Hemp Cultivation and Crop Diversification: Implications for Ecosystem Services in Kentucky
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT This study examines the ecosystem benefits of expanding hemp cultivation by assessing its impact on crop diversity. Using scenario‐based simulations and fixed‐effect panel regressions with county‐level data in Kentucky, we find that increased hemp acreage tends to enhance crop diversity, improving water quality and bird diversity.

The Anatomical Record, EarlyView.Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

The Anatomical Record, EarlyView.Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Study on the Reconstruction of Diversion Tunnel intoPressure Sudden Enlargement Release Tunnel
工程科学与技术, 2008 :High head ogee spillway is the most usual way for medium or low head hydropower stations to reconstruct the spillway tunnel. Due to the condition limitation of the topography and geology, some stations cannot employ in this way. A new way to reconstruct
