Apr 03, 2018 A generalized linear mixed model (GLMM) was used to assess the impact of off-label contact time, concentration, and their interactions for each disinfectant independently (α = 0.05). Bacterial strain type was considered a random variable to determine the effect of contact time and concentration on disinfectant efficacy irrespective of strain type.
Jul 30, 2018 Over the past several decades in the United States, more and more health care providers and health insurers have consolidated, increasing their market power. Highly concentrated markets have contributed to the growth in U.S. health care spending because they are associated with higher health care prices and insurance premiums, yet are not typically associated with higher quality of care.
Apr 01, 2016 Under fluctuating water table conditions, DNAPL TCE sources in the unsaturated zone produced slow response times but high and long-lasting gas concentrations. In contrast, dissolved TCE sources produced relatively weak gas concentrations characterized by a peak, quickly followed by decreasing gas concentration curves.

Sep 05, 2018 Concentration is an expression of how much solute is dissolved in a solvent in a chemical solution.There are multiple units of concentration.Which unit you use depends on how you intend to use the chemical solution. The most common units are molarity, molality, normality, mass percent, volume percent, and mole fraction.

Anchor: #i1107984 Section 11: Time of Concentration. Time of concentration (t c) is the time required for an entire watershed to contribute to runoff at the point of interest for hydraulic design; this time is calculated as the time for runoff to flow from the most hydraulically remote point of the drainage area to the point under investigation.
A. K. Sengupta MET 301: Stress concentration 1/6 2-4: Stress Concentration Caused by Sudden Change in Form A change in the geometric shape of a part gives rise to additional stress over and above the calculated stress, which is known as stress concentration.
The density of a mixture can be converted into a concentration unit using a suitable concentration table or, more generally, a conversion formula. Nearly all binary solutions can be characterized by using density-related functions and concentration tables. These tables may either come from literature or individual experimental data.
