PM2.5, total suspended particles (TSP) and gas phase samples were collected at two sites of Taizhou, a major e-waste dismantling area in China. Concentrations, seasonal variations, congener profiles, gas-particle partitioning and size distribution of the atmospheric polychlorinated biphenyls (PCBs) were studied to assess the current state of atmospheric PCBs after the phase out of massive histo...

It is necessary to develop a useful application to use big data like as AIS for safety and efficiency of ship operation. AIS is very useful system to collect targets information, but this information is not effective use yet. The evaluation method of collision risk is one of the cause disturb. Usually the collision risk of ship is evaluated by the value of the Closest Point of Approach (CPA)...

The volume of maritime traffic is increasing with the growing global trade demand. effect growth especially observed in narrow and congested waterways as an increase ship-ship encounters, which can have severe consequences such collision. This study aims to analyze validate patterns risky encounters provide a framework for visualization model variables explore patterns. Ship–ship interaction da...

Maritime Domain Awareness is an initiative started to help each sea-bordering country improve its understanding of its Exclusive Economic Zone. A country that improves its Maritime Domain Awareness ensures that activities such as piracy and Illegal, Unreported and Unregulated fishing are identified more quickly and the appropriate actions for each are taken. For instance, having better awarenes...

This paper relates the development of a French incoherent scatter system which started its operations in 1965. This development took place several years after the initial implementation of such systems in the United States, in Peru and in the United Kingdom. The French system, owing to its bistatic configuration and the use of continuous waves, differed from the previous ones. These characteris...

In the Japan Power Demonstration Reactor decommissioning program remote handling technologies were developed that could be successfully applied to dismantling the core components and verified by successful work accomplishment. However, wider applications and intelligence to the work process were required to perform dismantling work efficiently. The dual arm systems and their control mechanism h...

BACKGROUND We aimed to evaluate a new drug-free fully bioresorbable lactic acid-based scaffold designed to allow early dismantling synchronized with artery wall healing in comparison with a bare metal stent (BMS). METHODS AND RESULTS Twenty-three BMS (3.0×12 mm) and 36 lactic acid-based bioresorbable scaffolds (BRS, 3.0×11 mm) were implanted in porcine coronary arteries. QCA and optical coher...
