13. Application of Nickel Ferrite Nanoparticles in Adsorption of Amoxicillin Antibiotic
According to the World Health Organization, amoxicillin (AMX) is the most widely consumed antibiotic in the world. Consequently, there is great interest in the development of new technologies that allow the removal of this type of contaminant, as exposure to antibiotic residues can cause a variety of adverse effects, such as toxicity and antimicrobial resist

14. Epidemiological monitoring of leprosy indicators in Sergipe (2001-2015): segmented regression analysis,
Abstract This study analyzed the trend of leprosy indicators in Sergipe, between 2001 and 2015. It was a time series study that analyzed the trend for general detection coefficient, children under 15 years of age, and new cases with grade 2 disability. The joinpoint model was used. Two (2.6%) municipalities had an increasing trend in general detection coeffi

15. A Novel Tri-bandpass Filter Side-coupled Square Ring Based
Abstract This work presents the design of a tri-bandpass filter based on the side-coupled square ring structure. The modeling is conceived from the classic approach of coupled transmission lines. The geometry consists of a square structure of electrical length equal to twice the wavelength of the main operating frequency, and the laterally coupled lines thro

16. Chitosan-Sodium Alginate Polyelectrolyte Complex Coating Pluronic® F127 Nanoparticles Loaded with Citronella Essential Oil
Pluronic® F127 nanoparticles were loaded with citronella essential oil (CEO) and then covered with chitosan-sodium alginate polyelectrolyte complex (PEC). The system was characterized according to size, zeta potential and stability over time. Dynamic light scattering (DLS) in different proportions of water/ethanol as a dispersive medium was important in con

17. Dexmedetomidine attenuates P2X4 and NLRP3 expression in the spine of rats with diabetic neuropathic pain
Abstract Purpose: To evaluate the effects of Dexmedetomidine (Dex) on spinal pathology and inflammatory factor in a rat model of Diabetic neuropathic pain (DNP). Methods: The rats were divided into 3 groups (eight in each group): normal group (N group), diabetic neuropathic pain model group (DNP group), and DNP model with dexmedetomidine (Dex group). The r

18. Pré-Despacho de um Sistema Hidrotérmico com Manobras e Restrições de Rampa
RESUMO. Os métodos de pontos interiores primais-duais foram utilizados para o problema de minimização do custo de operação do pré-despacho DC de um sistema de potência hidroelétrico e hidrotérmico onde ocorrem adicionalmente manobras programadas e restrições de rampa. Com a variação da demanda, se faz necessário realizar algumas manobras progra

19. ERROR BEHAVIOR OF ATOMIC CLOCKS ABOARD GPS SATELLITES
Abstract: The signal transmission and position quality obtained by GNSS positioning directly depends on the time control. The atomic clocks aboard the satellites are responsible for this control. In this research, the satellites clock errors of GPS are studied, using data from the pseudorange, the satellite semi-major axis and the correction parameters of th

20. HIV-1 mother-to-child transmission in Brazil (1994-2016): a time series modeling
Abstract HIV-1 mother-to-child transmission (HIV-1 MTCT), is an important cause of children mortality worldwide. Brazil has been traditionally praised by its HIV/Aids program, which provides free-of-charge care for people living with HIV-1. Using public epidemiology and demographic databases, we aimed at modeling HIV-1 MTCT prevalence in Brazil through the y

21. HYDROXYAPATITE - CARBON NANOTUBE COMPOSITES FOR DRUG DELIVERY APPLICATIONS
Abstract The aim of this study was the synthesis of composites containing hydroxyapatite (Hap) or silicon substituted hydroxyapatite (HapSi), carboxyl functionalized carbon nanotubes (fMWCNT) and gelatin (G) in different ratios. Ibuprofen (IBU) was chosen as a model drug for the formulation of extended-release dosage forms. The obtained composites were chara

22. Assessing the Impact of Prophylactic Vaccines on HPV Prevalence
RESUMO Um modelo matemático á proposto para avaliar as estratégias de controle da transmissão do HPV na população humana (homens e mulheres). O número reprodutivo básico da doença, R 0, é dado pela média geométrica do número reprodutivo básico obtido nas populações femininas e masculinas. O modelo tem um equilíbrio livre da doença globalmen

23. Armadillos and leprosy: from infection to biological model
ABSTRACT Mycobacterium leprae is the primary causative agent of Hansen’s disease or leprosy. Besides human beings, natural infection has been described in animals such as mangabey monkeys and armadillos. Leprosy is considered a global health problem and its complete pathogenesis is still unknown. As M. leprae does not grow in artificial media, armadillos h

24. Simulador didático para análise dos transientes de ondas de tensão em uma linha de transmissão similar à transmissão e reflexão de ondas eletromagnéticas
Abstract O modelo de educação nas últimas décadas passou por mudanças consideráveis do ponto de vista didático. Com o avanço da tecnologia, a velocidade de obtenção de informações aumenta e o uso de ferramentas que permitem a visualização dinâmica de conteúdos torna-se um forte aliado ao processo de ensino-aprendizagem. Este trabalho trata da
