Asymptotically exact and nonlocal third order nonlinear evolution equations are derivedfor two counterpropagating surface capillary gravity wave packets in deep water in thepresence of wind flowing over water.From these evolution equations stability analysis ismade for a uniform standing surface capillary gravity wave trains for longitudinal perturbation. Instability condition is obtained and g...

The role of myogenic electrical activity in the coordination of circumferential contraction of the human colon circular muscle was investigated. Five suction electrodes were placed (5-7 mm apart) on isolated rings of human colon and simultaneously electrical and motor activities were measured. In normal Krebs solution, the slow waves were not synchronised in most preparations studied. The elect...

In an open-abdominal anesthetized and fasted canine model of the intact small intestine, the presence, location, shape, and frequency of spike patches were investigated. Recordings were performed with a 240-electrode array (24 x 10, 2-mm interelectrode distance) from several sites sequentially, spanning the whole length of the small intestine. All 240 electrograms were recorded simultaneously d...

Recently, with the development of detonation-based propulsion systems, scholars have begun to study how perform mode control on rotating detonation combustor (RDC). It is important figure out influence operation transition RDC. Actually, essential different modes multi-wave structures. In this study, two-dimensional numerical simulations RDC are conducted effect stability and performance A unif...

In CKD, large arteries remodel and become increasingly stiff. The greater pulsatile pressure reaching the glomerulus as a result of increased aortic stiffness could induce renal damage, suggesting that the stiffening and remodeling of large arteries could affect the progression of CKD. We measured carotid-femoral pulse wave velocity, aortic pressure and carotid remodeling and stiffness paramete...

BACKGROUND Endothelial progenitor cells (EPCs) are responsible for angiogenesis and maintenance of microvascular integrity, the number of EPCs is correlated with oxidative stress. Their relation to myocardial dysfunction in patients with type 2 diabetes mellitus (T2DM) is nonetheless unknown. METHODS Eighty-seven patients with T2DM and no history of coronary artery disease were recruited. Tra...

OBJECTIVE Accomplish the first large-scale combat casualty training using multiple-modality hybrid simulation in the Uniformed Services University's one-of-a-kind three-dimensional Wide Area Virtual Environment (WAVE). METHODS 91 first-year medical students (MS1) completed a WAVE training session as part of their Combat Medical Skills course. In teams of 6 students, they treated two combat ca...

This work presents an analytical study of the parametric instability cylindrical panels containing functionally graded porous exposed to static and dynamic periodic axial loads under simply supported boundary conditions. Based on Hamilton’s principle, governing equation motion by using first-order shear deformation theory (FSDT) has been obtained. By applying Galerkin technique, excitation freq...
