The feline anterior sartorius is a long strap-like muscle composed of short muscle fibers. Nerve branches that enter this muscle contain the axons of motor units whose constituent muscle fibers are distributed asymmetrically within the muscle. In the present study, twitch and tetanic isometric contractions were evoked by stimulating individual nerve branches while muscle force was recorded and ...

Let G be a graph, and let p(G) and c(G) be the order of a longest path and a longest cycle of G, respectively. In [J. Graph Theory 30 (1999), 91– 99], Saito proved that if G is a 2-connected graph with p(G)− c(G) ≥ 2, then p(G) ≥ σ3(G) − 1. In this paper, we evaluate the length of a longest path of G by using σ4(G). Specifically, our main results are the following. (i) If G is a 3-connected gra...

The paper describes a new tool for study relationships between length and coverage of exact decision rules. This tool is based on dynamic programming approach. We also present results of experiments with decision tables from UCI Machine Learning Repository.

Here tree dependency structures are studied from three different perspectives: their degree variance (hubiness), the mean dependency length and the number of dependency crossings. Bounds that reveal pairwise dependencies among these three metrics are derived. Hubiness (the variance of degrees) plays a central role: the mean dependency length is bounded below by hubiness while the number of cros...

Length-weight relationship and condition factor were estimated in seven fish species, including Barbus cyri, Capoeta gracilis, Alburnoides eichwaldii, Pseudorasbora parva, Ponticola cyrius, Cobitis keyvani and Acanthalburnus microlepis from Shahrbijar River, Guilan Province, Iran. A total of 416 specimens ranging from 18 to 135 mm in total length and from 0.06 to 19.25 g in total weight were co...

• The purpose of this paper is to present recent findings that define in greater detail the mechanical behavior of the myocardium. Investigation of the mechanical events associated with myocardial contraction involves at least three parts: 1) study of the contractile elements of the muscle itself, 2) study of the elastic and hydraulic machinery coupling the forces of the contractile elements to...

Abstract The Couffo basin is not well known, and neither are its aquatic living resources, such as fish fauna, which subjected to high exploitation rates. objectives of this study were establish length-weight ratios (LWRs) length-length (LLRs) for the most important species in catches those certain economic value. A total 12,191 specimens belonging 40 commercial actinopterygian fishes caught wi...
