Internal waves occur at a variety of temporal and spatial scales and are mechanisms by which momentum, energy, nutrients and biota are transported in lakes, estuaries and coastal oceans. In stratified systems, accurate prediction of water quality effects requires modeling internal wave evolution and propagation. Lake, estuary, and coastal ocean models typically apply the hydrostatic approximati...

where an denotes a vertical acceleration of the fluid, e.g., due to gravity. This formulation can be derived from the NS equations by, most importantly, assuming a hydrostatic pressure along the direction of gravity. Interested readers can find a detailed derivation of these euqations in Section A. In the following sections we will first explain how to solve these equations with a basic solver,...

Disposable materials enjoy annually steady growth in volume in the field of medical applications as surgical gowns, isolation gowns, and medical drapes which impede cross contamination from reusable protective apparel in a hospital. There are four levels of liquid barrier performance according to the American National Standard/Association for the Advancement of Medical Instrumentation (ANSI/AAM...

BACKGROUND Autoclaving, heat, irradiation or chemical detergents are used to disinfect autografts, allografts and biomaterials for tissue reconstruction. These methods are often associated with deterioration of mechanical, physical, and biological properties of the bone grafts and synthetic implants. High hydrostatic pressure has been proposed as a novel method preserving biomechanical and biol...

Magnetic liquid double suspension bearing (MLDSB) is composed of an electromagnetic system and hydrostatic its capacity stiffness can be greatly improved. It very suitable for occasions medium speed, heavy load, starting frequently. Due to the gyroscopic effect interference between supporting system, space state rotor affected operation stability MLDSB reduced greatly. Therefore, coupling featu...

we present a 23-year-old man with distal humerus osteoid osteoma referring to our hospital with pain and progressive stiffness. the patient has been suffering from the disease for two years without a certain diagnosis. the radiographies of elbow did not reveal the pathology but further ct scan and mri studies demonstrated the tumor. the en block resection of the tumor resolved the pain immediat...
