A d-angulation is a planar map with faces of degree d. We present for each integer d ≥ 3 a bijection between the class of d-angulations of girth d and a class of decorated plane trees. Each of the bijections is obtained by specializing a “master bijection” which extends an earlier construction of the first author. Bijections already existed for triangulations (d = 3) and for quadrangulations (d...

Gentlemen,?I take the liberty of submitting to you several drawings which illustrate the condition of the entrance to the vagina, and especially of the hymen, after cohabitation and childbearing. It is known to you, that hitherto the general opinion has been that the hymen by the first cohabitation was torn, and that the cicatricial retracting remains of the same formed the carunculee myrtiform...

In this paper, an attempt has been made to investigate the reflectance of various colours and effects of vary-ing colours on human working and production. Different colours have different reflectance and energy associ-ated with it. Colours play a significant role in the colour scheme of the houses, offices, factories etc. The col-ours may be seen on walls, tabletops, equipment, machines etc. In...
