CFD Predictions of Sufficient Suspension Conditions in Solid-Liquid Agitated Tanks

2012

Abstract Most research efforts on mechanically agitated solid-liquid contactors have been devoted to the assessment of the minimum impeller speed for complete off-bottom suspension, N js . Actually, many industrial vessels are operated at impeller speeds slightly lower than N js (Oldshue, 1983; Rieger et al., 1988). This suggests that the sufficient suspension condition, which is quantitatively specified in this paper by introducing a suitably defined quantity N ss , may represent a valid alternative to that of complete suspension. In the present work time-dependent RANS simulations were carried out with the aim of predicting the achievement of sufficient suspension conditions. The Eulerian…

Environmental Stimulus Perception as an Incidence Factor in Social Interaction and Personality Development

2019

This paper seeks to analyze the impact of perceptual process, as a way of perceiving ourselves and others, as well as personality development and social attitudes which emerge from early interactions in the primary environment. Although many studies have highlighted the importance of early social interactions for both the genetic and psychobiological components of personality development, there is actually little data that examines the influence of these genetic factors on this process. This study focuses on the genetic bases of the perception process and its role in how we experience emotions and how we perceive the surrounding environment, starting with early interactions with caregivers.…

Childhood Maltreatment, Pathological Personality Dimensions, and Suicide Risk in Young Adults

2018

Several studies have demonstrated that child maltreatment (psychological, physical, and sexual abuse, and neglect) may be a significant factor in the development of pathological personality traits that increase the risk for suicidal ideation and behavior from adolescence to adulthood. Currently, the challenge is to understand how different forms of early negative experiences render an individual prone to develop specific personality traits and, in turn, be more vulnerable to suicide risk. To understand the relationship between childhood maltreatment and personality dimensions in suicide risk, our study aims to explore the role of self-criticism and dependency, two different pathological per…

2011

La Childhood Experience of Care and Abuse–CECA (Bifulco et al. 1994), recentemente adattata per la popolazione italiana (Giannone, Schimmenti et al. 2011) è considerata il criterio gold standard per la rilevazione delle esperienze di cura ed abuso vissute in età infantile e adolescenziale.

COMPULSIVE BUYING AND ELDERLY MEN: DEPRESSION, COPING STRATEGIES AND SOCIAL SUPPORT

2014

Old age is characterized by great changes that become real challenges that the person must overcome in order to effectively end his evolutionary process. Particulary, the most stressful events for the elderly are the social economic decline, the deterioration of health and the loss of loved ones. It is therefore important to consider the strategies chosen by the elderly person to cope with such tasks; these strategies, if not effective, result in a developmental failure. The objective of this research was to analyze the relantionship among geriatric depression, coping strategies and levels of problematic shopping in elderly male subjects. The research involved 120 men over 60’. The choice o…
