Lithological and structural control on Italian mountain geoheritage: opportunities for tourism, outdoor and educational activities

Abstract

Mountain landscapes are generated by the interplay of endogenous and exogenous processes, whose reciprocal importance changes over times. The Italian relief reflects a high geomorphodiversity and an overview on iconic mountain landscapes, representative of the lithological-structural diversity of the Italian relief, is presented. The study cases, located along Alps and Apennines and in the Sardinia island, are exemplary for the comprehension of the role of the substratum in shaping mountain landscapes and of the deriving risk scenario. Moreover, mountain landscapes are characterized by a high potential for use in terms of: i) ideal open-air natural laboratories for multidisciplinary educational purposes including geological-geomorphological, historical and ecological topics; ii) possibility of specific outdoor activities that take advantage of outdoor sports (e.g., climbing, canyoning, speleology). These feasible and versatile opportunities favour the enhancement of such environments under different perspectives as well as the involvement of local communities and the socio-economic return deriving from mountain geoheritage management.

Reconstruction and appraisal of Akunu–Akoko area iron ore deposits using geological and magnetic approaches

Abstract

Geological mapping and magnetic methods were applied for the exploration of iron ore deposits in the Akunu–Akoko area of Southwestern Nigeria for the purpose of evaluating their geological characteristics and resource potentials. A proton magnetometer measures the vertical, horizontal and total magnetic intensities in gammas. The subsurface geology was interpreted qualitatively and quantitatively. The downward continuations and second vertical derivatives, the small-sized mineralised bodies and shallow features in the study area were mapped. The faults are trending in the following directions: NE–SW, NW–SE, N–S and E–W groups, while the iron ore mineralisation is structurally controlled by two major groups of fault trends, namely, the NE–SW and NW–SE; the N–S and E–W groups are mere occurrences that do not contribute to the structural control of the iron ore mineralisation in Akunu.

The upward continuation has a linear feature similar to the principal orientation of the regional faults, while Locations 2 and 3 have relatively high magnetic susceptibility zones; suspected to be iron ore deposits. The depths to the magnetic sources ranged from 25 m to about 250 m.

Performance of Fiber Optical Sensors in the Structure of Concrete Dams to Deal with the Impact Actions (Case Study: Seimare Dam)

Abstract

Due to the fact that dams are considered one of the strategic infrastructures of a country, it is very important to protect it against destructive acts. Accordingly, sensors were used at various points to record structural responses to the dam. Based on the questionnaires completed by experts, accuracy had the score of 3.8 so it was considered as the most important feature of the sensors and the optical fiber sensor with a mean score of 3.93 was selected as the best sensor type among the available ones. For this project, a questionnaire was prepared based on Likert scale and SPSS method was used in TOPSIS software. Then, Seimare concrete double curvature arch dam was simulated in ABAQUS 2017 software and the proper positioning of the sensors for optimum performance was determined based on Finite Element Method analysis and according to structural control criteria such as tension, displacement, strain, velocity and so one.

Active Displacement Control of Active Magnetic Bearing System

Abstract

The worldwide energy production nowadays is over 3400 GW while storage systems have a capacity of only 90 GW [1]. There is a good solution for additional storage capacity in flywheel energy storage systems (FES). The main advantage of FES is its relatively high efficiency especially with using the active magnetic bearing system. Therefore there exist good reasons for appropriate simulations and for creating a suitable magneto-structural control system. The magnetic bearing, including actuation, is simulated in the ANSYS parametric design language (APDL). APDL is used to create the loops of transient simulations where boundary conditions (BC) are updated based upon a “gap sensor” which controls the nodal position values of the centroid of the shaft and the current density inputs onto the copper windings.
