Effects of oral administration of NC-1100 on the metabolism of neuro active amino acids in rat brain were studied using stroke-prone spontaneously hypertensive (SHR-SP) and Wistar Kyoto rats. The repeated administration of NC-1100 induced a significant increase of r-aminobutyric acid (GABA) content in the cerebellum and medulla oblongata of SHR-SP. The decrease of aspartic acid contents in the ...

The expanding ring test of Grady and Benson (1983) is taken as a convenient yet challenging validation problem for assessing the fidelity of cohesive models in situations involving ductile dynamical fracture. Attention has been restricted to 1100-0 aluminum samples. Fracture has been modelled by recourse to an irreversible cohesive law embedded into cohesive elements. The finite element model i...

Hydrocode simulations were conducted to analyze the non-linear response of 1100-O aluminum plates with semi-circular notches. Plates with constant notch depth and notch root radius were loaded (normal to the notch-tip plane) to the same shock stress while the notch spacing was varied. The resulting stress distributions were analyzed at specific locations between adjacent notches and then the ma...

The expanding ring test of Grady and Benson [20] is taken as a convenient yet challenging validation problem for assessing the delity of cohesive models in situations involving ductile dynamical fracture. Attention has been rescricted to 1100-0 aluminum samples. Fracture has been modelled by recourse to an irreversible cohesive law embedded into cohesive elements. The nite element model is thre...

A multi-year effort has been focused on optimizing the long-term oxidation performance of ingot-processed (IP) and oxide-dispersion strengthened (ODS) Fe3Al and iron aluminidebased coatings. Based on results from several composition iterations, a Hf-doped alloy (Fe28Al-2Cr-0.05at.%Hf) has been developed with significantly better high temperature oxidation resistance than other iron aluminides. ...

So far, two species of Neotherina Dognin have been recorded in Costa Rica. Neotherina imperilla (Dognin) occurs primarily at altitudes between 1100 and 1700 meters and Neotherina callas (Druce) which is widely distributed above 1100 meters. A third, new species, Neotherina xanthosa Sullivan and Chacón is described from altitudes above 2400 meters. Heterogeneity of the genus is discussed.

Accumulative roll bonding is a severe plastic-forming process proposed to manufacture ceramic particle-reinforced multilayered metal matrix composites. In this work, low-cost composite laminate was produced by commercially pure aluminum 1100 with 5% in volume of reinforcing microscale silicon carbide particles. Microstructural features, hardness, tensile properties the presence stress concentra...

As a typical representative of micro/nano-textured silicon, black silicon has excellent light absorption properties and is gradually surfacing as substitute for standard in photoelectric devices. Black overcomes the limitations traditional silicon-based devices, which are unable to achieve infrared detection at wavelengths >1100 nm have low quantum efficiency sensitivity ultraviolet detectio...

Abstract The shape of the projectile seems to determine effect a ballistic impact and failure mechanism. In this study, numerical analysis with different shapes, i.e ., ogive, blunt, conical, hemispherical is performed. target circular sandwich plate an outer diameter 315 mm, which composed three layers thickness 1 mm for each layer. These will be filled materials such as 1100-H12 aluminum allo...

Interactions between fluorine (as F) and aluminum (as Al) have recently attracted much attention following reports of their possible involvement in Alzheimer’s disease (AD). An inverse correlation has been demonstrated between the incidence and severity of AD and the level of fluorine in drinking water.1-4 Aluminum has long since been implicated in the etiopathology of AD, and neurotoxicity stu...
