This paper analyzes an induction motor with high temperature superconducter (HTS) coated slotted solid rotor. By slotting the solid rotor, the electromagnetic torque near synchronous speed will increase but the starting torque will decrease. To improve starting torque, rotor slots are coated with HTS materials. Using HTS material vary the rotor resistance to great extends in starting step and t...

We construct a family of closed string solutions with kinks in a subspace of AdS5 × S and study their properties. In certain limits these solutions become folded pulsating strings, although in general they are made of multiple pulsating rectangles. One unusual feature of these solutions is that their monodromy matrices are trivial, leading to vanishing quasi-momenta. Exact Bäcklund transformati...

Introduction: Some clinicians use a handheld screw driver instead of a torque wrench to definitively tighten abutment screws. The aim of this study was to compare the removal torque of one-piece and two-piece abutments tightened with a handheld driver and a torque control ratchet. Methods: 40 ITI implants were placed in acrylic blocks and divided into 4 groups. In groups one and two, 10 ITI one...

Post-nodal pieces of the stage-4 chick blastoderms were transected 0-6 mm posterior to Hensen's node and cultured in vitro with and without chicken-heart RNA. After 24 h the explants were fed daily with fresh egg-extract medium for 4 days. On the 4th day pulsating heart was found in the RNA-treated but not in the untreated series. Histological examination revealed that cell differentiation othe...

The presence of pulsating varicous veins is an uncommon finding, generically attributed to right heart failure. The precise causes of this phenomenon have been poorly defined in the literature. The finding of this infrequent condition is important because it may be a sign of major diseases, often not known. Here we described a 75-year-old woman presented to the Angiology Unit for the presence o...

In this paper we are interested in propagation phenomena for nonlocal reaction-diffusion equations of the type: ∂u ∂t = J ∗ u− u+ f(x, u) t ∈ R, x ∈ R , where J is a probability density and f is a KPP nonlinearity periodic in the xvariables. Under suitable assumptions we establish the existence of pulsating fronts describing the invasion of the 0 state by an heterogeneous state. We also give a ...

Stationary to pulsating soliton bifurcation analysis of the complex Ginzburg–Landau equation (CGLE) is presented. The analysis is based on a reduction from an infinite-dimensional dynamical dissipative system to a finite-dimensional model. Stationary solitons, with constant amplitude and width, are associated with fixed points in the model. For the first time, pulsating solitons are shown to be...

We present follow-up observations of pulsating subdwarf B (sdB) stars as part of our efforts to resolve the pulsation spectra for use in asteroseismological analyses. This paper reports on multisite campaigns of the pulsating sdB stars PG 1618+563B and PG 0048+091. Data were obtained from observatories placed around the globe for coverage from all longitudes. For PG 1618+563B, our five-site cam...
