Water Governance Under International Pressure: Policy Narratives, Food Security, Scarcity, and the Politics of Survival in Iran

Environmental Policy and Governance, EarlyView.
ABSTRACT Water governance is increasingly influenced by a paradox at the nexus of environmental scarcity and food security. Escalating water scarcity crises coincide with geopolitical disruptions that have exposed the fragility of global food supply chains, prompting states to expand domestic food production at the expense of water conservation ...

Innovation structures of very lean roller compacted concrete dams

Structural Mechanics of Engineering Constructions and Buildings, 2021
Over the past 20 years, rolled compacted concrete (RCC) dams have continued to be built in many countries because of their technical and economic advantages over conventional dams of vibrating concrete and embankment dams.

Civil Society Advocacy and Climate Change in Kenya: The Question of “Local Voices” and Their “Amplification”

Environmental Policy and Governance, EarlyView.
ABSTRACT The role of civil society organizations (CSOs) in addressing climate change is acknowledged, but engagement with questions of voice remains limited, especially in the Global South. Addressing this, this paper zooms in on (International) nongovernmental organizations ((I)NGOs) and their collaborations with domestic CSOs in the Global South on ...

From a Probabilistic PBEE Framework to Risk‐Targeted Structural Design With Cascading Hazards: Engineering Application for Seismic–Radiological Safety

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Earthquake‐induced damage of structures can trigger cascading hazards, linking structural performance to nonstructural consequences. In current engineering practice, these two aspects are typically addressed separately, limiting the ability to account for such coupled effects in design.

Horizontal and Vertical Movement of Concrete Dam Erecting on Sandy Soil under Seismic Loading

Diyala Journal of Engineering Sciences
Concrete dams are the strongest dams, designed for flood control, electricity generation, and water management. They can become unstable due to ground shaking and earthquake impacts, resulting in stability loss due to embankment and foundation materials

Maximum Entropy Method for Operational Loads Feedback Using Concrete Dam Displacement

Entropy, 2015
Safety control of concrete dams is required due to the potential great loss of life and property in case of dam failure. The purpose of this paper is to feed back the operational control loads for concrete dam displacement using the maximum entropy ...

Modeling the Nexus Between Climate Risk, Energy Consumption, and Financial Market Performance in Emerging Countries

International Studies of Economics, EarlyView.
Abstract This paper examines the link between climate risk, energy consumption, and financial market performance in a sample of emerging countries over the period 2000–2024. The objective is to model the dynamic interactions between these three dimensions, in order to understand the extent to which energy dependence and exposure to climate risks ...

Perceived Educational Value of a Self‐Developed 3D‐Printed Pediatric Dentistry Simulator

Journal of Dental Education, EarlyView.
ABSTRACT Purpose To design and assess a 3D‐printed pediatric dentistry simulator and to evaluate its perceived educational value and realism through student and expert feedback. Methods A maxillary simulator that is mountable on phantom heads was developed and produced by desktop stereolithography with single‐use inserts, enabling proximal caries ...

Level evaluation of concrete dam fractures based on game theory combination weighting-normal cloud model

Frontiers in Materials
Hazard evaluation of concrete dam fractures is vital for safe operations. The width (S1), length (S2), and depth (S3) of fractures are adopted as the assessment index, and the game theory combination weighting-normal cloud model is introduced. The normal

The German Soil Systematics and the Rationale Behind Its Revision

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background The German Soil Systematics is a pedogenetic classification based on the morphological expressions of pedogenic processes and has been developed over several stages since 1952. The system has successfully been in use for soil classification and soil survey for almost 70 years.
