Compactação de solos cultivados com cana-de-açúcar: I -modelagem e quantificação da compactação adicional após as operações de colheita Compaction of soils cultivated with sugarcane: I - modeling and quantification of the additional soil compaction after harvest operations

Engenharia Agrícola, 2010
A colheita mecanizada da cana-de-açúcar, quando realizada em épocas da safra em que o solo se encontra com conteúdos inadequados de água, tem sido responsável pela compactação do solo e a redução da produtividade nos ciclos posteriores da cultura.

Extended Kelvin–Voigt Model for Simulating Thermally Accelerated Creep in Fine‐Grained Soils

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 4, Page 1843-1854, March 2026.
ABSTRACT The subsurface undergoes temperature variations in many situations due to anthropogenic and natural causes, which strongly influence the long‐term behavior of soils. These phenomena can involve temperature anomalies in the ground across distances of a few meters, as in the case of nuclear waste repositories, to distances encompassing entire ...

A pilot study of chemoimmunotherapy in the postconsolidation setting for high‐risk neuroblastoma (ANBL19P1): A report from the Children’s Oncology Group

Cancer, Volume 132, Issue 2, 15 January 2026.
Abstract Background Survival for patients with high‐risk neuroblastoma remains poor despite current‐era multimodality treatment that includes postconsolidation GD2‐directed immunotherapy. Given the promising responses in patients who receive dinutuximab‐based chemoimmunotherapy in the relapsed setting, the Children’s Oncology Group ANBL19P1 study ...

Research on Settlement Prediction and Control of Lock Floor Concrete Pouring Construction

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
As the core structure of inland waterway hubs, lock engineering’s structural safety directly affects navigation efficiency and life cycle benefits. With the advancement of “quality engineering,” construction accuracy requirements have evolved from traditional strength control to three‐dimensional spatial precision, particularly for floor slab elevation,
