Exhaustion other profiles

Ren stndied the exhaustion profiles and concluded both theoretically and experimentally that the quadratic exhaustion profile is more likely to result in better levelness than any other profile. The control of the exhaustion of a dyeing process to achieve the various profiles will be discussed in Chapter 7. 

The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for the hazardous substance described therein. Each peer-reviewed profile identifies and reviews the key literature that describes a hazardous substance s toxicologic properties. Other pertinent literature is also presented, but is described in less detail than the key studies. The profile is not intended to be an exhaustive document however, more comprehensive sources of specialty information are referenced. 

The replacement of timber products by nonrenewable materials is an unfortunate development, since it has been repeatedly shown that the use of timber does have associated environmental benefits compared with the use of nonrenewables (e.g. Marcea and Lau, 1992 Hillier and Murphy, 2000 Bowyer etal., 2003 Lippke etal., 2004). Timber has a lower embodied energy content (and hence a more favourable carbon emission profile) compared to most other building materials and can provide other benefits, such as improved thermal properties. It and the products made from it (in common with other renewable materials) can be used as a repository for atmospheric carbon dioxide. Wood is derived from a renewable resource, albeit potentially an exhaustible one unless it is managed correctly. Disposal of wood can be readily achieved with little environmental impact (subject to how the wood has been treated prior to disposal). 

Other pertinent literature is also presented, but described in less detail than the key studies. The profile is not intended to be an exhaustive document however, more comprehensive sources of specialty information are referenced.
