Ensaio de caracterização estratigráfica do cretáceo no estado de são paulo: grupo bauru

Abstract: Mapping survey over 135,000 km 2 in the State of Sao Paulo, made by Departamento de Aguas e Energia Eletrica do Estado de Sao Paulo(DAEE) in cooperation with other organisations, allowed the stratigraphical characterization of the Cretaceous rocks younger than Serra Geral Formation (lower Cretaceous) in that region. Due to the regional stratigraphical analysis of these sediments is proposed for them the term Bauru Group which is constituted by the following four Formations: 1) Caiua Formation: fine to medium sandstone with regular to good sorting and purple color,bearing large cross stratification; occurrence limited to the Pontal do Paranapanema region; it is in unconformity over basalts of the Serra Geral Formation. 2) Santo Anastacio Formation: very fine to medium sandstone, red to purple colors; low angle cross stratifications to horizontal bedding, with rare mudstone beds intercalated; occurrence mainly in southwestern portion of Sao Paulo State; gradational over Caiua Formation and with discordance over basalts. 3) Adamantina Formation: a) Aracatuba lithofacies - thick beds of mudstones, dark brown to greenish grey colors, with variations to siltstones and claystones; restricted occurrence in the southwestern portion of Sao Paulo State and wide one in the western and northwestern portion of the State; overlying Santo Anastacio Formation and Serra Geral Formation; b) Taciba lithofacies - beds of very fine to fine sandstones, with small to large size cross stratifications, intercalated with beds of reddish to brownish sandy mudstones; incipient lamination and sandstone lens; wide occurrence from south to the north of the State over Santo Anastacio Formation (south), Aracatuba lithofacies (west, and northwest) and basalts (northeast); c) Ubirajara Formation - coarser sandstones than that one from Taciba lithofacies, textural and mineralogical imatures, with occurrence in mid-east portion of the State over basalts, lateral gradation to Taciba lithofacies toward west and north. 4) Marilia Formation: coarse to conglomeratic sandstones plentiful of calciferous cement and nodules; occurrence in the wathersheds of the principal drainages in Sao Paulo State inland. The contact relationship and regional distribution of the stratigraphic unities suggest a partial contemporaneous deposition in a complex fluvial system, with regional and chronological variations in the clastic affluence, in the climatic characteristics, in the subsidence ratio and in the marginal areas uplift rate.

Reproductive biology in the primitive relic Angiosperm Drimys brasiliensis (Winteraceae)

Abstract: From field observations onDrimys brasiliensis, principally in the Botucatu region of Sao Paulo State, Brazil, new data on the reproductive biology, the rhythm of growth, and the development of lateral cymose inflorescences, flowers and fruits are presented. Pollination accelerates the rate of flower-development for about 4–6 days. Pollination experiments show thatD. brasiliensis is not self-sterile; because of mechanical devices the sticky pollen grains do not normally come into contact with the stigmata unless an animal pollen vector is involved. The pollinators are diurnalColeoptera, Diptera andThysanoptera which eat from the pollen, lick from the stigmatic exudates and (in case of the flies) probably also from the staminal glands. Fruit- and seedeaters are birds which seem to be the main dispersal agents. Establishment of new individuals normally is through seedlings, but also by vegetative propagation through plagiotropous branches which may root and separate from the mother plant. The morphological, developmental and reproductive aspects inD. brasiliensis are discussed in a wider context, compared with data from otherMagnoliidae, and related to aspects of early Angiosperm evolution.

Size distribution of Amazon River bed sediment

Abstract: The first recorded observations of bed material of the Amazon River were made in 1843 by Lt William Lewis Herndon of the US Navy, when he travelled the river from its headwaters to its mouth, sounding its depths, and noting the nature of particles caught in a heavy grease smeared to the bottom of his sounding weight1. He reported the bed material of the river to be mostly sand and fine gravel. Oltman and Ames took samples at a few locations in 1963 and 1964, and reported the bed material at Obidos, Brazil, to be fine sands, with median diameters ranging from 0.15 to 0.25 mm (ref. 2). We present here a summary of particle-size analyses of samples of streambed material collected from the Amazon River and its major tributaries along a reach of the river from Iquitos in Peru, ∼3,500 km above Macapa Brazil, to a point 220 km above Macapa3.

