Abstract This article proposes four distinct kinds of symmetric contraction in the framework complete F-metric spaces. We examine condition to guarantee existence and uniqueness a fixed point for these contractions. As an application, we look solutions fractional boundary value problems involving generalized derivative known as with respect another function.

‎In this work four uncertain delay differential equations of Volterra-Levin type will be considered‎. ‎Applying suitable contraction mapping and fixed point method‎, ‎the stability the studied‎. ‎It shown that solutions are bounded and‎, ‎with additional condition‎, tend to zero‎. ‎Also‎, ‎a necessary sufficient condition for asymptotic an equation presented‎.

In this paper we give some common fixed point theorems for ?iri? type operators in complex valued b-metric spaces. Also, corollaries under contraction condition are obtained. Our results extend and generalize the of Hammad et al. second part paper, order to strengthen our main results, an illustrative example applications given.

During the contraction phase of isotonic twitch there must be the change of muscle force. When initial acceleration was augmented by using heavy load or inertia lever 1,2,3), the muscle tension developed far bigger than the load and the condition of twitch was not 'isotonic' in real meaning. As far as a single twitch was concerned, the change of force should not be neglected. In the previous st...

The stretch-shortening cycle is one of the most interesting topics in the field of sport sciences, because the performance of human movement is enhanced by the stretch-shortening cycle (eccentric contraction). The purpose of the present study was to examine whether the influence of preactivation on the torque enhancement by stretch-shortening cycle in knee extensors. Twelve men participated in ...

Banach contraction principle is a fundamental result in fixed point theory and has been applied and extended in many different directions. In 2002, Branciari [3] obtained a fixed point theorem for a single mapping satisfying an analogue of Banach’s contraction principle for an integral type inequality. Aliouche [2] established a common fixed point theorem for weakly compatible mappings in symme...

Employing the common property E.A , we prove some common fixed point theorems for weakly compatible mappings via an implicit relation in Menger PM spaces. Some results on similar lines satisfying quasicontraction condition as well as ψ-type contraction condition are also proved in Menger PM spaces. Our results substantially improve the corresponding theorems contained in Branciari, 2002 ; Rhoad...

The earliest reference that we found in the medical literature to the condition that ultimately came to be known as Dupuytren’s Disease was a report by Felix Plater in the 17 century. Plater described a stone mason with “contraction of the fingers of the left hand into the palm” [1]. However, he mistakenly attributed the condition to contracture of the tendons, rather than of the palmar fascia ...

Abstract Objective To investigate the cutaneous silent period (CSP) by measuring its onset latency, duration and amount signal suppression in patients with motor neuron disease (MND) grouped according to intensity of upper involvement (UMN), test effect contralateral hand contraction. Methods Painful stimulation was applied at V finger, contraction recorded from abductor digiti minimi (ADM) mus...

purpose: this study aimed to examine the differences in the co-activation of the rectus femoris (rf) and biceps femoris (bf) using the co-contraction index (ci) in aquatic and land environments during a drop-landing task in active and non-active females. methods: in this casual-comparison study, 10 active and 10 non-active females volunteered to participate. the ci was calculated from recorded ...
