Large racial disparities in completion rates from substance abuse treatment programs in urban settings remain largely unexplained, although evidence is accumulating that neighborhood conditions may influence individual substance abuse patterns and consequences. Understanding racial disparities in alcohol treatment completion, in particular, is crucial to resolving health disparities because rac...

Sustainable glasses were prepared by green technology including the use of different wastes as raw materials and concentrated solar power (CSP) renewable energy. The used to formulate animal bone flour ash, which presents high contents CaO, P2O5 alkaline oxides; glassy sand from waste packaging glass submitted a primary treatment, composed principally SiO2; potassium carbonate reagent grade. Di...

It is very important in the design of a drying system is to evaluate sticking behaviour of the materials goes under drying. A new approach to the sticking issue is applied in this study by carrying out a sticking test for the liquid associated with the materials under study. It was found that the liquid bridge is responsible of the initial sticking of the materials to the contact surface and th...

A pentagonal ring is suggested as the basic structural unit of HCl(H2O)6 and (HCl)2(H2O)6 in solution. Modeled after the X-ray structure of a caged H13O6 compound, it contains bridged H5O2 and Clions, each with a coordination number around four. In the most concentrated HCl solutions, one of the ligands solvating Clis HCl, giving rise to a bichloride moiety. The proposed structure explains qual...

In this paper we address the problem of wave dynamics in presence of concentrated nonlinearities. Given a vector field V on an open subset of C and a discrete set Y ⊂ R with n elements, we define a nonlinear operator ∆V,Y on L (R) which coincides with the free Laplacian when restricted to regular functions vanishing at Y , and which reduces to the usual Laplacian with point interactions placed ...

Case report of a very serious drinking water incident putting up to 50,000 inhabitants of a town near Bonn in North Rhine-Westphalia, Germany at risk. A concentrated solution of highly alkaline water by sodium hydroxide was accidentally washed into the town's drinking water at a pumping station and increased the pH-value of the water to 12. Residents who came into contact with the contaminated ...
