Abstract: A multiple port network device, connected to a network, detects and records over which port of the multiple port network device other network devices communicate with the multiple port network device. A table is maintained in a memory. The table has entries which identify by which port of the multiple port network device other network devices communicate with the multiple port network device. The table is updated by monitoring packets received by the multiple port network device. When a packet is received by the multiple port network device, a port number over which port the multiple port network device received the packet is determined. Also, a source address of a network device from which the packet originated is determined. When the source address is not listed in the table, the table is updated with an entry for the source address which includes the port number.

Abstract: Automatic tracking of the topology of an extended local area network by augmenting a station address list kept by a bridge with a list of repeater numbers and repeater port numbers. The bridge periodically iterates through its list of stations to select a station address. The selected address table is forwarded to all of the repeaters connected to the bridge. The repeaters watch for the selected address appearing as a source address in a message on one of their ports. If the address is seen, they report the repeater port number back to the bridge. Because the repeaters are interconnected such that a predetermined port number is always used as the common port between repeaters, any possible ambiguities are eliminated.

Abstract: An apparatus for handling a patient's blood during a medical procedure which is convertible for use after the procedure for at least one further use. The apparatus comprises a reservoir having a port comprising at least one opening. A primary device, alignable with the port for adapting the reservoir for use during the procedure. The apparatus further comprises one or more secondary devices each alignable with the port means for adapting the reservoir for one or more further uses after the procedure. The primary device and the secondary devices are slidably mounted on the apparatus between tracks, with the primary device initially aligned with the port to allow the reservoir to be used during the medical procedure. The tracks allow the primary device to be moved out of alignment with the port and allow at least one of the secondary devices to be moved into alignment with the port so that the reservoir can be used after the medical procedure.

Abstract: Market segmentation in the cruise ship industry is an essential tool for securing a favourable market share. A case study of a mid-sized vessel operating from a ‘non-traditional’ port provides insights of the demographic and socio-economic characteristics of a cruise population. The questionnaire also supports the logic for a strong local/regional marketing effort and validates the rationale for the provision of a cruise service from a ‘non-traditional’ port.

Abstract: This invention relates to a method and an apparatus for sealing a port of a vessel, which apparatus comprises: (a) a seal for forming a gas-tight seal with the port to close off the port, (b) a chamber; and (c) a chamber sweeping gas for sweeping the chamber.

Abstract: The advance of intermodal transportation during the 1980s and the recent growth in container‐vessel dimensions have strengthened the rationale of the load center concept. Ports are assuming the role of a link in the total transport chain rather than a terminus and break of bulk point. Intermodality introduced new dimensions into port competition. The quality of a port's access to inland transport networks, particularly railroads and double‐stack trains, becomes a vital factor for shipping lines in their selection of load center ports in North America. Concentration of traffic in load centers in Europe and the United States does not necessarily imply a more concentrated port system, however. Total traffic has grown and is shared among transportation enterprises with different itineraries and different ports of transit.

Abstract: The Port of Baltimore has recently experienced alarming traffic trends. Most measures of port vitality have been going the wrong way—tonnage, ship calls, market share, steamship service. rail service. Baltimore has been squeezed by external forces and circumstances. Dergulated rail and truck rates have not favoured Baltimore, nor have railroad mergers that have led to rail traffic concentrations at rival seaports. Federal approval of dredging projects has been delaed. Crises in the labour market have created a climate of uncertainty. Global trade patterns and intermodel itineraries have shifted, again, it seems, not to Baltimore'advantage. Baltimore needs new public port policy recommendations. This paper explains some of the problems and offers preliminary suggestions.

Abstract: A data transmission apparatus having a junction and branching mechanism includes an arbitration control portion and a switching element. The arbitration control portion sets a state of the switching element based on an identifier included in each packet data. When identifiers in the packet data applied from a first input port and a second input port indicate branch destinations different from each other, the data are simultaneously transferred to a first output port and a second output port through the switching element. When both the identifiers in the packet data from the first and second input ports specify the same output port of the first and second output ports, the data is transferred to the specified port in their order of arrival.

Abstract: Ports are crucial links in global economic exchange. Structural modifications in the global economy have necessitated sequential morphological transformations in third-world port landscapes to accommodate each new emphasis of production in hinterlands. A four-stage temporal and descriptive model is proposed to examine relationships between structural evolution of the global economy and port-landscape changes at Belawan, the busiest international outerisland port of Indonesia. AS nodes linking land and maritime transportation, and as points of interdependent economic articulation between the Western core and non-Western periphery, third-world port facilities develop and operate in a manner that reflects the long-term structural evolution of the global economy. Colonially induced, sequential structural changes in investment, production, division of labor, and trade have come in response to the progressive economic maturation of industrial countries (Wallerstein 1979). Each stage has been accompanied by innovations in transportation that allow for reduced costs, the subsequent spread of capitalist production, and the incorporation of peripheral regions into a single production system (Mandel 1978, 50-51). This article interprets the long-term evolution of port morphology as a landscape expression of global economic relationships. The premise is that each stage in the penetration by Western economic interests and accompanying transportation technologies into peripheral resource regions engenders parallel changes in the morphologies of third-world port landscapes. With the implicit assumption that economic growth in the core depended on materials and markets of the periphery and that economic growth there required capital investment from the core (King 1990, 45), the morphology of Western ports was reproduced in the third world to promote the efficient articulation of global transportation. Interpreting and understanding the continuum of port-landscape evolution at one node of the global transportation system are possible only with reference to the production system of which that port constitutes one element. The port of Belawan on the Indonesian island of Sumatra provides an instructive case study. Belawan functions as the primary outport for the most productive plantation region in the country (Fig. 1). From inauspicious beginnings in the mid-nineteenth century, northern Sumatra by the early 1900s became known as the East Coast Plantation District. More importantly, West* DR.

Abstract: Portal verification has led many radiation therapy departments to implement policies of taking weekly port films for every patient. This has caused some to question the impact of port film dosage, once considered negligible. Using clinical data from 100 patients, this article examines the impact of port film dosage and offers suggestions for documentation and alternatives for decreasing dosages.

Abstract: It has long been believed that the small port at Dor along the Israeli coast was overshadowed by a much larger port 13 kilometers to the south at Caesarea. Ancient sources report that Dor's decline began in 22 B.C.E. and ended with the site being virtually abandoned by 390 C.E. Recent research, however, has revealed an intriguing array of maritime installations along a 1-mile stretch of shoreline that, along with a plethora of multi-period material, indicates Dor may have been much more active than previously thought.
