Este proyecto de innovación educativa se realiza en el CIEP Tomás Romojaro de Olmedo. El objetivo general es dinamizar la biblioteca, para suscitar el interés por la lectura de los alumnos con actividades lúdicas y educativas, dirigiendo el proyecto a la celebración del IV Centenario de la Publicación de 'El ingenioso hidalgo Don Quijote de la Mancha'. La mayoría del profesorado del centro se ha implicado en que dicho proyecto se realizara, además han colaborado las familias en algunas actividades. El trabajo se ha desarrollado fundamentalmente dentro del propio centro educativo, excepto una visita a la casa de Don Miguel de Cervantes en Valladolid. Los objetivos generales del proyecto son los siguientes: - Dinamizar el uso de la biblioteca. - Comprender pequeños textos y mensajes orales y escritos. - Expresarse oralmente de una forma coherente.- Conocer y valorar el propio cuerpo experimentando sus posibilidades motrices. - Favorecer y encauzar la expresividad infantil. - Posibilitar la comunicación, sociabilidad y relación grupal.- Favorecer la interculturalidad a través del conocimiento de textos escritos de otros países de origen de alumnos del centro.- Celebrar el IV Centenario de la publicación del Quijote. La metodología llevada a cabo ha sido activa, lúdica para motivar y dinamizar al máximo los aprendizajes de los alumnos, potenciando su participación. El equipo de profesores ha llevado un plan de trabajo estructurado con un reparto de tareas definido y equilibrado. Han trabajado en dos niveles, en pequeños grupos, por ciclos, para la realización de las tareas acordadas y en grupo general para consensuar las actuaciones y proponer otras nuevas. El plan de trabajo concreto ha sido el siguiente: 1) Los profesores responsables de la biblioteca han llevado acabo unas sesiones de información para todos los profesores participantes en este proyecto, sobre los libros que hay en la biblioteca, lugar de ubicación de los mismos y a los niveles a los que están dirigidos. 2) Plantear lecturas adecuadas según la época del año y lo que se quiera conmemorar. 3) Establecer tiempos de utilización de la biblioteca por los diferentes grupos, organizar el préstamo de libros. 4) Elaboración de materiales. 5) Llevar a cabo todas las actividades propuestas. La evaluación se lleva a cabo durante todo el proceso del proyecto:al inicio haciendo un análisis de la situación de partida; durante el proyecto evaluación continua basada en la observación directa de todas las acciones realizadas, corrigiendo errores si fuera necesario, ya que en todo momento se tiene en cuenta el progreso de los alumnos, su actitud hacia la actividad, el análisis de la metodología empleada, tiempos y materiales utilizados. Los criterios de evaluación utilizados son: Lectura de textos utilizando la entonación y el ritmo adecuados, consolidando la habilidad lectora y apreciándola como fuente de información, placer y entretenimiento; comprensión del sentido global de los textos escrito; manifestación de preferencias en la selección de lecturas y expresión de las propias opiniones y gustos personales sobre los textos leídos; participación de forma constructiva (escuchar, respetar las opiniones de los demás y aportar opiniones razonadas) en diálogos, debates o exposiciones; utilización de la lengua oral y escrita en diferentes situaciones comunicativas; utilización de algunos recursos dramáticos y expresivos básicos (títeres, teatro danzar y canciones); comprensión d el sentido global de textos orales y escritos en inglés y francés; representación con imágenes secuenciadas, cómic o historieta, personajes y objetos. Los materiales elaborados han sido los siguientes: fichero con la relación de todas las actividades llevadas a cabo, libro de colorear nuestros dibujos del Quijote, carpeta con refranes en el Quijote, maqueta del Quijote para el aula del centenario, carpeta con diccionario de El Quijote, cajas de vocabulario decoradas, reportaje fotográfico de la experiencia, incluido en distintos CD-R.

This study presents the results of the degradation of the pesticide atrazine using electrochemical and photo-assisted electrochemical degradation techniques using SnO(2)-containing electrode of nominal composition electrodes of composition Ti/Ru(x)Sni-(x)O(2) (where X = 0.10, 0.15, 0.20, 0.25 and 0.30). The materials were characterized ex situ and in situ in order to correlate the observed atrazine removal rates with electrode morphology/composition. The results obtained demonstrate the effectiveness of the photo-assisted electrochemical degradation. Using purely electrochemical methods the rate of atrazine removal is almost zero at all the electrodes studied. However, the application of photo-assisted degradation results in almost complete atrazine removal in 1 h of electrolysis. The efficiency of atrazine degradation does not seem to be greatly affected by the electrode material or by SnO(2) content, but the overall COD removal is dependent on the SnO(2) content. Overall, the SnO(2)-containing electrodes do not reach the level of COD removal (maximum similar to 21%) seen for the Ti/Ru(0.3)Ti(0.2)O(2) electrode. An interesting correlation between the morphology factor (phi) and chemical oxygen demand removal is observed. (C) 2010 Elsevier B.V. All rights reserved.

