Cytogenetic description of the Amazonian brown brocket Mazama nemorivaga (Artiodactyla, Cervidae)

The Amazonian brown brocket Mazama nemorivaga (Cuvier, 1817) is a small to medium-sized deer from the Amazon rainforest and ecotones. The first karyotype described was 2n=67 to 69 + 2-7 B and FN= 69-72, in which all chromosomes were acrocentric and the X chromosome was the only submetacentric chromosome. However, important aspects of the species chromosome evolution were not resolved because of the lack of information on chromosome banding. The G-banding pattern of M. nemorivaga karyotype showedthe presence of an XX/XY1Y2 sex chromosome system as a product of an X-autosome tandem fusion, which results in a basic 2n=68, FN=70 in females and 2n= 69, FN=70 in males. The fact that this karyotype only differs from that of Capreolus capreolus pygargus (Pallas, 1771; 2n=70, FN=72+B) by X-autosome tandem fusion may corroborate the basal condition of M. nemorivaga and its proximity to the ancestral karyotype of the American Odocoileini. A derived karyotype 2n=67, XY1Y2, FN=70 + 3B from the Brazilianstate of Mato Grosso (the western Amazon) may be evidence of differentiation between western and eastern populations. © Bruno Ferreto Fiorillo et al.

Los resultados y las lecciones aprendidas del estudio comparativo sobre el uso de las tecnologías de información y comunicación (TIC) en América Latina y en Asia

La División de Comercio Internacional e Integración de la CEPAL (DCII) lanzará a fines de septiembre del 2005 el libro titulado Information Technology for Development of Small and Medium-sized Exporters in Latin America and East Asia (Tecnología de la información para el desarrollo de pequeños y medianos exportadores en América Latina y Asia del Este). Este estudio proporciona una descripción de la actual condición de las TIC y de su uso para promover el comercio internacional. Se centra en las experiencias sobre el uso de las TIC por las pequeñas y medianas empresas (pymes) en las regiones de América Latina, de Asia y el Pacífico, enfocándose, en especial, en las pymes exportadoras de 13 países investigados, que fueron seleccionados entre los países miembros del Foro de Cooperación América Latina y Asia del Este (FOCALAE). La presente edición del Boletín de FAL se basa en el resumen del citado libro.

Electronic data interchange in port management: the experience of the port of Barcelona

Every port is unique. Although all ports exist for the same basic purpose (to act as an interface in the transfer from one mode of transport to another), no two are ever organized in the same way.Ports may be classified according to: Physical conditions: location (geographical position, man-made or natural harbour, estuary location, difficult weather conditions, tides, etc.) and size (large, small or medium-sized). Use: commercial (general cargo, bulk solids, bulk liquids, oil, break bulk, mixed), passenger, sport and leisure, fishing, mixed, etc. Ownership: private, municipal, regional or State-owned. The Port Authority's role in management of the port: Overall control, i.e. the Port Authority plans, sets up and operates the whole range of services. Facilitator, i.e. the Port Authority plans and sets up the infrastructure and the superstructure, but services are provided by private companies. Landlord, i.e. the Port Authority allows private companies to be responsible for the superstructure and provide port services. Different combinations of port types will therefore give rise to different kinds of organization and different information flows, which means that the associated information systems may differ significantly from port to port. Since this paper relates to the port of Barcelona, with its own specific characteristics, the contents may not always be applicable to other ports.

Information technologies in trade facilitation and their use by msmes

This issue of the Bulletin is based on the material presented at the seminar Information Technology for Development of Small and Medium-sized Exporters in East Asia and Latin America, which was held on 23 and 24 November 2004 at the headquarters of ECLAC in Santiago, Chile. The seminar was part of the project entitled Comparative Study on East Asian and Latin American IT Industry, financed by the thematic fund for information and communication technologies (ICT) for development of the United Nations Development Programme (UNDP) and has been carried out in close collaboration with the Institute of Developing Economies (IDE), an organization that belongs to the Japanese External Trade Organization (JETRO). This article contains a discussion of the concepts, definitions and standards associated with electronic commerce, as well as the opportunities to be seized and the challenges to be met so that MSMEs can expand their electronic business.

