We describe the first-order variations of the angles of Euclidean, spherical or hyperbolic polygons under infinitesimal deformations such that the lengths of the edges do not change. Using this description, we introduce a vector-valued quadratic invariant b on the space of those isometric deformations which, for convex polygons, has a remarkable positivity property. We give two geometric applic...

Introduction: Most current evidence suggests the risk of left atrial and or auricular thrombi(LA &LAA) in patients with atrial flutter rhythm is similar to patients with atrial fibrillation, but there is still uncertainty in the risk level and the patient's need to receive anticoagulant therapy. Different studies report various frequencies for atrial thrombi and left atrial spontaneous echo-con...

In this paper the results of X-ray diffraction experiments of Ln-Si-Al-O-N (Ln = La, Gd, Yb) glasses are presented. Total structure factors and pair correlation functions allow the determination of the first coordination sphere of Ln atoms. The bond lengths observed correspond to the ionic radii of the Ln-ions surrounded by oxygen and nitrogen atoms. The presence of non-bridging nitrogen is dis...

The distribution of some rare earth elements (La, Ce, Sc, and Y) in the sediment samples, collected form 56 stations in the offshore of the Persian Gulf during the Persian Gulf and Gulf of Oman Oceanographic Cruise (PGGOOS) in 2012, was studied. The elements were determined by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). The result revealed that the concentration of Ce (82 µg g-1) was...
