The Southeast region comprises of the states of Espírito Santo (ES), Minas Gerais (MG), Rio de Janeiro (RJ) and São Paulo (SP). It covers 11% of Brazil (924,935 sq. km). Despite its comparatively small geographic size, it is the most economically developed region in South America and is responsible for nearly 60% of the Brazil's GNP. The Southeast is also the most populated region in the nation with a little less than 44% of the total population in 1986.Slide do mapa mostrando a região Sudeste. Esta região abrange os estados do Espírito Santo (ES), Minas Gerais (MG), Rio de Janeiro (RJ) e São Paulo (SP). Ela cobre apenas 11% (924.935 km quadrados) do território do Brasil. Apesar de seu pequeno tamanho, quando comparada a outras regiões, ela é economicamente a mais desenvolvida região do Brasil e da América do Sul, sendo responsável por aproximadamente 60% do Produto Nacional Bruto (PNB). O Sudeste é também a região mais populosa do país, com pouco menos que 44% do total da população brasileira em 1986
Multitrait analysis of fresh-cut cantaloupe melon enables discrimination between storage times and temperatures and identifies potential markers for quality assessments
No full textFresh-cut cantaloupe melon is valued for its aroma but is highly perishable. Temperature of storage (typically
0–5 °C) is critical for maintaining fresh-cut melon quality, but often reaches 10 °C during transportation and in
retail outlets. A comparison amongst 0, 5 and 10 °C storage temperatures for fresh-cut melon over 14 days
reveals that storage at 0 °C is optimal for avoiding increases in microbial load and loss of vitamin C especially at
later time points. However, higher temperatures maintain better the balance of esters (acetate versus nonacetate)
and phenolic content. The whole volatile organic compound (VOC) profile can be used to discriminate
both time and temperature effects especially at earlier time points. Potential VOC markers for changes in vitamin
C from day 0 to day 6 of storage (3-methyl butane nitrile) and temperature (limonene) are identified through a
multi-trait analysis
Reformulating the rj-McMC Algorithm for 3D Inversion of Passive Seismic Data for Near-Surface Characterization
No full textGeophysical subsurface characterization techniques could, due to their non-invasive nature, play a crucial role in the design and subsequent construction of infrastructure in urban & industrial environ- ments. Geo-data specialist company Fugro sees potential in upgrading their current ambient-seismic- noise-tomography workflow, to make use of state-of-the-art inversion schemes with the main goal of increasing the quality and accuracy of the initial-site characterization delivered to clients. In this thesis I explore the feasibility of utilizing the reverse-jump Markov chain Monte Carlo (rj-McMC) algorithm for the inversion of ambient seismic noise for characterization in urban & industrial environments. Specif- ically, testing the potential of scaling down this inversion algorithm to fit in a small scale, near-surface framework. To achieve this, I first carried out analyses to evaluate the appropriate Rayleigh wave frequency range, after which realistic noise hyperparameters, suited for this reduced scale problem, were obtained. Because of the potential exploitation of in-situ borehole measurements, I reformulated the Bayesian prior within the rj-McMC algorithm to implement these constraining shear wave velocity values appropriately. I conducted extensive synthetic experiments to gain insight into the behavior of this adapted algorithm, from which it was concluded that the inherent dynamic discretization partially prevents these constraints from being implemented to their full extent. Nevertheless, promising results lead me to conclude that the use of the rj-McMC algorithm for application in near-surface urban & industrial environments is feasible.Applied Geophysics | IDEA Leagu

