The Appalachian region has experienced persistently higher poverty and lower earnings than the rest of the United States. We examine whether lower skill differentials or differences in the returns to those skills lie at the root of the persistent Appalachian wage gap. Using Census data, we decompose the Appalachian wage gap using both mean and full distribution methods. Our findings suggest tha...

BACKGROUND We established a rat model of chronic mountain sickness using acetyl-L-cysteine. Then we studied the effects and mechanisms of acetyl-L-cysteine (Da) in rats with chronic mountain sickness using nuclear magnetic resonance (H1-NMR) metabolomics methods. MATERIAL AND METHODS Using NMR spectroscopy combined with pattern recognition and orthogonal partial least squares discriminant ana...

Debris flow is a type of landslide that occurs mainly in mountain valley areas during heavy rainfall. Various types barriers have been installed South Korea to reduce the damage caused by debris flows. However, there no reasonable design standard when installing barrier, and an experimental study for performance evaluation insufficient. In this study, net-type barrier was evaluated analyzing ef...

In India, Kerala state is known to have relatively high lightning incidence. The nature of spatial and temporal distribution of past incidents, type of thunderclouds which cause lightning, the topography, proximity to a mountain range and sea point to the possibility of the mountain weather aiding in Cb formation. For investigating the role of mountain weather in convective Cb formation a field...

The karst mountain area in Buayan and Ayah subdistricts is a mountainous that stretches from North to South ends the coast region. In this area, many springs are found which source of clean water for residents. existence an indicator underground rivers flowing under also reinforced by presence interconnected caves river flows these caves. Analysis Karst study can be identified looking at type r...

When the Yellow River flows through Hetao Plain in Inner Mongolia, north China, it forms a mountain-river-desert system with Yin Mountains on one side and Hobq desert other side. In this system, dense growth of green grass is formed area fronting river mountains at back, however, opposite river, has an inherent trend to lost moisture, which might cause desertification. This study verifies theor...

Geomorphological field surveys and mapping have been carried out in a catchment of the Dolomites (eastern Italian Alps) as part research project aiming at assessment sediment availability for mass wasting mountain environments. The study area is Liera which was severely affected by high-intensity, regional-scale storm named ‘Vaia’ (27–30 October 2018), induced relevant morphological changes, ca...

We calibrate the k-ωSST turbulence model for free surface flows in channel or on slope using machine learning techniques. To model, an experiment is carried out inclined rectangular research chute. In experiment, pressure values flow are measured at different distances from bottom; after transforming data, velocity profile obtained. The calibrated based experimental data Nelder-Mead optimizatio...

Big Rock Candy Mountain is a prominent center of variegated altered volcanic rocks in west-central Utah. It consists of the eroded remnants of a hypogene alunite deposit that, at ~21 Ma, replaced intermediate-composition lava flows. The alunite formed in steam-heated conditions above the upwelling limb of a convection cell that was one of at least six spaced at 3to 4km intervals around the marg...
