1. Acetic acid production by the newly isolated Pseudomonas sp. CSJ-3
ABSTRACT A fermentative acetic acid producing strain, named CSJ-3, was isolated from sludge and identified as Pseudomonas sp. on the basis of 16S rRNA gene analysis. The effects of cultivation conditions on the production of acetic acid by Pseudomonas sp. CSJ-3 were investigated in batch fermentation, and the maximum yield of acetic acid reached up to 0.49 %

2. Effect of soil contaminated by diesel oil on the germination of seeds and the growth of Schinus terebinthifolius Raddi (Anacardiaceae) Seedlings
The effect of soil polluted by diesel oil on the germination of seeds and the growth of Schinus terebinthifolius Raddi seedlings was analyzed at different times after contamination of the soil. The experiments were conducted under greenhouse conditions, with four treatments and five repetitions. The four treatments included: soil contaminated 30 (T30), 90 (T

3. CRESCIMENTO DE Podocarpus lamberti Klotzsch ex Endl. EM DUAS REGIÕES FITOGEOGRÁFICAS NO ESTADO DO RIO GRANDE DO SUL / GROWTH OF THE Podocarpus lambertii Klotzch ex Endl. IN TWO PHYTO-GEOGRAPHICAL REGIONS IN RIO GRANDE DO SUL STATE
In order to study the growth and the relationship with environmental variables of Podocarpus lambertii Klotzsch ex Endl. in two phyto-geographical regions of Rio Grande do Sul state, over hill fields (São Francisco de Paula) and Central depression (São Sepé), four subjects were sampled in each place and went through an complete stern analysis. The results

4. Characterization of traveling ionospheric disturbances over low latitude brazilian region associated to Perkins plasma instability generated at medium latitudes / Caracterização de distúrbios ionosféricos propagantes na região de baixas latitudes no setor brasileiro associados à instabilidade de plasma Perkins gerada em médias latitudes
With ground based measurements of OI 630 nm emission, by using all-sky imaging system installed at Cachoeira Paulista, we investigated the occurrence of specific events of Medium Scale Traveling Ionospheric Disturbances (MSTIDs), which occurred during nights geomagnetically quiet. Probably, these disturbances are associated with Perkins plasma instability ge

5. Produção de Quitina e Quitosana em cultura submersa de Rhizopus arrhizus nos meios milhocina e sintético para Mucolares
Inquiries had been carried out with submerged fermentation of Rhizopus arrhizus for production of biomass and copolymers chitin and chitosan, using the culture in synthetic medium for Mucoralean and corn steep liquor, as alternative substratum. In this direction, fermentations in Erlenmyers flasks of 250mL had been carried out, contend 50 mL of the media had

6. EFEITO DO TREINAMENTO AERÓBICO E ANAERÓBICO SOBRE AS CONCENTRAÇÕES DO HORMÔNIO DO CRESCIMENTO EM RATOS SUBMETIDOS A EXERCÍCIO FÍSICO
Generally, all the functions of the human body and the vertebrate ones as well, are controlled by the nervous and endocrine system that work on an integrated form, providing stability to the internal and external environment of the body, through the various homeostatic mechanisms. The general aim of this work was to verify the effects of different types of p

7. Efeito da deformação cíclica nas propriedades mecânicas de uma liga níquel-titânio superelástica
The effect of cyclic rotary bending strains on martensitic and reverse transformation temperatures, on mechanical properties and on recovery strain capacity, was investigated in this work, using wires of a superelastic NiTi alloy with 1.0mm in diameter. The influence of rotational speed on the materials fatigue resistance was analyzed as well. The material w

8. Improvement of lipase production at different stirring speeds and oxygen levels
Lipase production by a Brazilian wild strain of Yarrowia lipolytica at different stirring speeds and air flow rates was studied. The relationship among lipid consumption, cell growth and lipase production by this microorganism is presented. The most pronounced effect of oxygen on lipase production was determined by stirring speed. Maximum lipase activity was

9. Crescimento e caracterização de soluções sólidas óxidas. / Growth and caracterization of the oxides solid solutions.
Systematic growth experiments by flux method of the oxides solid solutions of GdAlO3:Cr3+ (perovskite type) were done with several solvents compositions. The doping (Cr3+) and solvent (Pb) concentrations profiles in selected samples, and the effetive segregations coefficient were determined and compared with those obtained by Czochralski method. Theoretical

10. Effect of Shaking Speed on the Secretion of Enterotoxin B by Staphylococcus aureus
The concentration of enterotoxin B secreted by four strains of Staphylococcus aureus was dependent upon the shaking speed. For the conditions established, each strain demonstrated an optimal shaking speed, and speeds in excess of the optimum resulted in decreased secretion of toxin. At the optimal shaking speed, maximum secretion occurred at 37 C. At 45 C, b

11. Multiple factors underlying the maximum motility of Escherichia coli as cultures enter post-exponential growth.
Motility and chemotaxis allow cells to move away from stressful microenvironments. Motility of Escherichia coli in batch cultures, as measured by cell swimming speed, was low in early-exponential-phase cells, peaked as the cells entered post-exponential phase, and declined into early stationary phase. Transcription from the flhB operon and synthesis of flage

12. Maximal Polar Growth Potential Depends on the Polarisome Component AgSpa2 in the Filamentous Fungus Ashbya gossypiiV⃞
We used actin staining and videomicroscopy to analyze the development from a spore to a young mycelium in the filamentous ascomycete Ashbya gossypii. The development starts with an initial isotropic growth phase followed by the emergence of germ tubes. The initial tip growth speed of 6–10 μm/h increases during early stages of development. This increase is
