American Journal of Agricultural Economics, EarlyView.Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT To alleviate the impact of the instability of renewable energy power generation on the power grid, coal‐fired power plants (CFPPs) have to undertake peak shaving tasks, which puts forward high requirements for the flexibility of CFPPs. To enhance the flexibility of CFPPs to consume more renewable energy, this paper innovatively proposes a ...

Experimental Investigation of Microbubble Evolution in the Liquivac Multiphase Flow Pump
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This paper aims to experimentally investigate the mechanisms of microbubble characteristics evolution within an axial pump. The findings will aid in assessing the pump performance by identifying the range of bubble sizes and comparing them with the threshold size (< 300 μm). This study also provides evidence supporting the use of such pumps as

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.