This case study objectified investigating the symptomatology prevalence for depression (DP) and cognitive decline (CD) on institutionalized elderly’s; verifying the existence of correlations between DP and CD with age, gender and scholarity; and analyzing the possible correlations between symptomatology for DP and CD. For the realization of this research were selected, in two Elderly’s Long-Permanence Institutions (ELPIs), 24 subjects, which were classified according to gender, scholarity and age group. To verify the occurrence of CD, the Mini Mental State Examination (MMSE) was applied and, for the incidence of DP, the Geriatric Depression Scale (GDS) was applied. The data were tabulated and descriptively analyzed. For the study of the relations between quantitative variables, the Pearson correlation test was utilized and also the Spearmann test when necessary; for the comparison between two independent groups, the Student's t-test was utilized; for the verification of the association between gender, scholarity, DP and CD indicatives, the Pearson's X2 test and, due to theoretical restriction, the Fisher's exact test were utilized. The level of 5% probability was adopted for the rejection of nullity's hypothesis on all the tests. The research demonstrated that 50% of the research' subjects presented DP indicatives and 54.2% presented CD indicatives. Associations between: gender and DP (p = 0.414), gender and CD (p = 0.219), scholarity and CD (p = 0.527) were not observed. Positive regular correlation was verified between age and DP (r = 0.557; p = 0.005) and negative regular correlation was verified between DP and CD (r = -0.406; p = 0.049). The data suggest that DP might be a reaction to CD perceived by the subject. However, the hypothesis that indicates DP as a risk factor for CD and DM cannot be overruled, which suggests the importance of monitoring and treating depressive episodes on elderly populations.
Application of Electrochemical Degradation of Wastewater Composed of Mixtures of Phenol-Formaldehyde

The industrial wastewater from resin production plants contains as major components phenol and formaldehyde, which are traditionally treated by biological methods. As a possible alternative method, electrochemical treatment was tested using solutions containing a mixture of phenol and formaldehyde simulating an industrial effluent. The anode used was a dimensionally stable anode (DSAA (R)) of nominal composition Ti/Ru0.3Ti0.7O2, and the solution composition during the degradation process was analyzed by liquid chromatography and the removal of total organic carbon. From cyclic voltammetry, it is observed that for formaldehyde, a small offset of the beginning of the oxygen evolution reaction occurs, but for phenol, the reaction is inhibited and the current density decreases. From the electrochemical degradations, it was determined that 40 mA cm(-2) is the most efficient current density and the comparison of different supporting electrolytes (Na2SO4, NaNO3, and NaCl) indicated a higher removal of total organic carbon in NaCl medium.

A szerzők cikkükben a számítástechnikai hulladékokkal foglalkoznak, számítástechnikai eszközök alatt a számítógép konfigurációk összetevőit értik, tehát számítógépeket (asztali, hordozható, terminál stb.), és perifériáit (monitor, nyomtató, cd-író stb.), valamint ezek alkatrészeit és kiegészítőit (chipek, mechanikus részek, festékkazetták stb.). A rendszeres használat környezeti hatásait csak abból a szempontból vizsgálták, hogy ennek során bizonyos alkatrészek, kellékek (kiemelten a nyomtatók festékkazettái) a gépnél nagyobb gyakorisággal cserélődnek, s válhatnak hulladékká. A fő fókusz a számítástechnikai eszközök élettartamának vége, s ebből a szempontból kulcsfogalom a használt személyi számítógép kategória. _____ In their article, the authors discuss the issue of computer waste; under the category of information technology devices they understand the components of computer configurations, that is computers (desktop, portable, terminal etc.) and their peripheries (monitor, printer, CD writer, etc), and also the components and supplements of these (chips, mechanical parts, toner cartridges, etc.). The environmental impact of regular use was examined only from one aspect: during regular use certain components and accessories (especially the toner cartridges of printers) are more often changed and become waste. The main focus is the end of the life time of computer devices, and from this point of view used personal computers are a key concept.

Continuous delivery (CD) is a software engineering approach where the focus lays on creating a short delivery cycle by automating parts of the deployment pipeline which includes build, deploy-, test and release process. CD is based on that during development should be possible to always automatically generate a release based on the source code in its current state. One of CD's many advantages is that through continuous releases it allows you to get a quick feedback loop leading to faster and more efficient implementation of new functions, at the same time fixing errors. Although CD has many advantages, there are also several challenges a maintenance management project must manage in the transition to CD. These challenges may differ depending on the maturity level for a maintenance management project and what strengths and weaknesses the project has. Our research question was: "What challenges can a maintenance management project face in transition to Continuous delivery?" The purpose of this study is to describe Continuous delivery and the challenges a maintenance management project may face during a transition to Continuous delivery. A descriptive case study has been carried out with the data collection methods of interviews and documents. A situation analysis was created based on the collected data in a shape of a process model that represent the maintenance management projects release process. The processmodel was used as the basis of SWOT analysis and analysis by Rehn et al's Maturity Model. From these analyzes we found challenges of a maintenance management project may face in the transition to CD. The challenges are about customers and the management's attitude towards a transition to CD. But the biggest challenge is about automation of the deployment pipeline steps.

We study cooperating distributed systems (CD-systems) of restarting automata that are very restricted: they are deterministic, they cannot rewrite, but only delete symbols, they restart immediately after performing a delete operation, they are stateless, and they have a read/write window of size 1 only, that is, these are stateless deterministic R(1)-automata. We study the expressive power of these systems by relating the class of languages that they accept by mode =1 computations to other well-studied language classes, showing in particular that this class only contains semi-linear languages, and that it includes all rational trace languages. In addition, we investigate the closure and non-closure properties of this class of languages and some of its algorithmic properties.

We study cooperating distributed systems (CD-systems) of stateless deterministic restarting automata with window size 1 that are governed by an external pushdown store. In this way we obtain an automata-theoretical characterization for the class of context-free trace languages.

It is known that cooperating distributed systems (CD-systems) of stateless deterministic restarting automata with window size 1 accept a class of semi-linear languages that properly includes all rational trace languages. Although the component automata of such a CD-system are all deterministic, in general the CD-system itself is not, as in each of its computations, the initial component and the successor components are still chosen nondeterministically. Here we study CD-systems of stateless deterministic restarting automata with window size 1 that are themselves completely deterministic. In fact, we consider two such types of CD-systems, the strictly deterministic systems and the globally deterministic systems.
