This study is defined within the context of the critical posthuman project of decentring humanist subjectivity. We argue that because agential realism, and the agency and performativity that go with it, do not enable non-human matter to be accountable, only human matter, in its intra-active becoming with non-human matter, can support an ethical project. Secondly, we map our understanding of Barad's agential realism, explaining the importance of agential cuts in phenomena-in-their-becoming that are the world worlding itself, and evaluate ethics, agency, and performativity in this material-discursive framework. Thirdly, understanding the material-discursive to underpin storied matter, we engage it via some clarification of narrative, and narrative agency. We conclude that much organic or inorganic nature as non-human matter is directional and responsive, so alive and generative and, in this sense, capable of worlding itself. However, it does not tell its own stories in the process. [ABSTRACT FROM AUTHOR]

In this article, we discuss the existence of solution for the functional integral equations in the Banach space BC(R+) of real-valued continuous and bounded functions, using the method associated with the technique of measure of noncompactness and generalized Darbo fixed point theorem. We provide an example to illustrate our results, and we make an iterative algorithm by the Sinc interpolation to find solution to the above problem with acceptable accuracy. [ABSTRACT FROM AUTHOR]

Best proximity results for cyclic and noncyclic F G -contractive operators in (strictly convex) Banach spaces are obtained via the measure of noncompactness. The work extends some of recent investigations in this direction. The obtained results are applied to investigation of optimum solutions for a system of second order differential equations with two initial conditions followed by an example. [ABSTRACT FROM AUTHOR]

We investigate the solutions of functional-integral equation of fractional order in the setting of a measure of noncompactness on real-valued bounded and continuous Banach space. We introduce a new μ-set contraction operator and derive generalized Darbo fixed point results using an arbitrary measure of noncompactness in Banach spaces. An illustration is given in support of the solution of a functional-integral equation of fractional order. [ABSTRACT FROM AUTHOR]

In the present article, we introduce a new concept of contraction and prove a new type of the extension of Tychonoff fixed point theorem. Then, as an application, we study the problem of existence of solutions for the infinite systems of integral equations using the technique of measures of noncompactness in conjunction with this extension in the Fréchet spaces.

The objective of this article is to establish a fixed point theorem using different class of control functions, which is a generalization of Darbo's fixed point theorem (DFPT) and its various versions obtained by several authors. Using this result we obtain existence of at least one positive solution for a quadratic integral equation of Fredholm type. [ABSTRACT FROM AUTHOR]

In this study, the potential of 8-Hydroxyquinoline grafted SBA-15 to extract of Cu2+ cations from aqueous solutions was investigated. SBA-15 nanoporous silica was chemically grafted with 8-Hydroxyquinoline groups according to the procedure in the literature. The presence of organic groups in the silica framework was demonstrated by FTIR spectrum. The grafted product showed the BET surface area 458 m2g-1 and pore diameter 54 °A, based on adsorption-desorption of N2 at 77 °K.. Flame atomic absorption spectrometry was used to determination of the ions concentration in the recovery and sample solution. The effects of several variables (amount of adsorbent, stirring time, pH and the presence of other metals in the medium) were studied. Cu2+ ions were completely extracted at pH= 4.5-7 after stirring for 15 minutes. The maximum capacity of the adsorbent was found to be 31.25 mg of Cu2+ per each gram of 8-Hydroxyquinoline grafted SBA-15. The minimum amount of acid for stripping of ions from grafted SBA-15 was tested and the preconcentration factor of the method was found 50. Finally, the proposed method was successfully applied as a new solid extractor to preconcentration and determination of trace amounts of Cu2+ ions in spiked distilled and tap water samples.

Abstract The aim of this article is to prove the existence of solution for nonlinear quadratic integral equations using the generalized form of Darbo fixed point theorem with the help of measure of noncompactness and simulation type condensing operator in the Banach space L 2[0, 1]. To illustrate validity of the analytical results, we present a nonlinear integral equation as an application. Finally, we introduce an iteration algorithm by modified homotopy perturbation and Adomian decomposition method to find solution of the above problem with a high accuracy. [ABSTRACT FROM AUTHOR]

In this paper we have introduced a new type of contraction condition using a class of simulation functions, in the sequel using the new contraction definition, involving measure of noncompactness; we establish few results on existence of fixed points of continuous functions defined on a subset of Banach space. This result also generalizes other related results obtained in Arab [Arab, R., Some generalizations of Darbo fixed point theorem and its application, Miskolc Math. Notes, 18 (2017), No. 2, 595-610], Bana's [Bana's, J. and Goebel, K., Measures of Noncompactness in Banach Spaces, Lecture Notes in Pure and Applied Mathematics, Dekker, New York, 60 (1980)]. The obtained results are used in establishing existence theorems for a class of nonlinear quadratic equation (which generalizes several types of fractional-quadratic integral equations such as Abel's integral equation) defined on a closed and bounded subset of R. The existence of solution is established with the aid of a measure of noncompactness defined on function space C(I) introduced in [Bana's, J. and Olszowy, L., Measures of Noncompactness related to monotonicity, Comment. Math., 41 (2001), 13-23]. [ABSTRACT FROM AUTHOR]

