Demonstration of antibodies in archival sera from Canadian seals reactive with a European isolate of phocine distemper virus

Sera from seals infected during the 1988 European epizootic of phocine distemper virus and sera from Canadian seals collected since 1972 have been tested for the presence of antibodies to morbillivirus. Approximately one third of the Canadian sera have been shown to contain anti-morbillivirus antibodies; the possibility that these populations of seals provided a source of infection for European seals is discussed.

Personal Seals of Sir Isaac Brock

Two orange coloured seals containing the impression of the personal seal of Sir Isaac Brock. The seal depicts a crest containing a lion in the upper portion and an eagle with its wings spread in the lower portion, which represent strength, clarity of vision and courage. Below the crest is a banner with "Canada" written on it. Above the crest is an Indian on a battlement holding a tomahawk, which represents the alliance Brock had forged with the First Nations. The seals are in a John Sinclair tobacco tin.

The obvious elephant.

Un día, aparece un elefante en las calles de un pueblo, pero nadie ha visto uno antes y no tienen idea de lo que es. Todo el mundo intenta adivinar la identidad y la función de esta extraña bestia. El maquinista del tren lo pone de locomotora, los bomberos lo usan para luchar contra un incendio, el basurero lo emplea para tirar la basura, hasta que Un muchacho descubre cual es la identidad del extraño animal. Para niños hasta ocho años.

The Elephant in the classroom : helping children learn and love Maths.

Jo Boaler ha analizado el progreso del aprendizaje de las matemáticas de miles de alumnos en Estados Unidos y Gran Bretaña, durante su etapa escolar y después en su vida adulta, destacando el impacto que los diferentes métodos de enseñanza pueden tener en una generación entera. Dirigido a profesores, padres y educadores en general, en el libro la autora ofrece diferentes formas de enseñar las matemáticas y de ayudar a los niños en casa a aprender de un modo nuevo y más eficaz, enseñándoles a razonar y a resolver problemas.

Streptococcus halichoeri sp nov., isolated from grey seals (Halichoerus grypus)

Phenotypic and phylogenetic studies were performed on six unidentified, Gram-positive, catalase-negative, chain-forming Streptococcus-like organisms recovered from grey seals. Biochemically the six strains were highly related to each other, but they did not appear to correspond to any recognized species of the genus Streptococcus. Comparative 16S rRNA gene sequencing studies confirmed that phylogenetically the strains were members of the genus Streptococcus, but sequence divergence values of greater than 3 % compared with reference streptococcal species demonstrated that the organisms from seals represent a novel species. SDS-PAGE analysis of whole-cell proteins confirmed the phenotypic distinctiveness of the seal organisms. Based on biochemical criteria and molecular chemical and genetic evidence, it is proposed that the unknown organism from seals be classified as a novel species, Streptococcus halichoeri sp. nov., the type strain of which is CCUG 48324(T) (=CIP 108195(T)).
