The confined water is a very important risk source for deep excavation especially in saturated soft soils because failure in control measurements will lead serious consequence not only for the project itself but also for adjacent buildings. There are many risk sources that have close relation with the risks in deep excavation relating to the confined water. Based on the probability and losses o...

INTRODUCTION At the invitation of the Dean and Chapter of Rochester Cathedral, the Canterbury Archaeological Trust carried out an excavation within the Lay cemetery of the Cathedral during April and May 1990. This project, funded by the Cathedral authorities, was undertaken before work began on the consolidation of the foundations of the Chair Store, which is situated between the west side of t...

The design and construction of shallow-buried tunnels in densely populated urban areas involve many challenges. The ground movements induced by tunneling effects pose potential risks to infrastructure such as surface buildings, pipelines, and roads. In this paper, a case study of the Zhongjie subway station located in Shenyang, China, is examined to investigate the key construction techniques a...

M itral annular velocities derived from pulsed tissue Doppler imaging (TDI) were recently demonstrated to complement the analysis of systolic and diastolic left ventricular (LV) performance in different clinical settings. 2 The early diastolic mitral annular velocity (E9) was found to behave as a preload independent index of relaxation. The mitral E/E9 ratio (that is, the mitral E velocity corr...

To apply annular output beams emitted from an unstable resonator to a multiple-pass cell (MPC) for Raman conversion, we studied the mode-matching condition of non-Gaussian beams to a MPC using beam propagation analysis based on Laguerre-Gaussian functions. During transits of the MPC, the radial profile of an annular beam changes between annular and Airy patterns. Although such behavior indicate...

The annular pancreas is a rare congenital anomaly in which a ring of the pancreas parenchyma surrounds the second part of the duodenum. Malignant tumors are extremely rare in patients with an annular pancreas. A 64-year-old man presented with appetite loss and vomiting. Abdominal contrast-enhanced computed tomography (CT) indicated pancreas parenchyma surrounding the second part of the duodenum...

BACKGROUND Pulmonary nodular excavation should firstly evoke tuberculosis or necrosis broncho-pulmonary tumor, particularly: epidermoid carcinoma. The case discussed here illustrated these difficulties in patients with rheumatoid arthritis (RA). CASE PRESENTATION A 63-year-old woman was presented with a-three-year history of RA and a recent discovery of an excavated pulmonary nodule. Initial ...

This paper describes technologies we have developed to perform autonomous large-scale off-world excavation. A scale dragline excavator of size similar to that required for lunar excavation was made capable of autonomous control. Systems have been put in place to allow remote operation of the machine from anywhere in the world. Algorithms have been developed for complete autonomous digging and d...

OBJECTIVE To test the hypothesis that diastolic mitral annular motion velocity, as determined by Doppler tissue imaging and left ventricular diastolic flow propagation velocity, is related to the histological degree of heart transplant rejection according to the International Society of Heart and Lung Transplantation (ISHLT). METHODS In 41 heart transplant recipients undergoing 151 myocardial...

The role of docosahexaenoic acid (DHA) in the fluidity of the annular lipid regions and their associated membrane-bound proteins is still not as well understood as that in the global (bulk) lipid regions. We therefore studied the effects of dietary DHA on the relationship between annular and global lipid fluidity and membrane-bound enzymes such as 5'-nucleotidase and Mg(2)+-ATPase in the rat bi...
