Effect of thermal modification on the physical properties of juvenile and mature woods of Eucalyptus grandis

This study aimed to evaluate the effect of thermal treatment on the physical properties of juvenile and mature woods of Eucalyptus grandis. Boards were taken from 30-year-old E. grandis trees. The boards were thermally modified at 180 °C in the Laboratory of Wood Drying and Preservation at UNESP, Botucatu, Sao Paulo state, Brazil. The results showed that thermal modification caused: (1) decrease of 6.8% in the density at 0% equilibrium moisture content of mature wood; (2) significant decreases of 14.7% and 35.6% in the maximum volumetric swellings of juvenile and mature woods, respectively; (3) significant decreases of 13.7% and 21.3% in the equilibrium moisture content of juvenile and mature woods, respectively. The influence of thermal modification in juvenile wood was lower than in mature wood and caused greater uniformity in the physical variations between these types of wood in E. grandis.

Curso de pedagogia da Faculdade de Educação da Universidade de Salamanca/Espanha (2010): uma chave para reflexões

This was part of the post-doctorate study developed at the Faculty of Eucation in the University of Salamanca - Spain in 2010 with the Professor José Maria Hernández Díaz, who teaches the subject “History of Education” at the Pedagogy course provided by the institution. The objective of this reflection is to present some characteristics of that course, in order to highlight some of its peculiarities, and also indicate some similar issues when compared to Brazilian courses, thus producing a research useful for comparison and deepening of teacher’s training. The method was based on quali-quantitative nature (WOODS, 1996; BESSON, 1995): participant observation (EZPELETA; ROCKWELL, 1986; KETELE; ROEGIERS, 1993) and a questionnaire application (HEGENBERG, 1976; BOOTH; COLOMB; WILLIAMS, 1995) to the first and third classes in 2010, which resulted in a total of 99 students: 17 male and 82 female. This comparative information evinces the feminisation in that course, establishing direct relationship with Brazilian research. Another data, which has not yet been duly checked in Brazil, concerns the intellectual/social role of women in the classroom. Although this data is especific from that school environment, it is an important key-point for teachers’ training and teaching. The potentiality of this reflexition is exactly on this point.

A contratransferência e a importância das capacidades do analista na prática psicanalítica contemporânea

Although the use of countertransference is a controversial topic and the debate on the participation of the analyst’s mind may go back to the old conception of aptness for the analytical task based on personality or psychological makeup, the fact is that the psychoanalyst’s education involves the elaboration of his unconscious conflicts, turning conscious the pathways of his desire and his symptoms through a process of personal analysis and a long theoretical and technical training in the field of psychoanalysis. This study is a literature review based on studies about the maternal function, which aims at showing the path of recovery of countertransference in psychoanalytic theory and technique and the implication of the analyst’s abilities in the analytical process. This development is tributary of the appreciation of maternal function as a model for interpersonal and therapeutic relationship in Psychoanalysis, due to the paradigm of object relations in the British psychoanalytic tradition, being Donald W. Winnicott and Wilfred R. Bion two of its main authors.

EFFECTS OF IMPLEMENTING EPA'S ENDANGERED SPECIES PROTECTION PROGRAM ON NATIONAL FOREST SYSTEM LANDS

In 1986, the U.S. Environmental Protection Agency (EPA) initiated an effort to comply more fully with the Endangered Species Act. This effort became their "Endangered Species Protection Program." The possibility of such a program was forecast in 1982 when Donald A. Spencer gave a presentation to the Tenth Vertebrate Pest Conference on "Vertebrate Pest Management and Changing Times." This paper focuses on current plans for implementing the EPA's Endangered Species Protection Program as it relates to the USDA Forest Service. It analyzes the potential effects this program will have on the agency, using the pocket gopher (Thomomys spp.), strychnine, and the grizzly bear (Ursus arctos horribilis) as examples of an affected pest, pesticide, and predator.

XMM-Newton EPIC and OM observation of Nova Centauri 1986 (V842 Cen)

We report the results from the temporal and spectral analysis of an XMMNewton observation of Nova Centauri 1986 (V842 Cen). We detect a period at 3.51 +/- 0.4 h in the EPIC data and at 4.0 +/- 0.8 h in the Optical Monitor (OM) data. The X-ray spectrum is consistent with the emission from an absorbed thin thermal plasma with a temperature distribution given by an isobaric cooling flow. The maximum temperature of the cooling flow model is keV. Such a high temperature can be reached in a shocked region and, given the periodicity detected, most likely arises in a magnetically channelled accretion flow characteristic of intermediate polars. The pulsed fraction of the 3.51-h modulation decreases with energy as observed in the X-ray light curves of magnetic cataclysmic variables, possibly due either to occultation of the accretion column by the white dwarf body or phase-dependent to absorption. We do not find the 57-s white dwarf spin period, with a pulse amplitude of 4 mmag, reported by Woudt et al. in either the OM data, which are sensitive to pulse amplitudes ?0.03 mag, or the EPIC data, sensitive to pulse fractions p? 14 +/- 2 per cent.
