Matrix Suction in Silt and Sand Slopes. Significance and Practical Use in Stability Analysis

, 1997
Conventional stability analysis in unsaturated silt and sand slopes often results in unrealistically low factors of safety. The purpose of the study was to increase the knowledge and the understanding of the unsaturated zone and its matrix suction in ...

DETERMINATION OF THE MATRIX SUCTION OF LOW-PLASTICITY SILTS AND ITS CORRELATION WITH THEIR COLLAPSE POTENTIAL

Proceedings of International Structural Engineering and Construction
Soils are usually in a partially saturated state, meaning that both air and water occupy their voids. This condition can affect the stability of structures because it is closely related to wetting deformation (collapse). A low-plasticity silt (ML) composed of 45% kaolin with a liquid limit of 36% and a plasticity index of 10% was used in this study. In

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

The Anatomical Record, EarlyView.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

The influence of suction changes on the stiffness of railway formation

, 2011
Despite compacted soils being unsaturated, geotechnical design is predominantly based on saturated soils,despite it being known that differences exist between the behaviour of saturated and unsaturated soils.Suction in soils has been shown to increase ...

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

The Anatomical Record, EarlyView.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

Stability and receptivity analysis of flat-plate boundary layer with suction and blowing

, 2023
The effect of suction and blowing on the local stability of the flat-plate boundary layer is presented using non-normal theory. The 3D governing stability equations are derived using standard procedure in the form of normal velocity and vorticity.

Microstructure Analysis of the Alloy 625-nTiC Metal-Matrix-Composites Produced by Suction Casting

Materials Science Forum
Alloy 625 is a Ni-based superalloy with the main alloying elements being Nb, Cr, and Mo. It is known for its excellent corrosion resistance, good weldability, both high heat and creep resistance, and good strength. The current work presents the microstructure of Alloy 625-nTiC metal matrix composites (MMC) fabricated through suction casting.

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

The Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Incorporating 3D Suction or Discharge Plenum Geometry into a 1D Compressor Simulation Program to Calculate Compressor Pulsations

, 2012
A 3D calculated impedance transfer matrix method has been developed and demonstrated to provide accurate and efficient prediction of pressure pulsations in positive displacement compressors. The method is easily incorporated into 1D compressor simulation

The cranial, mandibular, and hyoid anatomy of softshell turtles (Trionychidae): A revised character list for phylogenetic analysis

The Anatomical Record, EarlyView.
Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...
