QUATRO RODAS 1960-63: COMO UMA REVISTA FEZ DO JORNALISMO ESPECIALIZADO FERRAMENTA PARA CRIAR A CULTURA DO AUTOMÓVEL NO COTIDIANO BRASILEIRO

Esta dissertação investiga a contribuição da revista Quatro Rodas como veículo de comunicação e agente de mudança cultural da sociedade e da imprensa brasileiras, a partir da instalação de indústrias nacionais e da adoção do carro como meio de transporte e símbolo de modernização econômica, urbana e social. Nesse sentido, contextualiza o período histórico nacional que vai da década de 1920 até o terceiro ano da publicação (1960 a 1963) e, por meio de estudo de caso, analisa o conteúdo de 58 reportagens das primeiras 36 edições reunidas em seis unidades de registro: urbanismo, medicina do trânsito, comportamento ao volante, segurança ao volante, mercado de compra e venda e mulheres e carros. O trabalho destaca a relevância da revista ao reunir de modo analítico e didático questões que envolviam os cidadãos, como motoristas ou pedestres, a indústria automobilística e as autoridades, na atribuição de, respectivamente, educar, avaliar e cobrar. Desse modo, a partir de agosto de 1960, Quatro Rodas contribui para abrir um novo campo na imprensa brasileira, antecipando questões ainda hoje presentes (e não resolvidas) nas ruas e estradas do país e desenhando o perfil do brasileiro e sua nascente paixão pelo automóvel.

(Table 1) C1 - C8 volatile compounds in sediments from DSDP Leg 63 Holes

Low-temperature diagenetic reactions (less than 50°C) are held responsible for the generation of small amounts of C1-C8 hydrocarbons (less than 100 ng hydrocarbon/g dry weight of sediment) at outer continental shelf Deep Sea Drilling Project Sites 468 and 469 (sub-bottom depths 415 m and 454 m, respectively). In contrast, Site 471 shows an exponential rise in hydrocarbon yields at depths greater than 500 meters. The high yields of C4-C8 hydrocarbons (up to 30 ng hydrocarbon/g dry weight of sediment) in this area of high geothermal and volcanic activity suggest the penetration of an active petroleum-generating zone. Similar arguments apply to Site 467, where relatively high levels (up to 3 µg hydrocarbon/g dry weight sediment) occurred in very shallow (250-600 m) sediments.

Distribution of living benthic foraminifera in sediment cores of cruise M77 Leg 1 and 2, 63-2000 µm fraction

Recent benthic foraminifera and their distribution in surface sediments were studied on a transect through the Peruvian oxygen minimum zone (OMZ) between 10 and 12°S. The OMZ with its steep gradients of oxygen concentrations allows to determine the oxygen-dependent changes of species compositions in a relatively small area. Our results from sediments of thirteen multicorer stations from 79 to 823 m water depth demonstrate that calcareous species, especially bolivinids dominate the assemblages throughout the OMZ. The depth distribution of several species matches distinct ranges of bottom water oxygen levels. The distribution pattern inferred a proxy which allows to estimate dissolved oxygen concentrations for reconstructing oxygen levels in the geological past.

(Table DR1) Argon isotope data and dating for individual >63 µm amphibole grains from Labrador Sea sediments, ODP Hole 105-647A

Variations of global and regional silicate weathering rates and paleo-ocean circulation patterns are estimated by using radiogenic isotope records, but the effects of changes in provenance are generally ignored. Here sediment provenance has been constrained through the use of Ar-Ar ages for individual detrital minerals from the Labrador Sea, which can be compared directly to the radiogenic isotope compositions from the same core material. Dramatic changes in the radiogenic isotope composition of North Atlantic Deep Water through the Quaternary Period are shown to reflect discrete changes in both sources and weathering processes accompanying Northern Hemisphere glaciation. Changes in the different radiogenic isotope systems reflect the influence of source, physical weathering, and chemical weathering, and not simply changes in the underlying weathering rate or ocean circulation patterns that are typically inferred.
