Abstract The literature on the relationship between public policies, political parties, and presidential voting strongly focuses on analyses of income transfer programs, which limits the understanding of how different aspects of policy design and implementation relate to the partisan-electoral game. Through linear regressions applied to all Brazilian municipalities, this article analyzes the electoral dynamics of the Minha Casa Minha Vida (My House My Life) housing policy program. From the program’s inception to the 2014 elections, it details results by policy modalities, implementation phases, and adherence to the housing deficit. The results show that municipalities governed by parties belonging to the federal government’s coalition did not receive more housing units, except for the modality targeted at the poorest electorate. Moreover, the Worker’s Party’s (PT) electoral return was positive where the program’s implementation was related to the housing deficit, particularly in 2010. policies programs partisanelectoral partisan game Life program s 201 elections modalities phases deficit governments government units electorate Moreover Workers Worker Partys Party PT (PT 2010 20 2

Abstract This article presents the results of an ethnographic study on the experiences of gender-based violence of Aymara Bolivian women employed in agriculture or agricultural trade in the outskirts of Chilean territories of the Andean tri-border region. Our objective is to analyze the aggressions that women suffer in their family circles. We will analyze the narratives of 30 women to describe the aggressions perpetrated by the male figures in their families of origin (fathers, brothers, stepfathers), and their mothers. In addition, we will observe how these abuses are repeated in the relationships that they build with their partners and children. We will see a potential difference in violence between the Chilean and Bolivian border territories, and recognizing this difference motivates female cross-border mobility. The text seeks to contribute to the discussions on gender-based violence in border contexts. genderbased gender based triborder tri region circles 3 fathers, fathers (fathers brothers stepfathers, stepfathers , stepfathers) mothers addition children crossborder cross mobility contexts

Abstract This article intends to propose a methodology to characterize the Financial (In)Sustainability of Brazilian municipalities − materialized through the Municipal Financial Sustainability Index (ISFM) − as opposed to the methodology suggested by the Proposed Amendment to the Constitution (PEC) No. 188, whose agenda is to incorporate small municipalities considered unsustainable. Regarding the methods, we used quantitative, applied, descriptive and explanatory research, of the bibliographical and documentary type, in addition to descriptive statistics and correlation/linear regression. The results demonstrate that the ISFM is more robust compared to the methodology proposed by the PEC. The Index was applied to 5,570 Brazilian municipalities and the national average resulted in 56%. Most Brazilian municipalities classified themselves as “Sustainable” and the statistical analysis significantly demonstrated the existence of a positive correlation between the variables ISFM and Local Development. The contributions of the work turn to the production of research on the subject, still incipient nationally.

Abstract While early studies on electoral strategies argue that Brazilian system encourages “personal vote” and the creation of geographically located electoral strongholds, latest studies show that the most effective electoral strategy is vote dispersion. According to the contextual perspective, people vote for candidates whose political messages they have access to and who correspond to the demands of the places where they live. Based on the construction of a database regarding the legislative elections from 2010 to 2018 we seek to interpret the results found using this perspective. Starting from the hypothesis of a vote ruled by the way information is diffused in space, we find that most candidates have their strongest vote in their municipality’s electoral domicile, that those with only municipal experience show a voting pattern consistent with the “friends and neighbors” effect, and that there is a party coordination in the formation of candidate lists.Keywords: localism; electoral concentration; electoral strategies; electoral behaviour; electoral geography. personal strongholds dispersion perspective live 201 space municipalitys municipality s domicile friends neighbors effect lists.Keywords listsKeywords lists Keywords localism concentration behaviour geography 20 2

Resumen Mientras que los primeros estudios sobre estrategias electorales sostenían que el sistema adoptado en Brasil fomenta el “voto personal” y la creación de bastiones electorales geográficamente localizados, estudios más recientes demuestran que la estrategia electoral más eficaz es la dispersión de los votos. Según la perspectiva contextual, las personas votan a candidatos a cuyos mensajes políticos tienen acceso y que corresponden a las exigencias de los lugares donde viven. A partir de la construcción de una base de datos sobre las elecciones legislativas de 2010 a 2018, tratamos de interpretar los resultados encontrados desde esta perspectiva. Partiendo de la hipótesis de que el voto se rige por la forma en que se difunde la información en el espacio, comprobamos que la mayoría de los candidatos obtienen el mayor número de votos en su domicilio electoral declarado, que los que sólo tienen experiencia municipal muestran un patrón de voto coherente con el efecto “amigos y vecinos” y que existe una coordinación partidista en la formación de las listas. personal localizados contextual viven 201 2018 espacio declarado amigos vecinos listas 20 2

Résumé Alors que les premières études sur les stratégies électorales soutiennent que le système adopté au Brésil encourage le “vote personnel” et la création de bastions électoraux géographiquement localisés, des études plus récentes montrent que la stratégie électorale la plus efficace est la dispersion des votes.

