Agricultural Sciences (AS) , 2016, DOI: 10.4236/as.2016.77048
Abstract: The increase of human population generates the need to improve the efficiency of food production. A thorough planning is required following the scope of economic and sustainable development, being irrigation a basic tool, however water availability is restricted and it obliges farmers to progress increasing water productivity. Irrigation uses around 70% of total available fresh water, while irrigation water application efficiency is around 40%. Irrigation systems must follow strong criteria at the design stage to achieve high values of water productivity. Maintenance is indispensable to follow the original functioning level of those systems. At last the daily precise management of systems, following soil water potential, considering the effective rain storage at root depth of the crop and the evolution of daily evapotranspiration, preserving natural resources, are relevant to achieve low values of water footprint of this crop. In an 8 year drip irrigation system, the Uniformity Coefficient of Christiansen (UCC) measured was 95.14%; the Uniform Coefficient of the Minor Quart (UCMQ) was 93.16%. The Total Distribution Efficiency (EDT) was 95.13% when measurements finished while the irrigation systems is of. When measurements also considered the volume collected during the “recession phase in drip irrigation” and the “volume of water collected during recession phase in drip irrigation” collected at different points, EDT was 95.13%. Moreover it can be seen that when three different typical soil of the area were considered, the EDT was, 91.85%, 91.47% and 90.30% respectively, according with different water storage capacity of each soil. The Total Distribution Efficient is a strong method, to evaluate the design and management of drip irrigation systems, under different design criteria, management practices and maintenance of the systems. Water footprint in a blueberry (Vaccinium corymbosum L.) crop with drip and sprinkler anti-frost system, were measure and values obtained were 846, 310, 223, 212, 172 and 218 liters per kg of fresh fruit in the period 2010-2015. The UCC and the UCMQ reflects properly the irrigation design, while the EDT reflects irrigation design, management and maintenance. Water footprint is at last the strong tool to evaluate design and operation of the irrigation system and crop management.

Abstract:

Background: In Bolivia there are few probiotic preparations available in the market, practically without alternatives to the use of freeze-dried products. An alternative used as a good alternative in other parts of the world is yogurt with a probiotic strain added. In this study we report the use of a locally prepared yogurt with a lyophilized probiotic added. Methods: This is randomized, double-blind and controlled clinical trial in children hospitalized with acute diarrhoea carried out at the Paediatric Centre Albina Pati?o in Cochabamba, Bolivia with children 10 to 35 months participating. Children were randomly assigned to receive an oral rehydration solution and Saccharomyces boulardii (positive control) or the same solution plus yogurt preparation containing Lactobacillus rhamnosus (yogurt group). The primary outcome was the duration of diarrhoea. Secondary outcomes were the duration of fever, vomiting and hospitalization. Results: Of the 74 children incorporated 42 completed the protocol; baseline characteristics were similar in both groups. The median duration of diarrhoea was similar in children who received yogurt (71 hours) and controls (79 hours) (p = 0.3). The mean duration of fever was also similar in both groups: S. boulardii (24 hours) or yogurt (11 hours) (p = 1.02), as was the duration of vomiting: 17 hours vs. 32 hours in the control group

Abstract: the effects of spontaneous (sv) and controlled ventilation (cv) were compared in horses undergoing changes in body position during anesthesia. sixteen animals were equally distributed in two groups: sv and cv. all surgical procedures were commenced on left lateral recumbency (llr) and 75 minutes later the animals were repositioned on right lateral recumbency (rlr). arterial blood gas analyses were performed at 30 and 75 minutes after each recumbency (m1 and m2 for llr and m3 and m4 for rlr). hypercapnia (paco2 >45mmhg), respiratory acidosis (ph <7.35), and significant decrease in pao2 after 75min of change in body position (m4: 205.8±124.7mmhg) in comparison to pao2 values before the change of position (m1: 271.8±84.8mmhg) were observed during sv. when compared to the sv group, cv resulted in significantly higher pao2 levels (52 to 96% increase). it was concluded that the change in the body position in spontaneously ventilating halothane-anesthetized horses causes impairment in arterial oxygenation. the use of cv since the beginning of anesthesia prevents the respiratory acidosis and maintains arterial oxygen levels that are closer to values expected during the use of 100% o2.

Abstract: by approving regulation 1606/2002, the european commission entrusts the local european union regulators with the difficult decision as to whether making the international accounting standards (ias/ifrs) extensive for their small and medium-sized entities or not. international financial reporting standard for small and medium-sized entities (hereinafter ifrs for smes) was published in 2009, and the european commission had also decided to seek the opinion of eu stakeholders on this standard. we understand that the european accounting regulators' position should be based on the analysis of the extent to which current domestic standards allow useful financial information to be provided by and to these companies. therefore, this paper presents empirical evidence regarding spanish smes' characteristics, timely facing the harmonization process, in order to determine if the information provided according to the national standards accomplishes the required usefulness. its purpose is to share facts and data about this kind of still underestimated companies, though of great economic and social significance in spain and in europe in general.

