2. X-ray line profile analysis and magnetic and optical properties of FexZn0.95-xCr0.05O nanoparticles fabricated by sol-gel route
Abstract FexZn0.95-xCr0.05O nanoparticles have been obtained for the different concentrations of Fe ions by using the sol-gel method. The hexagonal wurtzite structure of all the samples was confirmed by Rietveld refined X-ray diffraction patterns. The addition of Fe ions decreased lattice constants a and c from 3.2487 to 3.2474 Å and 5.2043 to 5.2029 Å, re

3. Radially Periodic Metasurface Lenses for Magnetic Field Collimation in Resonant Wireless Power Transfer Applications
Abstract In this paper, a new procedure and topology of magnetic metasurface lens are proposed for improving the performance of Resonant Wireless Power Transfer systems. Firstly, three subwave-length unit cells are optimized in order to get negative magnetic permeability in the same frequency, each one with a different refractive index, and they are experime

4. Autoantibodies against desmoglein 2 are not pathogenic in pemphigus
Abstract Background Anti-desmoglein 1 and 3 autoantibodies justify acantholysis in pemphigus; however, the pathogenesis of anti-desmoglein 2 is hypothetical. Objective To compare the participation of desmogleins 1, 2 and 3 through the production of serum autoantibodies, and protein and gene expression in the skin/mucosa of patients with pemphigus foliaceus

5. Reactivity of sera from dogs living in a leishmaniasis-endemic area to the COOH-terminal region of cysteine proteinase B
ABSTRACT Cysteine proteinases are well-known virulence factors of Leishmania spp. with demonstrated actions in both experimental mouse infection and human infection. However, studies on these enzymes in canine leishmaniasis are scarce. Here, we show, for the first time, the reactivity of sera from dogs living in an endemic area to a recombinant protein from

6. Modelo de indução de osteoporose em coelhas - avaliação radiográfica
ABSTRACT In order to establish a bone loss induction model in rabbits to study osteoporosis, 18 rabbits underwent ovariectomy and received methylprednisolone 1mg/kg intramuscularly on alternate days for two weeks. Immediately before ovariectomy up to 42 days after methylprednisolone administration, radiographs of the right olecranon were taken in the mediola

7. Antibacterial Effects of Cuminum cyminum Extract Against Enterococcus Faecalis Biofilms From Clinical Isolates
Abstract Objective: To compare the antibacterial efficacy of Cuminum cyminum (cumin) extract and 2% chlorhexidine. Material and Methods: E. faecalis was isolated from non-vital teeth with chronic apical abscess. Samples were then bred in the ChromAgar medium. Subsequently, E. faecalis bacteria’s DNA extraction was performed. DNA was then amplified by con

8. Effect of Propolis on Streptococcus mutans Biofilm Formation
Abstract Objective: To evaluate the susceptibility of S. mutans during growth as a biofilm in the presence of different concentrations of propolis. Material and Methods: Three different concentrations of ethanolic extract of propolis (10%, 5%, and 2.5%) were used to evaluate its potential to attenuate the biofilm formation of S. mutans (ATCC 25175) on micr

9. DEVELOPING NEAR INFRARED SPECTROSCOPIC MODELS FOR PREDICTING DENSITY OF Eucalyptus WOOD BASED ON INDIRECT MEASUREMENT
ABSTRACT The objective of this study was to establish multivariate models for the prediction of wood basic density with reference to the values of average density of trees and near infrared (NIR) spectra measured in the breast height. The wood basic density of 39 Eucalyptus clones was determined in the laboratory by means of the mean longitudinal positions o

11. Effect of Solid Solution Temperature on Microstructure and Corrosion Resistance of CoNiCrMo Alloy
Influence of solid solution temperature on microstructures and corrosion properties of CoNiCrMo alloy were investigated by means of optical microscopy (OM), scanning electron microscope (SEM) and electronic differential system. The corrosion resistance of CoNiCrMo alloy in 0.9%NaCl aqueous solution was also investigated. The results indicated that with the i

12. Effect of Ca Content on Properties of Extruded Mg-3Zn-0.5Sr-xCa Alloys for Medical Applications
Mg-3Zn-0.5Sr-xCa(wt.%) (x=0, 0.2, 0.5) alloys were fabricated by casting and hot extrusion. X-ray diffraction (XRD) and optical microscopy observation showed that the microstructure of Mg-3Zn-0.5Sr-xCa alloys was composed of α-Mg matrix and Mg17Sr2 phase precipitated along grain boundaries. The tensile strength of the alloy increased from 255MPa to 305MPa w
