On the problem of cognition of mineralogy and geochemistry of the landscape of mining territories

A methodology for studying the forms of finding chemical elements in the landscape of mining territories is given. The necessity of mineralogical and geochemical integration of methods is shown, the influence of the forms of occurrence of chemical elements in the landscape on the extent of their absorption by biota, in particular, the coefficient of biological absorption. The dependence of the forecast of the state of mining geosystems on the forms of presence of potentially hazardous chemical elements in them is determined.

How Old is the Hebrew Bible? A Response to Konrad Schmid

The methodological issues about how to integrate the linguistic history of Hebrew into our inquiries into the literary history of the Bible are complicated and controverted. In this contribution to the discussion, I attempt to clarify areas of agreement and disagreement, provide an example (Genesis 1–11) where some of the issues of integration of methods can be tested, and consider the relevant evidence for the emulation of classical Hebrew.

The effect of balanced and unbalanced soccer small-sided games on the rating of perceived exertion in youth players (El efecto de los partidos reducidos de fútbol equilibrados y desequilibrados em la calificación del esfuerzo percebido em los jugadores j

The integration of methods to quantify the physical demands [e.g., Rating Perceived Exertion (RPE)] in small-sided games (SSGs) in younger soccer players, has been scarcely studied. In addition, few studies have been addressing the impact of balanced vs. unbalanced SSGs, in particular in youth players’ RPE. This study aimed to investigate differences between balanced and unbalanced format games in young soccer players’ RPE, controlling for different playing field sizes. The sample comprised 10 field players and 2 goalkeepers (Gk) being 13,55±0,51 years-old. The players performed 6 randomized different situations, following an identical methodology across the training days: (1) 4Vs.4+Gk (2) 4Vs.5+Gk, and (3) 4Vs.6+Gk. All situations were performed in 30x25m and 40x30m. The game situations lasted 5 minutes of practice and another 5 minutes of rest. After the execution of all game situations, participants were asked individually about their self-perceived effort, using the OMNI effort scale. In unbalanced format games when the difference in the number of players increases, RPE is lower. This tendency seems to be more evident in smaller compared to bigger playing field areas. The difference in RPE scores considering different dimensions of playing space seems not to be linear. Balanced soccer SSGs promote higher RPE than unbalanced soccer SSG. More studies on the topic are required considering different playing field areas as well as different players' backgrounds. Resumen. La integración de métodos para cuantificar las demandas físicas [por ejemplo, Calificación del Esfuerzo Percibido (CEP)] en juegos reducidos (JR) en jugadores de fútbol más jóvenes, ha sido poco estudiada. Además, pocos estudios han abordado el impacto de los JR equilibrados frente a los no equilibrados, en particular en el CEP de los jugadores juveniles. Este estudio tuvo como objetivo investigar las diferencias entre los juegos de formato equilibrado y desequilibrado en el CEP de los jugadores de fútbol jóvenes, controlando los diferentes tamaños del campo de juego. La muestra estuvo compuesta por 10 jugadores de campo y 2 porteros (P) con 13,55 ± 0,51 años. Los jugadores realizaron 6 situaciones diferentes aleatorias, siguiendo una metodología idéntica a lo largo de los días de entrenamiento: (1) 4Vs.4 + P (2) 4Vs.5 + P, y (3) 4Vs.6 + P. Todas las situaciones se realizaron en 30x25m y 40x30m. Las situaciones de juego duraron 5 minutos de práctica y otros 5 minutos de descanso. Después de la ejecución de todas las situaciones del juego, se preguntó a los participantes individualmente sobre su esfuerzo autopercibido, utilizando la escala de esfuerzo OMNI. En los juegos de formato desequilibrado, cuando aumenta la diferencia en el número de jugadores, el CEP es menor. Esta tendencia parece ser más evidente en las áreas de juego más pequeñas que en las más grandes. La diferencia en las puntuaciones de CEP considerando las diferentes dimensiones del espacio de juego parece no ser lineal. Los JR de fútbol equilibrado promueven un CEP más alto que el JR de fútbol desequilibrado. Se requieren más estudios sobre el tema considerando las diferentes áreas del campo de juego, así como los antecedentes de los diferentes jugadores.

Methods, tools, and techniques in toxicovigilance

Toxicovigilance is the active process of identifying and evaluating the toxic risks existing in a community, and evaluating the measures taken to reduce or eliminate them. The operation of toxicovigilance requires the use of methods, tools, and techniques. The objective of this article is to describe the organization of toxicovigilance, to identify their components, and to specify the methods, tools and techniques which are applied to them and are necessary for their operation. To achieve those goals, we based our study on a bibliographic synthesis, where some key references were selected, analysed, and summarised. The results of our study have shown that the performance of a toxicovigilance system requires the mastery and integration of methods, tools, and techniques by trained and experienced staff. Those methods, tools and techniques can be classified into six stages. The study also showed that the practice of toxicovigilance is one of the core tasks of a poison control centres. Our study has shown that Anti-poison and Pharmacovigilance center Morocco constitutes a real observatory in terms of toxicovigilance. It ensures a vigilance and alert function concerning different toxic groups.

A Software Ecosystem platform for the development of Recommender Systems

Many application domains need to recommend resources for users. The development of solutions focused on the reuse of Recommender System components creates an interesting scenario from a Software Ecosystem perspective. Besides the interaction between actors and technology, a Software Ecosystem for the development of Recommender Systems should allow for integration with systems and platforms that support other ecosystems. The problem addressed by this study is the integration of methods, techniques, and approaches of existing Recommender Systems in a systematic way, facilitating the implementation of new solutions, their reuse and sharing, and the collaboration among the actors involved. This study, therefore, aims to propose R.ECOS, a Software Ecosystem platform to support the development and management of Recommender Systems, allowing for integration between multiple applications and other Software Ecosystems. The evaluation was conducted in two stages. First, two feasibility studies were carried out to validate both technology and architecture. Later, two case studies were conducted in real-world contexts. The results point to the viability of the proposal.
