Criteria for successful separation by continuous electrophoresis and electrochromatography in blocks and columns

By analysis of some important process variables, criteria for successful separation by continuous electrophoresis and electrochromatography in packed beds are derived. A general theory correlating power input, residence time and temperature rise in cylindrical and rectangular geometries is presented. The limitation of the separating capacity by transverse diffusion effects is shown to be predictable in terms of other operational conditions. These separation criteria appear to be in agreement with experimental evidence, and may find analytical as well as preparative application

Sequence-selective detection of double-stranded DNA sequences using pyrrole-imidazole polyamide microarrays

We describe a microarray format that can detect double-stranded DNA sequences with a high degree of sequence selectivity. Cyclooctyne-derivatized pyrrole-imidazole polyamides were immobilized on azide-modified glass substrates using microcontact printing and a strain-promoted azide-alkyne cycloaddition (SPAAC) reaction. These polyamide-immobilized substrates selectively detected a seven-base-pair binding site incorporated within a double-stranded oligodeoxyribonucleotide sequence even in the presence of an excess of a sequence with a single-base-pair mismatc

Immigration policy and belonging: ramifications for DACA recipients’ sense of belonging

The socioeconomic benefits of the Deferred Action for Childhood Arrivals program initiated in 2012 by executive order from then-president Obama have been documented in the recent literature. However, the consequences of the legal challenge brought against the program by the Trump administration have not yet been fully examined. This article analyzes qualitative data from Latino Deferred Action for Childhood Arrivals recipients in California to assess how the legal turmoil around the program is affecting their sense of belonging in the United States. We find that the uncertainty around the program has negative consequences on their sense of belonging, despite the program’s aims at improving it, and despite the respondents’ living in a rather welcoming state in terms of state-level immigration policies. Notably, we find that respondents feel increasingly alienated from and unwanted in American society and postpone major life goals
