title: “Essential in every school”: an incursion in the world of school objects

description: ABSTRACT This paper analyses sales catalogues of the Companhia Melhoramentos de São Paulo, a publishing house with relevant operation regarding the production and trading of a wide range of school objects. We aimed at examining the action of this company in the configuration of the material culture related to primary school in the first decades of the 20th century. Companhia Melhoramentos was created in 1890 and from 1915 it relocated its investments, from the initial focus on printing and binding books to the production and sales of various school materials, in order to support school practices, and, at the same time, trying to generate new needs for consumption, thus expanding its business in a context marked by the dissemination of primary school in São Paulo, Brazil. Based on the analysis of the publishing house’s catalogue and on the problematization of the potential of such material as sources for the research of school material culture, we intent at raising the artifacts destined to be used in the many disciplines of the school curriculum and to the practices that happened in school, hence capturing traces of the material dimension of childhood schooling.

title: THERMAL CONDUCTIVITY ENHANCEMENT OF AQUEOUS IONIC LIQUID AND NANOPARTICLE SUSPENSION

description: Abstract In the present study, the thermal conductivities of ionic liquid + water in the concentrations 0.1-0.6 %w/w and temperatures (302.5-337.9 K) are determined. The thermal conductivity of aqueous 1-butyl-3-methylimidazolium bromide declined with increasing concentration and temperature. A quadratic model is developed for predicting the thermal conductivity of aqueous ionic liquid using response surface methodology with R2 = 0.99. A two-layered feed forward back propagation neural network 2-10-1 is also modeled with mean square error, root means square and absolute average error percentage of 0.005, 0.071 and 2.684, respectively. The thermal conductivity of nanofluid (γ-Al2O3/water) is estimated and compared with the ionic liquid solution at the same concentration and temperature range. Thermal conductivity enhancement ratios of aqueous ionic liquids are found to be more than nanoparticle suspensions.

title: World Class University in the Latin American and Caribbean context: what the International Organizations say

description: ABSTRACT In this article we analyze what International Organizations and their experts say about the possibility of building and/or existence of the World Class Universities in Latin America and the Caribbean countries, with the objective of highlighting how the specificities of this model for those countries, that do not make up the dynamic axis of capital, are being outlined. Regarding this, we seek to understand the movement of this tendency from the places occupied by Latin American universities in the main international academic rankings. In methodological terms, bibliographical data and documentary analysis are used, considering that the research on the trends and manifestations of the World Class Universities presupposes the understanding of the historical and social totality.

title: For a history of school-related protoindustry in the Empire of Brazil: The Röhe & Irmãos Factory and their school-desks (1868-1883)

description: ABSTRACT This article elaborates the concept of school-related protoindustry in order to approach the early industrial experiences of furniture production for schools in the Empire of Brazil. Based on the hypothesis that it would be located between the craft production and the industrial production of school-related objects, in the classification of these modalities proposed by Juri Meda (2015), and using the analytical perspectives of microhistory (LEVI, 2009; REVEL, 1996; GINZBURG, 1989; 1991), this paper aimed at investigating it, in a first approach, based on the case study of the Röhe & Irmãos Factory and the school-desks manufactured by it between 1868 and 1883 in the Imperial Court.

title: ON THE SEMANTICS OF ‘DE VOLTA’: AN EXERCISE ON COUNTERDIRECTIONALITY

description: ABSTRACT: Within the framework of formal semantics and pragmatics of natural languages, the aim of this paper is to analyse the expression ‘de volta’ in Brazilian Portuguese, considering it as an event modifier of a particular type, a counterdirectional modifier. In order to do this, we develop our analysis using Neo-Davidsonian Event Semantics and the Semantics of Trajectories proposed by Zwarts (2005, 2008), allied to an analysis of event modifiers. First, we present the domain of counterdirectionality, its main distinctions and the proposal of Zwarts and Basso (2016), which also deals with Brazilian Portuguese. Next, we present several data related to the interpretations of ‘de volta’; in the following section, we develop our specific proposal for the semantic analysis of ‘de volta’. As a result, we propose a unified analysis of ‘de volta’ which accounts for its returnative, responsive, restitutive, and repetitive interpretations. We also present a review of the conclusions of Zwarts and Basso (2016) about ‘de volta’. We conclude this paper with some open issues.

title: Prevalence of peri-implant diseases – a critical review on the current evidence

description: Abstract The objective of this paper was to evaluate the current evidence reporting on the prevalence of peri-implantitis and to determine the influencing factors. An electronic search for articles published until February 2019 reporting on the prevalence of peri-implantitis was performed in MEDLINE. Included criteria were published in international peer-reviewed journals, written in English language, reported on the prevalence of peri-implantitis, included implants with a minimum follow-up of one year after functional loading and used a clear definition for peri-implantitis and/or peri-implant mucositis with a clear cutoff for bone level changes according to the case definitions of Sanz and Chapple and Berglundh et al. 2018. Included papers were anaylized for factors affecting the reported prevalences for peri-implantitis. Twenty-five papers were included in the present review and a wide range for the reported prevalence of peri-implantitis was seen. Case definitions for peri-implantitis with various thresholds for bone loss together with the type of reporting on patient- or implant-level were the most significant factors that lead to a large variety of the occurrence of the disease. Additionally, follow-up time and the evaluation in a certain “convenience” population may have influenced the prevalence values. In conclusion, it can be stated that a wide range for reporting the prevalence of peri-implantitis can be found and no real estimation of the global burden of the disease can be made. Applying accurate case definitions for peri-implantitis is the most important factor for reporting the prevalence and should be strictly followed in future reports.

title: Does knowledge about climate change imply adaptation? Analysis of farmers in Northeast Brazil

description: Abstract We analyze the relationship between farmer’s knowledge about climate change and the adoption of adaptive strategies. The study area was the Brazilian Northeast (Rio das Contas basin, Bahia). Methodologically, we estimated a Seemingly Unrelated Bivariate Probit model. The results showed that knowledge and adaptation are correlated and should be considered together. Farmers who are aware of the climate change effects are more likely to adapt. This finding reinforces the importance of considering the perception, knowledge and socioeconomic conditions of individuals in the formulation of public policies to counteract the negative effects of climate change.

title: OPTIMIZATION OF BIOFLOCCULANT PRODUCTION BY Bacillus spp. FROM SUGARCANE CROP SOIL OR FROM SLUDGE OF THE AGROINDUSTRIAL EFFLUENT

description: Abstract Biological flocculants are advantageous due to their biodegradability and safety to living beings. In this work, four bacterial strains, isolated from sugarcane cropped soil (Bacillus megaterium LBPMA-APFSG3Isox and B. toyonensis LBPMA-ACOPR1.Isox) and sludge of an agroindustrial effluent (B. pumilus LBPMA-BLD07 and B. thuringiensis LBPMA-EFIII), were studied. It was found that all of them secreted bioflocculants, at 37 ± 1 °C, with no pH changes over time and the flocculant activity increased during the time course of incubation. These results stimulated the optimization of the culture conditions to improve flocculation rates, such as the pH, nitrogen sources and carbon. For B. toyonensis LBPMA-ACOPR1.Isox and B. thuringiensis LBPMA-EFIII, the best pH for the bioflocculant production was 5.0. Sucrose and maltose were the best sources of carbon, while urea was the preferred source of nitrogen for two of the tested isolates (B. pumilus LBPMA-BLD07 and B. toyonensis LBPMA-ACOPR1.Isox), followed by (NH4)2SO4 (B. megaterium LBPMA-APFSG3Isox) and peptone (B. thuringiensis LBPMA-EFIII). The FTIR-ATR spectra of each extracted material responsible for the flocculant activities of the strains displayed carboxyl, hydroxyl and methoxy functional groups characteristic of polysaccharides.

