We theoretically and experimentally examine the e ects from adding a simple, empirically relevant action to a repeated partnership, the option to walk away. Manipulating both the value of the outside option, and its relative distribution among the partners, we examine the strategies selected by human subjects in a simple prisoners-dilemma-like partnership. Our ndings indicate that selecting bet...

Understanding the dissolution behavior of dense non-aqueous phase liquids (DNAPLs) in rock fractures under different entrapment conditions is important for remediation activities and any related predictive modeling. This study investigates DNAPL dissolution in variable aperture fractures under two important entrapment configurations, namely, entrapped residual blobs from gravity fingering and p...

The constitutive relationships required for the parameterization of multiphase flow and transport problems are of critical importance to hydrologic modeling. Recently, a hypothesis has been developed that predicts a functional relationship between capillary pressure, saturation, and interfacial area. A network model was developed to test this hypothesis. Microscale physical processes were simul...

Experimental investigations were undertaken in batch kinetic systems, for the removal of iron (II) from aqueous solutions using activated dolomite. The effect of the extent dolomite activation on the dissolution of magnesium and calcium from the dolomite lattice was determined. Under optimum experimental conditions there was a direct linear relationship between magnesium dissolution and iron (I...

Descriptive statistics indicate that civil marriages and marriages preceded by premarital cohabitation are more unstable, i.e., more frequently followed by divorce. However, the literature has shown that selectivity plays an important role in the relationship between premarital cohabitation and union dissolution. We do not have evidence to date regarding the selectivity in the effect of civil m...

Drug product performance testing is an important part of quality-by-design approaches, but this process often lacks the underlying mechanistic understanding of the complex interactions between the disintegration and dissolution processes involved. Whereas a recent draft guideline by the US Food and Drug Administration (FDA) has allowed the replacement of dissolution testing with disintegration ...

Producing stable nanocrystals confined to porous excipient media is a desirable way to increase the dissolution rate and improve the bioavailability of poorly water soluble pharmaceuticals. The poorly soluble pharmaceutical fenofibrate was crystallized in controlled pore glass (CPG) of 10 different pore sizes between 12 nm and 300 nm. High drug loadings of greater than 20 wt% were achieved acro...

Past research has identified several communication strategies that are used to end relationships (e.g., Baxter, 1982). The present study extends this research by considering how young adults’ propensity to experience compassionate love for a romantic partner is associated with their reported use of breakup strategies. A sample of US university students (n 1⁄4 343) who had initiated the breakup ...

Curcumin is a phytoconstituent with wide range of biological activity. It is poorly soluble in water. In the present study a new dissolution medium was developed, as there is no validated dissolution method available in the literature. The composition of the dissolution medium was selected on the basis of solubility data at 37 degrees . Solubility data revealed that addition of surfactant may b...

The aims of the study were to observe the dissolution profile of four types of selected fruit powder fast dissolve tablet and apply different dissolution profile comparison methods, in order to select most applicable method. Spray dried powder of pitaya, pineapple, guava and mango were used as raw material. Each type of fruit powder tablet has identical dissolution profile. Dissolution profiles...
