| 1 | Inflammatory bowel disease in Estonia:a prospective epidemiologic study 1993-1998a显示文摘INTRODUCTIONThe incidence of ulcerative colitis (UC) and Crohn,s disease (CD)in Estonia 1993-1998 was investigated prospectively .The mean annual incidence of UC was 1.7 per 100 000,and that of CD1.4 per 100 000.This population-based study showed much lower incidence of UC and CD than those reported for western and northern Europe . | Riina Salupere Docent of Gastroenterology,Department of Internal Medicine University of Tartu,Estonia | 2001 | World Journal of Gastroenterology2001，7，3： | 13 |
| 2 | Three-Dimensional Simulation of Nonstationary Flow Phenomena in 'Last Stage-Exhaust Hood'Compartment显示文摘Three-dimensional nonstationary model of aerodynamical interaction of turbine stage and exhaust hood is realized, based on nonstationary 3D codes for calculation of inviscid transonic flow through stage[3] and exhaust hood[4] which consist of diffuser and space under casing. The codes are built with the use of the explicit Godunov’s 2nd order difference scheme. Some results of flow simulation through the compartments 'stage-exhaust hood,' 'stage-exhaust axial-radial diffuser' for wide range of volumetric flow rates are represented. | V.G.
