Total oxygen analysis, chemical or electrolytic extraction and optical microscope with image analyzer are common methods to measure the cleanliness of steel. A re-melting technique was developed to float out inclusions and be examined under SEM or Cathodoluminescence microscopy. Evaluation of inclusions by optical emission spectrometer, ultrasonic tests after hot rolling, slab milling and defect mapping as well as a computer-controlled SEM analysis are described. As a result, the source causes of defects may be identified and countermeasures developed. Tundish nozzle clogging is quantified by a nozzle clogging factor, which is monitored on-line. Inclusion characterization and the implementation of a clean steel practice have led to a reduction of nozzle clogging and an increased cast string length with improved steel quality.

Based on the current Service-Oriented Architecture （SOA）, this paper proposes a new collaborative software design methodology in an SOA Environment： the Global Software Enterprise （GSE）. The current SOA is producer-centric, in which the service providers publish services that they produce and let the consumers to search avail- able services to compose their applications. GSE is build on top of Consumer-Centric SOA （CCSOA）, in which the application builders publish their application requirements for the service providers to follow when producing or customizing services to support the application. This new methodology reduces the workload and improves the application description capability of the service consumers. It also extends the capacity of design and code sharing, and thus further improves the software productivity. This paper presents the concepts, architecture, enabling techniques, and illustrative examples of collaborative software design in GSE.

Nonetheless, no differences in cognitive performance were observed between the 3 ***: These findings indicate that the mode of sport training, which results in either high cardiovascular or high motor fitness, bears no relationship to measures of general cognition in elite athletes. The present findings suggest that coaches and athletic trainers should be encouraged to monitor athletes' stress levels during training in order to maximize the beneficial effects of such training on general cognitive performance.