Abstract This article proposes an indicator that describes each Brazilian municipality’s learning level of its elementary school students, as well as learning inequalities among groups of students defined by socioeconomic status, race, and sex. This indicator is necessary because learning inequalities are growing and are not observed by the country’s main educational indicator, the Basic Education Development Index (IDEB). This study initially conceptualizes justice in education, positioning itself in the debate on theories of justice. Then, it presents the methodological aspects of the indicator and the results obtained. The main finding is that the subjects and school grades in which the highest number of municipalities increased their learning levels are also those in which there was a strong increase in inequalities. municipalitys municipality s status race sex countrys country IDEB.

Abstract This study investigated the effect of dolomitic lime incorporation on the microstructure and mechanical properties of metakaolin-based geopolymers activated by alkaline solution. Five geopolymer mixtures were prepared with the addition of 0.0%, 2.5%, 5.0%, 7.5%, and 10.0% dolomitic lime. The microstructure of the geopolymers was evaluated by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and X-ray diffraction analyses (XRD). The compressive strength of the mixtures ranged between 53.2 and 63.0 MPa after 28 days of ambient curing. SEM/EDS analyses showed that the main phases formed were the N-A-S-H gel together with the C-A-S-H and N-M-A-S-H gels in the mixtures with dolomitic lime. In summary, the results showed that the incorporation of dolomitic lime can significantly improve the microstructure and properties of geopolymers. metakaolinbased metakaolin based solution 00 0 0.0% 25 2 5 2.5% 50 5.0% 75 7 7.5% 100 10 10.0 SEM, SEM , (SEM) energydispersive energy dispersive Xray X ray EDS, EDS (EDS) XRD.

High-density polyethylene (HDPE) geomembranes are commonly used as an environmental protection liner due to their good chemical and mechanical resistances and low cost. Ultraviolet (UV) radiation is an essential issue in durability studies for pond applications. This study evaluated a 1.5-mm thick HDPE geomembrane exposed to ultraviolet fluorescent radiation for 8760 h in a laboratory and thermoanalytical and physical analyses were conducted towards the understanding of its performance after exposure. According to the results, although the geomembrane maintained the ductile behavior, it showed a 52.48% final decrease in stress crack resistance (SCR) compared to virgin SCR. Moreover, a considerable antioxidant depletion occurred after 8760 h exposure shown by the Std. OIT (standard oxidative-induction time) results, demonstrating a Std. OIT value decrease of 89.19% compared to the virgin Std. OIT. Such a behavior contributed to the susceptibility of thermal effects in the DSC (differential scanning calorimetry) curves and the losses observed in the SCR values, attesting the geomembrane’s oxidative degradation mechanism occurred and changed the polymer’s structure.

ABSTRACT Purpose: This study aimed to analyze variations in intraoperative corneal thickness during corneal cross-linking in patients with keratoconus and to investigate its possible correlation with presurgical maximal keratometry (Kmax) and pachymetry. Methods: This was a prospective case series. We used a method similar to the Dresden protocol, with the application of hydroxypropyl methylcellulose 0.1% hypo-osmolar riboflavin in corneas between 330 and 400 µm after epithelium removal. Corneal thickness was measured using portable calipers before and immediately after epithelium removal, and 30 and 60 min after the procedure. Results: The 30 patients in this study were followed up for one year. A statistically significant difference was observed in pachymetry values during the intraoperative period (p<0.0001) and an increase of 3.05 µm (95%C1: 0.56-5.54) for each diopter was seen after epithelium removal (p0.019). We found an average Kmax difference of —2.12 D between men and women (p0.013). One year after treatment, there was a statistically significant reduction in pachymetry (p<0.0001) and Kmax (p0.0170) values. Conclusions: A significant increase in pachymetry measurements was seen during the procedure, and most patients showed a regression in Kmax and pachymetry values one year after surgery.

