The flow and heat transfer characteristics of a tetra-n-butyl ammonium bromide (TBAB) hydrate slurry were investigated experimentally. The characteristics in the transition region were examined in detail. Two types of hydrates form from TBAB solution of different concentrations. The hydrate type, Reynolds number and solid fraction were varied as experimental parameters and the coefficients of pipe friction and heat transfer were measured. In the low solid fraction region, it was found that the coefficients of pipe friction and heat transfer were constant and the values were the same as that for turbulent flow of the TBAB solution. However, for the high solid fraction region, a laminarization phenomenon occurs and the flow and heat transfer characteristics can be estimated from the laminar flow of the hydrate slurry. Moreover, the laminarization point for the solid fraction can be predicted using the apparent Reynolds number. © 2012 Elsevier Ltd and IIR. All rights reserved.

A rapid system using terminal restriction fragment length polymorphism (T-RFLP) analysis targeting 16S rDNA is described for microbial population analysis in edible fish samples. The defined terminal restriction fragment database was constructed by collecting 102 strains of bacteria representing 53 genera that are associated with fish. Digestion of these 102 strains with two restriction enzymes, HhaI and MspI, formed 54 pattern groups with discrimination to the genus level. This T-RFLP system produced results comparable to those from a culture-based method in six natural fish samples with a qualitative correspondence of 71.4 to 92.3%. Using the T-RFLP system allowed an estimation of the microbial population within 7 h. Rapid assay of the microbial population is advantageous for food manufacturers and testing laboratories; moreover, the strategy presented here allows adaptation to specific testing applications.

A stable Ca preparation in solution form even at high concentration is provided. The aqueous preparation of Ca includes water, Ca, compounds of Formula I and Formula II. Most of Ca is in non-ionic form and forms a complex. In the complex, Ca binds to the compound(s) of Formula I and/or Formula II in a state that basic structures of them are kept. At least partially, the complex forms colloidal particles. The aqueous preparation is transparent. pH is equal to or higher than that of slightly acid; [A
