Abstract This article aims to investigate a unique path in the reception and translation of Antonio Gramsci’s ideas in Brazil. This work attempts to reconstruct Fernando Henrique Cardoso’s political thought during the Brazilian military dictatorship and democratic transition (1964-1988), focusing on his interpretation and use of Antonio Gramsci’s ideas to analyze state formation, social classes and politics in Brazil. The paper argues that the Gramscian concepts are central to Cardoso’s political thought in three phases of Gramscian refraction: (i) between 1964 and 1974, in the thesis of the Brazilian bourgeoisie’s dependent hegemony; (ii) between 1974 and 1983, in the argument of the Brazilian state as the “Modern Prince” as a concept for the analysis of the agrarian-industrial-military coalition in the post-1964 period; and (iii) from 1983 to 1988, in the definition of the Brazilian economic and military elites’ behavior as a authoritarian-scletortic transformism in the face of the pressures for the democratization of the political regime. Cardoso’s uses of Gramscian concepts are creative at all these moments. That is, the Brazilian thinker draws on Gramscian concepts to create his own lexicon to employ in the analysis of Brazilian politics. The article therefore explores not only the reception, but also the translation of Gramsci’s ideas in Fernando Henrique Cardoso.

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

Abstract The internal colonization policy in post-Independence Brazil was continuously activated and transformed throughout the 19th and 20th centuries in order to control unsubmissive populations and territories. From the bibliographic and documentary analysis of a set of colonization projects and experiences, it was possible to reconstruct the interpretative framework of this policy, emphasizing the period of the corporate-military dictatorship and its meaning of transformation of the traditional peasantry into the rural middle class. We sought to identify the main elements that constitute this stratum, its characteristics and expectations based on the set of values, interests and assumptions of the techno-corporate-military complex, highlighting the role of the colonization policy in its formation. The continuities and reconfigurations of this policy allow us to state that talking about colonizing while it is the hidden verb of the treatment given to the national agrarian question. postIndependence post Independence th territories experiences corporatemilitary corporate military class stratum values technocorporatemilitary techno complex formation question

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 Schröeder-van Laar equation to predict the theoretical eutectic melting temperature values was applied to a set of fourteen binary mixtures (UR1 to UR14). The fourteen binary mixtures belong to a structurally diverse group of organic molecules. They are represented by the 5-membered heterocycles containing N-S and N-O rings, flexible methylene chains (RH), semi-rigid semi-fluorinated chains (RF), and hydrogen bonds (HB). A virtual screening totalizing ninety-one possible theoretical combinations was planned. The UR1 to UR14 were prepared by mixing individual components using the calculated mole fractions. The experimental (Te) and theoretical (Tt) temperatures for the eutectic melting points were determined using polarized optical microscopy (POM) and differential scanning calorimetry (DSC) techniques. Heterogeneous mixtures were formed for components with large structural diversity as seen by POM. During the melting of the mixtures, irregular behavior through the segregation of the components was recorded. The study showed that the similarities in structural diversities favor the formation of homogeneous mixtures, with Te values approaching Tt, as predicted by the Schröeder-van Laar equation and by the theory of eutectic mixtures. Liquid crystal properties were affected in homogeneous binary mixtures containing one of the individual liquid crystal components. Schröedervan Schröeder van UR (UR UR14. .

Parthenolide (PTN) is a secondary metabolite of the plant Tanacetum parthenium (L.) Schulz Bip. and is considered the chemical marker of this species. This sesquiterpene lactone (germacrene skeleton) has been described as responsible for the biological activity of the leaf extract. In addition, several studies in the literature have demonstrated its antiparasitic and antineoplastic activity. However, there is a need for knowledge of other safety parameters, such as pharmacokinetic, pharmacodynamic and toxicity evaluations. Therefore, in this investigation, the in vitro metabolism of parthenolide was performed with rat liver microsomes and biomimetic metabolism (such as cytochrome P-450 system) using organometallic catalysts. The biomimetic procedure was validated since the major compound of biomimetic oxidative reaction with meta-chloroperbenzoic acid catalyzed by metalloporphyrin 5,10,15,20-tetrakis(pentafluorophenyl)-porphyrin iron(III) chloride was also observed with rat liver microsomes. Previous chemoenzymatic synthesis studies of PTN afforded the same epoxide formation, this major oxidative compound was isolated and fully characterized as (1 R,10R)-epoxyparthenolide based on experimental and theoretical calculations of infrared (IR) and vibrational circular dichroism (VCD) data at the B3PW91/6-311G. Furthermore, for the first time, this metabolite was evaluated for trypanocidal and leishmanicidal activity. The mean inhibitory concentration (IC50) values were lower for PTN than its metabolite and showed significant cytotoxic effects for both parasites. This finding holds promise for addressing neglected diseases. (PTN L. L (L.