Alzheimer’s disease (AD) is a most common form of dementia and results in memory loss, disorientation, impaired thinking and changes in personality as well as mood. The dementia cases mostly turn into the Alzheimer’s disease (AD). Another disease, the Parkinson’s disease (PD), mainly affects dopaminergic neurons in substantia nigra. A series of previously synthesized quinolone-triazole hybrids were investigated and evaluated for their anti-acetyl cholinesterase and against monoamine oxidase reactive properties through in silico characterization. The ground state electronic properties were determined by electron density of the compounds through DFTs (density functional theory) calculation. The geometries of all compounds were optimized using Becke-3-parameter-Lee-Yang-Parr (B3LYP) method and 6-311g basis set. Docking studies were conducted using the AutoDock and Molecular Operating Environment (MOE) software and the results of the potent derivatives found to be encouraging. The data confirmed that all the compounds have drug-like properties and was further confirmed by ADMET (absorption, distribution, metabolism, excretion and toxicity) properties.

Nanoparticles of TiO2 doped with low amount of Fe were synthesized from natural ilmenite obtained from alluvial gold mine wastes. The obtained TiO2 were characterized using X-ray diffraction (XRD), X-ray fluorescence (XRF), Fourier-transform infrared spectroscopy (FTIR), UV-Vis diffuse reflectance, thermogravimetric analysis/differential scanning calorimetry (TGA/DSC), N2 adsorption-desorption isotherms, transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The results confirm the formation of mesoporous TiO2 nanoparticles in anatase phase with 0.05 wt.% of iron possibly replacing some titanium places. All the characterizations were performed to the synthesized solid and the reference materials (TiO2 anatase and Degussa P25). The photocatalytic activity of both the synthesized solid and references were evaluated in the photo-oxidation of cyanide in aqueous medium under UV illumination. An experimental design type Box-Behnken was performed choosing three different parameters: the initial concentration of cyanide (50, 150 and 250 ppm) the catalyst load (0.1, 0.5 and 1.0 g L-1) and the oxygen source. The percentage of cyanide conversion was chosen as response in the design obtaining as optimal conditions [CN-]0 = 50 ppm, catalyst load = 0.6 g L-1 and air bubbling. Under these conditions it was reached 32, 32 and 89% of cyanide conversion for Fe-TiO2 synthesized, TiO2 anatase and Degussa P25, respectively.

Protium ovatum Eng. Burseraceae is an endemic species in Brazil used in traditional medicine. This study investigated the chemical variation and the in vitro antioxidant and antimicrobial properties of dichloromethane soluble fraction of hydrolate (DSFH) from leaves of P. ovatum collected from five different vegetation physiognomies within the Cerrado Goiano. The region was characterized based on the DSFH chemical composition by gas chromatography coupled to mass spectrometry (GC-MS) analysis. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) were performed to compare the different DSFHs from five Savannah regions in Brazil. The DSFHs from the Cerrado stricto sensu (CSS), Mata de Galeria (MG) and Cerradão (C) regions were grouped in the negative part of PC1, showing high similarity. Samples from the C and MG regions showed antioxidant activity of IC50 = 0.98 and 0.78 mg mL-1, respectively, and 0.250 mg mL-1 of butylated hydroxytoluene (positive control). DSFH from different regions exhibited antifungal activity against Candida albicans. The results show that the chemical composition and the biological activity of DSFHs can be affected according to the area of collection.

The present work reports the in situ fabrication of Ag nanoparticles (AgNPs) in polystyrene-b-poly(2-vinylpyridine) (PS-b-P2VP) over pre-patterned hydrophobic stripes on a hydrophilic glass surface. Microcontact printing (μCP) using octadecyltrichlorosilane (OTS) as “ink” was used to obtain these chemically modified substrates. A comparison of the results of the PS-b-P2VP self-assembly over a bare glass substrate and a pre-patterned glass substrate demonstrated the influence of the pattern on the film morphology. Polymeric films of Ag+ and PS-b-P2VP were prepared on a pre-patterned substrate and heated at 150 °C to enable the self-reconstruction of the polymeric matrix and the in situ formation of AgNPs (average particle size of approximately 100 nm). The AgNP/PS-b-P2VP thin films were characterized using UV-Vis spectroscopy and atomic force microscopy. The results demonstrate that the concentration of the solutions of Ag+/PS-b-P2VP used to prepare the films strongly influences the morphologies and dispersion of AgNPs. Moreover, the surface-enhanced Raman spectroscopy (SERS) activity of the fabricated polymer nanocomposites using Nile Blue as a molecular probe shows the importance of the chemical modification of the substrate in the enhancement of the SERS signal.

