On the basis of T/S measurements water masses were differentiated and geostrophic currents were drawn. It was stated, that the Weddell Sea waters filled a major part of Bransfield Strait from the southeast to Trinity Island on the west. Waters originating from Bellingshausen Sea occurred in the western and northern part of the research area and along the southern coasts of Shetlands. The direction of the geostrophic current is from the southwest to the northeast with a branch in the south at the top of the Antarctic Peninsula.
The study was aimed to determine the hydrodynamic of water seepage through a porous bed saturated with different amounts of high viscosity liquids. An attempt was made to describe the process of seepage through beds saturated with oils using the theory of outflow of a liquid from the tank. It was assumed that the discharge coefficient will represent changes of flow resistance during the process. It was found that the dependence of this factor on time is linear. In the second part of this work kinetics of the seepage process was investigated. Dependence of oil concentrations, eluted from the deposit with the flowing water, on time has been evaluated. Thanks to these studies it was possible to determine the effectiveness of an elution of high viscosity liquids from porous beds using water as the washing out liquid.
The paper discusses a two-machine flow shop problem with minimization of the sum of tardiness costs, being a generalization of the popular NP-hard single-machine problem with this criterion. We propose the introduction of new elimination block properties allowing for accelerating the operation of approximate algorithms of local searches, solving this problem and improving the quality of solutions determined by them.
