A two-step chromatographic procedure was developed for the isolation and purification of hen IgY antibodies from egg yolk. The antibodies were completely separated from vitellin and lipids by hydrophobic interaction chromatography followed by gel filtration. Almost no residual yolk proteins, no immunoglobulin aggregates, and no antibody fragments could be detected in the final extract. Moreover...

due to the tilt of the platform carrying the synthetic aperture radar(sar), the image formation algorithms(like rda) can not yield to good quality images from the ground. therefore, it is convenient to use a two-step approach for motion compensation in image formation algorithms. in this paper, using an approximated linear model for the motion error and the impact of range compression step of r...

Two known results in multiple testing, one relating to the directional error control of augmented step-down procedure proved by Shaffer (1980) and the other on the monotonicity of the critical values of step-up procedure proved by Dalal and Mallows (1992), are revisited and improved in this article. Shaffer’s result on the directional error control property of augmented step-down procedure with...

This paper presents a methodology for the assessment of ductility and strength capacities in low-rise buildings. This method utilizes the characteristics of force-displacement for the lowest story level or considers the weakest story in any given low-rise building for its primary analysis. Calculations are based on two levels of earthquake motions, namely strong earthquakes (PGA=0.3 g), and ver...

In this paper, we show a general way to interpret the infrastructure of a global field of arbitrary unit rank. This interpretation generalizes the prior concepts of the giant-step operation and f -representations, and makes it possible to relate the infrastructure to the (Arakelov) divisor class group of the global field. In the case of global function fields, we present results that establish ...

We discuss the nonabelian world-volume action which governs the dynamics of N coincident Dp-branes. In this theory, the branes’ transverse displacements are described by matrix-valued scalar fields, and so this is a natural physical framework for the appearance of noncommutative geometry. One example is the dielectric effect by which Dp-branes may be polarized into a noncommutative geometry by ...
