dynamic frothability index (dfi) is a characteristic of any frother which presents useful information about frothing properties. the objective of this study is to introduce a prediction model for estimation of dfi value of dual-frother blends. model uses the dfis of frothers and mole ratio of weaker frother to calculate the blend’s dfi. the model reliability was confirmed by comparing the exper...

In order to enhance the compatibilization and interfacial adhesion between epoxy and liquid carboxyl-terminated butadiene acrylonitrile (CTBN) rubber, an initiator was introduced into the mixture and heated to initiate the cross-linking reaction of CTBN. After the addition of curing agents, the CTBN/epoxy blends with a localized interpenetrating network structure were prepared. The mechanical p...

Immiscible homopolymers are often blended mechanically to obtain blends with properties significantly superior to those of the component polymers. The creep recovery of such blends was studied in the previous paper, henceforth referred to as I. Surface-active compatibilizers are commonly added to such blends to improve blending of the immiscible phases and to improve the mechanical properties o...

The objective of these experiments was to measure in vitro hydrolytic digestion and glycemic and insulinemic responses of select carbohydrate blends, all containing the novel carbohydrate soluble corn fiber (SCF). Two SCF that varied in their method of production were used to formulate the carbohydrate blends. One set of blends contained a SCF that was spray dried (SCFsd) and then blended with ...

The chemical properties of six blends of coconut and sesame oils, and the organoleptic qualities of the blends and foods prepared with them were studied. The blends prepared for testing were: (1) 100% coconut oil; (2) 90 % coconut and 10 % sesame; (3) 75 % coconut and 25 % sesame; (4) 50 % coconut and 50 % sesame; (5) 25 % coconut and 75 % sesame; and (6) 100 % sesame oil. In sensory evaluation...

The color of the blends of pre-colored fibers depends on the ratio of each fiber in the blends. Some theories have been introduced for color matching of blends of pre-colored fibers. Most however, are restricted in scope and accuracy. Kubelka and Munk presented the most applicable theory, which is still used in industry. In this work, the classical Kubelka-Munk method for color prediction of a ...

Captures of male dogwood borer, Synanthedon scitula (Harris), in traps baited with trinary andbinaryblendsof the female sexpheromonecomponentswere comparedwith those in traps baitedwith themost effective commercially available lure in apple orchards inWestVirginia, Virginia, and North Carolina. Traps baited with the trinary blend [88:6:6 vol:vol:vol (Z,Z)-3,13 octadecadienyl acetate (ODDA):(E,Z...
