Recycled household ceramic waste in eco-efficient cement: a case study
Ding, Yining; Dong, Huiwen; Cao, Mingli; Pacheco-Torgal, F.; Azevedo, CeciliaThe ceramic wastes can cause strong damage to the environment. In this article, the experimental study was concentrated on the pozzolanic activity of household ceramic waste and clay bricks waste. The possibility of the partial replacement of Portland cement blended with ceramic waste powder without further heating treatment in different ratios was analyzed. The ceramic waste powder was mixed in samples in vari...
Thymic function as a predictor of immune recovery in chronically HIV-infected p...
Rb-Silva, Rita; Nobrega, Claudia; Azevedo, Cecilia; Athayde, Emilia; Canto-Gomes, João; Ferreira, Ivo; Cheynier, Rémi; Yates, Andrew J.; Horta, AnaPoor immunological responders (PIR) are HIV-infected patients with virologic suppression upon antiretroviral therapy (ART) but persistently low CD4+ T cell counts. Early identification of PIR is important given their higher morbimortality compared to adequate immune responders (AIR). In this study, 33 patients severely lymphopenic at ART onset, were followed for at least 36 months, and classified as PIR or AIR ...
