An improvement has been made to couple isoelectric focusing (IEF) sample injection and capillary zone electrophoresis in an untreated fused silica capillary. Electroosmotic flow is efficiently prevented by simply using a rubber block at the outlet end of the capillary during IEF sample injection. The experimental conditions that affect the concentration effect are discussed. A concentration enh...

For accurate micro-scale quantification of a specific protein in biological fluids, immunoaffinity chromatography (IAC) and isoelectric focusing (IEF) were combined in a single fused-silica capillary. The inner wall of the capillary was coated with an anti-E-tag antibody at the inlet side to form an IAC column, and polydimethylacrylamide, a neutral polymer, at the outlet side to form the capill...

We study the approximation problem of IEf(XT ) by IEf(Xn T ), where (Xt) is the solution of a stochastic differential equation, (Xn t ) is defined by the Euler discretization scheme with step Tn , and f is a given function. For smooth f ’s, Talay and Tubaro have shown that the error IEf(XT )−f(Xn T ) can be expanded in powers of 1 n , which permits to construct Romberg extrapolation procedures ...

Sphenia fragilis é um molusco bivalve pertencente a família Myidae, que possui hábito de escavar e viver alojado em espaços livres, cavidades e/ou fendas deixadas por outros organismos (e.g., mexilhões ostras). A espécie apresenta elevada variação morfológica na forma da concha, no entanto, ainda não foi estudado essa partir dados morfométricos. Objetivou-se testar hipótese existência uma estab...

Context. The inverse Evershed flow (IEF) is a mass motion towards sunspots at chromospheric heights. Aims. We combined high-resolution observations of NOAA 12418 from the Dunn Solar Telescope and vector magnetic field measurements Helioseismic Magnetic Imager (HMI) to determine driver IEF. Methods. derived line-of-sight (LOS) velocities spectra H α Ca II IR. HMI data were used in non-force-free...

Using G£rdenfors's notion of epistemic entrenchment, we develop the semantics of a logic which accounts for the following points. It explains why we may generally infer If -~A then B if all we know is AVB while must not generally infer If -~A then B if a~ we know is {AVB,A}. More generally, it explains the nonmonotonic nature of the consequence relation governing languages which contain conditi...
