Context. Magnetic fields are proposed to play an important role in the formation and support of self-gravitating clouds and the formation and evolution of protostars in such clouds. Aims. We attempt to understand more precisely how the Pipe nebula is affected by the magnetic field. Methods. We use R-band linear polarimetry collected for about 12 000 stars in 46 fields with lines of sight toward...

A sample of 14 pre-main sequence visual binary systems in southern star-forming regions were imaged at 2 μm with the Keck I telescope to search for tertiary companions, scatteredlight disks, and compact nebulae at linear scales of 5–100 AU. Speckle holography was used to produce images with diffraction-limited resolution and high dynamic range, and photometry in four filters between J (1.25 μm)...

This article is a response to Huber (2013) Notes on the occasion of reading Jesús Huerta de Soto. We first analyze and critique five main arguments brings forward against Soto’s theory monetary reform plan. Second, we clarify some Huber’s misunderstandings regarding Austrian economics in general. Finally, proceed criticize New Currency School ideal system 100% fiat money.

THE CRYSTAL STRUCTURE OF THE TITLE COMPOUND [SYSTEMATIC NAME: 3,5,7-triaza-1-azoniatricyclo-[3.3.1.1(3,7)]decane (E)-3-carb-oxy-prop-2-enoate], C(6)H(13)N(4) (+)·C(4)H(3)O(4) (-), had been determined previously by Bowes et al. [Acta Cryst. (2003), B59, 100-117]. Their structure contained an approximately 3:1 ratio of fumarate and succinate monoanions disordered over the same position. The succi...

While the Earth system is in overshoot mode with an imminent threat to our social, ecological, and economic systems, cultural evolutionary theory may hold key more successfully addressing many of sustainability challenges. With aim illuminating potential studying evolution a sustainable bioeconomy through lens, this article outlines contours novel research avenue form five propositions. It cont...

Bio-probes that inhibit the action of auxin are useful tools for the study of auxin signaling. To screen for specific inhibitors of auxin signaling, we used an Arabidopsis transgenic line harboring the auxin-inducible promoter derived from PS-IAA4/5 and the reporter gene, GUS (beta-glucuronidase). In this transgenic plant, the exogenous auxin specifically enhanced the expression of the GUS repo...
