Background: Both sexes of bat flies in the families Nycteribiidae and Streblidae (Diptera: Hippoboscoidea) reside in the hair or on the wing membranes of bats and feed on blood. Members of the Nycteribiidae transmit bat malaria globally however extant streblids have never been implemented as vectors of bat malaria. The...

Background: It is rare to find terrestrial nematode lineages parasitizing arthropods inhabiting the intertidal or littoral zone of the oceans. During an ecological study along the Oregon dunes, an allantonematid nematode
(Tylenchomorpha: Allantonematidae) was discovered parasitizing the intertidal shore bug, Saldula laticollis (Reuter)
(Hemiptera: Saldidae). This shore bug is adapted...

A well preserved specimen of amber Strepsiptera was erroneously described as Stylops neotropicallis Kogan and Poinar, 2010. The taxonomic position of the species was based on a count of 6 antennomeres (typical of the Stylopidae), however, further observations showed that there are actually 7 antennomeres, which places the fossil in...

The purpose of this study was to identify any ostelogical features which might prevent
paradoxical movement (=lateral collapse) of the abdominal air sacs in birds during inhalation.
A combination of 26 fresh and frozen adult bird carcasses representing 10 avian orders were
procured from local sources. Dissections of each specimen...
Since its introduction in France 10 years ago, the yellow-legged Asian bee-hawking hornet Vespa velutina has rapidly spread to neighboring countries (Spain, Portugal, Belgium, Italy, and Germany), becoming a new threat to beekeeping activities. While introduced species often leave behind natural enemies from their original home, which benefits them in...
This study Is a rhetorical analysis of ten documents of Joseph
Smith, Jr's. early revelations spanning the period of 1829 to 1831
to determine the extent to which he used demagogic rhetoric in pursuit
of his goals. A definition of demagoguery is provided and is
applied in an analysis of...
Thin films are an enabling technology for a wide range of applications, from microprocessors to diffusion barriers. Nanolaminate thin films combine two (or more) materials in a layered structure to achieve performance that neither film could provide on its own. Atomic layer deposition (ALD) is a chemical vapor deposition technique...
The Columbia River plume region was investigated during the
period of 20 June to 3 July, 1968 by light scattering measurements
and standard hydrographic station observations. The Columbia
River plume was traced by the light scattering particles of the plume
water. The light scattering particles are estimated to be contained...
Present GEK (Geomagnetic Electrokinetograph) theory is extended
to include internal waves of the lowest mode. The predicted
towed electrode GEK signal is determined to second-order for long-crested
internal waves in a finite but deep ocean. The analysis includes
the determination of GEK signatures for small amplitude and
finite amplitude interfacial...
This study deals primarily with the evaluation and improvement of the content of a college-level drafting course for air conditioning engineering students. The necessity for better integration of the mechanical and architectural elements contained in the course, and an adequate coverage of field drafting room practices were the chief evidences...
