumelo or CPB 4475, 'Cleopatra', 'Sunki × English', 'Volkamer', 'Webberi' and 'Yuma' were evaluated. The plants were established in 2001 and were evaluated for vegetative growth, fruit yield and quality for 10 years (2004-2013. The obtained results indicated that 'Sunki × English' and 'Volkamer' were the best rootstocks for fruit yield and the worst was 'Yuma'. Furthermore, all of the rootstocks, except 'Yuma', stabilized their height in the last year. In terms of volume, 'Amblycarpa' and 'Cleopatra' were the bigger plants and 'Yuma' was the smallest. In addition, for yield efficiency, 'Yuma' had the best rootstocks, followed by 'Sunki × English'. All of the rootstocks showed a similar fruit quality, except for 'Sunki × English', which obtained the highest total soluble solids/total titratable acids ratio.

    Full Text Available This work aims to improve the knowledge of the flood that took place in Valencia, Spain, in 1957. In other words, the aim is to test if it is possible to explain the flood waves with the incorporation of sediment cycle to a distributed hydrological model. Furthermore, this work aims to be aware of the current consequences of a similar event, taking into account land use changes, particularly, the urban rise in the lower basin, and the current flood defenses of the city. To do this, the hydrological model was implemented in the current basin situation. Once implemented, a reconstruction of precipitation at hourly discretization for the 1957 event was made and the sedimentological sub-model was calibrated. Then, the hydrographs in the chosen points were obtained. Finally, a simulation using the 1957 precipitation in the current basin situation was made, in order to be aware of the current consequences.

    Ecoepidemiological studies of cutaneous leishmaniasis and regular monitoring of Lutzomyia species have generated a knowledge base that can be used for control and prevention strategies targeted at the disease transmission dynamics in focal areas of Colombia. In this study, the presence and spatial distribution of phlebotomines of medical importance in the municipalities of Tierralta (El Loro and Tuis Tuis villages) and Valencia (Guadua and Mieles villages) were determined. Entomological surveys were performed in 2015 (months of June, September and November) and samples were collected via CDC-traps located in intradomicilary and peridomiciliary areas in the municipalities of Tierralta and Valencia (Department of Córdoba, Colombia). Active searches were also carried out with a mouth aspirator to collect adult phlebotomines from resting sites. ANOVA and Kruskal-Wallis tests were performed to assess if the differences between the communities of phlebotomines. Spatial distribution maps of the Lutzomyia species were generated. A high species diversity of Lutzomyia was observed with a total of 1677 Lutzomyia individuals belonging to 12 species. Among these species, Lu. panamensis was the most abundant (80.18%). The composition of the intradomicilary and peridomiciliary phlebotomines varied significantly (F = 0.9962; df = 1; p = 0.02895). Species like Lu. carpenteri, Lu. camposi, Lu. dysponeta, Lu. atroclavata and Lu. yuilli yuilli were recorded for the first time in the Department of Córdoba, Colombia. The spatial distribution shows that Lu. panamensis and Lu. gomezi are predominant and present in areas with high concentration of houses. This study provides basic information on new records of phlebotomines in the Department of Córdoba. The results suggest that greater vector-human contact occurs in the peridomiciliary environment and that a high number of Lutzomyia species associated with the transmission of leishmaniasis are present in Colombia.

    Since 2001, the Valencia Anchor Station is currently being prepared for the validation of SMOS land products. The site has recently been selected by the Mission as a core validation site, mainly due to the reasonable homogeneous characteristics of the area which make it appropriate to undertake the validation of SMOS Level 2 land products during the Mission Commissioning Phase, before attempting more complex areas. Close to SMOS launch, ESA defined and designed the SMOS Validation Rehearsal Campaign Plan with the purpose of repeating the Commissioning Phase execution with all centers, all tools, all participants, all structures, all data available, assuming that all tools and structures are ready and trying to produce as close as possible the post-launch conditions. The aim was to test the readiness, the ensemble coordination and the speed of operations to be able to avoid as far as possible any unexpected deficiencies of the plan and procedure during the real Commissioning Phase campaigns. For the rehearsal activity which successfully took place in April 2008, a control area of 10 x 10 km2 was chosen at the Valencia Anchor Station study area where a network of ground soil moisture measuring stations is being set up based on the definition of homogeneous physio-hydrological units, attending to climatic, soil type, lithology, geology, elevation, slope and vegetation cover conditions. These stations are linked via a wireless communication system to a master post accessible via internet. Complementary to the ground measurements, flight operations were performed over the control area using the Helsinki University of Technology TKK Short Skyvan research aircraft. The payload for the campaign consisted of the following instruments: (i) L-band radiometer EMIRAD (Technical University of Denmark, TUD), (ii) HUT-2D L-band imaging interferometric radiometer (TKK), (iii) PARIS GPS reflectrometry system (Institute for Space Studies of Catalonia, IEEC), (iv) IR sensor (Finnish

    Wastewater can provide a wealth of epidemiologic data on common drugs consumed and on health and nutritional problems based on the biomarkers excreted into community sewage systems. One of the biggest uncertainties of these studies is the estimation of the number of inhabitants served by the treatment plants. Twelve human urine biomarkers -5-hydroxyindoleacetic acid (5-HIAA), acesulfame, atenolol, caffeine, carbamazepine, codeine, cotinine, creatinine, hydrochlorothiazide (HCTZ), naproxen, salicylic acid (SA) and hydroxycotinine (OHCOT)- were determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS) to estimate population size. The results reveal that populations calculated from cotinine, 5-HIAA and caffeine are commonly in agreement with those calculated by the hydrochemical parameters. Creatinine is too unstable to be applicable. HCTZ, naproxen, codeine, OHCOT and carbamazepine, under or overestimate the population compared to the hydrochemical population estimates but showed constant results through the weekdays. The consumption of cannabis, cocaine, heroin and bufotenine in Valencia was estimated for a week using different population calculations. Copyright © 2016 Elsevier B.V. All rights reserved.

    Are the policies designed by decision-makers differing from society's wishes and preferences. The present paper analyzes the divergences between forest policy and public opinion in the Region of Valencia (Comunidad Valenciana) in Eastern Spain. The data is based on an extensive telephone survey of the general public on their perception of forestry issues. The issues studied include attitudes regarding forest fires, silvicultural treatments, the externalise produced by forest owners, and the state forest services role related to these issues. In total, the answers of 823 respondents were analyzed using classification trees. The results of the analysis showed a large divergence between the desires, preferences and priorities of society, on the one hand, and the policies implemented by the regional government, on the other. The study concludes that communication strategies concerning sustainable forest management need to be further developed by the responsible authorities, with the input of the research community.

    Full Text Available El uso de la terapia de vacío en el tratamiento de heridas complejas y de evolución tórpida tiene sus inicios en los años cuarenta. Sin embargo, la experiencia con su utilización en la población infantil es mucho más reciente. En la actualidad no disponemos de estudios científicos contrastados y con nivel de evidencia A para emitir conclusiones firmes en estos casos; a pesar de ello, la experiencia clínica acumulada hasta el momento es satisfactoria en la mayoría de los casos. En la gestión sanitaria moderna, el control de recursos y costes es hoy en día un pilar fundamental; es por ello que contar con una terapia de estas características constituye un recurso de gran valor, sobre todo cuando la intención es minimizar la estancia hospitalaria y a la vez mejorar la calidad de vida del paciente, lo cual es especialmente importante cuando se trata de niños. Presentamos la experiencia en el uso de terapia de vacío en pacientes pediátricos del Servicio de Cirugía Plástica y Reconstructiva del Hospital La Fe de Valencia, España, entre los años 2007 y 2010.Vacuum assisted therapy in complex and complicated wounds has been used since the 40s; however, it has only been applied in paediatric patients recently.

    Due to the social, economical and environmental importance of agro-ecological wetlands, strategies for periodical evaluation of their environmental quality should be developed, particularly in those areas were a mixture of land uses are supporting the survival of wildlife and migrant species as is the case of most Mediterranean coastal wetlands. The aim of this work is to develop a strategy for a long-term assessment of the environmental quality of soils in a rice-wetland: L'Albufera Natural Park, Spain, in the surroundings of the metropolitan area of Valencia. The area was officially declared as Natural Park in 1986, integrating both the traditional irrigation system and the ecological importance derived from being a Mediterranean Wetland that is now transformed to a large extent in a rice-wetland allowing the presence of a large variety of migrant spices. The methodology consisted in the monitoring of 20 sites distributed in 5 sectors in and around the natural park of potentially contrasting anthropogenic pressure and land use. Soil samples collection were instrumented in two campaigns. The first one was in 1989 (three years after the official declaration as Natural Park of the wetland), and the second 19 years later in 2008. Seven heavy metals (Cd, Co, Cr, Cu, Ni, Pb and Zn) were analyzed to determine its total and extractable fractions by treatment with EDTA. Atomic Absorption Spectrometry, using graphite furnace when necessary, was used for the determination of metals. To evaluate the quality of soils at each sampling date four indicators were obtained, namely, Contamination Factor (CF), Geoaccumulation Index (Igeo), Pollution Load Index (PLI) and Potential Ecological Risk Index (PERI). Results obtained with quality indicators were further compared to obtain temporal and spatial trends using Geographical Information systems procedures. In general, there is a reduction of metal contents in the study area in both dates. The trend of metals according to average

    The study was carried out to estimate the dietary intake of polybrominated diphenyl ethers (PBDEs) in the Region of Valencia (Spain) in order to evaluate the resultant risk. The PBDE levels in fish and seafood (a total of 206 samples) were determined. Dietary intake was estimated using results of PBDE analyses in fish and seafood marketed in the Region of Valencia over the period 2007-2012 and data of the first Valencian Food Consumption Survey, conducted in 2010. Two scenarios were assumed for left-censored results: the lower-bound (LB) scenario, in which unquantified results (below the limit of quantification (LOQ)) were set to zero and the upper-bound (UB) scenario, in which unquantified results were set to the LOQ and two approaches (deterministic and probabilistic) were compared. The mean PBDE concentration in fish and seafood from Valencian markets was between 0.97 and 3.87 ngg(-1) w.w. and was similar to that reported recently by European Food Safety Authority (EFSA). Among the analysed congeners, BDE-47 showed the highest levels and salmon, mackerel and swordfish were the most contaminated species. The average estimated daily intake of the sum of PBDEs (upper bound scenario; probabilistic approach) for adults and children were 0.137 ngkg(-1) body weight (b.w.) day and 0.180 ngkgb.w.(-1)d(-1), respectively. In relation to risk analysis, calculated margins of exposure (MOEs) for the BDE-47, -99 and -153 congeners for children and do not indicate a health concern with respect to current dietary exposure in the Valencian Region and only 0.05% of the adult population and a 0.1% of children could be in risk derived by BDE-99 intake through fish.

    Full Text Available En los últimos años, el uso de vidrio laminado como elemento estructural se ha incrementado considerablemente en construcciones arquitectónicas, sobre todo en fachadas, cubiertas, escaleras o ventanas de seguridad. El cálculo de estos elementos tipo sándwich no es sencillo debido a la combinación de las propiedades mecánicas del vidrio (elástico-lineales con las del polímero interior (viscoelástico-lineales. Recientemente, algunos autores han propuesto el concepto de espesor efectivo para el cálculo simplificado de elementos de vidrio laminado bajo carga estática, utilizando un modelo monolítico con una rigidez equivalente igual a la del elemento laminado. Debido a la variación de propiedades del laminado con la temperatura, introducidas por el polímero viscoelástico, para cada cambio de temperatura se tiene un espesor efectivo diferente, lo que conlleva un mayor número de evaluaciones para cada una de las situaciones de trabajo del elemento laminado. En este trabajo se propone el concepto de módulo de elasticidad efectivo como una alternativa más eficiente para el cálculo con modelos de elementos finitos. La metodología propuesta se valida mediante ensayos experimentales realizados en placas de vidrio laminado sometidas a una carga uniformemente distribuida.

    In October 2008, Valencian Community started its human papillomavirus (HPV) vaccination schedules for 14 year-old girls. The aim of this study is to assess knowledge about HPV infection and its vaccine among the mothers of these girls, and to identify factors associated with the willingness to vaccinate their daughters. Cross-sectional study by means of a questionnaire to mothers of girls born in 1995, and attending secondary schools in the province of Valencia during 2010-2011. Cluster stratified random sample (n=1279). percentages, confidence intervals, OR, Chi-squared and multivariate logistic regression contrasts. A total of 833 (65.1%) questionnaires were completed. The results obtained showed that, 76.6% of mothers had vaccinated their daughters against HPV; 93.8% knew about the vaccine, particularly through television (71.5%); and 78.5% received positive advice from a health professional which increased the vaccination of their daughters (OR: 2.4). There was low overall knowledge about HPV infection and vaccination. Confidence of the mothers in vaccines as a preventative method increases the HPV vaccination (OR: 3.8). The first reason for refusal was the fear of adverse events (45.6%). Apparently, the media does not influence the willingness to vaccinate. It would be desirable to minimize the perception of risk of the vaccine. Positive health advice from a health professional can have a positive effect on vaccination. There is a gap between the level of knowledge and decision-making to vaccinate. Copyright © 2014 Asociación Española de Pediatría. Published by Elsevier España, S.L.U. All rights reserved.

    Cold pressed orange oils contain predominantly d-limonene (approximately 95%) and various other lower concentration monoterpenes, sesquiterpenes, sinensals plus 3 key aliphatic aldehydes: hexanal, octanal. and decanal. The aldol self-condensation products or "dimers" for each aldehyde have been postulated as being present at low concentrations in the oil. However, to date only the hexanal dimer has been previously reported. In this paper, cold pressed Valencia orange oil was fractionally distilled/folded and analyzed by GC and high resolution GC-MS to detect these compounds on 2 different capillary column phases. Subsequently the hexanal, octanal, and decanal self-aldol condensation products, 2-butyl-2-octenal, 2-hexyl-2-decenal, and 2-octyl-2-dodecenal, respectively, were detected in the folded oil. These predominantly trans configuration isomeric compounds were synthesized, to confirm them as being present in nature and evaluated organoleptically by a panel of evaluators. To further confirm the mechanism of their formation, the enriched oil was made into a simple beverage to show the effect on the formation of these aldol compounds under acidic conditions. Finally aliphatic aldehydes from hexanal to undecanal were reacted together in various combinatorial pairs to give an additional 33 self and mixed aldol condensation products, some of which were also detected in the folded oil. This paper discloses the structural elucidation and synthesis of 8 novel aldol condensation products found at trace concentrations in citrus and leading to a further 31 mass spectrally determined aldol products. Sensory evaluations and application of some of these components were demonstrated in a model citrus beverage. © 2017 Institute of Food Technologists®.

    Full Text Available Las normativas legales sobre residuos de plaguicidas son cada vez más exigentes. Con frecuencia, hay una reducción significativa en el Límite Máximo de Residuos (LMR y en casos severos una prohibición de su uso. La estrategia de control fitosanitario debe tener en cuenta los niveles de residuos que quedan en la fruta y la cinética de disipación que disminuye los riesgos toxicológicos y comerciales. El clorpirifós es un insecticida utilizado en cítricos para el control de diversas plagas. La legislación argentina establece un LMR de 0,3 mg/kg para fruta entera y un Período de Carencia (PC de 21 días. Este valor coincide con el exigido por la Unión Europea (UE, excepto en mandarinas, y por la Federación de Rusia. En el presente trabajo se estudió la cinética de degradación y persistencia del clorpirifós en dos variedades de naranjas y tres de mandarinas.Los ensayos se realizaron con clorpirifós 48% (concentrado emulsionable en la preparación de un caldo con 120 cm3 cada 100 L de agua. Se utilizó una pulverizadora de turbina y un volumen de 2000-2500 l/ha. La degradación de residuos en frutas se estudió durante 120 días con toma de muestras periódicas. Los datos experimentales se utilizaron para establecer un modelo matemático de degradación en función del tiempo. En todos los casos, los residuos iniciales superaron el LMR y la disipación siguió un modelo logarítmico. Hasta el PC la eliminación fue rápida, con una reducción del 69 al 82% de los residuos. Luego continuó una fase de eliminación más lenta con niveles al final del ensayo entre 0,03 mg/kg y 0,01 mg/kg. En el PC se cumple con el LMR fijado por la legislación nacional y de los países compradores. La aparición de residuos en el final delensayo indica una gran persistencia del clorpirifós.

