Wetland projects developed in Brazil

The first studies with constructed wetlands undertaken in Brazil were the result of observations made from the Amazon flood plains. The first attempt to use this capacity to change the quality of the water, in the sense of purification performed in Brazil using constructed wetland systems, was made by Salati et al. After that, new technologies were developed in a focused attempt to increase the efficiency of the system and reduce investments. Over these 18 years, persuading the Brazilian scientific community as well as the environmental control agencies to give due attention to this kind of research has required endless efforts. Only in recent years have major institutions responsible for sewage treatment and potable water supply been concerned with this type of technology for solving real problems. These institutions are as follows: SABESP (Basic Sanitation Company of Sao Paulo State), SANEPAR (Sanitation Company of Parana State) and CESP (Electric Company of Sao Paulo State). One of the private institutions that has systematically worked in the design and projects of constructed wetlands is the Institute of Applied Ecology. This institution has enhanced and developed a water depuration system based on the purifying capacity of the soil. The wetlands with filtering soils are systems formed by overlapping layers of crushed stone, gravel and soil planted with rice. This technology has been used in sewage treatment and also in water supply systems.

Length of resin tags in pit-and-fissure sealants: all-in-one self-etching adhesive vs phosphoric acid etching.

PURPOSE: To investigate the penetration (tags) of adhesive materials into enamel etched with phosphoric acid or treated with a self-etching adhesive, before application of a pit-and-fissure sealant. MATERIALS AND METHODS: The sample comprised six study groups with six specimens each. Before pit-and-fissure sealing with the materials Clinpro SealantTM (Groups I and II), Vitro Seal ALPHA (Groups III and IV) and Fuji II LC (Groups V and VI), the teeth in Groups I, III, and V were etched with 35% phosphoric acid for 30 seconds. Teeth in Groups II, IV, and VI received application of the self-etching adhesive Adper Prompt L-Pop. The treated teeth were sectioned buccolingually, ground to 100-microm thickness, decalcified, and analyzed by conventional light microscopy at 400x magnification. RESULTS: The teeth etched with phosphoric acid exhibited significantly greater penetration than specimens treated with self-etching adhesive. CLINICAL SIGNIFICANCE: When compared with enamel treated with a self-etching adhesive, the penetration (tags) of adhesive materials into enamel was greater when applied on enamel etched with phosphoric acid.

Buffalo milk production in brazil and colombia: Genotype by environment interaction

The objective of this study was to determine whether there is a genotype by environment interaction (GxE) for dairy buffaloes in Brazil and Colombia. The (co)variance components were estimated by using a bi-trait repeatability animal model with the REML method. Each trait consisted in the milk yield obtained in both countries. Contemporary group (herd, year and season of parity) and age at parity (linear and quadratic covariate) fixed effects, along with the additive genetic, permanent environment, and the residual random effects were included in the model. Genetic, permanent environmental and residual variance and heritabilities were different for both countries. The genetic correlations for milk yield between Brazil and Colombia were low (between 0.10 and 0.13), indicating a GxE interaction between both countries. Knowing that this interaction influences the genetic progress of buffalo populations in Brazil and Colombia, we recommend choosing sires tested in the country they will be used, along with conducting joint genetic evaluations that consider GxE interaction effects.

Translating passive revolution in Brazil

This article sets out to examine Antonio Gramsci's use of the concept of passive revolution and thereby 'translate' it to an alternative historical and contemporary context. If we can observe Gramsci as a 'translator' of Lenin, from Russia to Italy, we can also try to 'translate' Gramsci beyond his original circumstances to alternative conditions, hence the aim of translating Gramsci and his category of passive revolution in order to apprehend some aspects of the particularity of bourgeois revolution in Brazil. The thesis is that the theory and condition of passive revolution in Brazil has unfolded as a hybridism of liberal corporatism, which reveals the slow assumption of bourgeois rule as a form of supremacy. Importantly, the role of the military in this long process is also highlighted. © The Author(s) 2012.

Development of an analytical method for the quantification of pfaffic acid in Brazilian ginseng (Hebanthe eriantha)

Hebanthe eriantha (Poir.) Pedersen (Amaranthaceae), which is known as Brazilian ginseng is widely used in folk medicine as an aphrodisiac and antidiabetic tonic. The anti-tumor activity, attributed to the pfaffic acid present in roots of H. eriantha, is responsible for the great interest in the commercialization of this species. In Brazil, the species H. eriantha is mainly used in commercial preparations, although other plants of the genus Pfaffia and Hebanthe have been marketed as Pfaffia paniculata or Brazilian ginseng. The pfaffic acid present in the roots is mainly conjugated with sugars (pfaffosides) and can be used as an active marker of H. eriantha, which helps to differentiate this species from others marketed as Brazilian ginseng. The main objective of this study was to develop and validate a liquid chromatographic method to quantify pfaffic acid in the roots of H. eriantha. The extraction and hydrolysis conditions were optimized using an univariate and experimental design, respectively, and the quantification of pfaffic acid by high performance liquid chromatography with diode-array detection (HPLC-DAD) was validated. This method was used to evaluate the pfaffic acid content in 30 different genotypes of the species from a germplasm collection. The content of pfaffic acid ranged from 0.97 to 4.29% (w/w) on a dry weight basis. © 2013 Elsevier B.V.