Expression of Arabidopsis WEE1 in tobacco induces unexpected morphological and developmental changes
No full textWEE1 regulates the cell cycle by inactivating cyclin dependent protein kinases (CDKs) via
phosphorylation. In yeast and animal cells, CDC25 phosphatase dephosphorylates the CDK releasing
cells into mitosis, but in plants, its role is less clear. Expression of fission yeast CDC25 (Spcdc25) in
tobacco results in small cell size, premature flowering and increased shoot morphogenetic capacity in
culture. When Arath;WEE1 is over-expressed in Arabidopsis, root apical meristem cell size increases,
and morphogenetic capacity of cultured hypocotyls is reduced. However expression of Arath;WEE1 in
tobacco plants resulted in precocious flowering and increased shoot morphogenesis of stem explants,
and in BY2 cultures cell size was reduced. This phenotype is similar to expression of Spcdc25 and is
consistent with a dominant negative effect on WEE1 action. Consistent with this putative mechanism,
WEE1 protein levels fell and CDKB levels rose prematurely, coinciding with early mitosis. The phenotype
is not due to sense-mediated silencing of WEE1, as overall levels of WEE1 transcript were not reduced
in BY2 lines expressing Arath;WEE1. However the pattern of native WEE1 transcript accumulation
through the cell cycle was altered by Arath;WEE1 expression, suggesting feedback inhibition of native
WEE1 transcription

Perturbation of cytokinin and ethylene-signalling pathways explain the strong rooting phenotype exhibited by Arabidopsis expressing the Schizosaccharomyces pombe mitotic inducer, cdc25
No full textBackground
Entry into mitosis is regulated by cyclin dependent kinases that in turn are phosphoregulated. In most eukaryotes, phosphoregulation is through WEE1 kinase and CDC25 phosphatase. In higher plants a homologous CDC25 gene is unconfirmed and hence the mitotic inducer Schizosaccharomyces pombe (Sp) cdc25 has been used as a tool in transgenic plants to probe cell cycle function. Expression of Spcdc25 in tobacco BY-2 cells accelerates entry into mitosis and depletes cytokinins; in whole plants it stimulates lateral root production. Here we show, for the first time, that alterations to cytokinin and ethylene signaling explain the rooting phenotype elicited by Spcdc25 expression in Arabidopsis.
Results
Expressing Spcdc25 in Arabidopsis results in increased formation of lateral and adventitious roots, a reduction of primary root width and more isodiametric cells in the root apical meristem (RAM) compared with wild type. Furthermore it stimulates root morphogenesis from hypocotyls when cultured on two way grids of increasing auxin and cytokinin concentrations. Microarray analysis of seedling roots expressing Spcdc25 reveals that expression of 167 genes is changed by > 2-fold. As well as genes related to stress responses and defence, these include 19 genes related to transcriptional regulation and signaling. Amongst these was the up-regulation of genes associated with ethylene synthesis and signaling. Seedlings expressing Spcdc25 produced 2-fold more ethylene than WT and exhibited a significant reduction in hypocotyl length both in darkness or when exposed to 10 ppm ethylene. Furthermore in Spcdc25 expressing plants, the cytokinin receptor AHK3 was down-regulated, and endogenous levels of iPA were reduced whereas endogeous IAA concentrations in the roots increased.
