Enhanced diffusion of aluminum in shock activated beryllium has been observed. Cylindrical samples of aluminum coated beryllium rods were axisymetrically loaded up to 40 Gpa and a total residual strain of up to 6.74. The defect microstructure produced by both the shock wave and strain enabled the transport of aluminum in beryll~um to exceed its equilibrium solid state saturation. This "super sa...

Aluminum is abundant in the environment and can also be found in most foods. To date, no convincing data has been found regarding the possible risk of ingesting aluminum through food, water and pharmaceuticals. This paper sought to review current literature to find evidence of the health effects of aluminum absorption in the diet in humans. The review found that the evidence is contradictory an...

This study was designed to determine the effects of an aluminum hydroxide antacid and a calcium carbonate antacid on the bioavailability of ciprofloxacin (Cipro). Cipro (750 mg) was administered orally to 12 healthy volunteers in a three-way randomized crossover design. The three treatments included Cipro alone, four 850-mg calcium carbonate tablets taken 5 min before Cipro, and three 600-mg al...

For nearly a century, aluminum salts have been the most widely used vaccine adjuvant formulation, and have thus established a history of safety and efficacy. Nevertheless, for extremely challenging disease targets such as tuberculosis or HIV, the adjuvant activity of aluminum salts may not be potent enough to achieve protective efficacy. Adsorption of TLR ligands to aluminum salts facilitates e...

Aluminum hydride, a very interesting and valuable reducing agent, has been widely used in numerous applications in organic syntheses. Jorgenson first reported the comparison in the reducing properties between lithium aluminum hydride and aluminum hydride on the reduction of cinnamaldehyde, and Brown and Yoon reported a systematic study on the reducing properties of aluminum hydride in THF. Fina...

Muricidal behavior, weight, open-field activity, passive-avoidance learning, and learning of an eight-arm radial maze were assessed in Long-Evans hooded rats subjected as weanlings to 60 days of oral administration of aluminum hydroxide gel (Group AA) or tap water (Group NA). Measurement of brain aluminum content indicated that the groups did not differ significantly in neural incorporation of ...

Technology of round bars rolling on a three-high skew rolling mills allows rolling of standard materials such as steel and aluminum, as well as new materials, especially hard deformable materials. The paper presents the results of theoretical and experimental rolling process of aluminum bars with a diameter of 20 mm. As the stock round bars with a diameter of 25 mm made of aluminum grade 1050A ...

Aluminum, the most abundant neurotoxic metal in our biosphere, has been implicated in the etiology of several neurodegenerative disorders including Alzheimer's disease (AD). To further understand aluminum's influence on gene expression, we examined total messenger RNA levels in untransformed human neural cells exposed to 100 nanomolar aluminum sulfate using high density DNA microarrays that int...

Efforts to understand how plants respond to aluminum have focused on describing the symptoms of toxicity and elucidating mechanisms of tolerance; however, little is known about the signal transduction steps that initiate the plant's response. Here, we image cortical microtubules and quantify plasma-membrane potential in living, root cells of intact Arabidopsis seedlings. We show that aluminum d...

in recent years, a potential connection between human intake of aluminum and alzheimer’s disease has drawn attention to the aluminum concentration in drinking water. it is therefore of interest to investigate the aluminum concentration m drinking water, produced under different circumstances. a random selection of 152 water samples were taken by the supply source including ground, surface and a...
