The conductivity behavior of doped hydrocarbon systems is studied by applying impedance spectroscopy. In the case of 3,5-diisopropyl salicylato aluminum (III) the charge carriers are formed by dissociation of the compound and their concentration is proportional to the square root of the solute concentration. In hydrocarbon systems that consist of micelle forming compounds (sodium AOT/ lecithin)...

Dissociative recombination (DR) of the dimer ion (NO)(2) (+) has been studied at the heavy-ion storage ring CRYRING at the Manne Siegbahn Laboratory, Stockholm. The experiments were aimed at determining details on the strongly enhanced thermal rate coefficient for the dimer, interpreting the dissociation dynamics of the dimer ion, and studying the degree of similarity to the behavior in the mon...

A B S T R A C T The extent of dissociation of various hemoglobins into subunits was estimated from their elution volumes (V.) on G-100 Sephadex. Under the same controlled conditions carboxyhemoglobins A, A3 (A,), F, S, and C all had the same elution volumes. The carboxy and cyanmet derivatives of hemoglobin Kansas (a variant with very low oxygen affinity) had a relatively high Ve, indicating a ...

water soluble chitosan oligosaccharide (cho) was hydrophobically modified with camptothecin (cpt) in different molar ratios of cpt, and characterized by ft-ir and 1 h-nmr spectroscopy. nanomicelles prepared by these copolymers were analyzed for size, zeta, and length of time they remain stable. the critical micelle concentration (cmc) and dissociation of micelles at physiological ph and acidic ...

This is the 1st study to examine peritraumatic dissociation and peritraumatic emotions as they predict symptoms and diagnosis of posttraumatic stress disorder (PTSD) in Latino youth. Our aim was to test the hypothesis that the degree of peritraumatic dissociation would predict the number of PTSD symptoms and PTSD clinical diagnosis when the influences of other salient factors were statistically...

The dissociation of the subunits of human adult oxyhemoglobin has been investigated by using steady-state fluorescence anisotropy, multifrequency phase fluorometry, and high hydrostatic pressure. Human hemoglobin obtained by using two purification procedures (bulk preparation by centrifugation or further fractionation using anion-exchange chromatography) was labeled with an extrinsic fluorescen...

Abstract Non-pathological dissociative experiences are common among the general population, and anyone may experience them to some degree. Thus, aim of this study was assess degree such as fantasy proneness, imagination, absorption in fine arts undergraduates prior beginning their artistic studies, at end studies faculty arts. Moreover, education were used a comparison group. The sample consist...

We analyze the response of molecular adhesion complexes to increasing pulling forces (dynamic force spectroscopy) when dissociation can occur along either one of two alternative trajectories in the underlying multidimensional energy landscape. A great diversity of behaviors (e.g., nonmonotonicity) is found for the unbinding force and time as a function of the rate at which the pulling force is ...
