The recent proliferation of stratigraphic studies of delta 13C variation in carbonates and organic C in later Neoproterozoic and basal Cambrian successions (approximately 850-530 Ma) indicates a strong oscillating trend in the C-isotopic composition of surface seawater. Alone, this trend does not adequately characterize discrete intervals in Neoproterozoic time. However, integrated with the vec...

Vertebrate paleontologists have proposed a model for the terrestrial end-Permian event in the Karoo Basin, South Africa. The scenario envisions vegetational collapse that resulted in a phased extinction of vertebrate taxa in the uppermost Daptocephalus Assemblage Zone and overlying Lystrosaurus Assemblage Zone. These biodiversity patterns are placed into composite stratigraphic sections at key ...

The universal mercury vapor black light trap is an effective device used for collecting moth specimens in a wide variety of habitats; yet, they can present challenges for researchers. The mercury vapor trap is often powered by a heavy automotive battery making it difficult to conduct extensive surveys in remote regions. The mercury vapor trap also carries a considerable financial cost per trap ...

Broomrapes are obligate root parasitic weeds and major constraint to many dicotyledoncrops especially in Mediterranean agricultural lands. Due to the fact that no single controlmeasure is able to control broomrapes in the field satisfactorily, integrated management isrecommended in general. The use of of trap crops or catch crops is an important strategy forcontrolling the weeds; and allelopath...

Purpose To identify the role of the fragment crystallizable (Fc) region in determining intraocular protein drug pharmacokinetics. Methods We generated a new VEGF-Trap lacking the Fc region (FcfVEGF-Trap, MWt = 100 kDa) by replacing the Fc region of native VEGF-Trap (MWt = 145 kDa) with a dimerized coiled-coil domain. Forty-two rabbits were injected intravitreally with VEGF-Trap or FcfVEGF-Tra...

The Quaternary Period is characterized by dramatic global climatic changes. fossil deposits, which can offer excellent stratigraphic resolution, provide a unique opportunity to understand how fauna respond past environmental change. Here, we test if the herpetofauna of McEachern’s Deathtrap Cave, late Pleistocene Holocene pitfall trap deposit from Victoria, Australia, shows climate-related shif...

The current study aims to utilize the Direct Hydrocarbon Indicators technique identify presence of hydrocarbons in Carbonaceous Mishrif Formation (Late Cretaceous) from 3D seismic data (post-stack) integrated with available information two wells (Du-1 and Du-2). 3D-seismic survey was carried out 2010, covering 602.62 km2, at Dujaila oil field Maysan, SE Iraq. Distinct features for hydrocarbon i...
