In order to study the axial compression performance of FRP (fiber reinforced polymer)-concrete-steel solid columns (FCSSC), nonlinear analysis program FCSSC was compiled in this paper. The verified by existing tests, and impacts tube thickness, steel outer radius tube, strength concrete were examined. outcomes showed that calculated results agreed with experimental results. It demonstrated way ...

A component-based simulation tool for modeling the steady state performance and cost of vapor compression systems has been developed. Features of the simulation software include component inter-changeability, charge management, and built-in multi-objective optimization routines. The simulation tool is capable of optimizing for a variety of performance or economic variables by varying any compon...

In small vessels blood is usually treated as a Newtonian fluid down to diameters of ~200 μm. We investigate the flow of red blood cell (RBC) suspensions driven through small tubes (diameters 10-150 μm) in the range marking the transition from arterioles and venules to the largest capillary vessels. The results of the simulations combined with previous simulations of uniform shear flow and exper...

SUMMARY The application of a long stroke isentropic free piston compressor as the energy source for an intermittent M = 6.85 hypersonic wind tunnel is described. The advantages of comparatively long running times of up to 0.5 s and uniform reservoir conditions at up to 90 bar and 600 K are discussed. Particular problems arising from the long stroke compression associated with both viscous flow ...

In this paper we introduce a new compression technique for 2D vector fields which preserves the complete topology, i.e., the critical points and the connectivity of the separatrices. As the theoretical foundation of the algorithm, we show in a theorem that for local modifications of a vector field, it is possible to decide entirely by a local analysis whether or not the global topology is prese...

In the present study, expression of pituitary adenylate cyclase-activating polypeptide (PACAP) in rat dorsal root ganglion (DRG) neurons and sciatic nerve following experimental sciatic nerve compression was studied with the use of quantitative immunohistochemistry and in situ hybridization. Previously, we have investigated changes in PACAP expression after nerve transection and, here, the far ...

OBJECTIVES (1) Present a unique case of partial necrosis of the dorsal tongue caused by an endotracheal tube; (2) highlight the importance of verifying proper endotracheal tube positioning during cases requiring prolonged intubation. METHODS Case report and literature review. RESULTS A 50 year-old man underwent total thyroidectomy and bilateral lymphadenectomies for papillary thyroid carcin...
