austenite is a semi-stable phase in most stainless steels that deforms to martensite under md30 and forms martensitetype ά and ε due to the deformation in the steels. since the distribution of strain induced martensite plays animportant role in achieving desired properties, the main objective of the present work is to model martensitedistribution of ά during cold rolling using finite element me...

introduction abnormal neural impulses in the nervous system may lead to various diseases and disabilities. high frequency alternating currents (hfac) has been used to block the propagation of such impulses and improve the symptoms or disabilities. the technique is safe, reversible, and relatively selective, and its reliability, the optimum stimulation parameters, and elimination of the onset re...

among the all parameters affecting the performance of a downhole de-oiling hydrocyclone, the investigation of internal flow field deserves more attempts especially in the petroleum industry. in this study, the effects of inlet flow rate, inlet oil volume fraction, and oil droplet diameter on the separation efficiency and pressure drop ratio have been investigated along the hydrocyclone body. al...

computational fluid dynamics (cfd) simulations of gas-solid flow through a positive low-pressure pneumatic conveyor were performed using eulerian-eulerian framework. pressure drop in pneumatic conveying pipelines, creation and destruction of plugs along the horizontal and vertical pipes, effect of 90° elbows and u-bends on cross-section concentrations, and rope formation and dispersion were num...

dense medium cyclone is a high capacity device that is widely used in coal preparation. it is simple in design but the swirling turbulent flow, the presence of medium and coal with different density and size fraction and the presence of the air-core make the flow pattern in dmcs complex. in this article the flow pattern simulation of dmc is performed with computational fluid dynamics and fluent...

Precise definitions of elliptic islands and chaotic seas are difficult to give. Models for chaotic seas are rare in theory and practice. A few results on the dynamics in the chaotic region are available [1-2-3-4-6-7-9-15-16]. Some topological characterizations of elliptic islands in a chaotic sea are available in [5-8-11-12-17-18-19]. One of the techniques uses rotation numbers [13-14]. There a...

Population 56 consecutive AIS patients from our prospective database (39 female; age 13±1, Cobb 21±4° ; ATR 11±4° ): 28 patients (19 females; age 13±1; TRACE score 6; Cobb angle 22±4° ; ATR 12±4° , Risser 0-3) treated by Spinecor 20/24 hours; 28 patients (20 females; age 13±1; TRACE score 5; Cobb angle 20±4° ; ATR 9±3° , Risser 0-3) treated by SEAS exercises.The short term results of treatment ...

The Southern Ocean exerts a profound influence on the functioning of the Earth System, in part because its location and unique bathymetric configuration enable direct linkages to the other major ocean basins (Ganachaud and Wunsch, 2000; Lumpkin and Speer, 2007). It is the site of the world's largest current system, the Antarctic Circumpolar Current (ACC), which transfers waters and climatically...

The central factor of the period of world history through which we are now passing is the rivalry between England and Germany. This rivalry must inevitably lead to an armed struggle between them, the issue of which will, in all probability, prove fatal to the vanquished side. The interests of these two powers are far too incompatible, and their simultaneous existence as world powers will sooner...

a r t i c l e i n f o Strategic Environmental Assessment (SEA) is a tool that can facilitate sustainable development and improve decision-making by introducing environmental concern early in planning processes. However, various international studies conclude that current planning practice is not taking full advantage of the tool, and we therefore define the paradox of SEA as the methodological ...