Green supply chain management in local and multinational high-tech companies located in Brazil

The objective of this article is to analyse how green supply chain management (GSCM) practices are being adopted by some high-tech companies located in Brazil. The research was conducted using the case study approach, focusing on eight companies that are representative of this sector. The main results are: (a) the most adopted GSCM practices in the studied high-tech companies located in Brazil are internal environmental management, investment recovery and reverse logistics and (b) Brazilian environmental legislation and international policies are very important in driving the adoption of GSCM practices. The internationalisation of companies was also found to be a variable that interferes with the adoption of GSCM practices. This is one of the first studies that examine the relationship between GSCM and the internationalisation of companies located in Brazil. © 2013 Springer-Verlag London.

Use of psychoactive substances in students at a public university

Introduction: The use of psychoactive substances by the student population has been the object of various studies in Brazil. Objective: To determine the prevalence of substance use among students. Methods: Quantitative study with a closed questionnaire based on standardized assessment instruments was developed. It consists of questions related to types of psychoactive substance use, abuse, frequency and duration of use, self-criticism regarding the use, consequences of use in relation to health, and misdemeanors committed under the influence of psychoactive substances. The sample included the participation of 268 students. A total of 183 (68.3%) questionnaires were analyzed, and only those with positive result for substance abuse at some point in life, the remainder, 85 (31%) questionnaires, had negative responses to psychoactive substances. Results: Students’ responses to the two years surveyed indicated that the first psychoactive substance used was alcohol (77.9%), followed by tobacco use (10.9%), and marijuana (7.6%). Of the students surveyed, 145 (79.2%) answered that still make use of psychoactive substances, and the current frequency of use varies from one or more times per week. When asked about the possibility of being or becoming drug addicts, 169 (92.3%) responded that they are not or will not become dependent. Conclusion: The results indicate the high rate of substance use among college students surveyed, and point to their contradiction to consider such psychoactive substances harmful to their health.

Incríveis legados da 'reforma universitária' de 1968

This article examines aspects of policies for higher education during the Brazilian civil-military dictatorship (1964-1985) and some of its legacies that persist in the decades of 1990 and 2000. The text was divided into two parts: the first one analyses the "university reform" of 1968 and its historical context; the second discusses how some features configure certain trend in policies for higher education, with traces maintained until today. Finally, this amazing continuity is evaluated through four axes of analysis – 1) Fragmentation of education and different access to the levels and stages of teaching; 2) Deformation of the inseparability of teaching, research and extension; 3) Privatization as official policy for higher education; 4) Authoritarianism and systematic repression in institutions of higher education – and it is supported the need to resist and be opposed to the dominant project of policy for higher education in Brazil.

Formação acadêmica inicial em educação física: perfis profissionais, objetivos e fluxos curriculares de uma instituição privada de ensino superior do interior do Estado de São Paulo

The present study represents a qualitative thesis, characterized as a case study, which uses the method of the present approach. In addressing the academic home in physical education, there is the constancy of the discussions regarding the curriculum and professional formatting. In view of the curriculum modifications to fit the new legislation, and the fact they are few studies related to private institutions that offer such courses, which offer even greater number of courses when compared to public institutions aimed to investigate and analyze the professional profiles, curricular goals and flows contained in the pedagogical projects of courses bachelor degree in physical education and a private institution of higher education of the State of São Paulo, as well as verifying the existence and adequacy of articulation to the institutional educational project and the institutional development plan. Compounding the literature review discussed the key historical facts relating to courses in physical education in our country, and its path to the current model. Also presented was the law of physical education courses in force in Brazil and some concepts about teaching course projects and their relationship to other institutional documents. Techniques were used to review and document analysis, with primary source documents of their own and other government institution. It found a lack of interest of some private institutions of higher education in official documents available for this type of research, which is bad since there are more courses offered by them compared to public institutions. As for the degree course for training teachers of physical education, found lack of specificity regarding the differentiation between content and the bachelor, which ends up deviating from the expectations contained in the course to the one presented in the curriculum. Thus, it becomes a need for greater collaboration of private institutions of higher education...
