The technique also is a departure from conventional methods, which require that bacterial “biofilms” be damaged or destroyed in order to be tested.

The Portland Cement Association invites building industry representatives to submit nominations for its 2009 Sustainable Leadership Awards program, which was established last year to identify and honor government leaders who advance sustainable development through the use of concrete and cement-based products.
The awards program includes four categories:
- Leadership in sustainability policy
- Homes and residential building
- Non-residential building
The leadership category honors public officials who advance policies that promote the concept of sustainable development by advocating and promoting the use of concrete and cement-based products in their communities. The other categories honor public officials who use such products to achieve sustainable benefits for projects. Last year's winners were recognized for using new innovations and technologies such as pervious concrete, insulating concrete forms, full-depth reclamation, green alleys, and green roofs.
Buildings and activities must have occurred between Jan. 1, 2007, and Dec. 31, 2008, to be eligible. The deadline to submit final entries is May 29, 2009.
