Pressure Lubricated Deep Drawing : Conclusion

Bulletin of JSME, 1965
Continued from the preceding research, the hydrostatic counter-pressure which actuated upon the material being drawn into the die chamber was investigated in detail and it was made possible to predict the pressure throughout a process. This prediction is necessary for a project of this process to be successful.

Network Localization of Fatigue in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Fatigue is among the most common symptoms and one of the main factors determining the quality of life in multiple sclerosis (MS). However, the neurobiological mechanisms underlying fatigue are not fully understood. Here we studied lesion locations and their connections in individuals with MS, aiming to identify brain networks ...

Changes in Immune‐Inflammation Status and Acute Ischemic Stroke Prognosis in Prospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Inflammation is a critical risk factor for poor outcomes in cerebral infarction. Prior studies focused primarily on baseline inflammation status, neglecting dynamic longitudinal changes. We try to investigate the association between immune‐inflammation status alterations and stroke prognosis, and evaluated three systemic biomarkers'

Sheet Forming via Limiting Dome Height (LDH) Test: Influence of the Application of Lubricants, Location and Sheet Thickness on the Micro-Mechanical Properties of X8CrMnNi19-6-3

Lubricants
This work is concerned with forming, specifically deep drawing, and its influence on the micro-mechanical properties of sheet metal. In practice, there are several applications in which fractions can occur due to weak spots in the deep-drawn sheet metal,

Effect of transverse pre-stretching before deep drawing on the surface ridging resistance of 17%Cr ultra-purified ferritic stainless steel

工程科学学报, 2015
Cup-drawing test was performed to study the effect of transverse pre-stretching, namely 3%, 6%, 9% and 12% deformation, on the surface ridging resistance during deep drawing of a 17% Cr ultra-purified ferritic stainless steel cold-rolled annealed sheet ...

Exploratory Analysis of ELP1 Expression in Whole Blood From Patients With Familial Dysautonomia

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Familial dysautonomia (FD) is a hereditary neurodevelopmental disorder caused by aberrant splicing of the ELP1 gene, leading to a tissue‐specific reduction in ELP1 protein expression. Preclinical models indicate that increasing ELP1 levels can mitigate disease manifestations.
