In a recent paper of Tamura, Merkel, and Latimer [2], the following question was raised: Suppose 5 is a groupoid (cf. [l]) which satisfies: (1) There is at least one left identity in S. (2) If y or z is a left identity of 5, then x(yz) =■= (xy)z for all xES. (3) For all a, bES there exists x£5 such that ax = b. Then does S satisfy: (3') For any xES there is a unique left identity e (which may d...

conclusions: catheter ablation of flutter circuit will not prevent later manifestation of af in 16% of the patients undergoing catheter ablation of the typical afl. bmi was the only independent predictor of af following catheter ablation of the typical afl. objectives; to determine long-term incidence and predictors of af after catheter ablation of typical afl. material and methods: between mar...

The purpose of this experimental study was to evaluate the effect of chicken amniotic fluid (AF) on a cross section of rat sciatic nerves. Thirty adult male Sprague-Dawley rats weighing 275 to 300 g, were randomized into three groups treated with (1) amniotic fluid or AF (n=10), (2) normal saline or NS (n=10), and (3) sham surgery (n=10). The AF was aspirated from the amniotic cavity of incubat...

It has recently been claimed that many of the discrete time-frequency representations (TFRs), including the alias free generalize time-frequency distributions (AF-GDTFD), contain aliasing components. This paper shows that the class of AF-GDTFD does indeed displace both cross term and auto term energy in ways not characteristic of continuous TFRs, but this energy displacement does not satisfy ou...

Toyama's Theorem states that connuence is a modular property of disjoint term rewriting systems. This theorem does not generalize to combined systems with shared constructors. Thus the question arises naturally whether there are suucient conditions which ensure the modu-larity of connuence in the presence of shared constructors. In particular, Kurihara and Krishna Rao posed the problem whether ...

the prevalence of atrial fibrillation (af) is 1-2 % in the general population, and the risk of embolic stroke in af patients is 4-5 times higher than that in the general population. af-related strokes are often severe, and the rate of permanent disability is much higher among individuals who have af-related strokes than in those who have strokes unrelated to af. in patients with af, more than 9...

this study was carried out to evaluate how various amounts of nanozeolite decrease the effects of aflatoxins (af) on color and oxidative stability of the broiler thigh meat. three hundred and thirty six one-day-old ross 308 male broiler chickens were divided into six groups including a control group, which received diet without af and nanozeolite, and five treatment groups that received diet wi...
