Development of Lumbar Spinal Stenosis Caused by Lumbar Vertebral Compression Fracture

open access: yes, 2004
Spinal stenosis is a narrowing of the spinal canal by a combination of bone and soft tissues, which causes mechanical compression of spinal nerve roots.Diagnosis is made by computerized tomography, myelography, or magnetic resonance (MR) imaging. The aim

Pharmaceutical powder technology : towards a science based understanding of the behavior of powder systems [PDF]

open access: yes, 2006
Microcrystalline cellulose is one of the most useful fillers for direct compression. Cellulose in general consists of an amorphous part and a crystalline part, which can exist in two polymorphic forms: cellulose I and cellulose II.

Slip Localization Intensification Mediated by Grain Boundary Sliding in a Polycrystalline Nickel‐Based Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
The temperature dependence of fatigue behavior in nickel‐based superalloys is investigated through high‐resolution measurements of plastic localization. While increasing temperature reduces localization and enhances fatigue performance in René 88DT, Inconel 718 exhibits a sharp degradation at intermediate temperature due to intensified slip ...

Fatigue Crack Initiation and Growth in Nanocrystalline Ni at Multiple Length‐Scales

open access: yesAdvanced Engineering Materials, EarlyView.
Overview of miniaturized in situ SEM fatigue setup and resultant fatigue crack growth data for nanocrystalline Ni. The presented study focuses on the analysis of fatigue crack growth rate (FCGR) in focused ion beam‐notched microcantilevers prepared from nanocrystalline (NC) Ni as a model material.

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

A new data reduction scheme to obtain the mode II fracture properties of Pinus Pinaster wood

open access: yes, 2006
In this work a numerical study of the End Notched Flexure (ENF) specimen was performed in order to obtain the mode II critical strain energy released rate (GIIc) of a Pinus pinaster wood in the RL crack propagation system.

Fragment Compression through Distal Locking Hole by Screw with Washer: A Supplement to Nailing in Distal Tibia Fractures [PDF]

open access: yesJournal of Foot and Ankle Surgery (Asia Pacific)
Introduction: Distal tibial metadiaphyseal fractures are challenging fractures that need multiple principles of fixation for optimal stability. Conventionally, when the distal locking screw hole of tibia interlock nail coincides with the fracture site ...

Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation
