Research ArticleOpen accessEvery word in the titlePhysical and Geometrical Effects on the Vibratory Pattern of a Pipe Carrying Fluid FlowDahmane Mouloud, Samir Zahaf, Mawhoub Soubih et al.In this research, the first natural frequencies and critical velocities of a fluid flow-conveying pipe are obtained with finite element method. By discretizing the structure wall and fluid flow, starting from beam type with two degrees of freedom per node. We determine the equation of motion from the fluid-structure coupling using Lagrange energy principle. Parameters frequencies and critical velocity of … …Current Research in Bioinformatics, Vol. 9, Issue 1 · 22 Oct 2020 · 11,396 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFREE ENERGY MEASUREMENT DISTINGUISHES NORMAL FROM CANCER CELL, OFFERING A NEW PERSPECTIVE FOR CURING CANCERKambiz Afrasiabi, Jonathan Melekh-ShalomThe interplay of the second law of thermodynamics with the normal state and the methodology needed for the measurement of free energy of normal and malignant cells and its practical implications has not been clearly addressed in current literature. The second law of thermodynamics is one of the most fundamental laws governing the known universe at all levels. A normal … …OnLine Journal of Biological Sciences, Vol. 13, Issue 4 · 12 Oct 2013 · 7,224 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFour Dimensional (4-D) BioChemInfoPhysics Models of Cardiac Cellular and Sub-Cellular Vibrations (Oscillations)Kang Cheng, Chang-Hua ZouProblem statement: Cardiovascular Diseases (CVD) continued to be the leading cause of death. Failure or abnormal cardiac cellular or sub-cellular vibrations (oscillations) could lead failure or abnormal heart beats that could cause CVD. Understanding the mechanisms of the vibrations (oscillations) could help to prevent or to treat the diseases. Scientists have studied the mechanisms for more than 100 years. To … …OnLine Journal of Biological Sciences, Vol. 9, Issue 2 · 15 Jun 2009 · 7,057 accessesView PDF Cite
