El comercio internacional en el Caribe y su transporte por vía marítima

Para los países del Caribe, el comercio internacional de bienes y su transporte son más relevantes que para muchos otros en la región (véase Boletín FAL No. 136http://www.eclac.cl/transporte/noticias/bolfall/3/4993/fal136~1.htm) y la subregión está fuertemente afectada por los cambios estructurales en el transporte marítimo (véase Boletín FAL No. 142http://www.eclac.cl/transporte/noticias/bolfall/0/5000/fal142.htm).Para analizar estos temas, la Unidad de Transporte y la subsede de la CEPAL (Trinidad y Tobago), organizaron conjuntamente una Reunión de Expertos, que tuvo lugar en Puerto España, Trinidad y Tobago, entre el 14 y el 15 de septiembre de 2000. Participaron 26 representantes de diferentes instituciones y organizaciones académicas, intergubernamentales, financieras, y empresariales.La presente edición del Boletín FAL informa sobre algunos de los resultados de esa reunión. El informe completo de la reunión se publicó bajo la sigla ECLAC LC/CAR/G.621; para solicitarlo en formato electrónico o impreso, sírvase contactar a Lance Busby,LBusby@ECLACPOS.org.

Impactos da ocupação urbana e qualidade das águas superficiais na microbacia da Va-de-Cães (Belém/PA)

A microbacia hidrográfica de Val-de-Cães, com 10,10Km², situada na porção norte do Município de Belém, apresenta como característica a densa ocupação urbana, representada por ocupações clandestinas, conjuntos residenciais e por áreas institucionais. O presente estudo analisa os impactos provenientes pelas principais formas de ocupação e uso da microbacia de Val-de-Cães, utilizando como indicador a qualidade das águas superficiais do corpo hídrico. As análises das águas foram realizadas em dois períodos, um chuvoso (fevereiro) e outro seco (agosto), sendo determinados os seguintes parâmetros: turbidez, condutividade, cor, pH, Oxigênio Dissolvido, temperatura, componentes nitrogenados, Demanda Bioquímica de Oxigênio, metais, óleos e graxas e coliformes totais e fecais. A água do igarapé revelou valores elevados na jusante do igarapé, possivelmente pela influência direta da baia do Guajará, para o pH, óleos e graxas, coliformes e Demanda Bioquímica de Oxigênio. Na nascente os parâmetros de coliformes totais e Demanda Bioquímica de Oxigênio apresentam valores que são considerados elevados em relação aos demais pontos de coleta, mas é o local que apresenta considerável número de palafitas nas proximidades e pouca vegetação. A presença de efluentes domésticos e esgotos são retratados principalmente pela quantidade de coliformes, óleos e graxas, turbidez e teor de fósforo nas amostras coletadas em ambos os períodos e pelo grande número de pontos de descargas que aumentam a cada dia.

Immunolocalization of myosin Va in the developing nervous system of embryonic chicks

Myosins are molecular motors associated with the actin cytoskeleton that participate in the mechanisms of cellular motility. During the development of the nervous system, migration of nerve cells to specific sites, extension of growth cones, and axonal transport are dramatic manifestations of cellular motility. We demonstrate, via immunoblots, the expression of myosin Va during early stages of embryonic development in chicks, extending from the blastocyst period to the beginning of the fetal period. The expression of myosin Va in specific regions and cellular structures of the nervous system during these early stages was determined by immunocytochemistry using a polyclonal antibody. Whole mounts of chick embryos at 24-30-h stages showed intense immunoreactivity of the neural tube in formation along its full extent. Cross-sections at these stages of development showed strong labeling in neuroepithelial cells at the basal and apical regions of the neural tube wall. Embryos at more advanced periods of development (48h and 72 h) showed distinctive immunolabeling of neuroepithelial cells, neuroblasts and their cytoplasmic extensions in the mantle layer of the stratified neural tube wall, and neuroblasts and their cytoplasmic extensions in the internal wall of the optic cup, as well as a striking labeling of cells in the apparent nuclei of cranial nerves and budding fibers. These immunolocalization studies indicate temporal and site-specific expression of myosin Va during chick embryo development, suggesting that myosin Va expression is related to recruitment for specific cellular tasks.

Episcopal Church Home For Children Records - Accession 31

The Episcopal Church Home For Children Records are a valuable source on the Church���s historical effort to extend its services for the social improvement of South Carolina (in this case the Episcopal Diocese’s program for destitute children.) The Episcopal Church Home was established in 1850 in Charleston, S.C. for orphan girls and was chartered by the S.C. General Assembly in 1852. The collection consists of a history, minutes, reports of the annual meetings, general correspondence, superintendent’s records, health records, attendance registers, financial records, newsletters (both bound and unbound), and photographs.
