In this paper, we prove that a non-Riemannian isotropic Berwald metric or a non-Riemannian (α,β) -metric admits no concurrent vector fields. We also prove that an L-reducible Finsler metric admitting a concurrent vector field reduces to a Landsberg metric.In this paper, we prove that a non-Riemannian isotropic Berwald metric or a non-Riemannian (α,β) -metric admits no concurrent vector fi...

Background & Aims: Endothelin_1 secreted by endothelial cells has been identified as the strongest vascular constrictor. The aim of the present study was to investigate the role of concurrent training on plasma concentration of endothelin_1 and its relationship with blood pressure of old women. Methods: A total of 20 menopause women (Mean age: 67.47±5.92 years, mean body length: 152.92±7.52cm, ...

the purpose of this study was to investigate the interference effect of concurrent strength and endurance training on maximum strength and vo2max in non-athletes. for this purpose, 34 sedentary healthy men (mean age 22±1.18 years, height 173.61±6.48 cm, and weight 56.13±8.50 kg) voluntarily participated in this study. initially, subjects were randomly assigned to one of four training groups: st...

desmoplastic small round cell tumor is a rare malignant tumor that occurs primarily in young males. here, a case of small round cell tumor in an adult male successfully treated with a curative concurrent chemoradiotherapy is presented. a 58-year-old man had an intrapelvic tumor. surgical resection was attempted, but the tumor was unresectable. needle biopsy was performed and the diagnosis was s...
