Em que sentido(s) é radical o Behaviorismo Radical?

The use of the adjective radical to identify the variety of behaviorism proposed by Skinner is current nowadays. However, historically, this qualifier was not exclusively applied to Skinner's proposal and its polysemy tends to generate inaccuracies in the interpretation of what characterizes Skinner's Radical Behaviorism. This article aims to clarify the most appropriate sense of radical when applied to Skinner's behaviorism by means of four articulated activities: (1) the description of the etymological origins of the word radical and its different meanings in Portuguese, Spanish and English, (2) a reconstruction and analysis of the evolution of a historical setting that culminated in the use of the term in the behaviorist context, (3) an analysis of the main meanings of radical when associated with behaviorism, (4) an examination of some ways in which the use of the term associated with behaviorism is consistent, and the current and future implications for Radical Behaviorism and Behavior Analysis in a scientific context.

Electrochemical kinetic study of surface layer growth on natural pyrite in acid medium

This paper presents electrochemical experiments on natural pyrite that combine potentiostatic and voltammetric techniques. X-ray microanalysis is used as an auxiliary technique. The layer growth on pyrite surface is conducted in a wide range of pH and potential range: 3.4 <= pH <= 5.9 with E = 0.80 V (versus SHE), and 0.80 V <= E <= 1.00 V with pH 4.5 (versus SHE) in acetic acid-acetate buffer. This work is unique for two reasons: (1) phenomenological model about layer growth is applied and mathematical-physic consistence is verified and (2) Meyer's hypotheses of chemical mechanism are used to explain kinetic parameters of the phenomenological model.

Zoneamento acústico urbano e mapeamento de níveis sonoros na zona central de Rio Claro (SP): diretrizes para o gerenciamento do ruído integrado ao planejamento ambiental urbano

Considering the growing degradation of the urban environmental quality resulting from the progressive sound pollution increase, as well as the consequent harmful effects about the human health, the present study had its central objective the argument and management tools implementation of the urban noise that can be integrated to the environmental planning in the city of Rio Claro (SP). Therefore, normative and bibliographical revisions were developed, that made feasible the directives of control argument and prevention of the urban noise, as well as the technical procedures of sound levels and evaluation’s definition and especially about the criteria applicable for the elaboration of an urban acoustic zoning methodology. Among the main results obtained detach: (1) the applicable legislation to the management of urban noise’s synthesis and argument; (2) the methodology of urban acoustic zoning development and (3) its implementation to determined areas of Rio Claro (SP) with the (4) respective cartography representation; (5) the mapping of sound levels in the central zone of Rio Claro (SP), (6) the obtaining and analysis of noise describers (LAeq, Lmáx, L10, L50, L90, Lmin and TNI) and the subsequent (7) acoustic maps elaboration for the main describers.

Implant-supported rehabilitation after treatment of atrophic mandibular fractures: report of two cases

Objective The objective of this article is to present options of rehabilitation with dental implants in two cases of severely atrophic mandibles (<10 mm) after rigid internal fixation of fractures. Patients and method Two patients who sustained fractures in severely atrophic mandibles with less than 10 mm of bone height were treated by open reduction and internal fixation through a transcervical access. Internal fixation was obtained with 2.4-mm locking reconstruction plates. The first patient presented satisfactory bone height at the area between the mental foramens and after 2 years, received flapless guided implants in the anterior mandible and an immediate protocol prosthesis. The second patient received a tent pole iliac crest autogenous graft after 2 years of fracture treatment and immediate implants. After 5 months, a protocol prosthesis was installed in the second patient. Results In both cases, the internal fixation followed AO principles for load-bearing osteosynthesis. Both prosthetic devices were Branemark protocol prosthesis. The mandibular reconstruction plates were not removed. Both patients are rehabilitated without complications and satisfied with esthetic and functional results. Conclusion With the current techniques of internal fixation, grafting, and guided implants, the treatment of atrophic mandible fractures can achieve very good results, which were previously not possible.

Effects of coronal leakage on concentration of hydrogen ions and calcium hydroxide release of several calcium hydroxide pastes over different periods of time

Purpose: To evaluate the effects of coronal leakage on concentration of hydrogen ions (pH) and calcium release of several calcium hydroxide pastes, over different periods of time. Material and Methods: Fifty extracted human mandibular central incisors (n=10) were instrumented up to the F2 instrument and assigned to the following intracanal dressing: G1- Calen, G2- Calen with 0.4% chlorhexidine (CHX), G3- Calcium hydroxide with camphorated paramonochlorophenol (CPMC) and glycerin, G4- Calen, but temporary filling material maintained during all test (positive control) and G5- Root canal without intracanal dressing (negative control). All groups were immersed in distilled water for 7 days. In sequence, the temporary filling materials were removed, except in controls groups. All specimens were individually mounted on a specific device and only its root again immersed in distilled water. Concentration of hydrogen ions and calcium release by calcium hydroxide pastes in distilled water were evaluated in 24h, 7, 14 and 28 days. The results were submitted to ANOVA test (p = 0.05). After 28 days, root canals from experimental groups were examined in SEM. Results: G1, G2, G3 and G4 presented similar pH values and calcium release and did not differ from each other (p>0.05), up to 7 days. After this time G1, G2 and G3 presented values lower values than G4 (p<0.05). In SEM analysis, calcium hydroxide residues were observed in all experimental groups. Conclusions: After 7 days, coronal leakage decreased the concentration of hydrogen ions and calcium ion release provided by all calcium hydroxide pastes.
