1. Performance evaluation of nebulizers based on aerodynamic droplet diameter characterization using the Direct Laminar Incidence (DLI)
Abstract Introduction Optical microscope images can be useful to evaluate nebulizers considering the size of droplets produced by these devices. From this perspective, the proposed method was compared to the classic concept of Mass Median Aerodynamic Diameter (MMAD) for the ideal droplet size between 0.5-5.5 µm. Methods We tested a sample of five home neb

2. Modelagem multicriterial aplicada a problemas de regulação em áreas portuárias privatizadas
O objetivo deste trabalho é apresentar uma proposta de modelagem multicriterial aplicada a problemas de regulação em áreas portuárias privatizadas, tratando da hierarquização de áreas com fins de rateio de investimentos em questões de arrendamento. Os métodos multicriteriais de análise de decisão (MMAD) mostraram-se mais apropriados para a modela

3. AEROSOL CHARACTERIZATION IN A REGION WITH HIGH CONCENTRATION OF MINERAL SANDS. / CARACTERIZAÇÃO DE AEROSSÓIS EM UMA REGIÃO RICA EM AREIAS MONAZÍTICAS.
The main deposit of mineral sands in Brasil occur from the Rio Grande do Norte State to Rio de Janeiro State. The main commercial deposit is located in Buena, a village at São Francisco de Itabapoana, Rio de Janeiro State. In buena there is a plant that process minerals sands to obtain ilmenite, zirconite, rutile and monazite concentrates. This plant belong

4. Aerodynamic particle size analysis of aerosols from pressurized metered-dose inhalers: Comparison of andersen 8-stage cascade impactor, next generation pharmaceutical impactor, and model 3321 aerodynamic particle sizer aerosol spectrometer
The purpose of this research was to compare three different methods for the aerodynamic assessment of (1) chloroflurocarbon (CFC)-fluticasone propionate (Flovent), (2) CFC-sodium cromoglycate (Intal), and (3) hydrofluoroalkane (HFA)-beclomethasone dipropionate (Qvar) delivered by pressurized metered dose inhaler. Particle size distributions were compared det

5. Aerosol generation by metered-dose inhalers containing dimethyl ether/propane inverse microemulsions
Water soluble compounds were incorporated into metered-dose inhalers (MDIs) by using water-in-propellant lecithin microemulsions, in which dimethyl ether (DME) and propane acted as both continuous phase and propellant. Lecithin, water, and water soluble compounds were added to glass MDI containers, valves were crimped on, and propellants were added using a p

6. Supercritical assisted atomization: A novel technology for microparticles preparation of an asthma-controlling drug
The objective of this study was to produce microparticles of a new asthma-controlling drug by supercritical assisted atomization (SAA), proposed as an alternative to conventional jet-milling process. SAA is based on the solubilization of supercritical carbon dioxide in a liquid solution containing the drug; the ternary mixture is then sprayed through a nozzl

7. Initial Characterization of Micafungin Pulmonary Delivery via Two Different Nebulizers and Multivariate Data Analysis of Aerosol Mass Distribution Profiles
Pharmaceutical aerosols have been targeted to the lungs for the treatment of asthma and pulmonary infectious diseases successfully. Micafungin (Astellas Pharma US, Deerfield, IL, USA) has been shown to be an effective antifungal agent when administrated intravenously. Pulmonary delivery of micafungin has not previously been reported. In the present pilot stu

8. Determinant factor for clearance of ceramic fibres from rat lungs.
Deposition, clearance, retention, and durability of inhaled particles from lungs are known to be important factors for induction of pulmonary fibrosis or lung cancer. To study the deposition and clearance of alumina silicate ceramic fibres from the lung, male Wistar rats were exposed to ceramic fibre particles with a mass median aerodynamic diameter (MMAD) o