In the present study, we work on the problem of the existence of positive solutions of fractional integral equations by means of measures of noncompactness in association with Darbo's fixed point theorem. To achieve the goal, we first establish new fixed point theorems using a new contractive condition of the measure of noncompactness in Banach spaces. By doing this we generalize Darbo's fixed point theorem along with some recent results of (Aghajani et al. (J. Comput. Appl. Math. 260:67-77, 2014)), (Aghajani et al. (Bull. Belg. Math. Soc. Simon Stevin 20(2):345-358, 2013)), (Arab (Mediterr. J. Math. 13(2):759-773, 2016)), (Banaś et al. (Dyn. Syst. Appl. 18:251-264, 2009)), and (Samadi et al. (Abstr. Appl. Anal. 2014:852324, 2014)). We also derive corresponding coupled fixed point results. Finally, we give an illustrative example to verify the effectiveness and applicability of our results. [ABSTRACT FROM AUTHOR]

In this paper, the concept of contraction via the measure of non-compactness on a Banach space is investigated by generalizing some results which have been previously discussed in literatures. Furthermore, to validity of the theorems and homotopy perturbation method (HPM), as a technical solution, they are applied on some nonlinear singular integral equations. [ABSTRACT FROM AUTHOR]

The aim of this paper is to introduce a new measure of noncompactness on the Sobolev space $W^{n,p}[0,T]$.

In the present paper, we first investigate the construction of compact sets of $\mathit{DC}^{n}[J,E]$ and $C^{n}_{0}[J,E]$, and then we introduce new measures of noncompactness on these spaces. In addition, as an application, we discuss the existence of solutions of initial value problems for nth-order nonlinear integro-differential equations of mixed type on an infinite interval in Banach spaces. We will also state an interesting example which shows that our results can apply for solving infinite systems of integro-differential equations. [ABSTRACT FROM AUTHOR]

In this article, using the concept of measure of noncompactness, we give some results concerning the compactness and continuity of the nonlinear Volterra and Fredholm integral operators on the space BC(Ω) (Ω) is an unbounded subset of the Euclidean space ℝn). Then, we prove an existence result for a functional integral equation which includes several classes of nonlinear integral equations. Our results generalize and improve some previous works. We will also include some examples which show that our results are applicable where the previous ones are not. [ABSTRACT FROM AUTHOR]

Samet et al. in (Nonlinear Anal. 75:2154-2165, 2012) introduced the concepts of α- ψ-contractive type mappings and α-admissible mappings in metric spaces. The purpose of this paper is to present a new class of almost contractive mappings called almost generalized $(\alpha\mbox{-}\psi\mbox{-}\varphi\mbox {-}\theta)$-contractive mappings and to establish some fixed and common fixed point results for this class of mappings in complete ordered b-metric spaces. Our results improve and generalize several known results from the current literature and its extension. Moreover, an application to integral equations is given here to illustrate the usability of the obtained results. [ABSTRACT FROM AUTHOR]

The purpose of this paper is to obtain some common fixed point results for two mappings satisfying various contractive conditions in metric-like spaces. These results extend some previous results in the literature, since the condition under which the operator admits common fixed points is more general than the others in literature. Therefore, several well known results are generalized. As an application we use these results to existence of solution for nonlinear quadratic integral equation. To credibility, we apply modified homotopy and Adomian decomposition method to find solution of the above problem with high accuracy. [ABSTRACT FROM AUTHOR]

Abstract: To assess the presences of Escherichia coli, its serogroups, virulence factors and antibiotic resistance properties in ruminant's meat, a total of 820 raw meat samples were collected and then evaluated using culture, PCR and disk diffusion methods. Totally, 238 (29.02%) samples were positive for presence of Escherichia coli. All of the isolates had more than one virulence gene including Stx1, Stx2, eaeA and ehly. All investigated serogroups were found in beef and sheep and all except O145, O121 and O128 were found in goat. The O91, O113, O111, O103, O26 and O157 serogroups were found in camel. Totally, aadA1–blaSHV combination was the most predominant antibiotic resistance gene. The highest resistance of STEC strains was seen against penicillin while resistance to nitrofurantoin and ciprofloxacin was minimal. These findings showed that health care and meat inspection should be reconsidered in Iranian slaughterhouses and butchers. [Copyright &y& Elsevier]

In this article, we establish the existence of solution for two dimensional nonlinear fractional integral equation using fixed point theorem and measure of noncompactness. Applicability of our results is shown by some examples and for validity of the proposed method we make an iterative algorithm by semi-analytic technique that finds a closed form of the solution with an acceptable accuracy. Ability of the proposed method is granted by comparison with another method found in existing literature. [ABSTRACT FROM AUTHOR]
