Surfactants are multipurpose products found in most sectors of contemporary industry. Their large-scale manufacturing has been mainly carried out using traditional chemical processes. Some of the chemical species involved in their production are considered hazardous and some industrial processes...

Generally, official statistical reports provide information on the pollution extent over a region using the average records from all the observation sites. In the outliers' presence, the average is not a good choice. Therefore, in this article, we propose two alternatives for replacing the average...

Crop harvesting has been pointed as the main source of soil compaction in sugarcane fields because of the high stresses induced by the machinery; however, little is known about the magnitude of the stress transmitted to the soil by these machines in the compaction process. The aim of this study was ...

A detailed knowledge of the stable isotope signature of precipitation is the basis of investigations in a variety of scientific fields and applications. To obtain robust and reliable results, the representativity of the currently operating (at least, as of 2018) precipitation stable isotope...

The benefits of the Taguchi method have been demonstrated in diverse fields. However, its applicability to soil erosion experiments at the slope scale under various conditions remains unclear. Using 6 published datasets that included the dependent variables of erosion rate (D), runoff rate (R),...

The shear strength originating from the root system of vegetation that mechanically stabilizes a soil slope against shallow landslides is called "root cohesion". The magnitude of the root cohesion depends on the root architecture and root tensile strength, which are well known to have high...
