Defence chemistry modulation by light and temperature (results in 4 excel files, zipped)

The goals of this study were (1) to investigate whether Fucus vesiculosus regulates the production of its antifouling defence chemicals against microfoulers in response to light limitation and temperature shifts and (2) to investigate if different surface concentrations of defence compounds shape epibacterial communities. F. vesiculosus was incubated in indoor mesocosms at five different temperature conditions (5 to 25°C) and in outdoor mesocosms under six differently reduced sunlight conditions (0 to 100%), respectively. Algal surface concentrations of previously identified antifouling compounds - dimethylsulphopropionate (DMSP), fucoxanthin and proline - were determined and the bacterial community composition was characterized by in-depth sequencing of the 16S-rRNA gene. Altogether, the effect of different treatment levels upon defence compound concentrations was limited. Under all conditions DMSP alone appeared to be sufficiently concentrated to warrant for at least a partial inhibitory action against epibiotic bacteria of F. vesiculosus. In contrast, proline and fucoxanthin rarely reached the necessary concentration ranges for self-contained inhibition. Nonetheless, in both experiments along with the direct influence of temperature and light, all three compounds apparently affected (and thereby shaped) the overall bacterial community composition associated with F. vesiculosus since tendencies for insensitivity towards all three compounds were observed among bacterial taxa that typically dominate those communities. Given that the concentrations of at least one of the compounds (in most cases DMSP) were always high enough to inhibit bacterial settlement, we conclude that the capacity of F. vesiculosus for such defence will hardly be compromised by shading or warming to temperatures up to 25°C.

Unity assessment: desarrollo de un plugin de Unity evaluación basada en juegos y desarrollo de un juego de artes escénicas

En el ámbito educativo, gran parte de los docentes realizan la evaluación de alumnos mediante herramientas tradicionales: exámenes, cuestionario, trabajos, etc. Esta forma de evaluar presenta inconvenientes, por un lado, precisa que el profesor esté durante todo el proceso de evaluación y, por otro lado, exige tiempo y trabajo desmesurado. Por ello, en este proyecto nos dedicamos a crear una forma de evaluar diferente. Esta forma de evaluar consistirá, por un lado, en obtener información cuantitativa sobre cuánto ha aprendido el alumno a través de una puntuación. Este tipo de evaluación, se realizará mediante un videojuego. Por otro lado, consistirá en almacenar esta puntuación en algún sitio de acceso fácil y rápido para el profesor. Para este cometido hemos elegido una plataforma virtual, Moodle. Elegimos Moodle porque es una plataforma diseñada para ayudar a los profesores en su labor. Pueden gestionar sus asignaturas e interactuar con sus alumnos. El profesor crea un entorno centrado en el alumno que le ayuda a cimentar conocimientos según sus habilidades. Hemos elegido los videojuegos porque son una herramienta de enseñanza efectiva. Ofrecen una gran mejora en el rendimiento académico del alumno, así como potenciar la adquisición de conocimientos o incluso aumentar la motivación y el interés del jugador sobre el contenido del videojuego. Por tanto, en este proyecto también nos centraremos en crear un videojuego. Crearemos un videojuego orientado al teatro para fomentar el interés y la motivación de los jugadores en este campo. El videojuego estará basado en la obra de teatro llamada El Alcalde de Zalamea del autor Calderón de la Barca. Por último, para enviar la puntuación obtenida a Moodle desde el videojuego es necesario crear una comunicación entre estas dos tecnologías. Nuestro objetivo primordial en este proyecto es crear dos aplicaciones. Una en el videojuego que es la encargada de enviar la puntuación. Y otra en Moodle, encargada de almacenar la puntuación en la base de datos y mostrarla al profesor, de una forma intuitiva.

Is the date of birth an advantage/ally to excel in handball?

