Pentamyrmex spinosus new genus, new species is described, and a new tribe is erected for this remarkable insect. This is the first report of ant mimicry in the Pentatomidae.

Blue plaques on London houses associated with famous people are a familiar sight to the Londoner as well as to the visitor to the metropolis. There are at present around 400 of these plaques, which commemorate the eminent in many walks of life, such as politics, the law, the arts, and the sciences. Of these, a couple of dozen relate to medicine, and it is these that I have collected together he...

An elementary geometric construction, known as Napoleon’s theorem, produces an equilateral triangle, obtained from equilateral triangles erected on the sides of any initial triangle: The centers of the three equilateral triangles erected on the sides of the arbitrarily given original triangle, all outward or all inward, are the vertices of the new equilateral triangle. In this note, we observe ...

The audible noise (AN) of HVDC transmission lines, as an external manifestation the corona discharge, intensifies with increase altitude. In high-altitude area, AN has been a key factor in determining type conductors for lines. order to study characteristics current and lines at high-altitude, we erected test line altitude 4300 m, carried out tests under different voltages. Through test, basic ...

Seven Western Hemisphere genera (six known and one new), and 39 species (27 known and 12 new) of Lasiochilinae are redefined based on known and new characters. These new characters are briefly discussed. Plochiocorini, a new tribe, is erected in the basis of two genera: Plochiocoris Champion and Dolichiella Reuter. Anaelia, a new genus of Lasiochilini, is also erected based on the species Lasio...

Gypseous soil, as is well known, includes a specific quantity of gypsum. Gypsum water-soluble salt with solubility (2.2-2.6) gram/liter in distilled - water. As result, the presence gypsum poses challenge when building structures on this since dissolves exposed to water, producing gaps between soil particles and so causing collapse. This study examines behavior shallow foundation rested gypseou...

Abstract With the rapid development of China's economy, electricity demand is increasing and scale power grid construction expanding. Large-scale transmission substation projects leads to an shortage corridors, which inevitably formation parallel erection AC DC patterns. When lines are erected in parallel, coupling effect makes hybrid electromagnetic environment more complicated. In this paper,...
