Bed load sediment transport, in which wind or water flowing over a bed of sediment causes grains to roll or hop along the bed, is a critically important mechanism in contexts ranging from river restoration1 to planetary exploration2. Despite its widespre

However, they also conclude that their study underlines the statement that shear cells are less suitable for free-flowing materials. To be able to ultimately decide whether shear testing is an adequate method for characterizing powders for AM, a comprehensive study has to be performed. In recent ...
2. Material and methods 2.1. Experimental setup Fig. 1 presents the three-stage ENR-BP used in the present study. The process is comprised of three zones of moving bed biological reactors (MBBR) connected in a series: anaerobic (Z-1), anoxic (Z-2), and aerobic (Z-3). The total rea...
In the present study, the application of SLC elements in combination with proper smaller rock sizes as a new countermeasure material against the scour at the downstream of SJS is experimentally investigated. The SLC elements have been widely used as port breakwaters and for erosion control in river...
Alternative net use in this study involved repurposing rather than misuse. Repurposing was not detrimental to malaria prevention efforts in these communities. Standardized measurement of alternative net use should be used to better understand the practice and its potential impact on the success of malari...
A panel bed fitted for puffback cleaning is arranged so that a precoat surface layer deposit of a fine granular or fibrous medium, of particle size finer than the granular material charged to the pane
The objective of this study is to investigate the red bed slope stability considering the rainfall patterns and anisotropic permeability of crack based on a real engineering slope located in the red bed area in Yunnan Province. The measured rainfall data collected from the meteorological data station...
In this context, this study presents a discontinuum modeling strategy, based on the discrete element method, developed to investigate the tensile fracture mechanism of masonry wallettes parallel to the bed joints considering the inherent variation in the material properties. The applied numerical ...
To our knowledge, this is the first study to quantify the passage of bed bugs through commonly used LLINs in two distinct contexts, host-seeking by unfed bed bugs and shelter-seeking by fed bed bugs. Using innovative behavioral assays, we were able to show that the presence of commercial...
