This paper presents a theoretical study on the velocity distribution and the friction factor of boundary layer flows with polymer additives starting from the concept of “stress deficit.” A novel method of order of magnitude analysis is developed, which converts the governing equations of boundary layer flow into a solvable ordinary differential equation, thus the total shear stress distribution...

the twin deficits (budget deficit and current account deficit) have been argued in the economic literature since 1980s. this is a period in which the studies about budget deficit and the current account deficit were significantly increased in the united states. in the economic literature, there are two hypothesis: keynesian hypothesis and ricardian equivalence. the keynesian proposition confirm...

Igo-192. rggg.---The surgical technique of isolation of the blood supply of the gracilis muscle of the dog has been developed for analysis of the oxygen consumption during reactive hyperemia. The time course of the blood flow, A-V oxygen difference and the oxygen consumption follow the same pattern. Immediately after the release of the arterial occlusion, there is an increase in all three value...

This paper presents a battery integrated Power Flow Controller (PFC) which is found effective for the interconnection of several dc microgrids. The configuration offers delicate control over load-flow and also provides way integration Common Energy Storage (CES) to adjacent grids. CES more when both grids have surplus or deficit power compared their individual storage capacity (if any). In this...

the main goal of this research is studying the causative & effect of deficit budget, money offering and inflation rate in iran during 1360-1390. the results in long time indicates that the bulk of money has had positive effect & meaning on inflation rate during that time and alteration of budget deficit of the government has also positive effect on inflation but by meaningless impress, in other...

A 1:20 scaled three-bladed horizontal-axis tidal turbine is positioned in the wake flows of two wall-mounted obstacles: a square cylinder and combination cube front cylinder. The turbine's induction effects are examined with upstream flow measurements without operating at its optimal regime. In (at 0.07D hub extremity, D diameter), mean axial vertical velocities modified by whatever complexity ...
