Intrinsic Geometry of Intersection Curves of Surfaces
ISBN: 9783847322023 / Angielski / Miękka / 2011 / 132 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. This book is motivated by surface-surface intersection problems (SSI) in R3, self-intersection surfaces problem in R3 and three hypersurfaces intersection problems (SSSI) in R⁴. It presents algorithms for computing all the differential geometry properties of Frenet apparatus (t, n, b,κ,τ) of intersection curves of surfaces in R3 for transversal and tangential intersection. The surfaces may be implicit parameterization or parametric parameterization. It is also presents algorithms for computing all the differential geometry properties of intersection curves of Frenet apparatus...

Bioactive Compounds and Extracts of Heteroxenia ghardaqensis
ISBN: 9783659677939 / Angielski / Miękka / 2015 / 104 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. This work introduce a complete study of the the chemical constituents of the Egyptian Red sea soft coral, Heteroxenia ghardaqensis. The chemical study of this coral was occurred depending upon the chromatographic techniques. The structure of the isolated compounds were elucidated by complete spectroscopic analysis. The isolated compounds were studied for their anticancer and antimicrobial activities. Also protective activity of chloroform extract against cadmium-induced adrenal toxicity was evaluated in rats.
