the effects of anterior discectomy and interposition al implant upon lumbar motion segment stability
the cadaver spine motion segment behavior under torsional load was evaluated with the disc intact, with partial anterior discectomy and with spacer insertion. the results of this study explain how anterior lumbar discectomy and interbody fusion (alif) affects the torsional stability of the motion segment. the pseudarthrosis rate of the anterior lumbar discectomy and interbody fusion (alif) is k...
in this paper, we prove the nonexistence of two weighing matrices of weight 81, namely $cw(88,81)$ and $cw(99,81)$. we will apply two very different methods to do so; for the case of $cw(88,81)$, we will use almost purely counting methods, while for $cw(99,81)$, we will use algebraic methods.
Biomonitoring using birds of prey as sentinel species has been mooted as a way to evaluate the success of European Union directives that are designed to protect people and the environment across Europe from industrial contaminants and pesticides. No such pan-European evaluation currently exists. Coordination of such large scale monitoring would require harmonisation across multiple countries of...
BACKGROUND AND PURPOSE Few data are available on the frequency and location distribution of fenestrations of intracranial arteries. We used 3D rotational angiography of all intracranial arteries in a cohort of 179 patients with suspected intracranial aneurysms to assess the prevalence and location of fenestrations and the relation of fenestrations to aneurysms. MATERIALS AND METHODS Of 179 pa...
In this paper, we introduce the concept of generalised inverse (ginverse) for intuitionistic fuzzy matrices (IFMs). We define minus partial ordering and studied several properties of it. Here we have shown that the minus partial ordering is a partial ordering for IFMs.

We will establish lower bounds in terms of the level for the number of holomorphic cusp forms of weight k > 2 whose various L-functions do not vanish at the central critical point. This work generalizes the work of W. Duke [1] which was for the case of weight 2.
in this paper we consider the group algebra $r(c_2times d_infty)$. it is shown that $r(c_2times d_infty)$ can be represented by a $4times 4$ block circulant matrix. it is also shown that $mathcal{u}(mathbb{z}_2(c_2times d_infty))$ is infinitely generated.
let $cr_{n}(f)$ denote the algebra of $n times n$ circulant matrices over the field $f$. in this paper, we study the unit group of $cr_{n}(f_{p^m})$, where $f_{p^m}$ denotes the galois field of order $p^{m}$, $p$ prime.
