This paper presents a six-port network over an ultrawideband (UWB) of 2–8GHz. Its key component is the six-port junction, which consists of a Wilkinson power divider and three 3-dB quadrature couplers. This six-port junction is accomplished in a low dielectric constant substrate (Rogers RT/duroid 5880). Multi-section impedance transformation is applied in the power divider, and the quadrature c...

Usage of the new and alternative clean fuel is becoming a hot topic in marine transportation in accordance with environmental regulations of I.M.O. Using L.N.G as the ship fuel is a reliable and long term solution for environmental issues. Iran owing to its large number of natural gas fields and unique geographical position, has adequate potential to provide services to shipping fleets. Finding...

The technology of intravenous catheter access ports has evolved from open ports covered by removable caps to more-sophisticated, closed versions containing mechanical valves. We report a significant increase in catheter-related bloodstream infections after the introduction of a new needle-free positive-pressure mechanical valve intravenous access port at our institution.

A small-scale squid hand-jig fishery targeting the squids Loligo vulgaris and Loligo forbesi exists in the northwestern Iberian Peninsula. Its importance is evaluated using a model based on a short survey of fishery statistics. A total of 46 ports in Galicia operate this fishery. These ports were classified into three categories, according to characteristics relevant to the length of season in ...

Introduction: Multicasting in high-capacity Internet has not been resolved yet. Multicast traffic that we consider has one source and multiple destinations. There are two main approaches for forwarding of the multicast traffic through a crossbar. In the case of unicast crossbars, an input has to replicate a multicast packet, as many times as there are output ports to which that packet is bound....

BACKGROUND Subcutaneous ports are commonly used for vascular access in patients with cancer undergoing chemotherapy. OBJECTIVES To determine the incidence of catheter-related infection and to assess the efficacy of catheter salvage in subcutaneous ports. METHODS We retrospectively reviewed 300 subcutaneous single-lumen chest ports inserted by interventional radiologists in 294 patients betw...

Australian ports serve diverse and extensive activities, such as shipping, tourism and fisheries, which may all impact the quality of port water. In this work water quality monitoring at different ports using a range of water quality evaluation indices was applied to assess the port water quality. Seawater samples at 30 stations in the year 2016-2017 from six ports in NSW, Australia, namely Por...

In this study, we aim to determine the application of enhanced recovery after surgery (ERAS) in single incision and multiple ports laparoscopic hepatectomy. Ninety-five patients undergoing laparoscopic left lateral hepatectomy for hepatocellular carcinoma (HCC) were included and divided into three groups: pre-MPH group (n=35), received pre-ERAS multiple ports procedures; SPE group (n=27), recei...
