L-forms are cell wall-deficient bacteria that divide through unusual mechanisms, involving dynamic perturbations of the cellular shape and generation of vesicles, independently of the cell-division protein FtsZ. Here we describe FtsZ-independent mechanisms, involving internal and external vesicles, by which Listeria monocytogenes L-forms proliferate. Using micromanipulation of single cells and ...

The purpose of this study was to evaluate the reliability and concurrent validity of 2 short forms of the Visual Form Discrimination Test, referred to as first half (FH) and front-back (FB). Participants were a mixed sample of 225 patients seen for neuropsychological evaluations. The mean difference score between both short forms and the full form was less than 1 point. The short-total correlat...

In this paper, a new analytical method to find a near-optimal high gain controller for the non-minimum phase affine nonlinear systems is introduced. This controller is derived based on the closed form solution of the Hamilton-Jacobi-Bellman (HJB) equation associated with the cheap control problem. This methodology employs an algebraic equation with parametric coefficients for the systems with s...

this article has tried to investigate the concept of cultural capital. hence, the question is that how the concept of cultural capital in internal and external researches has been measured? and what proportion of different variables has reported with cultural capital concept? in this paper relying on internal and external researches, first, the concept of cultural capital and its dimensions hav...

The major reason for the prediction of thermodynamic properties of mercury lies in the fact that itsintermolecular interactions highly depend on temperature and density. Internal pressure is a good criterion toinvestigate the density dependence of the interatomic interactions. Because its physical base is a forcetending to close together the molecules that is intermolecular interactions, and as...

In this paper, an analytical solution for computing the linear plastic stresses and critical pressure in a FGM hollow cylinder under the internal pressure due to non-Axisymmetric Loads is developed. It has been assumed that the modulus of elasticity was varying through thickness of the FGM material according to a power law relationship. The Poisson's ratio was considered constant throughout the...

· Posterior Circulation Two vertebral arteries originate from the first part of the subclavian arteries. These join intra-cranially to form the basilar artery and supply the posterior cerebral circulation. This is the main blood supply to the brain stem, cerebellum and posterior cerebrum. · Anterior Circulation Both internal carotid arteries arise from the carotid bifurcation in the neck. Intra...

For complex valued sequences {ωn}∞n=1 of the form ωn = an + ibn with an ∈ R and bn ≥ 0, we prove inequalities of the form ∫ T 0 | ∑∞ n=p xne itωn |2dt 3 ∞n=p |xn|/(1+bn), for all sequences {xn} with ∑∞ n=1 |xn|/(1 + bn) < ∞. We apply these to prove exact null-controllability for a class of hinged beam equations with mild internal damping with either boundary control or internal control.
