Delineation of a PFOA Plume and Assessment of Data Gaps in its Conceptual Model Using PlumeSeeker™.

An accurate conceptual site model (CSM) and plume-delineation at contamination sites are pre-requisites for successful remediation and for satisfying regulators and stakeholders. PlumeSeeker™ is well-suited for assessing data gaps in CSMs by using available site data and for identifying the optimal number and locations of sampling locations to delineate contaminant plumes. It is an enhancement of a university research code for plume delineation using geostatistical and stochastic modeling integrated with the groundwater modeling software MODFLOW-SURFACT™.

Food and social complexity at Çayönü Tepesi, southeastern Anatolia: Stable isotope evidence of differentiation in diet according to burial practice and sex in the early Neolithic.

The identification of early social complexity and differentiation in early village societies has been approached in the past most notably through the evaluation of rituals and architectural layouts. Such studies could be complemented by an approach that provides data about everyday behaviours of individuals. We took 540 human and animal bone samples for stable carbon and nitrogen isotope analysis from the Neolithic site of Çayönü Tepesi in southeastern Anatolia.

Auditory exostoses among the prepottery neolithic inhabitants of Çayönü and Aşıklı, Anatolia; its relation to aquatic activities.

Most researchers argue that there is general agreement on the role of environmental and behavioral factors on the onset of the auditory exostoses. Accordingly, it can be considered an aquatic activity marker in bioarchaeological studies. In this paper, the prevalence of external auditory exostoses was examined between two prepottery Neolithic communities from Aşıklı Hüyük and Çayönü Tepesi in Anatolia.
