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 ...

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...

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.
