title: Nothing is forever: an essay on the urban arts of Miguel Januário±MaisMenos±

description: Abstract In this article we intend to analyze Miguel Januário’s politically engaged artistic interventions, in the last decade, characterized by the seriousness of a severe economic, financial and social crisis in Portugal. The work presented here underlies a purpose based on a primordial heuristic principle: to demonstrate that street art is a matter and object of social intervention, demarcating a specific space in the denunciation and revelation of social issues; also, multiplying and questioning, thus, the forms and contents of the urban arts.

title: Os padrões urbano-demográficos da capital paulista

description: abstract This work identifies and analyzes characteristics of the census sections of São Paulo’s capital, grouping them in eight different patterns. In order to separate these areas into clusters (segments) representing intragroup homogeneity, variables were selected that take into account the conditions and changes of the population, environment, crime rates, housing, mobility and urban expansion. Each of these clusters (segments) portrays a different demographic profile and urban pattern. Thus, it is proposed that clustering these similar groups (i.e., reducing intragroup variance/variation and maximizing the intergroup variance/variation) enables a better understanding of the city’s singularities and of what these singularities entail. Furthermore, an inter- and transdisciplinary perspective highlights the need to adjust the sampling, data collection and valuation strategies, as well as the identification, description, and study of São Paulo’s capital.

title: Development and Psychometric Properties of the Attitude Toward Science Scale

description: Abstract This study presents the development and evidence of validity of the Attitude Toward Science Scale (ATSS). Participants included 697 individuals (53.5% men), aged between 18 and 75 years (M = 27.51, SD = 9.8) in several Brazilian states. Exploratory factorial analysis (EFA) and confirmatory factor analysis (CFA) showed that ATSS has a two-factor structure (Personal Initiative and Beliefs & Affects). ATSS comparisons with sociodemographic variables revealed that men have a more favorable attitude towards science (ATS) than women, non-religious individuals show more favorable ATS than religious ones, students of public universities have more favorable ATS than those of private universities, students of hard sciences show more favorable ATS than those of humanities and a positive correlation between ‘need for knowledge’ and ATS. ATSS shows reliable and valid adequacy for measuring attitude towards science in Brazilian samples.

title: Effect of Hydrofluoric Acid Concentration and Thermal Cycling on the Bond Strength of Brackets to Ceramic

description: Abstract This study to evaluate the effects of different hydrofluoric acid (HF) concentrations and thermal cycling on the shear bond strength (SBS) of brackets to ceramic. Cylinders of ceramic were divided into 10 groups (n=15), according to HF concentrations: 1-1%;2-2.5%;3-5%;4-7.5%;5-10% (storage 24 h); 6-1%;7-2.5%;8-5%;9-7.5%; and, 10-10% (thermal cycling). All cylinders were etched for 60s and received one layer of silane. Metallic brackets were bonded to the cylinders using Transbond-XT, light activated for 40 s, using a LED (Radii Plus) and stored in deionized water at 37o C for 24h. The groups 6 to 10 were submitted to thermal cycling (7,000 cycles - 5o/55oC). SBS was performed in an Instron at crosshead speed of 1.0 mm/min. Data were submitted to two-way ANOVA and Tukey’s post-hoc test (α=0.05). The Adhesive Remaining Index (ARI) was evaluated at 40x magnification. The different HF acid concentrations influenced on the SBS of the brackets to ceramic (p&lt;0.05). The thermal cycling decreased the SBS of the brackets to ceramic for all acid concentrations (p&lt;0.05). The ARI showed a predominance of scores 0 for all groups, with an increase in scores 1, 2 and 3 for the group storage for 24 h. In conclusion, the different HF acid concentrations 5.0%, 7.5% and 10% influenced on the SBS of brackets to ceramic. The thermal cycling decreased significantly the SBS of brackets to ceramic.

title: Size and shape-controlled nanomaterials based on modified polyol and thermal decomposition approaches. A brief review.

