Background and purpose: Only limited data exist on the outcome of curative radiotherapy in patients who develop a second primary lung tumour after pneumonectomy. The treatment of eight such patients is described. Materials and methods: The case records of patients who underwent curative radiotherapy for stage I non-small cell lung cancer after a previous pneumonectomy were reviewed. Treatment w...

Pectus arcuatum is a rare complex chest wall deformity. A 31-year-old female presented with a severely protruding upper sternum combined with a concave lower sternum. We planned a modified Ravitch-type operation. Through vertical mid-sternal incision, chondrectomies were performed from the second to fifth costal cartilages, saving the perichondrium. Horizontal osteotomy was performed in a wedge...

Nearly 100 tests were performed with prototypical melters and off-gas system components to investigate the extents to which technetium is incorporated into the glass melt, partitioned to the off-gas stream, and captured by the off-gas treatment system components during waste vitrification. The tests employed several simulants, spiked with 99mTc and Re (a potential surrogate), of the low activit...

Feasibility tests were initiated to determine if the zirconium in commercial used nuclear fuel (UNF) cladding can be recovered in sufficient purity to permit re-use, and if the recovery process can be operated economically. Initial tests are being performed with unirradiated, non-radioactive samples of various types of Zircaloy materials that are used in UNF cladding to develop the recovery pro...

OBJECTIVE To determine and compare failure, re-operation, and complication rates of all generations and techniques of autologous chondrocyte implantation (ACI). METHODS A systematic review of multiple medical databases was performed according to PRISMA guidelines. Levels I-IV evidence were included. Generations of ACI and complications after ACI were explicitly defined. All subject and defect...

This paper describes the components (“software agents”) that are needed in an autonomous robotic assembly system. Such a system is called “autonomous” if it is able to cope with all uncertainties in the real-world execution (control and sensing) of an assembly task that was planned off-line, and with the (re)planning itself. For each component, the paper answers the following three questions: W...

A 53-year-old male with adenocarcinoma of the rectum with metastasis to liver and porta hepatis region underwent biliary stenting due to aggressive distal common bile duct stricture. At the time of planned stent exchange, the guidewire could not be re-introduced, despite several techniques, including the SpyScope(®) system. A small fistula was noted by contrast fluoroscopy extending between pro...

In the last decade, increasing use of NanoSats and CubeSats has made re-entry capsule an emerging research field needing updates in configuration technology. particular, door to advancements terms efficiency re-usability been opened by introduction inflatable and/or deployable aerodynamic brakes on-board electronics for active control. Such technologies allow smaller sizes at launch, controlled...
