“…The sonographic appearance of the small bowel depends on the degree of distension. The bowel may be collapsed, containing only a small amount of mucus, or it may be distended, containing fluid or gas 7 . Proper identification of the jejunum and ileum is difficult because of the lack of a fixed landmark, but it is possible by using topographic criteria, the frequency of valvulae conniventes, and activities of peristalsis.…”

Sonographic evaluation of the gastrointestinal (GI) tract may be difficult because of overlying intraluminal bowel gas and gas-related artifacts. However, in the absence of these factors and with the development of high-resolution scanners and the technical experience of radiologists, sonography can become a powerful tool for GI tract assessment. This pictorial essay focuses on sonographic findings of GI tract lesions compared with endoscopic, computed tomographic, and magnetic resonance imaging findings. Neoplastic and non-neoplastic diseases and postoperative complications are illustrated, and the distinctive sonographic characteristics of these entities are highlighted.

“…Based on the foregoing, it is assumed that the raceway stability is greatly susceptible to the flux of coke that flows into the raceway, that is, the heat flow ratio at tuyere. 20) Consequently, it is assumed that under all coke operation with a high heat flow ratio at tuyere and under intensive PC injection with a low heat flow ratio at tuyere, factors that define the raceway stability would differ.…”

Analyses on Dynamic Solid Flow in Blast Furnace Lower Part by Deadman Shape and Raceway Depth Measurement

As one of the factors of frequent troubles that occur in the transition period from all-coke operation to PC injection operation in blast furnace as well as increased troubles in recent years, increased size of the blast furnace and high-productivity operation are pointed out. Consequently, great importance is attached to burden distribution control and burden descent condition, or control of melting zone, deadman shape, solid flow at the lower part of furnace and others. In the present study, the reduced stockline surface profile was measured by the reflection intensity of microwave struck from the furnace top after blow-off with stockline reduced, and investigation was made on the countermeasures for changes in the raceway depth and furnace body profile during operation. As a result, it has been clarified that flow-down of coke into the lower part of blast furnace and inflow into the raceway are greatly subject to the existence of deadman which is the packed structure of the lower part of furnace, and further, they are closely related to dynamic behavior of the raceway and affect changes of the furnace body profile.

“…In contrast to the United States, sonography is used as the first‐line imaging modality in some European countries 14 , 15 and most developing countries 16 . With the recent technological advances of the sonographic machines that are available today, the ever‐improving resolution, and the ability to visualize the various characteristics of echo architecture that accompany spreading transmural inflammation, sonography is emerging as a premier modality for the imaging of the gastrointestinal tract 13 …”
