Resumen
OBJECTIVES: The industrialization process and nervous system cancer (NSC) mortality in a urban region of Brazil. METHOD: From registries of the State System of Data Analysis Foundation (SEADE), 103 males deaths by NSC (ICD-9) in Baixada Santista (BS), from 1980 to 1993 were selected. Mortality ratios were calculated comparing the standardized mortality rate for ages over 10 years old (G1) and for the age group from 35 to 64 years old, in the industrialized and non-industrialized areas in three periods: 1980-1993, 1980-86, 1987-93. RESULTS: A statiscally significant high mortality was observed

Resumen
Organic amendments are important sources of nutrients that release upon organic matter degradation, yet the stability of these organics in arid and semi-arid regions is relatively low. In contrast, humic substances (HS) are resistant to biodegradation and can keep nutrients in the soil available for the plant over a long time. Combinations between humic substances (HS) and mineral-N fertilizers are assumed to retain higher available nutrients in soils than those recorded for the sole application of either mineral or organic applications. We anticipate, however, that humic substances might not

Resumen
Light-dependent oxygen consumption (LDOC) was observed in isolated heterocysts and in intact and sonicated CO2-fixing Anabaena cylindrica cells. The rate of LDOC in heterocysts was about three times that of CO2-fixing cells. Photosynthetic oxygen production by A. cylindrica became light saturated at 0.3 to 0.5 mW cm−2. LDOC and nitrogenase activity (acetylene reduction) increased with light intensity up to 2.5 mW cm−2 and incubation under air resulted in much larger relative acetylene reduction increases than incubation under N2.

Resumen
ABSTRACT Transcription initiation in Archaea (archaebacteria) resembles the eucaryotic process, having been shown to involve TATA box-like promoter regions as well as TATA-binding protein and TFIIB homologs. However, little is known about transcription regulation in archaea. We have previously demonstrated that transcripts ofnifHDK2 genes, encoding Methanosarcina barkerinitrogenase, are present in N2-grown cells but not in ammonium-grown cells, indicating that nif transcription is regulated by the nitrogen source. In this study, we detected proteins in M. barkeri cell extracts that bind specif

Resumen
The work and the main scientific results of the Vinnytsia branch of the USPP from the moment of its formation to the present time are analyzed. The main direction of research is exogenous regulation of plants source-sink relations in the systems «photosynthesis—growth», «depot of assimilates—growth» in the heterotrophic phase of plant development, and «macrosymbiont—microsymbiont» in symbiotic nitrogen fixation systems. Gibberellin and antigibberellin preparations (retardants) were used to create different tension of source-sink relations. It was found that under the influence of retardants, t

Resumen
ABSTRACT The cyanobacterium Trichodesmium is an important contributor of new nitrogen (N) to the surface ocean, but its strategies for protecting the nitrogenase enzyme from inhibition by oxygen (O2) remain poorly understood. We present a dynamic physiological model to evaluate hypothesized conditions that would allow Trichodesmium to carry out its two conflicting metabolic processes of N2 fixation and photosynthesis. First, the model indicates that managing cellular O2 to permit N2 fixation requires high rates of respiratory O2 consumption. The energetic cost amounts to ∼80% of daily C fixati

Resumen
As cianobactérias caracterizam-se como o grupo de micro-organismos fotoautotrófico mais abundante encontrado nas regiões polares. Representantes deste grupo realizam a fotossíntese oxigênica e também podem fixar o nitrogênio atmosférico. A maioria dos levantamentos da comunidade de cianobactérias na Antártica tem sido realizada apenas por meio de observações microscópicas de amostras ambientais. O isolamento de linhagens e consequentes estudos fisiológicos, bem como, análises independentes de cultivo ainda são escassos.

Resumen
Aiming to simulate the underground corrosion of pipeline steels in tropic soils, the electrochemical behavior and corrosion morphology of API 5LX65 steel were studied in 0.01molL−1 Na2SO4 solutions with additions of humic (HA) or fulvic (FA) acids extracted from a peat soil. These humic substances have a higher carboxylic and nitrogenated character for HA, and a higher concentration of oxidized groups for FA, as determined by infrared (FTIR) and Raman spectroscopies. The corrosion tests showed that HA and FA enhance the pitting corrosion of the API 5LX65 steel. The observed pits are always ass
