Abstract Background Totally implantable central venous access devices (ports) have been available for over 10 years, but have not been achieved widespread use in pediatric oncology patients. Ports facilitate the administration of chemotherapy in children with cancer. Materials and Methods In this study, early complications of implantable central venous access devices in children with different ...

The international business environment of port logistics has changed drastically in the last few decades. The increase in international trade, advent of ultra-large vessels, changes in customer needs and development of new cargo handling technologies, the competition between container ports has become very severe in the last few decades and ports started to invest in their infrastructure and in...

The group theoretical aspect of the description of passive lossless optical four-ports (beam splitters) is revisited. It is shown through an example, that this approach can be useful in understanding interferometric schemes where a low number of photons interfere. The formalism is extended to passive lossless optical six-ports, their SU(3)-theory is outlined.

In delivering safe care to their patients, oncology nurses should be familiar with the proper use and maintenance of implanted ports. Yet, despite the ubiquitous presence of implanted ports, accessing techniques and patency maintenance remain controversial. Additional research is needed to establish practices based on evidence.

Management of nautical tourism ports, by having general appropriate characteristics as well as characteristics related to business skills, can encourage development of related ports, which may result in direct and indirect impact on economy of the Republic of Croatia. For the purposes of this research work, there has been done a survey regarding management of eighteen (18) nautical tourism port...

This paper describes a new architecture for a multicast ATM switch scalable from a few tens to a few thousands of input ports. The switch, called the Abacus switch, has a nonblocking switch fabric followed by small switch modules at the output ports. It has buffers at input and output ports. Cell replication, cell routing, output contention resolution, and cell addressing are all performed in a...
