Impact of Ten Years Conservation Tillage in Organic Farming on Soil Physical Properties in a Loess Soil—Northern Hesse, Germany

Agriculture, 2023
In conservation agriculture, conservation tillage potentially influences the physical, chemical, and biological quality of the soil. Although the effects of conservation agriculture on the soil’s physical properties have been studied in conventional ...

Soil compaction and stress propagation after different wheeling intensities on a silt soil in South-East Norway

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2019
The objective of this study was to evaluate the effect of wheeling with two different wheel loads (1.7 and 2.8 Mg) and contrasting wheeling intensities (1x and 10x) on the bearing capacity of a Stagnosol derived from silty alluvial deposits.

Stump Ischemia Is a Possible Risk Factor for Late‐Onset Pancreatic Fistula After Distal Pancreatectomy

Journal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background This study was conducted to determine the clinical significance of pancreatic stump ischemia (PSI) in predicting late‐onset pancreatic fistula (LOPF) following stapled distal pancreatectomy (DP). Methods A total of 165 patients who underwent stapled DP between July 2018 and March 2024 were included.

Looking at Soil as It Is: Evolution of Microscopic Soil Characterization From Kubiëna to Artificial Intelligence

Journal of Plant Nutrition and Soil Science, EarlyView.
We provide a historic overview of microscopic soil structure characterization from its founding father, Walter Kubiëna, to several technical revolutions like automation, digitalization, and artificial intelligence. In addition to technical advancements, we explore how concepts and research questions have evolved in time.

Evaluation of prestress losses in concrete beams using destructive and non‐destructive methods

Structural Concrete, EarlyView.
Abstract Over the past few decades, prestressing techniques have become essential in the construction of key structures, infrastructure, and bridges. The serviceability and safety of prestressed concrete (PC) elements are closely tied to the effectiveness of the prestressing process.
