Seismic analysis of masonry gravity dams using the discrete element method: Implementation and application [PDF]

open access: yes, 2015
Much research in recent years has focused on the seismic analysis of concrete and earthfill dams, and few works have addressed the case of masonry dams. The structural behaviour of masonry dams is controlled essentially by its discontinuous nature, which

Institutional Ownership and Corporate Sustainability Performance—A Meta‐Analysis

open access: yesBusiness Strategy and the Environment, Volume 35, Issue 4, Page 4719-4735, May 2026.
ABSTRACT This study investigates the relationship between institutional ownership (IO) and corporate sustainability performance (SP), addressing inconsistent findings in prior research and clarifying the boundary conditions of this relationship by testing a defined set of potential moderators.

EFFECTIVE SEDIMENT CONTROL IN A RESERVOIR [PDF]

open access: yes, 2014
Sedimentation in a reservoir cannot be avoided. The average rate of sedimentation on the storage volume reduction of a reservoir in the world is about 1 % per year (Yoon,1992), meanwhile, the storage volume reduction in several reservoir in Indonesia ...

Mass Screening in Modified Gravity

open access: yes, 2007
Models of modified gravity introduce extra degrees of freedom, which for consistency with the data, should be suppressed at observable scales. In the models that share properties of massive gravity such a suppression is due to nonlinear interactions: An ...

Measuring the foaminess of space-time with gravity-wave interferometers [PDF]

open access: yes, 2000
By analyzing a gedanken experiment designed to measure the distance $l$ between two spatially separated points, we find that this distance cannot be measured with uncertainty less than $(ll_P^2)^{1/3}$, considerably larger than the Planck scale $l_P$ (or

Seismic Fragility Analysis of Containment Structures in Nuclear Power Plants Considering Alkali‐Silica Reaction

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1467-1487, May 2026.
ABSTRACT This study quantifies the influence of alkali‐silica reaction (ASR) on the seismic fragility of prestressed concrete containment structures in nuclear power plants (NPPs). Global collapse was considered as the governing failure mode to maintain consistency with current risk assessment frameworks, and was captured using a finite element model ...