The exploration of carbon steel corrosion inhibition in 0.5 mol L-1 H2SO4 using extracts from Hymenaea courbaril (HC) has resulted in significant findings. Extracts from the bark, leaves, fruit pulp, and fruit shell have all proven to be effective corrosion inhibitors, as demonstrated through surface studies and electrochemical methods. Infrared spectroscopy and high-performance liquid chromatography have identified the presence of phenolic compounds, which are known to have corrosion-inhibiting potential. UV-Vis spectroscopy has further revealed the adsorption of extract species on the steel surface. Electrochemical studies have confirmed the inhibition of corrosion, allowing to propose mechanisms of both chemisorption and physisorption. X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS) have provided evidence of the formation of an inhibitory layer, further supporting the inhibition of corrosion. Langmuir isotherms have indicated favorable adsorption of the extracts, while reduced surface roughness suggests improved protection of the steel surface. Activation energy calculations have demonstrated an increase in energy barriers, resulting in slower corrosion rates. These findings suggest that extracts from Hymenaea courbaril show promise as eco-friendly corrosion inhibitors, with potential industrial applications. Further research is needed to optimize the extraction process and fully understand the inhibition mechanisms. 05 0 5 0.

BiOCl/KBiO3 p-n heterostructures with hierarchical mesoporous architectures were successfully synthesized via a facile in situ method. The X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscope (SEM) results indicate the formation of heterojunctions between BiOCl and KBiO3. The photocatalytic performance of the as-prepared samples was investigated by the degradation of dye Rhodamine B (RhB) under visible light irradiation. BiOCl/KBiO3 composite has never been used to photodegrade the RhB which is a common dye and very difficult to degrade. The results demonstrated that KBiO3 combined with proper amount of BiOCl nanosheets exhibited high efficiency in the photocatalytic process, and BiOCl/KBiO3 with the molar ratio of 70/30 demonstrated the highest photocatalytic activity due to its large surface area, excellent charge separation characteristics and the suppressed recombination of electron-hole pairs. The results of active species detection reveal that the superoxide radical anions (O2-), hydroxyl free radicals (·OH), photogenerated holes (h+) and photogenerated electrons (e-) reactive species work together for the photocatalytic degradation of RhB. A possible and new mechanism of photocatalysis that differs from other teams was also explored and proposed. The present study will benefit the development of the new p-n heterojunction photocatalysts and would be of great importance to meet ever-increasing environmental demands in the future.

In order to extract hesperidin from Citrus aurantium L. through green and efficient ways, a novel method based on deep eutectic solvent (DES) assisted extraction has been developed. Compared to known alkali extraction and acid precipitation or organic solvent (ethanol, methanol) extraction, this new DES system of choline chloride/diethanolamine (DES-14) method exhibited excellent extraction efficiency for hesperidin. Under optimal conditions, the extraction yield of hesperidin reached 6.26 ± 0.05%. Further studies with infrared spectroscopy, 1H nuclear magnetic resonance, and density functional theory showed the DES-14 was formed mainly through the interaction of H-bond and van der Waals forces. In addition, scanning electron microscopy and density functional theory revealed the strong dissolving capacity, and the H-bond formation between DES-14 and hesperidin, as well as van der Waals forces all contributed to efficient extraction of hesperidin. The results provide a new strategy for efficient extraction and utilization of hesperidin in Citrus.

