PURPOSE Early salvage radiotherapy following radical prostatectomy for prostate cancer is commonly advocated in place of adjuvant radiotherapy. We aimed to determine the optimal definition of early salvage radiotherapy. MATERIALS AND METHODS We performed a multi-institutional retrospective study of 657 men who underwent salvage radiotherapy between 1986 and 2013. Two comparisons were made to ...
Radiotherapy is the main salvage option after primary radical prostatectomy. Radical prostatectomy, cryosurgical ablation and high-intensity focused ultrasound are the main salvage options after primary radiotherapy. After primary radiotherapy, long-term oncological outcome of salvage radical prostatectomy and salvage cryosurgical ablation is fairly comparable with the results of primary radica...
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...
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...
