It has been proved by Loader [2] that Statman-Plotkin conjecture (see [5] and [4]) fails. The Loader proof was done by encoding the word problem in the full type hierarchy based on the domain with 7 elements. Later Loader refined the result by establishing that the problem is undecidable for every finite domain with 3 ground elements [3]. The remaining non trivial case with 2 ground elements ha...

The significance of the recent finding of the velocity distribution function of the steady-state Boltzmann equation under a steady heat current obtained by Kim and Haykawa (J. Phys. Soc. Jpn. 72, 1904 (2003)) is discussed. Through the stability analysis, it seems that the steady solution is stable. One of possible applications to the nonequiliburium Knudsen effect in which one cell at equilibri...

sion. He was treated, however, with quinine and emetine. The fever subsided the next day, but the supposed hepatic enlargement remained. After six injections of emetine, gr. 1 each, the enlargement on the right side remained, and the patient was examined by Dr. Moncrieff Joly, my Principal Medical Officer. He discovered that a distinct splenic notch could be felt in the mass on the right side; ...

Five species of amphibians, Leptodactylus podicipinus, Scinax acuminatus, S. nasicus, Rhinella fernandezae and Pseudis paradoxa, were collected in Corrientes province, Argentina and searched for larval nematodes. All larval nematodes were found as cysts in the serous of the stomach of hosts. Were identified one superfamily, Seuratoidea; one genus, Spiroxys (Superfamily Gnathostomatoidea) and on...

Experimental infections of three hematophagous arthropods (Rhodnius prolixus, Aedes aegypti, and Culex pipiens) with a trypanosome of the Trypanosoma rotatorium complex found in the frogs Hyla crepitans and Leptodactylus insularum revealed that A. aegypti is a good host for the flagellate; the course of development in the intestinal tract of the mosquito is described from 15 minutes to 168 hour...

Organs of crayfishes--mainly integument of Astacus leptodactylus--have been kept in an in vitro culture of several days. The medium consists of 2 parts of van Harreveld saline and one part of horse serum, supplemented with antibiotics for long term cultures. This medium is very similar to the Astacus hemolymph in its ionic content, the pH, the osmolarity, the protein concentration and the chole...
