On lacunary statistical convergence of double sequences and some properties in fuzzy normed spaces
(Journal of Intelligent Fuzzy Systems, 2019)
In this study, we have investigated the concepts of lacunary summable, lacunary statistical convergence and lacunary statistically Cauchy sequence for double sequences in fuzzy normed spaces. Also, we have investigated ...
Effects of H2S and CO2 on Cement/Casing interface corrosion integrity for cold climate oil and gas well applications
(The Electrochemical Society, 2016)
Low-temperature corrosion relevant to oil and gas wells was investigated. Casing cement was exposed to brine in contact with CO2 at 4 °C and 10 MPa. Pore water was extracted from wet cement using a die press, and a cement ...
On the fine spectrum of the upper triangle double band matrix Δ+ on the sequence space c0
(2013)
In this study, we determine the fine spectrum of the matrix operator ∆+ defined by an upper triangle double band matrix acting on the sequence space c_0 with respect to the Goldberg’s classification. As a new development, ...
The effect of polypyrrole and nickel + polypyrrole coatings on corrosion behaviour AISI 304 stainless steel
(Pleiades Publishing, Ltd, 2015)
Polypyrrole (PPy) and nickel + PPy (Ni + PPy) coatings have been occured on AISI 304 stainless steel (304 SS) surface by cyclic voltammetry technique in aqueous oxalic acid solutions and as the supporting electrolytes was ...
Corrosion of 13Cr steel at the Cement/Casing interface in CO2/H2S environments at 4, 85 and 200 °C
(Nace International, 2018)
A study was carried out to investigate corrosion at the cement/casing interface for 13Cr casing steel. Cement simulated pore solution (CSPS) was developed by exposing cement pieces to 5% NaCl at 100 °C and 10 MPa in ...
Lacunary statistical convergence of double sequences of sets
(2016)
In this paper, we study the concepts of Wijsman statistical convergence, Wijsman lacunary statistical convergence, Wijsman lacunary convergence and Wijsman strongly lacunary convergence double sequences of sets and investigate ...
On statistical convergence of double sequences of closed sets
(JSTOR, 2016)
In this paper, we introduce the concepts of statistical inner and statistical outer limits for double
sequences of closed sets and give some formulas for finding these limits. Also, we give the Kuratowski
statistical ...
On rough convergence in 2-Normed spaces and some properties
(2019)
In this study, we investigated relationships between rough convergence and classical convergence and studied some properties about the notion of rough convergence, the set of rough limit points and rough cluster points of ...
The use of papaver somniferum L. Plant extract as corrosion inhibitor
(Pleiades Publishing, Ltd, 2019)
The corrosion inhibition and adsorption characteristics of the extract obtained from the plant Papaver somniferum L. (PSL) by electrochemical methods at different temperatures (25, 35 and 45°C) were investigated in 0.2 M ...
The examination of Afyonkarahisar's geothermal system corrosion
(ASM International, 2013)
Corrosion and scaling of metal surfaces are the major problems caused by geothermal fluids when metallic structures are used. This article describes a study of corrosion and scaling problems in the Afyonkarahisar Geothermal ...
