1. Tunable Magnetic and Electrical Properties of Cobalt and Zinc Ferrites CO1-XZnXFe2O4 Synthesized by Combustion Route
Co and Zn ferrites with general formula CO1-XZnXFe2O4 (x = 0; 0,2 and 0,8) were synthesized by combustion reaction method, using urea as fuel. The structure of inverse-spinel-type ferrite were characterized through XRD using Rietveld refinement method to identify, quantify phases and determine lattice parameters. The crystallites had mean size of 37,33 nm, 4

2. Experimental vibration analysis for a 3D scaled model of a three-floor steel structure
In this paper we present an experimental study of a three dimensional physical model of a three-floor structure subjected to forced vibrations by imposing displacements in its support. The aim of this work is to analyze the behavior of the building when a dynamic vibration absorber (DVA) is acting. An analytic simplified analysis and a numerical study are de

4. Adverse effects on dental surgeons? health and its correlations with motor equipment use / Efeitos adversos na saúde de cirurgiões-dentistas e suas correlações com o uso de equipamentos motores
This study aimed to identify adverse effects reported by dental surgeons (DS) and correlate them to the use of motor equipment. We carried out a non experimental cross-sectional research with quantitative data analysis. The study involved 247 DS who work in Ribeirão Preto, Brazil. A self-applied questionnaire was used to assess the professionals. This instr

6. Efeito de esforços vibracionais na estrutura do tecido vegetal
The present work aims to study the effects of cyclic loading on selected mechanical properties of vegetative tissues. Farm machinery operations involved in all agricultural processes since seedling up to harvesting, transportation, packaging and storage is here considered as a potential generators of vibrating loading. Experiments were carried out on specime

7. Secagem de fatias de cebola em leito vibro-fluidizado / Drying of slices of onion on Vibro-fluidized bed
A prototype of a vibro-fluidized bed dryer was developed and applied to the dehydration of onion rings. Compared to conventional drying methods, this equipment reduces the drying time and improves the quality of the final product.The best vibrating parameters, in terms of energy consumption were determined. Special attention is given to the destription of th
