1Stokes flow before plane boundary with mixed stick-slip boundary conditions显示文摘A general theorem for the Stokes flow over a plane boundary with mixed stick-slip boundary conditions is established.This is done by using a representation for the velocity and pressure fields in the three-dimensional Stokes flow in terms of a biharmonic function and a harmonic function.The earlier theorem for the Stokes flow due to fundamental singularities before a no-slip plane boundary is shown to be a special case of the present theorem.Furthermore,in terms of the Stokes stream function,a corollary of the theorem is also derived,providing a solution to the problem of the axisymmetric Stokes flow along a rigid plane with stick-slip boundary conditions.The formulae for the drag and torque exerted by the fluid on the boundary are established.An illustrative example is given.N.AKHTAR G.A.H.CHOWDHURY S.K.SEN 2011Applied Mathematics and Mechanics(English Edition)2011,32,6:0
2STOKES FLOW DUE TO FUNDAMENTAL SINGULARITIES BEFORE A PLANE BOUNDARY显示文摘A representation for the velocity and pressure fields in three-dimensional Stokes flow was presented in terms of a biharmonic function A and a harmonic function B.This representation was used to establish a general theorem for the calculation of Stokes flow due to fundamental singularities in a region bounded by a stationary no-slip plane boundary.Collins’s theorem for axisymmetric Stokes flow before a rigid plane follows as a special case of the theorem.A few illustrative examples are given to show its usefulness.N.Aktar F.Rahman S.K.Sen 2004Applied Mathematics and Mechanics(English Edition)2004,25,7:0
3由烃产生赖氨酸的节杆菌与小球菌的新菌株显示文摘利用生物自显影技术,从263株烃利用菌中分离到24株赖氨酸产生菌。研究了两株有价值的分离菌的形态、培养及生物化学特性。其中一株经鉴定为球形节杆菌(Arthrobacter globiformis)。S.K.Sen M.Chatteree S.P.Chatterjee 唐任天 1982氨基酸和生物资源1982,10,4:0
4New Strains of Arthrobacter and Micrococcus Producing Lysine from Hydrocarbon显示文摘Following the bioautographic te-chnique, 24 lysine producing microor-ganisms have been isolated from amongthe 263 hydrocarbon utilisers. Morphological, cultural and biochemicalcharacters of two promising isolates,have been studied. One of them iden-tified as Arthrobacter globiformis andthe other as Micrococcus varians, pro-duce 3.4 and 2.6 g lysine per litreof medium.S.K.Sen M.Chatterjee S.P.Chatterjee 1982氨基酸和生物资源1982,10,4:0