The Relative Age Effect (RAE) has been analyzed in a population of Spanish international handball players (n=161) divided into four different levels: Senior, Junior, Juvenile and Promising Talents. The variables registered were quarter, half year and year of birth using the initial information of their date of birth. The data were collected from the Royal Spanish Handball Federation on-line data base. The statistical method used was the χ2 and the minimum level of significance was set at p<0.05. The total results on distribution by quarter show a significant difference (χ2= 21.68; p<0.01) with a greater frequency of players born in the first quarter (40.37%) compared to those born in the second (22.36%), third (16.15%) and fourth quarter (21.12%). The total results on the distribution of birth date by half year show a significant difference (χ2= 10.44; p<0.01) with a greater frequency of players born in the first half of the year (62.73%). With regard to the rate of births registered in an even numbered or odd numbered year there are significant differences when the rates for an even numbered year (64.60%) and an odd numbered year (35.40%) are compared with those of the general population (χ2= 13.72; p<0.001). Based on the data collected and analyzed it can be concluded that there is a RAE in the basic categories of the Spanish national men’s handball teams according to quarter, half year and year of birth (even or odd numbered), but there exists little knowledge about the causes and consequence which may be produced by, or derive from, this effect.

Estimation of pharmacokinetic parameters from non-compartmental variables using Microsoft Excel((R))

This study was conducted to develop a method, termed 'back analysis (BA)', for converting non-compartmental variables to compartment model dependent pharmacokinetic parameters for both one- and two-compartment models. A Microsoft Excel((R)) spreadsheet was implemented with the use of Solver((R)) and visual basic functions. The performance of the BA method in estimating pharmacokinetic parameter values was evaluated by comparing the parameter values obtained to a standard modelling software program, NONMEM, using simulated data. The results show that the BA method was reasonably precise and provided low bias in estimating fixed and random effect parameters for both one- and two-compartment models. The pharmacokinetic parameters estimated from the BA method were similar to those of NONMEM estimation.

Characterization of the defined MDC types and compilation of MDC initiation times (excel-file 19 kB)

Mud accumulates on continental shelves under a variety of environmental conditions and results in a diverse formation of mud depocenters (MDCs). Their three-dimensional architectures have been in the focus of several recent studies. Due to some terminological confusion concerning MDCs, the present study sets out to define eight individual MDC types in terms of surface sediment distribution and internal geometry. Under conditions of substantial sediment supply, prodeltas (distal zones off river deltas; triangular sheets), subaqueous deltas (disconnected from deltas by strong normal-to-shore currents; wedge-like clinoforms), and mud patches (scattered distribution) and mud blankets (widespread covers) are formed. Forced by hydrodynamic conditions, mud belts in the strict sense (detached from source; elongated bodies), and shallow-water contourite drifts (detached from source; growing normal to prevailing current direction; triangular clinoforms) develop. Controlled by local morphology, mud entrapments (in depressions, behind morphological steps) and mud wedges (triangular clinoforms growing in flow direction) are deposited. Shelf mud deposition took place (1) during early outer-shelf drowning (~14 ka), (2) after inner-shelf inundation to maximum flooding (9.5-6.5 ka), and (3) in sub-recent times (<2 ka). Subsequent expansion may be (1) concentric, in cases where the depocenter formed near the fluvial source, (2) uni-directional, extending along advective current transport paths, and (3) progradational, forming clinoforms that grow either parallel or normal to the bottom current direction. Classical mud belts may be initiated around defined nuclei, the remote sites of which are determined by seafloor morphology rather than the location of the source. From a stratigraphic perspective, mud depocenters coincide with sea-level highstand-related, shelf-wide condensed sections. They often show a conformable succession from transgressive to highstand systems tract stages.

THE MICROSTRUCTURES OF ZR-EXCEL ALLOY: EFFECTS OF HEAVY ION IRRADIATION, PLASTIC DEFORMATION, THERMAL TREATMENT AND IN-SITU HEATING

