Flies move their eyes by turning their heads either spontaneously or in response to unexpected disturbances of their preferred flight attitude. They use several visual and mechanosensory cues to keep flight balance and to stabilize their eyes relative to the surroundings by compensatory head/eye movements. The various sensory subsystems have different speed characteristics and cooperate autonom...
متن کاملMedical Education in Ancient Persia
Introduction: Historically, education is the prominent part of medical systems of different cultures. It has been surveyed in some cultures. In this study, we tried to uncover educational practices applied and present a sketch of medical education in ancient Persia (from beginning to 637 AD) based on the available evidence. Methods: In this study, old Persian scripts and other written document...

In continuous casting of steel, the interfacial gap between the mold and the solidifying shell controls heat transfer in the process and is responsible for lubrication and the prevention of cracks and other defects. Mold slag forms when mold powder added to the top surface of the steel melts, and is the best current practice to perform these important functions. The properties and behavior of t...

In the conventional continuous casting of steel, either mold powder or oil can be added to lubricate the mold from sticking to the solidifying steel shell. The mold powder melts to form a molten slag or flux layer, and also acts to protect the molten steel from oxidation, to insulate the molten steel from heat loss, to absorb inclusions from the molten steel, to regulate heat transfer to mold w...

Fluid mixing assumes an important role in various processing industries, in which the chemical efficiencies of typical processing operations carried out are intrinsically related to their hydrodynamic performance. In order to achieve high product qualities in steelmaking, submerged gas injection in ladles has now become a widely accepted industrial practice in almost every steelmaking shop. The...
