In synthetic materials (such as polymers, metals or ceramics), flaws typically lead to catastrophic failure at relatively small strains (often less than a few percent), preventing a material from undergoing very large deformation, reliably.
Remaining Comet 1s and 1As were either scrapped or modified with oval window rip-stop doublers (a thick, structurally strong ring of material that prevents a crack from spreading further).
This finding shows that hemilaminectomy alone is not a surgical procedure that prevents a recurrence of extruded disc material from causing clinically significant spinal cord compression.
The in sequence exposure of oxygen and acetylene plasma on POM substrate prevents a sufficient intermixing between both materials.
In order to prevent a photodegradation of the material, which preferentially occurs at wavelengths of λ ≤254 nm, UV-irradiation was carried out under nitrogen atmosphere at wavelengths higher than 300 nm.
However, it can also be construed as a bill that prevents sexual material of all kinds from receiving ready distribution online, a fact that is giving some big content providers pause.
It's no masterpiece, but there's just about enough material to prevent a table from wobbling.
The grain size should be over 8 mm and compacted very well to prevent a possible removal of the material.
Berkeley students seem naturally critical, especially the graduate students, and early on I noticed that for some students their overly critical attitude seemed to prevent a deeper engagement with the material.
This was not as easy to create as it may sound, since in order to prevent a rash, a diaper's material must "wick" the moisture away from the baby's skin, rather than absorbing the moisture and retaining it inertly.
As teams of Japanese engineers scramble to prevent a disastrous release of radioactive material from the Fukushima nuclear plant, scientists are already preparing for a challenge that may unfold over several years: Tracking the spread of radioactive material beyond the reactors and monitoring the radiation it emits in the environment.
