Eça de Queirós e seu texto de imprensa 'Tema para versos I e II' (02 e 03/04/1893-Gazeta de Notícias): considerações

Eça de Queirós published in Gazeta de Notícias, the text “Theme for verses I and II” in April 2nd and 3rd in 1893 . From part II, it was taken an excerpt and published as a short story under the title “The maid” when this text was a part of the book Short Stories (12 stories, some of them handwritten, from 1874 to 1897) gathered by his friend, Luís de Magalhães, and published in 1903, under the year of 1902. Since then, the text ”The maid” is present in many editons of Eça de Queirós’ short stories without any mention to its primary source, the newspaper Gazeta de Notícias (Rio de Janeiro), or even the other part of the text in which it was originally in. The objective of these short considerations is reflecting if the short story, known as “The maid”, should be read as an excerpt of the original text as it has been done since 1902, or it should be put in its original context, joining the two parts of the text “Theme for verses I and II”.

Diel variation in abundance and size of the seabob shrimp Xiphopenaeus kroyeri in the Ubatuba region, Southeastern Brazil

The objective of the present study was to analyze diel variation in the abundance and size of the seabob shrimp Xiphopenaeus kroyeri in the Ubatuba region, state of São Paulo, during the year 2000. In each season of the year, collections were made in the day and at night on 9 transects at depths ranging from 2 to 40 m. The estimated shrimp amount was of 28,878 individuals. Although the catch rate was higher during the day (15,853 shrimp), this did not differ significantly from the catch at night (13,025). The catch rate was higher in daytime on most transects, but was higher at night at locations where fine and very fine sand predominated. The majority of juveniles were caught during the day. The mean size (CL) was 14.43 ± 4.02 mm for day and 14.82 ± 4.28 mm for night samples, and the difference was significant (Student’s t-test, df = 2, 429, t = 2.27, p = 0.02). The largest individuals were caught during the night. None of the three models that have been proposed in the literature to account for differences in the diurnal catch pattern of penaeid species can be applied to X. kroyeri. Our results provide evidence that sediment type not only influenced the catch rate in the analyzed periods, but also determined which models might fit the behavior of this species.

Effect of the substitutional elements on the microstructure of the Ti-15Mo-Zr and Ti-15Zr-Mo systems alloys

Titanium alloys have excellent biocompatibility, and combined with their low elastic modulus, become more efficient when applied in orthopedic prostheses. Samples of Ti-15Mo-Zr and Ti-15Zr-Mo system alloys were prepared using an arc-melting furnace with argon atmosphere. The chemical quantitative analysis was performed using an optical emission spectrometer with inductively coupled plasma and thermal conductivity difference. The X-ray diffractograms, allied with optical microscopy, revealed the structure and microstructure of the samples. The mechanical analysis was evaluated by Vickers microhardness measurements. The structure and microstructure of alloys were sensitive to molybdenum and zirconium concentration, presenting α′, α″ and β phases. Molybdenum proved to have greater β-stabilizer action than zirconium. Microhardness was changed with addition of molybdenum and zirconium, having Ti-15Zr-10Mo (436 ± 2 HV) and Ti-15Mo-10Zr (378 ± 4 HV) the highest values in each system.
