Androgyny/Hermaphroditism: Hebrew Bible

The Hebrew Bible lacks a term for androgyny or hermaphroditism. The term tumtumim, which identifies persons of indeterminate or “hidden” sex, appears later in rabbinic texts. Nevertheless, sexual fluidity, ambiguity, intersexed persons, and persons with a combination of masculine and feminine characteristics appear in the Genesis creation stories and prophetic texts. While gender transgression is relevant to the general discussion, this entry from The Oxford Encyclopedia of the Bible and Gender Studies: Oxford Biblical Studies Online focuses primarily on ancient understandings, namely those presented in the Hebrew Bible, of those of “both sexes.

Orbital tube flaring system produces tubing connectors with zero leakage

An orbital tube flaring system produces tubing connectors with a zero-leak potential needed in high pressure hydraulic and pneumatic systems. The flaring system incorporates a rolling cone and rolling die to closely control flare characteristics

Bird Migration Through A Mountain Pass Studied With High Resolution Radar, Ceilometers, And Census

Autumnal migration was studied with high-resolution radar, ceilometer, and daily census in the area of Franconia Notch, a major pass in the northern Appalachian Mountains. Under synoptic conditions favorable for migration, broadfront movements of migrants toward the south passed over the mountains, often above a temperature inversion. Birds at lower elevations appeared to be influenced by local topography. Birds moving southwest were concentrated along the face of the mountain range. Birds appeared to deviate their flights to follow local topography through the pass. Specific migratory behavior was not associated with species or species groups. Under synoptic conditions unfavorable for southward migration, multimodal movements probably associated with local flights were as dense as the southward migrations described above. Avian migrants reacting to local terrain may result in concentrations of migrants over ridge summits or other topographic features

The Tits alternative for generalized triangle groups of type (3, 4, 2)

A generalized triangle group is a group that can be presented in the form G = h x, y | xp = yq = w(x, y)r = 1 i where p, q, r ? 2 and w(x, y) is a cyclically reduced word of length at least 2 in the free product Zp ? Zq = h x, y | xp = yq = 1i. Rosenberger has conjectured that every generalized triangle group G satisfies the Tits alternative. It is known that the conjecture holds except possibly when the triple (p, q, r) is one of (2, 3, 2), (2, 4, 2), (2, 5, 2), (3, 3, 2), (3, 4, 2), or (3, 5, 2). Building on a result of Benyash-Krivets and Barkovich from this journal, we show that the Tits alternative holds in the case (p, q, r) = (3, 4, 2)
