RELATIONSHIP OF THE CONDITION OF THE MYOCARDIUM WITH INFRINGEMENTS THE CALCIUM AND PHOSPHORUS METABOLISM INPATIENTS WITH DIABETIC NEPHROPATHY

Objective: To establish the possible relationship between changes in cardiac hemodynamics and im-paired phosphate-calcium metabolism and content FGF 23. Patients and Methods: 260 people with diabetic nephropathy, 64 people with hypertension and 20 healthy individu-als were surveyed. Studied the state of the myocardium and cardiac hemodynamics, blood levels of calcium, phosphorus and FGF 23. Results and conclusions: between the state of myocardium, cardiac hemodynamics and content FGF23, phos-phorus and calcium are closely interrelated, which is likely mediated through specific receptor apparatus of myocardium and through immunoinflammatory mechanisms. However, the specific mechanisms of action system FGF23 / phosphorus-calcium exchange for anatomical and functional myocardial changes require further investigation

Spontaneous Magnetization and Electron Momentum Density in 3D Quantum Dots

We discuss an exactly solvable model Hamiltonian for describing the interacting electron gas in a quantum dot. Results for a spherical square well confining potential are presented. The ground state is found to exhibit striking oscillations in spin polarization with dot radius at a fixed electron density. These oscillations are shown to induce characteristic signatures in the momentum density of the electron gas, providing a novel route for direct experimental observation of the dot magnetization via spectroscopies sensitive to the electron momentum density.Comment: 5 pages (Revtex4), 4 (eps) figure

Unmanned Aircraft Navigation for Shipboard Landing using Infrared Vision

IEEE Transactions on Aerospace and Electronic Systems, October 2002, vol. 38 no. 4, pp. 1181-1200This paper addresses the problem of determining the relative position and orientation of an unmanned air vehicle with respect to a ship using three visible points of known separation. The images of the points are obtained from an onboard infrared camera. The paper develops a numerical solution to this problem. Both simulation and flight test results are presented
