Shang Ritual Bronzes: Casting Technique and Vessel Design

Structural and compositional analysis of a casting mold sherd from ancient China

Casting had symbolic significance and was strictly controlled in the Shang dynasty of ancient China. Vessel casting was mainly distributed around the Shang capital, Yin Ruins, which indicates a rigorous centralization of authority. Thus, for a casting mold to be excavated far from the capital region is rare. In addition to some bronze vessel molds excavated at the Buyao Village site, another ke...

    Below knee amputation, which is noticed as one of the most common lower extremity amputations, is caused as a result of various factors like trauma, disease, or congenital limb deficiencies. In order to take these amputees back to daily life, below knee prostheses are used as an alternate to original limb. Comfort and patients’ satisfaction with prostheses are directly related to each prost...

Tonsillar Disease and Capillary Vessels

The three-dimensional structure of capillary vessels in the human palatine tonsil using corrosion casting technique was investigated. The postcapillary venules and arterioles were distinguishable from the nuclear impressions on their walls. The configuration of vessels around cryptal micropores is similar to images obtained by a recently developed cryptscope. The palatine tonsil has no efferent...

Cell-Based First-Hit Ray Casting

Cell-based first-hit ray casting is a new technique for fast perspective volume visualization. This technique, based on the well known ray casting algorithm, performs iso-surfacing and supports interactive threshold adjustment. It is accelerated by the reduction of average ray path lengths to only a few steps per pixel. The volume is divided into cubic sub volumes. Each sub volume that is inter...
