title: Financial cycles and the credit market in Brazil during the 2000s

description: Abstract This study aims to analyze the behavior of Brazilian state-owned banks during the global financial crisis and its aftermath. In this regard, it employs time-series econometrics, based on the MS-DR and VEC models. Evidence was found suggesting that the credit originated in state-owned banks showed counter-cyclical characteristics; while private banks behaved in a typically procyclical manner.

title: Citric acid production by Aspergillus niger AN 400 from agroindustry waste

description: ABSTRACT The agro-industry generates large volumes of waste with high organic load, which requires the development of technologies to minimize the impacts caused by the improper disposal of this waste on the environment. The citric acid produced by agro food wastes as substrate for fermentation is a solution to reduce the organic load of these pollutants and add economic value by generating a profitable product. Aspergillus niger AN 400 was used to produce citric acid from cheese whey. The study was divided in three phases according to the addition of extra sugar (50, 100, 150 g.L-1): Phase I, with glucose; Phase II, with sucrose, and Phase III, with cheese whey only, without adding extra sugar. The reactors remained under agitation 150 rpm and at 30ºC for 10 days. The highest concentration of citric acid (2,379 mg.L-1) was observed upon the addition of 100 g.L-1 of glucose. However, the greatest yields were recorded in the reactors with 50 (458 mg.L-1.day-1) and 100 g.L-1 (745 mg.L-1. day-1) of sucrose, followed by the reactor that contained only cheese whey, without adding extra sugar (313 mg.L-1.day-1), demonstrating the potential of this waste to obtain citric acid with a great commercial interest.

title: Water safety plan implemented on Guaraú water treatment plant in São Paulo, Brazil

description: ABSTRACT Water Safety Plans represent the strategy for predicting hazards and monitoring risks that can threat the water quality for human consumption. This paper intended to study Water Safety Plans implemented at Guaraú water treatment plant in order to identify its methodological requirements, challenges and opportunities for the effective control in water supply systems. The documents that supported the plan were the World Health Organization recommendations and the drinking water standards of Brazilian regulation 2914/2010 by Health Ministry. Regarding water treatment, the managers of sanitation in the metropolitan areaof São Paulo adopted Beuken et al. (2008) and Brazil (2012) methodologies for hazard description and risk evaluation. This evaluation model proposes that the greater value associated to a certain parameter meansit needs more attentionthan another in the water supply system. The company has implemented Water Safety Plans to optimize its treatment processes and to ensure water distribution with quality and efficiency. The company has been discussing about this tool since 2006; it identified a methodology that could express the environmental policy guidelines, elaborated a model of Water Safety Plans, held technical meetings and applied the plan to Guaraú water treatment plant. The main results were records systematization, implementation of new procedures, acquisition of equipment, technical capacitation and identification of control points. The greatest challenge was to establish a feasible and dynamic preventive tool for managing water resources. It must be emphasized that the Water Safety Plans success depends on, among other variables, an up-to-date database, the cooperation of decision-makers and continuous adjustments required by the methodology itself. There is not sufficient scientific studies and handbooks about this subject.

title: The Research-Action on the continued formation in Environmental Education for Math teachers

description: ABSTRACT This paper, part of a doctoral research, presents and analyses the implications of a continued formation in environmental and math education based on the assumptions of a “Research-Action” qualitative research. The formation performed involved eight math teachers from final grades of state and municipal elementary schools of São Sebastião do Caí, state of Rio Grande do Sul, Brazil. The procedures used in this formation followed the steps of planning, action, observation and reflection for decision making. This paper is mainly grounded on the ideas of Carvalho (2001), Jacobi (2005), Sorrentino (2001), Castro (2001), Penteado (2010), Behrens (1996), Thiollent (1985, 1998). According to the collected data, we notice that the formation developed gave theoretical-practical subsidies for teachers to perform classroom activities promoting the development of environmental awareness within the ones involved in the educational process. And also, throughout the development of the environmental-themed activities in class, the teachers were able to contextualize math, approaching it to the local students’ reality.

title: Hormone treatment as first line therapy is safe and relieves pelvic pain in women with bowel endometriosis

description: ABSTRACT Objective: To evaluate clinical features and complications in patients with bowel endometriosis submitted to hormonal therapy. Methods: Retrospective study based on data extracted from medical records of 238 women with recto-sigmoid endometriosis treated between May 2010 and May 2016. Results: Over the course of follow-up, 143 (60.1%) women remained in medical treatment while 95 (39.9%) presented with worsening of pain symptoms or intestinal lesion growth (failure of medical treatment group), with surgical resection performed in 54 cases. Women in the Medical Treatment Group were older (40.5±5.1 years versus 37.3±5.8 years; p&lt;0.0001) and had smaller recto sigmoid lesions (2.1±1.9 versus 3.1±2.2; p=0.008) compared to those who had failed to respond to medical treatment. Similar significant reduction in pain scores for dysmenorrhea, chronic pelvic pain, cyclic dyschezia and dysuria was observed in both groups; however greater reduction in pain scores for dyspareunia was noted in the Surgical Group. Subjective improvement in pain symptoms was also similar between groups (100% versus 98.2%; p=0.18). Major complications rates were higher in the Surgical Group (9.2% versus 0.6%; p=0.001). Conclusion: Patients with recto-sigmoid endometriosis who failed to respond to medical treatment were younger and had larger intestinal lesions. Hormonal therapy was equally efficient in improving pain symptoms other than dyspareunia compared to surgery, and was associated with lower complication rates in women with recto-sigmoid endometriosis. Medical treatment should be offered as a first-line therapy for patients with bowel endometriosis. Surgical treatment should be reserved for patients with pain symptoms unresponsive to hormonal therapy, lesion growth or suspected intestinal subocclusion.