Zr-Excel alloy (Zr-3.5Sn-0.8Nb-0.8Mo) is a dual phase (α + β) alloy in the as-received pressure tube condition. It has been proposed to be the pressure tube candidate material for the Generation-IV CANDU-Supercritical Water Reactor (CANDU-SCWR). In this dissertation, the effects of heavy ion irradiation, deformation and heat treatment on the microstructures of the alloy were investigated to enable us to have a better understanding of the potential in-reactor performance of this alloy. In-situ heavy ion (1 MeV) irradiation was performed to study the nucleation and evolution of dislocation loops in both α- and β-Zr. Small and dense type dislocation loops form under irradiation between 80 and 450 °C. The number density tends to saturate at ~ 0.1 dpa. Compared with the α-Zr, the defect yield is much lower in β-Zr. The stabilities of the metastable phases (β-Zr and ω-Zr) and the thermal-dynamically equilibrium phase, fcc Zr(Mo, Nb)2, under irradiation were also studied at different temperatures. Chemi-STEM elemental mapping was carried out to study the elemental redistribution caused by irradiation. The stability of these phases and the elemental redistribution are strongly dependent on irradiation temperature. In-situ time-of-flight neutron diffraction tensile and compressive tests were carried out at different temperatures to monitor lattice strain evolutions of individual grain families during these tests. The β-Zr is the strengthening phase in this alloy in the as-received plate material. Load is transferred to the β-Zr after yielding of the α-Zr grains. The temperature dependence of static strain aging and the yielding sequence of the individual grain families were discussed. Strong tensile/compressive asymmetry was observed in the {0002} grain family at room temperature. The microstructures of the sample deformed at 400 °C and the samples only subjected to heat treatment at the same temperature were characterized with TEM. Concentration of β phase stabilizers in the β grain and the morphology of β grain have significant effect on the stability of β- and ω-Zr under thermal treatment. Applied stress/strain enhances the decomposition of isothermal ω phase but suppresses α precipitation inside the β grains at high temperature. An α → ω/ZrO phase transformation was observed in the thin foils of Zr-Excel alloy and pure Zr during in-situ heating at 700 °C in TEM.

Three-capital approach to the study of young people who excel in vocational occupations: A case of WorldSkills competitors and entrepreneurship

This paper examines the entrepreneurial inclinations of young people who achieved excellence in vocational occupations. We propose a three-capital approach to the study of entrepreneurship. Relying on the existing theories and original qualitative and quantitative data analyses, findings from interviews with 30 entrepreneurial and 10 non-entrepreneurial WorldSkills competitors show that psychological capital, social capital and human capital can be combined to explore how young people who excel in vocational occupations develop entrepreneurial mindsets. We show that training for and participation in the largest vocational skills event globally - WorldSkills competition - develops selected aspects of three capitals. However, we also discover that the entrepreneurial motivation precedes competitors' involvement with WorldSkills. (DIPF/Orig.)

Documentos interactivos EXCEL para simuladores

La tecnología conocida como Microsoft Visual Studio Tools for Office (VSTO) ofrece la posibilidad de integrar Office con la plataforma .NET de forma que podamos implementar aplicaciones .NET con la apariencia de documentos de Microsoft Office. La utilización de la tecnología VSTO con hojas de cálculo para la creación de herramientas de simulación es un campo interesante por la familiaridad que las hojas de cálculo ofrecen a cualquier usuario. Cuando se desarrolla un complemento para un simulador, dicho complemento suele ser muy específico de un simulador concreto, por lo que los elementos desarrollados en estos proyectos no es posible reutilizarlos con otro simulador. Esta es la motivación que lleva a crear este proyecto: facilitar la creación de extensiones para Excel adaptables a distintos tipos de simulador, de manera que sea posible reutilizar las extensiones y sus elementos constituyentes.Para eso, se ha desarrollado un framework para la creación de extensiones Excel con VSTO que puedan ser fácilmente adaptables a diferentes tipos de simuladores. Los principales puntos que toca este framework son: - Elementos comunes a todo proyecto de simuladores. Se han ofrecido precargados un conjunto de elementos que son comunes en el desarrollo de estas aplicaciones, de manera que no sea necesario tener que implementarlos. - Definición de elementos de simulación, lo que se ha denominado en el framework controles. Se ha buscado reducir el coste de desarrollo y maximizar la reutilización. - Comunicación con los simuladores. Se ha definido e implementado una interfaz que permite la comunicación de las hojas Excel con los posibles motores de simulación. Se ha ofrecido esta interfaz en la interfaz ISimulatorService y se ha ofrecido también un cliente para comunicar con los simuladores de esta interfaz.
