Particle-attached and free-living bacterial communities in a contrasting marine environment: Victoria Harbor, Hong Kong

Diversity of particle-attached and free-living marine bacteria in Victoria Harbor, Hong Kong, and its adjacent coastal and estuarial environments was investigated using DNA fingerprinting and clone library analysis. Denaturing gradient gel electrophoresis (DGGE) analysis of 16S rRNA genes showed that bacterial communities in three stations of Victoria Harbor were similar, but differed from those in adjacent coastal and estuarine stations. Particle-attached and free-living bacterial community composition differed in the Victoria Harbor area. DNA sequencing of 28 bands from DGGE gel showed Alphaproteobacteria was the most abundant group, followed by the Bacteroidetes, and other Proteobacteria. Bacterial species richness (number of DGGE bands) differed among stations and populations (particle-attached and free-living; bottom and surface). BIOENV analysis indicated that the concentrations of suspended solids were the major contributing parameter for the spatial variation of total bacterial community structure. Samples from representative stations were selected for clone library (548 clones) construction and their phylogenetic distributions were similar to those of sequences from DGGE. Approximately 80% of clones were affiliated to Proteobacteria, Bacteroidetes and Cyanobacteria. The possible influences of dynamic pollution and hydrological conditions in the Victoria Harbor area on the particle-attached and free-living bacterial community structures were discussed.

Projeto e implementação de um modelo de controle de acesso para aplicações Web.

O objetivo deste trabalho é apresentar um modelo de controle de acesso para aplicações Web (Sistema de Informação sobre o mercado de software brasileiro) e mostrar como ele pode ser reutilizável para outras aplicações que utilizam o paradigma cliente-servidor. A ênfase do trabalho será, portanto, mostrar o modelo de controle de acesso e sua implementação usando software livre.

Tecnologia Web para suporte ao licenciamento ambiental.

Ferramentas computacionais que disponibilizem informações geográficas e descritivas sobre temas relacionados aos recursos ambientais potencializam agilidade e eficiência a vários processos de gestão ambiental, em especial aos relacionados com licenciamento ambiental.

Sistema de Informação de solos brasileiros.

Com o objetivo de possibilitar o armazenamento e a disponibilização das informações sobre os solos brasileiros, a Embrapa Informática Agropecuária e a Embrapa Solos investem no desenvolvimento de um Sistema de Informações de Solos. O sistema foi concebido para armazenar dados detalhados sobre este recurso natural, para que possam ser acessados pela internet, combinados e analisados sob vários pontos de vista. Seu banco de dados reunirá informações de solos coletados e analisados de todas as regiões do Brasil. A partir desta base de dados serão desenvolvidas aplicações para a tomada de decisões do agronegócio, em zoneamento agrícola, na estimativa da produtividade de culturas, no ensino e na pesquisa.

Tutorial SGP: Sistemas Gestor de Publicações da Embrapa Informática Agropecuária. Versão 2.0

O Sistema Gestor de Publicações - SGP é uma ferramenta que tem como objetivo principal registrar todos os passos do processo das publicações internas da Embrapa Informática Agropecuária. Baseado nos softwares de submissão mais utilizados pela comunidade científica internacional, contempla as funções de submissão de documentos, acompanhamento, emissão de relatórios e pareceres, além do acompanhamento, pelo autor, do andamento do trabalho de seu trabalho. Todas suas funções serão detalhadas, porém separadas em processos mais complexos do menu principal: Trabalhos, Acompanhamento e Administração. Este manual, apesar de ser utilizado por vários usuários - autor, revisor, membros do CP, Administrador do sistema, Bibliotecário e Revisor de Português, terá sua linguagem direcionado para a(o) Secretária(o) e Presidente do Comitê de Publicações. Que, pela natureza de suas funções, serão a interface principal entre todos usuários e a real utilização do sistema.

Large Decrease of Fluctuations for Supercooled Water in Hydrophobic Nanoconfinement

Using Monte Carlo simulations we study a coarse­grained model of a water layer confined in a fixed disordered matrix of hydrophobic nanoparticles at different particle concentrations c. For c = 0 we find a 1st order liquid­liquid phase transition (LLPT) ending in one critical point at low pressure P. For c > 0 our simulations are consistent with a LLPT line ending in two critical points at low and high pressure. For c = 25% at high P and low temperature T we find a dramatic decrease of compressibility, thermal expansion coefficient, and specific heat. Surprisingly, the effect is present also for c as low as 2.4%. We conclude that even a small presence of nanoscopic hydrophobes can drastically suppress thermodynamic fluctuations, making the detection of the LLPT more difficult.

Disciplined Seeing: Forms of Christianity and Forms of Life

Contribution to the knowlegde of Galician xenoflora (NW Iberian Peninsula, Spain).

Information on 12 exotic plants of diverse interest for the Galician flora are presented. All of them were collected in Ribeira council (SW of the A Coruña province). The total includes 8 novelties at a regional level (Aeonium haworthii, Aloe mitriformis, Brugmansia × candida, Nephrolepis cordifolia, Osteospermum ecklonis, Pelargonium capitatum, Sedum mexicanum, Sparaxis tricolor), and 2 provincial novelties. In addition, information on two taxa hardly mentioned in the literature on Galician vascular flora is also included. All the cited specimens are deposited at the SANT Herbarium.

Polycyclic aromatic hydrocarbons (PAHS) (I): Measures of prevention and control

Measures of prevention and control against polycyclic aromatic hydrocarbons (PAHs) focus on an official food control, a code of best practice to reduce PAHs levels by controlling industry and in the development of a chemopreventive strategy. Regulation (EU) 835/2011 establishes maximum levels of PAHs for each food group. In addition, Regulations (EU) 333/2007 and 836/2011 set up the methods of sampling and analysis for its official control. Scientific studies prove that the chemopreventive strategy is effective against these genotoxic compounds effects. Most chemopreventive compounds studied with proven protective effects against PAHs are found in fruit and vegetables.

Pathophysiology of feline hyperadrenocorticism clinical. Case presentation

Hyperadrenocorticism is a rare endocrine disease in the cat; it is characterized by elevated blood cortisol level that generates numerous clinical signs including hyperglycemia, polyuria, polydipsia, polyphagia and skin diseases. The average age of onset is around 10 years. This disease usually occurs link with other endocrine disorders such as diabetes mellitus.The disease can be produced by functional alteration of the pituitary gland or the adrenal. A case report, with differential diagnosis and review of the literature, is presented.
