Power earth auger modification for waste extraction from pit latrines

Journal of Water, Sanitation and Hygiene for Development, 2013
The extraction auger was developed to meet the need for a low cost, effective method to empty pit latrines in difficult to access locations. The basic design consists of a motor that rotates an auger inside a pipe, lifting waste from a pit and depositing it into containers through a wye fitting at the top of the device.

Anorectal Dysfunction in Systemic Sclerosis: Clinical Phenotypes and Functional Patterns

Arthritis Care &Research, EarlyView.
Objective The aim of this study was to characterize specific physiologic defects in anorectal dysfunction in systemic sclerosis (SSc) using anorectal manometry (ARM), evaluate associations with gastrointestinal (GI) and extraintestinal clinical phenotypes, and explore potential serologic markers for risk stratification.

Interaction of a protecting wall with a soil massif in process extractions of foundation pit

RUDN Journal of Engineering Research, 2013
The computing procedure to determine the soil pressure on retaining structure and it’s displacements during earth excavation from a pit is developed. At the first stage the protecting construction (slurry wall, sheet piling, row of piles) is enclosed in a ground from the both sides, then the earth excavation from one side of the screen begins.

Digital modeling technique for complex heterogeneous strata and its application in numerical simulation of deep excavations

Yantu gongcheng xuebao
The reliability of deep excavation numerical simulation results hinges on the authenticity of the geological model. Current homogeneous 3D models often lead to prediction errors because they neglect spatial variability in soil properties.
