PURPOSE Small injection ports for mice are increasingly used for drug testing or when administering contrast agents. Commercially available mini-ports are expensive single-use items that cause imaging-artifacts. We developed and tested an artifact-free, low-cost, vascular access mini-port (VAMP) for mice. PROCEDURES Leakage testing of the VAMP was conducted with high speed bolus injections of...

in this paper, we are going to investigate the growth of the iranian maritime transport with a focus mainly on the north - south transit corridor, review of dry ports in order to support the iranian container terminals at the south ports in order to increase the volume of container storages at the terminals. for the purpose of assessing the outcome of port operational management, the balanced s...

The 8255A programmable peripheral interface PPI) implements a general-purpose I/O interface to connect peripheral equipment to a microcomputer system bus. The core’s functional configuration is designed by VHDL code and designed input signal (Test bench) for PPI 8255, which is generated by VHDL code. Simulated result is verified for one 8bit Peripheral Ports Ports A, three programming modes for...

One of the most promising solutions for Broadband ISDN is the Asynchronous Transfer Mode(ATM). Many ATM switch designs have been proposed, which provide a high throughput and a low cell loss probability. The most common design is based on multistage interconnection networks. In this type of design, dedicated buffers may be at either the input ports or the output ports, or at both input and outp...

This paper is an empirical attempt verifying the interplay between political change, fleet nationality, and the evolution of shipping networks. North Korea offers a good example of a socialist maritime country that experienced much contrasted geopolitical contexts during the last two decades. A database of vessel movements between North Korean ports and other ports is analyzed. Main results sho...

A newly developed heavy duty diesel engine in dual fuel mode of operation has been studied in detail. The main fuel would be natural gas and diesel oil as pilot injection. The importance and effects of mixture preparation and formation through ports, valves and in cylinder flow field with different swirl ratio and tumble on diesel combustion phenomena is an accepted feature which has been studi...

UNLABELLED Since the first laparoscopic cholecystectomy (LC), laparoscopic approach has been the focus of surgical authorities and continued its technical revolution. With increasing surgical experience, a trend toward even more minimally invasive approaches has led to laparoscopic surgery to new inovations. Current surgical procedures are: four ports (4PLC), still the gold standart technique, ...

We consider the role of switching in minimizing the number of electronic ports (e.g., SONET ADMs) in an optical network that carries sub-wavelength traffic. Providing nodes with the ability to switch traffic between wavelengths, such as through the use of SONET cross-connects, can reduce the required number of electronic ports. We show that only small switches at multiple switching nodes are ne...
