Even when the material is serious, the approach seems lighthearted, and the selections are interspersed with the singing of such happy period tunes as "In My Merry Oldsmobile". An old labor song is much more to the point.
The randomness of strength and deformation of concrete material is serious and should be considered both in theoretical analyses such as Finite Element Methods and engineering practice, specially for those structural members with a uniform stress field, where stresses or strains are approximately the same under loading.
Few of the more modern industrial materials are of serious concern to the home model engineer with a light lathe, and virtually all turning will be done using either carbon steel, high speed steel or tungsten carbide tipped tooling.
There are serious material and domestic political reasons for opposing it – the loss of jobs, higher-priced imports, weakened safeguards at work and elsewhere.
BP is ramping up its gas activities.There are two-and-a-half material sources if you are serious about reducing carbon emissions.
Even under fluoroscopic guidance, inadvertent penetration of the floor of the spinal canal with subsequent leakage of material into the dural space are serious complications and major limitations of this model [ 22].
Splashing mechanisms such as bubble boiling and various liquid magnetohydrodynamic (MHD) instabilities and brittle destruction mechanisms of nonmelting materials can be serious erosion mechanisms and are being studied in detail.
Mr. Elkins and his fearless and personable dancers -- who also include Fritha Pengelly, Brian Caggiano, Rebecca Chisman, Charemaine Seet and Bernard Brown -- are serious about the material rather than themselves, an important and rare distinction.
Desensitization and "numbing" are serious reactions to witnessing traumatic material.
"The department's willingness to provide these materials is a serious, good-faith effort to bring this matter to an amicable resolution," Mr. Holder said.
