To promote the understanding and development of steam diluted H2/air combustion technology, chemical effect dilution on NO formation in 1D laminar premixed flame is numerically studied over a wide range conditions. The importance influence path are analyzed, impact working conditions explored. This research makes up for deficiencies dilution, has significant reference value optimizing practical...

The oxidation of ferrous iron (Fe2+) in solution using Acidithiobacillus ferrooxidans has industrial applications exclusively in the regeneration of ferric iron (Fe3+) as an oxidizing agent for the removal of hydrogen sulfide from waste gases, desulfurization of coal, leaching of non-ferrous metallic sulfides and treatment of acid mine drainage. The aim of this investigation was to increase the...

The enzymatic hydrolysate of wastepaper was evaluated for its cellulase-inducing capability and production characteristics in continuous culture of Trichoderma reesei RUT C30. Under the study conditions, i.e., pH 5.0, temperature 25 degreesC, and typical medium C:N ratio, the apparent cell yield constant was found to be 0. 76 (g of dry cell weight/g of reducing sugar), and the maximum specific ...

Dry areas near the sea can obtain fresh water through solar distillation of saline sea water resources. However, these solar distillation sites produce wastewater as a result of desalination of sea water with high salt concentration. Waste must be disposed of with the least effect on the receiving environment (sea, in most cases). Initial dilution and its characteristics play important roles in...

23 We compared the efficiency of different drug susceptibility testing methods to detect 24 the rifampin (RIF) heteroresistance in Mycobacterium tuberculosis. Our data revealed 25 that broth dilution method found more resistance than MGIT (P=0.046) for low 26 resistance group. Similarly, broth dilution method was more sensitive to detect RIF 27 heteroresistance in subpopulation with slow grow r...

The distortion of indicator dilution curves by catheter sampling systems is predictable from theoretic considerations based on laminar flow. Over a wide range of catheter and flow parameters, deductions can be made regarding distortion, by the arterial system or by sampling catheters, of indicator dilution curves coming from an idealized pump. A figure of merit for the sampling system is given ...

To quantify kinetics of mammary glucose utilization in vivo, 24 paired glucose and extracellular indicator (p-aminohippuric acid) dilution curves across intact bovine mammary glands were obtained after bolus injections into the external iliac artery. Dilution curves were analyzed using a compartmental capillary, convolution integration model. Four candidate submodels of glucose transport and me...
