Abstract:

BACKGROUND: It has been demonstrated that maximum isometric muscle moment can surpass maximum eccentric muscle moment at individually adjusted joint angles in men. However, no information about these muscle mechanics is available for women. OBJECTIVE: To examine the maximum muscle moment hierarchy with equal conditions in women. METHODS: Maximum voluntary concentric, eccentric, and isometric muscle moments of ankle, knee, and hip flexors and extensors as well as hip adductors and abductors were tested in eighteen young women. The sequence of muscle group testing was the same for all subjects,

Abstract:

Fixed point theorems had been established and developed under various non-expansive type conditions on different metric spaces. In this paper, we have generalized (ψ,φ) - weak contractions, which is the generalizations of F-contraction, (ϕ,F)-contraction as well as (ψ,φ)-contractions. Then we have established some unique common fixed point results for a sequence of mappings for (ψ,φ)- weak contractions in 2-Banach spaces. Some basic definitions, properties and examples are given in the introduction and preliminaries part. Some corollaries are also given on the basis on the results.

Abstract:

The C-terminal domain (CTD) is an essential domain of the largest subunit of RNA polymerase II, Rpb1p, and is composed of 26 tandem repeats of a seven-amino acid sequence, YSPTSPS. Despite being an essential domain within an essential gene, we have previously demonstrated that the CTD coding region is genetically unstable. Furthermore, yeast with a truncated or mutated CTD sequence are capable of promoting spontaneous genetic expansion or contraction of this coding region to improve fitness. We investigated the mechanism by which the CTD contracts using a tet-off reporter system for RPB1 to mo

Afterwards, Mustafa et al and many authors [3]-[19] obtained some common fixed-point theorems, coupled and tripled fixed point results for mappings satisfying different contractive conditions in G metric space.

Abstract:

With the use of the radionuclide gastric-emptying test and a new data processing method, the contraction characteristics of the stomach were analyzed. After ingestion of a radiolabeled test meal, dynamic images of the stomach were acquired and analyzed to determine the frequency, amplitude, and rate of gastric contractions in healthy subjects. The frequency of antral contractions was found to be inversely related with food retention in the stomach; in contrast, the amplitude of the contractions decreased progressively during the course of gastric emptying.

The aim of the present experiments was to verify whether group II inputs from gastrocnemius medialis (GM) muscle could elicit declining inhibitions similar to those observed during GM contractions in a variety of lumbar motoneurons of the cat spinal cord. Motoneurons were recorded intracellularly in chloralose- or pentobarbitone-anesthetized preparations during electrical stimulation of GM nerve with repetitive trains. 2. With strengths in the group I range, repetitive stimulation evoked the usual Ia excitation in homonymous motoneurons and excitatory postsynaptic potential (EPSP) amplitude

Instead of strict repetition, she varies many elements of the melodic surface thro

Mental illness and substance abuse are separate and additive risk factors for HIV infection. A comprehensive approach in the treatment of those with the dual diagnosis of mental illness and substance abuse is very important because these patients are inherently at a higher risk of contracting or transmitting sexually transmitted diseases, including HIV. Problems with adherence to medical treatment seem to be additive in this group. In addition, substance abuse is associated with a host of medical sequelae (liver disease, infection, diabetes, cardiovascular disease, and neurocognitive changes),

AbstractThis paper studies nested sequents for quantified modal logics. In particular, it considers extensions of the propositional modal logics definable by the axioms D, T, B, 4, and 5 with varying, increasing, decreasing, and constant domains. Each calculus is proved to have good structural properties: weakening and contraction are height-preserving admissible and cut is (syntactically) admissible. Each calculus is shown to be equivalent to the corresponding axiomatic system and, thus, to be sound and complete. Finally, it is argued that the calculi are internal—i.e., each sequent has a for

Fibrous proteins made by α-helices, one of the most elementary protein secondary structures, have various mechanical roles in a sub cellular environment. An α-helix is wound in a right-handed fashion due to hydrogen bonding between the C=O and the N-H atoms across every i and i+4th residues in the polypeptide chain. Previous approaches characterizing mechanical properties of α-helices treated them as homogenous and linear elastic rods.

Abstract A typical type-B sleeve consists of two half cylinders fillet-welded to the carrier pipe and joined together with butt welds.

The orientation and severity of the residual stresses can be reduced depending on the installation method. For instance, the residual stresses may differ if the upstream and downstream fillet welds are installed simultaneously versus sequentially, as simultaneous w
