A simple globular-shaped liquid (octamethylcyclotetrasiloxane, OMCTS) was placed between two solid plates at variable spacings comparable to the size of this molecule and the linear shear viscoelasticity of the confined interfacial film was measured. Strong monotonic increase of the shear relaxation time, elastic modulus, and effective viscosity were observed at spacings less than about 10 mole...

In this work, the local pressure of fluids confined inside nanoslit pores is predicted within the framework of the density functional theory. The Euler-Lagrange equation in the density functional theory of statistical mechanics is used to obtain the force balance equation which leads to a general equation to predict the local normal component of the pressure tensor. Our approach yields a genera...

studying csf (cerebro spinal fluid) is a simple and fast measure for diagnosing meningitis in children. for this reason, lp [umbar puncture] is used to treat csf.  regarding the side effects of lp, we decided to determine the positive points observed in the patients’ files than total patients confined to bed in our selected population. in this study conducted by descriptive retrospective method...

This paper is a commentary on the experimental observation observations of Bensimon et al. [1] of convection of a binary fluid mixture in a fluid annulus. They observed a convective pattern that is time periodic, but with non-zero amplitude confined to a stationary sector of the annulus. The symmetry properties of this state are paradoxical. There is no subgroup of the spatio-temporal symmetry ...

we report engineering experiences from the critical task of relief well installation under high artesian flow conditions at the downstream toe of the karkheh earth dam, iran. due to the establishment of excessive uplift pressure at the downstream toe of the karkheh dam, installation of a series of new relief wells was considered to permanently relieve part of these pressures. the mentioned upli...

During the past few decades molecular dynamics has been a widely applied tool to simulate fluid confined in micro/nano geometries. What makes interfacial fluids fundamentally different from the bulk fluid is the fact that their density varies considerably over microscopic distances. A class of such strongly inhomogeneous fluids are fluids confined in very narrow channels by solid boundaries. In...

Slow growth of calcite in confinement is abundant in Nature and man made materials. There is ample evidence that such confined growth may create forces that fracture solids. The thermodynamic limits are well known but since confined crystal growth is transport limited and difficult to control in experiment we have almost no information on the mechanisms or limits of these processes. We present ...