    Rice paddy fields are large sources of anthropogenic methane (CH4) and therefore many studies have assessed CH4 fluxes from rice paddy fields, mainly in Asia where most of the rice cultivation takes place. However, rice is also cultivated in the Mediterranean, where climatic and management conditions greatly differ. In the Albufera of Valencia, the largest freshwater lagoon in Spain, rice paddy fields have the particularity of being flooded not only while the rice grows, but also after the harvest during the winter. These flooding conditions might result in emissions which are very specific of this ecosystem, and cannot be extrapolated from other studies. We studied CH4 fluxes in a rice paddy field in the Albufera of Valencia at different stages of rice cultivation using the eddy covariance technique and static chambers. We additionally measured carbon dioxide (CO2), water fluxes and nitrous oxide (N2O) fluxes with eddy covariance and chamber methods respectively, in order to obtain a full greenhouse gas (GHG) budget. Our study also aimed at providing a mechanistic understanding of GHG emissions at different stages of rice cultivation, and therefore we also used the Enhanced and Normalized Vegetation Indexes (EVI and NDVI, respectively), derived from remote sensing images. The general ecosystem functioning encompasses three different phases. The first one, over the autumn and the winter, a biological dormancy period causes low CO2 emissions (ca. 1-5 µmol m-2 s-1), which coincides with the EVI and NDVI. The intermittent flooding taking place during this period is expected to cause CH4 emissions. Then, during the spring months (March-May), larger CO2 respiratory emissions take place during the daytime (> 5 µmol m-2 s-1) due to an increase in air temperature, which turn to neutral at the end of spring due to the start of photosynthesis by the rice. The third phase corresponds to the vegetation growth, when the net CO2 uptake increases gradually up to maximum CO2

    Full Text Available Even though with the great relevance of the ports for economical and social development of the countries, there is an issue that deserves attention of the managers and society. It is the fact that the port activities cause environmental impacts such as siltation in aquatic environs, changes in the fauna and flora, atmosphere emissions, solid waste generations and among others. In this context, the environmental information management is important as for the port managers as for society since it allows to know the impact level generated and the commitment level with the sustainability over the time. One of the ways to measure information is to verify the manager commitment levels with the environmental management. As a consequence of this understanding the present research aims to identify the environmental sustainability in Port Authority of Valencia (APV. As methodology, it is used an applied questionnaire to the top management of APV and it is held a content analyses of the Sustainability Report of APV to understand the commitment level with environmental aspects. The questionnaire application results show a great APV commitment with environmental aspects (Materials, Energy, Water, Biodiversity, Emissions, Wastewaters, Wastes, Administrative and judicial sanctions, Product and Service Impacts, Transport Impacts, Fines, Non-monetary Sanctions, Non-conformities, however, the Sustainability Report analyses shows that not all items are shown (80% is shown. It is also verified that the APV commitment is not limited to the speech or port environmental policy, but also to the items that show and evaluate the environmental aspect performances.

    Dietary exposure of the Valencia Region population to polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and PCBs was assessed in the Region of Valencia in 2010-2011. A total of 7700 food samples were collected. Occurrence data were combined with consumption data to estimate dietary exposure in adults (>15 years of age) and young people (6-15 years of age). The estimated intake was calculated by a probabilistic approach. Average intake levels (upper-bound scenario) were 1.58 and 2.76 pg toxic equivalent (TEQ) kg -1 body weight (bw) day -1 for adults and young people, respectively. These average intakes are within range of the tolerable daily intake of 1-4 pg WHO-TEQ kg -1 bw day -1 recommended by WHO, and slightly above the tolerable weekly intake (TWI) of 14 pg TEQ kg -1 bw week -1 and the Provisional tolerable monthly intake of 70 pg TEQ kg -1 bw month -1 set by the Scientific Committee on Food and the Joint FAO/WHO Expert Committee on Food, respectively. These results show that the contamination levels in food and therefore the exposure of the general population to PCDD/Fs and PCBs have declined in this region and therefore show the efficiency of the European risk-management measures. In terms of risk characterisation, the results showed that, under the upper-bound scenario, 22% of the adult and 58% of the young people population could exceed the TWI.

    Full Text Available The practice of entail, a key source of stability for the patrimony of thenobility over the centuries, nonetheless created its own contradictions. Several of thesearose, in the case of Valencia, from the normative changes that followed the decrees ofthe Nueva Planta, due to the differences between Castilian law and the abolished Valencian fueros. But many other contradictions resulted from the inconsistent regulation ofentail under the fueros; from debates over the law; from the sometimes confused stipulations of the founders; and even from uncertainty over the purpose of the entailedproperties. This article, drawing on disputes over entailed estates brought before theAudiencia of Valencia, will analyze problems including ambiguity in terminology; the contention between primogeniture and appeals for plural inheritance; the difficultyin defining the established order of succession; the incompatibility question; the extinction of inheritance for lack of descendants; the acceptance of illegitimate children and clerics;previously arranged disinheritance; the extension of the encumbrance in perpetuity; therecognition of real rights against entailed properties; and the alienation of parts of entailedestates under certain circumstances.Cimiento fundamental de la estabilidad patrimonial de la nobleza a través de los siglos, el mayorazgo generaba, no obstante, sus propias contradicciones. Algunas de ellas traían origen, en el caso valenciano, de los cambios normativos que siguieron a los decretos de Nueva Planta, al diferir en la determinación de ciertos aspectos las leyesde Castilla de los fueros abolidos. Pero otras muchas se derivaban de la escasa regulación foral en la materia, de las dudas de la doctrina, de las disposiciones, en ocasiones confusas, de los fundadores, e incluso de los mismos fines a que servía la propiedad vinculada.

    Full Text Available The Apostle door of the Cathedral of Valencia, Built in the first Half of the 14th c, is one of most extraordinary examples of the monumental main fronts of southern Gothic. The intervention carried out was fruit of an agreement of sponsorship among companies and institutions and was aimed at realizing conservation work on the masonry, degraded by poor building functioning, and the sculptures, replacing by replicas those of apostles removed thirty years ago. Various construction operations, such as emptying the terrace of the false triforium, reintegrations and compression filling were the basis on which it was proceeded to the stages of cleaning and consolidation of the stone and patina base. Special installations, such as anti-humidity barrier and a pigeon repellent system, which will avoid their nest building, have been incorporated.

    La puerta de los Apóstoles de la Catedral de Valencia, edificada en la primera mitad del s. XIV, constituye uno de los ejemplos más sobresalientes de las portadas monumentales del gótico meridional. La intervención realizada fue fruto de un convenio de mecenazgo entre empresas e instituciones, y destinada a ejecutar obras de conservación sobre la fábrica, degradada por el mal funcionamiento constructivo, y las esculturas, reponiendo mediante réplicas las de los apóstoles retiradas hace treinta años. Un conjunto de operaciones constructivas, desde el vaciado de la terraza del falso triforio a retacados y reintegraciones, fueron la base para proceder a fases de limpieza y consolidación del soporte de piedra y pátinas. Fueron incorporadas instalaciones especiales como una barrera antihumedad y un sistema para alejamiento de palomas, que evitará que aniden y que depositen sus excrementos.

  5. Large-scale Mass Transport Deposits in the Valencia Basin (Western Mediterranean): slope instability induced by rapid sea-level drawdown?

    2014-05-01

    The Messinian Salinity Crisis (MSC) strongly affected the physiography of the Mediterranean margins at the end of the Miocene. The sharp sea-level fall gave a new configuration to the Mediterranean basin and created dramatic morphological and sedimentological changes: margins have been largely eroded whereas the deep basins accumulated thick evaporitic and detrital units. Amongst these detrital units, there are evidences on seismic reflection data for major large-scale slope failure of the Mediterranean continental margins. About 2700 km of seismic reflection profiles in the southwestern part of the Valencia Basin (Western Mediterranean) have enabled us the detailed mapping of distinctive Messinian erosional surfaces, evaporites and deep detrital deposits. The detrital deposits occur in a distinct unit that is made of chaotic, roughly-bedded or transparent seismic bodies, which have been mainly mapped in the basin domain. Locally, the seismic unit shows discontinuous high-amplitude reflections and/or an imbricate internal structure. This unit is interpreted to be formed by a series of Mass Transport Deposits (MTDs). Rapid drawdown has long been recognized as one of the most severe loadings conditions that a slope can be subjected to. Several large historical slope failures have been documented to occur due to rapid drawdown in dams, riverbanks and slopes. During drawdown, the stabilizing effect of the water on the upstream face is lost, but the pore-water pressures within the slope may remain high. The dissipation of these pore pressures in the slope is controlled by the permeability and the storage characteristics of the slope sediments. We hypothesize that the MTDs observed in our data formed under similar conditions and represent a large-scale equivalent of this phenomenon. Therefore, these MTDs can be used to put some constraints on the duration of the drawdown phase of the MSC. We have performed a series of slope stability analysis under rapid Messinian sea

    Full Text Available Abundance and distribution of the Iberian hare (Lepus granatensis Rosenhauer, 1856 in the Sierra de Mariola Natural Park (Alicante-Valencia The Iberian hare (Lepus granatensis Rosenhauer, 1856 is a species of great value in Spanish Mediterranean ecosystems for several reasons, such as its interest to hunters, its contribution to soil fertility and plant diversity, and its role as prey. However, factors such as fragmentation, degradation and loss of habitat and diseases, predation and high pressure hunting are having a detrimental effect on the conservation of the species. It is therefore of interest to determine the abundance and distribution of the Iberian hare in areas of the peninsula where there are insufficient data to establish guidelines for conservation and sustainable management of hare populations in the peninsula. Our goal was to assess the abundance and distribution of the Iberian hare in the most widely used areas of a mountainous Mediterranean landscape in the Iberian peninsular (Mariola Mountain Park, located between the provinces of Alicante and Valencia. Data obtained from studies conducted in transects from 2008 to 2010 showed that intra-annual abundance was highest in spring (KIA half of 0.26 hares/km and lowest in winter (average 0.075 KIA hares/km. As to their preferences in relation to land use, abundance was highest in the matrix of dry groves (KIA half of 0.33 hares/km and irrigated groves (average 0.2 KIA hares/km. The matrix of natural vegetation and agricultural abandonment had low numbers of hares, with values of 0.083 and 0.033 hares/km, respectively.

The bridge has 6 spans, each 20 m long, and two half circular vaults, of 5 m diameter, at each end of the bridge. The bridge had to maintain its present span arrangement, since it has been widened only on one side. The sinking of piles, and the building of the span supports was completed in six months. The 20 m span beams, on which the reinforced concrete bridge slab rests were to be cast at the site, but after careful study by the site management engineer and the contractors it was decided to built them on the river bed, and lift them by means of a crane, to shorten the construction time. This saves time, and made it unnecessary to close the traffic over the existing bridge; an important factor, since the bridge connects the roads from Valencia, Barcelona and Alicante. The mean time taken in attaching, lifting and placing each beam was 18 minutes.El proyecto comprende el ensanche del puente actual de 15 m de anchura a 31,60 m, quedando con dos vías de 10,40 m, dos andenes de 2,40 m, dos zonas de protección de 0,50 m cada una y una mediana de 5 m. La sección longitudinal consta de seis vanos de 20 m de luz y dos bóvedas de medio punto de 5 m de diámetro situadas en las embocaduras. Había que darle al puente las mismas características actuales, puesto que el ensanche se hace por un solo lado. Pilotaje y alzado de pilas quedaron terminados en 6 meses. Las vigas de 20 m de luz sobre las que apoya el tablero de hormigón armado se preveía debían construirse in situ; pero estudiado conjuntamente por la Dirección de Obra y Empresa Constructora, se determinó prefabricarlas en el lecho del río y elevarlas con grúa para reducir el plazo de ejecución.

Tras una revisión teórica sobre el concepto y el análisis de los factores que incitan a realizar esta práctica en el contexto educativo actual, se elabora una encuesta ad hoc dirigida al alumnado de los primeros cursos del Grado de Traducción e Interpretación de la Universidad Internacional de Valencia (VIU para analizar cómo utilizan la propiedad intelectual ajena en el desarrollo de sus actividades académicas. De los resultados alcanzados se desprende que los estudiantes (n=73 todavía no tienen muy claro cómo y cuándo referenciar sus fuentes bibliográficas y, para ello, necesitan formación. En ocasiones no recurren al ciberplagio deliberadamente, sino de manera involuntaria, ya que no son conscientes de ello. Desconocen la verdadera limitación del término, las normas del centro en materia de ciberplagio y las sanciones que deben aplicarse. De ahí que sea necesario tomar medidas urgentes dirigidas no solo a enseñarles la importancia de hacer un uso honesto de la información disponible en red, sino a intentar desarrollar su competencia informacional, lo que les permitirá transformar la información que manejan en conocimiento. ABSTRACT: This paper presents the results of a research work carried out on cyber-plagiarism in university online language teaching and translation training.

In molte città contemporanee, la ristrutturazione economica e la riqualificazione urbana posto gli eventi al centro delle strategie di cambiamento.Spesso, tuttavia, questi interventi richiedono un tempo molto breve e investimenti elevati, che non sempre hanno un effetto duraturo nel tempo, con edifici e spazi che, dopo l'evento, si trasformano in spazi pubblici inutilizzati o edifici che devono essere riqualificati.Le città costiere rappresentano un campo privilegiato di analisi per approfondire le dinamiche dei processi di sviluppo e di rigenerazione connessi ad eventi.Alcune città hanno potenziato la propria identità marittima sviluppando attività legate alla vela, eventi sportivi velici e la nautica da diporto, promuovendo la crescita sociale ed economica, nonché la riqualificazione delle aree dismesse. Il recupero di questa identità è il punto di partenza per migliorare la qualità urbana e attrarre grandi eventi, sviluppando la competitività in un circolo virtuoso.L'immagine di queste città è migliorata, a livello locale, nazionale e internazionale, promuovendo processi di riqualificazione che hanno coinvolto i responsabili politici, gli utenti della città e gli stakeolders.Nei casi di successo, i grandi e i piccoli eventi rappresentano tessere di un mosaico più ampio, una visione della città fondata sulla identità marittima e il progetto di riqualificazione del waterfront è stato in grado di rafforzare le relazioni con le aree urbane esistenti.Il saggio propone due casi di studio europei, le città di Lorient e Valencia, mettendo in evidenza il ruolo della pianificazione a lungo termine nei processi di rigenerazione.La città di Lorient, in linea con la sua storia, ha iniziato un processo di rigenerazione

    With the purpose of evaluating nutritional status in a group of preschoolers attending a public day care center in Valencia, Venezuela (2002), a research was made for social stratus, anthropometric variables; weight, height and arm circumference, hemoglobin, seric retinol, presence of parasitosis and food consumption, as well as the mother's educational level. The program SPSS 11.0 and the t Student, ANOVA Post Hoc from Bonferroni and Fisher (p education, while only 9.8% of the mothers in poverty had reached that level. According to the Z values (H/A, W/H and AC/H), high percentages under -1.00 were observed (27.3%, 25.6% and 24.5%, respectively). The W/H and AC/H of children of mothers studying in a university presented discrepancies when compared with children of mothers with a primary educational level. A 25.9% of anemia was presented, and there were differences between anemic and non-anemic groups for H/A and AC/H. Protozoaries were observed in 61.0%, helmintos in 16.9% and both in 22.1%. There was a 2.6 times higher risk of presenting nutritional deficiency for AC/H in the group found with parasites. An adequate consumption of energy and iron was found, with an excessive consumption of proteins and vitamin A. It is concluded that there exists a nutritional risk evaluated through hematologic parameters, the presence of parasitosis and social stratus.

  18. The biology and ecology of Valencia letourneuxi Sauvage 1880 (Valenciidae - Prospects for conservation

    Full Text Available Data are provided on the distribution, abundance, early development and biology of the endangered Greek endemic species Valencia letourneuxi Sauvage 1880, along with a record of its occurrence at new localities. V. letourneuxi is a small-bodied and short-lived insectivorous species, exhibiting cryptic colouration and sexual dimorphism. It matures in the first year of life, reproduces serially in late spring and summer, and deposits spherical eggs, around 2 mm, on aquatic plants. Most morphometric characters show size-specific trends, which complicate comparisons among populations or with other species. Of specific systematic importance is the relative position of the anal and dorsal fins, which remains almost unaltered throughout development, and allows safe distinction from A. fasciatus. The species was found mostly in deep areas with clean and slow running water, usually associated with freshwater springs. Rich submerged vegetation is the prominent ecological feature of all sites in which the species was found. Using as criteria of rarity the limited geographic distribution, the confinement of the species in few localities of each aquatic system and the low local densities, V. letourneuxi can be characterised as a "restricted and locally rare species". The restricted distribution, coupled with the narrow ecological requirements, makes the species vulnerable to extinction. Its disappearance from at least four aquatic systems and the serious population decline in a number of other systems seems to be connected with habitat loss or degradation caused by human activities. The prospects of conservation are discussed.

    This study aimed at identifying the factors that contribute to delaying the access of alcohol abuse patients to specific treatment centres in the Autonomous Region of Valencia (Spain). 563 patients from Addictive Behaviours Units (UCA) and Alcohology Units (UA) were interviewed. A survey was conducted which included items on previous requested treatment in other centres and on barriers of accessibility to treatment in specific ambulatory centres. A descriptive analysis and t-student and ANOVA with Scheffé post-hoc tests were carried out. 59.7% of respondents said they had requested previous treatment in non-specific resources due to physical or psychical trouble that they now relate to their alcohol use although they did not do so at the time, in addition to being motivated by their own alcohol abuse (42.8%). The most attended resources were Primary Care and Specialist Unit Care. Women showed a higher demand for treatment in Mental Health Services (p gender differences in barriers that delay access to treatment do exist. It is necessary to build gender-adapted intervention guidelines to be used in Primary Care and Mental Health services to reduce the accessibility barriers to treatment.

