1. Simultaneous Quantification of Amorphous and Crystalline Valsartan in Tablets Using Raman Spectroscopy and Chemometrics Tools
Valsartan is an antihypertensive active pharmaceutical ingredient (API), it is used in the amorphous state in the commercial products. As amorphous materials are metastable, amorphous valsartan can crystallize to valsartan E, promoting changes in the dissolution and bioavailability of the drug. Tablets containing metastable forms of APIs need special conditi

2. PROCESS-BASED ENTITIES ARE RELATIONAL STRUCTURES. From Whitehead to Structuralism
Abstract The aim of this work is to argue for the idea that processes and process-based entities are to be modelled as relational structures. Relational structures are genuine structures, namely entities not committed to the existence of basic objects. My argument moves from the analysis of Whitehead’s original insight about process-based entities that, de

3. Thermoelectric properties of barium doped calcium cobaltite obtained by simplified chemical route
Abstract Calcium cobaltite (CCO) thermoelectric ceramics in Ca3Co4O9 and Ca2.95Ba0.05Co4O9 compositions were produced by a simplified chemical route developed in this study. Undoped ceramics sintered at 1193 K for 12 h presented a bulk density equivalent to 77% of the theoretical density, one of the highest values ever found for conventionally sintered undop

4. Wide Band Stop Response Using Interdigital Capacitor/CSRR DGS in Elliptical Microstrip Low-Pass Filter
Abstract In this paper, a compact elliptic-response microstrip low pass filter (LPF) is presented with a wide stop-band using stepped impedance resonators. With high attenuation in the stop-band, the overall size reduction of the proposed filter is achieved using a novel defected ground structure technique using an interdigital capacitor and complementary sp

5. REGRESSÃO MULTIVARIADA POR OPLS E PLS DOS ESPECTROS DE RMN DE 1H DE MISTURAS DIESEL/BIODIESEL DE MAFURRA PARA ESTIMATIVA DO TEOR DE BIODIESEL
Two methodologies were developed to monitor the biodiesel content of mafurra in mixtures with diesel using hydrogen nuclear magnetic resonance (1H NMR) Spectroscopy combined with the multivariate regression by orthogonal projections to latent structure (OPLS) and partial least squares (PLS). The efficiency of these methodologies was analyzed based on the fig

6. Study of the Potential of Photovoltaic Microgeneration and Minigeneration from the Grid-Connected Photovoltaic Systems Installed at UTFPR Curitiba Campus
Abstract: Humanity is increasingly dependent on energy, which demand grows every year. Renewable energy sources are consolidated alternatives in the market, previously installed on a small scale but now thought as large plants. The correct operation, taking full advantage of the generation potential, depends on studies of the place of implantation, such as r

8. Practicability of somatic cell count and electrical conductivity as subclinical mastitis diagnostic tests in camels (Camelus dromedarius)
ABSTRACT Critical gaps exist in our understanding of the diagnostic reliability of subclinical mastitis tests in dromedary camels. Using a retrospective longitudinal cross-sectional approach, 191 lactating camels were randomly sampled from 47 camel herds to investigate at first the practicability of somatic cell count (SCC) and electrical conductivity (EC) t

9. El Juicio Subjetivo sobre las Desigualdades Sociales: ¿Qué Principios de Justicia se Aplican?
RESUMO Este artigo estuda as avaliações subjetivas da justiça social no Chile, um país em que prevalecem pronunciadas desigualdades sociais, como nos outros países da América Latina. Analisamos empiricamente as percepções sobre o justo e o injusto em relação ao salário para distintas posições sociais, procurando responder à pergunta sobre quais

10. Programa Mais Médicos sob o olhar dos usuários: uma pesquisa avaliativa
Resumo O Programa Mais Médicos (PMM) surge em 2013 como medida para enfrentar a ausência de médico na atenção básica. Gerou polêmicas na sociedade diante da abertura do mercado brasileiro para profissionais estrangeiros, com desaprovação por parte da categoria médica, mas com aparente aceitação popular. Assim, este estudo objetivou avaliar a impl

11. “Inclusão com mérito” e as facetas do racismo institucional nas universidades estaduais de São Paulo
Resumo As universidades estaduais de São Paulo estão entre as últimas universidades públicas brasileiras a introduzirem, nos seus processos seletivos, o sistema de reserva de vagas étnico-raciais, mais de uma década depois da primeira universidade a implementar o sistema. Mesmo diante de um quadro gritante de desigualdade racial de acesso à educação
