Abstract:
The purpose of this study is to explore the performance in Chess and in Mathematics of the college players in Cabanatuan City, Philippines. Specif-ically, it aimed to determine the respondents’ mathematics and chess per-formances, their playing styles and their beliefs regarding chess players and mathematicians. The descriptive correlational research design was utilized in this study and the data gathered by the researcher were tallied and tabulated using frequency, percentage, mean and Pearson’s r. Furthermore, open-ended questions were used to solicit remarks/comments from the respondents regarding the role of chess in enhancing their thinking skills. It was found out that the general weighted average (GWA) in Mathematics of the respondents was above average. Most of them are barangay/school level champions. Males are tactician type of players while females are positional players. A respondent who performed better in higher chess competition also performed better or obtained higher GWA in Mathematics. Furthermore, the respondents believed that a chess player can be a good mathematician especially if they start playing early in life and if chess was a part of the school curriculum since playing chess continuously has helped them in developing and improving their problem solving and critical thinking skills.

Espiral , 2000,
Abstract: Este trabajo presenta un acercamiento a la teoría de los partidos políticos, concentrándose en el análisis de la libertad extra e intrapartidista, la cual insiste en el reconocimiento de una serie de derechos de los partidos en la legislación y de los militantes en los documentos oficiales del partido. Estas variables permiten valorar el caso mexicano frente al primer estatus de libertad, y el caso del Partido de la Revolución democrática frente al segundo estatus, tomado como objeto de estudio de este último por las características de su origen.

Abstract: El chame es una especie con potencial para la acuicultura en Latinoamérica. Sin embargo, su producción depende de la utilización de individuos juveniles capturados en el medio silvestre, siendo necesaria la reproducción en cautiverio. Objetivo: determinar las condiciones ideales para la obtención de gametos viables y larvas en laboratorio. Métodos: un total de 16 machos y 16 hembras adultos se asignaron a cuatro grupos (n=4) y fueron inyectados con solución salina, Desgly10-Ala6 LHRHa, GnRHa de salmón+domperidone, o con implantes de GnRHa de salmón. Resultados: se logró exitosamente la liberación de esperma para todos los tratamientos. La inducción al desove fue del 100% a las 24 y 48 h para el grupo implantado con GnRHa, 25% para el grupo con LHRHa, y 0% para el grupo GnRHa de salmón+domperidone (48-72 h post-inyección). Conclusiones: el uso de GnRHa y LHRHa es una herramienta útil en la reproducción inducida del chame. Se incluye una descripción morfológica de los oocitos, calidad de esperma y primeros estadio del desarrollo larvario. Se discuten también las condiciones óptimas de salinidad para la fertilización e incubación de huevos fertilizados. O chame é uma espécie com potencial para a aquicultura na América Latina. Porém, toda a produ o depende da captura de juvenis selvagens. Objetivo: determinar as condi es ideais para a obten o de gametas viáveis e larvas no laboratório. Métodos: um total de 16 machos e 16 fêmeas adultos foram divididos em quatro grupos (n=4) e foram tratados com inje o de Desgly10Ala6, LHRHa, GnRHa de Salmon+domperidone ou implante de GnRHa de salm o. Resultados: foi possível induzir exitosamente a libera o de esperma com todos os tratamentos. A indu o de desove foi do 100% às 24 e 48 h para o grupo implantado com GnRHa, 25% para o tratamento com LHRHa e 0% para o grupo injetado com GnRHa de Salmon+domperidone (48-72 h após-inje o). Conclus es: o uso de GnRHa e LHRHa é uma ferramenta útil na reprodu o induzida do chame. Neste trabalho está incluída a descri o dos oócitos, qualidade do esperma e dos estágios iniciais de desenvolvimento larval. Também s o abordados os valores ótimos de salinidade, tanto para a fertiliza o como para a incuba o dos ovos fertilizados. The Pacific fat sleeper is a potential species for aquaculture in Latin American countries. Nevertheless, production depends on wildcaught juveniles, thus needing hatchery produced larvae. Objective: the purpose of this study was to determine the ideal conditions for viable gamete release and larvae laboratory production. Methods: a total of 16 mature mal

Abstract: Many mycobacterial genomes contained two phylogenetically distinct active rhomboids orthologous to Rv0110 (rhomboid protease 1) and Rv1337 (rhomboid protease 2) of Mycobacterium tuberculosis H37Rv, which were acquired independently. There was a genome-wide conservation and organization of the orthologs of Rv1337 arranged in proximity with glutamate racemase (mur1), while the orthologs of Rv0110 appeared evolutionary unstable and were lost in Mycobacterium leprae and the Mycobacterium avium complex. The orthologs of Rv0110 clustered with eukaryotic rhomboids and contained eukaryotic motifs, suggesting a possible common lineage. A novel nonsense mutation at the Trp73 codon split the rhomboid of Mycobacterium avium subsp. Paratuberculosis into two hypothetical proteins (MAP2425c and MAP2426c) that are identical to MAV_1554 of Mycobacterium avium. Mycobacterial rhomboids contain putative rhomboid catalytic signatures, with the protease active site stabilized by Phenylalanine. The topology and transmembrane helices of the Rv0110 orthologs were similar to those of eukaryotic secretase rhomboids, while those of Rv1337 orthologs were unique. Transcription assays indicated that both mycobacterial rhomboids are possibly expressed.Mycobacterial rhomboids are active rhomboid proteases with different evolutionary history. The Rv0110 (rhomboid protease 1) orthologs represent prokaryotic rhomboids whose progenitor may be the ancestors of eukaryotic rhomboids. The Rv1337 (rhomboid protease 2) orthologs appear more stable and are conserved nearly in all mycobacteria, possibly alluding to their importance in mycobacteria. MAP2425c and MAP2426c provide the first evidence for a split homologous rhomboid, contrasting whole orthologs of genetically related species. Although valuable insights to the roles of rhomboids are provided, the data herein only lays a foundation for future investigations for the roles of rhomboids in mycobacteria.The genus Mycobacterium consists of ~148 species [1