    The aim of our study was to assess nutritional intake and anthropometric statuses in schoolchildren to subsequently determine nutritional adequacy with Spanish Dietary Reference Intake (DRIs). The ANIVA study, a descriptive cross-sectional study, was conducted in 710 schoolchildren (6-9 years) in 2013-2014 in Valencia (Spain). Children's dietary intake was measured using 3-day food records, completed by parents. Anthropometric measures (weight and height) were measured according to international standards, and BMI-for-age was calculated and converted into z-scores by WHO-Anthro for age and sex. Nutrient adequacy was assessed using DRI based on estimated average requirement (EAR) or adequate intake (AI). Pearson's chi-square and Student's t-test were employed. Of our study group (47.61% boys, 52.39% girls), 53.1% were normoweight and the weight of 46.9% was inadequate; of these, 38.6% had excess body weight (19.6% overweight and 19.0% obesity). We found intakes were lower for biotin, fiber, fluoride, vitamin D (p nutritional adequacy to Spanish recommendations in overweight children. Our findings suggest that nutritional intervention and educational strategies are needed to promote healthy eating in these children and nutritional adequacies.

    Children with autism spectrum disorder (ASD) have been found to have alterations in dietary fat intake and fat quality. The fat intakes of the foods consumed by children with and without ASD were compared, and the deficiency and excess of these nutrients were examined. In a matched case-control study, 3-day food diaries were completed by 105 children with ASD and 495 typically developing (TD) 6- to 9-year-old children in Valencia (Spain). We used the probabilistic approach and estimated average requirement cut-point to evaluate the risk of inadequate nutrients intakes. These were compared between groups and with Spanish recommendations using linear and logistic regression, respectively. Groups did not differ significantly in age, total dietary intake, Healthy Eating Index, or food variety score. Children with ASD had lower saturated fatty acids (SFAs) and ω-3 polyunsaturated fatty acids (PUFAs) intakes, but their total PUFAs and (PUFAs + monounsaturated fatty acids (MUFAs)/SFAs, PUFAs/SFAs intakes and ω-6/ω-3 ratios were higher than TD children. The total fat and cholesterol intakes of both groups were slightly above Spanish recommendations. Both groups had low ω-6 intakes, very low ω-3 intakes, and high ω-6/ω-3 ratios. Further research is required to clarify associations between ASD symptomatology, fat-eating patterns and health status.

    Nowadays one of the main priorities for metro line operators is the reduction of energy consumption, due to the environmental impact and economic cost. In order to achieve this objective different strategies can be applied, normally focused into rolling stock, infrastructure and/or operation. Considering short-term measures and related to the traffic operation strategies, different approaches are being researched. One of the most effective strategy which reduce net energy consumption is the use of efficient driving techniques. These techniques produces a speed profile between two stations that requires the minimum net energy consumption, without degrading commercial running times or passenger comfort. In this paper, a computer model for calculating the metro vehicles speed profiles minimizing the energy consumption was developed. The equations considered in the model represent the behavior of a single vehicle operated under manual driving, subject to different constraints such as the headway, cycle time, distances and acceleration limits. The proposed model calculates different commands to be systematically executed by the driver. The resulting simulator has been tuned by means of on board measurements of speed, accelerations and energy consumption obtained along different lines in Metro de Valencia network. For this purpose, different scenarios are analyzed to assess the achievable energy savings. In general terms and comparing with the actual energy consumption, the solutions proposed can reduce the net energy consumption around 19%. (Author)

    Full Text Available La realidad social, en constante proceso de cambio, exige al sistema educativo un esfuerzo por actualizar las respuestas educativas frente a la mejora de la convivencia. Es en este contexto en el que la mediación ha dejado ver sus potencialidades educativas, ya que influye sobre la mejora del individuo, de las relaciones interpersonales y del clima escolar. No obstante, son escasas las investigaciones orientadas a conocer el impacto de la misma. En este artículo presentamos un estudio dirigido a conocer la valoración de la mediación atendiendo a las opiniones del alumnado de cinco centros educativos de secundaria de Valencia y cuatro de Castellón. Asimismo, se pretende detectar si existen diferencias significativas entre las valoraciones ofrecidas en ambas provincias. Para el logro de estos objetivos se ha recogido información de 1043 estudiantes a través de un cuestionario elaborado ad hoc. Mediante un estudio descriptivo-inferencial destacamos como resultado el gran acuerdo que existe por parte del alumnado participante en valorar de forma muy positiva la mediación. Como aspectos mejorables, se detecta la necesidad de difundir en los centros la información sobre sus servicios de mediación, formar en mediación a todo el alumnado y ampliar las funciones de la mediación a aquellos conflictos más relacionados con las tareas de enseñanza y aprendizaje y con las relaciones entre el alumnado y el profesorado. Finamente, se observa que, en general, la satisfacción sobre la mediación es menor en Valencia que en Castellón. En conclusión, el estudio refleja que la mediación escolar es considerada como ventajosa para el alumnado y como una oportunidad que le facilita la gestión de sus propios conflictos, si bien hay aspectos en los que se debe trabajar para la mejora de la convivencia y la configuración de una ciudadanía democrática.

    Lake eutrophication is a critical issue in the interplay of water supply, environmental management, and ecosystem conservation. Integrated sensing, monitoring, and modeling for a holistic lake water quality assessment with respect to multiple constituents is in acute need. The aim of this paper is to develop an integrated algorithm for data fusion and mining of satellite remote sensing images to generate daily estimates of some water quality parameters of interest, such as chlorophyll a concentrations and water transparency, to be applied for the assessment of the hypertrophic Albufera de Valencia. The Albufera de Valencia is the largest freshwater lake in Spain, which can often present values of chlorophyll a concentration over 200 mg m(-3) and values of transparency (Secchi Disk, SD) as low as 20 cm. Remote sensing data from Moderate Resolution Imaging Spectroradiometer (MODIS) and Landsat Thematic Mapper (TM) and Enhance Thematic Mapper (ETM+) images were fused to carry out an integrative near-real time water quality assessment on a daily basis. Landsat images are useful to study the spatial variability of the water quality parameters, due to its spatial resolution of 30 m, in comparison to the low spatial resolution (250/500 m) of MODIS. While Landsat offers a high spatial resolution, the low temporal resolution of 16 days is a significant drawback to achieve a near real-time monitoring system. This gap may be bridged by using MODIS images that have a high temporal resolution of 1 day, in spite of its low spatial resolution. Synthetic Landsat images were fused for dates with no Landsat overpass over the study area. Finally, with a suite of ground truth data, a few genetic programming (GP) models were derived to estimate the water quality using the fused surface reflectance data as inputs. The GP model for chlorophyll a estimation yielded a R(2) of 0.94, with a Root Mean Square Error (RMSE) = 8 mg m(-3), and the GP model for water transparency estimation using

    Coastal wetlands, despite the importance of their environmental and ecological functions, are areas that suffer of great pressures. Most of them are produced by the rapid development of the surrounding artificial landscapes. Socio-economic factors such as population growth and urban-industrial surfaces expansion introduce pressures on the nearby environment affecting the quality of natural and agricultural landscapes. The present research analyses interconnections among landscapes (urban, agricultural and natural) under the hypothesis that urban-artificial impacts could be detected on soils of an agro-ecological protected area, L'Albufera de Valencia, Natural Park, located in the vicinity or the urban area of the City of Valencia, Spain. It has been developed based on Environmental Forensics criteria witch attend two types of anthropogenic pressures: (1) direct, due to artificialization of soil covers that produce anthropogenic soil sealing, and (2) indirect, which are related to water flows coming from urban populations throw artificial water networks (sewage and irrigation systems) and that ultimately will be identified by the presence of o emerging-pharmaceuticals contaminants in soils of the protected area. For the first case, soil sealing a methodology based on temporal comparison of two digital layers for the years 1991 and 2011 applying Geographical Information Systems and Landscapes Metrics were undertaken. To determine presence of emerging contaminants 15 soil samples within the Natural Park were analyzed applying liquid chromatography tandem mass spectrometry for the detection of 17 pharmaceutical compounds. Results show that both processes are present in the Natural Park with a clear geographical pattern. Either soil sealing or detection of pharmaceuticals are more intensive in the northern part of the study area. This is related to population density (detection of pharmaceuticals) and land cover conversion from agricultural and natural surfaces to

    Full Text Available Urban renovation projects, which have led to the conversion of port areas through a new vision of waterfronts as elements of the potential development of the urban system in its entirety, have spread since the early 1950s and now some port cities are able to trigger some mechanisms which, even if they are the result of some processes that have been activated for decades and which are still evolving, are able to amplify and to extend over time their generated positive impacts. These impacts also produce a system of relations in the context of the hinterland, attracted also by policies of economic, social, and cultural development. In the case of the city of Valencia, we have seen, in the last 50 years, a progressive spread of the urbanized area to the coasts, simultaneously with a process of renovation of the port area, which has been populated by important architectures, and which has been equipped by efficient infrastructures and subjected to numerous recovery and restoration operations of its historic buildings. However, the environmental conditions near the port area are not well suited to a good quality of life because ports are pollution producers, sites of urban decay, and of social degradation. A good plan can include some instruments to decrease those negative factors, leading to a close merging between the port area and the city hinterland, and generating new economies. The proposal of this research consists in a method of integrating the port planning with an environmental accounting system.

    This paper proposes a method of valuing the stock of residential buildings in Spain as the first step in assessing possible damage caused to them by natural hazards. For the purposes of the study we had access to the SIOSE (the Spanish Land Use and Cover Information System), a high-resolution land-use model, as well as to a report on the financial valuations of this type of buildings throughout Spain. Using dasymetric disaggregation processes and GIS techniques we developed a geolocalized method of obtaining this information, which was the exposure variable in the general risk assessment formula. If hazard maps and risk assessment methods - the other variables - are available, the risk value can easily be obtained. An example of its application is given in a case study that assesses the risk of a landslide in the entire 23 200 km2 of the Valencia Autonomous Community (NUT2), the results of which are analyzed by municipal areas (LAU2) for the years 2005 and 2009.

    To determine, through the use of a structural equation model, the relationships that exist between physical activity, body fat, perceived physical ability, and three indicators of psychological well-being, in a sample of Spanish university students. A descriptive cross-sectional study of 639 students 18-29 years of age representative of the universities of Valencia, Spain, during the 2005-2006 term. Physical exercise was rated by taking an inventory of healthy behaviors among students. The following scales were applied: self-perceived physical ability, self-esteem, satisfaction with life, and subjective vitality. Body fat was expressed as the percentage of fat mass (PFM). A theoretical model was devised using six measured variables. The participants' level of physical activity was moderate; they perceived themselves to be physically competent; had high self-esteem; were satisfied with life; and had high vitality. Physical activity was negatively correlated with PFM in men and women alike; and negatively associated with perceived physical ability; while perceived physical ability was positively associated with self-esteem, life satisfaction, and subjective vitality. The effect of physical activity on perceived competence was mediated in part by PFM in men. In women, exercise was directly correlated to PFM, as well as perceived ability, without PFM mediation. Increased physical activity is of great value to public health because, in addition to helping to reduce body fat, it improves psychological well-being and self-image.

Se trata de una pieza de grandes dimensiones (150x160x160 cm, labrada en soporte pétreo, concretamente mármol de Carrara. La pieza presentaba una importante fracturación del fuste, que ponía en riesgo su permanencia, por lo que se hacía indispensable un exhaustivo diagnóstico del material y un sistema de refuerzo estructural. Este tratamiento se realizó atendiendo al difícil problema de tamaño, peso y emplazamiento de la propia obra, por lo que se diseñó una estructura de sostén móvil que desplazara el tazón y elevara el conjunto por medio de dispositivos hidráulicos. Ello permitió intervenir en la fuerte fragmentación del fuste y proporcionar estabilidad y solidez material a la obra. Asimismo, se diseñó una estructura de sacrificio reversible, como medida preventiva, que permitía restablecer su funcionalidad y garantizar la estabilidad del material original. En definitiva, este proyecto ha permitido recuperar una obra única y verdadero ejemplo de valor excepcional. La obra fue intervenida en el laboratorio de conservación y restauración de Materiales Pétreos y Ornamentales del Instituto Universitario de Restauración del Patrimonio de la Universidad Politécnica de Valencia.

    Full Text Available The musical activity in the cathedral of Valencia before the XVIth century is quite unknown. This study seeks to advance the knowledge of this subject focusing on the groups of people carrying out the different trades with responsibility in the organization and the musical practice between 1480-1505. This period comprises treatise writer Guillem de Podio’s chant schools mastery in the above mentioned cathedral. The perspective offered here is provided by the prosopography, using data from this institution, other cathedrals and documental sources with different features like notarial, diocesan and those preserved in civil and royal archives. On the other hand, this work has also allowed enough evidence to be presented to dismiss the current identification hypothesis between the composer Juan Rodríguez de Sanabria and the singer of Isabella I of Castile, Juan Rodríguez de la Torre. A prosopographical catalogue of all of the studied individuals is included in an appendix.

    Full Text Available Mesmo com a grande relevância dos portos para o desenvolvimento econômico e social dos países, há uma questão que merece atenção dos gestores e da sociedade, é o fato que as atividades portuárias causam impactos ambientais, tais como assoreamento em meios aquáticos, alterações na fauna e flora, emissões atmosféricas, geração de resíduos sólidos, entre outros. Neste contexto, a gestão da informação ambiental é importante tanto para os gestores dos portos quanto para a sociedade, pois permite conhecer o nível de impacto gerado e o nível de sustentabilidade ao longo do tempo. Uma das formas de medir a informação é verificar o nível de comprometimento dos gestores com a gestão ambiental. Como conseqüência deste entendimento, a presente pesquisa visa identificar o nível de sustentabilidade ambiental na Autoridade Portuária de Valencia (APV.

    Preventive conservation requires monitoring and control of the parameters involved in the deterioration process, mainly temperature and relative humidity. It is important to characterise an archaeological site prior to carrying out comparative studies in the future for preventive conservation, either by regular studies to verify whether the conditions are constant, or occasional ones when the boundary conditions are altered. There are numerous covered archaeological sites, but few preventive conservation works that give special attention to the type of cover installed. In particular, there is no background of microclimatic studies in sites that are in the ground and, as in the Plaza de l’Almoina (Valencia, Spain), are buried and partially covered by a transparent roof. A large effect of the transparent cover was found by the sensors located below this area, with substantial increases in temperature and a decrease in the relative humidity during the day. Surrounding zones also have values above the recommended temperature values. On the other hand, the influence of a buried water drainage line near the site is notable, causing an increase in relative humidity levels in the surrounding areas. Multivariate statistical analyses enabled us to characterise the microclimate of the archaeological site, allowing future testing to determine whether the conservation conditions have been altered.

    The toxic effects of waters collected from irrigation channels in a Mediterranean wetland (Albufera Natural Park, Valencia, Spain) were tested with the Microtox assay and compared with six pollution indices (PIs) defined from analytical parameters. Chemical oxygen demand (COD), biological oxygen demand (BOD), nutrients, heavy metals and pesticides were measured. The bioassay result (concentrations of the water sample (% V/V) that reduced light emission to 10%, 20% and 50%, EC10, EC20 and EC50, respectively (ECs)) was compared with the PIs. This comparison has demonstrated a general agreement between ECs and PIs, except in the case of irrigation channels affected by herbicides used in rice farming (molinate and thiobencarb). No pronounced inhibition was detected in the bioluminescence in relation to the eutrophic parameters in the irrigation waters for EC50 values, indicating that this parameter does not suffice to detect eutrophic waters. Data derived from irrigation water pollution and bioassay were assembled by multivariate statistical techniques (principal component analysis). These components were associated with various contamination sources.

    This article focuses on the conceptions, attitudes and practices of the inhabitants from four villages (veredas) in Tierralta and Valencia (Cordoba, Colombia), who have suffered from or are aware of the existence of cutaneous leishmaniasis. A mixed methodology was implemented based in a qualitative design using interviews and focus groups (n=45) and an epidemiological design which included applying the Montenegro test (n=251), uncovering suspected cases of cutaneous leishmaniasis in humans, (n=5) and applying epidemiological surveys (n=409). Among the results, a lack of knowledge regarding the vector was found; although respondents could identify the Lutzomyia (known as "alú"), they did not correlate it with cutaneous leishmaniasis. In addition, traditional home treatments were more frequently used, increasing the underrecording of cases. With respect to healthcare personnel, flaws in diagnosis and treatment were found, which reinforces adherence to home treatments. This scenario calls for a reflection upon the challenges of the health care system in relation to the interventions of health personnel in communities situated in endemic areas.

MÉTODOS: Estudio transversal descriptivo en 639 estudiantes de 18 a 29 años representativos de las universidades de Valencia, España, en el curso 2005-2006. La práctica de actividad física se evaluó mediante el inventario de conductas de salud en escolares. Se aplicaron las escalas de competencia física percibida, autoestima, satisfacción con la vida y vitalidad subjetiva. La adiposidad corporal se expresó mediante el porcentaje de masa grasa (PMG. Se elaboró un modelo teórico con las seis variables medidas. RESULTADOS: El nivel de actividad física de los participantes era moderado, se percibían físicamente competentes, tenían una alta autoestima, se encontraban satisfechos con su vida y se sentían con alta vitalidad. La actividad física se relacionó negativamente con el PMG tanto en los varones como en las mujeres; el PMG se asoció negativamente con la percepción de competencia física; y la competencia física percibida se asoció positivamente con la autoestima, la satisfacción con la vida y la vitalidad subjetiva. El efecto de la práctica de actividad física sobre la competencia percibida estaba mediado parcialmente por el PMG en los varones; en las mujeres, la práctica de actividad física se relacionó directamente tanto con el PMG como con la percepción de competencia, sin la mediación del PMG.

