The specific and selective detection of Salmonella typhymurium based on the use of a polyclonal antibody immobilized by the Langmuir-Blodgett method on the surface of a quartz crystal acoustic wave device was demonstrated in liquid samples. These biosensors were selective to S. typhymurium in the presence of large concentrations of Escherichia coli O157:H7. They were also specific to S. typhymu...

Rotating stellar models of 1.2 M down to 0.6 M have been computed to investigate the effects of rotation on the lithium depletion of low-mass, pre-main sequence stars. The models were generated under three different rotation laws (rigid body rotation, local conservation of angular momentum over the whole star, and local conservation of angular momentum in radiative zones and rigid body rotation...

Rigid QED is a renormalizable generalization of Feynman’s space-time action characterized by the addition of the curvature of the world line (rigidity). We have recently shown that a phase transition occurs in the leading approximation of the large N limit. The disordered phase essentially coincides with ordinary QED, while the ordered phase is a new theory. We have further shown that both phas...

Abstract Purpose In this paper, the analytic solution for a free rotatory motion under influence of motor limited power is investigated; we aim to prove that carrier body close rotation about fixed axis depending upon problem's parameters and initial conditions. Method Tensor calculus tools, asymptotic method, kinematic equations (EOM) are used. Results At large time, properties solutions syste...

We consider the motion of mechanical system consisting case (a rigid body) and inner mass material point). The circulates inside body on a circle centered at center body. suppose that absolute value velocity circular is constant. moves translationally rectilinearly flat horizontal surface with forces viscous friction dry Coulomb it. in vertical plane. perform full qualitative investigation dyna...

In this paper a simple model of a three story building with inclined first-story columns has presented. The stories are supposed to be rigid and are connected to axially rigid mass less columns by elasto-plastic rotational springs and linear rotational dampers. The considered model is subjected to horizontal component of fault normal pulse with different magnitudes and the governed nonlinear di...
