The skin of a normal adult black-agouti (gray) mouse appears to be dull white in color. On the surface, however, small patches of black are to be seen at certain exposed sites, such as, in the male, on the tip of the penis and on the end of the scrotum, and, in the female, on the dorsal lip of the vagina. Other larger black areas may be made out in the skin after the hair has been removed. With...

Xylotrechus tristisfaciessp. n. (Coleoptera, Cerambycidae, Cerambycinae, Clytini) from China is described and illustrated. Characters distinguishing the new species from its close relatives, which possess an entirely black or dark brown pronotum with a black median stripe on the disc and dense yellowish to gray pubescent elytra with black or brown spots or bands, are presented.

When several gray midtones are present, like a black and white photo, two values are no longer sufficient to encode all the possible gray intensities, and to each pixel must be associated a numerical value, proportional to the brightness of that point. Typical choices for these values fall in the ranges 0 31 or 0 255 (requiring respectively 4 and 8 bits for each pixel). This second kind of imag...

during april 2013, branches of oak (quercus brantii lindl.) with fungal infection were collected from kohkiluyeh and buyer ahmad province of iran. laboratory survey indicated acervuli on the samples of oak dead twigs (3mm diameter). acervuli immersed in bark, were scattered, small (500µm), flat to subconical, 3-4 angled gray to black, hymenium labyrinthiform, pale grey, finally smeared over wit...

tinea capities is the commonest dermatophytosis in children with diverse clinical presentations. the causative fungi of tinea capitis vary with geographic area and time.this study was aimed to identify the etiologic agents and determine the related factors of tinea capitis in tehran, iran. from clinically suspected cases of tinea capitis, microscopy and culture were performed. of 58patients 96%...

As a way to further improve the electronic properties of group V layered semiconductors, we propose to form in-layer 2D heterostructures of black phosphorus and gray arsenic. We use ab initio density functional theory to optimize the geometry, determine the electronic structure, and identify the most stable allotropes as a function of composition. Because pure black phosphorus and pure gray ars...

However, curent three major technology groups such as ActiveX/DCOM, CORBA, and Java provide similar but different software architectures. This causes architecture nightmare. The component users need to consider the matching at the different levels of architecture as well as between the different technology groups as illustrated in Fig. 2. Furthermore, there are three different styles of compone...
