The internal crest anatomy of Lambeosaurini (Hadrosauridae: Lambeosaurinae)

The Anatomical Record, EarlyView.
Abstract The supracranial crests of lambeosaurine hadrosaurids have long been a focus of study due primarily to their extreme morphology. The external anatomy of lambeosaurine crests is understood to be highly variable between species, but variation in their internal anatomy is less well understood.

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

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

Investment, Efficiency, and Credit Rationing: Evidence from Hungarian Panel Data [PDF]

Relying upon a rich and unique panel of Hungarian firms over 7 years, from 1992 up to 1998, this paper estimates simultaneously TFP, Total Factor Productivity, identified as efficiency, and the parameters of a model where investment depends upon internal

Comparison of examination performance and test anxiety during bell‐paced and self‐paced gross anatomy laboratory examinations

Anatomical Sciences Education, EarlyView.
Abstract Pacing during anatomy laboratory examinations may influence both student performance and test anxiety. This study compared bell‐paced (BP) and self‐paced (SP) timing structures to assess their impact on students' test performance, test anxiety, and pacing preferences.

Effects of Credit Constraint on Productivity and Rural Household Income in China [PDF]

Chinese rural household has been always facing credit constraints. Few institutions lend loans to farmers because of financial risks. Farmers have to use usury or other informal sources to meet the financial needs for production.

A sustainable business ecosystem: a case study demonstrating biochar's potential

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The need for renewable, climate‐friendly resources has become urgent as legislators worldwide have sought to find ways to cut emissions while ensuring resource security for consumers. The use of biochar could help to achieve these goals. This study examines the current state of commercial biochar production and the maturity of the related ...

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

Fiscal policy with credit constrained households [PDF]

This paper explores the effects of discretionary fiscal policy in a DSGE model that explicitly models housing investment and allows for credit constrained households along the lines of the financial accelerator literature.The presence of credit ...

Comparative field‐scale assessment of TLUD and Kon‐Tiki biochar systems: agronomic performance and net CO2e‐based techno‐economics

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Post‐harvest agricultural residues in Latin America are commonly underutilized, leading to greenhouse gas emissions and lost opportunities for bio‐based value creation. This study tests the hypothesis that decentralized, farmer‐scale pyrolysis technologies can deliver comparable agronomic benefits while exhibiting distinct techno‐economic and ...

Emissions trading without a quantity constraint. [PDF]

This paper examines the differences between standard “cap-and-trade” emissions trading plans and “credit” plans in which individual agents create credits by reducing emissions below a firmspecific baseline.
