The rostrum is a large diameter, thin-walled tubular structure that receives loads from the teeth. The rostrum can be conceptualized both as a rigid structure and as an assemblage of several bones that interface at sutures. Using miniature pigs, we measured in vivo strains in rostral bones and sutures to gain a better understanding of how the rostrum behaves biomechanically. Strains in the prem...

Four new species of the genera Dryophthoroides Roelofs, 1879 and Nephius Pascoe, 1885 from tribe Stromboscerini subfamily Dryophthorinae are described illustrated. telnovi Legalov, sp. nov. New Guinea (Star Mountains) is similar to D. seftoni (Zimmermann, 1944) bit differs in shorter thicker rostrum narrower pronotum. It distinguish beccarii (Pascoe, 1885) smaller body size, rostrum, coarser pu...

Purposes: The corpus callosum (CC) is the largest bundle of white matter fibers interconnecting the 2 hemispheres. The development starts at 14 weeks of gestation and there is a posterior (splenium) to anterior (genu) gradient of myelination, although the genu grows prior to the splenium. Abnormal CC development has been observed in preterm infants [1], low birth weight children [2], and neonat...

We compared the mechanical properties of 'ordinary' bovine bone, the highly mineralized bone of the rostrum of the whale Mesoplodon densirostris, and mother of pearl (nacre) of the pearl oyster Pinctada margaritifera. The rostrum and the nacre are similar in having very little organic material. However, the rostral bone is much weaker and more brittle than nacre, which in these properties is cl...

A new species of Numbakulla Guţu & Heard, 2002 (Tanaidacea) is described from Heron Island (southern Great Barrier Reef, Queensland) collected during the Census of Coral Reefs Ecosystem (CReefs) program. The new species is the third member of the family and can be recognized by the combination of characters as: length/width ratio of the body, which is 6:7, pereonite 4 longer than the rest, the ...

This paper introduces a new program to find high-redshift radio galaxies in the southern hemisphere through ultra-steep spectrum (USS) selection. We define a sample of 234 USS radio sources with spectral indices α 408 ≤ −1.0 (Sν ∝ ν α) and flux densities S408 ≥ 200 mJy in a region of 0.35 sr, chosen by cross-correlating the revised 408 MHz Molonglo Reference Catalogue, the 843 MHz Sydney Univer...

The new cymothoid species, Elthusa winstonisp. n., a branchial parasite of fishes from the family Acanthuridae Bonaparte, 1835 in Hawaii, is described and figured. The female adults can be distinguished by the strongly vaulted body and compacted body shape; rostrum with a small median point; short antennae which are close together (only 6 articles in both antennula and antenna); short and wide ...

Cambarus (Puncticambarus) callainus, new species, is a stream-dwelling crayfish endemic to the Big Sandy River basin in Kentucky, Virginia, and West Virginia. Within the basin, C. callainus occurs in the Levisa, Tug, and Russell fork watersheds. The new species is morphologically and genetically most similar to Cambarus veteranus, which is endemic to the Upper Guyandotte River basin of West Vir...

Nautilocaris saintlaurentae gen. nov., sp. nov., is described and illustrated from hydrothermal vents in the North Fiji Basin and Lau Basin in the south-western Paci¢c. This new taxon is assigned to the Alvinocarididae. It has a well-developed, dorsally dentate rostrum, carapace with pterygostomian spine present, eye broadly fused mesially, epipod^setobranch complex present above pereopods, and...