    We describe the performance of a microclimate monitoring system that was implemented for the preventive conservation of the Renaissance frescoes in the apse vault of the Cathedral of Valencia, that were restored in 2006. This system comprises 29 relative humidity (RH) and temperature sensors: 10 of them inserted into the plaster layer supporting the fresco paintings, 10 sensors in the walls close to the frescoes and nine sensors measuring the indoor microclimate at different points of the vault. Principal component analysis was applied to RH data recorded in 2007. The analysis was repeated with data collected in 2008 and 2010. The resulting loading plots revealed that the similarities and dissimilarities among sensors were approximately maintained along the three years. A physical interpretation was provided for the first and second principal components. Interestingly, sensors recording the highest RH values correspond to zones where humidity problems are causing formation of efflorescence. Recorded data of RH and temperature are discussed according to Italian Standard UNI 10829 (1999). PMID:22164100

    The use of the stable hydrogen and carbon isotope ratios of fermentative ethanol as suitable environmental fingerprints for the regional origin identification of red wines from Valencia (Spain) has been explored. Monovarietal Vitis vinifera L. cvs. Bobal, Tempranillo, and Monastrell wines have been investigated by (2)H NMR and (13)C IRMS for the natural ranges of site-specific (2)H/(1)H ratios and global delta(13)C values of ethanol over three vintage years. Statistically significant interregional and interannual (2)H and (13)C abundance differences have been noticed, which are interpreted in terms of environmental and ecophysiological factors of isotope content variation. Multivariate discriminant analysis is shown to provide a convenient means for integration of the classifying information, high discriminating abilities being demonstrated for the (2)H and (13)C fingerprints of ethanol. Reasonable differentiation results are achieved at a microregional scale in terms of geographic provenance and even grapevine genotypic features.

    Full Text Available Present-day economical crisis resembles partly that one suffered in Spain at the beginning of the 17th century. In those days, the Spanish Crown, which like all modern States had needed to carry out new functions such as deciding the ell into a deep economic crisis. Many treatises and discourses, several of them addressed to the king Philip III were written to change the economic policy of the State, which was considered responsible for the evils affecting Spain. Some of these texts have been studied by the historians of economics, but not by the historians of education, however they can be, in our opinion, included in that literary genre whose objective was the education of the princes. In this work we will analyse the writings dedicated to that king by the Spanish humanist Pedro de Valencia with the aim of educating the rulers of the Monarchy so that they could acquire the necessary intellectual and moral virtues to accomplish their duties. There are in his texts many teachings that are still valid nowadays.La crisis económica actual tiene ciertos paralelismos con la que sufrió España en el comienzo del siglo XVII. En aquel tiempo, la Corona española, que como todos los Estados modernos para poder consolidarse había tenido necesidad de cumplir nuevas funciones como las de decidir la política fiscal y la monetaria, entró en una profunda crisis económica. Con la intención de cambiar la política económica del Estado, a la que se hacía responsable de los males que aquejaban a España, se redactaron multitud de discursos y tratados, muchos de los cuales se dirigieron directamente al rey Felipe III. Algunos de estos escritos han sido estudiados por los historiadores de la economía, pero no por los de la educación, a pesar de que, según nuestra opinión, pueden incluirse dentro del género de literatura que tenía como objetivo la educación de los príncipes.

    Full Text Available Despite the progress in the fetal echocardiographic detection of congenital critical heart defects and neonatal physical examination, a significant number of newborn infants are discharged and readmitted to the hospital in severe condition due to cardiac failure or collapse. The aim of this study was to assess the incidence of undetected critical congenital heart disease (CCHD by a pulse oximetry-screening program in the maternity wards of hospitals with Perinatal Services in a specific geographic area. This is a prospective observational study performed in in the health area corresponding to the city of Valencia. Eligible infants were consecutively admitted newborn infants in the maternities of the participating hospitals with negative fetal echocardiography after normal physical examination in the delivery room. All patients were screened following a specific pulse oximetry protocol before discharge. A total of 8856 newborn infants were screened. A total of three babies presented with severe congenital cardiac malformation and two babies presented with early onset sepsis. Sensitivity was 100% and specificity was 99.97%, with a positive predictive value of 60% and negative predictive value of 100%. Pulse oximetry screening programs in the early neonatal period constitute a valuable tool to avoid inadvertent hospital discharge of severe cardiac malformations and the subsequent life-threatening complications derived.

    Anastrepha serpentina (Wiedemann) (Diptera: Tephritidae) is sporadically captured in the Rio Grande Valley of Texas. Although its preferred hosts are in the Sapotaceae family, several varieties of Citrus, including grapefruit and oranges are listed as alternate hosts. Although Mexican fruit fly, Anastrepha ludens (Loew), is known to be a major pest of Citrus, doubt exists as to the status of Citrus as a breeding host for A. serpentina. To evaluate the host status of commercial Citrus for A. serpentina we compared oviposition and development with that of A. ludens under laboratory conditions with 'Rio Red' grapefruit (Citrus paradisi MacFayden) and 'Valencia' oranges [Citrus sinensis (L.) Osbeck] in different stages of maturity. Both fly species oviposited in early season fruit in which the eggs and larvae died in the fruit albedo. Survival of either species to the adult stage occurred in later season grapefruit. In oranges, no A. serpentina larvae survived compared with 150 A. ludens surviving to adults. Survival on both Citrus species was much lower for A. serpentina, only approximately 5% of eggs eclosed into larvae in grapefruit compared with approximatley 50% for A. ludens. In oranges approximately 16% of A. serpentina eggs eclosed compared with approximately 76% for A. ludens. In grapefruit, only one fourth as many A. serpentina larvae survived to the adult stage compared with A. ludens. Additional experiments were performed in a greenhouse on small, caged trees of la coma (Sideroxylon celastrinum H.B.K.), a Texas species of Sapotaceae. The A. serpentina females readily oviposited into these berries and normal adults emerged. The present low incidence of the adults, coupled with the high mortality during development of the larvae, suggests that Texas citrus is unlikely to support a breeding population of A. serpentina.

    A simplified two-dimensional eutrophication model was developed to simulate temporal and spatial variations of chlorophyll-a in heavily regulated coastal lagoons. This model considers the hydrodynamics of the whole study area, the regulated connexion of the lagoon with the sea, the variability of the input and output nutrient loads, the flux from the sediments to the water column, the phytoplankton growth and mortality kinetics, and the zooplankton grazing. The model was calibrated and validated by applying it to the Albufera of Valencia, a hypertrophic system whose connection to the sea is strongly regulated by a system of sluice-gates. The calibration and validation results presented a significant agreement between the model and the data obtained in several surveys. The accuracy was evaluated using a quantitative analysis, in which the average uncertainty of the model prediction was less than 6%. The results confirmed an expected phytoplankton bloom in April and October, achieving mean maximum values around 250 μg l(-1) of chlorophyll-a. A mass balance revealed that the eutrophication process is magnified by the input loads of nutrients, mainly from the sediments, as well as by the limited connection of the lagoon with the sea. This study has shown that the developed model is an efficient tool to manage the eutrophication problem in heavily regulated coastal lagoons. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available The current biography of Mateo Flecha the Elder, the most outstanding composer of the Spanish genre of the ensalada, has been based on a few confi rmed data. As a result, there are big gaps in his known professional career. In this article, documents about his presence in the City of Valencia, as chapel master of the cathedral in two periods (1526-1531? and 1539-1541, are presented for the fi rst time. From them, his stay in the cathedral and some questions about his identity are studied. In order to know better the background where Flecha developed his principal activity, certain musical aspects of the Valencian cathedral are analyzed during the period included between the fi rst and last year of his presence in this institution (1526-1541. Finally, new ideas are presented, on account of the information now presented, that could add to the already raised ones about the opened issue on the creative context of some of his ensaladas.

    In Citrus the inhibitory effect of fruit on flower formation is the main cause of alternate bearing. Although there are some studies reporting the effect on flowering of the time of fruit removal in a well-defined stage of fruit development, few have investigated the effect throughout the entire fruit growth stage from early fruitlet growth to fruit maturity. The objective of this study was to determine the phenological fruit developmental stage at which the fruit begins its inhibitory effect on flowering in sweet orange by manual removal of fruits, and the role of carbohydrates and nitrogen in the process. Fruit exerted its inhibitory effect from the time it was close to reaching its maximum weight, namely 90% of its final size (November) in the present experiments, to bud sprouting (April). The reduction in flowering paralleled the reduction in bud sprouting. This reduction was due to a decrease in the number of generative sprouted buds, whereas mixed-typed shoots were largely independent of the time of fruit removal, and vegetative shoots increased in frequency. The number of leaves and/or flowers per sprouted shoot was not significantly modified by fruit load. In 'Valencia' sweet orange, fruit inhibits flowering from the time it completes its growth. Neither soluble sugar content nor starch accumulation in leaves due to fruit removal was related to flowering intensity, but some kind of imbalance in nitrogen metabolism was observed in trees tending to flower scarcely.

    Serum uric acid has been reported to be a risk factor for cardiovascular disease (CVD). The objective of the present work was to determine the prevalence of hyperuricemia in a large size sample of a healthy male population, as well as the association between uric acid and other cardiovascular risk factors. A cross-sectional study was conducted in a randomly selected sample of 1,564 healthy men in Valencia (Spain), aged 20-67 years, working in the automobile industry. Serum values of uric acid, cholesterol, and glucose were obtained, as well as blood pressure and body mass index measurements. An assessment was made of socio-economic data, drug therapy, and smoking. The overall prevalence of hyperuricemia was 5.10%; it increased with age. A marked increase (p < 0.01) of hyperuricemic individuals was observed with increased prevalence of other cardiovascular risk factors (from 1.8% with hyperuricemia alone up to 28% among individuals with four simultaneous risk factors). By means of a multivariate logistic regression analysis, the OR of hyperuricemia associated with each factor were calculated: increased serum glucose was the variable with a stronger association (OR: 2.69; 95%CI: 1.21-5.99), obesity ranking next (OR: 2.50; 95%CI: 1.42-4.49). Statistically significant associations were also observed for increased serum cholesterol, increased blood pressure, and smoking. The prevalence of hyperuricemia varies with the simultaneous presence of other classical cardiovascular risk factors. Even in this healthy mediterranean population, uric acid is significantly associated with several components in the plurimetabolic syndrome.

  10. Extreme Mesozoic crustal thinning in the Eastern Iberia margin: The example of the Columbrets Basin (Valencia Trough)

    Eastern Iberia preserves a complex succession of Mesozoic rifts partly or completely inverted during the Late Cretaceous and Cenozoic in relation with Africa-Eurasia convergence. Notably, the Valencia Trough, classically viewed as part of the Cenozoic West Mediterranean basins, preserves in its southwestern part a thick Mesozoic succession (locally »10km thick) over a highly thinned continental basement (locally only »3,5km thick). This sub-basin referred to as the Columbrets Basin, represents a Late Jurassic-Early Cretaceous hyper-extended rift basin weakly overprinted by subsequent events. Its initial configuration is well preserved allowing us to unravel its 3D architecture and tectono-stratigraphic evolution in the frame of the Mesozoic evolution of eastern Iberia. The Columbrets Basin benefits from an extensive dataset combining high resolution reflection seismic profiles, drill holes, refraction seismic data and Expanding Spread Profiles. Its Mesozoic architecture is controlled by interactions between extensional deformation and halokinesis involving the Upper Triassic salt. The thick uppermost Triassic to Cretaceous succession describes a general synclinal shape, progressively stretched and dismembered towards the basin borders. The SE-border of the basin is characterized by a large extensional detachment fault acting at crustal scale and interacting locally with the Upper Triassic décollement. This extensional structure accommodates the exhumation of the continental basement and part of the crustal thinning. Eventually our results highlight the complex interaction between extreme crustal thinning and occurrence of a pre-rift salt level for the deformation style and tectono-stratigraphic evolution of hyper-extended rift basins.

    The effect of 5-chloro-3-methyl-4-nitro-1H-pyrazole (CMNP) and ethephon on peel color, flavedo carotenoid gene expression, and carotenoid accumulation was investigated in mature 'Valencia' orange ( Citrus sinensis L. Osbeck) fruit flavedo at three maturation stages. Abscission agent application altered peel color. CMNP was more effective than ethephon in promoting green-to-red (a) and blue-to-yellow (b) color at the middle and late maturation stages and total carotenoid changes at all maturation stages. Altered flow of carotenoid precursors during maturation due to abscission agents was suggested by changes in phytoene desaturase (Pds) and ζ-carotene desaturase (Zds) gene expression. However, each abscission agent affected downstream expression differentially. Ethephon application increased β-carotene hydroxilase (β-Chx) transcript accumulation 12-fold as maturation advanced from the early to middle and late stages. CMNP markedly increased β- and ε-lycopene cyclase (Lcy) transcript accumulation 45- and 15-fold, respectively, at midmaturation. Patterns of carotenoid accumulation in flavedo were supported in part by gene expression changes. CMNP caused greater accumulation of total flavedo carotenoids at all maturation stages when compared with ethephon or controls. In general, CMNP treatment increased total red carotenoids more than ethephon or the control but decreased total yellow carotenoids at each maturation stage. In control fruit flavedo, total red carotenoids increased and yellow carotenoids decreased as maturation progressed. Trends in total red carotenoids during maturation were consistent with measured a values. Changes in carotenoid accumulation and expression patterns in flavedo suggest that regulation of carotenoid accumulation is under transcriptional, translational, and post-translational control.

    Full Text Available Se presentan los resultados del estudio interdisciplinar del yacimiento ibérico de la Cueva del Sapo (Chiva, Valencia. Las características del conjunto estudiado muestran un contexto ritual que sería frecuentado entre los SS. V-II a. C. La diversidad cronológica y material así como el volumen de restos indican la existencia de varias actividades rituales intermitentes, no generalizadas y que se suceden en el tiempo. Nos acercamos a ellas a través de la presencia de restos de fauna, con escasas evidencias de consumo que reflejan un ritual principal en torno a la figura del ciervo, huesos humanos sin incinerar con marcas que demuestran un tratamiento concreto del cadáver ligado a un complejo ritual funerario en época ibérica y otros materiales –cerámicas, metales y carbones– que también son pruebas de una actividad ritual en la cueva, cuyas características difieren de los criterios tradicionales establecidos para las cuevas con materiales ibéricos. Todos estos factores nos hacen replantearnos la definición tradicional, todavía vigente, para este tipo de contextos rituales, cargada en algunas ocasiones de excesivas generalizaciones.

    Mora Sanchez, Francisco; Lopez-Baeza, Ernesto

    This work studies and quantifies the forest fire that took place in the province of Valencia, Spain, that particularly affected the municipality of Alcublas. This fire was one of the most intense and catastrophic fires that extended over the Valencian Community. Besides quantifying the area affected by the fire according to a severity index, the analysis was carried out from different viewpoints, namely land use, municipal, and cadastral. The data used were, on the one hand, two images from Landsat 7 Enhanced Thematic Mapper Plus (ETM+) satellite, respectively before and after the fire. On the other hand, we also used CORINE Land Cover 2006 Land Use data, a digital terrain model (DTM), the cadastre or land registration from Alcublas and the Spanish topographic map at scale 1:25000 (MTN25). The method used consisted of different steps: atmospheric correction of the images with the dark-object subtraction technique, topographic correction of the images with a 5 m resolution DTM and the Minnaert method, and the elimination of the Landsat 7 Scan Line Corrector (SLC-off) effect by using the Delaunay triangulation method. Once the images were corrected, we computed the Normalized Burn Ratio (NBR) to highlight and characterise the areas that were burnt by means of a standard severity index. The estimation of the affected area was done through the difference of the images respectively before and after the fire that was also trimmed off to actually obtain the affected area. Once the forest fire was classified, the total affected area was estimated for each severity index and overlaid the Spanish topographic map (1:25000) thus being able to calculate the affected area for each municipality, land use and cadastrial property. The total burnt area was 19910 ha, the most affected municipality -in extension- was Andilla with 4966 ha. But the most significant one was precisely Alcublas with 60,64% of its area burnt. The area burnt for each land use was also estimated according to

    The cell envelope proteins of 89 environmental Vibrio cholerae non O1 strains isolated from lake and coastal waters near Valencia, Spain, and six Vibrio cholerae strains from culture collections were analyzed by sodium dodecyl sulphate-polyacrylamide gel electrophoresis. Considerable heterogeneity was found in the major proteins of the environmental non-O1 strains, but bands between 25,000 and 48,000 daltons were observed in the majority of the strains. Estimated relative mobilities of the total protein profile ranged between 11 and more than 100 Kd. Cluster analysis revealed four groups of strains distinguishable by presence or absence of high and low molecular weight proteins. After treatment with Sarkosyl, the outer membrane proteins (OMPs) were characterized in all strains by densitometric methods. They ranged from 19 to 87 Kilodaltons, and corresponded to the major proteins observed in the total membrane preparations. The major OMP most frequently found had a molecular weight around 37 Kd, similar to that of porins in other Gram-negative bacteria. The OMP composition varied in response to culture medium and growth phase. Generally the OMP expression was affected only in a quantitative way by the growth phase while the growth medium had both a qualitative and a quantitative effect.

