Assessing the Impact of Nitrogen Trade‐Off Between Coffee Tree Productivity and Bean Sensory Attributes to Produce Australian ‘Specialty Coffee’

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 2, June 2026.
Effective nitrogen management is essential for sustainable coffee production and enhanced yield. This study evaluated the effects of five nitrogen application rates (per annum; N1: 120 kg/ha, N2: 240 kg/ha, N3: 360 kg/ha, N4: 480 kg/ha, N5: 600 kg/ha) applied in equally distributed monthly rates over 2 years, from flowering to harvest, on Coffea ...

Anchorage System Contribution to Post‐Tensioned Bridge Collapse

Engineering Reports, Volume 8, Issue 5, May 2026.
This paper presents an experimental investigation of a 1960s precast post‐tensioned girder bridge in Trstena, Slovakia, revealing severe corrosion and anchorage degradation that ultimately led to its collapse. The findings highlight critical vulnerabilities in obsolete anchorage systems and emphasize the need for proactive assessment and maintenance of

Modeling the response of UHPC shear‐critical beams: Integrating nonlinear finite element analysis and artificial neural network

Structural Concrete, Volume 27, Issue 2, Page 1364-1382, April 2026.
Abstract An analytical framework suited for the analysis of shear‐critical ultra‐high performance concrete (UHPC) members is presented. The numerical methodology utilizes a nonlinear finite element analysis formulation integrated with an artificial neural network (ANN) that characterizes the UHPC tension response based on its mix design. In addition, a

Feasibility Analysis of Synchronous Paving of Epoxy Resin Tack Coat and Mixture in Steel Bridge Deck Pavement

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Aiming at the prominent engineering drawbacks of epoxy resin bonding layers on steel bridge decks—namely the narrow construction window, excessive curing triggered by paving delays due to rainfall, and the subsequent interlayer bonding failure as well as schedule and economic losses—this paper innovatively proposes a synchronous paving technology ...
