Ovarian luteinized thecoma with sclerosing peritonitis in an adult woman treated with leuprolide and toremifene in complete remission at 5 years.
Gynecologic oncology, 2005Co-Authors: Roberto Bianco, Gaetano De Rosa, Stefania Staibano, Pasquale Somma, Angelo Raffaele BiancoAbstract:Abstract Background. Luteinized thecoma of the ovary associated with sclerosing peritonitis is a rare pathologic condition without a standard strategy of treatment. Case. We present the case of an ovarian luteinizing sclerosing thecoma in a 39-year-old woman. The patient underwent three laparotomic operations for subocclusive symptoms, revealing in both occasions the presence of sclerosing peritonitis, with large abdominal masses, including cysts containing Clear Fluid. Treatment with toremifene 20 mg/day and leuprolide resulted in a dramatic improvement of the performance status and complete remission of all the abdominal lesions. After 60 months follow-up, the patient is still disease-free. Discussion. Antiestrogens plus LHRH agonists might be a noninvasive, effective and well-tolerated therapy for sclerosing peritonitis in patient operated for luteinized thecomas.

Do Isoflux Boundary Conditions Inhibit Oscillatory Double-Diffusive Convection?
Transport in Porous Media, 2016Co-Authors: D A Nield, A V KuznetsovAbstract:We formulate a problem describing the onset of multi-diffusive convection in a horizontal porous layer. Our formulation collapses to a Clear Fluid case in a special limit. We study this problem, analytically and numerically, for the case of two diffusing components. We concentrate on the case when the boundary conditions at the two horizontal walls approach isoflux conditions and thus the critical wave number approaches zero. We investigate how the reduction in the critical wave number affects oscillatory instability.

the effect of a transition layer between a Fluid and a porous medium shear flow in a channel
Transport in Porous Media, 2009Co-Authors: D A Nield, A V KuznetsovAbstract:Flow in a three-layer channel is modeled analytically. The channel consists of a transition layer sandwiched between a porous medium and a Fluid Clear of solid material. Within the transition layer, the reciprocal of the permeability varies linearly across the channel. The Brinkman model is used for the momentum equations for the porous medium layer and the transition layer. The velocity profile is obtained in closed form in terms of Airy, exponential, and polynomial functions. The overall volume flux and boundary friction factors are calculated and compared with values obtained with a two-layer model employing the Beavers–Joseph condition at the interface between a Darcy porous medium and a Clear Fluid.

numerical modeling of turbulent flow in a composite porous Fluid duct utilizing a two layer k e model to account for interface roughness
International Journal of Thermal Sciences, 2004Co-Authors: A V KuznetsovAbstract:Abstract This paper is aimed at investigating the effect of roughness of the porous/Fluid interface on turbulent convection heat transfer in composite porous/Fluid ducts. It is expected that in many cases the effect of interface roughness on convection may be more significant than the effect of possible flow turbulization in the porous region. The analysis of appropriate dimensionless parameters shows that in many practical situations even if the flow in the Clear Fluid region is turbulent, the flow in the porous region remains laminar. The problem is thus reduced to matching the turbulent flow solution in the Clear Fluid region with the laminar flow solution in the porous region at the rough interface. It is shown that roughness of the porous/Fluid interface significantly impacts turbulent flow in the Clear Fluid region as well as overall heat transfer in the duct.

influence of the stress jump condition at the porous medium Clear Fluid interface on a flow at a porous wall
International Communications in Heat and Mass Transfer, 1997Co-Authors: A V KuznetsovAbstract:Abstract This paper presents an analytical solution for the steady fully developed Fluid flow in a composite region, which is partly filled with a porous medium and partly with a Clear Fluid. The Brinkman-Forchheimer equation is utilized to model the flow in a porous region. Different from the previous investigations, the stress jump boundary condition suggested by Ochoa-Tapia and Whitaker is used at the porous medium/Clear Fluid interface.

analytical investigation of the Fluid flow in the interface region between a porous medium and a Clear Fluid in channels partially filled with a porous medium
Flow Turbulence and Combustion, 1996Co-Authors: A V KuznetsovAbstract:In this paper analytical solutions for the steady fully developed laminar Fluid flow in the parallel-plate and cylindrical channels partially filled with a porous medium and partially with a Clear Fluid are presented. The Brinkman-extended Darcy equation is utilized to model the flow in a porous region. The solutions account for the boundary effects and for the stress jump boundary condition at the interface recently suggested by Ochoa-Tapia and Whitaker. The dependence of the velocity on the Darcy number and on the adjustable coefficient in the stress jump boundary condition is investigated. It is shown that accounting for a jump in the shear stress at the interface essentially influences velocity profiles.