    Our purpose was to determine the prevalence of mutations of resistance to nucleoside inhibitors of reverse transcriptase (NIRT) and protease inhibitors (PI) in the HIV-1 genotype of naïve infected subjects in the prisons of the Autonomous Community of Valencia, Spain. Multicentric, descriptive, cross-sectional study of prevalence including a systematic stratified and randomised sampling by centres. Demographic, clinical, virological and immunological data were collected. The HIV gene of protease and transcriptase was studied in peripheral blood plasma samples by means of double PCR amplification and subsequent automatic sequence. Reference: wild strain HXB2. Plasma was obtained from 133 individuals (119 men and 14 women). 117 samples were selected and the rest did not have enough copies for transcription. With regard to NIRT, 7 samples (5.2% of total) showed some mutation of resistance: M41L, D67N, L210W and K219Q, all them secondary to and associated with resistance to zidovudine, abacavir as well as group B multinucleoside-resistance. With regard to PI, only one sample showed a primary mutation, M46I, which was associated with resistance to indinavir. Moreover, a further 41 samples were found to express some secondary mutation. In our series, there was a low number of primary mutations of resistance. These results allow us to exclude the systematic use of resistance tests before an initiation antiretroviral therapy.

    Full Text Available Fundamento: La enfermedad de Chagas es una patología emergente en nuestro medio debido principalmente al incremento de las migraciones. La prevalencia y el difícil manejo terapéutico hacen del Chagas un problema de salud pública creciente. Pretendemos analizar la prevalencia y perfil epidemiológico de mujeres gestantes latinoamericanas atendidas en el área de influencia del Hospital Clínico de Valencia (HCUV y estimar el riego de transmisión vertical. Métodos: Se estudió a 383 mujeres gestantes asistidas en el HCUV entre febrero de 2005 y julio de 2007. Utilizamos para el cribado la técnica de inmunoprecipitación ID-PaGIA-DiaMed, confirmada mediante Inmunofluorescencia Indirecta (IFI - Inmunoflour Chagas-Inverness Medical. En hijos de mujeres positivas: Microhematocrito, PCR y detección de anticuerpos IgM por IFI, al nacer, e IgG, a los 6 y 12 meses. Resultados: El 9,7% de las mujeres presentaban anticuerpos específicos del parásito. De ellas el 54,1% eran bolivianas, el 13,5% argentinas y 8,1 % colombianas. 81,1% vivieron en zonas rurales y casas de adobe, el 89,2% tenía antecedentes familiares y el 100% conocían la enfermedad y el vector. La seroconversión en un niño de 8 meses supuso una transmisión vertical del 2,7% y una incidencia en mujeres procedentes de zona endémica del 0,3%. Conclusiones: La prevalencia de enfermedad de Chagas en mujeres gestantes latinoamericanas es elevada y supone un riesgo de transmisión vertical importante que obliga a detectar anticuerpos frente al parásito en los exámenes de salud de este colectivo. En el cribado son factores de riesgo los antecedentes familiares de tripanosomiasis y la residencia previa en hábitat rural.

    To describe the health related quality of life in a population sample of postmenopausal women over the age of 50 and resident in the city of Valencia (Spain), according to the presence/absence of osteoporosis and the severity of prevalent morphometric vertebral fractures. A cross-sectional age-stratified population-based sample of 804 postmenopausal women of 50 years of age and older were assessed with the SF-12 questionnaire. Information about demographic features, lifestyle, clinical features, educational level, anti-osteoporotic and other treatments, comorbidities and risk factors for osteoporosis were collected using an interviewer-administered questionnaire and densitometric evaluation of spine and hip and spine x-rays were carried out. In the non-adjusted analysis, mild and moderate-severe vertebral fractures were associated with decreased scores in the SF-12 Physical Component Summary (PCS) but not in the Mental Component Summary (MCS), while densitometric osteoporosis with no accompanying fracture was not associated with a worse health related quality of life. In multivariate analysis worse PCS scores were associated to the age groups over 70 (-2.43 for 70-74 group and -2.97 for 75 and older), chronic conditions (-4.66, -6.79 and -11.8 according to the presence of 1, 2 or at least 3 conditions), obesity (-5.35), peripheral fracture antecedents (-3.28), hypoestrogenism antecedents (-2.61) and the presence of vertebral fracture (-2.05). After adjusting for confounding factors, the physical components of health related quality of life were significantly lower in women with prevalent osteoporotic vertebral fractures than in women--osteoporotic or not--without vertebral fractures.

    Purpose: The provided output factors for Elekta Nucletron’s skin applicators are based on Monte Carlo simulations. These outputs have not been independently verified, and there is no recognized method for output verification of the vendor’s applicators. The purpose of this work is to validate the outputs provided by the vendor experimentally. Methods: Using a Flexitron Ir-192 HDR unit, three experimental methods were employed to determine dose with the 30 mm diameter Valencia applicator: first a gradient method using extrapolation ionization chamber (Far West Technology, EIC-1) measurements in solid water phantom at 3 mm SCD was used. The dose was derived based on first principles. Secondly a combination of a parallel plate chamber (Exradin A-10) and the EIC-1 was used to determine air kerma at 3 mm SCD. The air kerma was converted to dose to water in line with TG-61 formalism by using a muen ratio and a scatter factor measured with the skin applicators. Similarly a combination of the A-10 parallel plate chamber and gafchromic film (EBT 3) was also used. The Nk factor for the A-10 chamber was obtained through linear interpolation between ADCL supplied Nk factors for Cs-137 and M250. Results: EIC-1 measurements in solid water defined the outputs factor at 3 mm as 0.1343 cGy/U hr. The combination of A-10/ EIC-1 and A-10/EBT3 lead to output factors of 0.1383 and 0.1568 cGy/U hr, respectively. For comparison the output recommended by the vendor is 0.1659 cGy/U hr. Conclusion: All determined dose rates were lower than the vendor supplied values. The observed discrepancy between extrapolation chamber and film methods can be ascribed to extracameral gradient effects that may not be fully accounted for by the former method.

    Citrus Huanglongbing (HLB) is considered the most destructive citrus disease worldwide. Symptoms-based detection of HLB is difficult due to similarities with zinc deficiency. To find metabolic differences between leaves from HLB-infected, zinc-deficient, and healthy 'Valencia' orange trees by using GC-MS based metabolomics. Analysis based on GC-MS methods for untargeted metabolite analysis of citrus leaves was developed and optimized. Sample extracts from healthy, zinc deficient, or HLB-infected sweet orange leaves were submitted to headspace solid phase micro-extraction (SPME) and derivatization treatments prior to GC-MS analysis. Principal components analysis achieved correct classification of all the derivatized liquid extracts. Analysis of variance revealed 6 possible biomarkers for HLB, of which 5 were identified as proline, β-elemene, (-)trans- caryophyllene, and α-humulene. Significant (P < 0.05) differences in oxo-butanedioic acid, arabitol, and neo-inositol were exclusively detected in samples from plants with zinc deficiency. Levels of isocaryophyllen, α-selinene, β-selinene, and fructose were significantly (P < 0.05) different in healthy leaves only. Results suggest the potential of using identified HLB biomarkers for rapid differentiation of HLB from zinc deficiency. Copyright © 2010 John Wiley & Sons, Ltd.

    This study was carried out to determine the current levels of nitrates in vegetables and vegetable-based baby foods (a total of 1150 samples) marketed in the Region of Valencia, Spain, over the period 2000-2008, and to estimate the toxicological risk associated with their intake. Average (median) levels of nitrate in lettuce, iceberg-type lettuce and spinach (1156, 798 and 1410 mg kg(-1) w/w, respectively) were lower than the maximum limits established by European Union legislation. Thirteen fresh spinach samples exceeded the regulatory limits. Median nitrate values in other vegetables for which a maximum limit has not been fixed by the European Commission were 196, 203, 1597, 96, 4474 and 2572 mg kg(-1) w/w (for potato, carrot, chard, artichoke, rucola and lamb's lettuce, respectively). The estimated nitrate daily intakes through vegetables consumption for adult, extreme consumers and children were found to be about 29%, 79.8% and 15.1%, respectively, of the acceptable daily intake (3.7 mg kg(-1)). The levels (median = 60.4 mg kg(-1) w/w) found in vegetable-based baby foods were, in all cases, lower the maximum level proposed by European Union legislation. The estimated nitrate daily intake through baby foods for infants between 0-1 and 1-2 years of age were 13% and 18%, respectively, of the acceptable daily intake.

La obtención de los transgénicos responde a intereses comerciales y mercantilistas y no a una respuesta para el campesino ni para el medio ambiente ni para el consumidor. Al consumidor se le está negando una información vital cuando no se le suministra información visible y medianamente comprobable para que tenga la posibilidad de elegir cómo alimentarse. Los organismos modificados genéticamente (OMG pueden representar peligros muy grandes para el planeta. Actualmente, los cultivos transgénicos han incrementado las áreas productivas en forma exponencial, y están prácticamente en todo el orbe. Y aunque las áreas de agricultura orgánica, limpia, y sostenible han aumentado enormemente con resultados positivos demostrados contundentemente, la proporción con respecto a los transgénicos coloca a la humanidad en serios riesgos. Para los recursos naturales no es menos crítica la situación, ya que se han podido demostrar categóricamente las consecuencias negativas con estudios serios y de varios años.

Close to 2000 Erasmus students attend yearly the lectures in Valencia University. Most of them arrive to Valencia -also to Granada, Barcelona and Salamanca- because the cultural attractive. Valencia moreover offers a warm and dry climate, which make the University of Valencia very popular for the Erasmus students. In 2003 a survey developed by the International Exchange Coordinator of the Geography Degree shown that 33 % of the student choose the Valencia University because the night-life, 22 % because the climate, 23 % because the suggestion of a friend (mainly due to the climate and night-life) and only 22 % because of the academic background of the university. Another survey at the end of the 2003-2004 year shown that 84 % of the Erasmus student did not know that Valencia had a lagoon (called l'Albufera) nearby, and that 23 % of the students ignored that the main park of the city was developed on the river bed, after the artificial change of the mouth of the river to a southern position due to the flood of 1957. The Erasmus students new almost nothing about the landscape of the surroundings and the city of Valencia. A strategy was developed since 2003 by the International Exchange Coordinator of the Geography Degree to show to the students coming from the Erasmus project the landscape of the Valencia Country by means of field visits to the key locations in two days. One day is devoted to the coastal land where lagoons, river mouths and population concentration are the main topics. The second day a trekking on the mountains located at the Sierra de Enguera give an idea to the students of the Desertification processes after the land abandonment during the 50 and 60's. The students attending the lectures and the two days excursion (280 in 2008) found this excursion as a key point in their adaptation to the new university as they know how is the

    Infiltration is a key process of the hydrological cycle. Infiltration also controls the soil water resources, and the development of the vegetation, and moreover, in the Mediterranean, determines the runoff generation (Cerdà, 1996; 1997; 2001). In the Mediterranean, the infiltration in forest soils shows high spatial variability and seasonal and temporal changes (Cerdà, 1999; Bodí and Cerdà, 2009) and is being affected by forest fires (Cerdà, 1998), which introduce a new temporal change in the seasonality of the infiltration rates. Although the forest soils are well assessed, there is no information about the infiltration in urban areas in Mediterranean cities. The Mediterranean dense urban systems use to be treated as impermeable areas. However, the cities show areas covered by vegetation and with soils that allow the rainfall to infiltrate. Those areas are mainly the parks. In order to shed some light on the infiltration capacity of the soils of the urban area of Valencia city 30 rainfall simulations experiments (Cerdà, 1996) and 90 ring infiltrometer (10 cm diameter) measurements were carried out in January 2011, and they were repeated in July 2011, to compare wet (19.4 % of soil moisture) and dry (5.98 % of soil moisture) soils. The infiltration curves where fitted to the Horton (1933) equation and they lasted for 1 hour. The results show that the infiltration is 11 times higher when measured with ring infiltrometer than with the simulated rainfall at 55 mmh-1, and that the infiltration rates where higher in summer than in winter: 2.01 higher for the ring infiltrometer, and 1.45 higher when measured with the rainfall simulator. In comparison to the soils from the forest areas, the infiltration rate in the gardens were lower, with values of 10.23 and 21.65 mm h-1 in average for winter and summer when measured with the rainfall simulator. Similar results were found with the ring infiltrometer. It was also found a clear relationship between the vegetation

    Full Text Available The Valencia orange orchards established on soils of low fertility in the Northwest region of Paraná State, Brazil, have showed symptoms of Mg deficiency and reduced fruit yields. The objective of this study was to verify the relationship between yield with soil and leaf nutrients during 1996/97 growing season. Two sites of low and high productivity were selected in seven orchards. Leaf and soil samples (fertilized rows and interrows were collected in 1996. The results showed that the citrus yields were negatively related with soil Mg/K and Ca+Mg/K ratios in the fertilized rows, and fruit weight positively correlated with leaf Zn in the low productivity orchards. The fruit weight was positively related with leaf Ca and soil Ca in the fertilized rows of the high productivity orchards. The results suggested an adequate lime and K fertilization managements in the fertilized rows, as well as an adequate Zn supply.Os pomares de laranja Valência (Citrus sinensis (L.

    Full Text Available Abstract Background Family function may have an influence on the mental health deterioration of the caregivers of dependent family members and it could have a varying importance on the care of dependents. Little attention has been paid to the preparation of minor stroke survivors for the recovery trajectory or the spouse for the caregiving role. Therefore, this study protocol intends to analyze the influence of family function on the protection of patients with stroke sequels needing physiotherapy in the family environment. Methods/Design This is an analytical observational design, prospective cohort study and using a qualitative methodology by means of data collected in the “interviews of life”. The study will be carried out by the Rehabilitation Service at Hospital of Elda in the Valencia Community. All patients that have been diagnosed with stroke and need physiotherapy treatment, having a dependency grade assigned and consent to participate in the study, will undergo a monitoring of one year in order to assess the predictive factors depending on the dependence of the people affected. Discussion Our research aims to analyze the perception of caregivers, their difficulties to work, and the influence of family function. Moreover, it aims to register the perception of the patients with stroke sequel over the care received and whether they feel protected in their family environment.

    The most destructive wildfire experienced in Spain since 2004 occurred close to Valencia in summer 2012. A total of 48.500ha were affected by two wildfires, which were mostly active during 29-30 June. The fresh smoke plume was detected at the Burjassot measurement station simultaneously to a severe dust episode. We propose an empirical method to evaluate the dust and smoke mixing and its impact on the microphysical and optical properties. For this, we combine direct-sun measurements with a Cimel CE-318 sun-photometer with an inversion methodology, and the Mie theory to derive the column-integrated size distribution, single scattering albedo (SSA) and asymmetry parameter (g). The mixing of dust and smoke greatly increased the aerosol load and modified the background aerosol properties. Mineral dust increased the aerosol optical depth (AOD) up to 1, while the smoke plume caused an extreme AOD peak of 8. The size distribution of the mixture was bimodal, with a fine and coarse modes dominated by the smoke particles and mineral dust, respectively. The SSA and g for the dust-smoke mixture show a marked sensitivity on the smoke mixing-ratio, mainly at longer wavelengths. Mineral dust and smoke share a similar SSA at 440nm (~0.90), but with opposite spectral dependency. A small dust contribution to the total AOD substantially affects the SSA of the mixture, and also SSA at 1020nm increases from 0.87 to 0.95. This leads to a different spectral behaviour of SSA that changes from positive (smoke plume) to negative (dust), depending on the dust and smoke mixing-ratio. Copyright © 2017 Elsevier B.V.

