Specks or unmelts are more likely in off-spec or post-industrial recycled material
. If you find contaminants in your raw material
, confer with your supplier about remedies and increase your QC testing of incoming material
These devices also allow the loading of multiple sheets of rubber at a time, permitting a high degree of batch blending prior to mixing the final stage, again allowing a reduction in possible batch-to-batch variation caused by the masterbatch material
. A warming room can also be a very useful addition, not only for natural rubbers, since this can also aid with mastication, mix time, consumed energy and batch consistency, because the viscosity of the polymer can be reduced and the temperature of other materials
Before the Sarbanes-Oxley Act, when an audit partner walked into the controller's office and said, "We found a material
error during our review of the company's Form 10-Q or 10-K report," the controller was, of course, appalled an error had occurred.
The traditional way is to use either a rubber-tired or crawler-mounted material
handler driven by a diesel engine.
* Learn to characterize self-assembled natural and synthetic material
Sotzing says the materials
can be designed so that a change in the resistance of the polymer lines would cause the material
to swell and emit light of a particular color.
So he chose travertine, that immemorial material
, still quarried near Rome.
In most practices, impressions for study models or for whitening trays are taken with disposable or reusable perforated trays and alginate impression material
. Reusable metal trays come in a variety of sizes, and several trays may need to be tried in the patient's mouth to determine the correct size.
Whether one speaks of Bernstein Brothers or later collaborators like Peter Ballantine or Rob Weiner, Judd's works resulted from an intersection between the initial concept and an extensive knowledge and experience of working with particular materials
. An incredible amount of labor and care was taken to create Judd's works, from handling materials
as they came into the shop to assembly, polishing, and shipping.
, commonly used as physical evidence in both criminal and civil cases, can play an important role in forensic science.
In broad terms, there are four variables that determine how long archival material
will last--the type of media used (type of paper, CD, etc.), the quality of original, the use, and how the material
"There's tremendous potential for recovered wallboard to be recycled into new product, but, unfortunately, the raw material
is still dirt cheap," Turley says.
Even though these primary sources are the raw material
of new knowledge, and through the published work of scholars feed into the bloodstream of learning and popular culture, they do not command the attention of library administrators in the same way that heavily used serials or current monographs do.
Subsequent operations must completely remove the damaged material
It is believed that some of this material
is an aerosol and some of it is a mist, either of which can fit this definition.
