The site of Wonderwerk Cave, located in the Northern Cape Province between the towns of Danielskuil and Kuruman, preserves an extraordinary sequence that spans close to 2 million years of hominin activity (see Chazan and Horwitz, this volume, for an overview of the site). The earliest phases of occupation have only been recovered in Excavation 1 near the front of the cave in excavations carried...

The first step in mining activities is rock excavation in both mine development and production. Constant pressure for cost reduction and creating an improved/safe work environment for personnel has naturally resulted in increased use of mechanical excavation systems in many mining operations. Also, mechanical excavation and mining is more compatible with automation, meaning possibility of reduc...

Abstract Steel sheet pile walls are being widely used in civil engineering projects for support systems. Soil is not uniform in depth, sometimes may be exit loose or soft soil layer in various depth. This issue can cause different effects on ground surface displacements, forces and moments acting on sheet piles and struts during excavation procedure, compared with status that soil is uniform...

OBJECTIVES To assess the use of post-salvage radiotherapy prostate-specific antigen for early prediction of biochemical failure or clinical recurrence after salvage radiotherapy in recurrent prostate cancer patients after prostatectomy. METHODS From 2000 to 2011, 164 patients were treated with salvage radiotherapy alone for recurrent prostate cancer. Patients who received androgen deprivation...

We report on a study carried out within the 3D MURALE project, in which the complete workflow necessary for automatic recording, reconstruction and interactive visualization of artefacts on archaeological excavation sites has been tested. With state-of-the-art technologies from digital photogrammetry, computer vision and computer graphics a prototypical pipeline for recording, 3D modeling and v...

INTRODUCTION A significant proportion of patients undergoing salvage radiotherapy (RT) for biochemical recurrence (BCR) following radical prostatectomy (RP) may again experience BCR after salvage RT. Thus, we evaluated the clinical significances of different parameters on the biochemical outcome of RT in salvage setting. METHODS We reviewed the records of 212 patients who underwent salvage RT...

Salvage logging after natural disturbance has received increased scrutiny in recent years because of concerns over detrimental effects on tree regeneration and increased fine fuel levels. Most research on tree regeneration after salvage logging comes from fire-prone systems and is short-term in scope. Limited information is available on longer term responses to salvage logging after windstorms ...

BACKGROUND For a long time intraoperative cell salvage was considered not to be applicable in paediatric patients due to technical limitations. Recently, new autotransfusion devices with small volume centrifugal bowls and dedicated paediatric systems allow efficient blood salvage in small children. The purpose of this prospective non-randomised study was to determine the impact of intraoperativ...

This paper describes the design, construction and early performance of a retaining structure close to a subway tunnel in Barcelona. The excavation, about 16 m deep, was carried out in 2001 during the construction of a new hospital, and involved a rectangular area with the longer side (170 m) almost parallel to the tunnel. The design had to fulfil two requirements: first, the influence of the ex...
