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.

Characterization and Selection of Contractile Actuators for Soft Robotics Operating in the Quasistatic Regime

Advanced Intelligent Systems, EarlyView.
We developed methods to characterize soft contractile actuators using force–displacement measurements in the passive state and the total force in the active state and define the operational range of thermal, electrothermal, and pneumatic muscles. A graphical method enables the selection of an actuator based on the required mechanical force–displacement

Roux‐en‐Y gastrojejunostomy and jejunojejunostomy for pyloric obstruction bypass in a horse and a foal

Equine Veterinary Journal, EarlyView.
Abstract Background Gastric outflow obstruction in horses is a rare but challenging condition, often resulting from either congenital anomalies or acquired lesions such as chronic ulceration or pyloric polyps. Conventional surgical bypass procedures, including gastrojejunostomy (GJ) or gastroduodenostomy and less commonly duodenojejunostomy, can ...
