phase inversion in liquid-liquid dispersions corresponds to the transitional boundary between oil-in-aqueous dispersion and aqueous-in-oil dispersion. a theoretical model based on simple assumptions was proposed to predict phase inversion point, ambivalence region and the hysteresis effect of inversion. experimental data from the literature were used to validate the model and results were compa...

We propose an extended Ginzburg-Landau model for a description of the ambivalence region associated with the phenomenon of phase inversion observed in dispersed water-oil flow through a pipe. In analogy to the classical mean-field theory of phase transitions, it is shown that a good quantitative representation of the ambivalence region is obtained by using the injected phase volume fraction and...

Moral decisions and social relationships are often characterized by strong feelings of ambivalence which can be a catalyst for emotional distress and several health-related problems. The anterior cingulate cortex (ACC) has been identified as a key brain region in monitoring conflicting information, but the neurobiological substrates of ambivalence processing are still widely unknown. We have co...

an experimental study of the phase inversion behavior of liquid-liquid dispersion has been conducted in a spray extraction column for systems of toluene / water, n-hexane/water, ccl4/water, toluene /water + glycerol (25 % wt), toluene + ccl4 (25 % wt) / water and toluene / acetic acid (5 % wt)/water. the effects of physical properties, mass transfer and column geometry on phase inversion have b...

Research has shown that people who feel powerful are more likely to act than those who feel powerless, whereas people who feel ambivalent are less likely to act than those whose reactions are univalent (entirely positive or entirely negative). But what happens when powerful people also are ambivalent? On the basis of the self-validation theory of judgment, we hypothesized that power and ambival...

The aims of this study were to analyze the differences in the mothers' and fathers' socialization styles depending on their children's sex; whether there are differences in hostile, benevolent, and ambivalent sexism, and neosexism as a function of both parents' socialization styles; and whether the parents' educational level affects their level of sexism and their children's sexism. The sample ...

Ambivalence can be understood as a cyclical movement between two opposing positions of the self: one expressed in a novelty-an innovative moment (IM)-and another one conveyed by a return to the maladaptive pattern. If not properly addressed and resolved during therapy, ambivalence can prevent change and lead to psychotherapeutic failure. Two processes of ambivalence resolution have been suggest...

250 words) CONTEXT: Ambivalence towards pregnancy is a widespread phenomenon with potential importance for understanding contraceptive behavior and measuring unintended pregnancy. Ambivalence may be operationalized as either a neutral attitude toward pregnancy or having conflicting attitudes. Previous research has focused on ambivalence as a neutral attitude, while conflicted ambivalence is les...

We examined the ability of preschool-aged children to identify conflicting, or ambivalent, desire states (e.g., "I want to go to the birthday party because there will be cake, but I also don't want to go because I'm having fun playing at home"). Participants were 4- and 5-year-old children, and a group of undergraduate students (n = 20 in each age group). They were presented with 14 scenarios i...
