Dyrektywy Unii Europejskiej dotyczące zmniejszenia emisji tlenków azotu (NOx) do atmosfery przez przemysł energetyczny wymuszają stosowanie nowych technologii odazotowania spalin. Taki proces może negatywnie wpływać na jakość ubocznych produktów spalania (UPS) [1–2]. Dlatego podjęto badania mające określić wpływ zawartości amoniaku na właściwości popiołów lotnych. Objęto nimi popioły lotne krzemionkowe...
This paper presents the results of research undertaken to determine the impact of the aggressive environment of acid corrosion on the durability of cement mortars with the participation of fluidized beds boiler fly ashes and conventional fly ashes used separately and in the form of mixtures. The beneficial effect of fluidized beds boiler fly ashes on the physical properties of cement mortars has been...
Vernalization-induced flowering is an effect of the epigenetic regulation of gene expression through DNA methylation and histone modifications. Vernalizationmediated silencing of a floral repressor through histone modifications was shown in Arabidopsis thaliana. However, for Brassica napus L., the mechanism underlying vernalization is unclear, and the roles of DNA methylation and histone modifications...
