Practical Simulation of Magnetic Field of Permanent Magnets System to Explore Size of Magnetic Nanoparticles

We present the approach for computer simulation of magnetic field in a gap between two cylindrical permanent magnets connected by a yoke using FlexPDE software. Proposed approach shows that this implementation allows using program code written "almost natural mathematical language" for successful simulation in practical goals of physical experiments. Particularly, the provided program code and idea of introduction of an effective backsides curvature of magnets have been used in the series of acoustomagnetic studies, i.e. this publication serves also as an example of "reproducible calculations" ideology providing all actual computational details and code.

Analysis of technogenic impact (gas-industrial complex) on the state of soil and groundwater

The results of experimental studies of soil properties in area that was contaminated following the disaster at drilling of the gas-bearing-well at oil and gas production facility are represented. The local population uses this soil for agricultural purposes. Conclusions on the impact of emergency on the state of soil, natural and drinking water of decentralized water supply to nearby settlements are made

Old Belief monasteries of the «Yenisei meridian» in the 20th century: origins, traditions and current state

The article analyzes the role of Old Belief monasteries in the rise of a universal confessional space of contemporary Chasovennye («chapel-goers» or “chapel people”, a non-priestly faction among Old Believers) in the Krasnoyarsk oblast and Tuva. Also explored are the trends and motives of their migration routes, peculiarities of the  religious life within their communities and the structure of Old Belief monasteries as religious and economic centers. The source base of the study includes  eyewitnesses’ recollections and testimonies from other informants, as well as documents from the state archive of the Republic of Tuva. The article is complemented with a brief review of the settlement of Old Believers throughout southern Siberia in the 20th century. The traditions of spiritual and economic life in Old Belief monasteries along the Yenisei in the 20th century receive special treatment. The confessional space of the Сhasovennye knows no other boundaries than the sacred. The Сouncil (sobor) appears where the community’s “own” people are, such as relatives or co-religionists. Despite the seeming fragmentation and remoteness of their settlements, the ties between them never break. Dubches monasteries never ceased to be spiritual centers for both its immediate neighborhood and the whole community of the Chasovennye in the world, including Tuva. The need for the community to preserve the common confessional space, the still-practiced joint discussion of the challenges of the time, the support for the purity of marriage ties and, as a consequence, the preservation of the family and the community in need of the monasteries as its ideological and spiritual centers — all of these hold out our hope in the future of the skete tradition and even, perhaps, in its revival in Tuva in the foreseeable future

Boson-Fermion pairing in a Boson-Fermion environment

Propagation of a Boson-Fermion (B-F) pair in a B-F environment is considered. The possibility of formation of stable strongly correlated B-F pairs, embedded in the continuum, is pointed out. The new Fermi gas of correlated B-F pairs shows a strongly modified Fermi surface. The interaction between like particles is neglected in this exploratory study. Various physical situations where our new pairing mechanism could be of importance are invoked.Comment: 8 pages, 8 figers, to be published in Phys. Rev.

Statics of Magnetic Fluid Drop with Compound Magnetic Core in a Wedge-Shaped Channel

A behavior of magnetic fluid drop with compound magnetic core in a wedge-shaped channel was studied experimentally. The study examines influence of magnetic fluid properties, its volume and magnetic field on statics of the system compound magnet – magnetic fluid drop in wedge-shaped channel. The possibility to change the static conditions of such system by altering magnetic field of the core was observed.

BARRIERS IN MUTUAL TRADE IN ELECTRIC ENERGY IN THE FRAMEWORK OF THE COMMON ELECTRIC POWER MARKET OF THE EURASIAN ECONOMIC UNION

The mutual trade in electricity between the Russian Federation and other members of the Eurasian Economic Union is considered. The existing barriers to the formation of the common electric power market of the Eurasian Economic Union have analysed. The possible variants of centralized electricity trading under fixedterm contracts and day ahead market have considered. Both positive and negative effects for the domestic electricity market have identified as the result of the formation of the common electric power market of the Eurasian Economic Union

Influence of Brownian Diffusion on Levitation of Bodies in Magnetic Fluid

The present work deals with experimental investigation of the levitation of magnetic and non-magnetic bodies in a magnetic fluid when essentially influenced by Brownian diffusion of magnetic particles in it. It is established that the point of levitation of bodies in a magnetic fluid varies with time.

Methods of monitoring the Ground-Climate-Pipeline system in sections with hazardous processes

The paper considers the concept of combining various means of monitoring of the Ground-Climate-Pipeline system sections exposed to hazardous processes. The concept of "hazardous processes"is described. Sensors selected for monitoring parameters in the Ground-Climate-Pipeline system are described. A monitoring scheme is proposed and described, all elements of which are functionally combined through information transfer networks. The advantages of using artificial intelligence in the proposed monitoring system are explained
