Generalized Douglas-Weyl Finsler Metrics

In this paper, we study generalized Douglas-Weyl Finsler metrics. We find some conditions under which the class of generalized Douglas-Weyl (&alpha, &beta)-metric with vanishing S-curvature reduce to the class of Berwald metrics.

On Special Generalized Douglas-Weyl Metrics

In this paper, we study a special class of generalized Douglas-Weyl metrics whose Douglas curvature is constant along any Finslerian geodesic. We prove that for every Landsberg metric in this class of Finsler metrics, ? = 0 if and only if H = 0. Then we show that every Finsler metric of non-zero isotropic flag curvature in this class of metrics is a Riemannian if and only if ? = 0.

Ovarian cyst impacted in the pouch of Douglas at 20 weeks' gestation managed by laparoscopic ovarian cystectomy: a case report

INTRODUCTION The frequency of ovarian cysts in pregnancy is reported to be 1 in 1000 pregnancies. Laparoscopic ovarian cystectomy has been described in the literature as case series but this is the first case where an ovarian cyst at 20 weeks' gestation impacted in the pouch of Douglas was managed exclusively by laparoscopy. CASE PRESENTATION A 31-year-old primigravida woman was diagnosed as ...
