José Carlos Rodrigues: um interlocutor privilegiado nos bastidores do poder (1867-1915)

A presente tese examina a história de vida do homem de negócios e jornalista fluminense José Carlos Rodrigues (1844 1923), detendo-se, em particular, no lapso de tempo compreendido entre os anos de 1867 e 1915. A primeira data corresponde ao início da temporada de José Carlos nos Estados Unidos da América e a segunda, ao seu afastamento do Jornal do Commercio, órgão da imprensa carioca, do qual foi proprietário entre 1890 e 1915. A pesquisa empreendida analisa as amizades pessoais, além dos vínculos profissionais estabelecidos por Rodrigues, a partir de sua inserção nos campos da imprensa, da política, dos negócios e das letras, no Rio de Janeiro, em Nova York e em Londres, cidades em que viveu no período abordado. Evidencia, também, que essa ampla rede de sociabilidade foi sendo tecida, progressivamente, não apenas pelo conhecido caráter empreendedor do publicista, mas, sobretudo, graças a arranjos sociais e políticos, através do acesso a informações privilegiadas. Mais do que bibliófilo e filantropo, José Carlos Rodrigues atuou nos círculos políticos, interferindo ora de forma clara, ora nos bastidores do poder.

The reproductive biology of the porbeage shark (Lamna nasus) in the western North Atlantic Ocean

Reproductive organs from 393 male and 382 female porbeagles (Lamna nasus), caught in the western North Atlantic Ocean, were examined to determine size at maturity and reproductive cycle. Males ranged in size from 86 to 246 cm fork length (FL) and females ranged from 94 to 288 cm FL. Maturity in males was best described by an inflection in the relationship of clasper length to fork length when combined with clasper calcification. Males matured between 162 and 185 cm FL and 50% were mature at 174 cm FL. In females, all reproductive organ measurements related to body length showed a strong inflection around the size of maturity. Females matured between 210 and 230 cm FL and 50% were mature at 218 cm FL. After a protracted fall mating period (September–November), females give birth to an average of 4.0 young in spring (April−June). As in other lamnids, young are nourished through oophagy. Evidence from this study indicated a one-year reproductive cycle and gestation period lasting 8–9 months.

Coastal climate reflected in carbon-13/carbon-12 ratio of organic carbon in varved sediment from Santa Barbara basin

A 1844-1987 time-series of carbon stable isotope ratios from dated sedimentary total organic carbon from the center of the Santa Barbara basin is compared with historical climate and oceanographic records. Carbon derived from carbon-13-depleted phytoplankton and carbon-13-enriched kelp appear responsible for a large part of the isotopic variance in sedimentary total organic carbon. El Niño/Southern Oscillation events are recorded by the isotopic response of marine organic carbon in sediments.

Polyculture of freshwater prawn, Macrobrachium rosenbergii, de Man with carps: effects of prawn stocking density

Effects of three stocking densities, viz., 35, 50 and 65/decimal (1 decimal = 40.48 m2) of juvenile freshwater prawn (Macrobrachium rosenbergii) on prawn and fish production were tested in a polycuture system with silver carp (Hypophthalmichthys molitrix), catla (Catla catla), Grass carp (Ctenophmyngodon idella) and silver barb (Barbodes gonionotus). The fish stocking density was 19/decimal with the species combination of silver carp-10, catlac-6, grass carp-1 and silver barb-2. In a 8-month culture period, the prawn yield 423 ± 144 kg/ha was significantly lower (P< 0.5) with the prawn stocking density of 35/decimal than that of 548 ± 178 kg/ha and 662 ± 243 kg/ha with 50 and 65/decimal respectively. The fish production (1844-1891 kg/ha) did not differ significantly (p <0.05) among the three treatments indicating that prawn stocking densities had no influence on fish yield. The lower mean harvest weight (62 g) and survival rate (67 g) and higher yield (2.67 kg/decimal) with the highest stocking rate of prawn reveals that as density was increased, prawn survival and individual weight at harvest decreased but total yield increased.

滇池典型湖湾沉积物氮磷化学特性及疏浚层推算

以滇池围湖试验区海东湾和马村湾的沉积物为研究对象,对沉积物柱状样按每3cm分层,测试有机质、总磷及赋存形态磷(包括不稳定性磷、铁铝结合态磷、钙结合态磷、残渣磷)、总氮、亚硝酸盐氮、硝酸盐氮和氨氮等指标.结果表明:近些年来,2湾遭受的氮、磷内源负荷比以前大;铁铝结合态磷在磷的各形态中含量最高,氨氮所占总氮的比例较其它湖泊偏低;也发现海东湾和马村湾这2个湖湾在9~12cm层总磷、总氮呈现污染减轻的趋势,同时在24~39cm的深度上,总磷、总氮指标再次出现转折,考虑可行性和经济制约,24~39cm处可作为疏浚层

Multiwall nanotubes, multilayers, and hybrid nanostructures: new frontiers for technology and Raman spectroscopy.

Technological progress is determined, to a great extent, by developments in material science. Breakthroughs can happen when a new type of material or new combinations of known materials with different dimensionality and functionality are created. Multilayered structures, being planar or concentric, are now emerging as major players at the forefront of research. Raman spectroscopy is a well-established characterization technique for carbon nanomaterials and is being developed for layered materials. In this issue of ACS Nano, Hirschmann et al. investigate triple-wall carbon nanotubes via resonant Raman spectroscopy, showing how a wealth of information can be derived about these complex structures. The next challenge is to tackle hybrid heterostructures, consisting of different planar or concentric materials, arranged "on demand" to achieve targeted properties.
