Abstract Effective separation of water and oil dispersions is considered a critical step in the determination of technical and economic success in the petroleum industry over the years. Moreover, a deeper understanding of the emulsification process and different affected parameters is essential for cost-effective oil production, transportation, and downstream processing. Numerous studies conducted on the concept of dispersion characterization indicate the importance of this concept, which deserves attention by the scientific community. Therefore, a comprehensive review study with critical analysis on significant concepts will help readers follow them easily. This study is a comprehensive review of the concept of dispersion characterization and conducted studies recently published. The main purposes of this review are to 1) Highlight flaws, 2) Outline gaps and weaknesses, 3) Address conflicts, 4) Prevent duplication of effort, 5) List factors affecting dispersion. It was found that the separation efficiency and stability of dispersions are affected by different chemical and physical factors. Factors affecting the stability of the emulsions have been studied in detail and will help to look for the right action to ensure stable emulsions. In addition, methods of ensuring stability, especially coalescence are highlighted, and coalescence mathematical explanations of phenomena are presented.

Open Issues

The protein folded state is the result of the fine balance of a variety of different forces. Even minor structural perturbations may have a significant impact on the stability of these macromolecules. Studies carried out in recent decades have led to the convergent view that proteins are endowed with a flexible spine. One of the open issues related to protein local backbone geometry is the identification of the factors that influence the amplitude of the τ (N—Cα—C) angle. Here, statistical analyses performed on an updated ensemble of X-ray protein structures by dissecting the contribution of the major factors that can potentially influence the local backbone geometry of proteins are reported. The data clearly indicate that the local backbone conformation has a prominent impact on the modulation of the τ angle. Therefore, a proper assessment of the impact of the other potential factors can only be appropriately evaluated when small (φ, ψ) regions are considered. Here, it is shown that when the contribution of the backbone conformation is removed by considering small (φ, ψ) areas, an impact of secondary structure, as defined byDSSP, and/or the residue type on τ is still detectable, although to a limited extent. Indeed, distinct τ-value distributions are detected for Pro/Gly and β-branched (Ile/Val) residues. The key role of the local backbone conformation highlighted here supports the use of variable local backbone geometry in protein refinement protocols.

The Stability

Ion transport–driven instabilities in electrodeposition of metals that lead to morphological instabilities and dendrites are receiving renewed attention because mitigation strategies are needed for improving rechargeability and safety of lithium batteries. The growth rate of these morphological instabilities can be slowed by immobilizing a fraction of anions within the electrolyte to reduce the electric field at the metal electrode. We analyze the role of elastic deformation of the solid electrolyte with immobilized anions and present theory combining the roles of separator elasticity and modified transport to evaluate the factors affecting the stability of planar deposition over a wide range of current densities. We find that stable electrodeposition can be easily achieved even at relatively high current densities in electrolytes/separators with moderate polymer-like mechanical moduli, provided a small fraction of anions are immobilized in the separator.

The purpose of this paper is to improve the analysis of the financial stability of enterprises and to identify the key factors affecting the establishment of the sustainable growth trend of enterprises (except the financial sector) in Georgia. Answering the question: what financial challenges do enterprises in Georgia face today and be designed consequently, recommendations for strengthening the financial stability of enterprises should be developed in Georgia, increasing solvency and mitigating bankruptcy risks? The necessity for the financial stability of enterprises is becoming increasingly important both for sustainable business growth and for the stability of the international financial market.The subject of the study is the financial positions and financial results of the analytical enterprises. The first and second categories of joint-stock companies of Georgia and limited liability companies were selected as the research objects. Ten enterprises in total. The research methodology includes methods of economic and statistical analysis, factor analysis, vertical, horizontal, proportional and ratio analysis.In order to improve financial management and control, the paper presents multi-factor models of several indicators created by the author. These are: the tree-factor model the coefficient of the organic structure of capital, an eight-factor model of profitability and a six-factor model of the Financial leverage. The paper conducts practical research on the example of ten Georgian companies and concludes that the main challenges in today›s Georgia are the dangers of losing financial stability and bankruptcy. The reason for such a tense financial situation is not a «Corona-19». According to the author, the main reasons for the instability of enterprises in Georgia are: The Irresponsibility of business owners and management, low management professionalism and hidden flows of cash resources.