description: Abstract: Since its inception in 2007, the Colloidal Materials Group, one of the research groups in nanotechnology of the Institute of Chemistry of São Carlos (IQSC) at University of São Paulo (USP) carries out studies related to the development of syntheses methods of nanoparticles and multifunctional nanostructured systems. Our works search new synthesis methodologies that allow high size and shape control of the individual nanoparticles or that compose the nanostructured systems and has as a principle the synthetic approaches based on the modified polyol and thermal decomposition processes. Systems involving nanoparticles have received extensive attention both in the fundamental research and in several technological applications exploring the unique properties presented in nanomaterials. These properties are strongly size- and shape-dependent of the nanoparticles and a large distribution of size or shape implies in a high response dispersion, justifying the intense research for the so-called nanoparticle monodisperse systems. In this review, we present the main aspects to obtain monodisperse nanoparticulate systems, correlating with the synthesis processes used in our group and some of our results in systems involving nanoparticles with magnetic, optical, and electronic properties, as well as some obtained composite materials for different applications.

title: Post-orogenic tectonic evolution of the suture zone between the North China Craton and South China Block: Insights from a petrostructural study of the Late Mesozoic granites, Jiaodong Peninsula, East China

description: Here we present the data of anisotropy of magnetic susceptibility for Late Mesozoic plutons submitted to Journal of Geophysical Research- Solid Earth.Abstract of the study: The Late Mesozoic tectonics of East China is characterized by widespread magmatism, large-scale thrusting and folding, extensional dome structures, strike-slip faulting and block rotation. As a part of East China, the Sulu orogen is famous for its ultra-high pressure (UHP) metamorphism related to the Triassic continental deep subduction of South China Block (SCB) beneath the North China Craton (NCC), and the post-orogenic tectonics have reactivated major lithospheric structures of the Triassic orogen. Hence, the Late Mesozoic post-orogenic tectonic evolution is essential to understand the architecture of the UHP orogen and tectonic framework of East China. Polyphase deformations and magma emplacement have been recognized within the suture zone between NCC and SCB. Magnetic fabrics and Gravity modeling reveal the Late Jurassic plutons have concentric magnetic foliation pattern, NE–SW trending magnetic lineation, and NW–SE trending feeder zones at the depth. A significant D<sub>1</sub> event with a top-to-the-NE high-temperature shearing, coeval with the emplacement of the Late Jurassic plutons, is recognized. These results support a genetic link between the Late Jurassic pluton emplacement and regional NE–SW extensional tectonics. A compressional deformation (D<sub>2</sub>) is related to the Late Jurassic to Early Cretaceous southeastward thrusting. A subsequent extensional D<sub>3</sub> event with age around 126 Ma is featured by rolling-hinge structure with a top-to-the-WNW ductile shearing, corresponding to the Early Cretaceous NW–SE extensional tectonics. These new data indicate that the post-UHP orogen experienced a complex Late Mesozoic tectonics evolution, and are considered in a geodynamic model of the North China Craton destruction.<br>

title: Hydrogen production from aqueous glycerol using titanate nanotubes decorated with Au nanoparticles as photocatalysts

description: Abstract: Protonated titanate nanotubes (HTiNts) were synthesized using the hydrothermal method, followed by proton exchange with acid. Gold nanoparticles decorated titanate nanotubes (AuHTiNts) were obtained by the reduction of AuCl4- under vigorous stirring with an aqueous solution of HTiNts containing 1 wt% of ascorbic acid. To investigate the surface structural chemistry of the titanate and AuHTiNts, the following characterization methods were used: scanning and transmission electron microscopy, X-ray diffraction, UV-Vis diffuse reflectance spectroscopy, Raman spectroscopy and X-ray photo-electron spectroscopy. The mean internal and external diameters for titanate nanotubes were found to be 5.46 ± 0.08 nm and 8.42 ± 0.03 nm, respectively, whereas the mean diameter of gold nanoparticles was measured to be 9.68 nm ± 0.03 nm. The as-synthesized AuHTiNts was used as photocatalyst in hydrogen production from glycerol as a sacrificial agent. The enhancement in the production of hydrogen, using the heterogeneous AuHTiNts catalysts, can be attributed to the intrinsic catalytic potential of gold as well as its interactions with titanate nanostructure.

