| 1 | A FINITE ELEMENT SOLVER FOR NAVIER-STOKES EQUATIONS VIA VORTICITY AND VELOCITY显示文摘The incompressible Navier Stokes equations are solved via variables of vorticity and velocity. Firstly, a rigorous variational framework with the equivalence between the velocity pressure and the vorticity velocity formulations is presented in a Lipschitz domain. Next, a class of Galerkin finite element approximations of the corresponding variational form is introduced, and a convergence analysis is given for the Stokes problem. Finally, an iterative finite element solver for the Navier Stokes problem is proposed. | Zhu Jiang Abimael F D Loula Laboratório Nacional de Computaco Científica, MCT,Av Getúlio Vargas 333, 25651 070 Petrópolis, RJ, Brazil | 2001 | Transactions of Nanjing University of Aeronautics and Astronautics2001，18，z1： | 0 |
| 2 | Possible Role of the Submandibular Gland in the Development of Obesity in Mice显示文摘The possible role of submandiblular glands (SMG) in the development of obesity was studied in two types of genetically obese mice, ob/ob and yellow Ay: Obesity is caused by hyperplasia followed by hypertrophy in ob/ob mice and mainly by hypertrophy in Ay mice.The histological features of SMGs exhibited clear sexual dimorphism in both mice similarto lean controls. The SMGs of ob/ob mice was smaller in size and had smaller granular convoluted tubular portions than lean controls, while the SMGs of Ay mice did not differ from lean controls. Sialoadenectomy before and after development of obesity gCnerally reduced the gain of body weights in both sexes of Ay mice but not in ob/ob mice. The content of epidermal growth factor (EGF) in the SMGs was higher in Ay mice and lower in ob/ob mice than their controls. The possible role of EGF in the SMGs in the development of obesity is | JUNKO YAMASHITA SHIN-ICH HAYASHI YUKIO HIRATA AND MASAYASU MIYAJIMA(Department of Biochemistry 2, The Jikei University School of Medicine,Tokyo 105 Japan Department of Anatomy, School of Medicine,University of the Ryukyus.
