A side effect is minimal, including secondary mineral formation, selective dissolution of mineral systems constituting the rock structure, etc.
The Prisklonovoye field, discovered in 1986 by testing the BP121 formation in well 58 within the Severo-Gubkinskaya area, belongs to the local structure of IV order (the Severo-Purpeysky local elevation) that complicates the Purpeysky large brachy-anticline located in the central part of the order II structure – the Purpeysky small swell.
The structure of sand stones is aleuritic psammitic, and that of siltstones is psammitic aleuritic.
One of the main lithologic factors forming the porous space structure of BP12 horizon reservoir units is sedimentary one.
Laboratory studies have been conducted in the oilfield chemistry R&D center of the Tyumen State University headed by the Candidate of Engineering Sciences V.V.

Hence, this interface structure provided the minimum energy value and was used for this study.
For all structures, electronic degrees of freedom were converged to 10-6 eV/cell.
In the first step, we relaxed the interface structure.

Generally it was connected as with different low melting point of Al (660oC) and Ga (30oC) as with the velocity of phase transformation and proceeding reaction through the intermetallics but intermediate ternary oxide structures.
Phase fine structure and magnetic properties of obtained composites have been studied.
In addition the doublet belonging to wustite (Fe 1-X O) structure appears.
In the case of α-Fe2O3 + Ga powder mixture grinding with Fe addition the similar results (Fig.1 (f)) with partial destruction of α-Fe2O3 and significant Fe-Ga intermetallics also as wustite structure formation were observed.

This demand can be met by integrating a printed double layer capacitor into the cell structure.
The authors of this paper have published the structure and electrical properties of printed supercapacitors using various watery electrolytes [9].
The structure of this component is schematically shown in figure 2.
The capacitor structure is otherwise similar to the one presented in figure 3.
The supercapacitor structures have been designed to give adequate power pulses for an RFID application.

Figure 1 Chemical structure of polyisoprene (PI).
The chemical structure of PI is shown in Fig. 1.

Fuller developed structures that postulate the possibility of unknown elements [7].
Architects seek to create structures that meet a functional purpose and expressing their vision or their community culture: the Coliseum of Rome, the Empire State Building of New York, and the Pompidou Centre of Paris; each an example of combination the technical and aesthetic.
In every case, the form of the building has been powerfully influenced by the nature of the materials of which its structure is made.
a, b: The forms of these structures are directed by the brittleness of the stone, making it strong in compression but weaker in tension and bending.

Introduction Underground metal structures are usually expected to have a long working life, often 50 to 100 years.
Structures such as natural gas, crude oil pipelines and water mains are only some of the many structures reported to have been affected by soil corrosion around the world [1-3].
The structure of corrosion products were analyzed by X-ray diffraction(XRD).
It is seen that the microstructure of as-received steel (Fig.1a) is a uniform acicular ferrite(AF) structure which consist of granular bainite (GB), polygonal ferrite(PF) and a small amount of pearlite (Fig.1a)[13].

No evidence of carbon coating is shown in XRD peaks, which might be due to either its amorphous structure or the fact that carbon coating on LiMnPO4 particles is too thin.
Transmission electron microscopic studies were performed on the samples to further understand the morphology and structure of synthesized LiCu0.05Mn0.95PO4/C.
The corresponding SAED pattern in Fig. 3c taken from an individual LiCu0.05Mn0.95PO4/C nanorod, in which the spots with strong intensity could be indexed to an olivine structure of the sample.
Cu doping did not substantially influence the structure of LiMnPO4.

Patterns of X-ray diffraction showed the characteristic peaks of the structure of mordenite.
After incorporation with molybdenum oxide, the structure of mordenite zeolite was preserved.
After impregnation the analyses performed by EDX revelead that a 0.84% MoO3 was effectivelly incorpo- rated in the Mordenite (MOR) structure.
Conclusions After incorporation with molybdenum oxide, the structure of mordenite zeolite was preserved.
