Synthesis, Characterization, Critical Micelle Concentration and Antimicrobial Activity of Two-headed Amphiphiles
… is about the synthesis of homologous series of two-headed, long-chain amphiphiles (the 2CCbn series, where n = 16, 18, 20, 22, 30, 5α-cholestan-3Ã -ol). The 2CCbn series was synthesized in five steps. The first step involves a reaction of nitroethane and two equivalents of tert-butyl acrylate to …

Synthesis, Characterization, Critical Micelle Concentration and Biological Activity of two-Headed Amphiphiles
… a new homologous series of five long-chain, two-headed amphiphiles [2CAm13, 2CAm15, 2CAm17, 2CAm19, 2CAm21; CH3(CH2)n-1CONHC(CH3)(CH2CH2COOH)2, n = 13, 15, 17, 19, 21]. The synthesis of the 2CAmn series was accomplished in four steps. The first step involves a reaction of nitroethane and two …

Symbolic masters/semiotic slaves : subjectivity and subjection in Atwood, with reference to The circle game and Two-headed poems
… of the subject via a relationship of power in two poem sequences, 'The circle game' and 'Two-headed poems', by Margaret Atwood. I argue that Atwood proposes a subject similar to the kind of subject found in psychoanalysis. Like the psychoanalytic subject, Atwood's subject is formed in relation …

Fixed and Adaptive Multiple-Pinhole Apertures for Brain SPECT Imaging
… was developed to mount to an existing clinical two-headed SPECT system, the Philips Brightview, such that one camera collects images with conventional collimation while the second uses our custom design. The adaptive multi-pinhole aperture was developed for a novel stationary brain imager called …

Re-Alimentaciones-Cruzadas: Procesos de Re-imaginación entre Epistemologías Acústicas/Cross-Feedback: Re-Imagining processes between Acoustemologies
… to transcend juxtapositions. Re-imagining two mythological snakes, the Amphisbaena, and the Ouroboros, the reader is invited to revalue their placement in intricate post-colonial realities by imagining metaphysical circuits connecting different spaces and times. The work presents a series …

Myosin structural dynamics: mechanistic insights and therapeutic technology developments
… mavacamten stabilizes an auto-inhibited state of two-headed cardiac myosin, not present in the single-headed myosin motor fragment. From these results, we predicted that cardiac myosin is regulated by an interaction between its two heads and the thick filament, and proposed that mavacamten …
