New method of preoperative selection of patients with gastro-oesophageal reflux disease
(Termedia Publishing, 2019-09-30)
Introduction: The identification of sliding hiatal hernia (SHH) less than 3 cm in size using barium swallow fluoroscopy (BSF) and oesophagogastroduodenoscopy (OGD) was recently noted as a non-reliable method, allowing for ...
О разрешимости конечной группы с полунормальными или субнормальными подгруппами Шмидта некоторой ее максимальной подгруппы
(2019)
Группой Шмидта называют конечную ненильпотентную группу, все собственные подгруппы которой нильпотентны. Группа с нильпотентной максимальной подгруппой, как известно, является разрешимой, если коммутант силовской 2-подгруппы ...
Evolution of Structure and Magnetic Properties in EuxBi1-xFeO3 Multiferroics Obtained under High Pressure
(Elsevier B.V, 2019-05-29)
The structure, microstructure, magnetic properties and magnetocaloric effect in the BiFeO3-based multiferroics
with a partial isovalent substitution of bismuth for europium ions have been experimentally and theoretically ...
Structure, Non-stoichiometry, Valence of Ions, Dielectric and Magnetic Properties of Single-Phase Bi0.9La0.1FeO3-δ Multiferroics
(Elsevier B.V, 2019-03-21)
The structure, microstructure, valence states, non-stoichiometry, dielectric and magnetic properties of
lanthanum-modified multiferroics have been studied by X-ray diffraction, thermogravimetric, iodometric
titration, ...
Liquid-phase sintered bismuth ferrite multiferroics and their giant dielectric constant
(Elsevier B.V, 2019-04-28)
Rapid liquid-phase sintering method has been modified and used to synthesize Bi1-xLaxFeO3-δ compositions
(0 ≤ x ≤ 0.5). The temperature and sintering procedures to obtain stable single-phase samples have been de-
fined. ...
Predicted model of magnetocaloric effect in BiFeO3-based multiferroics.
(Elsevier B.V, 2019-06-20)
Structure, magnetic properties and magnetocaloric effect in synthesized Bi-based multiferroics with a partial
isovalent substitution of bismuth (III) cations for rare-earth elements (R = La, Nd, Sm, Eu, Gd, Dy, Er) have ...
An attempt to correlate the physical properties of fossil and subfossil resins with their age and geographic location
(2019)
Testing of the correlation between physical properties of natural resins such as microhardness, density and UV-excited fluorescence emission with their age, geological conditions, botanical and geographical origin and ...
Finite groups with two supersoluble subgroups
(de Gruyter, 2019)
Let G be a finite group. In this paper we obtain some sufficient conditions
for the supersolubility of G with two supersoluble non-conjugate subgroups H and K of
prime index, not necessarily distinct. It is established ...
