Иркутские кварталы: Преамбула руководителя проекта

The project director Alexei Kozmin speaks about the key principals that were used in the project for the territory in the historical center of Irkutsk: multifunctionality, harmony with man, permeability, careful attitude to history, etc. Руководитель проекта Алексей Козьмин рассказывает об основных принципах, использованных при проектировании территории в историческом центре Иркутска – многофункциональности, соразмерности человеку, проницаемости, бережном отношении к истории и др.

Три концепции пространственного развития Иркутска

It is crucial for a present-day big city not to reduce the process of spatial planning to elaboration of a formal master plan and other town-planning documents. The spatial planning should flow from the city development strategy and be based on real economic projects and demographic potential. At the same time, strategic planning should include a spatial component, because implementation scenarios for strategic plans come from the condition of the territory, possibilities and limitations of urban space.Для современного большого города крайне важно, чтобы процесс пространственного планирования не сводился к разработке формального генерального плана и других градостроительных документов. Необходимо, чтобы пространственное планирование являлось продолжением стратегии городского развития, опиралось на реальные экономические проекты и демографический потенциал. В то же время и стратегическое планирование не может не включать в себя пространственную составляющую. Ведь из состояния территории, возможностей и ограничений городского пространства складываются и сценарии реализации стратегических планов

The Soil-Structure Interaction in Bridge Dynamics Problems

At the Bridges Department of Leningrad Institute of Railway Communication Engineers complex investigations of bridge dynamics under the seismic and rolling stock loads had been carried out. It is ascertained that for theoretical description of bridge oscillations the question of piers-base interaction is a matter of principal importance. During the process of oscillations there is a loss of energy due to the radiation by the propagation of elastic waves in the soil. These losses of energy considerably exceed the hysteresis ones, especially for bridges with metal span structures. Researches carried out allowed to make the theoretical estimation of the general factor of the span structure dynamics, to work out design technique for bridge piers and span structures under seismic loads (both according to the method of spectral analysis and with the use of the earthquake accelerograms), to predict the consequences of the local oscillations of bridge elements

Study of the Effect of Radiation Dose Rate on the Stability of Various Organochlorine Pesticides

Abstract irradiated at dose of 10 kGy with dose rate varied from 8.3 ⋅ 10−3 up to 2.33 Gy/sec. It is found that the shape of the degradation degree relationship on dose rate is similar for different OCPs in polar and non-polar solvents (hexane, 2-propanol) and does not depend on the concentration of initial substance. The maximum of the OCP degradation degree is registered in the dose rate range of 0.23-0.43 Gy/sec. A lognormal distribution is considered as a function best fitting the experimental data. The OCP degradation mechanism could be explained by the ratio of active and recombined particles along the gradient of ionizing radiation intensity.
