The required level of complexity the arm wrestlers’ competitive activities demands high requirements for functional state spine. Irrational approach to training process without taking into account biogeometric profile prevents improvement physical qualities, which leads a violation cycle, reduced athletic performance and efficiency. One most important conditions postural disorders in athletes i...

We produce an explicit parameterization of well-rounded sublattices of the hexagonal lattice in the plane, splitting them into similarity classes. We use this parameterization to study the number, the greatest minimal norm, and the highest signal-to-noise ratio of well-rounded sublattices of the hexagonal lattice of a fixed index. This investigation parallels earlier work by Bernstein, Sloane, ...

We prove that the well-rounded retract of SOn \ SLn R is a minimal SLn Z-invariant spine.

Rounded atelectasis is an atelectasis of a peripheral part of the lung due to pleural adhesions and fibrosis causing deformation of the lung and bending of some small bronchi. From 1970 to 1986, some 74 patients with rounded atelectasis have been seen at the Lung Department. Sixty-four of these patients had been exposed to asbestos. The lesion was secondary to a benign asbestos pleurisy in nine...

The results of anatomic total shoulder arthroplasty and reverse shoulder arthroplasty have previously been reported separately. Although the indications differ, scenarios exist in which a patient may have a total shoulder arthroplasty on 1 shoulder and a reverse shoulder arthroplasty on the contralateral shoulder.Between 1992 and 2009, twelve patients underwent bilateral sequential primary shou...
