Fibre-packed coalescers are widely employed to remove drops from liquid-liquid dispersions. This work has as its objective a quantitative correlation of drop removal with$ltration variables. Photo-etched screens, which were positioned perpendicular to the flow, served as geometrically defined representations sf jibrous media. Forward-angle light scattering was employed to measure the extent of ...

Re-epithelization and the formation of a granulation tissue consisting of in ̄ammatory cells, newly formed blood vessels, and ®broblasts embedded in a loose collagenous extracellular matrix, are critical events occurring during wound healing. In this study, utilizing the chick embryo chorioallantoic membrane (CAM) as an in vivo model of wound healing, we investigated the role of endogenous and e...

The contribution of terrigenous organic matter (TOM) to high molecular weight dissolved and particulate organic matter (POM) was examined along the salinity gradient of the Delaware Estuary. Dissolved organic matter (DOM) was fractionated by ultra®ltration into 1±30 kDa (HDOM) and 30 kDa±0.2 mm (VHDOM) nominal molecular weight fractions. Thermochemolysis with tetramethylammonium hydroxide (TMAH...

A 20-year-old Japanese woman visited our hospital complaining of butter£y-like in¢ltrative erythema on her cheeks. She also complained of arthralgia and persistent slight fever. Physical examination revealed oedematous erythema on her upper back and pea-sized whitish macules and brownish nodules scattered on her upper limbs (Fig. 1a). Some of the lesions had an atrophic surface. Laboratory ¢ndi...

Denote by R the power series ring in countably many variables over a eld K; then R 0 is the smallest sub-algebra of R that contains all homogeneous elements. It is a fact that a homogeneous, nitely generated ideal J in R 0 have an initial ideal gr(J), with respect to an arbitrary admissible order, that is locally nitely generated in the sense that dimK gr(J) d P d?1 j=1 R 0 j gr(J) d?j < 1 for ...

Ultrafi ne grained (UFG) and nanocrystalline (NC) metals, unlike coarse-grained metals, often show inelastic strain recovery during unloading, which is referred to as early Bauschinger effect. Several experimental and simulation studies have focused on the microscopic origins of this unusual mechanical behavior. However, the strain rate dependence of early Bauschinger effect in UFG and NC metal...

In this paper we show that the limiting distribution of the real and the imaginary part of the Fourier transform of a stationary random …eld is almost surely an independent vector with Gaussian marginal distributions, whose variance is, up to a constant, the …eld’s spectral density. The dependence structure of the random …eld is general and we do not impose any restrictions on the speed of conv...

Objective: Perfect surgical technique for gynecomastia treatment has not been established although several method have been described. Liposuction is very useful method however skin excess remains as a challenge for gynecomastic breast treatment. Materials and Methods: Prospectively; 9 selected patients (6 bilateral, 3 unilateral breasts) who were operated for gynecomastia with conventional lip...

Molecular mass distribution and ̄uorescence characteristics of organic ligands for copper(II) in freshwater were, for the ®rst time, investigated using ultra®ltration, immobilized metal ion anity chromatography (IMAC) and threedimensional excitation-emission matrix spectroscopy (3DEEM). Two types of humic-like ̄uorescence (Peaks A and B) were found in all molecular ligand fractions, while an a...

We study the following adaptive stochastic control problem: to maximize the probability PX(T) = 1] of reaching the \goal" x = 1 during the nite time-horizon 0; T], over \control" processes () which are adapted to the natural ltration of the \observation" process Y (t) = W(t) + Bt; 0 t T and satisfy almost surely R T 0 2 (t)dt < 1 and 0 X(t) = x + R t 0 (s)dY (s) 1; 80 t T. Here W() is standard ...
