Development of procedures for the triazole fungicides determination in fruits and liquid samples using microextraction techniques and chromatographic separation

Agricultural crops can be damaged by funguses, insects, worms and other organisms that cause diseases and decrease the yield of production. The effect of these damaging agents can be reduced using pesticides. Among them, triazole compounds are effective substances against fungus; for example, Oidium. Nevertheless, it has been detected that the residues of these fungicides in foods as well as in derivate products can affect the health of the consumers. Therefore, the European Union has established several regulations fixing the maximum residue of pesticide levels in a wide range of foods trying to assure the consumer safety. Hence, it is very important to develop adequate methods to determine these pesticide compounds. In most cases, gas or liquid chromatographic (GC, LC) separations are used in the analysis of the samples. But firstly, it is necessary to use proper sample treatments in order to preconcentrate and isolate the target analytes. To reach this aim, microextraction techniques are very effective tools; because allow to do both preconcentration and extraction of the analytes in one simple step that considerably reduces the source of errors. With these objectives, two remarkable techniques have been widely used during the last years: solid phase microextraction (SPME) and liquid phase microextraction (LPME) with its different options. Both techniques that avoid the use or reduce the amount of toxic solvents are convenient coupled to chromatographic equipments providing good quantitative results in a wide number of matrices and compounds. In this work simple and reliable methods have been developed using SPME and ultrasound assisted emulsification microextraction (USAEME) coupled to GC or LC for triazole fungicides determination. The proposed methods allow confidently determine triazole concentrations of μg L‐1 order in different fruit samples. Chemometric tools have been used to accomplish successful determinations. Firstly, in the selection and optimization of the variables involved in the microextraction processes; and secondly, to overcome the problems related to the overlapping peaks. Different fractional factorial designs have been used for the screening of the experimental variables; and central composite designs have been carried out to get the best experimental conditions. Trying to solve the overlapping peak problems multivariate calibration methods have been used. Parallel Factor Analysis 2 (PARAFAC2), Multivariate Curve Resolution (MCR) and Parallel Factor Analysis with Linear Dependencies (PARALIND) have been proposed, the adequate algorithms have been used according to data characteristics, and the results have been compared. Because its occurrence in Basque Country and its relevance in the production of cider and txakoli regional wines the grape and apple samples were selected. These crops are often treated with triazole compounds trying to solve the problems caused by the funguses. The peel and pulp from grape and apple, their juices and some commercial products such as musts, juice and cider have been analysed showing the adequacy of the developed methods for the triazole determination in this kind of fruit samples.

La violencia contra la pareja o expareja mujer: un estudio de la variable de la nacionalidad en la base de datos de la Guardia Municipal de Donostia/San Sebastian

[ES]Este Trabajo de Fin de Grado (TFG) está relacionado con las prácticas efectuadas en la Guardia Municipal de San Sebastián (País Vasco) y pretende analizar las órdenes de protección concedidas a víctimas de violencia de género inmigrantes y nacionales para comprobar si existe alguna diferencia en cuanto a su aplicación. Asimismo, se pretende analizar el procedimiento efectuado por este cuerpo policial y servicios sociales en estos casos, así como el perfil de la víctima y el agresor. Por otra parte, se procura analizar aspectos controvertidos de la Ley Orgánica 1/2004 de Medidas de Protección Integral de la Violencia de Género. Para ello, se utilizara una metodología mixta. Por una parte de corte cualitativo realizando cuatro entrevistas (a dos víctimas, una agente de policía y una trabajadora social) para ahondar más respecto a este tema. En segundo lugar, desde una perspectiva cuantitativa se explorará la base de datos de la Guardia Municipal en materia de violencia de género para realizar un análisis estadístico. Finalmente, se abordaran las conclusiones a las que se ha llegado con este trabajo y se propondrán mejoras de cara a futuras investigaciones y a la operatividad de la Guardia Municipal.

Desarrollo Sostenible y Espacios Naturales Protegidos: el caso de la Reserva de la Biosfera de Urdaibai

En este Trabajo Fin de Grado se analiza el desarrollo y evolución de los Espacios Naturales Protegidos en el marco del concepto de Desarrollo Sostenible. Se ha tratado de mostrar la evolución en el tiempo y en los fines llevada a cabo por estos Espacios, tanto desde el ámbito internacional como europeo, nacional y local, deteniéndose, especialmente, en el estudio de la Reserva de la Biosfera de Urdaibai, al considerarse uno de los elementos más representativos de Euskadi. Con este trabajo, se confirma la hipótesis de que, aunque en la declaración y protección de Espacios Naturales se aprecia un esfuerzo realizado notable, aún queda un largo camino por recorrer.

Two new species of Zospeum Bourguignat, 1856 from the Basque-Cantabrian Mountains, Northern Spain (Eupulmonata, Ellobioidea, Carychiidae)

Two new species of the genus Zospeum Bourguignat, 1856 are described from caves in the Sierra de Aitzgorri (Gipuzkoa) and the Sierra Salvada (Burgos) in Northern Spain. The taxa Z. vasconicum sp. n. and Z. zaldivarae sp. n. have recently, without a formal name, been included in a molecular study of worldwide members of the Carychiidae. In the present paper, the shell morphology and variation of these species is described and illustrated.

Factors Facilitating Successful Educational Innovation with ICT in Schools

[EN]This paper proposes an approach to the concept of ICT-based innovation in schools, from the perspective of the factors that facilitate the innovative use of ICT. To this end, a scale has been developed and validated to identify these factors through the participation of 195 teachers from 16 schools considered by the Basque educational authorities as innovators in ICT. The results obtained attest to the validity and reliability of both the scale and the 5 key factors that influence innovation in technology-based teaching. This factor-based structure enables a holistic view of ICT innovation in schools across 3 key areas: school context, teachers and the education authorities.
