Nutrition and Cancer: Dr. Douglas Wilson - Honoured
Historical, current and future aspects of the potential value of ‘phyto-oestrogens’ and lifestyle in lowering the risk of endocrine cancer, and high-lighting the crucial importance of global policy makers in providing the means for a healthier diet, is the purport of this paper. Early studies in Chiang Mai, Thailand, and S.W. Australia demonstrated the potential value of oestrogen-like dietary ...
متن کاملCorpses and maniacs: the loves of Dr James Douglas.
I t was a fine day in the dead of winter, 1826, when a young doctor and his wife arrived in Quebec city, Que, in a horse-drawn sleigh, galloped around the city a few times, liked the look of it, and decided to stay for the rest of their lives. The next day they sold their horse and started looking around for real estate. A few days later they bought a house. Dr James Douglas was a refugee and a...
متن کاملGeneralized 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.
متن کاملOn 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.
