Coldwater-associated ulcers, i.e. winter ulcers, in seawater-reared Atlantic salmon Salmo salar L. have been reported in Norway since the late 1980s, and Moritella viscosa has been established as an important factor in the pathogenesis of this condition. As routine histopathological examination of winter ulcer cases in our laboratory revealed frequent presence in ulcers of long, slender rods cl...

We investigate geometric percolation and scaling relations in suspensions of nanorods, covering the entire range of aspect ratios from spheres to extremely slender needles. A new version of connectedness percolation theory is introduced and tested against specialised Monte Carlo simulations. The theory accurately predicts percolation thresholds for aspect ratios of rod length to width as low as...

Cases of Sparganum mansoni, caused by the plerocercoid larva of the tapeworm S. mansoni, occur throughout the world, particularly in Asian, Middle Eastern, and European countries. However, cases of infection with this parasite are rarely seen in Japan. Here, we present a case of a 61-year-old woman with a solitary subcutaneous nodule in left inner aspect of the thigh, from which a long, slender...

The luminal surface of the initial segment of the epididymal duct in the Japanese monkey was observed under a field emission type scanning electron microscope. The long, slender stereocilia projecting from the apical surface of the columnar cells were found to be closely arranged in a funnel-like form opening to the lumen. The funnels formed by stereocilia were also confirmed by observation of ...

—Netechma similis, new species, from Costa Rica, is described and illustrated, and Netechma caesiata (Clarke), new combination, from Venezuela, is redescribed and illustrated. Netechma Razowski belongs to a group of genera in Euliini characterized by one or more sparganothine-like features of the male genitalia, including a spiny transtilla; a long, slender, hooklike uncus; and densely scaled s...

Cosserat rods are models for long slender objects. Let SE(3) = R3 SO(3) be the 13 group of orientation-preserving rigid body motions of R3 (the special Euclidean 14 group). A configuration of a Cosserat rod is a map φ : [0,1] → SE(3). For each 15 s ∈ [0,1], the value φ(s) = (φr(s),φq(s)) is interpreted as the position φr(s)∈R and 16 orientation φq(s)∈ SO(3) of a rigid rod cross section. Strain ...

The Yellow Wagtail, Motacilla flava Linnaeus, Motacillidae (Passeriformes : Aves) is a slender 15 16 cm long bird that inhabits open country near water such as wet meadows. Cytological investigation depicted the diploid chromosome count between 78 and 85 with 80 as modal value. No structural uncertainty was observed between macroand microchromosomes. Z W were fourth in order of size, both sub-m...
