BACKGROUND Excessive intravenous fluid prescription may play a causal role in postoperative complications following major gastrointestinal resectional surgery. The aim of this study was to investigate whether fluid and salt restriction would decrease postoperative complications compared with a more modern controlled liberal regimen. METHODS In this observer-blinded single-site randomized clin...

The alternating current electroosmotic flow of a non-Newtonian power-law fluid is studied in a circular microchannel. A numerical method is employed to solve the non-linear Poisson-Boltzmann and the momentum equations. The main parameters which affect the flow field are the flow behavior index, the dimensionless zeta potential and the dimensionless frequency. At very low dimensionless frequenci...

We introduce a finite volume scheme for the two-dimensional incompressible Navier-Stokes equations. We use a triangular mesh. The unknowns for the velocity and pressure are respectively piecewise constant and affine. We use a projection method to deal with the incompressibility constraint. We show that the differential operators in the Navier-Stokes equations and their discrete counterparts sha...

Modern field-theoretic simulations of complex fluids and polymers are constructed around a particle-to-field transformation that brings an inverse potential u−1 in the model equations. This has restricted application framework to systems characterized by relatively simple pairwise interatomic interactions; for example, excluded volume effects treated through use δ-function interactions. In this...

We consider a finite volume scheme for the two-dimensional incompressible Navier-Stokes equations. We use a triangular mesh. The unknowns for the velocity and pressure are respectively piecewise constant and affine. We use a projection method to deal with the incompressibility constraint. The stability of the scheme has been proven in [15]. We infer from it its convergence. Mathematics Subject ...

To the Editor: We read with interest the excellent article of Daugas et al [1] on HAART-related nephropathies and we would like to clarify several points. There has been no case report of Fanconi syndrome (FS) related to reverse transcriptase inhibitors (RTIs) except one induced by didanosine [2]. Actually, the suspected case of nevirapine-induced FS was largely related to lactic acidosis rathe...

We have previously shown that capsaicin nasal challenge in subjects with allergic rhinitis produces a dose-dependent increase in the albumin content of nasal lavage fluids. In the present set of studies, we determined whether this observation represents plasma extravasation that is neuronally mediated. To evaluate whether glandular secretions contribute to the albumin increase in nasal lavage f...
