Wall thickness uniformity of railway hollow shafts by cross-wedge rolling

工程科学学报, 2015
Wall thickness uniformity is an important quality criterion of railway hollow shafts by multi-wedge synchrostep cross wedge rolling. The stable rolling condition of railway hollow shafts in this rolling process is analyzed,and a flattening instability ...

THE THICKNESS OF THE WALL OF THE RED BLOOD CORPUSCLE [PDF]

Journal of General Physiology, 1935
Fricke's assumption, that the dielectric constant of the erythrocyte wall is 3, is discussed. The assumption is approximately correct in the case of a solid layer of any thickness, and in the case of a liquid layer of not more than bimolecular thickness. For liquid layers of greater thickness the dielectric constant may be several times greater than 3.

Age-Related Concentric Remodeling and Sex-Dependent Dimensional Variation in Left Ventricular Geometry: A Cardiac Magnetic Resonance Study

Tomography
Background/Objectives: Left ventricular (LV) geometry reflects structural adaptation to aging and biological sex. While cardiac magnetic resonance (CMR) provides precise morphologic assessment, most prior studies have focused on volumetric and mass-based

Increased vein wall thickness in Behçet disease

Journal of Vascular Surgery: Venous and Lymphatic Disorders, 2019
Lower extremity (LE) deep venous thrombosis (DVT) is the main feature of vascular involvement in Behçet disease (BD). We thought that vein wall thickness (VWT) could be a surrogate marker for venous inflammation and hence predict future vascular involvement.

Experimental study on determining the degree of bone healing by wall thickness ratio analysis

Journal of Orthopaedic Surgery and Research
To verify the reliability and accuracy of wall thickness ratio analysis to determine the degree of bone healing, fracture models were established with 6 beagles. X-ray, micro-CT, and CT scans were performed at 24 weeks.

Thin and thick bubble walls II: expansion in the wall width

Journal of Cosmology and Astroparticle Physics
Abstract We study the dynamics of a cosmological bubble wall beyond the approximation of an infinitely thin wall. In a previous paper, we discussed the range of validity of this approximation and estimated the first-order corrections due to the finite width. Here, we introduce a systematic method to obtain the wall equation of motion and