The selective separation of precious metals from complex aqueous solutions is important in protecting the environment, aquatic ecosystems, water resources and recycling resources. In this study, cysteine-containing polymeric nanoparticles were synthesized using the molecular imprinting (MIP) technique with the mini-emulsion polymerization method. The basis of the polymer design is inspired by affinity of silver to cysteine in biological systems. The synthesized silver ion imprinted (Ag+-IIP) poly(hydroxyethylmethacrylate-N -methacryloyl-L-cysteine) poly(HEMA-MAC) nanoparticles were characterized by elemental analysis, zeta sizer, Fourier transform infrared (FTIR) spectroscopy, atomic force microscopy (AFM), and scanning electron microscopy (SEM). The effects of pH, ionic strength and interaction time on adsorption of Ag+ ions were investigated. In experimental studies, the highest adsorption amount (196.9 mg g1 nanoparticle) was reached in a short period of 40 min at pH 5.0 and 150 mg L-1 concentration. Selectivity studies of synthesized Ag+-IIP nanoparticles against silver (Ag+) ions were carried out in the presence of lithium (Li+), barium (Ba2+), mercury (Hg2+) and cadmium (Cd2+) ions. Experimental results indicate that nanoparticles adsorb Ag+ ions with high selectivity. Ag+-IIP nanoparticles have 3.7, 3.1, 2.4, and 2.6 times more selective or higher affinity for Ag+ ions compared to Li+, Ba2+, Hg2+ and Cd2+ ions, respectively, compared to Ag+-non-imprinted (NIP) nanoparticles. environment ecosystems study cysteinecontaining containing MIP (MIP miniemulsion mini emulsion method systems Ag+IIP AgIIP IIP Ag (Ag+-IIP polyhydroxyethylmethacrylateN poly hydroxyethylmethacrylate N methacryloylLcysteine methacryloyl L -methacryloyl-L-cysteine polyHEMAMAC HEMA MAC poly(HEMA-MAC analysis sizer FTIR (FTIR spectroscopy AFM, AFM , (AFM) SEM.

The training of Chemistry teachers in Brazil has been researched for a few decades and studies point out to training gaps that reverberate in teaching, especially in basic education. One of the contents covered in this step and which is part of the high school curriculum is radioactivity, which is related, among other things, to radiological and radioactive accidents that occur around the world. Thus, this research sought to investigate how the training provided to Chemistry undergraduates in the state of Goiás is in relation to the subject of radioactivity, since in 1987 a radiological accident occurred in Goiânia with a Cesium 137 source. This is a qualitative research, data were collected via questionnaire and the analytical technique used was discursive textual analysis (ATD). The results showed that due importance was not given to the radiological accident, since there is evidence of training gaps in relation to the topic of radioactivity in Chemistry degree courses in the state of Goiás, where the accident occurred, and the contents on radioactivity are either not addressed, or the approach is superficial. This fact directly impacts the teacher’s performance in basic education, when working on this content with their students. teaching education related things world Thus 198 13 source ATD. ATD .

Lantana caatingensis Moldenke (Verbenaceae) is an endemic plant from northeastern Brazil. However, its chemical composition is almost unknown. This study aimed to characterize the chemical compounds found in L. caatingensis and investigate the antileishmanial potential of its hydroalcoholic extract and polar fractions. Compounds present in the hydroalcoholic extract obtained from L. caatingensis leaves and its polar fractions (ethyl acetate and methanolic) were analyzed by liquid chromatography with a photodiode-array detector coupled to electrospray ionization quadrupole time-of-flight mass spectrometry. An antileishmanial assay was performed in a 96-well plate against Leishmania major promastigotes using resazurin on a plate spectrophotometer and the results were expressed as percentage of growth inhibition. Nine compounds were determined in the investigated extract and fractions, classified as flavonoids, flavonoid C-glycosides and phenylethanoid glycosides. The antileishmanial activity revealed that the hydroalcoholic extract and the ethyl acetate fraction were active against L. major promastigotes with inhibitory concentration of 71.78 and 26.86 µg mL-1, respectively, while the methanolic fraction was inactive (478.40 µg mL-1). This is the first report on the chemical composition and antileishmanial activity of L. caatingensis extracts. These results contribute to further knowledge of species belonging to the Lantana genus.