Conclusions
We suggest that the reduction in root width and change to a more isodiametric cell phenotype in the RAM in Spcdc25 expressing plants is a response to ethylene over-production. The increased rooting phenotype in Spcdc25 expressing plants is due to an increase in the ratio of endogenous auxin to cytokinin that is known to stimulate an increased rate of lateral root production. Overall, our data reveal important cross talk between cell division and plant growth regulators leading to developmental changes
Radiation-induced root surface caries restored with glass-ionomer cement placed in conventional and ART cavity preparations: Results at two years
No full textThe document attached has been archived with permission from the Australian Dental Association (8th Jan 2008). An external link to the publisher’s copy is included.Background: There are no published studies comparing the clinical performances of more-viscous glass-ionomer cement (GIC) restorations when placed using conventional and atraumatic restorative treatment (ART) cavity preparation methods to restore root surface caries. Methods: One dentist used encapsulated Fuji IX GP and Ketac-Molar to restore 72 conventional and 74 ART cavity preparations for 15 patients who had received cervicofacial radiation therapy. Two assessors evaluated the restorations at six, 12, and 24 months for retention, marginal defects and surface wear, and recurrent caries. Results: After two years, the cumulative restoration successes were 65.2 per cent for the conventional and 66.2 per cent for the ART cavity preparations, without statistical or clinical significance (P>0.50). Restoration dislodgement accounted for 82.8 per cent and marginal defects for 17.2 per cent of all failures. There were no instances of unsatisfactory restoration wear or recurrent caries observed. Teeth with three or more restored cervical surfaces accounted for 79.3 per cent of all failures (P<0.0001). Conclusions: For root surface caries restored with GIC, the use of hand instruments only with the ART method was an equally effective alternative to conventional rotary instrumentation for cavity preparation. Larger restorations had higher failures, usually from dislodgement.JY Hu, XC Chen, YQ Li, RJ Smales and KH Yi
A Classe C vai às bancas: a ascensão dos tablóides populares no Brasil
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em JornalismoA primeira década do século XXI testemunhou a disseminação, no Brasil, de jornais de cunho popular impressos no formato tablóide. Um modelo de produto e negócio que deu uma nova dimensão ao segmento popular da grande imprensa, abalando o predomínio do formato standard, e que interrompeu o reinado da Folha de S. Paulo como jornal mais vendido do País. Em síntese, os também chamados populares compactos viraram a indústria jornalística brasileira de cabeça para baixo. Ou melhor, de baixo para cima: foi o segmento em questão que sustentou o crescimento de 25% obtido por esta mesma indústria no período de 2005 a 2008. Em capitais como Porto Alegre (RS), Rio de Janeiro (RJ) e Belo Horizonte (MG), o mercado leitor de jornais aumentou significativamente. De um dia para o outro, centenas de milhares de brasileiros das classes C e D, sobretudo os mais jovens, passaram a consumir jornal com o surgimento dos tablóides populares. A observação desse importante fenômeno suscitou questionamentos. Por exemplo: quais são os fatores, tanto os conjunturais como os inerentes ao negócio e ao produto, que explicam o estrondoso sucesso comercial de impressos desse tipo? O que interessa ao leitor do popular compacto, ou seja, quais são os valores-notícia que guiam os produtores na seleção do conteúdo e na organização editorial desses diários? Estamos diante de uma nova escola de jornalismo popular? Responder a estas perguntas é o objetivo do presente trabalho, que se propõe a tal desafio amparado na visão de jornalistas que atuam ou atuaram em tablóides populares e na análise de conteúdo dos jornais Diário Gaúcho (RS), Meia Hora (RJ) e Super Notícia (MG), os três principais títulos do segmento e que firmaram lugar entre os 10 mais vendidos do País.The first decade of this century witnessed the spread, in Brazil, of newspapers printed in tabloid format and aimed at readers with lower purchasing power. This new product and business model interrupted the reign of Folha de S. Paulo as the best-selling newspaper in the country, gave a new dimension to the popular segment of the mainstream media and began to threaten the dominance of the standard format. Summarizing, the also called popular compact turned upside down the newspaper industry in Brazil. Or rather, from bottom to top: the segment in question sustained the growth of 25% reached by that same industry between 2005 and 2008. In cities such as Porto Alegre (RS), Rio de Janeiro (RJ) and Belo Horizonte (MG) the number of newspaper readers increased significantly. Suddenly, hundreds of thousands of brazilians from middle class, especially those in the age of 10 to 39 years old, began to consume newspaper with the outbreak of popular tabloids. The observation of this important phenomenon has raised questions such as: what are the main factors related to the commercial success of such newspapers? What are the news values that guide producers in the selection of editorial content? We are facing a new school of popular journalism? The answers to these questions is what this paper seeks, by knowing the perspective of journalists who act or acted in popular tabloids and producing content analysis of the following newspapers: Diário Gaúcho (RS), Meia Hora (RJ) and Super Notícia (MG). Placed among the 10 most sold newspapers in the country, they represent the three main titles in the segment that we are here studying
