We investigate numerically and semi-analytically the collapse of low-mass, rotating prestellar cores. Initially, the cores are in approximate equilibrium with low rotation (the initial ratio of thermal to gravitational energy is α0 ≃ 0.5, and the initial ratio of rotational to gravitational energy is β0 = 0.02 to 0.05). They are then subjected to a steady increase in external pressure. Fragment...

BACKGROUND We report experience with patients presenting with a specific combination of symptoms: unilateral sciatica, unilateral sensibility loss in the dermatomes S1 to S5 (hemi-saddle) and subjective micturation problems secondary to ruptured lumbar disc. Because of its similarities with a cauda equina syndrome, this combination of symptoms was thought to be a unilateral cauda equina syndrom...

ABSTRACT We present the spectro-timing analysis of black hole binary system GX 339?4 using AstroSat data extracted at beginning outbursts in 2017 and 2019. The joint spectral fitting Large Area X-ray Proportional Counter (LAXPC) Soft Telescope (SXT) revealed that source was a faint low/hard state for both 2019 observations, with nearly equal photon indexes ?1.57 ?1.58 Eddington ratios, L/LEdd, ...

The authors developed a three-dimensional seismic isolation system to ensure performance in the vertical and horizontal directions. This is required for large-scale disc spring achieve both support functions. Additionally, two methods are required: one control variance of restoring force, other predict using response analysis. paper describes an optimal combination method springs absorb caused ...

background the purpose of this study was to evaluate the characteristics, management, and outcomes of disc battery ingestion in children. methods we reviewed the medical records of children admitted to mofid children's hospital due to disc battery ingestion from january 2006 to january 2010. clear history, clinical symptoms and results of imaging studies revealed diagnosis of disc battery inges...

purpose : to investigate the impact of socioeconomic factors on presenting severity of glaucoma methods : in a cross-sectional study at farabi eye hospital, and during 12 months study period, 258 patients with newly diagnosed glaucoma were enrolled and socioeconomic status of the patients were evaluated. results : lower socioeconomic score was associated with higher intraocular pressure (r=-0.3...

background enterococci have emerged as more virulent and multidrug-resistant in community and hospital settings. the emergence of vancomycin resistant enterococci (vre) in hospitals has posed a serious threat to public health. the widespread use of antibiotics to treat vre infections has resulted in the development of resistant forms of these organisms. conclusions among the nanoparticles, zno ...

Background & Importance: Disc herniation is defined as the prolapsed of material disc into the spinal canal. If the disc fragment is free in spinal canal, it is called sequestration disc fragment. Occasionally, alteration in sequestration disc fragment makes the diagnosis of the disc herniation, challenging. Case Presentation: We reviewed a rare case of the cervical sequestrated disc...

  Abstract   Background: Far lateral discal herniation is an uncommon disorder and is difficult   to assess by physical examination alone. This study is designed to define clinical and   epidemiological findings and to establish the indications of surgical and medical treatment for FLLDH.   Methods: Between 2000 and 2005, a total of 2035 patients with lumbar disc herniation   underwent surgical...

Stars born on near-circular orbits in spiral galaxies can subsequently migrate to different due interactions with non-axisymmetric disturbances within the disc such as bars or arms. This paper extends study of migration examine role external influences using example interaction Sagittarius dwarf galaxy (Sgr) Milky Way (MW). We first make impulse approximation estimates characterize influence Sg...
