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.

and Applied Analysis 3 A partial metric space is a pair X, p such that X is a nonempty set and p is a partial metric on X. It is clear that, if p x, y 0, then from p1 and p2 x y. But if x y, p x, y may not be 0. Each partial metric p on X generates a T0 topology τp on X which has as a base the family of open p-balls {Bp x, ε : x ∈ X,ε > 0}, where Bp x, ε {y ∈ X : p x, y < p x, x ε} for all x ∈ ...

introduction: it was shown in a previous study, that mcpip, a cilostamide derivative, increased atrial contraction force without changing contraction rate. to improve this property, two new derivatives of cilostamide were synthesized and their effects on pde3 activity and isolated rat atria contraction were investigated. methods: the inhibitory effect of each compound on pde3 enzyme was determi...

boujari [5] proved a fixed 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.

A dynamical system is called contractive if any two solutions approach one another at an exponential rate. More precisely, the dynamics contracts lines This property implies highly ordered asymptotic behavior including entrainment to time-varying periodic vector fields and, in particular, global stability for time-invariant fields. Contraction theory has found numerous applications systems and ...
