this study is aimed to identify sources of particulate matter with mean aerodynamic diameterbelow 10 μm (pm10) present in the atmosphere of the metropolitan area of mexico city (mamc), usingsamples obtained from january 1st to june 30th, 2009, analyzed with x-ray spectrometric techniques.minivol samplers were used to collect samples on polycarbonate filters in three sites (north, center, andsou...

SUMMARY Seismic inversion of amplitude versus offset (AVO) data in viscoelastic media can potentially provide high-resolution subsurface models seismic velocities and attenuation from offset/angle gathers. P- S-wave quality factors (Q), whose inverse represent a measure attenuation, depend on reservoir rock pore fluid properties, particular, saturation, permeability, porosity, viscosity litholo...

Okmok volcano located on the northeastern part of Umnak Island is one most active volcanoes in Aleutian Arc. It was initially built as a large shield volcano, but 12,000 and 2,050 years ago, it experienced two caldera-forming eruptions that destroyed central volcano. The post-caldera have occurred mostly along inner perimeter caldera from cinder tuff cones. Here, we use local earthquake data Al...

Dear Editor, Post-traumatic stress disorder (PTSD) is an anxiety disorder that can arise after exposure to a terrifying event/ordeal in which severe physical harm occurred or was about to happen. PTSD symptoms include persistent re-experience of the trauma, avo idance o f t rauma-assoc ia ted s t imul i , and hyperarousal. In the present report, we describe a woman with PTSD whose symptoms were...

The conventional Markov chain Monte Carlo (MCMC) method is limited to the selected shape and size of proposal distribution and is not easy to start when the initial proposal distribution is far away from the target distribution. To overcome these drawbacks of the conventional MCMC method, two useful improvements in MCMC method, adaptive Metropolis (AM) algorithm and delayed rejection (DR) algor...
