    Abstract: Slopes are not stable due to the variations of slope gradient combined with the driving forces including the groundwater action, producing shear stresses in the slopes, which are contradicted by the soil shear strength. The slopes instability may cause the displacement of the mass of soil downstream recognised as landslide. Consequently, landslides... Show More

    Abstract: Humans, animals, and plants need copper for growth and development, but it can be an irritant to humans. The daily maximum limit of copper for humans is 10-12 µg day-1 and excess concentrations of copper can cause nausea, diarrhea, and anorexia. In plants, excess copper concentrations cause chlorosis, stunted growth, and denaturing of macromolecule... Show More

    Abstract: The quality of soil is influenced by natural activities: geological formations of an area and volume of water (rain), as well as anthropogenic events such as land use patterns. The patterns correlate with the trace metals load in an area. This study, thus, seeks to evaluate of the potentially toxic metals loads in both top and sub soils based on la... Show More
