Motivated by the low-collisionality of gas accreted onto black holes in Sgr A* and other nearby galactic nuclei, we study a family of 2D advective accretion solutions with thermal conduction. While we only impose global inflow, the accretion flow spontaneously develops bipolar outflows. The role of conduction is key in providing the extra degree of freedom (latitudinal energy transport) necessa...

objective and aims intrauterine devices (iuds) are placed in the uterine cavity with the objective of providing long-term contraception, mainly by preventing fertilization. in this research has been tried to show that method of iud insertion is effective to decrease complications’ incidence . rotating withdrawal technique is presenting, has been using for this purpose. design and setting this h...

The relationship between system condition and signal-to-noise ratio (SNR) in reconstructed Stokes parameter images is investigated for rotating compensator, variable retardance, and rotating analyzer Stokes vector (SV) polarimeters. A variety of optimal configurations are presented for each class of systems. The operation of polarimeters is discussed in terms of a four-dimensional conical vecto...

This paper presents finite element analysis of the strength of roadheaher conical picks. Failure forms of conical picks are investigated, and the FE model of conical pick is established based on ANSYS. The static analysis is carried out according to the load calculated by empirical formula and the deformation map and stress distribution are obtained. The results show that the maximum stress of ...

The Taguchi method of experimental design was employed in this study to scrutinize the impact welding processing factors, including rotating speed, travelling and pin profile on ultimate tensile strength, microhardness, strength Friction Stir Welded AA 8052 joint. S/N values for each process specification were calculated using an orthogonal array L9 design. 1150 rpm 28.5 mm/min greatest evaluat...
