1. Synthesis and Molecular Modeling Study of Two Bromo-Dimethoxybenzaldehydes
This work describes the synthesis, molecular structure, and packaging of the compounds 6-bromo-2,3-dimethoxybenzaldehyde (6-BRB) and 5-bromo-2,3-dimethoxybenzaldehyde (5 BRB). Characterization in the solid-state was carried out by X-ray diffraction, and the analysis of the interactions was described by the Hirshfeld surface, which helps in understanding the

2. A 2.4 GHz Coplanar Solar Cell Patch Antenna with a Semi-Analytical Evaluation of Temperature Effects
Abstract Solar cells integrated with antennas have aroused scientific interest as an attractive energy source alternative in low power devices for IoT and Wireless Sensor Network applications. Since the space for all components in the systems is scarce, different integration ideas have been proposed in this field. However, further analysis of the performance

3. A New Miniaturized Low-Profile and Stable Dual-Band FSS with 2.5D Structure for ISM Bands
Abstract Based on 2.5-Dimensional (2.5D) frequency selective surface (FSS) structures, a new miniaturized frequency selective surface structure is proposed in this work to operate as a bandreject filter in the 2.4 GHz (2400 to 2483.5 MHz) and 5 GHz (5150 to 5350 MHz and 5470 to 5725 MHz) ISM (Industrial, Scientific, and Medical) bands. The FSS has the metall

4. Organophilic clays and their application in atrazine adsorption
Abstract Atrazine’s adsorptive capabilities make the use of clays practical and effective. Three types of organophilic clays modified by cationic surfactants with the ability of one of these clays to adsorb atrazine in an aqueous medium are discussed in this work. The modification in clays was done with the surfactants cetyltrimethylammonium bromide, cetyl

5. INTERMEDIALITY, INTERTEXTUALITY AND PARODY: RESONANCES OF JANE AUSTEN IN JOHN FOWLES’S THE FRENCH LIEUTENANT’S WOMAN
Abstract This essay aims at investigating the significance of Jane Austen in John Fowles’s The French Lieutenant’s Woman. References to Austen’s Persuasion appear three times in Fowles’s novel, and the resonances of this intertextual dialogue substantially affect the politics of characterization and space (mainly the Cobb) in The French Lieutenant’

6. A IMPORTÂNCIA DAS CUMARINAS PARA A QUÍMICA MEDICINAL E O DESENVOLVIMENTO DE COMPOSTOS BIOATIVOS NOS ÚLTIMOS ANOS
Coumarins are natural products characterized as 2H-chromen-2-one, according to IUPAC nomenclature, largely distributed in plants, as well as, in species of fungi and bacteria. Nowadays, many synthetic procedures allow the discovery of coumarins with expanded chemical space. The ability to exert non-covalent interactions with many enzymes and receptors in liv

7. LABORATORY INVESTIGATION OF X-RAY PHOTOLYSIS OF METHANOL ICE AND ITS IMPLICATION ON ASTROPHYSICAL ENVIRONMENTS
Methanol (CH3OH) is one of the most abundant organic molecules in astrophysical environments. It has been found in cold regions such as surfaces of comets, ices near young stellar objects and protoplanetary disks, as well as in the gas phase in different regions in space. In this work, we experimentally simulate the methanol ice and its behavior when irradia

8. Using the Interval Metric for Modeling Entities Geometrics in ℝ2 - Case Study Interval Circumference
ABSTRACT The study of some distances provide science a way to separate two entities. It has applications in various fields such as remote sensing, data mining, pattern recognition and multivariate data analysis and others. If the distance is a Hausdorff metric, the guarantee is that all individuals are available. With the use of the distance of Trindade et a

9. Evaluation of the Influence of the Substituting Cation on the Structural and Morphological Properties of the New Garnet Sm3−xREExFe5O12 (REE = Dy, Gd and Lu)
Rare earth garnets (REE3Fe5O12) have magnetic-electric and optical properties that can be used in transmitters, microwave and data storage devices. These properties depend mainly on partial or total substitution of the cationic sites, as well as by the synthesis method used. Therefore, in this work was studied the influence of the substituting cation on the

11. Role-Play como Estratégia Pedagógica para Problematizar as Linhas de Cuidado Integral em Saúde aos Adolescentes e Jovens
RESUMO Diante da necessidade de integrar o debate de gênero e sexualidade à formação médica, uma unidade curricular de Saúde Coletiva de um curso de Medicina público federal propôs a metodologia da Aprendizagem Baseada em Projetos (ABPj) para essa formação. Nessa proposta pedagógica, os estudantes constroem um produto final como recurso para inter

12. O Sócrates de Hannah Arendt
Resumo: Com o fito de compreender as noções de história e juízo político, este artigo pretende mostrar a peculiar interpretação que Hannah Arendt faz da mais conhecida e discutida personalidade filosófica: Sócrates. Assim como outras ideias, tais como a de banalidade do mal, a natureza do terror totalitário e de espaço público, sua estrita pintur
