ABSTRACT We model Pop III star formation in different FUV and X-ray backgrounds, including radiation feedback from protostars. confirm previous results that a moderate background increases the number of systems per unit cosmological volume, but masses multiplicities system are reduced. The stellar mass function also agrees with results, we outward migration stars within protostellar discs. find...

Degeneration of the intervertebral discs (IVD) is a leading cause of neck and low back pain. Degeneration begins in the central nucleus pulposus region, leading to loss of IVD osmotic properties. Regeneration approaches include administration of matrix-mimicking scaffolds, cells and/or therapeutic factors. Cell-targeting strategies are likely to improve delivery due to the low cell numbers in t...

purpose: to report a case who had optic disc duplication, a rare congenital disorder characterized by two well-defined discs in one eye. case report: a 19 months-old child presented with unilateral epiphora in the right eye since birthday. the right eye was smaller than the left eye and mild ptosis was apparent. nasolacrimal duct probing was performed under general anesthesia. the examination r...

Foraminal disc herniation at the C2–3 level is a very rare entity, for which consensus treatment protocol has not been established. This case report explains that unilateral biportal endoscopic foraminotomy effective, minimally invasive, and safe procedure this condition. A 62-year-old woman presented to our clinic with complaints of 6-week history posterior axial neck pain sudden onset hypoest...

a woman presenting with severe right lower quadrant (rlq) abdominal pain is presented here. she was evaluated for all usual cause of such pain. laboratory tests and abdominal and pelvic sonography was normal. mri revealed l1-l2 disc herniation.

We analyze the first cosmological simulations that recover the fragmentation of high-redshift galactic discs driven by cold streams. The fragmentation is recovered owing to an AMR resolution better than 70 pc with cooling below 10K. We study three typical star-forming galaxies in haloes of ∼ 5 × 10M⊙ at z ≃ 2.3, when they were not undergoing a major merger. The steady gas supply by cold streams...

The potential to sequester carbon by tree species in tropical regions such as Bangladesh is promising regard sequestration (CS) potentiality and reducing CO2 emissions. This study focuses on perennial within 488 hectares of Agricultural University (BAU) assess the CS produce a C stock map for BAU. To compute green dry weight, weight tree, simplified methodology from National Computational Scien...

Thirty-seven patients with extensive acetabular defects due to loose implants had revisions with uncemented components, the acetabulum being augmented with homograft bone. In six of these, a histological study of graft incorporation was made. At a mean follow-up of 1.5 years 34 patients were free of pain and 35 could walk for 30 minutes or longer. No graft had obviously sequestrated. Two compon...
