Dynamics of dissolved major (Na, K, Ca, Mg, and Si) and trace (Al, Fe, Mn, Zn, Cu, and Cr) elements along the lower Orinoco River

Autor: Juan Carlos Baquero, Alain Laraque, Daniel Pisapia, Abrahan Mora, Juan A. Alfonso, Jürgen Mahlknecht, Laura Balza

Publikováno v: Hydrological Processes. 31:597-611

This study addresses the changes in dissolved major and trace element concentrations along the Orinoco River, including the mixing zone between the Orinoco and Apure rivers. Water samples from the Apure and Orinoco rivers were collected monthly in fo

The Apure River: geochemistry of major and selected trace elements in an Orinoco River tributary coming from the Andes, Venezuela

Autor: Juan Carlos Baquero, Juan A. Alfonso, Abrahan Mora, Laura Balza, Daniel Pisapia

Publikováno v: Hydrological Processes. 24:3798-3810

The analysis of physicochemical variables and selected dissolved elements was performed on the Apure River waters for 15 months. The variables pH, alkalinity, dissolved O2, conductivity and Na, Ca, Mg and Cd concentrations showed maximum values durin

Impact of the Red Mud Disposal on Several Floodplain Lagoons of the Lower Orinoco River

Autor: Nirson González, Helga Handt, Daniel Pisapia, Juan A. Alfonso, Abrahan Mora, Cristina Moreau, Luisa Márquez, Yaneth Vásquez

Publikováno v: Water, Air, & Soil Pollution. 226

This paper identifies the effects of red mud spills on several lagoons of the Orinoco River located surrounding the red mud deposits. Chemical and mineralogical analyses of sediments indicate that the geochemical signature of red mud is evident in Lo

[Flexible Fiberoptic Bronchoscopy in children with persistent atelectasis: a case series report]

Autor: Hernán Lucio, Talamoni, Néstor Daniel, Pisapia, Jefferson Antonio, Buendía

Publikováno v: Archivos argentinos de pediatria. 113(2)

Most patients with pulmonary atelectasis have complete resolution with medical therapy. In patients with persistent atelectasis, endoscopic treatment has proven to be an effective therapy.To describe our experience using flexible fiberoptic bronchosc
