At the level of this formation, the geological research conducted in four localities near the Prut Valley demonstrated, based on two new foraminifera genera identified in this area--Oolina and Velapertina-favorable conditions for the development of the stenohaline fauna, a marine shelf environment with warm water, as well as the certitude regarding the age of the late Badenian for these. These results were not previously reported in this area.展开更多

The model has two RC networks characterizing battery activation and concentration polarization process. The parameters of the model are identified using combined experimental and extended Kalman filter (EKF) recursive methods. The open-circuit voltage and ohmic resistance of the battery are directly measured and calculated from experimental measurements, respectively. The rest of the coupled dynamic parameters, i.e. the RC network parameters, are estimated using the EKF method. Experimental and simulation results are presented to demonstrate the efficacy of the proposed circuit model and parameter identification techniques for simulating battery dynamics.展开更多

Thirty-two diseased and 22 vibriocarriers were found on the territory of the city in the course of epidemic. The potential sources of infection are specified. The ways to avoid similar situations in the future are suggested. The analysis of the locations of the cholera contamination sources results in the obvious conclusion that most of them are connected with the place where the river Kalmius meets the Azov Sea. Waste flow from the residential solid waste landfill brings a considerable harm to the river Kalmius and the Azov Sea.展开更多
