1. AVALIAÇÃO ESPACIAL E SAZONAL DAS CONCENTRAÇÕES DE PARTÍCULAS TOTAIS EM SUSPENSÃO E ELEMENTOS METÁLICOS ASSOCIADOS NO AR DE UMA CIDADE DO SUDESTE BRASILEIRO
The present study evaluated the concentrations of Total Suspended Particles (TSP) and associated metals in three distinct regions of Ribeirão Preto city (Center City, Campus and Airport) in the dry and rainy seasons. There were no significant differences (p < 0.05) in TSP and metals concentrations between the sampling sites, except for Cu, Cr and Zn. Season

2. Chemical composition modulates the adverse effects of particles on the mucociliary epithelium
OBJECTIVE:We compared the adverse effects of two types of real ambient particles; i.e., total suspended particles from an electrostatic precipitator of a steel mill and fine air particles from an urban ambient particulate matter of 2.5 µm, on mucociliary clearance.METHOD:Mucociliary function was quantified by mucociliary transport, ciliary beating frequency

3. Estudo do fluxo de deposição de partículas para a Região Metropolitana da Grande Vitória usando dados de partículas totais em suspensão
A maior parte dos trabalhos científicos sobre a presença de material particulado na atmosfera está relacionada a partículas mais finas (menores que 2,5 μm ou menores que 10 μm), devido a seus efeitos sobre a saúde pulmonar dos seres humanos. Entretanto, partículas maiores podem causar consideráveis incômodos à população, devido a sua dep

4. Avaliação da qualidade do ar em ambientes internos: biblioteca pública / Indoor air quality investigation: public library
Over fifteen months, levels of temperature, humidity, noise, light intensity, contamination by carbon dioxide, total suspended particles (TSP) and respirable fractions (PM1, PM2.5, PM7 and PM10) were monitored at the Public Library Amadeu Amaral at São Carlos, SP. Investigation of the ventilation rate and occupancy, concentration of bioaerosols and identifi

5. Um Estudo da Qualidade do Ar na Cidade de Fortaleza. / A Study of Air Quality in the city of Fortaleza.
The quality of life for people around the world has a direct relationship with the ambient air quality, resource essential to life. Population growth in urban centers has contributed profoundly to the increased emission of pollutants into the atmosphere, mainly by burning fossil fuels and other actions of anthropogenic nature. Cities like Tokyo, Beijing, New

6. Project and assembling of pneumatic transport pilot unit in diluted phase for studying the relationship between the pressure drop and the distribution of granular particles into the cross section of industrial pipes / Projeto e montagem de unidade piloto de transporte pneumatico em fase diluida para estudo da relação entre a perda de carga e a distribuição de particulas granulares na seção transversal de dutos industriais
The pneumatic transport that involves the use of air particles to move materials through pipes is a major operation in various industries and chemical processes. Typical examples are systems for the conversion of energy from coal, catalytic cracking, drying and transport of solid and fine granular. The conventional pneumatic transport is often operated in di

7. Desempenho da Tecnologia de Filtração em Múltiplas Etapas (FiME) no Tratamento de Águas de Abastecimento em Escala Piloto / Performance technology Multi-Stage Filtration (MSF) for supplying water treatment on a pilot scale
The present work has evaluated the efficiency of an MSF system for treating supplying water on a pilot scale. A MSF pilot plant was located in the Water Treatment Station (WTS) area in Goianápolis- GO and fed by Sozinha stream. The plant was comprised of a dynamic prefilter (DPF) and a vertical upflowing pre-filter (VUF) in layers, both of them with differe

8. Processos dinÃmicos e evolutivos da zona costeira de Itamaracà por sensoriamento remoto e medidas in situ
The coastal zone of Itamaracà is like a highly dynamic environment where land and oceanic processes interact altering frequently coastal characteristics. In this context, this current study examines the responsible processes of such changes from the development and application of methodologies, which includes digital image processing and the obtaining of in

9. Composição elementar do material particulado presente no aerossol atmosférico do município de Sete Lagoas, Minas Gerais
The main objective of this study was the identification of sources generating particulate matter in the atmospheric aerosols of Sete Lagoas, Minas Gerais. The measurement of the mineral composition was accomplished by X-ray diffractometry and the elemental concentration by neutron activation analysis. The results showed that Al, Cl, Cu, Fe, K, Mg and Na are

10. Exposição aguda ao material particulado total em suspensão proveniente de diferentes fontes e suas repercussões nas respostas inflamatórias, sistêmica e local, em ratos / Acute exposure to total suspended particles from different sources and their impacts on both systemic and local inflammatory responses in rats
Background: Air pollution is associated with both increased morbidity and mortality. These associations persist even at lower concentrations and shortterm exposure. Objectives: To assess the impact of the components of three different sources of Total Suspended Particles (TSP) on local and systemic inflammatory responses in healthy rats. Methods: TSP from au

11. Um estudo sobre a qualidade do ar de Uberlândia : material particulado em suspensão
The city of Uberlândia is one of the most populous of Minas Gerais State, and has the second greatest fleet of motor-vehicles of the State. The motor-vehicles are responsible for a great amount of pollutants emitted to the atmosphere. The vehicular pollution added to the diverse sources of existing pollutants, including from industries, speeds up the concer