title: Low cost optical spectroscopy: a strategy to introduce quantum physics concepts in high school

description: Abstract In this paper, we report the production and discuss the applicability of a low cost optical spectrometer as a didactic resource for the introduction of Quantum Physics concepts in high school. The prototype was developed using commercial diffraction grating, convergent lenses (magnifying glass), webcam and the software Tracker for data extraction. Emission spectra of light sources, such as fluorescent lamps, LEDs and lasers, were collected and their potentialities to support the introduction of the concepts of electronic levels, band gap energy, emission and absorption of photons, etc., were explored. We also propose an experimental activity based on LED photoexcitation to treat the relationship between photon energy and its wavelength. In addition, we showed that the prototype can be satisfactorily used to obtain absorption spectra, which can be used as a motivating element for the study of the interaction between radiation and matter. Finally, in the light of the results obtained, we discussed the application of optical spectroscopy as a strategy to reach the recommendations of the Brazilian National Curricular Parameters regarding the insertion of Quantum Physics in basic education.

title: Rediscovering Hubble's empirical law in the classroom

description: Abstract The 20th century witnessed two great cosmological discoveries: The Cosmic Background Radiation corresponding to a black body temperature T = 2.275 K, and the expansion of the universe expressed by the cosmological version of Hubble's empirical law of 1929. In this paper we propose a pedagogical reconstruction in class of the original Hubble's law with a hands-on approach making use of modern resources freely available on the web.

title: Subordination strategies in Tupian languages

description: Abstract: Assessing the internal coherence and constituency of language families often centers either around comparing certain form-meaning correspondences, or around identifying the presence or absence of linguistic features across the members of the family. The former approach is generally restricted to the lexicon. The latter approach focuses mostly on structural characteristics of language. In this paper we present an alternative approach to comparing grammatical systems between languages within a language family, which aims at bringing these two approaches and their results closer to each other. We look at subordination strategies in a sample of Tupian languages, taking constructions as the basic unit of comparison, treating them as form-meaning correspondences. The Tupian family offers an especially intriguing case for studying subordination strategies in the South American context, given its enormous geographical spread and the variety of contact situations involving its member languages. Major patterns of subordination strategies can be discerned across the family, e.g. strategies involving nominalization, verbal incorporation and other subtypes of verbal serialization, but there is also a great degree of variability between the different languages. By mapping the structural diversity onto the known genealogy and geographic distribution, we hope to shed more light on the history of the Tupian family and on the diffusability of subordination strategies.

title: TRANSLATING THE IDENTITY OF BRAZILIAN FAVELA IN FRANCE: JE SUIS FAVELA/EU SOU FAVELA

description: ABSTRACT Eu sou favela (2012) is a collection of short stories written by Brazilian writers who narrate stories set in slums. Its translation, Je suis favela (2011), was made available by Éditions Anacaona, a French publisher that offers translations of Brazilian fiction less known to the French and Brazilian public and which portrays sociocultural aspects of Brazil. In the source-text there is a more colloquial register that was meant to successfully render the identities of the characters. We verified the ways in which the translation of one of the short stories, entitled "J'suis qu'un ouf" ("A.B.C." in Portuguese), has resorted to orality markers in French, and how it has contributed to the creation of characters' identities in the target-text. In order to do so, we have drawn on Crépon (2004), Rodrigues (2008) and Amorim (2015), especially regarding the debates on the concept of translation itself, translation as a form of writing that consolidates noncanonical literatures and, consequently, identity issues underlying the process. We also refer to Britto (2012) and Bagno (2012) regarding to the written representation of orality.

title: Prospective randomized trial comparing radiofrequency ablation and complete saphenous vein stripping in patients with mild to moderate chronic venous disease with a 3-year follow-up

description: ABSTRACT Objective: To compare the use of the radiofrequency thermoablation of the saphenous vein with the ligation technique, and complete removal of the saphenous vein, from the saphenofemoral junction to the ankle. Methods: A total of 49 patients with chronic venous disease in the Comprehensive Classification System for Chronic Venous Disorders (CEAP) classes 2 to 4 for clinical signs, etiology, anatomic distribution and pathophysiology, were assessed at baseline, after 4 weeks, and after 1 year. The parameters assessed were complications, period of absence from activities, Venous Clinical Severity Score (VCSS) and quality of life scores according to Aberdeen Varicose Veins Questionnaire (AVVQ). They were re-examined 1 and 3 years after treatment to evaluate recurrence rates. Results: The success rate per limb (p=0.540), VCSS (p=0.636), AVVQ (p=0.163), and clinical complications were similar in the two treatment groups. Nevertheless, the radiofrequency thermoablation group had significant shorter length of hospital stay (0.69±0.47) and absence from activities (8.62±4.53), p&lt;000.1. Conclusion: Patients submitted to radiofrequency thermoablation had an occlusion rate, clinical recurrence and improvement in quality of life comparable to removal of the saphenous vein. However, these patients spent less time hospitalized and away from their daily activities during recovering.

title: Collecting art and anthropology: controversies in the museums of Barcelona

description: Abstract This work aims to cover events that have surrounded museologists, anthropologists and art historians at least in the last five years in Barcelona. It tries to follow the after-effects of the reclassification of the “exotic art” Folch Collection and the consequences of its exhibition in two museums in town. The stories, facts, news, documents and decisions presented here were collected primarily from interviews with the professionals involved. They told in their own way the sequence of occurrences that triggered disputes around the concepts of “art” and “anthropology” when attributed to collections. We propose, therefore, to follow these events in order to discuss the recent changes in the field of ethnographic museums.