Abstract: Con la aprobación del Reglamento 1606/2002, la Comisión Europea dejó en manos de los reguladores europeos la difícil tarea de decidir entre exigir o no a sus peque as empresas la aplicación de las normas internacionales de contabilidad (nic/niif). La ifrs for Private Entities elaborada por el iasb fue publicada en 2009 y ya ha sido sometida a la opinión de los stakeholders de la Unión por parte de la Comisión Europea. Ante esta situación la posición por adoptar al respecto por los reguladores comunitarios debería basarse en el análisis del grado de utilidad de la información financiera elaborada por sus Pyme con la información doméstica actual. Es por ello que este trabajo ofrece evidencia empírica en relación con las características de las Pyme frente al proceso armonizador con la intención de determinar si la información proporcionada con la normativa nacional permite dar cumplimiento al objetivo de utilidad. El propósito perseguido es aportar luz acerca de este tipo de entidades aún muy desconocidas a pesar de su gran importancia económica y social en Espa a y en toda Europa.

Abstract: Two species of small-medium size felids, Felis aff. silvestris and Caracal depereti nov. sp., have been identified from the Pliocene karstic locality of Layna (Soria, Spain). Caracal depereti nov. sp. shows close affinities with Caracal issiodorensis, species that has been traditionally classified in the genus Lynx. This new interpretation implies that there are no evidences of lynxes in the Pliocene of Westem Europe, and probably this consideration can be applicable to other Eurasiatic localities where Lynx issiodorensis has been determined. Dos especies de félidos de talla peque a a media, Felis aff. silvestris y Caracal depereti nov. sp., han sido identificadas en el yacimiento cárstico plioceno de Layna, Soria. Caracal depereti nov. sp. muestra estrechas afinidades con Caracal issiodorensis, especie que tradicionalmente ha sido clasificada en el género Lynx. Esta interpretación implica que no hay evidencias de linces en el Plioceno de Europa occidental, y probablemente esta consideración pueda aplicarse a otros yacimientos pliocenos de Eurasia, en los que se ha determinado Lynx issiodorensis.

Abstract: In the Rojales area, at the southem border of the Low Segura Basin (province of Alicante), we have studied four formations already defined by Montenat (1973, 1977). All of them constitute a continue stratigraphic succession and represent a general regressive sequence, where open basin facies (Hurchillo Marls Fm.), shelf and coastal facies (Rojales Sandstone Fm.) and continental facies (Variegated Sandstones and Marls Fm. and Segura Conglomerates Fm.) gradually evolve from the bottom to the topo The biostratigraphic data of planktonic foraminifera allows the date the top of the Hurchillo Marls Fm. as the upper part of the lower Pliocene (NI9-N2ü of the Blow zonation). The study of a new site of microvertebrates, named as Rojales, allows the dating the top of the Variegated Sandstones and Marls Fm. (in the transition with the Segura Conglomerates Fm.) as upper Ruscinian (start of MN15 of the Mein biozonation). These chronological data show that the whole stratigraphic succession of the Rojales area has a age corresponding to the final part of the lower Pliocene. En el sector de Rojales (Alicante), situado en el borde meridional de la Cuenca del Bajo Segura, se han estudiado cuatro formaciones ya definidas por Montenat (1977). Todas ellas se suceden en continuidad estratigráfica y representan una secuencia general regresiva en la que evolucionan gradualmente (desde la base hasta el techo) conjuntos de facies marinas de cuenca abierta y de transición a plataforma (Fm. Margas de Hurchillo), de plataforma y litorales (Fm. Areniscas de Rojales) y continentales (Fm. de Areniscas y Margas Versicolores y Fm. Conglomerados del Segura). Los datos biostratigráficos basados en foraminíferos planctónicos permiten asignar el techo de la Fm. Margas de Hurchillo a la parte más alta del Plioceno inferior (intervalo N19-N2ü de la zonación de Blow). El estudio de los microvertebrados de un nuevo yacimiento, denominado yacimiento de Rojales, situado en el tránsito entre la Fm. Areniscas y Margas Versicolores y la Fm. Conglomerados del Segura, permite datar el Rusciniense superior basal (comienzo de la biozona MN15 de Mein). Estos datos cronológicos indican que toda la sucesión estratigráfica de Rojales presenta una edad Plioceno inferior muy alto.

Abstract: In the Neogene sediments of the Lower Segura Basin (Eastern Betic Cordillera) have been studied three localities with fossil micromammals. They yielded a fauna which date the stratigraphic units MS-IV (Upper Tortonian-Messinian) and P-I (Lower Pliocene). The two older, named Castro and Pantano de Elche (Pantel) date the base of the Upper Turolian (zone MNI2) and the Ventian (zone MN13) respectively; they both belongs to the unit MS-IV. The younger one, locate in the Barranco de Fayona (Fayona) indicates a Lower Ruscinian age (zone MNI4) of the unit P-I, which was considered until now as Upper Pliocene. En este trabajo se estudian tres yacimientos de microvertebrados dentro de los materiales neógenos que rellenan la Cuenca del Bajo Segura (Cordillera Bética oriental). Estos permiten precisar la edad de las Unidades estratigráficas MS-IV (Tortoniense terminal - Messiniense o Turoliense inferior parte alta - Ventiense) y P-I (Plioceno inferior). Los dos más bajos, denominados Castro y Pantano de Elche (Pantel), datan la base del Turoliense superior (zona MNI2) y el Ventiense (zona MNI3), respectivamente; ambos se encuentran en la unidad MS-IV. El yacimiento más moderno, denominado Barranco de Fayona (Fayona) data el Rusciniense inferior (zona MNI4) y se encuentra asociado a un conjunto hasta el momento considerado de edad Plioceno superior.
