Abstract Aim To analyze the safety, feasibility, and effectiveness of a systematized laparoscopic transabdominal preperitoneal approach for recurrent inguinal hernia. Material & Methods A retrospective observational analysis database between July 2012 2022. Inclusion: all patients with standard tapp to treat The variables were compared our results in primary hernias: finding (cause type usi...

We report on high spectral resolution observations of five damped Lyman-α absorbers: zabs = 3.0248 toward Q 0347–383, zabs = 2.1411 and 2.8112 toward Q 0528–250, zabs = 2.6184 toward Q 0913+072, and zabs = 2.5226 toward Q 1213+093. Line velocity profiles and heavy element abundances are discussed. Nitrogen is found to have abundances less than silicon in the systems toward Q 0347−383, Q 0913+07...

Received ; accepted – 2 – ABSTRACT We report the detection of velocity variations in the pulsating sdB star, PG 1605+072. Oscillations are detected at the same frequencies found from photom-etry and have amplitudes of up to 14 km s −1 for Hβ. The strongest oscillation found in previous photometric observations is not evident in our spectroscopy or photometry, and may be absent due to beating of...

We present time-series spectroscopy and multi-band photometry of the sdBV PG1605+072 carried out simultaneously at the Calar Alto 2.2m and 3.5m telescopes. The periodogram analysis of the radial velocity curves reveals three frequencies at 2.078, 2.756, and 1.985 mHz for Hβ and at 2.076, 2.753, and 1.978 mHz for Hγ . The corresponding radial velocity amplitudes are 12.7, 8.0, and 7.9 km/s for H...
