A sharp, well-defined interface between a late Pleistocene carbonate sandstone ridge (kurkar) and Holocene unconsolidated coastal siliciclastic sediment has formed largely as a consequence of recent structural activity along the NW Nile delta coast at Abu Qir, Egypt. Joint patterns in the coastal kurkar exposed on land, and its irregular and dislocated configuration beneath Abu Qir Bay, suggest...

In molting animals, a cuticular extracellular matrix forms the first barrier to infection and other environmental insults. In the nematode Caenorhabditis elegans there are two types of cuticle: a well-studied collagenous cuticle lines the body, and a poorly-understood chitinous cuticle lines the pharynx. In the posterior end of the pharynx is the grinder, a tooth-like cuticular specialization t...

Plesiadapids are extinct relatives of extant euarchontans (primates, dermopterans, and scandentians), which lived in North America and Europe during the Paleocene and Early Eocene. The only genus of plesiadapid whose species are absent from Paleocene strata is Platychoerops. Further, Platychoerops is the only group found in sediments post-dating the Paleocene-Eocene boundary (PEB) by a substant...

It has been recently suggested by Arkani-Hamed, Dimopoulos and Dvali that gravity may become strong at energies not far above the electroweak scale and thus remove the hierarchy problem. Such a scenario can be tested at both present and future accelerators since towers of Kaluza-Klein gravitons and associated scalar fields now play an important phenomenological role. In this paper we examine se...

a total of 76 specimens of three fish species including: hemiculter lucisculus (41), liza auratus (16) and gasterosteus aculeutus (19) were caught using handnet from 3 station in zardi river in the south-eastern costal of caspian sea at autumn and winter 2009 and spring 2010. the fishes were transported alive to the laboratory of shahid rajaee site. they were killed by cutting their spinal cord...
