14. Diacetate Naphthoquinone Derivatives Tethered to 1,2,3-Triazoles: Synthesis and Cytotoxicity Evaluation in Caco-2 Cells
Acetylated compounds prepared from naphthoquinones have been reported as antitumoral prodrugs. Exploring the synthetic versatility of the naphthoquinone and triazolic nuclei, herein we report a simple and efficient synthetic route to prepare a series of sixteen prodrugs prototype of 1,2,3-triazoles-naphthoquinodoic acetyl derivatives. The compounds 10a-10h a

15. Synthesis and Anti-Chikungunya Virus (CHIKV) Activity of Novel 1,4-Naphthoquinone Sulfonamide and Sulfonate Ester Derivatives
Chikungunya virus (CHIKV) is a re-emerging disease caused by an alphavirus of the Togaviridae family. Since its first description in 1952, the disease has spread worldwide, affecting populations in both tropical and temperate countries. To date, there is no licensed vaccine or specific pharmacological treatment. Therefore, there is an increasing urgency in d

16. MAKING THE MATHEMATICAL WORLD: ON JULIAN COLE’S INSTITUTIONAL ACCOUNT OF MATHEMATICS*
Abstract Even though it is obvious that mathematics involves social activities, this rather trivial fact is rarely considered as important for its subject matter, mostly due to its undesired ontological consequences. An attempted solution for this tension was developed by Julian Cole’s institutional account of mathematics, named Practice- Dependent Realism

17. Bullous Melanoma: should the thickness of the bullous lesion be included in Breslow depth measurement?
Abstract Bullous melanoma represents a rare variant of melanoma, especially in patients without underlying bullous cutaneous disease. Few cases have been described in the literature, including cases of melanoma in patients with bullous epidermolysis or Hailey-Hailey disease. The histopathological diagnosis of bullous melanoma does not show any difficulties,

18. AUTÔMATOS SONHAM COM AMANTES CIBERNÉTICOS?
RESUMO: Neste artigo, que tem como suporte teórico o conceito de “paixão pelo autômato”, analisam-se duas ordens de produções culturais contemporâneas: em uma, desponta o enlace erótico entre humanos e robôs onde antes predominava o tema da guerra; em outra, sobressai a ideia da compatibilidade amorosa a priori entre humanos, a qual poderia ser c

19. Uncertain consumption practices in an uncertain future
Resumo Esta edição especial do Cadernos EBAPE.BR buscou provocar uma reflexão focada em práticas de consumo incertas em um futuro incerto. Enquanto pesquisas anteriores de marketing e consumo têm explorado práticas de consumo circunscritas em um contexto institucionalizado, conhecido e mais ou menos previsível, o conjunto de artigos aprovados nesta ed

20. Seleno- and Telluro-Functionalization of Quinones: Molecules with Relevant Biological Application
Quinones and organochalcogens are classes of compounds with great biological applicability, such as antioxidant, anticancer, anti-Alzheimer, and antidepressant activities, among others. Thus, the combination of these two classes of compounds is important to obtain new hits with biological activities that are additive or synergistic. Several methodologies for

21. A New Synthetic Route and Comprehensive Topological Study of a Benzimidazole Derivative
Benzimidazole and its derivatives are molecules that have diverse biological properties, therefore we synthesized and studied a new benzimidazole to understand their physical/chemical properties. The compound was obtained through a new synthetic route, using graphite oxide, in the absence of solvent, with crystalline packaging supported by C-H…N and C-H…

22. Na rua, no meio do redemoinho: das mediações de Exu no espaço público à ação político-ritual em dois contextos afro-religiosos
Resumo: Partindo de momentos etnográficos de escalas e durações variadas, que vão da sobrevida de uma árvore ancestral a uma grande peleia jurídica, este artigo analisa a agência de algumas pessoas, coisas e entidades em dois contextos afro-religiosos - um deles situado em Porto Alegre - RS e o outro, em Santo Amaro da Purificação-BA. O batuque e o

23. A obra madura de Lukács: sobre a correlação entre ética e ontologia
Resumo: Neste artigo, analisaremos a colocação da questão da ética em Lukács, explicitando que a correlação existente em sua obra entre ontologia e ética é distinta do que se pode imaginar de início. Trata-se de uma abordagem que, na esteira da ênfase na necessidade de renascimento do marxismo diante da permanência do stalinismo, enfatiza a impor

24. MIMO-PLC Communications in an Experimental Medium Voltage Network: Measurement and Analysis
Abstract This paper presents measurements at a mock-up medium voltage network to verify the feasibility of Broadband Power Line Communication (BPLC). We use the data extracted within the frequency range 2 − 30 MHz to characterize a MIMO PLC network using different phase combinations, defining the best and worst use case scenarios. The empirical data shows
