An improved electrothermal atomic absorption spectrometric method for determination of aluminum in serum is described. An ammonium hydroxide/sulfuric acid diluent is used to control matrix effects from serum constituents. Because serum produces no apparent matrix effects with this diluent, one can accurately calibrate the procedure with aqueous standards.

These recommendations concern the use of aluminum hydroxide adsorbed cell-free anthrax vaccine (Anthrax Vaccine Adsorbed [AVA], BioPort Corporation, Lansing, MI) in the United States for protection against disease caused by Bacillus anthracis. In addition, information is included regarding the use of chemoprophylaxis against B. anthracis.

In this paper, mesoporous alumina with different pore sizes and wall crystalline structures was synthesized at calcination temperatures over 550 degrees C. The characterization of the samples calcined at 550, 800, 1100, and 1300 degrees C, respectively, was performed using TEM, XRD, FTIR, TG/DTA, and N2 adsorption/desorption techniques. The correlation between pore size and wall crystalline str...

A light scattering model under the Rayleigh-Gans-Debye approximation has been developed for polycristalline alumina. The model states that transmittance of dense alumina ceramics basically depends not only on the maximum grain size but also on the preferential orientation of their c-axis, or texture. The effect of texture in transparency has been experimentally measured on several dense alumina...

OBTAINING AN ELECTRON ENERGY-LOSS SPECTRA FINGERPRINT FOR THE χ AND κ PHASES OF ALUMINUM OXIDE Michael Tanner Department of Physics and Astronomy Bachelor of Science The crystal structure of Al2O3 is found naturally in at least seven different atomic arrangements or phases. By heating gibbsite, an aluminum hydroxide, to different temperatures, the χ, κ, and α phases were obtained. The phase of ...

Aluminum (Al) hydroxide is an effective adjuvant used in sheep vaccines. However, Al-adjuvants have been implicated as potential contributors to a severe wasting syndrome sheep—the so-called ovine autoimmune-inflammatory induced by adjuvants (ASIA syndrome). This work aimed characterize the effects of repetitive injection Al-hydroxide containing products lambs. Four flocks (Flocks 1–4; n = 21 e...

Boron carbide (B4C) added manganese dioxide (MnO2) used as a cathode material for a Zn–MnO2 battery using aqueous lithium hydroxide (LiOH) as the electrolyte is known to have higher discharge capacity but with a lower average discharge voltage than pure MnO2 (additive free). The performance is reversed when using potassium hydroxide (KOH) as the electrolyte. Herein, the MnO2 was mixed with 0, 5...