    Occurrence of antibiotic-resistant pathogenic or commensal enterobacteria in marketed agricultural foodstuffs may contribute to their incorporation into the food chain and constitutes an additional food safety concern. In this work, we have determined the clinically relevant resistances to 11 common chemotherapeutic agents in Enterobacter and Klebsiella isolates from fresh vegetables from various sources (supermarkets and greengrocers' shops in Valencia, Spain). A total of 96 isolates were obtained from 160 vegetables analyzed (50% positive samples): 68 Enterobacter isolates (59 E. cloacae, two E. aerogenes, two E. cancerogenus, one E. gergoviae, and four E. sakazakii, currently Cronobacter spp.), and 28 Klebsiella isolates (19 K. oxytoca and 9 K. pneumoniae). Only seven isolates were susceptible to all agents tested, and no resistances to ceftazidime, ciprofloxacin, gentamicin, and chloramphenicol were detected. Most isolates were resistant to amoxicillin/clavulanic acid (74 [58 Enterobacter and 16 Klebsiella]) or to ampicillin (80 [55/25]). Other resistances were less frequent: nitrofurantoin (13 isolates [12/1]), tetracycline (6 [5/1]), co-trimoxazole (3 [3/0]), cefotaxime (1 [1/0]), and streptomycin (2 [1/1]). Multiresistant isolates to two (56 [41/15]), three (10 E. cloacae isolates), four (one E. cloacae and one K. pneumoniae isolate), and five (two E. cloacae isolates) chemotherapeutic agents were also detected. The presence of potential pathogens points to marketed fresh produce, which often is eaten raw, as a risk factor for consumer health. In addition, these results support the usefulness of these bacterial species as indicators of the spreading of antibiotic resistances into the environment, particularly in the food chain, and suggest their role as carriers of resistance determinants from farms to consumers, which may constitute an additional "silent" food safety concern. Therefore, there is a need to improve the hygienic quality of marketed fresh

    Numerous studies have focused on the effects of exposure to air pollution on health; however, certain subsets of the population tend to be more exposed to such pollutants depending on their social or demographic characteristics. In addition, exposure to toxicants during pregnancy may play a deleterious role in fetal development as fetuses are especially vulnerable to external insults. The present study was carried out within the framework of the INMA (Infancia y Medio Ambiente or Childhood and the Environment) multicenter cohort study with the objective of identifying the social, demographic, and life-style factors associated with nitrogen dioxide (NO(2)) exposure in the subjects in the cohort. The study comprised 785 pregnant women who formed part of the INMA cohort in Valencia, Spain. Outdoor levels of NO(2) were measured at 93 sampling sites spread over the study area during four different sampling periods lasting 7 days each. Multiple regression models were used for mapping outdoor NO(2) throughout the area. Individual exposure was assigned as: 1) the estimated outdoor NO(2) levels at home, and 2) the average of estimated outdoor NO(2) levels at home and work, weighted according to the time spent in each environment. The subjects' socio-demographic and life-style information was obtained through a questionnaire. In the multiple linear analyses, the outdoor NO(2) levels assigned to each home were taken to be the dependent variable. Other variables included in the model were: age, country of origin, smoking during pregnancy, parity, season of the year, and social class. These same variables remained in the model when the dependent variable was changed to the NO(2) levels adjusted for the subjects' time-activity patterns. We found that younger women, those coming from Latin American countries, and those belonging to the lower social strata were exposed to higher NO(2) levels, both as measured outside their homes as well as when time-activity patterns were taken

La cavidad contiene un relleno sedimentario formado por diecisiete niveles estratigráficos que abarcan desde el OIS 9 al OIS 5e. Esta amplia secuencia cronológica permite abordar diferentes cuestiones relacionadas con los grupos humanos de este periodo y sus relaciones con el medio ambiente. Concretamente, a partir del estudio zooarqueológico del nivel XII (OIS 6, se ha reconstruido la secuencia antrópica de obtención y procesamiento de los recursos faunísticos. De este modo, se han identificado diferentes estrategias de subsistencia llevadas a cabo por los homínidos para la obtención de los animales. Estas técnicas van desde el carroñeo hasta la caza e incluyen el aprovisionamiento de pequeñas presas como las aves (Cygnus olor o los lepóridos (Oryctolagus cuniculus. Esta variabilidad de estrategias podría interpretarse como la gran capacidad de adaptación que poseen estos grupos humanos para aprovechar las oportunidades que el medio les ofrece. También se ha observado la existencia de patrones bien sistematizados tanto en el aprovechamiento de los recursos faunísticos externos (piel, carne, tendones como en la obtención de los recursos internos (médula. Muchos de los elementos diagnósticos que evidencian la fracturación antrópica en el nivel XII presentan cierta sistematización en zonas y partes anatómicas concretas.

    In recent years, studies into the presence and distribution of emerging contaminants (ECs), like pharmaceutical products, some pesticides and mycotoxins in the natural environment, are receiving considerable attention. Thus, the presence of these compounds in waters, soils and wastes in different locations including agricultural systems has been stressed; very few studies into this matter are available in Spain. The main source of ECs in the environment is wastewater spillage from wastewater treatment plants (WTP), where these compounds arrive from the sewer system network. The objective of this study was to determine the levels of 35 ECs constituted by nine pharmaceutical products, 23 fungicides and three mycotoxins in soils, sewages sludge and waters adjacent to WTP from an agriculture area of Valencia (E Spain) influenced by intense urban and industrial activity. Seven samples from sludge, 13 soil samples and eight samples of waters from the area of influence of WTP were collected. The ECs extraction were performed using 5 g of fresh sample and a mixture of acetonitrile with 1% formic acid and water at the 3:1 ratio by shaking for 45 min and then centrifuging at 4,000 rpm for 5 min. The extract was filtered and determination was done by HPLC system connected to a 3200-Qtrap de triple quadrupole mass spectrometer with an electrospray ion source. The results showed that soil-ECs concentrations were 10 times lower that in sewage sludge. The smaller number of detections and detected compounds should also be stressed. As in previous cases, fungicides azole (tebuconazole and tricyclazole), along with boscalid, were the most detected compounds with concentrations of between 100 and 400 µg kg-1 dw. In second place, propiconazole and azoxystrobin stood out, followed by carbendazim, dimetomorph, pyraclostrobin and propamocarb. The following drugs and mycotoxins were detected to have a higher to lower concentration (1-40 µg kg-1): telmisartan, irbesartan, venlafaxine

    Helicobacter pylori infection (Hp) is widely spread around the world, and it is considered one of the main causes of chronic gastritis, peptic and duodenal ulcers, and gastric cancer. Recent research has shown that it can be associated with nutritional disorders, mainly with iron and other micronutrient deficiencies. The objective of this study was to assess the prevalence of Hp infection, and infection pattern according to age, sex, nutritional status, and socioeconomic conditions in children who attended the Unidad Educativa "Valentin Espinal" in the city of Valencia. 170 children, between 3 and 14 years of age were studied to assess Hpylori infection (13C-urea breath test), age, nutritional status according to BMI and Height for age, hemoglobin (cianometahemoglobin), serum ferritin (ELISA), socioeconomic status (Graffar-Méndez-Castellano), housing conditions, number of families and of people cohabitating in the same household, and quality of services. 78.8% of the children were infected with Hp, witch was significantly correlated with age but not gender. 25.9% of the sample had undernutrition, and 46.5% were stunted. 98.1% of the families lived in poverty, and 98% of the households showed sanitary deficiencies. A mean of 6.0 +/- 2.4 persons lived in each household (range: 2-15), and an average of 3.2 person shared bedrooms. The odds of being infected were higher in those children who were stunted. Also, socioeconomic status, mother's education level, and poor hosing conditions were significantly associated to being infected. Hpylori is highly prevalent among socially and economically deprived children, and age, overcrowding, and a low education level of the mother increases the risk of being infected.

    Ground penetrating radar is usually employed for non-destructive detection of cavities in karst areas and road maintenance. This paper describes the inspection for cavity detection in a street located in Torrente (Valencia, Spain) where a new sewerage project was planned. Torrente population growth (more than 80,000 inhabitants last year) has caused urban development southwards from its downtown. According to municipality geologic configuration, new urbanized areas are located in mountains composed of limestone with presence of karst systems. During excavation work for a sewerage system installation, a 4 x 2 x 1.5 m shallow cave was found in one planned street. For this reason, digging activities were stopped and a GPR survey was carried out on the street. A 1x1 m grid was collected using a GSSI SIR-3000 equipment. A 400 MHz frequency antenna was used for reaching 2.5 m approx. depth, attending the characteristics of the discovered cave and the excavation project depth. GPR records were calibrated in situ, thanks to the unearthed cavity. The 3D GPR-data interpretation mapped several caves only on one side of the street. The detected cavities coincided with the sewerage system layout. These underground spaces were isolated from each other, as small individual karst caves. The outcomes of this study allowed the modification of the sewerage project. Therefore, the sewerage system layout was moved to the other side of the street where no cavities were detected with the GPR survey. GPR is proved to be an efficient tool to be taken into consideration by civil engineers and architects for designing new infrastructures (e.g. sewerage systems) in urban planning areas. We conclude GPR helps minimising cost, time and inconveniences to neighbourhood during excavation works, especially in cities.

    This study evaluated the efficacy of an intervention combining the Valencia model of waking hypnosis with cognitive-behavioral therapy (VMWH-CBT) in managing cancer-related pain, fatigue, and sleep problems in individuals with active cancer or who were post-treatment survivors. We hypothesized that four sessions of VMWH-CBT would result in greater improvement in participants' symptoms than four sessions of an education control intervention. Additionally, we examined the effects on several secondary outcome domains that are associated with increases in these symptoms (depression, pain interference, pain catastrophizing, and cancer treatment distress). The study design was a randomized controlled crossover clinical trial comparing the VMWH-CBT intervention with education control. Participants (N = 44) received four sessions of both treatments, in a counterbalanced order (n = 22 per order condition). Participants were 89% female (N = 39) with mean age of 61 years (SD = 12.2). They reported significantly greater improvement after receiving the active treatment relative to the control condition in all the outcome measures. Treatment gains were maintained at 3-month follow-up. This study supports the beneficial effects of the VMWH-CBT intervention relative to a control condition and that treatment gains remain stable. VMWH-CBT-trained clinicians should be accessible for managing symptoms both during and after cancer treatment, though the findings need to be replicated in larger samples of cancer survivors.

    Full Text Available Las hormigas forrajeras (Atta spp. pueden destruir plantaciones completas de hortalizas y de otras plantas de importancia económica en América Tropical y Subtropical. Cortan el tejido de las plantas y lo transportan a nidos subterráneos, donde cultivan un hongo del Phylum basidiomycota, que es su alimento principal. En la actualidad, no se cuenta con una estrategia efectiva de manejo de esta plaga. La mayoría de productos disponibles comercialmente son muy poco efectivos, dejan residuos en el ambiente y tienen un precio alto para los pequeños agricultores. La presente investigación se propuso evaluar diferentes ingredientes en la preparación de granulados que presenten alto nivel de acarreo y potencial para la incorporación de ingredientes activos con efecto biológico contra el hongo simbiótico que cultivan las hormigas forrajeras. Se prepararon gránulos con diferentes combinaciones y concentraciones de excipientes o coadyuvantes. Además se evaluó citropulpa, extracto alcohólico de cáscaras de naranja y aceite de semillas de naranja, como atrayentes. A los mejores formulados se incorporó extracto de Azadirachta indica (neem, 3 cepas de Trichoderma spp., y levaduras en diferentes concentraciones, para comprobar la compatibilidad de las formulaciones con ingredientes activos. Se evaluó diferentes características de los gránulos como indicadores de viabilidad y estabilidad del formulado. Se encontró que los cebos formulados con citropulpa son capaces de mantener estable la acidez y, además, conservan la viabilidad de Trichoderma spp., y levaduras por más tiempo que los formulados elaborados con extracto alcohólico de cáscaras de naranja como atrayente. Además, el gránulo base con citropulpa presentó un costo de producción más bajo. Se concluye que el formulado con citropulpa como atrayente es una base apropiada para la incorporación de ingredientes activos con efecto biológico contra el hongo simbiótico y tiene

    Introduction and objectives: Several registries of acute myocardial infarction (AMI) have been carried out in Spain, but few remain active. This work analyses the evolution of the characteristics and control of patients with AMI during the first 10 years of the PRIMVAC registry, initiated in 1995. Methods: The demographical and clinical characteristics, therapeutic-diagnostic procedures and pharmacological treatment of patients admitted with AMI between January 1995 and December 2004, were analysed in 17 coronary centres in the Autonomous Community of Valencia (South eastern Spain). Results: The mean age of the 19,719 patients recruited was of 65. The percentage of women, hypertension, hypercholestrolemia and diabetes increased during registry period. The median time of symptoms onset-hospital arrival was 151 minutes, without a decrease over the time, and the delay of thrombolysis fell from 200 to 154 minutes (p<0.01). Percentage of thrombolytic treatment oscillated between 39% and 48%. The mortality in the coronary units decreased (14.1% vs. 8.9%; p<0.001). The number of coronary angiography and percutaneous revascularisation performed increased up to 61% and 32%, respectively, of patients included. On discharge, the use of beta-blockers (29.3% vs. 66.7%), angiotensin-converting enzyme (ACE) inhibitors (41.7% vs. 57.9%) and statins (29.3% vs. 71%) went up. Conclusions: Overall mortality in the coronary unit decreased, without any variation in the incidence of serious complications. Time to thrombolysis was reduced over the time, with no significant increment in its use. The performance of coronary angiography and percutaneous revascularisation increased, with a low use of primary angioplasty. The use of beta-blockers, ACE inhibitors and statins increased at discharge. PMID:23675181

    A wide range of emerging pollutants have been identified in environment: antibiotics, hormones, personal care products, etc. But quite recently a new class of ecological threat has been reported: the presence in waters of abuse drugs coming from human consumption [1,2]. Treatment of wastewaters may remove a portion of these compounds, but sometimes, these treatments are insufficient or nonexistent, residues can reach into the aquatic environment. ĹAlbufera Natural Park (Valencia, Spain) is a marsh area of a great interest because it is the habitat of a large quantity of unique species of flora and fauna, and a zone of refuge, feeding and breeding for a large number of migratory birds. However, this area is threatened by urban, industrial and agricultural pressures. The aim of this work has been to develop a fast and sensitive multi-residue analytical method for to establish the occurrence and distribution of commonly consumed illicit drugs in surface waters of ĹAlbufera lake. A representative set of abuse drugs with different mode of action was chosen for this purpose, including: amphetaminics, opiates, cocainics and cannabinoids (THC and nor-9-carboxy-THC). In April 2008 and October 2008 a total of 16 samples of water were collected, corresponding to different sampling points previously designed, and covering the most important channels that flow in to the lake. Samples of 250 mL of water were concentrated by Solid Phase Extraction through an Oasis HLB cartridge and extracted subsequently with methanol as solvent. Quantification was carried out by LC-MS/MS with an ESI interface. Performance characteristics of the PLE-SPE followed by LC-MS/MS were established by validation procedure. Selectivity, linearity, precision, recoveries and limits of detection (LOD) and quantification (LOQ) were studied. Our search shows that current sewage treatment systems do not completely remove illicit drug residues from urban wastewater. Benzoylecgonine, the main metabolite from

    Irrigation systems are considered as one of the major landscapes features in western Mediterranean environments. Both socio-economic and cultural elements are interrelated in their development and preservation. Generally, due to their location in flat lands and close to major urban-industrial zones, irrigation lands are suffering of intense pressures that can alter their agricultural values, environmental quality and, consequently, the sustainability of the systems. To understand the nature of anthropogenic pressures on large Mediterranean water agricultural systems a methodology based on environmental forensics criteria has been developed and applied to La Albufera Natural Park in Valencia (Eastern Spain), a protected area where traditional irrigation systems exists since Muslim times (from 8th to 15th centuries). The study analysed impacts on water and soils, for the first case the fate of emerging contaminants of urban origin (pharmaceuticals and illegal drugs) are analysed. Impact on soils is analysed using the dynamics urban expansion and the loss and fragmentation of soils. The study focused is organised around two major procedures: (1) analysis of 16 water samples to identify the presence of 14 illicit drugs and 17 pharmaceutical compounds by Liquid Chromatography-Mass Spectrometry techniques; (2) spatial analysis with Geographical Information Systems (GIS) integrating different sources and data formats such as water analysis, social, location of sewage water treatment plan and the synchronic comparison of two soil sealing layers -for the years 1991 and 2010. Results show that there is a clear trend in the introduction of pharmaceutical in the irrigation water through previous use of urban consumption and, in many cases, for receiving the effluents of wastewaters treatment plants. Impacts on soils are also important incidence in the fragmentation and disappearance of agricultural land due to soil sealing, even within the protected area of the Natural Park

Increased extracellular pH and internalization into living yeast cells triggered molecular gate aperture and cargo release. Proper performance of the system was demonstrated with nanodevices loaded with fluorescein or with the antifungal agent tebuconazole. Interestingly, nanodevices loaded with tebuconazole significantly enhanced tebuconazole cytotoxicity. As alterations of acidic external pH are a key parameter in the onset of fungal vaginitis, this nanodevice could improve the treatment for vaginal mycoses.Keywords: capped mesoporous nanoparticles, intracellular release, pH-responsive nanoparticles, Saccharomyces cerevisiae, tebuconazole loading

    Full Text Available Objetivos. Estudiar la intensidad de la exposición al monóxido de carbono (CO, los factores contribuyentes a esta exposición y sus potenciales efectos sobre la salud en vendedores de quioscos ubicados en una avenida de alta densidad de tránsito en Valencia, Venezuela. Métodos. Se midió la concentración de CO en el aire (CO-aire en 16 quioscos y se determinó la concentración sanguínea de carboxihemoglobina (COHb-S en los individuos que trabajaban en esos quioscos y en un grupo de control formado por docentes, estudiantes y obreros de la Universidad Simón Rodríguez, ubicada en una zona montañosa, apartada, sin contaminación ambiental aparente. Resultados. En el grupo expuesto no se encontró correlación entre las concentraciones de COHb-S y de CO-aire. La COHb-S media del grupo expuesto (2,9% fue significativamente superior a la del grupo de control (1,6% y a la concentración permisible según el método analítico empleado (< 1,5%. Todos los síntomas de frecuencia diaria afectaron a un mayor porcentaje de individuos del grupo expuesto que del grupo de control; entre los de frecuencia diaria, los más comunes en el grupo expuesto fueron la cefalea y la fatiga. En siete quioscos (43,7% se excedieron los límites permisibles de CO-aire. Conclusiones. Aunque la COHb-S media no parece alarmante, las exposiciones al CO registradas podrían tener un impacto adverso sobre la salud de estos trabajadores, especialmente si padecieran una alteración cardiovascular o por el resultado de la acción potenciadora con otros contaminantes ambientales. Se recomienda la realización de nuevos estudios con mediciones más frecuentes y prolongadas, para ejercer medidas de prevención y control de efectos adversos para la salud y estimar la calidad del aire.

