A numerical investigation has been executed in a curve-shaped enclosure crammed with hybrid nanofluid containing wavy-shaped inner cylinder the existence of magnetic field. mixture copper and alumina nanoparticles normal water-based solution is used to create nanofluid. The natural convective flow generated as result temperature difference between cold outer hot wavy cylinder. parametric examin...

Fossils of a predatory dinosaur provide novel information about the evolution of unenlagiines, a poorly known group of dromaeosaurid theropods from Gondwana. The new dinosaur is the largest dromaeosaurid yet discovered in the Southern Hemisphere and depicts bizarre cranial and postcranial features. Its long and low snout bears numerous, small-sized conical teeth, a condition resembling spinosau...

In order to further improve the penetration power of multi-explosive formed warhead, tantalum is used design a folded warhead. Firstly, using numerical simulation, parameters damage element two different forming methods are obtained. Then formation process, flight and process projectile were calculated, respectively. Finally, static explosion experiment warhead was carried out. The results show...

The fossil record is the only source of information on the long-term dynamics of species assemblages. Here we assess the degree of ecological stability of the epifaunal pterioid bivalve assemblage (EPBA), which is part of the Middle Devonian Hamilton fauna of New York--the type example of the pattern of coordinated stasis, in which long intervals of faunal persistence are terminated by turnover...

Laparoscopic Adjustable Gastric Banding (LAGB) was done for the first time in Belgium in 1993. Gastric torsion after band slippage is extremely rare. Literature review of gastric banding and complications in pregnancy did not reveal any case of gastric torsion. Hence, we report this rare case of gastric torsion in a pregnant lady following gastric banding.

In nanotoxicology, the capacity of nanoparticles of the same composition but different shape to induce cytotoxicity and genotoxicity is largely unknown. A series of cytotoxic and genotoxic responses following in vitro exposure to differently shaped CuO nanoparticles (CuO NPs, mass concentrations from 0.1 to 100 μg/ml) were assessed in murine macrophages RAW 264.7 and in peripheral whole blood f...

Cu electrodeposition was performed on a cylindrical AZ80 substrate with a U-shaped surface. A uniform deposition of Cu was achieved on an AZ80 electrode via galvanostatic etching, followed by Cu electrodeposition in an eco-friendly alkaline Cu plating bath. Improper wetting and lower rotational speeds of the AZ80 electrode resulted in an uneven Cu deposition at the inner upper site of the U-sha...

Copper efflux oxidases (CueOs) are key enzymes in copper homeostasis systems. The mechanisms involved however largely unknown. CueO-type share a typical structural feature composed of Methionine-rich (Met-rich) domains that proposed to be homeostasis. Bioelectrocatalysis using the presence Cu2+ recently highlighted new Cu2+-dependent catalytic pathway related cuprous oxidase activity. In this w...
