what he calls a string of coincidences. A physiologist colleague in Guatemala who happened to have worked with John Vane, then at the Royal College of Surgeons, recommended Moncada to Vane. Once in England, Moncada joined Vane's team, which was then working on the mechanism of action of aspirin and its relationship with prostaglandin synthesis. In 1974, he returned to Honduras to pursue a resea...

The undrained shear strength is a paramount parameter in determining the consistency and ultimate bearing capacity of clay layer. This resistance can be determined by in-situ tests, such as field vane test or laboratory including portable test, triaxial, simple compression penetrometer (i.e. Swedish cone). However, cone are most commonly used geotechnical experts. In this paper, relationships b...

We report microwave emission measurements from an inverted relativistic magnetron comprising an outer cylindrical field emission cathode and an inner coaxial anode with embedded vane resonators. The magnetron operates in the w mode at a frequency of %3.6GHz, and voltages of 1-2MV. The RF power is %500MW.

The modern gas turbine engine requires innovative cooling techniques to protect its internal components from the harsh operating environment typically seen downstream of the combustor. Much research has been performed on the design of these cooling techniques thus allowing for combustion temperatures higher than the melting point of the parts within the turbine. As turbine inlet temperatures an...

Abstract In this article, a numerical investigation of the effect miniaturized five-hole probe downstream transonic low-pressure turbine vane row is presented. First, calibration was performed in uniform flow conditions, as case for any traditional calibration, wide range Mach number, yaw angle, and pitch angle conditions. The on general field throughout segments then evaluated by performing co...

A graph on 2n vertices can be Skolem-labeled if the vertices can be given labels from {1, . . . , n} such that each label i is assigned to exactly two vertices and these vertices are at distance i. Mendelsohn and Shalaby have characterized the Skolem-labeled paths, cycles and windmills (of fixed vane length). In this paper, we obtain necessary conditions for the Skolem-labeling of generalized k...

The flat-hull ship design is an innovative concept that saves costs and speed-up the fabrication of ship. Even though was hydrodynamically inefficient, some shipowners probably experienced issue with its unusual shape disadvantages where drag greater than conventional ships. This paper aimed to improve a vessel using hull vane bow foil reduce resistance. asymmetric NACA 4412 0012 were used for ...
