We are describing a method to subject adherent cells to laminar flow shear stress in a sterile continuous flow circuit. The cells' adhesion, morphology can be studied through the transparent chamber, samples obtained from the circuit for metabolite analysis and cells harvested after shear exposure for future experiments or culture.

Beech bark disease is initiated by feeding activities of the beech scale insect that create fungal entry points in the bark. Trees that are resistant to the scale insect are also disease resistant. Here we present the protocol we have developed to screen individual beech trees for beech scale resistance.

Source: Jaideep S. Talwalkar, MD, Internal Medicine and Pediatrics, Yale School of Medicine, New Haven, CT Simply stated, percussion refers to the striking of one object against another to produce sound. In the early 1700s, an Austrian inn-keeper's son, named Leopold Auenbrugger, discovered that he could take inventory by tapping his father's beer barrels with his fingers. Years later, while practicing medicine in Vienna, he applied this technique to his patients and published the first...

Dissipative Microgravimetry Technique to Study Protein-Lipid Bilayer Interaction
0 Views •
2025
This video demonstrates a dissipative microgravimetry technique to investigate the binding of proteins to lipid bilayers. Small unilamellar vesicles are added to coat the surface of the quartz sensor of a microbalance. Utilizing the calcium ion-dependent binding of the target phospholipid-binding protein to the bilayer, changes in the oscillation frequency of the sensor and the dissipation of the oscillation are monitored to determine the nature of the protein-lipid bilayer binding.
FAQs
Damping features dissipate mechanical energy rather than allowing it to remain as repeated mold motion. Compliant interfaces, dampers, or energy-absorbing materials absorb part of the vibration generated during placement or compaction. This reduces oscillation in the formwork, helping the mold maintain its intended geometry while the material is being processed or cured.
These components provide locations where mechanical energy can be absorbed or dissipated. Instead of transferring all vibration directly through the mold, the compliant or absorbing element limits the intensity of movement. That behavior is important because uncontrolled motion can affect dimensional accuracy and surface finish, particularly during concrete placement and mechanical compaction.
Performance is especially relevant under mechanical vibration, fluid pressure, or disturbance from nearby equipment. Each condition can promote movement while material is placed, compacted, or cured. The damping approach therefore matters most when the form must resist dynamic loading and preserve its geometry despite forces that could otherwise produce oscillation or displacement.
The formwork retains the material while its damping features limit movement through the main processing stages. During placement and compaction, the system reduces oscillation caused by mechanical activity; during curing, it continues to support geometric stability. This sequence helps maintain the mold shape throughout fabrication rather than only at the initial placement stage.
For concrete fabrication, limiting mold motion can support more consistent placement, improved dimensional accuracy, and a better surface finish. It can also reduce defects associated with movement of the mold during processing. These outcomes make damping relevant when the quality of the finished form depends on maintaining stable geometry under dynamic conditions.
They are particularly useful where vibration, fluid pressure, or nearby equipment may disturb a temporary or reusable mold. Such conditions can arise during fabrication activities that include placement, compaction, or curing. By controlling movement in these settings, the approach supports safer and more reliable fabrication while addressing defects linked to mold instability.
