Semiaquatic frogs may not breathe air for several months because they overwinter in ice-covered ponds. In contrast to many vertebrates that experience decreased motor performance after inactivity, bullfrogs, Lithobates catesbeianus, retain functional respiratory motor processes following cold-submergence. Unlike mammalian hibernators with unloaded limb muscles and inactive locomotor systems, re...

In order for underwater vehicles to fully realize the potential of utilizing oscillating foils as propulsion mechanisms, it is necessary for the control scheme to be aware of the state of the water environment, especially the vorticity in the water. In this paper, we investigate the problem of estimating the hydrodynamic potentials based on pressure measurement on a submerged body. A relationsh...

Aim:In this study, the results of clinical, ultrasonographic, and laparotomy examinations a five-year-old dairy cow with right abomasal displacement traumatic reticuloperitonitis are presented. Materials Methods: A Holstein who had recently given birth was brought to veterinary teaching hospital history depression, anorexia, constipation, arched backs, bloat. Based on clinical ultrasonographic ...

In this paper a fully Eulerian solver for the study of multiphase flows simulating propagation surface gravity waves over submerged bodies is presented. We solve incompressible Navier-Stokes equations coupled with volume fluid technique modeling liquid phases interface, an immersed body method solid and iterative strong-coupling procedure fluid-structure interaction. The flow incompressibility ...

Fungal cultures were isolated from soil samples collected from the Western Ghats regions of Kerala. Primary screening of isolated strains were done by Sudan black staining method and 15 lipid producing cultures were isolated. The fatty acid profiling of the positive strains were analyzed for docosahexaenoic acid (DHA) production. Selected oleaginous cultures were grown in submerged culture cond...

We describe an implantable patch sensor for monitoring L-glutamate in hippocampal slices in submerged and interface preparations. This patch sensor is prepared by excising the cell membrane in the CA3 region of a hippocampal slice in a submerged preparation, and then implanted in the target neuronal region (CA1) of mouse hippocampal slices. The lifetime of the sensor was 3-8 min for the interfa...

Submerged arc welding process is usually employed for welding of thick workpieces. Quality of submerged arc welded components depends on various factors. Selection of appropriate process parameters for joining metallic components is needed to obtain sound weldment. Many researchers carried out investigations to find out appropriate process conditions to obtain quality submerged arc welded compo...

Submerged arc welding is preferred over other methods of welding because of its inherent qualities like easy control of process variables, high quality, deep penetration, smooth finish, capability to weld thicker sections. Since the development of submerged arc welding process, welding engineers are striving for reduction in welding cost without compromise in the performance of the weld. Flux u...

The main focus of this paper is the motion planning problem for a deeply submerged rigid body. The equations of motion are formulated and presented by use of the framework of differential geometry and these equations incorporate external dissipative and restoring forces. We consider a kinematic reduction of the affine connection control system for the rigid body submerged in an ideal fluid, and...
