Slag entrainment is a critical issue in continuous casting caused by an unstable interface between liquid steel and molten slag which can cause detachment of slag leading to non-metallic inclusions. Non-metallic inclusions are a common source of internal and surface defects in final products that degrade mechanical properties such as toughness and fatigue life as well as causing poor surface quality [1]. During entrainment, most of the detached slag droplets go back to the slag bed due to buoyancy and argon bubbling; however, some inclusions are entrapped near the solidified shell which can cause surface/internal defects depending on where they are captured. If they are captured in the mold, these will appear as surface defects after scarfing; whilst they will appear as internal defects in the rolled plate if trapped further downstream in the product core., QC 20200611

Single-electron (SC) and double-electron capture (DC) in collisions of metastable Ar8+ ions with H-2 have been studied by using X-VUV and Auger spectroscopy at 10 keV per charge.

Amnesia leaves some memory abilities completely intact and others only partially so. Although these dissociations have been interpreted as evidence for separate memory systems, McClelland and Rumelhart (1986) suggest that a simple decrease in the learning rate might account for a dissociation between the retention of category and exemplar information. The present experiment was carried ow to determine whether memory abilities involved in the formation of artificial categories are preserved in amnesia, and whether the results would be compatible with McClelland and Rumelhart's proposal. It turned out that performance was partially preserved and the pattern of results matched what could be predicted from the categorization literature. Although more typical transfer stimuli were classified better by both normal and amnesic subjects, this typicality gradient disappeared within about 24 hours in amnesic patients. However, only normal subjects classified old (previously presented) exemplars better than new exemplars. These results are compatible with McClelland and Rumelhart's suggestion. The continuous degradation of exemplar traces may be responsible for the loss of exemplar information and the decline of the typicality gradient at different rates. The same would be true for the typicality gradient. These results are not easily explained by a multiple memory system, but fit reasonably well into Jacoby's (1991) multi-process approach.

Amnesic patients and control subjects were asked to reproduce arm movements of a given amplitude and to average amplitudes on series of three such movements. The error in averaging was found to be equal in patients and control subjects while reproduction performance was clearly affected by amnesia. The implications of these data for a theory of amnesia are briefly discussed.
