Aims. To detect line effects using spectropolarimetry in order to find evidence of rotating disks and their respective symmetry axes in T Tauri stars. Methods. We used the IAGPOL imaging polarimeter along with the Eucalyptus-IFU to obtain spectropolarimetric measurements of the T Tauri stars RY Tau (two epochs) and PX Vul (one epoch). Evidence of line effects showing a loop on the Q−U diagram f...

Most lumbar disk herniations improve over time with or without medical treatment. Disk herniations and annular tears may not be symptomatic and are shown to exist in patients without any symptoms. In some patients, chronic low back pain may result from the syndrome of internal disk disruption. Treatment of chronic pain of diskal cause can be challenging and have varying results in terms of succ...

Archibald [1] analyzed the performance of a squeeze film between various geometrical configurations. Later on Wu [2, 3] investigated a squeeze film behavior for mainly, two types of geometries namely, annular and rectangular. Prakash and Viz [4] developed some aspects of the analysis incorporated in Wu [2, 3] and obtained the load carrying capacity ultimately leading to time height relation for...

We present kinematic measurements of the thick and thin disks in two edge-on galaxies. We have derived stellar rotation curves at and above the galaxies’ midplanes using Ca ii triplet features measured with the GMOS spectrograph on Gemini North. In one galaxy, FGC 1415, the kinematics above the plane show clear rotation that lags that of the midplane by ∼20-50%, similar to the behavior seen in ...

Following stepping in-place on the surface of a rotating circular treadmill, a subject attempting to step in-place or walk in a straight line across the floor without vision will rotate relative to space. This adaptation, termed podokinetic after-rotation (PKAR), transfers to backward walking following forward walking on the rotating disk. We asked whether adaptation obtained during stepping in...

The articulations of the spinal motion segment, the intervertebral disk, and the zygapophyseal joints, inevitably undergo age-related changes. This article focuses on the intervertebral disk, specifically when fissures sufficiently weaken the posterior annulus so as to allow herniation of nuclear material into the outer annular structure as a contained protrusion or breach the annulus and pass ...

in order to simulate the rotating disk contactor all hydrodynamic parameters, dispersed phase hold-up, characteristic velocity, mean drop size, drop size distribution, axial mixing and mass transfer have been taken into account. mechanisms of mass transfer (stagnant, circulating, oscillating drops) were used in this study. column height found from effect of mean drop size and drop size distribu...

The latest studies of massive star evolution indicate that an initially rapidly rotating star with sufficiently low metallicity can produce a rapidly rotating, massive stellar core that could be a progenitor of long-soft gamma-ray bursts (LGRBs). Motivated by these studies, we follow the collapse of a rapidly rotating massive stellar core to a ’collapsar’ black hole (BH) surrounded by a massive...