An electron microscopic study of spermatogenesis in the drone of Scaptotrigona postica (Hymenoptera, Apidae)

Abstract: Gonocyst growth in the drone of S. postica is characterized by a series of 5 synchronous mitoses in which cytokinesis is incomplete, and the original cells remain interconnected until spermatozoa formation. During meiosis the division of spermatocytes I was terminated with an anomalous metaphase plate formation at the end of prophase (I). A concentric endoplasmic reticulum encircled the metaphase chromosomes; though microtubules were present, spindles were not formed. This abortive division also affected the particular behavior of the centrioles. Although the centrioles proliferated during prophase I, they did not give rise to a spindle, but became associated with the formation of centriolar blebs at cell surface, and seemed eventually to be eliminated. In S. postica, the chromosome number is maintained due to the abortiveness of the first meiotic division; therefore, chromosome distribution is normal during the subsequent division. The second meiotic division resulted in the formation of two spermatids, ...

Some studies on moisture conditions in the Southern Hemisphere

Abstract: Vertical cross-sections of the seasonal mean atmospheric humidity conditions on a planetary scale for the Southern Hemisphere are presented. The fields of mean precipitable water content are analysed for the four seasons of the year. Zonally averaged values of the various quantities at several levels are presented and compared, wherever possible, with previous results. The structure of these fields in association with general circulation patterns of the atmosphere is discussed. Precipitation efficiencies for the three continents, South America, Africa and Australia are estimated. Vertical cross-sections of atmospheric cooling rates for January and July are presented.

Contribuicao a geologia do grupo Pinhal (SP e MG)

Abstract: The Pinhal Group is an imporlant lithostratigraphic unit, in the NE of the State of Sao Paulo and SSW of the State of Minas Gerais, Southern Brazil. The Pinhal and Socorro Complexes are the main granitic-migmatitic areas of this unit, including "migmatites forming granites", migmatites, "normal granites" and several medium to high grade metamorphic country rocks. The granitic suite include various equigranular and porphyroid types and porphyritic, pegmatitic and aplitic dikes. Geochronologic age determinations indicate their relation with "Brazilian Cycle" (Baikalian Cycle, of Upper Precamhrian age): the country rocks belongs to the Amparo Group (Niddle Precambrian), which rocks underwent an intensive remobilization during the Brazilian Cycle. The "migmatites forming granites" are surrounded by an aureole of migmatites composed of 3 zones: the outer zone is formed by layered migmatites, the medium on by agmatitic and "schollen" migmatites; and the inner one by "schlieren", nebuliticand homophanic migmatites. The central granitic core is equigranular or porphyroid. The migmatitic aureole is frequently disturbed by faults, by "normal granite" intrusions or by the interference of adjacent aureoles; these disturbances lead to very complex (polyphasic) migmatites. Strong metassomatic phenomena affected the rocks of the Pinhal Group, at two distinc phases. The first one, of potassic nature is characterized by a intensive development of microcline megacrystals; and the second one, of sodic nature, by the formation of pure albite. In each phase, distinct metassomatic pulsations have been observed, linked with the several intrusion and tectonic events which have affected the complexes which form megadiapirs of polydiapiric nature. The big granite plutons have arise from the base of the sialic crust along "thermal channles" related to zones of tectonic weakness. During this slow ascension these bodies have 'undergone deep modifications (remobilizations), subsolidus recrystalization, metasomatism, assimilation and fractional crystalization. From the regional point of view, the Pinhal Group is correlated to the Serra dos Orgaos Group, in the Rio de Janeiro State. Economic geology in the investigated region is mainly related to pegmatites exploitation.

Humoral and cell‐mediated immunity in large non‐toxic multinodular goitre

Abstract: SUMMARY Humoral and cell-mediated immunity was investigated in fourteen patients with non-toxic multinodular goitre and ten healthy controls by in vitro methods These included determination of sheep erythrocyte and complement rosette-forming cells in the peripheral blood, immunoglobulin levels, titres of thyroglobulin and microsomal antibodies and migration inhibition test using thyroid extract and phytohemagglutinin When compared with controls the patients showed high IgA levels and positive response to thyroid antigen in the leucocyte migration inhibition test There was no correlation between the leucocyte migration results and the presence of auto-antibodies These findings indicate a possible role of cell-mediated immunity in non-toxic multinodular goitre
