A seven-port wave-correlator based vector network analyzer is proposed. The seven-port wave-correlator is a combination of two six-port wave-correlators which share common components. Furthermore, the complex wave ratio measurement accuracy is improved since the input signals can be directly detected by the side-arm ports. A seven-port wave-correlator is fabricated using microstrip branch line ...
AIMS The aim of this study was to evaluate the ideal timing of PORT in the management of completely resected (R0) Stage IIIA-N2 NSCLC. PATIENTS AND METHODS Between January 2008 and December 2015, patients with known histologies of pathologic Stage IIIA-N2 NSCLC who underwent R0 resection and received PORT concurrent with or prior to two sequential cycles of chemotherapy ("early PORT") or with...
Port wine stains are benign but cosmetically devasting congenital angiomas. The argon laser is a therapeutic device newly applied to this condition. Our program was begun 6 years ago. From the beginning, the study was conceived as a clinical investigation of both the port wine stain and its argon laser therapy. A total of 218 patients with port wine stains have been studied and many aspects of ...
PURPOSE Single-port laparoscopic splenectomy has been performed sporadically. The aim of this study is to assess our experience with single-port laparoscopic splenectomy compared to conventional multiport laparoscopic surgery for the usual treatment modality for various kinds of splenic disease. METHODS Between October 2008 to February 2014, 29 patients underwent single-port laparoscopic sple...
This paper details the optimisation of bulk material port handling systems through the use of a metaheuristic based approach. The effective management of port systems requires effective solutions for the design, operation and maintenance of these facilities. This has to be achieved through a reduction in financial costs, and an increase in the utilisation of equipment and other resources. The o...
OBJECTIVES With increasing surgeon experience, laparoscopic cholecystectomy has undergone many refinements including reduction in port number and size. Three-port laparoscopic cholecystectomy has been reported to be safe and feasible in various clinical trials. However, whether it offers any additional advantages remains controversial. This study reports a randomized trial that compared the cli...
Introduction: Radiation therapy is one of the methods of cancer treatment. In this method, it is necessary to avoid harming the healthy tissues of the patient which is in the vicinity of the target, as much as possible. Treatment verification is one of the most important steps of radiation therapy which has two usual methods, using Port film and EPID. The accuracy and precision of treatment in ...
OBJECTIVES Single-port surgery is a rapidly advancing technique in laparoscopic surgery. Currently, there is limited evidence on the learning curve and practicality of performing single-port laparoscopic cholecystectomy. METHODS Single-port cholecystectomy was performed on 20 consecutive patients for biliary dyskinesia, symptomatic cholelithiasis, or acute cholecystitis. The Tri-Port was plac...
Due to the increasing freight volumes passing via seaports checkpoints, and increasingly reported delays in customs clearance procedure, dry port, emerged as one kind of solution to such situation, instead of extending the port scale under limited land use. The place located with dry port (sometimes inland port) can solve not only the congestion embarrassment faced by connected seaport, but als...
