A monoclinic modification of propane-1,3-diyl bis(pyridine-3-carboxylate)
No full textIn the title compound, C15H14N2O4, (I), the molecule lies on a twofold rotation axis which passes through the central C atom of the aliphatic chain, giving one half-molecule per asymmetric unit. The structure is a monoclinic polymorph of the triclinic structure previously reported [Brito, Vallejos, Bolte & López-Rodríguez (2010). Acta Cryst. E66, o792], (II). The most obvious difference between them is the O/C/C/C—O/C/C/C torsion angle [58.2 (7)° in (I) and 173.4 (3)/70.2 (3)° in (II) for GG and TG conformations, respectively]. Another important difference is observed in the dihedral angle between the planes of the aromatic rings [86.49 (7)° for (I) and 76.4 (3)° for (II)]. The crystal structure features a weak pi–pi interaction [centroid–centroid distance = 4.1397 (10)Å]; this latter kind of interaction is not evident in the triclinic polymorph

Generic and speci W c identi W cation. These specimens from the Cape Verdes correspond in diagnostic features to the original description of this species by Van Tassell et al. (1988), based on material from the Canaries and Guinea. Their meristic features are D1 VI, D2 I /10 (10±11), A I /9, P 18 (17±18), and LL 24±27. Biology. At the Cape Verdes localities, the species was collected in 11±16 m on mixed substrata of sand, stones, calcareous algae, and rock, within a depth range of 9±45 m noted elsewhere (Van Tassell et al., 1988). The ®nding of V. canariensis at the Cape Verdes supports the suggestion by Van Tassell et al. (1988) that this is a tropical species whose northern limit of distribution now appears to be at Madeira (Debelius, 1998).Published as part of Brito, A. & Miller, P.

A ±25A Versatile Shunt-Based Current Sensor with 10kHz Bandwidth and ±0.25% Gain Error from -40°C to 85°C Using 2-Current Calibration
No full textAccurate current sensing is critical in many industrial applications, such as battery management and motor control. Precise shunt-based current sensors have been reported with gain errors of less than 1% over the industrial temperature range (-40°C to 85°C) [1]–[4]. However, since they are intended for coulomb counting, their bandwidth is limited to a few tens of Hz, making them unsuitable for battery impedance or motor-current sensing. This paper presents a current sensor with a wide (10kHz) bandwidth and a tunable temperature compensation scheme (TCS), which allows it to be flexibly used with different types of shunts while maintaining high accuracy. A low-cost room-temperature calibration scheme is proposed to optimize gain flatness over temperature by exploiting the shunt's self-heating at large currents. Over the industrial temperature range and a ±25A current range, it achieves state-of-the-art gain error (±0.25%) with both low-cost PCB and stable metal-alloy shunts.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Electronic InstrumentationMicroelectronic

[Review of] Silvester J. Brito. The Way of a Peyote Roadman
No full textThe Way of a Peyote Roadman is a work which is certain to stir controversy in a number of academic circles. Silvester J. Brito holds a Ph.D. in folklore and anthropology from Indiana University. The book begins with a personal affirmation of the author\u27s belief in the power of sorcery, based on his personal experiences culminating in a peyote ritual curing ceremony
