Spider diversity (Arachnida: Araneae) in Atlantic Forest areas at Pedra Branca State Park, Rio de Janeiro, Brazil

BACKGROUND: There has never been any published work about the diversity of spiders in the city of Rio de Janeiro using analytical tools to measure diversity. The only available records for spider communities in nearby areas indicate 308 species in the National Park of Tijuca and 159 species in Marapendi Municipal Park. These numbers are based on a rapid survey and on an one-year survey respectively. NEW INFORMATION: This study provides a more thorough understanding of how the spider species are distributed at Pedra Branca State Park. We report a total of 14,626 spider specimens recorded from this park, representing 49 families and 373 species or morphospecies, including at least 73 undescribed species. Also, the distribution range of 45 species was expanded, and species accumulation curves estimate that there is a minimum of 388 (Bootstrap) and a maximum of 468 species (Jackknife2) for the sampled areas. These estimates indicates that the spider diversity may be higher than observed.Fil: Castanheira, Pedro. Universidade Federal do Rio de Janeiro; BrasilFil: Pérez González, Abel.

Units of work within vulnerable socioeducative settings: a practical approach

This Master's Thesis presents a Teaching Unit proposal for the subject of English, which is developed in the second year of Compulsory Secondary Education around a vulnerable socio-educative setting. The work is structured in two parts. The first one is devoted to the theoretical basis, taking into account the European determinations regarding language teaching, the theories of second language acquisition and the communicative approach. The second part deals with the methodological aspects, as well as the temporal and normative features that frame the Teaching Unit, together with the explanation of both the sessions and the activities. Finally, a series of final inferences are made, emphasizing the relevance of English language teaching within vulnerable socio-educative environments through the elaboration of communicative tasks that prioritize the development of communicative skills in a foreign language.En este Trabajo de Fin de Máster se presenta la realización de una propuesta de Unidad Didáctica para la enseñanza del Inglés, desarrollada en un curso de 2º de la ESO y en un contexto socioeducativo vulnerable. El trabajo se estructura en dos partes. La primera está dedicada a la fundamentación teórica, teniendo en cuenta las determinaciones europeas sobre la enseñanza de idiomas, las teorías de adquisición de segundas lenguas y el enfoque comunicativo. La segunda parte aborda los aspectos metodológicos, así como las características temporales y legislativas que enmarcan la Unidad Didáctica, junto con la explicación de las sesiones y las actividades pertinentes. Por último, se realizan una serie de consideraciones finales, destacando especialmente la enseñanza de la lengua inglesa en contextos socioeducativos vulnerables a través de la elaboración de tareas comunicativas que priorizan el desarrollo de las habilidades comunicativas en lengua extranjera.Departamento de Didáctica de la Lengua y LiteraturaMáster en Profesor de Educación Secundaria Obligatoria y Bachillerato, Formación Profesional y Enseñanzas de Idioma

Crónicas sobre el desastre en Río de Janeiro

La noche del 2 de septiembre de 2018 se inició un trágico incendio que destruyó el histórico edificio que ocupaba el Museo Nacional de Río de Janeiro (MNRJ), nada menos que el palacio São Cristóvão que fuera la antigua morada de la familia imperial brasileña localizada en la Quinta da Boa Vista en pleno corazón de la metrópoli carioca. En lo que fue tal vez la mayor pérdida de patrimonio científico de los últimos 50 años, el fuego se llevó consigo una enorme cantidad de especímenes representativos de la biodiversidad de Brasil y resto de Latinoamérica junto con artefactos culturales calculado en unos 20 millones de piezas. Este incendio consumó la pesadilla que pervive en la intimidad de todas las instituciones que actúan como repositorio, vale decir: la perdida en apenas unas horas de todo el trabajo y la información de muchas décadas fruto del trabajo de varias generaciones de científicos.Fil: Mulieri, Pablo Ricardo.

