In the 25 TKR patients an European standard series of 30 contact allergens including a Co, a Cr, and a Ni preparation (Hermal, Reinbek, Germany) supplemented by a metal allergen series (Brial Allergen GmbH, Greven, Germany) as well as a bone cement component series in case of cemented arthroplasty was tested on the patients' back.
Lithomex is significantly stronger than Conserv, due in part to its 20% cement component.
Carbonate is the most important cement component in the Xing'anling sandstones.
The paper describes a study undertaken to examine the use of high levels of low-lime fly ash (high volume FA) as a cement component in concrete, beyond the 30% level commonly adopted.
The material characteristics indicate potential for various applications: in small dosages as raw feed in Portland cement production, as fine and filler aggregates, or in ground form as cement component, with manageable effects on performance.
The results also shown the C3A as a cement component having a positive response to the conditions of the combination of very low water:solid ratio and pressure compaction.
We hypothesized that the limiting factor of the interface would be the cement component, and that there would be little difference between the 2 study groups.
The cement component of the scale cover is a proteinaceous liquid released from the anal opening during scale formation, which is mixed with the filaments by movements of the insect's pygidium.
Mercury, which can harm childhood development of the brain and is linked to asthma, heart attacks and premature deaths, is released when cement components are heated in a kiln, according to agency documents.
Table 1 gives a summary of the functionality provided by the cement components.
