, 2020 During the past decades, central banks acquired considerable independence from democratic institutions under the Central Bank Independence (CBI) template. Yet, the changing role of central banks since the 2007–2008 crisis has led to a (re)politicization of central banking and has weakened the scientific and political consensus on the CBI model. In turn,

The Characterization of Generalized Jordan Centralizers on Triangular Algebras
Journal of Function Spaces, 2018 In this paper, it is shown that if T=Tri(A,M,B) is a triangular algebra and ϕ is an additive operator on T such that (m+n+k+l)ϕ(T2)-(mϕ(T)T+nTϕ(T)+kϕ(I)T2+lT2ϕ(I))∈FI for any T∈T, then ϕ is a centralizer. It follows that an (m,n)- Jordan centralizer on a

THE LAYOUT OF DRILLING STRING FOR IMPLEMENTATION OF THE PROFILE BUILD-AND-HOLE WELLBORE
Известия высших учебных заведений: Нефть и газ, 2018 When drilling deep oil and gas wells with large deviations from the vertical stope the resistance when moving the drill string in borehole significantly increases. A consequence of this is the difficulty of control screw steerable motor.

Centralizer and liftable centralizer of special flows over rotations
, 2017 The liftable centralizer for special flows over irrational rotations is studied. It is shown that there are such flows under piecewise constant roof functions which are rigid and whose liftable centralizer is ...

Improving the Efficiency of Curved Wells’ Operation by Means of Progressive Cavity Pumps
Energies, 2022 This paper proposes a solution to the problem of improving the reliability of the operation of progressive cavity pump units in deviated and directional wells. High dogleg severity significantly contributes to rod breakage; rods often break close to the “

On Groups with Extreme Centralizers and Normalizers [PDF]
Advances in Group Theory and Applications, 2016 An FCI-group is a group in which every non-normal cyclic subgroup has finite index in its centralizer and an FNI-group is one in which every non-normal subgroup has finite index in its normalizer.

Complete parts and subhypergroups in reversible regular hypergroups
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022 In this paper we analyse the center and centralizer of an element in the context of reversible regular hypergroups, in order to obtain the class equation in regular reversible hypergroups, by using complete parts.

Indian Journal of Endocrinology and Metabolism, 2011 Central hypothyroidism is defined as hypothyroidism due to insufficient stimulation by thyroid stimulating hormone (TSH) of an otherwise normal thyroid gland. It has an estimated prevalence of approximately 1 in 80,000 to 1 in 120,000. It can be secondary hypothyroidism (pituitary) or tertiary hypothyroidism (hypothalamus) in origin. In children, it is
