Studying the factors influencing the process of nanosilver particle formation, it was shown that the particle size of the nanosilver products depends on the concentration of the reaction components and their stoichiometric ratio. It was also shown that the reaction system using AOT surfactant is capable of producing nanosilver particles with smallest nanoparticles (phiav ~ 5 nm) and good particle-size distribution. The study on bactericidal activity of the nanosilver products indicated that the disinfecting solution with a nanosilver concentration of 3 ppm was able to inhibit all E.coli and Coliforms, TPC and fungi at 15 ppm, while Vibrio cholerae cells were inactivated completely with 0.5 ppm of nanosilver after 30 minutes exposition.

The model is calibrated to a model admissible Vietnamese data set benchmarked to 1997.

A model for the calculation of systematic errors is given by simulating the measurement system. The calculated values are in good agreement with the experimental values. This confirms the validity of the model and proofs the good performance of this technique in practice. These results may provide guidelines for setting up a measuring system for the assay the radwaste drums.

Tumors were stratified into three categories based on the percentage of nuclei expressing pRb: (a) 0, 0% of tumor cells showing nuclear reactivity; (In \+, 1-50% of tumor cells showing nuclear reactivity; and (c)2+, >50% of tumor cells showing nuclear reactivity. Cases with undetectable (pRb 0) and high (pRb 2+) pRb reactivity had identical rates of recurrence. These cases had significantly higher recurrence (P = 0.0001) and lower survival rates i/' = 0.0002) compared to cases with moderate (pRb 1+ ) pRb reactivity, indicating that high levels of pRb expression may reflect a dysfunctional (altered) Rb pathway. The tumors were also examined for alterations in p53 expression; patients with tumors altered in both p53 and pRb had signifi cantly increased rates of recurrence (P < 0.0001) and survival (P < 0.0001) compared to patients with no alterations in either p53 or pRb; patients with alterations in only one of these proteins had intermediate rates of recurrence and survival. These results suggest that: (a) bladder cancers with high pRb expression do not show the tumor suppressor effects of the protein; and (In alteration in both p53 and pRb may act in cooperative or synergistic ways to promote tumor progression.

They created a favorable trade balance with Jamaica and the British. They created a network of villages that supported the growth of their collective identity through borrowed culture from Africa and Europe and through created culture unique to Maroons. They were self-sufficient and practiced sustainable agricultural practices.