    Flash floods are recurrent events around the Mediterranean region. Extreme episodes activate hydro-geomorphic high-intensity processes with low frequency. In urban environments, the complexity becomes higher due to the existence of very quick-response runoff. However, immediate recovery works remove the urban marks. After a short time both the significance and magnitude of the hydro-geomorphic event become completely unrecognizable. Nevertheless, these episodes generate extensive documentation which is testimony of the processes in almost real time. It is necessary to exploit this source typology in order to draw flood sketches when events far in time may lack a sufficiently rich database. This is particularly the case for the Valencia flash flood (October 1957), located in the lower Turia River basin (Eastern Spain). It left numerous pieces of hydro-geomorphic evidence, but its tracks were covered a short while after the flood. In any case, it remains part of a non-systematic legacy that has not yet been exploited, consisting of immediate aerial and oblique high resolution photography, pictures at street level, water marks and administrative records. Paradoxically, despite being considered a milestone in metropolitan territorial planning (the river was definitely diverted), an accurate reconstruction of the hydraulic behaviour was required from an integrated point of view. To this aim, the development of a GIS-Based Model enabled the utilisation of the above-mentioned materials. This non-conventional information was treated jointly from a new perspective. It provided database support through a vast amount of organised, structured and georeferenced information about the 1957 event. In a second stage, the GBM made it possible to characterise the Turia urban reach and interpret both the hydro-geomorphic (trenches along barrier beaches, erosion, deposition, etc.) and hydraulic (urban streams along the streets, flow directions, flood extent, levees breaks, overflows

    There is a risk for an avian influenza AH5N1 virus pandemia. To estimate the magnitude and impact of an AH5N1 pandemic in areas of Latin-America in order to design interventions and to reduce morbidity-mortality. The InfluSim program was used to simulate a highly pathogenic AH5N1 aviar virus epidemic outbreak with human to human transmission in Valencia, Venezuela. We estimated the day of maximal number of cases, number of moderately and severely ill patients, exposed individuals, deaths and associated costs for 5 different interventions: absence of any intervention; implementation of antiviral treatment; reduction of 20% in population general contacts; closure of 20% of educational institutions; and reduction of 50% in massive public gatherings. Simulation parameters used were: population: 829.856 persons, infection risk 6-47%, contagiousness Index Rh o 2,5; relative contagiousness 90%, overall lethality 64,1% and, costs according to the official basic budget. For an outbreak lasting 200 days direct and indirect deaths by intervention strategies would be: 29,907; 29,900; 9,701; 29,295 and 14,752. Costs would follow a similar trend. Reduction of 20% in general population contacts results in a significant reduction of up to 68% of cases. The outbreak would collapse the health care system. Antiviral treatment would not be efficient during the outbreak. Interpersonal contact reduction proved to be the best sanitary measure to control an AH5N1 theoretical epidemic outbreak.

Siguiendo a de Roover, la mera existencia de los libros manual y mayor no es suficiente para afirmar su pertenencia a la partida doble, por lo que fue necesario revisar todos los elementos característicos de este método y compararlos con los que se encontraban en estos libros. También, se fijó como objetivo conocer los motivos que determinaron el modo de registro empleado, pretendiendo conocer la naturaleza de la información que este sistema aportaba y por qué no se respetaron algunas reglas de la partida doble. El sistema contable aprovechó las ventajas del método contable introduciendo varias innovaciones como: los asientos de ajuste sólo en el libro mayor, un doble asiento de apertura y la incorporación, previa a la apertura, del detalle de todas las transacciones que, consecuencia de los ajustes en los libros anteriores, conducían al saldo de apertura. El estudio permite inferir la concepción económica que el cabildo tenía de su organización y el rol que el sistema contable jugó dentro de la organización dado que la información era de carácter interno y confidencial.

    Linked to the enforcement of the European Water Framework Directive (2000) (WFD), which establishes that all countries of the European Union have to avoid deterioration, improve and retrieve the status of the water bodies, and maintain their good ecological status, several remote sensing studies have been carried out to monitor and understand the water quality variables trend. Lake Albufera de Valencia (Spain) is a hypereutrophic system that can present chrorophyll a concentrations over 200 mg·m-3 and transparency (Secchi disk) values below 20 cm, needing to retrieve and improve its water quality. The principal aim of our work was to develop algorithms to estimate water quality parameters such as chlorophyll a concentration and water transparency, which are informative of the eutrophication and ecological status, using remote sensing data. Remote sensing data from Terra/MODIS, Landsat 5-TM and Landsat 7-ETM+ images were used to carry out this study. Landsat images are useful to analyze the spatial variability of the water quality variables, as well as to monitor small to medium size water bodies due to its 30-m spatial resolution. But, the poor temporal resolution of Landsat, with a 16-day revisit time, is an issue. In this work we tried to solve this data gap by applying fusion techniques between Landsat and MODIS images. Although the lower spatial resolution of MODIS is 250/500-m, one image per day is available. Thus, synthetic Landsat images were created using data fusion for no data acquisition dates. Good correlation values were obtained when comparing original and synthetic Landsat images. Genetic programming was used to develop models for predicting water quality. Using the reflectance bands of the synthetic Landsat images as inputs to the model, values of R2 = 0.94 and RMSE = 8 mg·m-3 were obtained when comparing modeled and observed values of chlorophyll a, and values of R2= 0.91 and RMSE = 4 cm for the transparency (Secchi disk). Finally, concentration

    Alcohol consumption has been increasing in the last years and it has become a sociological problem due its derived health and safety problems. Ethyl sulfate is a secondary metabolite of the alcohol degradation that is excreted through the urine (0.010–0.016%) after alcohol ingestion and it is quite stable in water. In this study, a new methodology to determine ethyl sulfate by ion-pair liquid chromatography-tandem mass spectrometry (LC–MS/MS) was developed. Different ion-pairs and additives were tested directly in the sample extracts or in the mobile phase. The best ion-pair was set up adding 0.5 M of tributylamine and 0.1% of formic acid to the sample. The limit of quantification was 0.3 μg L{sup −1} and the intra-day and inter-day precision of the method were ≤ 2.8 and ≤ 3.0%, respectively. Good linearity (r{sup 2} < 0.999) and low matrix effect (< 30% corrected by using internal isotopically labelled internal standard) were achieved. The sampling campaign was from 4th to 20th March of 2014 covering the festivity of Fallas (15th to 19th March).

    Alcohol consumption has been increasing in the last years and it has become a sociological problem due its derived health and safety problems. Ethyl sulfate is a secondary metabolite of the alcohol degradation that is excreted through the urine (0.010–0.016%) after alcohol ingestion and it is quite stable in water. In this study, a new methodology to determine ethyl sulfate by ion-pair liquid chromatography-tandem mass spectrometry (LC–MS/MS) was developed. Different ion-pairs and additives were tested directly in the sample extracts or in the mobile phase. The best ion-pair was set up adding 0.5 M of tributylamine and 0.1% of formic acid to the sample. The limit of quantification was 0.3 μg L"−"1 and the intra-day and inter-day precision of the method were ≤ 2.8 and ≤ 3.0%, respectively. Good linearity (r"2 < 0.999) and low matrix effect (< 30% corrected by using internal isotopically labelled internal standard) were achieved. The sampling campaign was from 4th to 20th March of 2014 covering the festivity of Fallas (15th to 19th March). Ethyl sulfate was determined in all influents of the 3 wastewater treatment plants (Pinedo I, Pinedo II and Quart-Benàger) belonging to Valencia and surrounding area. Ethyl sulfate concentrations ranged from 1.46 to 19.85 μg L"−"1 and alcohol consumption ranged from 1.07 to 56.11 mL day"−"1 inhab"−"1, being the highest value of alcohol consumption determined during Fallas.

    Full Text Available In the framework of Soil Moisture and Ocean Salinity (SMOS Calibration/Validation (Cal/Val activities, this study addresses the use of the PERSIANN-CCS1database in hydrological applications to accurately simulate a whole SMOS pixel by representing the spatial and temporal heterogeneity of the soil moisture fields over a wide area (50×50 km2. The study focuses on the Valencia Anchor Station (VAS experimental site, in Spain, which is one of the main SMOS Cal/Val sites in Europe.

    A faithful representation of the soil moisture distribution at SMOS pixel scale (50×50 km2 requires an accurate estimation of the amount and temporal/spatial distribution of precipitation. To quantify the gain of using the comprehensive PERSIANN database instead of sparsely distributed rain gauge measurements, comparisons between in situ observations and satellite rainfall data are done both at point and areal scale. An overestimation of the satellite rainfall amounts is observed in most of the cases (about 66% but the precipitation occurrences are in general retrieved (about 67%.

    To simulate the high variability in space and time of surface soil moisture, a Soil Vegetation Atmosphere Transfer (SVAT model – ISBA (Interactions between Soil Biosphere Atmosphere is used. The interest of using satellite rainfall estimates as well as the influence that the precipitation events can induce on the modelling of the water content in the soil is depicted by a comparison between different soil moisture data. Point-like and spatialized simulated data using rain gauge observations or PERSIANN – CCS database as well as ground measurements are used. It is shown that a good adequacy is reached in most part of the year, the precipitation differences having less impact upon the simulated soil moisture. The behaviour of simulated surface soil moisture at SMOS scale is verified by the use of remote sensing data from the Advanced

    Although many studies have been conducted on the development and reproductive potential of Diaphorina citri Kuwayama, 1908 (Hemiptera: Liviidae) in different host species, few have evaluated these parameters on different varieties of the same host species. This study evaluated the influence of five commercial varieties of citrus (Citrus spp. L.)--Hamlin, Natal, Pêra, Ponkan, and Valencia-and orange jasmine [Murraya exotica (L.) Jack] on the development of D. citri. Survival rates for the egg stage were highest on orange jasmine (85.7%) and on Valencia (83.3%). The lowest viability of the nymphal stage was also observed on Hamlin, averaging 57.4%. Values for total viability ranged from 65.9 to 32.6%, and were highest on Valencia. The longest egg-adult development time was on Natal, with a mean of 18.4 d; the shortest total development time was on orange jasmine, with a mean of 17.3 d. Based on the fertility life table, the net reproductive rate (Ro) of D. citri was 2.5 times higher when reared on Valencia than on Hamlin. The other parameters (duration of each generation [T], finite rate of increase [lambda], and innate capacity to increase in number [r(m)]) also demonstrated that Valencia is best suited to this insect. The results obtained for the biological parameters and the fertility life table indicate that Valencia and orange jasmine were the most suitable hosts, whereas Hamlin was least suitable for the development of D. citri. These results provide information for the installation of new citrus groves, especially in the choice of varieties to be planted and the location of different varieties within the groves, with a view toward the management of Huanglongbing or HLB.

Then a quantitative structure-retention relationship (QSRR study for the prediction of retention indices (RI of the compounds was developed by application of structural descriptors and the multiple linear regression (MLR method. Principal components analysis was used to select the training set. A simple model with low standard errors and high correlation coefficients was obtained. The results illustrated that linear techniques such as MLR combined with a successful variable selection procedure are capable of generating an efficient QSRR model for prediction of the retention indices of different compounds. This model, with high statistical significance (R2 train = 0.983, R2 test = 0.970, Q2 LOO = 0.962, Q2 LGO = 0.936, REP(% = 3.00, could be used adequately for the prediction and description of the retention indices of the volatile compounds.

    The rampant success of quantum theory is the result of applications of the 'new' quantum mechanics of Schrodinger and Heisenberg (1926-7), the Feynman-Schwinger-Tomonaga Quantum Electro-dynamics (1946-51), the electro-weak theory of Salaam, Weinberg, and Glashow (1967-9), and Quantum Chromodynamics (1973-); in fact, this success of 'the' quantum theory has depended on a continuous stream of brilliant and quite disparate mathematical formulations. In this carefully concealed ferment there lie plenty of unresolved difficulties, simply because in churning out fabulously accurate calculational tools there has been no sensible explanation of all that is going on. It is even argued that such an understanding is nothing to do with physics. A long-standing and famous illustration of this is the paradoxical thought-experiment of Einstein, Podolsky and Rosen (1935). Fundamental to all quantum theories, and also their paradoxes, is the location of sub-microscopic objects; or, rather, that the specification of such a location is fraught with mathematical inconsistency. This project encompasses a detailed, critical survey of the tangled history of Position within quantum theories. The first step is to show that, contrary to appearances, canonical quantum mechanics has only a vague notion of locality. After analysing a number of previous attempts at a 'relativistic quantum mechanics', two lines of thought are considered in detail. The first is the work of Wan and students, which is shown to be no real improvement on the iisu.al 'nonrelativistic' theory. The second is based on an idea of Dirac's - using backwards-in-time light-cones as the hypersurface in space-time. There remain considerable difficulties in the way of producing a consistent scheme here. To keep things nicely stirred up, the author then proposes his own approach - an adaptation of Feynman's QED propagators. This new approach is distinguished from Feynman's since the propagator or Green's function is not obtained by Feynman's rule. The type of equation solved is also different: instead of an initial-value problem, a solution that obeys a time-symmetric causality criterion is found for an inhomogeneous partial differential equation with homogeneous boundary conditions. To make the consideration of locality more precise, some results of Fourier transform theory are presented in a form that is directly applicable. Somewhat away from the main thrust of the thesis, there is also an attempt to explain, the manner in which quantum effects disappear as the number of particles increases in such things as experimental realisations of the EPR and de Broglie thought experiments.

    One of the most important issues in environmental conservation nowadays is the preservation of wetlands, mainly the coastal ones. This becomes more imperative in the Mediterranean. These particular ecosystems have suffered during the last decades an increasing human pressure. This has been reflected through the intensification of agriculture and construction of infrastructures in their surroundings or even draining part of them. As a result, the density of population and its residues affect them in a first place. This work has been developed in the Natural Park of La Albufera (Valencia, Spain), which includes a coastal lagoon, marshlands, dunes and pinewoods, surrounded by rice fields in its not urbanized part. In spite of this great ecological value, it suffers impacts derived from the high human and industrial occupation, and of the hydrological contributions from the connected irrigation systems. In addition, this park is one of the most important wetland in Europe, included in the RAMSAR agreement, being a key point for migratory birds and contains in its area one of the most important zones on rice production in Europe. In the park area, 28 sampling zones were selected to determine the degree of heavy metals incidence in soils. Total concentrations of Cd, Co, Cr, Cu, Ni, Pb, and Zn were evaluated. Their distribution in the surficial and sub-surficial horizons was determined together with their spatial distribution, and the possible sources of contamination. Zn, Cr and Cu show the highest concentrations in all land uses and zones. Cr is the metal that present maximum concentration in the studied area (254.93 ppm), being almost the only metal studied that exceeds the limits established by the Spanish an EU legislation. Co and Ni shows a tendency to accumulate below the 30 cm depth, the other metal studied continue with the cumulative trend in surface horizons. All the studied metals, except Co have highly significant correlations with the available phosphorous

    Full Text Available During the second half of the 20th century, in the littoral and pre-littoral areas of the Valencia region, the diurnal temperature range (DTR registered a significant drop in summer (July and August. Meanwhile, in the same period in the lower Ebro Valley (Ebro Observatory, to the north of the Valencia region, the maximum temperature and DTR increased steeply. In order to explain the DTR drop in the coastal areas of the Valencia region, some studies have proposed an increase in the summer sea-surface temperature (SST and others have attributed it to the urban heat island effect. Nevertheless, this drop occurred well before the current climate change was evident and therefore, before the rise of the SST. Furthermore, regarding the second proposed explanation, the drop in the DTR does not disappear when working with selected stations away from heavily urbanized areas. In this work, we propose that both the DTR rise at the Ebro Observatory and the DTR drop in the Valencia region are linked to the same process: changes in atmospheric circulation on a synoptic-scale in the North Atlantic that occurred in the late 1960s.

    Distribution of viable Candidatus Liberibacter asiaticus (CaLas) in sweet orange fruit and leaves ('Hamlin' and 'Valencia') and transcriptomic changes associated with huanglongbing (HLB) infection in fruit tissues are reported. Viable CaLas was present in most fruit tissues tested in HLB trees, with the highest titre detected in vascular tissue near the calyx abscission zone. Transcriptomic changes associated with HLB infection were analysed in flavedo (FF), vascular tissue (VT), and juice vesicles (JV) from symptomatic (SY), asymptomatic (AS), and healthy (H) fruit. In SY 'Hamlin', HLB altered the expression of more genes in FF and VT than in JV, whereas in SY 'Valencia', the number of genes whose expression was changed by HLB was similar in these tissues. The expression of more genes was altered in SY 'Valencia' JV than in SY 'Hamlin' JV. More genes were also affected in AS 'Valencia' FF and VT than in AS 'Valencia' JV. Most genes whose expression was changed by HLB were classified as transporters or involved in carbohydrate metabolism. Physiological characteristics of HLB-infected and girdled fruit were compared to differentiate between HLB-specific and carbohydrate metabolism-related symptoms. SY and girdled fruit were smaller than H and ungirdled fruit, respectively, with poor juice quality. However, girdling did not cause misshapen fruit or differential peel coloration. Quantitative PCR analysis indicated that many selected genes changed their expression significantly in SY flavedo but not in girdled flavedo. Mechanisms regulating development of HLB symptoms may lie in the host disease response rather than being a direct consequence of carbohydrate starvation.

