1. Waves in magnetized dusty plasmas with variable charge on dust particles
We present results obtained in recent years for wave propagation in a magnetized dusty plasma, including variable charge of the dust particles, and using a kinetic approach. Two forms of the dielectric tensor are obtained, which can be used depending on the application to be done. This dielectric tensor is used in some applications, in order to study the imp

2. The dielectric tensor for dusty magnetized plasmas with variable charge on dust particles
We derive the dielectric tensor for multicomponent magnetized dusty plasmas, including the effect of capture of plasma electrons and ions by the dust particles. For propagation perpendicular to the external magnetic eld and Maxwellian distributions of electrons and ions, we obtain compact expressions for the components of the dielectric tensor, which can be

3. Spatial absorption of a magnetosonic wave in a dusty magnetized plasma
The dielectric tensor for a multicomponent magnetized dusty plasma, including the effect of capture of plasma electrons and ions by the dust particles, is rewritten in order to provide expressions more suitable for applications. We use this tensor to study the spatial absorption of a magnetosonic wave, including effects up to second order in the Larmor radiu

4. A new formulation for the dielectric tensor for magnetized dusty plasmas with variable charge on the dust particles
A kinetic approach to the problem of wave propagation in dusty plasmas, which takes into account the variation of the charge of the dust particles due to inelastic collisions with electrons and ions, is utilized as a starting point for the development of a new formulation, which writes the components of the dielectric tensor in terms of a finite and an infin

5. Prevalene of respiratory simptons among furniture factore workers, in Votuporanga-SP / Prevalencia de sintomas respiratorios entre trabalhadores da industria moveleira, da cidade de Votuporanga-SP
The occupational asthma, pneumoconioses and granulomatosis diseases are considered the main respiratory illness related with occupational exposure. In developed countries, they are well documented in databases of epidemiological surveillance that allow a detailed analysis of the morbid-mortality. In Brazil, the researches about these diseases are rare and th

6. Electrostatic waves in a Maxwellian dusty plasma with variable charge on dust particles
A kinetic formulation developed to analyze wave propagation in dusty plasmas, which takes into account the variation of the charge of the dust particles due to inelastic collisions with electrons and ions, is utilized to study the propagation and damping of electrostatic waves with wave number exactly parallel to the external magnetic field and Maxwellian di
