Bauru e São José dos Campos: Shopping Centers e Espaço Urbano

A monografia aqui apresentada tem como foco o estudo do processo de estruturação do espaço urbano, com atenção para o papel dos shopping centers. Estes espaços de comercialização de bens e serviços são muito importantes para compreender tal processo e se trata de algo extremamente recente considerando-se o longo processo de urbanização, visto que sua expansão, como fenômeno urbano no Brasil é do inicio da década de 1980. O estudo privilegiou a caracterização e análise das cidades que apresentam população na faixa de 100 a 600 mil habitantes e que na sua estrutura urbana apresentem este empreendimento como um elemento que agregue ou não o poder de constituição e/ou (re)definição de centralidades, dinâmica esta bastante influenciada pela construção deste equipamento de lazer e consumo em uma cidade. Sendo assim, para o desenvolvimento deste estudo, procuramos nos nortear em questões que abarcassem qual a relação destes empreendimentos, quando existentes nas cidades, com a centralidade principal, para assim, tentarmos compreender se os mesmos desempenham a criação de novas centralidades, ou reforçam a centralidade principal já existente, concebida pela estruturação que o centro desempenha

Rochas calciossilicáticas e feldspáticas na região de Castro Alves e Rafael Jambeiro (BA)

The towns of Castro Alves and Rafael Jambeiro, central-east of Bahia state, are located in the east of São Francisco Craton, in granulite terrains of Salvador-Curaçá Belt, formed in Paleoproterozoic. The region of study contains ortognaisses of Caraíba Complex, metamafic and metaultramafic rocks of São José do Jacuípe Suite, metasedimentary rocks of Tanque Novo-Ipirá Complex, granitoids, pegmatites and alkaline rocks. The study carried out regional and detailed geological mapping in addition to petrographical and geochemical characterization of six areas in the search for targets of feldspar and white diopside, minerals used in ceramic industry. The areas consist of granitic ortognaisses interspersed with lenses of mafic granulite rocks, calc-silicate rock, banded iron formations, paragnaisses, quartzites, and bodies of quartz-feldspar or feldspar pegmatites and alkaline rocks that fill discontinuities. The region of study contains four deformations phases, with a predominance of ductile structures. The foliation Sn has N30E to N70W direction, high angle of dip and is characterized by compositional banding of granoblastic and felsic bands interspersed with nematoblastic or lepidoblastic mafic bands. A mineral or stretching lineation Ln is associated with Sn and has trend of S55E to S72E. The rocks have been suffered a regional metamorphism with granulite facies peak and partial retrogression to greenschist facies. Geochemical studies indicate that the green coloring calc-silicate rocks have lower SiO2, MgO and higher Fe2O3 content compared with white calcssilicate rocks. The alkaline rocks of the studied area have higher Na2O, SiO2 and lower K2O, Fe2O3 content compared with others Paleoproterozoic alkaline rocks of Bahia state. The targets of diopside are associated with white calc-silicate rocks, while the targets of feldspar are associated with paragnaisses, pegmatites and alkaline rocks

Prognostic factors for survival in patients with colorectal liver metastases: experience of a single brazilian cancer center

CONTEXT: Liver metastases are a common event in the clinical outcome of patients with colorectal cancer and account for 2/3 of deaths from this disease. There is considerable controversy among the data in the literature regarding the results of surgical treatment and prognostic factors of survival, and no analysis have been done in a large cohort of patients in Brazil. OBJECTIVES: To characterize the results of surgical treatment of patients with colorectal liver metastases, and to establish prognostic factors of survival in a Brazilian population. METHOD: This was a retrospective study of patients undergoing liver resection for colorectal metastases in a tertiary cancer hospital from 1998 to 2009. We analyzed epidemiologic variables and the clinical characteristics of primary tumors, metastatic disease and its treatment, surgical procedures and follow-up, and survival results. Survival analyzes were done by the Kaplan-Meier method and the log-rank test was applied to determine the influence of variables on overall and disease-free survival. All variables associated with survival with P<0.20 in univariate analysis, were included in multivariate analysis using a Cox proportional hazard regression model. RESULTS: During the period analyzed, 209 procedures were performed on 170 patients. Postope-rative mortality in 90 days was 2.9% and 5-year overall survival was 64.9%. Its independent prognostic factors were the presence of extrahepatic disease at diagnosis of liver metastases, bilateral nodules and the occurrence of major complications after liver surgery. The estimated 5-year disease-free survival was 39.1% and its prognostic factors included R1 resection, extrahepatic disease, bilateral nodules, lymph node involvement in the primary tumor and primary tumors located in the rectum. CONCLUSION: Liver resection for colorectal metastases is safe and effective and the analysis of prognostic factors of survival in a large cohort of Brazilian patients showed similar results to those pointed in international series. The occurrence of major postoperative complications appears to be able to compromise overall survival and further investigation in needed in this topic.

