Performance of LLBC-based rotor blade for low speed wind turbine

open access: yesMATEC Web of Conferences, 2018
The development of wind turbine attracts more attention as a renewable energy that supports green technology. Layer Laminated Bamboo Composite (LLBC) is a bio-composite with bamboo base material which is abundant material and has a relatively lower price.

Multiobjective Optimization of Composite Wind Turbine Blade

open access: yesMaterials, 2022
When designing a wind turbine, the main objective is to generate maximum effective power with the lowest possible production costs. The power of a wind turbine depends primarily on the aerodynamic properties of its blades. Moreover, the cost of making a blade for a wind turbine, and therefore also for the entire wind turbine, depends on the materials ...

Exploring the Influence of Wind Turbine\u27s Blades on Its Output and Efficiency [PDF]

open access: yes, 2019
Wind turbines are machines that convert wind energy into electricity. The efficiency of this conversion is measured by comparing the incoming wind\u27s speed and the output power.

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe 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.

The Use of Renewable Energy in Prominent City Buildings: A Diffusion Study on Top European Football Organizations

open access: yesBusiness 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 ...

Measuring Corporate Alignment With the Circular Economy: a Text‐Based Circularity Index From Mandatory Non‐Financial Disclosures

open access: yesBusiness 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 ...
