Grounded language acquisition is an important issue, particularly to facilitate human-robot interactions in an intelligent and effective way. The evolutionary and developmental language acquisition are two innovative and important methodologies for the grounding of language in cognitive agents or robots, the aim of which is to address current limitations in robot design. This paper concentrates on these two main modelling methods with the grounding principle for the acquisition of linguistic ability in cognitive agents or robots. This review not only presents a survey of the methodologies and relevant computational cognitive agents or robotic models, but also highlights the advantages and progress of these approaches for the language grounding issue.

INTRODUCTION: Green tea is a medicinal beverage extracted from the plant Camellia sinensis. Antioxidants that exist naturally can be extracted as pure compounds from their parent materials for nutraceutical and medicinal applications. The present study aims to assess the antioxidant activity of Zinc oxide-titanium dioxide nano-composites (ZnO-TiO2 NCs) containing green tea extract.
MATERIALS AND METHODS: The antioxidant activity was tested by Hydrogen Peroxide [H2O2] assay, Fluorescence recovery after photo-bleaching [FRAP] assay and 2, 2-diphenyl-1- picrylhydrazyl[DPPH] assay. All tests have shown very good results for the ZnO-TiO2 NCs.
RESULTS: In this study, we present a straightforward, ecofriendly alternative for producing non-toxic zinc oxide and titanium oxide nano-composite material. This study could make a valuable contribution and create new opportunities in the market such as biological and pharmaceutical applications.
CONCLUSION: The in vitro tests concluded that the novel nanocomposite containing ZnO-TiO2 and green tea extract has good anti-oxidant properties and it is non-toxic to the biological systems.