Foro técnico: La pesca en Gran Canaria

[ES] foro organizado por la Universidad de Las Palmas de Gran Canaria y la Comisión de Pesca de la Unión Europea celebrado en la Facultad de Ciencias del Mar de la Universidad de Las Palmas de Gran Canaria, el 25 de enero de 2013. Presenta el acto el Rector de la Universidad de Las Palmas de Gran Canaria, don José Regidor García, el Decano de la Facultad de Ciencias del Mar, don Melchor González Dávila, el Presidente de la Comisión de Pesca del Parlamento Europeo, don Gabriel Mato Adrover, el Secretario General de Pesca del Ministerio de Agricultura, Alimentación y Medio Ambiente, don Carlos Domínguez, finalmente el Consejero de Agricultura, Ganadería, Pesca y Aguas del Gobierno Canario, Juan Ramón Hernández. Asimismo, se desarrollaron tres ponencias que recogieron algunos de los aspectos más relevantes en estos momentos, como son la pesca artesanal, en la que José Pascual Fernández, del Instituto Universitario de Ciencias Políticas y Sociales de la Universidad de La Laguna, puso el acento en las experiencias existentes en cogestión y gobernanza. La economía de la pesca en Canarias fue otro de los puntos tratados, a través de la ponencia desarrollada por Javier Macías, representante de la consultoría de pesca, CANAEST, así como la opinión de la Consejería de Agricultura, Ganadería y Pesca del Cabildo de Gran Canaria, a través de la exposición que realizarán Alejandro Báez y María Marrero. La nueva propuesta de gestión pesquera para Gran Canaria, a cargo del Centro de Investigación en Biodiversidad y Gestión Ambiental del Departamento de Biología de la Universidad de Las Palmas de Gran Canaria (Bioges), en la figura de José Juan Castro, fue otro de los puntos abordados.

Regional differences in modelled net production and shallow remineralization in the North Atlantic subtropical gyre

[EN] We used 5-yr concomitant data of tracer distribution from the BATS (Bermuda Time-series Study) and ESTOC (European Station for Time-Series in the Ocean, Canary Islands) sites to build a 1-D tracer model conservation including horizontal advection, and then compute net production and shallow remineralization rates for both sites. Our main goal was to verify if differences in these rates are consistent with the lower export rates of particulate organic carbon observed at ESTOC. Net production rates computed below the mixed layer to 110m from April to December for oxygen, dissolved inorganic carbon and nitrate at BATS (1.34±0.79 molO2 m?2, ?1.73±0.52 molCm?2 and ?125±36 mmolNm?2) were slightly higher for oxygen and carbon compared to ESTOC (1.03±0.62 molO2 m?2, ?1.42±0.30 molCm?2 and ?213±56 mmolNm?2), although the differences were not statistically significant. Shallow remineralization rates between 110 and 250m computed at ESTOC (?3.9±1.0 molO2 m?2, 1.53±0.43 molCm?2 and 38±155 mmolNm?2) were statistically higher for oxygen compared to BATS (?1.81±0.37 molO2 m?2, 1.52± 0.30 molCm?2 and 147±43 mmolNm?2). The lateral advective flux divergence of tracers, which was more significant at ESTOC, was responsible for the differences in estimated oxygen remineralization rates between both stations. According to these results, the differences in net production and shallow remineralization cannot fully explain the differences in the flux of sinking organic matter observed between both stations, suggesting an additional consumption of nonsinking organic matter at ESTOC.

¿Presenta la anémona Anemonia sulcata (Pennant, 1777) comportamiento de homing?

[ES] Se estudia la capacidad de retorno al lugar de origen en Anemonia sulcata en su medio natural. Treinta y dos individuos fueron marcados en charcas intermareales, de los cuales 20 fueron desplazados, 5 y 10cm, de sus posiciones originales. Posteriormente se observó el movimiento de todos ellos en las siguientes 48h. De todas las anémonas trasladadas, un único individuo volvió exactamente a su lugar de origen recorriendo, en las primeras 24h, los 10cm que había sido desplazado. Con los resultados obtenidos en este trabajo, Anemonia sulcata no parece presentar fidelidad por un lugar en concreto dentro de su charca. Al ser trasladado desde su lugar inicial, simplemente busca un nuevo punto de fijación y lo hace tomando una dirección aleatoria. A falta de estudios más exhaustivos, se puede afirmar que esta especie no presenta comportamiento de homing.
