Expansive and collapsible soils are some of the most widely distributed and costly of geologic hazards. These soils are subject to changes in volume and settlement in response to wetting and drying, often resulting in severe damage to structures. Collapsing soils are generally characterized by sudden and large volume decrease at constant stress when inundated with water. A geotechnical engineer...

The present study aims to obtain p-y curves (Winkler spring properties for lateral pile-soil interaction) liquefied soil from 12 comprehensive centrifuge test cases where pile groups were embedded in liquefiable soil. curve fully is back-calculated the dynamic data using a numerical procedure recorded response and strain records instrumented pile. obtained two ground conditions: (a) spreading o...

The discrete element method constitutes a general class of modeling techniques to simulate the microscopic behavior (i.e., at the particle scale) of granular/soil materials. We present a contact dynamics method, accounting for the cohesive nature of fine powders and soils. A modification of the model adjusted to capture the essential physical processes underlying the dynamics of generation and ...

The digging work parts of modern potato harvesters, when working on loamy soils with low humidity, do not meet the agrotechnical requirements. Modern machines should perform pruning, lifting, and moving bed layer to separating organs without unloading collapsing least energy consumption, losses, damage tubers. authors proposed combined passive plowshares active augers. purpose study is substant...

Collapsing glomerulopathy is a devastating renal disease that primarily affects African Americans and associates with numerous etiologies, such as HIV and autoimmune disease. The presence of APOL1 risk alleles associates with HIV-associated collapsing glomerulopathy, but it is unknown whether these risk alleles also associate with systemic lupus erythematosus (SLE) -associated collapsing glomer...
