The detrimental effects of sand storms on agriculture, human health, transportation network, and infrastructures pose serious threats in many countries worldwide. Hence, wind erosion is considered a global challenge. An environmental-friendly method to suppress employ microbially induced carbonate precipitation (MICP). However, the by-products ureolysis-based MICP, such as ammonia, are not favorable when produced large volumes. This study introduces two calcium formate-bacteria compositions...

Gas-condensate flow is a critical process in the near-well region where well production efficiency strongly affected by of condensate dropout. Pore-scale simulations have provided an understanding underlying processes such as snap-off and effect interplay between viscous capillary forces on gas-condensate its induced blockage within pore spaces. Among various modeling approaches used to explore these phenomena, pore-network modeling, due computational ability simulate relatively large sample...

The soil water retention curve (SWRC) is one of the most fundamental characteristics unsaturated soils. Because soils are subjected to a range natural processes and engineered treatments, thorough understanding needed how their properties change when exposed each separate treatment.
