1. Pedodiagenetic Characterization of Cretaceous Paleosols in Southwest Minas Gerais, Brazil
ABSTRACT The influence of post-burial geological processes on preserving pedogenic properties has great importance in identifying ancient paleosols both in the field and in a laboratory. However there are not many publications that focus on characterizing paleosol diagenesis. As temperature and pressure progressively increase, evidence of pedogenesis is modi

2. Controles deposicionais sobre a composição primária, padrões diagenéticos e porosidade dos depósitos mistos siliciclásticos-carbonáticos dos campos de fazenda Santa Luzia e fazenda São Rafael, Bacia do Espírito Santo
A Bacia do Espírito Santo, situada na costa do estado homônimo, margem leste brasileira, contém algumas das mais importantes descobertas recentes de petróleo no país. Os reservatórios dos campos de Fazenda Santa Luzia e Fazenda São Rafael são constituídos por depósitos do Grupo Barra Nova (Albiano), e caracterizados pela intercalação de rochas si

3. Arquitetura estratigráfica e arcabouço estrutural dos depósitos fluviais albianos da base da Formação São Mateus no Norte da Bacia do Espírito Santo
The main aim of this dissertation is make at the high-resolution stratigraphic subdivision of the basal section from the São Mateus Formation, Albian the Espírito Santo Basin. The interval studied is consists predominantly of alluvial deposits. Against the difficulties presented for the stratigraphic correlation of these deposits, as discussed by Wright &M

4. Sedimentary facies and provenance of the Bebedouro Formation, Neoproterozoic (BA) / Fácies sedimentares e proveniência da Formação Bebedouro, Neoproterozóico (BA)
The sedimentary record of Neoproterozoic age has become a major subject of research since the rebirth of the models of extreme glaciation and rapid climatic changes for the period, including the Snowball Earth hypothesis. These models are founded on the identification, in all continents, of Neoproterozoic diamictites directly overlain by carbonates, which ar

5. Análise estratigráfica de alta resolução do intervalo praguiano-neoemsiano (Formação Ponta Grossa), na borda leste da Bacia do Paraná, com base em dados geoquímicos e sedimentológicos / High resolution stratigraphic analysis of praguian-neoemsian interval (Ponta Grossa Formation), at eastern edge of Parana Basin, with base on geochemical and sedimentologic datas
This work is the result of detailed stratigraphic analysis on the sedimentary record of Praguian?Emsian later interval, established on core samples of four wells in the Paleozoic outcrop section, eastern edge of Paran? Basin. Data set was obtained by means of sedimentology, gamma spectrometry and organic geochemistry (total organic carbon and pirolysis Rock-

6. Estudo geológico e geofísico da falha de carnaubais, Bacia Potiguar-RN, e implicações neotectônicas
The segment of Carnaubais Fault located in the southeasthern portion of Guamaré Graben (Potiguar Basin) was studied. Several structures were detected and some of them strongly suggest that the last movements in Carnaubais Fault are of Neotectonic age. The study comprises an integrated interpretation of geologic, geomorphologic and geophysical data (gravimet

7. Tobacco Transgenic Lines That Express Fenugreek Galactomannan Galactosyltransferase Constitutively Have Structurally Altered Galactomannans in Their Seed Endosperm Cell Walls1
Galactomannans [(1→6)-α-d-galactose (Gal)-substituted (1→4)-β-d-mannans] are major cell wall storage polysaccharides in the endosperms of some seeds, notably the legumes. Their biosynthesis in developing legume seeds involves the functional interaction of two membrane-bound glycosyltransferases, mannan synthase (MS) and galactomannan galactosyltransfer
