The Mobile Core: Perpetuating Tourism Leakage Through the Socioecological Fix in South Korea

Asia Pacific Viewpoint, EarlyView.
ABSTRACT By adopting the socioecological fix concept, this study aims to examine the spatial dynamics of tourism leakage. An ethnographic examination of an ecotourism project on Jeju Island, South Korea was conducted for 18 months from 2011 to 2013.

Modeling cave propagation in deep block caving by incorporating the fracture zone inferred from seismic tomography

Mining of Mineral Deposits
Purpose. This study aims to enhance the monitoring of cave propagation in block caving developments by integrating microseismic tomography for numerical modeling of rock mass evolution due to mining and displacement distribution. Methods. This study used the low-velocity zone identified by four-dimensional tomography as a fracturing or loosening

The Impact of the Strength of Roof Rocks on the Extent of the Zone with a High Risk of Spontaneous Coal Combustion for Fully Powered Longwalls Ventilated with the Y-Type System—A Case Study

, 2019
During the ventilation of longwalls in hard coal mines, part of the air stream migrates to the goaves with caving. These goaves constitute a space (void) filled with rocks following coal extraction. In the case where these goaves contain coal susceptible

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

Archaeometry, EarlyView.
ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

Mapping Palaeolithic Imprints: Spatial Analysis of Hand Stencils in El Castillo Cave (Spain) Through Geomatic Techniques

Archaeometry, EarlyView.
ABSTRACT We present the application of a new quantitative approach to space study in Palaeolithic cave art. Using GIS, we analysed the distribution and position of hand stencils in El Castillo cave to track the gestures and behaviours of Palaeolithic societies.

Failure characteristic and fracture evolution law of overburden of thick coal in fully mechanized sub-level caving mining

, 2017
In mining process, the height of water flowing fractured zone is important significance to prevent mine of water and gas, in order to further research the failure characteristic of the overlying strata.

Application of Multi‐Method Dating for Understanding the Gravettian North of Moravia, Central Europe

Archaeometry, EarlyView.
ABSTRACT This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka).

Modern Fire Safety Protocols in the Archeological Contexts: A New Tool for Studying the Health and Behavioral Effects of Fire Use in Semi‐Closed Spaces

Archaeometry, EarlyView.
ABSTRACT This study evaluates the application of computational fluid dynamics (CFD) simulations, integrated with controlled fire experiments, to investigate combustion processes in semi‐closed spaces. The framework enables systematic modeling of smoke dispersal, particulate transport, and hearth performance under variable morphologies and ventilation ...

INFLUENCE OF PRE-CAVING ZONES IN MOISTENED ROCKS ON VARIABLES OF HOLE BLASTING

, 1992
There was ascertained that for the rocks the radius of pre-caving zone, the indicator of structural caving degree and the degree of weakening of strength of containing rocks increase with the growth of moisture content.

Droughts and human impact in the ancient Uaymil region of the Maya lowlands inferred from a 2800‐year sedimentary archive at Lake Kaná, Mexico

Boreas, EarlyView.
The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...
