Experimental study on dynamic response of rock tunnel subjected to train moving load

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources, 2023
The tunnels might be suffered from damage and destruction under the dynamic loads generated by trains moving on the upper railways, which can in turn threaten the safety of the railways. Understanding the dynamic response of tunnel under the train moving

Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Geothermal electricity generation and desalination: an integrated process design to conserve latent heat with operational improvements [PDF]

open access: yes, 2016
A new process combination is proposed to link geothermal electricity generation with desalination. The concept involves maximizing the utilization of harvested latent heat by passing the turbine exhaust steam into a multiple effect distillation system ...

National Environmental Policies and Corporate Green Innovation: The Mirroring Versus Substitution Hypotheses

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Drawing on comparative institutional theory, we study the nature and magnitude of the effects of national environmental policies on corporate green innovation in developed versus emerging markets. Using a sample of 1831 listed firms in 34 countries from 2002 to 2020, we find that national environmental policies increase corporate green ...

Copper precipitation as consequence of steel corrosion in a flow-through experiment mimicking a geothermal production well

open access: yesGeothermal Energy, 2017
Decreasing production rates and massive precipitation of native copper (Cu(0)) were observed in the production well at the geothermal research facility Groß Schönebeck (Germany). The Cu precipitates filling up the well are a product of an electrochemical

Ranking the geothermal potential of radiothermal granites in Scotland: are any others as hot as the Cairngorms? [PDF]

open access: yes, 2017
Prior investigations concur that the granite plutons in Scotland which are most likely to prove favourable for geothermal exploration are the Ballater, Bennachie, Cairngorm and Mount Battock plutons, all of which have heat production values greater than ...

A Decision‐Making Model for Implementing Green Technology in Sustainable Building Projects

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Green technology (GT) adoption is pivotal for reconciling environmental stewardship with economic viability in the built environment, particularly in resource‐constrained emerging economies. However, empirical evidence on how specific GT drivers actively mitigate adoption barriers remains scarce.