    Full Text Available Debido al interés actual en la relación entre emoción y cognición, ha surgido la necesidad de contar con técnicas confiables de inducción emocional. Uno de los procedimientos más utilizados para el estudio experimental de la experiencia emo cional es la inducción de emociones mediante fragmentos de películas. El objetivo del estudio que se informa fue conocer las características subjetivas y objetivas de la respuesta emo cional ante estímulos audiovisuales inductores de emociones positivas y negativas, en una muestra de jóvenes argentinos. Se seleccionaron 20 fragmentos de películas (10 de valencia positiva y 10 de valencia negativa. La muestra estuvo integrada por 81 participantes (44 mujeres de 18 a 25 años (M = 21.20 ±2.57. La respuesta emocional subjetiva se evaluó con el Self-Assessment Manikin (Bradley & Lang, 1994 y la objetiva, registrando la fre cuencia cardíaca. La valencia, la activación y el control correlaciona ron en la mayoría de los fragmentos. Además, hom bres y mujeres presentan una reactividad diferenciada a la valencia de los estímulos, dado que las mujeres fueron más sensibles a los estímulos negativos (mutilaciones y animales amenazantes y los hombres, a los estímulos positivos (contenido erótico y cómico. Por último, la inducción emocional se mantuvo aproximadamente 30 minutos después de finalizada la pre sentación de los estímulos para los videos de valencia negativa y 15 minutos para los de valencia positiva. Se concluye que la investigación realizada constituye un aporte al estudio de las medidas subjetivas de la emoción y las características de la experiencia emocional en función del tiempo y del sexo de quienes la experimentan.

In Ciego de Avila University, Cuba, it was evaluated the effect of a leguminous cover crop on some properties of an orchard soil. The work was carried out during four years in an orange plantation of Valencia late (Citrus sinensis L. Osbeck in a 22 years-old orchard, with a plantation frame of 8 X 4 m, planted on a typical red Ferralitic soil, belonging to the CPA ¨José Martí¨, in Ciego de Avila. It was used a random block design with three treatments: one with covering of Teramnus labialis (T1, one with expontaneous vegetation (T2 and the third with no vegetation (T3. The functional structure properties of the soil were determined, and also the composition of macroaggregates expressed in the structure coefficient and the percentage of stable added in water, soil density, humidity and porosity. The increments in the humidity of the soil, the specific volume of pores and air, the structure coefficient, as well as the percentage of stable added in water, in the soil where the covering of Teramnus labialis was stablished, show the efficiency of cover crops in these citrus orchards.El uso de coberturas vivas de leguminosas en plantaciones citrícolas constituye una alternativa viable para el mejoramiento de las propiedades de los suelos, siempre que ellas se manejan adecuadamente en estas áreas.

    The effect of a repeated burning on soil hydrology and erosive parameters was studied on a Mediterranean forest soil (Rendzic leptosol) with the aim of identifying the effects of the fire and climatic parameters related to the post-fire runoff and soil loss. The study was carried out in an Experimental Permanent Field Station (La Concordia), close to Valencia (Spain). This field station is located on a calcareous hillside facing SSE, and is composed of nine erosion plots (20 × 4 m). Firstly, experimental fires were performed in June 1995 with two fire treatments (T1 or high severity fire and T2 or moderate severity fire) and a control one (unburnt, T3). The repeated fire (low severity) was carried out in July 2003. The studied period was focused from 18 months before the repeated fire (July 2003) until 18 months after it. Rainfall characteristics of each single event were recorded, which allowed us to statistically distinguish four time periods according to the rainfall intensity and duration: periods I (March 2002 to May 2003) and III (December 2003 to early May 2004) with low intensity and long duration rainfalls, and periods II (June 2003 to November 2003) and IV (late May 2004 to December 2004) with high intensity and short duration rainfalls. Before the 2003 fire, the partial recovery of soil and vegetation from the previous burning in 1995 led to a diminution in the runoff rates (6.5 L m - 2 in burned plots and 1.8 L m - 2 in unburnt ones). Six months later (period II), runoff increased in one order of magnitude (23.9 L m - 2 in burnt plots and 1.1 L m - 2 in the unburnt ones) due, in part, to the short time elapsed from fire until high intensity rainfalls. These differences in runoff production were maintained during the whole post-fire period. Fire effects were reflected in the erosion rates. Soil losses prior to the 2003 fire, in both fire treatments and in the control one, were scant relative to post-fire levels. However, six months after the repeated

  • Origin of intraformational folds in the Jurassic Todilto Limestone, Ambrosia Lake uranium mining district, McKinley and Valencia counties, New Mexico

    Science.gov (United States)

    Green, M.W.

    1982-01-01

    The Todilto Limestone of Middle Jurassic age in the Ambrosia Lake uranium mining district of McKinley and Valencia Counties, New Mexico, is the host formation for numerous small- to medium-sized uranium deposits in joints, shear zones, and fractures within small- to large-scale intraformational folds. The folds probably were formed as a result of differential sediment loading when eolian sand dunes of the overlying Summerville Formation of Middle Jurassic age migrated over soft, chemically precipitated, lime muds of the Todilto shortly after their deposition in a regressive, mixed fresh and saline lacustrine or marine environment of deposition. Encroachment of Summerville eolian dunes over soft Todilto lime muds was apparently a local phenomenon and was restricted to postulated beltlike zones which trended radially across the Todilto coastline toward the receding body of water. Intraformational folding is believed to be confined to the pathways of individual eolian dunes or clusters of dunes within the dune belts. During the process of sediment loading by migrating sand dunes, layers of Todilto lime mud were differentially compacted, contorted, and dewatered, producing both small- and large-scale plastic deformation structures, including convolute laminations, mounds, rolls, folds, and small anticlines and synclines. With continued compaction and dewatering, the mud, in localized areas, reached a point of desaturation at which sediment plasticity was lost. Prolonged loading by overlying dune sands thus caused faulting, shearing, fracturing, and jointing of contorted limestone beds. These areas or zones of deformation within the limestone became the preferred sites of epigenetic uranium mineralization because of the induced transmissivity created by sediment rupture. Along most of the prograding Todilto coastline, adjacent to the eolian dune belts, both interdune and coastal sabkha environments dominated during Todilto-Summerville time. Sediments in coastal areas

    Full Text Available La estabilidad dinámica de una columna elástica prismática esbelta con conexiones semirrígidas en ambos extremos de rigidez idéntica y con desplazamiento lateral entre los dos extremos totalmente inhibido sujetos a cargas axiales paramétricos incluyendo los efectos combinados de inercia rotacional y amortiguación externas se investiga de una manera clásica. Expresiones cerradas que se pueden utilizar para predecir las regiones de inestabilidad dinámica de columnas esbeltas son desarrolladas haciendo uso de la teoría de Floquet. La solución propuesta es capaz de capturar el fenómeno de estabilidad en columnas sometidas a cargas axiales periódicas utilizando un solo elemento de columna. El método propuesto y las ecuaciones correspondientes se pueden utilizar para investigar los efectos del amortiguamiento, la inercia rotacional de la columna, y las conexiones semirrígidas en el análisis de estabilidad de columnas esbeltas sometidas a cargas axiales periódicas. Los efectos producidos por las deformaciones por cizallamiento a lo largo de la columna, así como los producidos por la inercia axial, el acoplamiento entre las deflexiones longitudinales y transversales y la curvatura no se tienen en cuenta. Estudios de sensibilidad que muestran los efectos de la inercia rotacional, el amortiguamiento y las conexiones semi-rígidas en la estabilidad dinámica de columnas sometidas a cargas axiales paramétricas son presentados en una publicación adjunta.

The samples were obtained from a leader industry of the chilean market. The potatoes were evaluated until the panel detected significant difference (0.05>p for «strange» odour and flavour. Chemical evaluation was performed on the oil extracted from the potatoes. Sensory evaluation showed significant differences (0.05>p against control at 48, 72 and 9 days of storage at daylight and darkness room temperature, and 40ºC respectively. During the frying process about 80% of terbutilhydroquinone (TBHQ was lost, delta and gamma tocopherol decreased around 43 and 30% respectively. Thermic deterioration was the most important during frying while only oxidation increased during storage. A relationship between sensory and chemical deterioration was established. It was found that, for the same polar compound percentage, a period of time around 7 times higher was necessary at room temperature in darkness, than at 40ºC.Se evaluó la progresión del deterioro de papas crisps almacenadas a temperatura ambiente en presencia de luz y en oscuridad, así como 40ºC y –23ºC (control en oscuridad.

    .Objective: Pneumococcal disease is an important cause of morbidity and mortality in children. The recent authorization of the heptavalent conjugate vaccine has increased interest in this disease. The objective of this study was to identify the epidemiological and clinical characteristics of this disease, as well as its outcome in the pediatric population of the Autonomous Community of Valencia. Method: Data were obtained from the medical records of children aged less than 15 years who were positive for pneumococcus isolation on admission to hospital between 1996 and 2000. All the public hospitals of the Autonomous Community of Valencia were included. Changes in incidence were evaluated by comparing rates and outcomes (sequelae and lethality through frequency and age distribution. Results: One hundred twenty-seven cases were registered, giving a mean annual rate of 3.89/105 inhabitants aged less than 15 years. The rate was 20.14 in children aged less than 2 years. A total of 29.1% of the children had previous health problems. The main clinical manifestations included sepsis/bacteremia (38%, pneumonia (31% and meningitis (24%. At discharge sequelae were present in 10 children, 75% of whom were aged less than 2 years. Eight children died (6.3% lethality. Conclusions: In the period and region studied, pneumococcal infection was present mainly in children aged less than 2 years and in those with previous health problems. In the last few years, mortality has increased. Thus, inclusion of pneumococcal disease in the epidemiological surveillance system would be appropriate to achieve more precise estimations of its epidemiological patterns and to determine whether the conjugate vaccine represents a solution to the problems currently associated with this bacteria.

Conduziu-se este estudo, com o objetivo de avaliar componentes do desenvolvimento e do estado nutricional de mudas de laranjeira Valência (Citrus sinensis Osbeck, enxertadas sobre limoeiro Cravo (Citrus limonia Osbeck, em função de doses de nitrogênio, fósforo e potássio. O delineamento experimental foi inteiramente casualizado, em esquema fatorial 3³ + 1, sendo 3 fatores (nitrogênio, fósforo e potássio - NPK, 3 doses e uma testemunha (sem adubação, com 3 repetições. A unidade experimental foi representada por uma muda de laranjeira por sacola com 5 dm³ com 2,5 kg de substrato casca de Pinus spp. e vermiculita. Os tratamentos foram constituídos pela metade, uma vez e duas vezes a dose padrão recomendada, de 4.590; 920 e 4.380 mg sacola-1, de N, P e K, respectivamente. As adubações com N e K foram realizadas via fertirrigações três vezes por semana e o P foi adicionado ao substrato antes do replantio das mudas. Aos 424 dias após o transplantio, as plantas foram subdivididas em raízes e parte aérea para determinação da massa da matéria seca, altura, área foliar, diâmetro do caule e conteúdo de nutrientes. A adubação com N, P e K proporcionou maior desenvolvimento e maior acúmulo desses macronutrientes na parte aérea e nas raízes das mudas de laranjeira Valência, sobre limoeiro Cravo. Houve adequado desenvolvimento das plantas com a metade da dose recomendada de N, P e K pela literatura, aproximadamente de 918, 184 e 876 mg dm-3, respectivamente.The experiment was carried out in greenhouse at the FCAV/Unesp, Jaboticabal-SP during the period of November 2005 to January 2007.

    Full Text Available Estudou-se o efeito da infecção pela bactéria Xylella fastidiosa, agente causal da Clorose Variegada dos Citros (CVC, sobre a taxa de ingestão de seiva do xilema de plantas cítricas por duas espécies de cigarrinhas vetoras (Hemiptera: Cicadellidae. Foram utilizados pés-francos de laranjeira-doce (Citrus sinensis das variedades 'Pêra' e 'Valência', infectadas por X. fastidiosa da linhagem 9a5c, por meio de inoculação mecânica. Os insetos utilizados nos experimentos foram coletados em campo, sendo um representante da Tribo Cicadellini (Dilobopterus costalimai e um da Proconiini (Oncometopia facialis. A taxa de ingestão de seiva do xilema por O. facialis foi quantificada nos ramos das plantas e a de D. costalimai nas folhas e ramos, por meio da avaliação do volume do líquido (honeydew excretado por unidade de tempo. O consumo pela cigarrinha O. facialis nas plantas doentes foi menor do que nas plantas sadias. Na variedade 'Pêra' doente, o consumo foi baixo, não permitindo a quantificação da seiva eliminada. Na 'Pêra' sadia e na 'Valência' doente e sadia, O. facialis apresentou valores expressivos de excreção, com maior alimentação no período diurno. Nas plantas sadias das duas variedades, o consumo pela cigarrinha D. costalimai foi maior do que nas plantas com CVC. Comparando-se as variedades, o consumo foi superior na variedade 'Valência', e, em relação às partes da planta, folha e ramo, a taxa de ingestão foi maior no ramo das duas variedades, apresentando consumo maior no período diurno.It was studied the effect of Xylella fastidiosa infection, causal agent of Citrus Variegated Chlorosis (CVC, on the xylem sap ingestion rate of citrus plants by two sharpshooters species (Hemiptera: Cicadellidae.

    Full Text Available Fundamentos: El personal sanitario está expuesto a enfermedades prevenibles por vacunación y por tanto, asegurar una adhesión a programas de vacunación es un elemento clave en la prevención de las infecciones adquiridas en el trabajo y evitar causar daño a los pacientes. Los objetivos fueron estimar la prevalencia de anticuerpos frente a sarampión, rubeola y parotiditis entre los facultativos del Área Clínica de Enfermedades del Niño del Hospital Universitario y Politécnico la Fe de Valencia y estudiar su relación con antecedentes de la enfermedad, vacunación y categoría y experiencia profesional. Métodos: Estudio observacional transversal analítico. A todos los participantes se les realizó un análisis serológico para la detección de anticuerpos específicos frente a sarampión, rubeola y parotiditis y se les ofreció la posibilidad de cumplimentar un cuestionario sobre antecedentes de enfermedad y/o vacunación. Se realizó un análisis descriptivo y de relación para cada una de las enfermedades. Resultados: Participaron 97 facultativos, de ellos presentaban serología positiva para sarampión 75 (77,3%, para rubeola 85 (87,6% y 68 (70,1% frente a parotiditis. El modelo de regresión logística mostró diferencias significativas en la prevalencia de anticuerpos frente a sarampión en función de la edad (OR 1,22 y frente a rubeola en función del sexo (OR 5,16. Conclusiones: Considerando la alta prevalencia de facultativos jóvenes seronegativos y teniendo en cuenta la actividad profesional que desarrollan, la vacunación en este colectivo estaría recomendada por lo que sería conveniente diseñar estrategias para conseguir la adhesión de los profesionales al programa de vacunación.

    Full Text Available Son numerosas las investigaciones que desde hace más de dos décadas han investigado posibles influencias de género en el comportamiento en la empresa y en los estilos de dirección. Sin embargo, en el análisis no se han contemplado los aspectos institucionales y organizativos, que juegan un papel relevante en el comportamiento y en el trabajo de los directivos. Atendiendo a lo anterior, este trabajo muestra las implicaciones organizativas que tiene la forma institucional Cooperativa de trabajo asociado (CTA y cómo afectan al trabajo directivo. Asimismo, y desde una perspectiva de género, se investigan en CTAs valencianas las capacidades directivas vinculadas a diferencias de género. Los resultados obtenidos sugieren que la naturaleza del trabajo que realizan las directivas (mujeres, así como su visión del trabajo directivo responde a un estilo directivo contemporáneo, y tienen un mayor “encaje” con el contexto organizativo de la CTA caracterizado por relaciones entre iguales. / In the last two decades, much research has been done regarding gender differences and leadership styles. This paper presents some of the organizational implications of cooperative firms (Coops and how their characteristics affect the leadership style of managers. Also, from a gender perspective, we study the management style associated with gender differences in Coops in Valencia (Spain. The results suggest that the nature of the work done by women managers, and their vision of management, responds to a more contemporary leadership style, and fits better in the organizational context of coops, which are characterized by equal relations.

    Full Text Available Diagnosis and Recommendation Integrated System (DRIS applies nutrient ratios instead of the isolated concentration values of each nutrient in interpretation of tissue analysis. The objectives of this research were to establish adequate DRIS norms for 'Valencia' sweet orange irrigated commercial groves budded on three rootstocks and correlate indexes of nutrition balance with yield. Experiments were conducted in São Paulo State, Brazil. Rootstocks Rangpur lime, Caipira sweet orange, and Poncirus trifoliata, with more than six years old and yield above 40 ton ha-1 were utilized. Data referred to yield, tree spacing, rootstock and foliar concentrations of N, P, K, Ca, Mg, S, Fe, Mn, Cu, Zn, and B in non fruiting terminals for each grove were processed for the years 1994 through 1998. DRIS indexes were calculated by Nick criterion for choosing the ratio order of the nutrients and Jones calculation method of the ratio functions. Indexes of nutritional balance calculated from DRIS norms presented high correlation with yield for the three scion/rootstock combinations. DRIS norms defined in this research are valid, since leaf sampling is done on non fruiting terminals and the grove is irrigated.O sistema integrado de diagnose e recomendação (DRIS - Diagnosis and Recommendation Integrated System utiliza relações entre nutrientes em vez da concentração absoluta e isolada de cada um deles na interpretação da análise de tecidos. O objetivo deste trabalho foi estabelecer normas para o método DRIS em pomares comerciais irrigados de laranjeira 'Valência' sobre três porta-enxertos e correlacionar os índices de balanço nutricional com a produtividade. Os experimentos foram conduzidos no Estado de São Paulo, com os porta-enxertos limão 'Cravo', laranja 'Caipira' e Poncirus trifoliata, com mais de seis anos, e produtividade acima de 40 t ha-1.
