Geophysical and geothermal data are examined from the three southernmost sections of Chile Ridge, starting at 44°S continuing south to triple junction Nazca, Antarctic, South America plates 47°S. These represent progressively younger stages in a ridge‐trench collision event, corresponding 3 m.y. before collision, 1 culminating an ongoing junction. Magnetic bathymetric across Rise indicate that there is little change configuration spreading center as ridge approaches then collides with...

A new Chile ridge tectonic framework is developed based on satellite altimetry data, shipboard geophysical data and, primarily, 38,500 km of magnetic gathered a joint U.S.‐Chilean aeromagnetic survey. Eighteen active transforms with fossil fracture zones (FZs), including two complex systems (the FZ and Valdivia systems), have been mapped between the northern end Antarctic‐Nazca plate boundary (Chile ridge) at 35°S margin triple junction 47°S. spreading rates from 23 Ma to Present determined...

The Aburrá Valley, located in the northwestern region of Colombia, has undergone significant land cover changes and urban expansion recent decades, driven by rapid population growth infrastructure development. This region, known for its steep topography dense urbanization, faces considerable environmental challenges. Monitoring these transformations is essential informed territorial planning sustainable study leverages Synthetic Aperture Radar (SAR) imagery from Sentinel-1 mission, covering...

Objective. To evaluate the efficacy and safety of triple fixed-combination bimatoprost 0.01%/brimonidine 0.15%/timolol 0.5% (TFC) versus dual brimonidine 0.2%/timolol (DFC) in primary open-angle glaucoma ocular hypertension. Methods. Patients with intraocular pressure (IOP) ≥23 ≤34 mmHg were randomized to twice-daily TFC or DFC. The variable is change worse eye mean IOP from baseline at week 12 (modified intent-to-treat (mITT) population). Secondary endpoints are weeks 1, 2, 4, 8, (mITT...

The ability to estimate soil temperature (Ts) from satellite information is highly useful, since this one of the main input variables in various models designed for estimating biophysical parameters.A comparative analysis made Split-Window algorithms used data provided by Advanced Very High Resolution Radiometer (AVHRR) sensor on board satellites National Oceanic and Atmospheric Administration (NOAA).The compared are those proposed by: Prata Platt (1991); Uliveri et al. (1992); Sobrino...

To assess the efficacy and safety of patterned laser trabeculoplasty (PLT) as an adjunctive treatment in open angle glaucoma (OAG) or ocular hypertension (OHT) patients who were under antiglaucoma medical treatment.This study was a retrospective review primary secondary OAG OHT with medically uncontrolled (≥18 mm Hg) intraocular pressure (IOP) underwent 360° PLT from June 2016 to August 2016. Follow-up visits at week 1, 3 6mo performed. IOP, best corrected visual acuity (BCVA), complications...

Abstract We use a Generalized Watershed Loading Function (GWLF) model to simulate streamflow in the Gualí River Basin. The model's performance is assessed using metrics such as percentage of bias (PBIAS), Nash–Sutcliffe efficiency (NSE), RMSE–observations standard deviation ratio (RSR), and Kling–Gupta (KGE) indicate good performance. Furthermore, we analyze projections precipitation several global climate models (GCMs) from Coupled Model Intercomparison Project Phase 6 (CMIP6) three shared...

Extreme rainfall events in Andean basins frequently trigger landslides, obstructing river channels and causing flash flows, loss of lives, economic damage. This study focused on improving the modeling these to enhance risk management, specifically La Liboriana basin Salgar (Colombia). A cascading methodology was developed, integrating spatially distributed intensities, hazard zoning with SLIDE model, propagation RAMMS using calibrated soil rheological parameters, hydrological model TETIS,...

Environmental pollution indicated by the presence of PM2.5 particulate matter varies based on prevailing atmospheric conditions described certain meteorological variables. Consequently, it is important to understand behavior in areas such as Aburrá Valley, which experiences recurrent events twice a year. This study examines specific variables and Valley. By using statistical analysis tools correlation coefficients, principal component (PCA), multiple linear regression models, research...
