ECHO CARDIOGRAPHY: Was performed on the Toshiba SSH 160A, 2 Dimensional colour doppler echocardiography instrument with transducer frequency at 2.5MHz. The 2 Dimensional picture for the valve morphology was studied. The assessment of MR was then done by the colour Doppler echocaridiography at velocity mode using a 300 sector angle at pulse repitition frequency of 3KHz, wall lter at 600Hz and s...

Abstract We discuss the star-disk electric circuit for a young stellar object (YSO) and calculate the expected torques on the star and the disk. We obtain the same disk magnetic field and star-disk torques as given by standard magnetohydrodynamic (MHD) analysis. We show how a short circuit in the star-disk electric circuit may produce a magnetically-driven jet flow from the inner edge of a disk...

Spatio-temporal evolution of a small localized meander on a Gulf Stream-type baroclinically unstable jet over a topographic slope is investigated numerically using a threedimensional, primitive equation model. An unperturbed jet is prescribed by a potential vorticity front in the upper thermocline overlaying intermediate layers with weak isentropic potential vorticity gradients and a quiscent b...

We report new radio continuum observations with an angular resolution of 2 ′′ .1 at 1.4 GHz (20 cm) and 0 ′′ .28 at 8.4 GHz (3.6 cm), of the barred galaxy NGC 3367. In the map at 1.4 GHz, the central nuclear region connects to the SW lobe, with a projected structure of at a position angle of P.A.∼ 230 • , forming a jet-like structure. The map at 8.4 GHz shows a compact unresolved source (smalle...

We have performed a first fully 3-D GRMHD simulation with Schwarzschild black hole with a free falling corona. The initial simulation results show that a jet is created as in the previous simulations using the axisymmetric geometry with the mirror symmetry at the equator. However, the time to generate the jet is longer than in the 2-D axisymmetric simulations. We expect that due to the addition...

Experimental investigation has been carried out towards understanding the complex fluid dynamics involved in the interaction of vortical structures with zero pressure gradient boundary layer. A laminar boundary layer is produced on the flat plate placed in the water flume and the synthetic jet actuator is deployed on top of the plate at a definite distance from the leading edge. The synthetic j...

The breakup of a millimetre size buoyantly rising bubble encountering a horizontal plane turbulent jet is experimentally investigated using high-speed shadowgraphy and acoustic techniques. The bubble diameter to jet height ratio is 0.75 and the jet height based Reynolds number is 4000. The high-speed imaging was recorded at 7 kHz simultaneous with hydrophone output at 100 kHz. Bubble breakup ev...

We present the deepest yet radio image of the Galactic jet source, SS 433, which reveals over two full precession cycles (> 2×163 days) of the jet axis. Systematic and identifiable deviations from the traditional kinematical model for the jets are found: variations in jet speed, lasting for as long as tens of days, are necessary to match the detailed structure of each jet. It is remarkable that...
