OBJECTIVE Beyond the initial relapse episode, little is known about short-term patterns of alcohol and other drug use in treated adolescents. This study characterized treated teens' short-term alcohol and other drug use trajectories over 1-year follow-up. METHOD Adolescents (N = 110, ages 12-18, 65% male, 94% white) recruited from addictions treatment, with a current DSM-IV alcohol diagnosis,...

Analysis of the work, which considered mathematical modeling melting process in various industries, currently does not pay attention to processes heating and hydrocarbon mixtures, such as vaseline, paraffin, fats, lanolin others. The issue optimization processes, calculations necessary parameters (speed depth thermal front penetration, etc.) equipment, avoidance repetition for each mixture expe...

Particle deposition and suspension in a horizontal pipe flow have been studied. A 3D numerical multiphase mixture model available in Fluent 6.0 is used. The model solves continuity and momentum equations for the mixture and volume fraction equations for the secondary phases. Transport equations were also solved for turbulence parameters of the particulate phases. Gravitational and hydrodynamic ...

BACKGROUND This paper describes a conceptual framework for solutions-focused management of chemical contaminants built on novel and systematic approaches for identifying, quantifying and reducing risks of these substances. METHODS The conceptual framework was developed in interaction with stakeholders representing relevant authorities and organisations responsible for managing environmental q...

Agency for Toxic Substances and Disease Registry (ATSDR) utilizes chemical-specific minimal risk levels (MRLs) to assist in evaluating public health risks associated with exposure to hazardous substances. The MRLs are derived based on the data compiled from current worldwide literature searches and presented in ATSDR's toxicological profiles. These documents profile not only individual chemical...

This paper deals with a three-dimensional mixture model describing materials undergoing phase transition with thermal expansion. The problem is formulated within the framework of generalized standard solids by the coupling of the momentum equilibrium equation and the flow rule with the heat transfer equation. A global solution for this thermodynamically consistent problem is obtained by using a...

The explosive atmosphere may be caused by flammable gases / vapours or combustible dust. If the amount of substance, mixed with air, is sufficient, then a source ignition needed to cause an explosion. Liquids (for example petrol and other fuels) solvents from industrial products emit which, when can ignite explode. At normal temperatures, liquids enough form mixtures heat, often thick, black, t...

In this work, we extend the pure fluid crossover statistical associating fluid theory (HRX-SAFT) equation of state (EOS) (Kiselev et al., Fluid Phase Equilib. 2001, 183-184, 53) to fluid mixtures of polar and associating components. HRX-SAFT incorporates non-analytic scaling laws in the critical region and is transformed into the analytical, classical HR-SAFT EOS far away from the critical poin...

Background Previous animal studies showed that partial whey hydrolyates could prevent acute allergic symptoms in a mouse model for cow’s milk allergy. This effect was even more pronounced in combination with a diet containing a specific non-digestible oligosaccharide mixture of scGalacto(scGOS), lc-Fructo(lcFOS) and Acidic(pAOS) oligosaccharides (in a 9:1:2 ratio). We hypothesized that these hy...
