Puff Models for Simulation of Fugitive Hazardous Emissions in Atmosphere

Journal of Environmental Protection 2011年第2期2卷 154-161页

作者： Ledina Lentz Pereira Camila Pinto da Costa marco tullio vilhena Tiziano Tirabassi 不详

A puff model for the dispersion of material from fugitive hazardous emissions is presented. For vertical diffusion the model is based on general techniques for solving time dependent advection-diffusion equation: the ADMM (Advection Diffusion Multilayer Method) and GILTT (Generalized Integral Laplace Transform Technique) techniques. Both approaches accept wind and eddy diffusion coefficients with any restriction in their height functions. Comparisons between values predicted by the models against experimental ground-level concentrations (from Copenhagen data set) are shown. The preliminary results confirm the applicability of the approaches proposed and are promising for future work.

Comparison between Non-Gaussian Puff Model and a Model Based on a Time-Dependent Solution of Advection-Diffusion Equation

Journal of Environmental Protection 2010年第2期1卷 172-178页

A comparison between a non-Gaussian puff model and an advanced time-dependent model to simulate the pollutant dispersion in the Planetary Boundary Layer is presented. The puff model is based on a general technique for solving the K-equation, using the truncated Gram-Charlier expansion (type A) of the concentration field and finite set equations for the corresponding moments. The other model (named ADMM: Analytical Dispersion Multilayers Model) is an semi- analytical solution to the time-dependent two-dimensional advection-diffusion equation based on a discretization of the PBL in N sub-layers;in each sub-layers the advection-diffusion equation is solved by the Laplace transform technique, considering an average value for eddy diffusivity and the wind speed. A preliminary performance evaluation is shown in the case of continuous emission from an elevated source in a variable boundary layer. Both models were able to correctly reproduce the concentration field measured and so to be used as operative air pollution models.

Secundum atrial septal defect(ASD)repres-ents one of the most common congenital heart diseases,accounting for up to 10%of all congenital heart defects.It is often diagnosed in adulthood due to the absence of clinical symptoms.[1]By the age of 40 years,90%of untreated patients have symptoms of exertional dyspnea,fatigue,pal-pitation,sustained arrhythmia,or even evidence of heart failure.

Granular cell tumor (GCT) is a rare neoplasm that can occur in any part of the body, but mostly they are located intraorally. Its histogenetic origin remains controversial, but it probably arises from Schwann cells and is generally benign. The tumor is typically asymptomatic and appears as a nodule, with a relatively high predilection for the tongue. This article reports a case of a 72-year-old woman treated at the Center of Oral Diagnosis of the Fundação Hermínio Ometto Dental School. The patient presented with an asymptomatic nodule in the dorsal surface of the tongue for approximately 4 months. The patient was submitted to an excisional biopsy and histopatological examination revealed polyhedral cells with granular aspect. The immunohistochemical staining for S-100 presented strong reactivity, confirming the diagnosis of GCT. Finally, we made a concise discussion about the pathogenesis and fundamental clinico-pathological aspects of GCT making the differential diagnosis.
