Reconstructing anthropic coastal landscape of Campi Flegrei volcanic area (Southern Italy) during the Roman period from multi-technique surveys

Journal of Maps, 2023
Campi Flegrei is one of the widest and most dangerous active volcanic complexes in the Mediterranean basin, known to be affected by continuous and sudden vertical ground movements (bradyseismic crisis) that have characterized the post-calderic volcanic ...

Evaluation of the Relative Tectonic Activity of the Yeşilyurt Fault Using Morphometric Analyses

Firat University Journal of Experimental and Computational Engineering
The Yeşilyurt Fault (YF) is an approximately 70 km long, NE–SW-trending, left-lateral strike-slip fault located in eastern Türkiye and constitutes a major structural element for assessing regional seismic hazard in Malatya Province. This study integrates multiple morphometric indices to quantitatively evaluate the spatial variability of tectonic ...

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system

Deep Underground Science and Engineering, EarlyView.
The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an

Assessment of the Tectonic Activity in Northwestern Part of the Zagros Mountains, Northeastern Iraq by Using Geomorphic Indices [PDF]

, 2019
The Tectonic Activity of regions with active tectonics can be assessed by using of the geomorphic indices. Six Geomorphic indices including stream-gradient index (SL), drainage basin asymmetry (Af), drainage basin shape (Bs), hypsometric integral (Hi ...

The damage and failure mechanism of prestatically loaded rock during medium‐strain rate cyclic impact loading

Deep Underground Science and Engineering, EarlyView.
Based on experimental results and theoretical analysis, an established rock damage accumulation model that comprehensively considers the preapplied static load, impact peak value, impact frequency, and impact times. Abstract To study the rock damage mechanism under high static loading and superimposed medium strain rate cyclic impact loading, a series ...

Assessment of active tectonic by using geomorphic indices in Dezful- Andimeshk basin

تحقيقات جغرافيايی, 2020
Aims and Backgrounds: Almost no area in the world can be found that has not been affected by tectonic processes. The morpho-tectonic indices of the basin are used to investigate the active tectonics.

Critical expansion points: Mechanical signs of surrounding rock instability

Deep Underground Science and Engineering, EarlyView.
This study proposes the Rock Bearing‐Expansion Model (RockBEM) with critical expansion points (CEPs) to quantify post‐peak damage stages in deep‐buried rock masses via plane strain compression test (PSCT). CEP hysteresis&interval ratios reveal bearing performance dynamics and failure severity, advancing mechanistic insights into deep underground rock ...
