Abstract:
... Bladelets and microliths have been recognized as key parts of the late prehistoric cultural dynamics on a global scale and recently discussed in relation to the range expansion of Homo sapiens in the late Pleistocene. This paper focuses on some of the current issues on bladelet technology in the Levant, including 1) the occurrences of bladelets in the Late Middle Paleolithic (LMP) and Initial Uppe ...

Abstract:
... Recently, several studies have presented quantitative data of lithic assemblages from Islands Southeast Asia (ISEA), based on technological and morphological analyses. While this has led to a better overall understanding of the nature of these assemblages, there is still lack of clarity about the relationship between manufacturing technology and usage. Accordingly, this study collected detailed da ...

Abstract:
... Beneficial to the environment but complex in nature, closed-loop supply chain (CLSC) has been understandably a topic of studies for a lot of researchers. However, most of the literature focuses on the homogeneity of CLSC products and on the dyadic structure of the CLSC mostly involving single manufacturers, distributors, or retailers. Very seldom do we find studies conducted in the analysis of the ...

The prepared ZnOHF had a unique flower-like architecture self-assembled by nanorods with a diameter of 150 nm and length of 2–3 μm. The sensing performance toward NO₂ detection indicated that the prepared ZnOHF exhibited high response (82.71), short response/recovery time (13 s/35 s) to 10 ppm of NO₂, ...

Abstract:
... A major impact of the Last Glacial Maximum (LGM) on the East-Central European Upper Paleolithic (UP) demographic and cultural adaptation is now largely acknowledged. Archaeologically, the basic trend leading to a fragmentation of the Gravettian technocomplex and the emergence of increasingly regionally-focused paleo-cultural units is also generally agreed upon. Higher-resolution regional syntheses ...
