MECHANICAL BEHAVIOUR OF COMPOSITE GIRDERS SUBJECTED TO HOGGING MOMENT: EXPERIMENTAL STUDY
STRUCTURAL ENGINEERING / EARTHQUAKE ENGINEERING, 2011 In continuous composite steel-concrete structures, cracking of the concrete slab in the hogging moment region decreases the global stiffness of composite steel-concrete structures and reduces the effect of continuity, thus making the structural behaviour highly nonlinear even for low stress levels, so special consideration is necessary. An experimental

Livestock Tango: U.S. and Latin America Dance Together, but Who Will Lead?
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT This study examines the competitiveness between Latin American and U.S. livestock and meat sectors. We employ a computable general equilibrium modeling framework to evaluate two scenarios: coordinated improvements in Latin American productivity, transport efficiency, and market access (Scenario I), and the minimum productivity gains required ...

STATIC STRUCTURAL PERFORMANCE OF CONTINUOUS COMPOSITE SLAB STRENGTHENED BY CFRP LAMINATE IN THE HOGGING MOMENT REGION [PDF]
Journal of Engineering Science and Technology, 2018 The performance of continuous composite deck slab (CCS) strengthened with unidirectional carbon fibre-reinforced polymer (CFRP) laminate in the hogging region was investigated in this study, where the CFRP worked as an external reinforcement in the ...

Markets Mitigate Land‐Use Competition From Energy Crops and Increase Farm Revenues
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Meeting the US Sustainable Aviation Fuel Grand Challenge target of 35 billion gal annually by 2050 will require an estimated 380 million–700 million dry tons of agricultural biomass feedstock. This study evaluates the implications of large‐scale biomass production for land use, crop production, and market outcomes under mature market ...

Lateral-distortional buckling of continuous steel-concrete composite beam
Revista IBRACON de Estruturas e Materiais, 2018 In hogging bending moment regions of continuous composite beams the collapse by lateral-distortional buckling (LDB) can occur. The design against LDB according to ABNT NBR 8800:2008 begins with the determination of the elastic critical moment, which ...

Competition Policy and Agribusiness in the Biden Administration
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT The Biden Administration pursued a set of ambitious competition policy initiatives in agriculture and agribusiness, primarily aimed at livestock and poultry supply chains, farm inputs, and food retailing. The initiatives included expanded antitrust enforcement; new US Department of Agriculture (USDA) contract regulations requiring poultry ...

Advanced Intelligent Systems, EarlyView.This work proposes RT‐DETR‐DA, an enhanced real‐time detection framework for identifying distracted driving in complex, real‐world environments. The model introduces a dynamic sparse gating multiscale attention module and an attention‐guided dual‐path fusion module to strengthen multiscale perception and cross‐layer feature interaction.
