Factors and mechanisms of productive secondary reservoirs formation in deep-lying oil and gas complexes. Article 2. Carbonate minerals – lithogenetic and tectonophysical indicators of the secondary reservoirs conditions formation at large depths

Мінеральні ресурси України
Authigenic carbonate minerals, together with clayey matter, play a leading role in the cementation of terrigenous phaneromorphic (granular) rocks. Studying the regularities of carbonate authigenesis is of primary importance for oil and gas geology.

The Asymptotic Number of Attractors in the Random Map Model [PDF]

, 2002
The random map model is a deterministic dynamical system in a finite phase space with n points. The map that establishes the dynamics of the system is constructed by randomly choosing, for every point, another one as being its image.

Differential expression of conserved germ line markers and delayed segregation of male and female primordial germ cells in a hermaphrodite, the leech helobdella. [PDF]

, 2013
In sexually reproducing animals, primordial germ cells (PGCs) are often set aside early in embryogenesis, a strategy that minimizes the risk of genomic damage associated with replication and mitosis during the cell cycle.

Developmental Systems Theory as a Process Theory [PDF]

, 2018
Griffiths and Russell D. Gray (1994, 1997, 2001) have argued that the fundamental unit of analysis in developmental systems theory should be a process – the life cycle – and not a set of developmental resources and interactions between those resources ...