title: An umbrella review on the effects of diabetes on implant failure and peri-implant diseases

description: Abstract The aim of this review is to summarize the evidence on associations between diabetes mellitus (DM) and complications around dental implants. Electronic database searches of MEDLINE, EMBASE, JBI Database of Systematic Reviews and Implementation Reports, Cochrane Database of Systematic Reviews and the PROSPERO register were performed from 1990 up to and including May 2018, using MeSH terms and other keywords. Systematic reviews and meta-analyses investigating the associations of DM and implant complications (failure, survival, bone loss, peri-implant diseases, and post-surgery infection) were eligible. The quality of the included reviews was determined using the Assessment of Multiple Systematic Reviews Tool 2 (AMSTAR 2). Twelve systematic reviews were included. Implant survival rates ranged from 83.5% to 100%, while implant failure rates varied from 0% to 14.3% for subjects with DM. The three meta-analyses performed for event “implant failure” reported no statistically significant differences between diabetic and non-diabetic subjects. An apparently increased risk of peri-implantitis is reported in patients with DM. According to the AMSTAR 2 classification, 50% of the reviews were classified as being of “critically low”, 25% as of “low” and 25% as of “moderate” quality. Evidence indicates high levels of survival and low levels of failure of implants inserted in patients with DM. However, DM was assessed as a whole in the majority of studies and, the actual influence of hyperglycemia on implant survival/failure is still uncertain. DM/hyperglycemia seems to be associated with a high risk of peri-implantitis. However, this conclusion is based on a limited number of systematic reviews.

title: Does traumatic occlusal forces lead to peri-implant bone loss? A systematic review

description: Abstract Observational studies have indicated that crestal bone level changes at implants are typically associated with clinical signs of inflammation, but still mechanical overload has been described as possible factor leading to hard–tissue deficiencies at implant sites without mucosal inflammation. The aim of this paper was systematically review the literature regarding the possible effect of traumatic occlusal forces on the peri-implant bone levels. Literature search was conducted using PubMed, Scielo and Lilacs, including the following terms: oral OR dental AND implant$ AND (load OR overload OR excessive load OR force$ OR bruxism) AND (bone loss OR bone resorption OR implant failure$). Databases were searched for the past 10 years of publications, including: clinical human studies, either randomized or not, cohort studies, case control studies, case series and animal research. Exclusion criteria were review articles, guidelines and in vitro and in silico (finite element analysis) research, as well as retrospective studies. The PICO questions formulated was: “does traumatic occlusal forces lead to peri-implant bone loss?” The database searches as well as additional hand searching, resulted in 807 potentially relevant titles. After inclusion/exclusion criteria assessment 2 clinical and 4 animal studies were considered relevant to the topic. The included animal studies did not reveal an association between overload and peri-implant bone loss when lower overloads were applied, whereas in the presence of excessive overload it seemed to generate peri-implant bone loss, even in the absence of inflammation. The effect of traumatic occlusal forces in peri-implant bone loss is poorly reported and provides little evidence to support a cause-and-effect relationship in humans, considering the strength of a clinically relevant traumatic occlusal force.

title: CHARACTERIZATION-PERFORMANCE OF ZnO AND ZnO/ZnFe2O4 CATALYST USING ARTIFICIAL AND SOLAR LIGHT FOR MERCURY (II) REDUCTION

description: Abstract This study describes the application of ZnO commercial oxide and ZnO/ZnFe2O4 mixed oxides to reduce the mercury ion (Hg2+) in the aqueous phase. The catalysts synthesized were characterized by thermogravimetric analysis, adsorption and desorption of N2, scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, photoacoustic spectroscopy and Mössbauer spectroscopy. The heterogeneous photocatalysis process was studied in synthetic effluent treatment containing mercury chloride (HgCl2) in a batch and solar reactor. The results indicated that commercial ZnO catalyst totally reduced the Hg (II), in all conditions and reaction systems studied. On the other hand, for the mixed oxides (ZnO/ZnFe2O4), there was a decrease in the reduction efficiency in the batch reactor, indicating no ability to reduce Hg(II) in the presence of sunlight.
