PURPOSE To present the midterm follow-up results of subcutaneous venous chest ports in adult patients. MATERIALS AND METHODS Between January 2001 and November 2005, 476 subcutaneous venous chest ports were placed in 472 adult patients. Five patients underwent port implantation twice. All the ports had single lumen catheters. The procedures were performed under intravenous sedation as well as ...

We introduce ports, an alternative to streams, as communication support for object-oriented programming in concurrent constraint logic programming languages. From a pragmatic point of view ports provide e cient many-toone communication, object identity, means for garbage collection of objects, and opportunities for optimised compilation techniques for concurrent objects. From a semantic point o...

A novel joint multilayer restoration scheme for IP-over-DWDM networks is proposed, where the restoration algorithm manages network resources from both the IP layer and the optical layer in a synergistic manner. Since IP router ports are typically more expensive than optical switch ports, the essence of the approach is to attempt to reuse IP service ports or the service wavelengths associated wi...

Laparoscopic cholecystectomy is now the procedure of choice in all the gall bladder diseases and there is increase in the skills of surgeons with newer equipment. Normally the laparoscopic cholecystectomy is performed by using four ports or three ports. Two ports laparoscopic cholecystectomy is rarely performed as it demands greater expertise and skills. Also this technique is less expensive an...

Private Sector Development Department ▪ Vice Presidency for Finance and Private Sector Development Before Argentina began reforming port operations in 1990, its ports were costly and inefficient. Restrictive labor regulations led to high labor costs. Most ports were open rather than terminal-based, leading to inefficient operating practices and unnecessary costs for cargo handling and storage. ...

l Biofoulingmitigationmeasures for optical ports can extend the duration of oceanographic deployments, but there have been few quantitative studies of field performance. Results are presented from a 4-month field test of a stereo-optical camera system intended for long-term environmental monitoring of tidal turbines. A combination of passive (copper rings and ClearSignal antifouling coating) an...

Now-a-days, with the increase in the use of resources over a network, many people are failing to access their required resources. This is caused due to unavailability of ports. Unfortunately, reserved ports can be accessed only when the ports are free. If there is a communication link, some ports will regret to accept any new incoming connections and we need to wait until other connection close...

The operational performance of container ports has received more and more attentions in both academic and practitioner circles, the performance evaluation and process improvement of container ports have also been the focus of several studies. In this paper, Data Envelopment Analysis (DEA), an effective tool for relative efficiency assessment, is utilized for measuring the performances and bench...

This paper proposes an idea to modify the conventional Wilkinson power dividers to have physically spaced output ports. The well-known internal resistor of Wilkinson power divider is now connected to output ports by two additional transmission lines to create a triangular shape power divider. Several modified power dividers are designed at frequency of 1.0 GHz and one of them is fabricated and ...

We investigated the risk factors for venous thrombosis in cancer patients with implantable ports undergoing chemotherapy. One hundred and seventy one ports were placed in a central ("chest ports") and 84 in a peripheral vein ("arm ports"), 181 received prophylactic nadroparin and 10 coumarin. Clinically overt thrombosis was confirmed by ultrasound or angiography. Catheter-related thrombosis inc...
