New inclinometers devoted to hydrological studies were set up in the Vosges Mountains (France). Two orthogonal 100-meter base hydrostatic inclinometers were installed in December 2004 as well as a hydrometeorological monitoring system for the 100-km2 hydrological unit around the inclinometer. As inclinometers are very sensitive to environmental influences, this observatory is a test site to con...

A new biplanar x-ray imaging system acquires simultaneous lateral and anteroposterior images while the patient is in a weight-bearing position The imaging system uses novel slot-scanning technology that can acquire simultaneous orthogonal whole-body images at a fraction of the radiation dose of standard x-rays Indications include pathologies that change under load: Spinal problems such as scoli...

Trying to reveal the mechanism of gas seepage in coal is significance both safe mining and methane exploitation. A series FEM numerical models were built up studied so as explore mesoscale fractures. The proposed model a cube with micron fractures along three orthogonal directions. distribution velocity pressure under fluid-solid coupling was obtained, furthermore, flow flux an equivalent perme...

Unconsolidated pyroclastic flow deposits of the 1993 eruption of Lascar Volcano, Chile, have, with time, become increasingly dissected by a network of deeply penetrating fractures. The fracture network comprises orthogonal sets of decimeter-wide linear voids that form a pseudo-polygonal grid visible on the deposit surface. In this work, we combine shallow surface geophysical imaging tools with ...

Background: Subtrochanteric femur fractures remain challenging injuries to treat. There is paucity of literature evaluating their outcomes and complications following low-velocity civilian gunshots. The purpose of this study is to evaluate the results of intramedullary nailing of subtrochanteric femur fractures secondary to low-velocity gunshots. Methods: A retrospective review of clinical and ...

The concept of a linear ordered orthogonal array is introduced, and its equivalent geometrical configuration is determined when its strength is 3 and 4. Existence of such geometrical configurations is investigated. They are also useful in the study of (T, M, S)-nets.

introduction: restoration of normal anatomic alignment is a key component of the treatment of distal radius fractures (drf). this study aimed to evaluate the accuracy of ultrasonography (us) in determining the adequacy of closed reduction in these fractures. methods : drf patients admitted to the emergency department of al-zahra hospital, isfahan, iran from september 2011 to 2012, were enrolled...

two latin squares of order $n$ are orthogonal if in their superposition, each of the$n^{2}$ ordered pairs of symbols occurs exactly once. colbourn, zhang and zhu, in a seriesof papers, determined the integers $r$ for which there exist a pair of latin squares oforder $n$ having exactly $r$ different ordered pairs in their superposition. dukes andhowell defined the same problem for latin squares ...

Background: The purpose of this retrospective study was to analyze the long-term results of revision ORIF, jointcontracture release, and autogenous bone-grafting in the treatment of distal humerus frac-ture nonunions in older agedpatients with poor bone quality or bone loss who would have been candidates for total elbow arthroplasty.Methods: Seven patients (average age at inde...
