INFO2009 2012-13 Resource Group 27 & 31: The public awareness of science

Resources for coursework 2 of INFO 2009. A video made to promote the public awareness of science as a topic. It goes through interesting facts and explains what you can do to make a difference. A flyer made to advertise the video, explaining what it is and how it can be used.

Promoting effective group work in the primary classroom : a handbook for teachers and practitioners.

Recurso que muestra a los profesores cómo crear un aula comprensiva y solidaria mediante el desarrollo de habilidades sociales, comunicativas y de trabajo de todos los alumnos. Anima a los niños y a sus maestros a desarrollar relaciones de apoyo para facilitar el rendimiento académico, el comportamiento social positivo y la motivación. También da consejos prácticos para la creación y funcionamiento de grupos de trabajo eficaces. El manual se compone de dos partes; la primera proporciona recomendaciones e información acerca de cómo pueden ser utilizados correctamente, y aplicados en las aulas de la escuela primaria, los grupos de trabajo; la segunda proporciona ejemplos de un programa de desarrollo de las actividades. Estas actividades están organizadas en una secuencia que pretende construir habilidades de trabajo de grupo, donde los niños pasan más tiempo en la tarea y son menos dependientes del profesor.

Sexual System, Sex Ratio, and Group Living in the Shrimp Thor amboinensis (De Man): Relevance to Resource-Monopolization and Sex-Allocation Theories

The sexual system of the symbiotic shrimp Thor amboinensis is described, along with observations on sex ratio and host-use pattern of different populations. We used a comprehensive approach to elucidate the previously unknown sexual system of this shrimp. Dissections, scanning electron microscopy, size-frequency distribution analysis, and laboratory observations demonstrated that T amboinensis is a protandric hermaphrodite: shrimp first mature as males and change into females later in life. Thor amboinensis inhabited the large and structurally heterogeneous sea anemone Stichoclactyla helianthus in large groups (up to 11 individuals) more frequently than expected by chance alone. Groups exhibited no particularly complex social structure and showed male-biased sex ratios more frequently than expected by chance alone. The adult sex ratio was male-biased in the four separate populations studied, one of them being thousands of kilometers apart from the others. This study supports predictions central to theories of resource monopolization and sex allocation. Dissections demonstrated that unusually large males were parasitized by an undescribed species of isopod (family Entoniscidae). Infestation rates were similarly low in both sexes (approximate to 11%-12%). The available information suggests that T. amboinensis uses pure search promiscuity as a mating system. This hypothesis needs to be formally tested with mating behavior observations and field measurements on the movement pattern of both sexes of the species. Further detailed studies on the lifestyle and sexual system of all the species within this genus and the development of a molecular phylogeny are necessary to elucidate the evolutionary history of gender expression in the genus Thor.

Integral group ring of the Suzuki sporadic simple group

Using the Luthar-Passi method, we investigate the classical Zassenhaus conjecture for the normalized unit group of the integral group ring of the Suzuki sporadic simple group Suz. As a consequence, for this group we confirm the Kimmerle`s conjecture on prime graphs.

A group topology on the free abelian group of cardinality c that makes its square countably compact

Under p = c, we prove that it is possible to endow the free abelian group of cardinality c with a group topology that makes its square countably compact. This answers a question posed by Madariaga-Garcia and Tomita and by Tkachenko. We also prove that there exists a Wallace semigroup (i.e., a countably compact both-sided cancellative topological semigroup which is not a topological group) whose square is countably compact. This answers a question posed by Grant.

Effects of hydroxyl group distribution on the reactivity, stability and optical properties of fullerenols

We investigate the impact of hydroxyl groups on the properties of C(60)(OH)(n) systems, with n = 1, 2, 3, 4, 8, 10, 16, 18, 24, 32 and 36 by means of first-principles density functional theory calculations. A detailed analysis from the local density of states has shown that adsorbed OH groups can induce dangling bonds in specific carbon atoms around the adsorption site. This increases the tendency to form polyhydroxylated fullerenes (fullerenols). The structural stability is analyzed in terms of the calculated formation enthalpy of each species. Also, a careful examination of the electron density of states for different fullerenols shows the possibility of synthesizing single molecules with tunable optical properties.

About the Use of the HdHr Algorithm Group in Integrating the Movement Equation with Nonlinear Terms

This work summarizes the HdHr group of Hermitian integration algorithms for dynamic structural analysis applications. It proposes a procedure for their use when nonlinear terms are present in the equilibrium equation. The simple pendulum problem is solved as a first example and the numerical results are discussed. Directions to be pursued in future research are also mentioned. Copyright (C) 2009 H.M. Bottura and A. C. Rigitano.

Highly polymorphic in silico-derived microsatellite loci in the potato-infecting fungal pathogen Rhizoctonia solani anastomosis group 3 from the Colombian Andes

Fourteen polymorphic microsatellite DNA markers derived from the draft genome sequence of Rhizoctonia solani anastomosis group 3 (AG-3), strain Rhs 1AP, were designed and characterized from the potato-infecting soil fungus R. solani AG-3. All loci were polymorphic in two field populations collected from Solanum tuberosum and S. phureja in the Colombian Andes. The total number of alleles per locus ranged from two to seven, while gene diversity (expected heterozygosity) varied from 0.11 to 0.81. Considering the variable levels of genetic diversity observed, these markers should be useful for population genetic analyses of this important dikaryotic fungal pathogen on a global scale.

Hospital de Caridade São Pedro de Alcântara: assistência e saúde em Goiás ao longo do século XIX

Este artigo apresenta aspectos da trajetória do Hospital de Caridade São Pedro de Alcântara, na cidade de Goiás, ao longo do século XIX. Instituição leiga fundada no ano de 1825, o hospital nasceu da iniciativa de um grupo local influente que reconheceu um mal social: a ausência de assistência aos destituídos e enfermos. No que se referia à assistência social, ele abarcava funções e princípios caritativos cristãos, assistindo alienados, internados em cárceres, doentes e necessitados em geral, e, com a inauguração do cemitério público, sepultava gratuitamente os indigentes.
