Distal biceps tendon rupture is a relatively rare injury. It commonly occurs in the dominant extremity of middle-aged men during an excessive eccentric tension as the arm is forced from a flexed position, while it is rarely observed during sport activities. Many techniques, including non-operative and surgical option, have been described for the treatment of a ruptured distal biceps tendon, but there is still considerable controversy about the management of choice.
Nine patients affected with traumatic distal tendon ruptures of the biceps brachii were followed-up for a minimum of 24 months. Five patients underwent surgery (two-incision technique) and four patients were treated conservatively. Tendon readaptation to its origin was done by a suture metal anchor. Outcome was evaluated based on the physical examination, radiographic analysis and the SECEC elbow score.
The SECEC elbow score results show that every single item result is in favour of surgical treatment. On measurements of motion, we found a slight flexion-extension deficit in two patients, but reduced supination in six patients and reduced pronation in four. Two patients had postoperative dysfunction of the deep branch of the radial nerve. Radiographic examination showed heterotopic bone formation on the radial tuberosity around the presumed insertion of the reattached tendon in 2 of 5 patients and ectopic ossification more proximally in the area of the biceps muscle
Our findings confirm the view that anatomic repair of distal biceps tendon rupture provides consistently good results and early anatomic reconstruction can restore strength and endurance for the elbow.

    ABSTRACT: In this paper we consider the problem of the dynamical control of a system composed of two working stations; each station is modeled by a queue which feeds one or more machine tools. This system can be considered as a first simple Flexible Manufacturing System (FMS) which allows to be dynamically controlled and, if necessary, in real time too. Each queue has a limited capacity and is characterized by a set of differential equations, in which the variables are the queue state probabilities (Equations of Chapman-Kolmogorov). The queues are related each other by the condition that the throughput of the first queue is equal to the input rate of the second one. Control inputs are the service rates of the working stations and are obtained by minimizing a suitable functional. The minimization problem, formulated in terms of Pontryagin's minimum principle, is solved numerically by using the method of steepest descent. Optimal control was evaluated by simulation; the mean cost is substantially equal to the one obtained by computation.

    ABSTRACT: Front Aperture Detection (FAD) makes possible the detection of domains smaller than the optical diffraction limit and thus achieves magnetic super resolution (MSR) in magneto-optical (MO) recording. The success of this detection technique depends on good control of the shape and relative position of the thermal mask during the reading process. To have a better understanding of the reading dynamics in FAD, a high speed Kerr microscope system with 10 ns resolution built on an air bearing spin stand was used to directly observe the dynamics of the thermal mask and the effective aperture in FAD disks during readout. A computer simulation of the thermal profiles was compared with the experimental results and provides insight to the data analysis. It is shown that reading power, bias field and linear velocity affect the length of the thermal mask and the effective reading aperture. This effect strongly depends on the temperature gradient. Adding an Al underlayer to sharpen the thermal profile can reduce the dependence of the effective aperture on small changes in power and bias field during reading
