abstract background: pregnancy can be in conflict with sexual function which can be affected by physical and psychological changes during pregnancy. therefore, comparison of the effect of face‑to‑face education with group education on sexual function during pregnancy in couples was the purpose of this research. materials and methods: in this quasi‑experimental pre‑test post‑test study, 64 pregn...

1] demonstrates that simple schematic faces evoke neural responses comparable to those evoked by photographic face stimuli. The authors argue that this shows that schematic visual stimuli may still validly represent face processing, although it has been argued that such non-photographic faces lack many of the visual properties of the human face. In this commentary I would like to elaborate on t...

cephalometry is an important branch of anthropology in which the dimensions of head and face can be determined. these dimensions are used to show indexes for studying brain growth and formation of all types of head and face. indexes are vary from 65 to 95 for head and 65 to105 for face, which are used to determine 4 international anatomic types of head and 5 international anatomic types of face...

In the title compound, C(19)H(19)FN(2)O(2)S, the hydrogenated six-membered ring of the carbazole unit adopts a half-chair conformation and the plane of the fluoro-phenyl ring forms a dihedral angle of 41.5 (1)° with respect to the carbazole mean plane. The crystal structure is segregated into layers containing the carbazole units and fluoro-phenyl rings in alternate (200) planes. The carbazole ...

Microproblematica are microfossils whose suprageneric taxonomic status is unknown. Many microproblematica display an encrusting way of life and can therefore be included in the group of “micro-encrusters” that during the Upper Jurassic were conspicuous components of microbial carbonate crusts (e.g. LEINFELDER et al., 1993; SCHMID, 1996; DUPRAZ & STRASSER, 1999, 2002). These forms are widespread...

As a growing number of low-resolution (LR) face images are captured by surveillance cameras, LR face recognition has been a hot issue for recent years. Previous efforts on LR face recognition typically assume each subject has multiple high-resolution (HR) training samples. However, this assumption may not hold in some special cases such as law-enforcement where only a single HR sample per perso...

Almost all spiders building vertical orb webs face downwards when sitting on the hubs of their webs, and their webs exhibit an up-down size asymmetry, with the lower part of the capture area being larger than the upper. However, spiders of the genus Cyclosa, which all build vertical orb webs, exhibit inter- and intraspecific variation in orientation. In particular, Cyclosa ginnaga and C. argent...

Let G be a graph. It was proved that if G is a planar graph without {4, 6, 7}-cycles and without two 5-cycles sharing exactly one edge, then G 3-colorable. We observed that the proof of this result is not correct. 1 Let G be a simple graph with vertex set G. A planar graph is one that can be drawn on a plane in such a way that there are no “edge crossings,” i.e. edges intersect only at their co...
