Seismic Safety of Large Vertical Steel Cylindrical TanksGrounds
Abstract
The objectives of this paper are to highlight the principal effects of base uplifting on the seismic response of ground supported cylindrical steel tanks that are unanchored at their Base. Specific areas targeted for improvements are related to: a) Estimation of the loads exerted on anchored tanks, particularly the overturning moment, b) Estimation of the compressive stress and allowable shell buckling stress at the shell bottom.

The Study of Oil Field Well Using GDIS-Method to Unsteady Fluid Injection in a Porous Medium- a Method of Restoring the Bottom hole Pressure
Abstract
Well testing method to the removal of bottom-hole pressure recovery curve P (t) is one of the most important methods of field research wells and reservoirs in the study of the characteristics of productive oil fields during the entire history of their development. In this paper we have developed new methodological framework, significantly extending the reliable assessment of the basic hydrodynamic parameters and filtration systems drained reservoir deposits.

Improvement of Ecological Parameters of the Automobile Engine with Spark Ignition in Period Heating After Cold Start-Up
Abstract
This article about problems of reduction of emissions of harmful substances in the period automobile engines with spark ignition after cold start-up. In this period owing to low temperatures there is an incomplete combustion of fuel, and efficiency catalytic the converter is low. In article is considered the method of increase of efficiency heating of the engine and converter is considered by application of active chemical products of thermal decomposition of gasoline.

About a Hydrogen Role as Chemical Reagent in the Kinetic Mechanism of Carbonformation in A Diesel Engine
Abstract
Here is discussed the actual problem of modern engine engineering, namely reduction of soot particles emissions in diesel engines. One of the most effective methods of particles emission reduction, which is on based on hydrogen addition to a working body of diesel is considered here. A number of methodically well-founded positions about a hydrogen role as chemical reagent has been suggested in certificates of formation and the soot combustion which reliability is confirmed by results of natural experiment on diesel.