title: Impact of calcium aluminate cement with additives on dental pulp-derived cells

description: Abstract Calcium aluminate cement (CAC) has been highlighted as a promising alternative for endodontic use aiming at periapical tissue repair. However, its effects on dental pulp cells have been poorly explored. Objective: This study assessed the impact of calcium chloride (CaCl2) and bismuth oxide (Bi2O3) or zinc oxide (ZnO) additives on odontoblast cell response to CAC. Methodology: MDPC-23 cells were exposed for up to 14 d: 1) CAC with 2.8% CaCl2 and 25% ZnO (CACz); 2) CAC with 2.8% CaCl2 and 25% Bi2O3 (CACb); 3) CAC with 10% CaCl2 and 25% Bi2O3 (CACb+); or 4) mineral trioxide aggregate (MTA), placed on inserts. Non-exposed cultures served as control. Cell morphology, cell viability, gene expression of alkaline phosphatase (ALP), bone sialoprotein (BSP), and dentin matrix protein 1 (DMP-1), ALP activity, and extracellular matrix mineralization were evaluated. Data were compared using ANOVA (α=5%). Results: Lower cell density was detected only for MTA and CACb+ compared with Control, with areas showing reduced cell spreading. Cell viability was similar among groups at days one and three (p&gt;0.05). CACb+ and MTA showed the lowest cell viability values at day seven (p&gt;0.05). CACb and CACb+ promoted higher ALP and BSP expression compared with CACz (p&lt;0.05); despite that, all cements supported ALP activity. Matrix mineralization were enhanced in CACb+ and MTA. Conclusion: In conclusion, CAC with Bi2O3, but not with ZnO, supported the expression of odontoblastic phenotype, but only the composition with 10% CaCl2 promoted mineralized matrix formation, rendering it suitable for dentin-pulp complex repair.

title: Occurrence of arbuscular mycorrhizal fungi on King George Island, South Shetland Islands, Antarctica

description: ABSTRACT Arbuscular mycorrhizal fungi make up an important ecological niche in ecosystems, and knowledge of their diversity in extreme environments is still incipient. The objective of this work was to evaluate the density and diversity of arbuscular mycorrhizal fungi in the soil of King George Island in the South Shetland Islands archipelago, Antarctica. For that, soil and roots of Deschampsia antarctica were collected at the brazilian research station in Antarctica. The spore density, species diversity and mycorrhizal colonization in the roots were evaluated. There was a low density of spores (27.4 ± 17.7) and root mycorrhizal colonization (6 ± 5.1%), which did not present statistical difference. Four species of arbuscular mycorrhizal fungi were identified, distributed in two genera: three species of the genus Glomus (Glomus sp1, Glomus sp2 and Glomus sp3) and one of the genus Acaulospora, which was identified at species level (Acaulospora mellea). Greater soil diversity was verified with pH 5.9 and phosphorus concentration of 111 mg dm-3, occurring two species of genus Glomus and A. mellea. Based on literature data, this may be the first record of this species of Acaulospora mellea in Antarctic soils, colonizing D. antarctica plants.

title: Approaching Challenges in Teaching Learning Process of Statistics in Psychology Graduation Courses: a didatic contract overlook

description: Abstract Teaching concepts, competences and skills related to data analysis in Psychology graduation courses has proved to be a challenging issue. In the sphere of Mathematic skills, Statistics is indeed out of the scope of what is usually faced in the reminder of courses. The present work investigates features of the structure of the classroom in a course on Statistics from the Psychology graduation curriculum. For such purpose, we set the didactic contract as a theoretical guide, a “lunette” that allowed for observing the functional dynamics of the classroom, searching aspects that might be related to difficulties in the teaching-learning process. To enhance the analysis of the dynamics of the courses' performance, we carried out a comparative overview with a discipline having the usual structure characteristic from the Psychology graduation curriculum. This study is based not only on video-graphic registers of the classes, but in interviews with its professors as well. The compiled data was submitted to a clinical-interpretative analysis, pointing to several differentiation factors between the two disciplines, among them: classroom dynamics and evaluation systems. Specific to the Statistics course, important aspects appeared as negative interferences to the learning process, such as excessive manipulation of mathematical/statistical algorithms without the aid of informatics and computed data-processing. This study points to the importance of clarity in establishing a syllabus with respect to content, objectives, and structure of the statistics discipline in Psychology courses, in order to outline ways of didactic/pedagogical improvement for its offer…
