Bubble Formation through Reaction at Liquid‐Liquid Interfaces

Slag foaming is an important phenomenon in steelmaking processes with both beneficial as well as negative effects. The present work is part of the wider project on the modelling of slag foaming, with special reference to dynamic conditions. Since bubble formation is the first step to foam formation, the present work was carried out in an attempt to simulate the bubble formation in slag/metal reactions in steelmaking processes by water‐modelling experiments. The bubble formation due to the gas produced through chemical reaction at the interface between oleic acid and sodium bicarbonate solution was systematically monitored. The chemical reaction rate was varied by varying the concentration of sodium bicarbonate. The bubbles were observed to be generated in the heavier aqueous phase just below the water‐oil interface. The bubbles penetrated the interface and escaped through the oil phase. The rate of the reaction was estimated from the volume of the gas that passed the water/oil interface. It was observed that the bubble formation and bubble growth mechanism were influenced by the reaction rate while the bubble size seemed to be unaffected by the reaction rate.     

Creating Space: The Fourfold Dynamics of Potential Space.

Winnicott conceived of potential space primarily in terms of the vicissitudes of illusion and reality. Loosened from its ties to illusion and reality, potential space is depicted in terms of 4 interrelated, dialectical processes (surrender-generation, recognition-negation, care-quiescence, and disruption-repair), which can be found, in part, in Winnicott's formulations. Reformulating potential space in terms of these fourfold pairs captures the complexity and paradox of the presence and absence of self-states in successful and failed developmental and psychoanalytic interactions. In addition, these 4 interpersonal dynamics more adequately extend the concept of potential space to all phases of human life. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Construct validation of the Rorschach Reality-Fantasy Scale in alexithymia.

The study applies Winnicott's conceptualization of potential space to the alexithymia construct by using a new Rorschach index, the Reality-Fantasy Scale (RFS). The scale uses variables derived from the Rorschach Comprehensive System (Exner, 2000, 2001) to detect different types of psychopathological manifestations conceptualized as forms of collapse of potential space. Following previous research, the present study further evaluates the construct validity of the RFS in a sample of 92 patients with inflammatory bowel disease, categorized on the basis of the Toronto Alexithymia Scale (TAS-20) as alexithymic, indeterminate alexithymia, and nonalexithymic groups. As hypothesized, the RFS significantly correlated with the TAS-20, discriminated among the 3 groups, and showed incremental validity in detecting alexithymia over isolated Rorschach markers. The study supports the exploration of psychoanalytic ideas by empirical, statistically based methods. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Electronic energy-density effects in ion tracks of metals

High resolution Auger-electron spectroscopy has been applied to the interaction of swift heavy ions with atomically clean metallic solids. Spectra have been taken for fast projectile electrons and for charge-state equilibrated ions at normal incidence on microcrystalline beryllium samples, Al(1 0 0) single crystals and several metallic glasses (Al₈₇La₇Ni₅Zr₁, Ni₇₈B₁₄Si₈, Co₆₆Si₁₆B₁₂Fe₄Mo₂). From the energy shift and from the Auger-line width we have extracted ion-track potentials and also electron temperatures inside ion tracks. A first determination of the angular distribution of multiple-ionization lines is presented as well.

为了生产含低硫、色度好的柴油产品，采用计算机分子模拟技术研究了柴油馏分深度加氢脱硫(HDS)过程中多环芳烃有色体的形成机理。研究结果显示，柴油馏分中难脱除硫化物4-MDBT、4，6-DMDBT的HDS中间产物生成多环芳烃的反应历程中每步反应的活化能较低，其中的缩合环化反应为吸热反应。模拟产物符合实验事实，表明模拟计算的多环芳烃有色体形成路径是可能的、合理的。     

Nonlinear Inverse Boundary-Value Problems of Conformal Mapping with a Controlling Potential

Some characteristic cases of formation of an ideal flow are described depending on preset values of controlling potential. Based on the modified G. Polozhii's method of summary mappings, the characteristic function of the flow is obtained. Examples of construction of a dynamic grid, field of velocities, and formation of different flows are given. Types of key problems of finding the values of controlling potential, which provide optimization of definite functionals are defined. An example of solution to one of them is presented.     

Lateralization of Spatial Learning in the Avian Hippocampal Formation.

The authors investigated lateralization of spatial learning within the avian hippocampal formation (HF). In Experiment 1, homing pigeons (Columba livia) with unilateral lesions of the right or left HF were trained to locate a goal in a square room containing local landmarks and global room cues. All groups learned the task. During probe trials, when landmarks were rotated or removed, intact pigeons and left HF-lesioned pigeons relied exclusively on global room cues to locate the food goal. Pigeons with right HF lesions were the only group to demonstrably use the landmarks. The results suggest that the right HF is preferentially involved in the representation of global environmental space, whereas only the left HF may be sensitive to local landmarks for navigation.
