Abdomen with shorter setae throughout, denser tuberculation on tergite XII.
The formation of small corrosion bumps on the inside walls of pipes - known as tuberculation - interferes with water flow and causes discolouration and pressure problems for consumers.
plautini), such as wider and more trapezoidal LA, more elongate L1, wider anterior fixigena and heavier (denser and larger-sized) tuberculation, and possibly also in attaining bigger maximum size, although it is cautioned that the available material comprises only very few specimens.
Skin of dorsum in males finely tuberculate (not spinulate), that of females appears smooth but under magnification bears a tuberculation similar to but less dense than in males.
Using torpedo-shaped tools specially designed for this purpose, the Spiniello team cleaned out the excess tuberculation built up over the years on the unlined cast iron water mains.
Within the milesi group the new species differs from the other five forms which also have toe fringes in size of the finger disks, the snout shape in profile and the amount of toe webbing and dorsal tuberculation. Difficulties in distinguishing among the character states for the tympanum (distinct, indistinct and hidden) and between toe ridges and fringes indicate that very subtle differences separate recognized species.
While the concrete lining installed by the taxpayer in Plainfield-Union did not provide a "permanent" resolution of the tuberculation problem caused by acidic river water, the expenditures provided a long-term solution.(6) Moreover, a fair reading of the Plainfield-Union decision shows that "permanency" did not play an important role in Tax Court's analysis.(7) In particular, the court cited several cases in which repairs were held to be deductible even though the expenditures constituted a permanent solution to the particular problem.(8) More important, the removal and replacement of asbestos in the TAM were no less permanent than the soil removal and replacement activities in Rev.
An analysis of the ten Recent Echinocardium species was undertaken on a set of about 30 characters dealing mostly [TABULAR DATA FOR TABLE 1 OMITTED] with the architectural array of the plates and with the general morphology and tuberculation of the test.
The process helps to restore internal pipe diameters, increasing flow, improving efficiency, minimizing water loss and helping to prevent additional corrosion and tuberculation.
9L, M) differs from the one described above in having a larger pleural field, a larger articulating half-ring, a longer axis that is sub-conical, deeper axial furrows and more irregular tuberculation. However, there is certain similarity between this pygidium and the one attributed to Dinesus spinellosus in the lack of segmental axial rings, in the small convex pleura and in the ornament of tubercles of varying size.
Puparia of Tuberaleyrodes species have dorsal setae on elongated tubercles, and the pattern of tuberculation is useful for species identification (Dubey et al.
