Such a Nexus can be defined as the very close links amongst the three elements (WEF) and how changes in one of them can have impacts on the other two (individually or both together) (Fig. 1). For countries worldwide, the WEF Nexus affects national water, energy, and food security and...
By measuring the radiance of a reflectance standard, the downwelling irradiance can be measured without the use of a cosine collector, assuming the standard is a Lambertian reflector. One radiometer can be used to make all the required light measurements in Equation (1). The benefit of using ...
The construction of this predictive regression model enables accurate predictions for this type of geological work under varying sets of mining parameters and conditions (mining height, protective coal pillar width, and block length), thus providing a form of on-site guidance that can, to an ...
The different geochemical ages eventually can be used to evaluate chemical differences in groundwater [20]. In our case, all samples are modern and thus vulnerable, however, no correlation between NO3− or other chemical components concentration with the age of the samples was seen. Thus, it...
Using mine tailings and waste rock as earthwork materials (e.g., water balance cover) can provide a sustainable and cost effective alternative to mitigate disposal and management challenges. Mine waste is categorized as a non-hazardous material based on Subtitle D of the Resource Conservation and ...
From this, it can be seen that the evolution of interface strength under shear is analogous to the damage process of metal materials. Assuming that the stress and strain at the interface conform to a specific statistical law based on the existing rock damage constitutive relationship, the damage...
By applying Kcr to both, an ideal reference crop and the monitored crop, the difference between these two can be translated into crop water stress. This approach is quite significant as it provides crop coefficients (Kc) for each stage of the crop rather than providing a static estimate of ...
Thus, the motor cavity can be used as parts of the flow path, which greatly reduces the pump volume. The traditional volute is substituted by the stay vane and guide section accordingly. The traditional one generates an axial inflow and a radial outflow, while an axial inflow and an axial...
