Conventional hydraulic fracturing is not effective in target oil development zones with available wellbores located in the azimuth of the non-maximum horizontal in-situ stress. To some extent, we think that the radial hydraulic jet drilling has the functi... see more

The shrinkage of swelling rock boreholes in coalmines is a complex problem affected by multiple fields coupling, such as humidity field and stress field. By establishing the equilibrium equation of swelling rock boreholes in coalmines, considering the exp... see more

Chlorinated solvents are among the most widespread pollutants of groundwater. As DNAPLs (dense nonaqueous phase liquids), they can move rapidly and in complex patterns through fractures to reach and contaminate large volumes of aquifer, and then dissolve ... see more

One of the hydrological responses in a watershed is influenced by the shape of the watershed (DAS). Lempake watershed with an area of 194.50 km2 has a radial shape. So it is necessary to develop a model to determine the factors that influence the watershe... see more

Communities in Kalimantan areas need wood for building materials. They use Tumeh wood (Combretocarpus rotundatus Dans) because of its found abundantly in forest area in Central Kalimantan. Tumeh is a kind of pioneer. Wood parts affect the quality of wood.... see more

The paper presents an algorithm for constructing the family of the atomic radial basis functions of three independent variables  generated by Helmholtz-type operator, which may be used as basis functions for the implementation of meshless methods for... see more

When determining the mechanical properties of ring specimens, a feature of a uniaxial (standard) loading scheme is that the method of applying a load to a specimen is somewhat remote from that to which the pipe walls can be subject in real operating condi... see more
