Many hospitals do not have a structured process of consent, the attainment of which can often be rather ‘last-minute’ and somewhat chaotic. This is a surprising state of affairs as spinal surgery is a high-risk surgical specialty with potential f

Sixty-six consecutive patients with adolescent idiopathic scoliosis treated by posterior spinal fusion using Harrington distraction compression instrumentation were followed for a minimum of 3 years. Initial surgical correction was satisfactory, but

Dwarf Cepheids (large-amplitude δ Sct variables and SXPhe variables in the GCVS) are late A-type stars near light maximum and early-F stars near light minimum. In the lower part of the instability strip where these stars are found the pulsation cons

Photometry of CY Aqr in the uvby-Beta and VRIC photometric systems has been secured and analyzed. A phase-averaged effective gravity of log geff = 4.04 and effective temperature of 7740 K are found from model-atmosphere grids. The star is metal poor

New photoelectric times of maximum light of the SX Phoenicis variable CY Aquarii are combined with times of maximum light extending over 64 years to determine the long-term period variations. The recent data do not show significant cycle-to-cycle var

In this paper, we consider the zero points of six sets of Stromgren-beta photometry. The color-index system to which our results are referred is a "Hyades-Coma" system composed of photometry by Crawford and Perry (1966, AJ, 71, 206) and Barnes (1960,

CY Aquarii is a Population II dwarf Cepheid that has been observed on a regular basis since 1930. We present evidence from unpublished times of maximum light from Brigham Young University observations secured in the mid-1970s to the present that indi
