We report on the design and performance of in-house built column cartridges that can be directly screwed into ports a commercial rotor-stator valve to minimize extra-column band broadening pressure-drop losses when pursuing ultra-fast separations such as those needed in 2D 3D-LC separations. Two basic designs were evaluated compared with results obtained screw-in cartridge. The system produces ...
Wetting phenomena are studied for a fibre bundle consisting of three parallel cylinders of radius b. Two types of long liquid column (a disintegrated and a channel-filling column) and a state akin to the unduloid can form, depending on whether the cylinder-cylinder separation, 2d, is larger or smaller than certain critical values. The dimensionless threshold values d/b have been calculated, whe...

The migration of dislocations affects many material properties including deformation, plasticity and electronic properties. In order to understand the mechanism of the motion of dislocations, both experimental and theoretical studies have been performed [1]. It is known that full dislocations such as edge or screw dislocations can dissociate into Shockley partial dislocations, which have higher...
Let A and B be n × m matrices. The matrix B is said to be g-row majorized (respectively g-column majorized) by A, if every row (respectively column) of B, is g-majorized by the corresponding row (respectively column) of A. In this paper all kinds of g-majorization are studied on Mn,m, and the possible structure of their linear preservers will be found. Also all linear operators T : Mn,m ---> Mn...
the accurate prediction of protein stability is one of the most challenging goals in protein formulation and delivery. in this study, a gradient rp-hplc method is described for the separation of human growth hormone (hgh) variants as deamidated and oxidized forms. the methodology employed a polymeric poly (styrene-co-divinylbenzene) column and a 1ml/min flow rate of a linear gradient of 0.1% v/...
