**Gas** infrastructure development in the countries of East Baltic as a way to increase energy security

In the context of regional **gas** infrastructure development this paper considers the issue of energy security of the countries of East Baltic, which depend heavily on a single energy supplier — Russia. In recent years, the countries of the region have announced several LNG terminal ...

#### The Flow of **Gas** with Dispersed Particles in a Cylindrical Channel at a Subsonic Speed

In this article, we present a method and an algorithm for calculating the dynamic characteristics of **gas** flow in a cylindrical channel at a subsonic speed, in the presence of dispersed particles in the **gas**. The problem of identifying the dynamic characteristics of dispersed particle- containing inert **gas** feed into ladles and the converter is used to ...

#### Research and technology agreements in the Norwegian concession system of the 1970s—1990s

This article is devoted to research and technology agreements in Norway, and their positive impact on the development of relations with foreign oil and **gas** companies during the period of formation of the Norwegian oil and **gas** industry. Based on archival documents, the article considers Norway’s experience of conclusion of research and technology agreements for transferring the latest technologies of ...

#### The flow of **gas** in a cylindrical channel at a subsonic speed

The article gives the account of steady flow of a perfect **gas** in a vertical channel having some other parameters set. The flow is supposed to be highspeed, subsonic and design, that is the **gas** pressure at the outlet equal to the pressure (back pressure), while the forces of gravity can be neglected. The boundary ...

#### The species composition and the biotopical groups of the gastropoda in the pond of Kaliningrad

This article considers the species composition, species biotopic distribution, nutrition, and zoogeographic characteristics of gastropoda in Kaliningrad ponds. The author shows the interplay of ecological factors that determine the species composition of molluscs. The article also presents the data on the impact of the invasive species Potamopyrgus antipodarum (Gray, 1843) on the malacofauna of water bodies. 1. Аристова Г . И . Бентос Куршского и Вислинского...

#### Economic and geopolitical aspects of the Nord Stream 2 **gas** pipeline

The Nord Stream 2 **gas** pipeline project (NS 2) along the bottom of the Baltic Sea is aimed to increase **gas** supply from Russia to Germany and other EU countries. It serves mutual economic interests: the predicted growth in **gas** demand in the EU markets and the need to strengthen ...

#### Mathematical model of transportation of relativistic electronic beams. Analogy to the equations of **gas** dynamics

Analytical comparison of hyperbolic system consists of four equations for moments of the distribution function of relativistic electron beam (REB), the modeling transportation processes in the **gas** environment and the equations of **gas** dynamics of ideal polytropic **gas** was carried out. The found analogy between these models allowed to specify mathematical statement of a problem for REB and to facilitate a choice of edge conditions of the task....

#### Basic thermodynamic parameters in a non-ideal **gas** and the speed of sound based on various equations of state

The paper derives explicit relations for thermodynamic quantities and the adiabatic equation for a **gas** described by the equation of state of the most general form. Explicit formulas are given for the most known equations of state. As an example, the nature of the behavior of the speed of sound as a function of temperature and pressure for the Van der ...

#### Power rating of flares power burning associated **gas** by processing satellite images MODIS

Described modified method for estimating flares power of burning associated **gas** by processing satellite images MODIS. The program complex estimates associated flared **gas** volume for a given torch unit and licensed areas within the selected calendar periods. The methodology and software system tested for the most powerful oil fields ...

#### Features of modeling turbulent **gas** flows with evaporating droplets

The features of modeling **gas** flows with evaporating droplets are considered. Such flows are found in power plants and technological devices. The resistance curve for a drop with corrections for quasi-stationary motion, the dependence of the correction coefficient on the ...

#### Treatment of peptic ulcer of gastroenteroanastomosis complicated by ongoing bleeding. Practical observation

The article describes a clinical case of surgical treatment of postgastroresection syndrome, represented by a peptic ulcer of gastroenteroanastomosis, ulcerative bleeding and a shortened (insufficient length) adductor loop. Complications wereseen to have resulted from insufficient volume of gastric resection, while a small length of the adductor loop created certain difficulties for reconstructive surgery. We performed an adequate resection of the organ stump and found a solution to the problem...

#### The Functional and the Instrumental in Market Definition: a Laboratory for Natural Experiments in the Baltics

... efficient solution is the organisation of interactions within a group of legal entities in control (within a single economic entity). In order to compare the practical implementation of institutional alternatives, we examine the modes of governance in the **gas** supply industry. A major focus is the Baltic region where two interconnected pipelines — the Nord Stream and the OPAL — were constructed. Different ways to handle transactions relating to **gas** supply were employed at the time. We compare these ...

#### Program realization of calculation method of radio signal attenuation in atmospheric gases for satellite communications

The authors study the application of calculation method of radio signal attenuation in atmospheric gases, proposed by International Telecommunication Union [1]. The paper describes the algorithm of attenuation calculation, created in MATLAB program and calculated resulting attenuation for latitudes are greater than 45°. 1.

#### The goecological seismic risk associated with the construction of an underground **gas** storage in the Kaliningrad region

This article justifies the methodology for assessing the geoecological seismic risk associated with the construction of the Kaliningrad Underground **Gas** Storage (KUGS). A modified Leopold matrix helped obtain semi-quantitative seismic safety estimate for the object under consideration. The risk assessment is taken into account when developing technological solutions at the design stage.

#### Thermal calculation of the anode of the stationary plasma engine

The paper includes the thermal calculation of the anode **gas** distributor in Stationary Plasma Thruster (SPT) discharge system made with SolidWorks Software, that allows to determine with sufficient accuracy the model’s sensibility vs. variation of the different parameters. The calculation can define the minimum ...

#### The fractured reservoir of the Riphean of the Angara folds zone

This article gives an overview of the Low Angara oil-and-gas basin. The prospectively of the upper Riphean sediments of Angara folds is shown. The authors present the results of a forecast of fractured reservoir propagation in the top layer of Riphean sediments in the case of the Ilbokich license area. The article analyses scattered waves and identifies the objects interpreted as frac-tured reservoir propagation areas. 1. Кремлев А. Н., Ерохин Г. Н., Стариков Л. Е. и...
