The Anatomical Record, EarlyView.Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Stress validation of finite element model of a small-scale wind turbine blade
Journal of Energy in Southern Africa, 2019 Wind turbine blades are the first mechanical part of a wind turbine that interacts with the wind and hence play a key role in wind power generation. It is important that the wind turbine blade is tested for structural integrity in accordance to design ...

Business Strategy and the Environment, EarlyView.ABSTRACT The present study applied the diffusion of innovation theory to investigate the rate of diffusion of renewable energy sources used by Europe's top professional football stadiums and the relationship with carbon neutrality. A discrete diffusion model estimated the diffusion of renewable energy to saturation, and a multivariate logistic ...

Business Strategy and the Environment, EarlyView.ABSTRACT The transition to a circular economy (CE) has become a strategic priority for firms, yet empirical assessments of corporate circularity remain fragmented and heavily dependent on structured indicators or self‐reported metrics. This paper proposes a novel, text‐based circularity index derived from mandatory non‐financial statements of large ...

Modeling the Risk of a Failed Wind Turbine Blade Impacting a Power Transmission Line [PDF]
, 2009 Wind turbine installations are generally situated in proximity to power transmission lines that integrate generated power into the grid. Failure of a wind turbine that results in a blade or blade fragment thrown from the rotor can result in impact with a

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes
Chemie Ingenieur Technik, EarlyView.A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,

Rotating turbine blade pyrometer [PDF]
, 1974 Non-contacting pyrometer system optically measures surface temperature distribution on rotating turbine blade, comprising line-by-line scan via fiber optic probe. Each scan line output is converted to digital signals, temporarily stored in buffer memory,

Energy Science &Engineering, EarlyView.This paper aims to provide a robust design approach for HAWTs operating in shear flow. This study fills a critical research gap by integrating BEM and vortex theories for blade design in non‐homogeneous inflow conditions. The authors of the paper made an effort to develop and test an experimentally unsophisticated model of a turbine working in shear ...
