1. SEQUENTIAL MULTI-ELEMENT DETERMINATION OF TRACE-METALS IN BIODIESEL SAMPLES USING HR-CS FAAS
In this work the feasibility of sequential multi-element determination of Zn, Fe, Mg, Cu, Na, K, Cr, Al and Ca in biodiesel samples by high-resolution continuum source flame atomic absorption spectrometry (HR-CS FAAS) was investigated. Biodiesel samples obtained from different sources and different chemical processes were analysed. The samples were diluted w

2. High-resolution CT pulmonary findings in children with severe asthma
Abstract Objective: To compare quantitative CT parameters between children with severe asthma and healthy subjects, correlating to their clinical features. Methods: We retrospectively analyzed CT data from 19 school-aged children (5-17 years) with severe asthma and 19 control school-aged children with pectus excavatum. The following CT parameters were eval

3. Synthesis of Sparse Arrays Based On CIGA (Convex Improved Genetic Algorithm)
Abstract In this paper, a novel hybrid algorithm on beam pattern synthesis of sparse arrays is proposed, which aims at minimizing the peak sidelobe level (PSLL). Sparse arrays can provide higher spatial resolution and relatively lower sidelobe than general arrays, but it is necessary to solve the multi-constraint problem of nonconvex nonlinear. Thus, we prop

4. Well Defined Rich Electronic Structure: Facile Approach for Nido-Carborane Fused Azaspirodecaniums in Water Solution
A novel bis-dumbbell shape of a multi cation around a azaspirodecanium combined with nido-carborane was prepared in a single step in good yield starting from pyrrolidine and 1,3-dichloropropane to give one compound and from piperidine and 1,4-dichlorobutane to give the other. This is the first report of an electrolyte azaspirodecanium-boron-cluster structure

5. O MBTI na Educação Médica: uma Estratégia Potente para Aprimorar o Trabalho em Equipe
RESUMO A assistência à saúde torna-se cada vez mais complexa, e as novas demandas exigem que as pessoas readaptem seus processos de trabalho para a construção de uma equipe multiprofissional que assegure integralidade, qualidade e efetividade do cuidado aos usuários do sistema de saúde. A Association of American Medical Colleges recomendou que os curr

6. Synthesis and Biological Evaluation of New Eugenol-Derived 1,2,3- Triazoles as Antimyco bacterial Agents
Eugenol has diverse biological properties including antimycobacterial activity, and the triazole ring is an important heterocycle in antimycobacterial compounds. Therefore, this research aimed to synthesize novel eugenol-derived 1,2,3-triazole as antimycobacterial agents with interesting cytotoxic profile and pharmacological assets. Sixteen compounds were ob

7. Análise do Método Multi-Passos com Transformada Diferencial Generalizada na Modelagem Fracionária
RESUMO Apresenta-se uma análise crítica de uma técnica numérica que tem sido usada na resolução de equações diferenciais de ordem fracionária com derivadas de Caputo. Trata-se do método multi-passos com transformada diferencial generalizada. Verifica-se que a versão do método disponível na literatura produz soluções erradas a partir do segundo

8. STOCHASTIC DISCRETE LOT-SIZING WITH LEAD TIMES FOR FUEL SUPPLY OPTIMIZATION
ABSTRACT We address the problem of expected cost minimization of meeting the uncertain fuel demand during a time planning horizon, where supply is provided by selecting discrete shipments with lead times. Due to uncertainty and the passage of time, corrective actions can be taken such as cancellation and postponement on supply of shipments with associated co

9. Long-term follow-up of tonsillectomy efficacy in children with PFAPA syndrome
Resumo Introdução: O papel da tonsilectomia na síndrome da febre periódica, estomatite aftosa, faringite e adenite é controverso. Embora alguns estudos tenham relatado altas taxas de sucesso com a tonsilectomia, são necessárias mais pesquisas com um número maior de pacientes. Objetivo: Avaliar os resultados em longo prazo da tonsilectomia na síndr

10. Favorability potential for IOCG type deposits in the Riacho do Pontal Belt: new insights for identifying prospects of IOCG-type deposits in NE Brazil
ABSTRACT: Archean iron oxide-copper-gold (IOCG) deposits have been systematically described in the world class Carajás IOCG district, Amazonian region of Brazil. More recently, several Neoproterozoic (ca 1.13 to 0.96 Ga) IOCG deposits have been identified in the Riacho do Pontal mobile belt situated in the Borborema Province on the northern border of the S�

11. Remote sensing of the chlorophyll-a based on OLI/Landsat-8 and MSI/Sentinel-2A (Barra Bonita reservoir, Brazil)
ABSTRACT In this present research, we assessed the performance of band algorithms in estimating chlorophyll-a (Chl-a) concentration based on bands of two new sensors: Operational Land Imager onboard Landsat-8 satellite (OLI/Landsat-8), and MultiSpectral Instrument onboard Sentinel-2A (MSI/Sentinel-2A). Band combinations designed for Thematic Mapper onboard L

12. ESTUDO DO SISTEMA VERTICAL DE REFERÊNCIA DO EQUADOR NO CONTEXTO DA UNIFICAÇÃO DO DATUM VERTICAL
O Equador e em geral os demais países da América do Sul, não dispõem de uma referência única para as altitudes. Cada país tem o Datum Vertical (DV) associado a uma superfície de nível obtida dos registros de um ou vários marégrafos. A relação entre os diferentes data verticais locais é condicionada, idealmente, pelas variações espaço-tempora