Independent transversal total domination versus total domination in trees

A subset of vertices in a graph G is a total dominating set if every vertex in G is adjacent to at least one vertex in this subset. The total domination number of G is the minimum cardinality of any total dominating set in G and is denoted by gamma(t)(G). A total dominating set of G having nonempty intersection with all the independent sets of maximum cardinality in G is an independent transversal total dominating set. The minimum cardinality of any independent transversal total dominating set is denoted by gamma(u) (G). Based on the fact that for any tree T, gamma(t) (T) <= gamma(u) (T) <= gamma(t) (T) + 1, in this work we give several relationship(s) between gamma(u) (T) and gamma(t) (T) for trees T which are leading to classify the trees which are satisfying the equality in these bound

Roman domination in direct product graphs and rooted product graphs1

Let G be a graph with vertex set V(G). A function f : V(G) -> {0, 1, 2) is a Roman dominating function on G if every vertex v is an element of V(G) for which f(v) = 0 is adjacent to at least one vertex u is an element of V(G) such that f(u) = 2. The Roman domination number of G is the minimum weight omega(f) = Sigma(x is an element of V(G)) f(x) among all Roman dominating functions f on G. In this article we study the Roman domination number of direct product graphs and rooted product graphs. Specifically, we give several tight lower and upper bounds for the Roman domination number of direct product graphs involving some parameters of the factors, which include the domination, (total) Roman domination, and packing numbers among others. On the other hand, we prove that the Roman domination number of rooted product graphs can attain only three possible values, which depend on the order, the domination number, and the Roman domination number of the factors in the product. In addition, theoretical characterizations of the classes of rooted product graphs achieving each of these three possible values are given.The second author (Iztok Peterin) has been partially supported by the Slovenian Research Agency by the projects No. J1-1693 and J1-9109.

A constructive characterization of vertex cover Roman trees

A Roman dominating function on a graph G = (V (G), E (G)) is a function f : V (G) -> {0, 1, 2} satisfying the condition that every vertex u for which f (u) = 0 is adjacent to at least one vertex v for which f (v) = 2. The Roman dominating function f is an outer-independent Roman dominating function on G if the set of vertices labeled with zero under f is an independent set. The outer-independent Roman domination number gamma(oiR) (G) is the minimum weight w(f ) = Sigma(v is an element of V), ((G)) f(v) of any outer-independent Roman dominating function f of G. A vertex cover of a graph G is a set of vertices that covers all the edges of G. The minimum cardinality of a vertex cover is denoted by alpha(G). A graph G is a vertex cover Roman graph if gamma(oiR) (G) = 2 alpha(G). A constructive characterization of the vertex cover Roman trees is given in this article

Relating the Outer-Independent Total Roman Domination Number with Some Classical Parameters of Graphs

For a given graph G without isolated vertex we consider a function f : V (G) -> {0,1, 2}. For every i is an element of {0,1, 2}, let V-i = {v is an element of V (G) : f (v) = i}. The function f is known to be an outer-independent total Roman dominating function for the graph G if it is satisfied that; (i) every vertex in V-0 is adjacent to at least one vertex in V-2; (ii) V-0 is an independent set; and (iii) the subgraph induced by V-1 boolean OR V-2 has no isolated vertex. The minimum possible weight omega(f) = Sigma(v is an element of V(G)) f(v) among all outer-independent total Roman dominating functions for G is called the outer-independent total Roman domination number of G. In this article we obtain new tight bounds for this parameter that improve some well-known results. Such bounds can also be seen as relationships between this parameter and several other classical parameters in graph theory like the domination, total domination, Roman domination, independence, and vertex cover numbers. In addition, we compute the outer-independent total Roman domination number of Sierpinski graphs, circulant graphs, and the Cartesian and direct products of complete graphs

Levels of heavy metals composition in atmospheric aerosol samples and the influence of african episodes

Particulate matter pollution is a serious environmental issue mainly due to the presence of toxic substances and trace metals in the atmosphere from a variety of pollution emission sources. Information about aerosol composition and their sources especially during pollution events can be further used to establish strategies for the reduction of particulate matter concentration. The objective in the present study was to analyse variations in total suspended particle (TSP) mass concentration and heavy metal components for evaluating the atmospheric loadings of substances with different sources as well as to further examine the relationship between the occurrence of African dust intrusions and metallic species concentrations at our coastal station located in South Spain. Non-destructive Wavelength-Dispersive X-Ray Fluorescence (WDXRF) analysis has been applied for the determination of multi-element contents of atmospheric particulate matter.Universidad de Málaga.
