Properties of municipal solid waste incineration ashes with respect to their separation temperature.

Fly ashes generated by power and heating plants are commonly used in the production of building materials in some countries, mainly as partial replacement of cement or aggregates in concrete. The ashes from municipal solid waste incinerators can be applied in a similar way. However, their chemical and mineralogical composition, granulometry and toxic constituents have to be taken into account.

[Comparison of four methods for efficient isolation of Aspergillus DNA from peripheral blood samples].

Aim Of The Study: The main goal of this study was to find the best method for Aspergillus DNA isolation from peripheral blood samples. The method should be very effective but not expensive or time consuming to be suitable for routine diagnostics use.

Material And Methods: We compared four different methods for Aspergillus DNA isolation - one method with enzymatic lysis of the fungal cell wall and three methods that combine chemical and mechanical lysis (using high speed cell disruption with glass beads).