Resumo O Distrito Industrial de Marabá (DIM) é um local vinculado à transformação e ao beneficiamento de recursos sob uma ótica de agregação de valor ao minério de ferro de Carajás-PA. Porém, indústrias locais promoveram grande transformação espacial com o emprego de técnicas e tecnologias arcaicas e poluentes que, após aumento nos custos e alteração nos preços internacionais, tiveram as áreas abandonadas, indicando um processo de campo marrom (brownfield) em formação no DIM e áreas conexas. Seguiu-se um processo de transumância, acompanhado de ciclos de retração e concentração econômica.

Abstract The Marabá Industrial District (MID) is a place connected with the transformation and processing of resources from the perspective of adding value to the iron ore of Carajás (State of Pará). However, local industries have promoted a great spatial transformation, using archaic and polluting techniques and technologies. After an increase in costs and changes in international prices, the areas of these industries were abandoned, indicating a brownfield process under formation in the MID and related areas. This was followed by a process of transhumance, accompanied by cycles of economic contraction and concentration. A mining-industrial periphery condition is perceived in the implementation and conception of the MID, as well as its formation as a brownfield, with spatial, economic, demographic, and environmental repercussions.

The composites of poly (butylene adipate co-terephthalate) / poly (lactic acid) (PBAT/PLA) blend and montmorillonites functionalized using imidazole-derived ionic liquids with different carbon chain sizes (butyl, octyl, and dodecyl) proved to be a promising alternative for improving the thermal and mechanical properties of the polymer blend. Functionalization of montmorillonites by ionic liquids was confirmed by increasing the basal spacing, and spectroscopical and thermal analysis evidence. The composite synthesis was carried out by casting technique generating homogeneous polymeric films. X-ray diffraction analyses suggested that montmorillonite functionalization with the ionic liquid of the butyl carbon chain fostered exfoliation and incorporation of the clay into the polymer. Furthermore, an increase in the thermal stability and mechanical properties of the material was observed. The other composites formed between the PBAT/PLA blend and the montmorillonite functionalized by ionic liquids of higher carbonic chain showed micro composites formation. Thus, their thermal and mechanical properties had no significant improvements. butylene coterephthalate co terephthalate co-terephthalate lactic acid PBATPLA PBAT PLA (PBAT/PLA imidazolederived imidazole derived butyl, (butyl octyl dodecyl spacing evidence films Xray X ray Furthermore observed formation Thus improvements

To control vehicle emissions, the new homologation process must be reported according to the California Maximum Incremental Reactivity (MIR) scale’s procedure to calculate the ozone forming potential (OFP) of each new vehicle. This work calculates an MIR scale suitable for the Brazilian reality. Meteorological and hourly pollutant data from the Bangu Automatic Air Quality Station was inventoried and processed from March to September 2020 to adjust OZIPR Lagrangean model and obtain the MIR scale by making small increments in the concentrations of each volatile organic compounds (VOC) and calculate the ozone increase/decrease. It was found that the VOC that had the greatest impact on ozone formation was 1,2,4-trimethylbenzene, with 2.06 ppb O3 ppbC-1 VOC. The OFP was calculated based on the VOC emissions of a vehicle and it was found a value of 9.421 mg O3 km-1, a much lower value when compared using the California MIR scale of 136.608 mg O3 km-1. It is concluded that meteorological conditions and VOC speciation data in the air mixture in the studied region directly affect the photochemical reactions of ozone formation.

The ability to argue is essential for the education of students, as it is fundamental to the presentation of ideas on a given topic. Several methods have been proposed in studies that support the development of argumentation in different teaching contexts, such as the heuristic diagram. It allows the organization and recording of activities that enable critical reflection through the analysis of the language used to express ideas. In this perspective, the diagrams produced for solving problems in an experimental chemistry subject offered in an undergraduate chemistry course were analyzed. Toulmin’s argument pattern was used as a basis to identify the structure of the arguments produced, and then, the quality of the arguments was evaluated. The results of the analysis showed a principle of progress in the argumentative capacity of undergraduates with the development of activities, verified by the presence of elements in students’ texts that, when present, validate an argument. Thus, the results can contribute to other researches in the field of chemical education by favoring a teaching process that considers the development of initial argumentative ability in the formation of students. students topic contexts diagram perspective analyzed Toulmins Toulmin s then evaluated present Thus
