Berinde [V. Berinde, Approximating fixed points of weak contractions using the Picard iteration, Nonlinear Anal. Forum {bf 9} (2004), 43-53] introduced almost contraction mappings and proved Banach contraction principle for such mappings. The aim of this paper is to introduce the notion of multivalued almost $Theta$- contraction mappings andto prove some best proximity point results for t...

Let $n\ge 1$ and $s\ge be integers. An almost $s$-stable subset $A$ of $[n]=\{1,\dots,n\}$ is a such that for any two distinct elements $i, j\in A$, one has $|i-j|\ge s$. For family $\cal F$ non-empty subsets $[n]$ an integer $r\ge 2$, the chromatic number $r$-uniform Kneser hypergraph $\mbox{KG}^r({\cal F})$, whose vertex set edge $\{A_1,\dots, A_r\}$ pairwise disjoint in F$, been studied exte...

A bstract Using 6 . 32 fb ? 1 of e + collision data collected at the center-of-mass energies between 4.178 and 4.226 GeV with BESIII detector, we perform an amplitude analysis decay $$ {D}_s^{+} D s + ? K ? determine amplitudes various intermediat...

Bu çalışmada, trisiklik antidepresanlara alternatif olarak kullanılan selektif serotonin geri alım inhibitörleri (SSRİ)’nden sitalopram, fluvoksamin ve sertralinin su-asetonitril ikili karışımında, ters faz sıvı kromatografik (RPLC) yöntemle alıkonma davranışı incelenmiştir. Kromatografik analizler, mobil pH’sı 6,5 ila 10,5 arasında değişen, %45-%55 (h/h) asetonitril içeren asetonitril-su karış...

Boujari [5] proved a fixed point theorem with an old version of the integraltype contraction , his proof is incorrect. In this paper, a new generalizationof integral type contraction is introduced. Moreover, a fixed point theorem isobtained.

in the present paper‎, ‎we introduce the concept of generalized multivalued $f$ -‎contraction mappings and give a fixed point result‎, ‎which is a proper‎ ‎generalization of some multivalued fixed point theorems including nadler's‎.

in this paper, we prove some common fixed point results for two self mappingsf and g on s-metric space such that f is a g.w.c.m with respect to g.

background and aims: the antioxidant and anti-inflammatory effects of carvacrol were reported. the aim of the current study was an investigation the relaxant effects of carvacrol on acetylcholine-induced contraction in isolated rat's ileum. materials and methods: in this study, the tissues separated from ileum were fixed on the organ bath containing tyrode's solution. the amplitude of...

introduction: thymol has negative ionotropic effect on heart and has direct effect on calcium release from sarcoplasmic reticulum. some of the herbal plants just like carum copticum consist of thymol. the postganglionic neurons of the gastrointestinal parasympathetic system are located mainly in the myenteric and submucosal plexuses. stimulation of these parasympathetic nerves causes general in...

in a fuzzy metric space (x;m; *), where * is a continuous t-norm,a locally fuzzy contraction mapping is de ned. it is proved that any locally fuzzy contraction mapping is a global fuzzy contractive. also, if f satis es the locally fuzzy contractivity condition then it satis es the global fuzzy contrac-tivity condition.
