Tunnels are an important component of the transportation and utility system cities. They being constructed at increasing rate to facilitate need for space expansion in densely populated urban areas mega-cities. The circular rectangular tunnels cannot completely meet requirements underground exploitation regarding cross-section. Sub-rectangular recently used overcome some drawbacks terms low uti...

Accuracy of hydrogeological and geotechnical investigation in place shaft sinking is a key factor for selection method design the lining. The following work presents influence rising level accuracy geological data gathered area Silesian Coal Basin technical projects lining technology its sinking, which have been changing over years. initial project was repeatedly modified. Each modification eve...

OBJECTIVES Current methods of monitoring chronic synovitis in a single joint rely on clinical examination derived indices, such as the detection of synovial thickening. This study aimed to develop a reproducible method for quantifying the volume of synovial lining in chronic synovitis using contrast enhanced magnetic resonance (MR) imaging. METHODS The knees of 18 patients with chronic synovi...

BACKGROUND Initial investigations demonstrated a deficiency of glutathione (GSH) in the epithelial lining fluid (ELF) of HIV-seropositive patients. In a recent study, our laboratory was unable to document such a deficiency. The current study was performed in an attempt to reconcile those disparate findings. STUDY OBJECTIVES To determine if ELF GSH decreases over time in asymptomatic HIV-serop...

The extracellular lining of the lungs is reviewed. The pulmonary extracellular lining is a complex mixture of phospholipids, proteins and carbohydrates which is absolutely essential for the maintenance of normal pulmonary functions such as gas exchange. Without the lining the lungs would collapse. Alterations in the pulmonary extracellular lining may underlie some disease conditions induced by ...

This paper takes the surrounding rock of deep tunnel as research object and considers action mechanism under influence seepage. Based on Mohr-Coulomb criterion, stress buried is analyzed by a convergence constraint method. elastic-plastic solution, nonlinear solution interaction between lining structure considering effect seepage force proposed, radius plastic zone obtained. The relationship di...

Objective—To demonstrate the expression of laminins (Lns) and their integrin (Int) receptors in diVerent synovial samples and synovial membrane-like interface tissues from well fixed and aseptically loosened total hip replacement (THR), and the potential role of Ln-Int interaction in the production of collagenases and cytokines. Methods—Immunohistochemical staining was done to detect the distri...

Mechanical behaviour of the waste body controls many aspects of landfill lining system design and performance, including stability issues and integrity of the geosynthetic and mineral lining components. Knowledge of the likely ranges of waste mechanical properties is required to assess potential modes of failure and hence to design the landfill engineering measures. This paper provides a summar...
