25. Magnetic and Electrical Properties of MnxCu1-xFe2O4 Ferrite
In the present work, mixed manganese-copper ferrite of composition MnxCu1-xFe2O4 (within x=0.40, 0.42, 0.44, 0.46, 0.48 and 0.50) have been investigated for their electric and magnetic properties such as dc resistivity, Curie temperature, saturation magnetization. MnxCu1-xFe2O4 ferrite samples were prepared by uniaxial pressing from the oxide mixture, synthe

26. An Accurate Study on Capacitive Microphone with Circular Diaphragm Using a Higher Order Elasticity Theory
Abstract This study has been undertaken to investigate the mechanical behavior of the capacitive microphone with clamped circular diaphragm using modified couple stress theory in comparison to the classical one. Presence of the length scale parameter in modified couple stress theory provides the means to evaluate the size effect on the microphone mechanical

27. Combined treatment with caffeic and ferulic acid from Baccharis uncinella C. DC. (Asteraceae) protects against metabolic syndrome in mice
Fractionation of the EtOH extract from aerial parts of Baccharis uncinella C. DC. (Asteraceae) led to isolation of caffeic and ferulic acids, which were identified from spectroscopic and spectrometric evidence. These compounds exhibit antioxidant and anti-inflammatory properties and have been shown to be effective in the prevention/treatment of metabolic syn

28. Dielectric Behavior of Alginate-Based Hydrogel Containing Neomycin-Loaded Lipid Nanovesicles under Influence of Electrical Potentials
Dielectric characterization has been applied as a convenient tool for evaluation of transport and polarization mechanisms in soft materials. In this work, we have explored the study of charge transport mechanisms in alginate hydrogel containing neomycin-loaded liposomes. For comparison, drug release kinetic was evaluated by using UV-Vis spectrophotometry and

29. The rapid and sustained responses of dendritic cells to influenza virus infection in a non-human primate model
Dendritic cells (DCs) are readily infected by influenza viruses and play a crucial role in regulating host innate and adaptive immune responses to viral infection. The aims of this study are to characterize the dynamic changes in the numbers and maturation status of dendritic cells present in the lung and lung-associated lymph nodes (LALNs) in the model of a

30. Combination of the essential oil constituents citral, eugenol and thymol enhance their inhibitory effect on Crithidia fasciculata and Trypanosoma cruzi growth
We analyzed the effect of the combination of citral, eugenol and thymol, respectively the main constituents of essential oils of Cympobogon citratus (DC) Stapf, Poaceae (lemon grass), Syzygium aromaticum(L.) Merr. & L.M. Perry, Myrtaceae (clove) and Thymus vulgarisL., Lamiaceae (thyme), on the proliferation of the trypanosomatids Crithidia fasciculataand Try

31. Verificação da previsão do tempo em São Paulo com o modelo operacional WRF / Review of weather in São Paulo with the WRF Operational Model.
Forecasts of daily maximum and minimum temperatures and rainfall performed by the operational numerical weather prediction WRF (Weather Research Forecasting) model in the São Paulo are evaluated. Initial and boundary conditions provided by the 00UTC Global Forecast System (GFS) Model and WRF run for 72 hours, with two nested grids (with horizontal grid spac

32. The Poisson-exponential regression model under different latent activation schemes
In this paper, a new family of survival distributions is presented. It is derived by considering that the latent number of failure causes follows a Poisson distribution and the time for these causes to be activated follows an exponential distribution. Three different activationschemes are also considered. Moreover, we propose the inclusion of covariates in t

34. Investigação sobre compostos voláteis de espécies de Baccharis nativas do Rio Grande do Sul
The species of Baccharis spp. (Compositae) are an important source of research to investigation new active ingredients for medicinal natural products. Thus, this work presents a proposition of research on volatile compounds of three native species of Baccharis (Baccharis anomala DC, Baccharis dentata (Vell) G. M. Barroso and Baccharis uncinella DC) collected

The Repetitive Strain Injury / Work Related Musculoskeletal Disorders (LER / DORT) can arise in any field of activity; just there is a causal factor, ie, functions and jobs that expose workers to risk factors. These risk factors are present in the operator of the harvesting machinery activities. Throughout the workday upper limbs are highly required, necessi

Autoimmune diseases, such as Diabetes Mellitus type 1 (DM1), celiac disease (DC) and atopic dermatitis (DA), are multifactorial disorder elicited by a complex interplay of environmental, genetic and immunologic factors. Unfortunately, remains obscure all genetic factors involved on the onset of autoimmune diseases. The aim of our study was to propose an immu
