The application of traditional anthropological methods is limited, especially if sex determination of children and fragmentary skeletal remains is detected. Sex typing genetic markers （SRY, amelogenin） were used for sex determination of children and undetermined fragmentary skeletal remains from the burial site Pohansko, south outer precincts （Czech Republic）. This is an approximately 1,200 year-old burial site （the Great Moravian period）, which was excavated during rescue excavations. After the genetic analysis, sex was determined in more than half of the investigated samples. The results of the genetic analysis were used for completion of demographic data of this archaeological site. The results of sex determination of several samples were independently verified by the Institute of Criminology in Prague （Czech Republic）, using the PowerPlex ESX 17 System （Promega）. This study showed the suitability of modem molecular genetic methods to skeletal anthropology and paleodemographic analyses.展开更多

The finite element method （FEM） is always used to predict the excavation behavior, whereas there are not many soil models available to consider this effect in analysis. This paper introduces a simple small strain soil model--hardening small-strain （HSS） in PLAXIS 8.5 and exhibits its application in excavation problems via studying the history of two cases. The analyses also use two familiar soil models： hardening-soil （HS） model and Mohr-Coulomb （MC） model. Results show that the HSS predicts more reasonable magnitudes and profiles of wall deflections and surface settlements than other models. It also indicates that the small strain effect relies on the strain level which is induced by excavation.展开更多
