O tratamento probabilístico da teoria cinética de colisões em livros de química brasileiros para o ensino médio

This paper presents and discusses an analysis of the approaches and the didactic treatment of the kinetic model of collision between particles in chemical reaction (collision theory model) presented by brazilian chemistry textbooks for the medium level. Our starting point at this search was the correct and scientific model for this theory which is based on random events, but most of all the books investigated does not consider this fact like an important and very precious didactic aspect. We utilized in the investigation the writing discoursive analysis technique.

O lugar da psicanálise e a universidade

As a usual practice in society, psychotherapy is considered a normal procedure, but how does it take place in an investigation method of subjectivity in the university? The theory of speech of Lacan helps us to locate a place to psychoanalysis in the university as a language practice in the role of teaching, research and extension (community work). In this sense, the university submits the ideas of conscience to science and material rationality, excluding the individual and the unconscious. The theory of speech helps us to see the difference between the speech the students use and the speech the annalist uses in his practice. The psychoanalysis has its own knowledge based on the unconscious, due to the clinic work precedes as well as the work in university extension (community work). The work of the annalist has his particular world to treat his mane object — the unconscious.

The cone loading test to estimate deformability moduli of a tropical soil

The Cone Loading Test (CLT) consists of the execution of a load test on the piezocone probe in conjunction with the CPT test. The CLT yields the modulus ECLT, a parameter that can be used in the estimative of foundation settlement. It is also presented here the interpretation and the process to determine ECLT values from the stress-displacement curves obtained from cone loading tests. Several CLT tests were conducted at the experimental research site of São Paulo State University, Bauru-SP-Brazil. The geotechnical profile at the studied site is a brown to bright red slightly clayey fine sand, a tropical soil common to this region which is lateritic, unsaturated and collapsible. The results of CLT tests satisfactorily represent the behavior of the investigated soil. The penetrometric modulus ECLT for each depth was calculated considering the elastic behavior in the initial linear segment of the soil stress-strain curve. The ECLT moduli obtained for the various tests were compared to moduli obtained from PMT and DMT test results performed at same studied site. The shear modulus degradation curves obtained from the CLT tests are also presented. The comparison to PMT and DMT results indicates the CLT test is a viable complementary test to the CPT in the quest for better understanding stress-strain behavior of soils. Further, the CLT test provides a graphic visualization of the degradation of the shear modulus with increasing levels of strain. As a hybrid geotechnical test, CPT+CLT can be valuable in the investigation of non-conventional collapsible soils, whose literature lack reference parameters for the prediction of settlement in the design of foundations.

Gêneros e formatos da folkcomunicação

The study of Folk Communication is a major legacy of Luiz Beltrão in his endeavor to educate journalism students about collective communication and its many ramifications. The topicality of this pioneering research has piqued the interest of many groups, not only in Brazil but also in Latin America and in European countries. This research seeks to know, map, and organize the data on Folk Communication available on the web, dealing more specifically with Iconic Folk Communication, Funeral Format, and Kinetics Folk Communication, Format: Rite of Passage, as defined by Professor José Marques de Melo in his investigation on Genres and Formats of Folk Communication: a taxonomic approach. Employing bibliographic and documentary research, the objective of this analysis is to verify which types are present, and whether there are other formats and identify them.

Emprego do método eletromagnético (em) na investigação e mapeamento de contaminações geradas por cemitérios: o caso de Monte Alto/SP

The use of geophysical methods in the analysis and mapping of likely contamination plumes has shown a huge value in the development of researches related to environmental issues. Among the main geophysical methods applied to this purpose, the geoelectrical methods stand out, being based on the use of electric and electromagnetic fields. The electromagnetic method (EM) uses physical environment responses created by electromagnetic field propagation, consisting of an alternated electric output and a magnetization force, used to obtain the electric conductivity (σ) of the subsurface materials. It has a broad application in the mineral exploration and prospection, and its use has been also efficient in environmental researches. By the electromagnetic method, this work examined and mapped possible contaminations created by cemetery leachate in the Saudade's Cemetery, located in the city of Monte Alto, Sao Paulo, where sedimentary rocks of the Bauru Group are exposed. Cemetery leachate is a putrefactive liquid, generated from the decomposition of organic matter, which contains substances that can contaminate soil and groundwater. Results achieved in this work show that the use of the electromagnetic method is an important indirect tool in the investigation of environmental contaminations in areas with highly contrasting physical properties

The construction of the African perspective: a history of the General History of Africa project (Unesco)

This article analyzes the construction of the African perspective in the General History of Africa project (GHA), focusing on the period between 1965 and 1979. With the participation of over two hundred international experts under the auspices of Unesco, this was one of the greatest intellectual projects of the twentieth century. Based on primary sources, this analysis emphasizes the internal conflicts involved in the construction of the African perspective as a hegemonic line of thought in the GHA. Two critical moments of the project were found in the investigation: the controversial years (1972-78), and the pragmatic years (1978-82). As a result of these disputes, theoretical and methodological parameters were constructed, in addition to eight volumes of material published in the 1980s, and recently republished in Brazil.

Pure red cell aplasia and primary antiphospholipid syndrome: a unique association

Pure red cell aplasia (PRCA) is a disease with important relationships to autoimmune mechanisms. Although some autoimmune diseases, such as rheumatoid arthritis and systemic lupus erythematosus, have been associated with PRCA, until this point no studies have described the association between PRCA and primary antiphospholipid syndrome (APS). This is the first case report of PRCA associated with primary APS in a 39-year-old man with acute heart failure secondary to an anaemic condition that was diagnosed as pure red cell aplasia. The patient was later diagnosed with retinal artery and vein thromboses and bilateral deep venous thromboses of the femoral and popliteal veins. The most common causes of PRCA and other thrombophilias were ruled out in this investigation through complementary tests. This association with APS adds a new possibility to the study of PRCA pathophysiology.

Interaction of p-cymene with beta-cyclodextrin

In this investigation, the study of inclusion complexes formation between p-cymene and beta-cyclodextrin using the methods of physical mixture, paste (PC) and slurry (SC), was evaluated. The results of DSC and TG/DTG showed that the products prepared by PC and SC methods were able to incorporate greater amounts of p-cymene, as evidenced by the weight loss of 7.15 and 3.97%, respectively, which occurred between 120 and 270 A degrees C. SEM images showed decreased size of the household, especially in the SC product. The absorption bands in the IR spectrum, characteristic of p-cymene, were also identified in the preparations, indicating the presence of the compound in the complex.

The effects of the pressing step on the microstructure and aging of NdFeB bonded magnets

The effects of the compaction step on the (micro)structural features and aging behavior of polymer coated NdFeB-based bonded magnets is reported. Due to the fracture of the material during pressing, it is estimated an increase of at least 14% in the particles' area which is not coated. Such uncoated surfaces, when exposed to the environment, reduce the magnetic performance of the magnets aged/cured in air by 19% in the conditions evaluated in this investigation. Furthermore, XRD results interpreted by Rietveld analyses show a lattice parameter change in the tetragonal structure of the hard magnetic phase after pressing. Such change varies as a function of the height of the compacted part and it is ascribed to macro-elastic stress arising from the pressure distribution in the magnet. An aging/curing step during 24 h is able to relief such macro-elastic stress. (C) 2012 Elsevier B.V. All rights reserved.
