Segment reinforcement corrosion can cause bearing-capacity degradation of shield tunnel, which is unsafe for the metro operation. Therefore, a three-dimensional computational model was proposed in this paper to study rate and rust expansion form segment by combined action soil loading, chloride ion stray current. The results show that arch waist steel middle larger than ends. appears be an ecce...

Regarding the mathematical study of Inoue et al. 1, it is appropriate to mention the study by Cheng (Apud Collins) 2 published more than half a century ago in which the width of the circular epidural space (EP) and thickness of the dura mater (DM) were measured. According to Cheng 2, the axial width of EP at L2-L3 is 6 mm and if the puncture is 30 degrees to the skin, the puncture safety margin...

We describe a technique for repairing the ventricular septal perforation 10 days post acute anteroseptal myocardial infarction using the modi®ed infarction exclusion method. The repair involves endoventricular circular patch plasty and application of gelatin±resorcinol± formaldehyde biological glue in the space between a Te ̄on felt patch on the infarcted septum and a bovine pericardial patch in...

Case 1. A male, who had melaena at 31 months and again a fortnight later, was admitted to hospital on December 26, 1958, when 14 months old. He was shocked with a vague mass across the lower abdomen. On the following day, after a blood transfusion, laparotomy was carried out and perforation of the ileum was closed. Penetration of rectus sheath was present. Occult blood remained positive. A seco...

Eccentric connectivity index has been found to have a low degeneracy and hence a significant potential of predicting biological activity of certain classes of chemical compounds. We present here explicit formulas for eccentric connectivity index of various families of graphs. We also show that the eccentric connectivity index grows at most polynomially with the number of vertices and determine ...

The evolution of many close binary and multiple star systems is defined by phases mass exchange interaction. As these evolve into contact, tidal dissipation not always sufficient to bring them circular, synchronous orbits. In cases, encounters increasing strength occur while the orbit remains eccentric. This paper focuses on outcomes passages in eccentric Close excite dynamical oscillations abo...

BACKGROUND Long-term endurance sport practice leads to eccentric left ventricular hypertrophy (LVH). We aimed to compare the new 4-tiered classification (4TC) for LVH with the established 2-tiered classification (2TC) in a cohort of normotensive non-elite endurance athletes. METHODS Male participants of a 10-mile race were recruited and included when blood pressure (BP) was normal (<140/90 mm...

In this paper, a cylindrical aluminum sample with an eccentric circular hole was prepared, and ultrasonic measurements were carried out by experimental means. The measurement area limited to plane edge perpendicular the axis of component. measured waveform data input into formula approximate correction method, section image obtained using modified Born approximation (MBA) method. Then, three-di...

A 30-year-old carpenter accidentally impaled his own left eye with a 5 cm staple ejected from a pneumatic gun. Entering the globe off-axis, the stainless steel staple caused a vitreous hemorrhage. On the day of injury, the staple was removed surgically. The vitreous hemorrhage cleared rapidly enough to permit laser treatment around the equatorial retinal perforation site. Visual acuity improved...
