Oppia Quadrangle Av-10 (288–360 E, ±22 ) is a junction of key geologic features that preserve a rough history of Asteroid (4) Vesta and serves as a case study of using geologic mapping to define a relative geologic timescale. Clear filter images, stereo-derived topography, slope maps, and multispectral color-ratio images from the Framing Camera on NASA’s Dawn spacecraft served as basemaps to cr...

conclusions the use of smoothing methods helps us to eliminate non-linear effects but it is more appropriate to use cox proportional hazards model in medical data because of its’ ease of interpretation and capability of modeling both continuous and discrete covariates. also, cox proportional hazards model and smoothing methods analysis identified that age at diagnosis and tumor size were indepe...

Velocity model estimation from seismic data using prestack depth migration is an un-derdetermined problem: there are many subtly diierent models which are not kinematically equivalent. As these models can give rise to dramatically diierent interpretations and decisions there is a clear need for a selection criterion in order to choose the "best" (i.e. geologically most plausible) one. Interpret...

This research focuses on the investigation of hydrogeological hazards in open pit coal mines. The study area is Amyntaio sub-basin area, located West Macedonia prefecture, Greece. A major part SE this occupied by mine. In recent decades, basin’s aquifer has been overexploited both dewatering wells mine and irrigation wells, triggering extensive land subsidence an that extends 3 km around Additi...

Abstract Recent scientific consensus suggests that climate-related disasters are becoming more frequent and destructive. Consequently, increasing importance is given to disaster risk reduction (DRR) climate change adaptation (CCA) in global governance. The projected warming at 1.5 ºC the variability Philippine archipelago experiences make DRR-CCA key priorities of both national local government...

Here, we investigated the crustal structure beneath eastern Anatolia, an area of high seismicity and critical significance for earthquake hazards in Turkey. The study was based on local tomography method using data from earthquakes that occurred provided by Turkiye Cumhuriyeti Ministry Interior Disaster Emergency Management Directorate Earthquake Department dataset used included travel times 54...

The development and application of luminescence dating dosimetry techniques have grown exponentially in the last several decades. Luminescence methods provide age control for a broad range geological archaeological contexts can characterize mineral glass properties linked to geologic origin, Earth-surface processes, past exposure light, heat, ionizing radiation. applicable spans 500,000 years o...

Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national s...