SIMPLARCOM: simulador para planejamento de redes de comunicação sem fio utilizando realidade virtual e modelos de propagação

Este simulador é formado pela junção de técnicas de Realidade Virtual com modelos de propagação, desenvolvidos através dos estudos de rádio enlace, que descrevem a perda que o sinal transmitido sofre ao longo do percurso no ambiente. O simulador possui dois módulos. O primeiro permite a criação do ambiente virtual com o posicionamento, sobre um terreno, de prédios, árvores, carros, antenas e outras primitivas que permitem a construção de um ambiente tridimensional customizável. O segundo módulo permite a configuração dos parâmetros relacionados a propagação de sinal de antenas como a potência, a frequência, o ganho, etc., e também selecionar o modelo de propagação para a execução da simulação. Dentro deste segundo módulo, existe um submódulo responsável pelo estudo do planejamento da área de cobertura composta pelas antenas, em outras palavras, este submódulo simula a distância que cada antena no cenário consegue atingir e gera a respectiva área de cobertura. Para demonstrar a eficiência do simulador foram criados dois ambientes virtuais para testes. Um cenário representando um ambiente urbano onde empregou-se um modelo de propagação clássico, Okumura-Hata para cidades pequenas e médias, e um ambiente tridimensional arborizado utilizando um modelo especifico para simulação de propagação para regiões densamente arborizadas, desenvolvido na Universidade Federal do Pará chamado de Lyra-Castro-UFPA.

Homomorphic Sex Chromosomes and the Intriguing Y Chromosome of Ctenomys Rodent Species (Rodentia, Ctenomyidae)

Unlike the X chromosome, the mammalian Y chromosome undergoes evolutionary decay resulting in small size. This sex chromosomal heteromorphism, observed in most species of the fossorial rodent Ctenomys, contrasts with the medium-sized, homomorphic acrocentric sex chromosomes of closely related C. maulinus and C. sp. To characterize the sequence composition of these chromosomes, fluorescent banding, self-genomic in situ hybridization, and fluorescent in situ hybridization with an X painting probe were performed on mitotic and meiotic plates. High molecular homology between the sex chromosomes was detected on mitotic material as well as on meiotic plates immunodetected with anti-SYCP3 and anti-gamma H2AX. The Y chromosome is euchromatic, poor in repetitive sequences and differs from the X by the loss of a block of pericentromeric chromatin. Inferred from the G-banding pattern, an inversion and the concomitant prevention of recombination in a large asynaptic region seems to be crucial for meiotic X chromosome inactivation. These peculiar findings together with the homomorphism of Ctenomys sex chromosomes are discussed in the light of the regular purge that counteracts Muller's ratchet and the probable mechanisms accounting for their origin and molecular homology.

Geotecnologias para a análise da bacia hidrográfica do Córrego Wenzel - Rio Claro/SP: proposta de gestão de recursos hídricos

The expansion of urban in medium-sized citie, increase the importance of action planning and management of natural resources, among which water is the most important. Such action should include the integration of physical and man-made elements involved. In this context, it becomesimportant for watershed analysis and the use of geotecnologies. Thus, the objective was to demonstrate the contribution of the geo, as a tool for managing a river basin, allowing the integration of physical data and the analysis of anthropogenic environmental scenarios in urban areas. The area chosen, the basin of the Wenzel, is located in Rio Claro / SP, a city whose urbanization process has been intense and continuous. Thematic maps were generated from the physical environment: soil, slope and geological, as well as maps of land use. With regard to land use maps, these were drawn from the visual interpretation of material aerophotogrammetric, considering the years 1995 and 2010, performing an evolutionary analysis. It was observed that the area presents small variation in the physical and structural aspects, with lithological and geomorphological formation favoring the occurrence of floods, erosion and siltation. These processes are accelerated by the forms of land use, with intense urbanization during the period between 1995 and 2010, and poor preservation of permanent preservation areasand. In the floodplain areas there is a high waste disposal is the most notable environmental problem
