In this paper, the effects of different aluminum to silicon ratios in silicate chains of calcium silicate hydrates (C-S-H) are evaluated on the diffusion coefficient of chloride ions by molecular dynamics method. Tobermorite is a crystalline phase that is used for studying C-S-H properties in nano scale, because of its analogous chemical composition to C-S-H. Aluminum incorporation in C-S-H and...

objective(s): htlvi-1 is the first human retrovirus with limited endemic regions in the world. the epidemiological studies have shown that the genetic background and immune response to the virus have a significant role in htlv-i-associated diseases.  among the genes are involved in htlv-i infection, the role of human leukocytes antigen (hla) have been studied in different population. in the pre...
