Experimental Stand Movable Module for Determining the Traction-Linked Properties of Wheel Engines and the Results of Laboratory Researches for Determining the Traction Force of Two-Wheel Tractors

open access: yesИнженерные технологии и системы, 2021
Introduction. Farmers make extensive use of two-wheel tractors equipped with traction and drive interchangeable units. Two-wheel tractors are required to move evenly with minimal slip of the drive wheels on the soil.

Measuring cellular traction forces on non-planar substrates

open access: yes, 2016
Animal cells use traction forces to sense the mechanics and geometry of their environment. Measuring these traction forces requires a workflow combining cell experiments, image processing and force reconstruction based on elasticity theory.

Wrinkle formations in axi-symmetrically stretched membranes [PDF]

open access: yes, 2004
International audienceWe study experimentally the main features of wrinkles that form in an initially stretched and flat elastic membrane when subjected to an axi-symmetric traction force at the center. The wavelength and amplitude of the wrinkle pattern

Traction forces during collective cell motion [PDF]

open access: yesHFSP Journal, 2009
Collective motion of cell cultures is a process of great interest, as it occurs during morphogenesis, wound healing, and tumor metastasis. During these processes cell cultures move due to the traction forces induced by the individual cells on the surrounding matrix. A recent study [Trepat, et al. (2009). Nat. Phys.

Traction forces of cancer cells [PDF]

open access: yesComputer Methods in Biomechanics and Biomedical Engineering, 2011
Cell motility of cancer cells is a fundamental problem, and requires precise correlation between cell adhesive and rheological properties. The migration of cancer cells is studied in two dimensions, as cells are seeded onto functionnalized polyacrylamide gels.

Microporous Microgel Assemblies Facilitating the Recruitment and Osteogenic Differentiation of Progenitor Cells for Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
There is a significant need for biomaterials with well‐defined stability and bioactivity to support tissue regeneration. In this study, we developed a tunable microgel platform that enables the decoupling of stiffness from porosity, thereby promoting bone regeneration.

Optimization of traction parameters for lumbar scoliosis

open access: yesBMC Musculoskeletal Disorders
Background Scoliosis is a high incidence disease that endangers the physical and mental health of adolescents. Traction therapy, as a conservative treatment plan, is helpful to improve the recovery speed of patients by studying the influence of different

Automatic Retraction and Full Cycle Operation for a Class of Airborne Wind Energy Generators [PDF]

open access: yes, 2014
Airborne wind energy systems aim to harvest the power of winds blowing at altitudes higher than what conventional wind turbines reach. They employ a tethered flying structure, usually a wing, and exploit the aerodynamic lift to produce electrical power ...

Switchable Supramolecular Adhesive by Tuning Interfacial Bonding and Modulus

open access: yesAdvanced Functional Materials, EarlyView.
The supramolecular adhesive (HyDiP) shows reversible adhesion and recyclability. In the dehydrated state, it is dense, stiff (E ≈445 MPa), transparent, and provides strong bonding with adhesion strengths up to 4.65 MPa. In the hydrated state, it becomes porous, soft (E ≈0.11 MPa), and detaches easily, enabling sustainable high‐strength applications ...
