conclusions the treatment of symptomatic ecu instability is still controversial, especially for acute dislocations. depending on the type of injury many surgical techniques have been proposed. combination of direct repair of the tendon’s subsheath and reinforcement with an extensor retinaculum graft is a reliable option. introduction dislocation/subluxation of the extensor carpi ulnaris (ecu) t...

Local hydromagnetic simulations of accretion disc turbulence provide now the most convincing evidence that the origin of turbulence in discs could be the Balbus{Hawley magneto-rotational instability. The main results of such calculations are highlighted with particular emphasis on the generation of large scale magnetic elds. Comparison with mean-eld dynamo theory is made. This theory is then us...

A nonlinear integral-differential equation describing the cellular front of an overdriven detonation is obtained by an analysis carried out in the neighborhood of the instability threshold. The analysis reveals both an unusual mean streaming motion, resulting from the rotational part of the oscillatory flow, and pressure bursts generated by the crossover of cusps representative of Mach stems pr...

Recent simulations of supernova-driven turbulence within the ISM support the existence of a large-scale dynamo. With a growth time of about two hundred million years, the dynamo is quite fast – in contradiction to many assertions in the literature. We here present details on the scaling of the dynamo effect within the simulations and discuss global meanfield models based on the adopted turbulen...

A core–collapse supernova might produce large amplitude gravitational waves if, through the collapse process, the inner core can aquire enough rotational energy to become dynamically unstable. In this report I present the results of 3-D numerical simulations of core collapse supernovae. These simulations indicate that for some initial conditions the post–collapse inner core is indeed unstable. ...

This paper presents a trajectory tracking control method for flexible space robot. The advantage of the method is that it is free from spill-over instability as it uses a robust overwhelming trajectory controller. The proposed controller is conceptualized for a single rotational degree of freedom case. The efficacy of the scheme is illustrated by simulation results. The stability analysis of th...

We describe a singular case of both ischemic and traumatic complication, referring to use of new devices used for endovascular approach, in the same patient. One is a hemostatic closure device (Angio-Seal® St. Jude Medical) and the other is a catheter for percutaneous rotational and aspiration thrombectomy (Rotarex® Straub Medical). We discuss indication to use these devices in severely ill pat...
