Hermaphroditism, associated with territoriality and dominance behavior, is common in the marine environment. While male sex-specific coloration patterns have been documented in groupers, particularly during the spawning season, few data regarding social structure and the context for these color displays are available. In the present study, we define the social structure and male typical behavio...

Under the influence of continuous external factors (rainfall, earthquakes, construction, etc.), slope rock masses in a stable state can gradually transition to unstable rock, which then collapse. A safety factor identify occurrence failure but cannot rock; thus, it realise quantitative identification latter. In this study, cohesive (CSF) and relatively objective analysis method are proposed eff...

Coal rock is rarely used as the foundation bearing strata. For buildings located on coal rock, it a reasonable and feasible way to obtain vertical characteristics of through field tests. Three plate load tests two bi-directional were carried out, design parameters capacity shallow deep obtained, respectively. The test results show that pressure–settlement curve steep-drop-type, deformation modu...

Uniaxial compressive strength (UCS) is one of the most significant factors on the stability of underground excavation projects. Most of the time, this factor can be obtained by exploratory boreholes evaluation. Due to the large distance between exploratory boreholes in the majority of geotechnical projects, the application of geostatistical methods has increased as an estimator of rock mass pro...

This paper is based on the open pit to underground mining practice of Daye Iron Mine. The influence mechanism between high-steep slope and non-pillar sublevel caving method is studied by using physical model test. Firstly, engineering geological properties of the choosing typical research section is analysed and generalized. Secondly, the system of open pit to underground mining is developing a...

BACKGROUND This study evaluated the utility of the Alcohol Use Disorders Identification Test Alcohol Consumption Questions (AUDIT-C) in screening at-risk drinking and alcohol use disorders among Korean college students. METHODS For the 387 students who visited Chungnam National University student health center, drinking state and alcohol use disorders were assessed through diagnostic intervie...
