The invention relates to a real-world simulation device suitable for being installed in a computer designed to support a multitask programming environment (23). The device comprises a simulation manager (30), capable of working in asynchronous chaotic mode by repetitive sequences (31) on distinct simulation elements (40-70). Each simulation element works with at least one space/time datum, termed the structure point. A space/time datum includes a property datum, defining a current state of the structure point, and designates a function, applicable for modifying this current state. Said simulation manager (30) comprises two coupled simulation sections, namely a first and a second section, that are designed to simulate respectively a fluid medium and a solid body in the presence of said fluid medium. The manager (30) maintains a general periodicity of activation of the simulation elements which differs according to the physical phenomena simulated, in either of the two simulation sections

Substituted .omega.-nitroacetophenones and their preparation and intermediates therefor are described together with pharmaceutical compositions containing such nitroacetophenones for the prophylaxis and treatment of diseases associated with allergic or immunological reactions such as asthma, hayfever and rhinitis.
摘要:
A bucket using a box-like parallel-sided basket open at the front for dredging the sea bottom to collect nodules. The basket has a bottom wall with front and rear cross-bars and a plurality of parallel spaced rods extending longitudinally of the basket between the front and rear cross-bars. A front part of the bottom wall includes a grill formed by a transverse front link supporting one end of a plurality of longitudinal spaced flexible elements which are inclined downwardly towards the front and stretched between the front cross-bar and the transverse front link. Large shoes are positioned on lateral sides of the basket for supporting the bucket on the sea bottom. The grill is situated between the shoes with the transverse front link positioned in such manner that it penetrates the sea bottom. The basket is positioned inside the shoes and extends to the external edges of the shoes. The shoes include brackets for connecting a dredging line to the bucket.
