25. FILOGEOGRAFIA E ESTRUTURA GENÉTICA DE POPULAÇÕES DA MUNGUBEIRA (PSEUDOBOMBAX MUNGUBA (MART. &ZUCC.) DUGAND, MALVACEAE - BOMBACOIDEAE) NA AMAZÔNIA BRASILEIRA
The current structure of plant populations reflects not only the present patterns of genetic exchange within and between populations, but also historical gene flow, lineage isolation, and maintenance of ancestral polymorphisms. Phylogeography is a field study interested in the reconstruction of history of species to understand their origins and responses to

26. Trophic ecology of five flatfishes species (Actinopterygii, Pleuronectiformes) in the Sepetiba Bay, Rio de Janeiro, Brasil / Ecologia trófica de cinco espécies de linguados (Actinopterygii, Pleuronectiformes) na Baía de Sepetiba, Rio de Janeiro, Brasil
The aim of this work was to describe the trophic ecology of the five most abundant flatfishes species (Actinopterygii, Pleuronectiformes) in the Sepetiba Bay: Achirus lineatus, Trinectes paulistanus, Citharichthys spilopterus, Etropus crossotus and Symphurus tessellatus. Patterns of distribution were determined, and the feeding habits and resources partition

27. Population structure and genetic variability of mainland and insular populations of the Neotropical water rat, Nectomys squamipes (Rodentia, Sigmodontinae)
Seven microsatellite loci were used to investigate the genetic variability and structure of six mainland and two island populations of the Neotropical water rat Nectomys squamipes, a South American semi-aquatic rodent species with a wide distribution. High levels of variability were found within mainland populations while island populations were less variabl

28. NÃveis de concentraÃÃes de metais pesados em macroalgas e em sedimentos marinhos do Estado de Pernambuco - Brasil
The strong industrial and agricultural activities in Pernambuco State are contributing heavily to the contamination of the coastal waters with heavy metals and unfortunetly it is increasing constantly. As this subject is explored in many aspects and as there exists already a great production of papers, in order to diagnostic the present situation and to sugg

29. Processo de aprendizagem da PETROBRAS : programas de capacitação tecnologica em sistemas de produção offshore
This thesis aims showing PETROBRAS offshore technological programs. The remarkable growth of oil production in the last decades in Brasil is connected with the skilled extraction at large sea fields. These initiatives have been possible due to the technological development being carried on by PETROBRAS through research programs. The discovery of large sea oi

30. Effects of high altitude hypoxia on left ventricular systolic time intervals in man.
Effects of high altitude hypoxia on systolic time intervals were examined in 34 healthy men: 20 sea level residents studied at rest and at the end of 3 minutes steady isometric (handgrip) exercise at sea level and then serially for the first 5 days and on the tenth day, at an altitude of 3658 m, and I4 permanent residents at high altitude studied at high alt

31. Contribution of climate-driven change in continental water storage to recent sea-level rise
Using a global model of continental water balance, forced by interannual variations in precipitation and near-surface atmospheric temperature for the period 1981–1998, we estimate the sea-level changes associated with climate-driven changes in storage of water as snowpack, soil water, and ground water; storage in ice sheets and large lakes is not considere

32. The effect of altitude hypoxia on glucose homeostasis in men.
1. Exposure to altitude hypoxia elicits changes in glucose homeostasis with increases in glucose and insulin concentrations within the first few days at altitude. Both increased and unchanged hepatic glucose production (HGP) have previously been reported in response to acute altitude hypoxia. Insulin action on glucose uptake has never been investigated durin

33. Relative Effect of Transcription-Level and Translation-Level Control of Protein Synthesis during Early Development of the Sea Urchin*
Newly synthesized proteins were pulse labeled with radioactive amino acids at several developmental stages of the sea urchin, Arbacia punctulata—in normal embryos and in embryos continuously exposed to the drug Dactinomycin. The soluble proteins were fractionated by electrophoresis through polyacrylamide gels. A simple procedure for complete solubilization

35. Effect of altitude on spirometric parameters and the performance of peak flow meters.
BACKGROUND: Portable peak flow meters are used in clinical practice for measurement of peak expiratory flow (PEF) at many different altitudes throughout the world. Some PEF meters are affected by gas density. This study was undertaken to establish which type of meter is best for use above sea level and to determine changes in spirometric measurements at alti

36. Relative sea levels from tide-gauge records
Mean annual sea levels at 247 tide-gauge stations of the world exhibit a general rise of relative sea level of about 3 mm/year during the past 40 years. In contrast, general uplift of the land is typical of high northern latitudes, where unloading of the crust by melt of Pleistocene ice sheets is significant. Erratic movements are typical of belts having cru
