Transport Processes in Chemically Reacting Flow Systems discusses the role, in chemically reacting flow systems, of transport processes—particularly the transport of momentum, energy, and (chemical species) mass in fluids (gases and liquids). The principles developed and often illustrated here for combustion systems are important not only for the rational design and development of engineering equipment (e.g., chemical reactors, heat exchangers, mass exchangers) but also for scientific research involving coupled transport processes and chemical reaction in flow systems. The book begins with an introduction to transport processes in chemically reactive systems. Separate chapters cover momentum, energy, and mass transport. These chapters develop, state, and exploit useful quantitative ""analogies"" between these transport phenomena, including interrelationships that remain valid even in the presence of homogeneous or heterogeneous chemical reactions. A separate chapter covers the use of transport theory in the systematization and generalization of experimental data on chemically reacting systems. The principles and methods discussed are then applied to the preliminary design of a heat exchanger for extracting power from the products of combustion in a stationary (fossil-fuel-fired) power plant. The book has been written in such a way as to be accessible to students and practicing scientists whose background has until now been confined to physical chemistry, classical physics, and/or applied mathematics.
Developmental Trauma offers a comprehensive introduction to the research findings that help us understand the effects on human development of early childhood trauma and adaptation to stress. It explains how DTD differs from PTSD and emerges from a toxic seed planted at the beginning of an individual’s lifespan development. This important volume examines relational traumas and adverse childhood experiences, such as exposure to family and community violence, polyvictimization (multiple repeated childhood traumas), and disruptions to parent-child bonds, which lay the foundation for future relationships. The volume considers how DTD affects self-regulation capacities, identity development, self-esteem, and faith in oneself and others and increases the likelihood of comorbidities including ADHD and autism spectrum disorders. Individuals with indications of developmental trauma face lifelong challenges in their ability to develop and maintain trusting relationships, to build and utilize healthy coping strategies, and to adjust to school and, eventually, the workplace. Uniquely, Daniel Cruz goes beyond individual levels of analysis that focus almost exclusively on patients and explores toxic stress embedded in social systems and institutional policies and procedures that cause individuals to suffer, experience psychiatric and medical problems, and that lead to social and economic adversities such as poverty, homelessness, and involvement in criminal activity. Key topics explored include institutional betrayal, such as sexual assaults and workplace bullying, and judicial betrayal when failures from the legal system do not adequately protect victims of trauma, for example in cases of domestic violence. Developmental Trauma is for students of child and adolescent psychology, developmental psychology, clinical psychology, primary care and health psychology, education, social work, and urban studies. It is relevant for graduate students in applied fields such as clinical and counseling psychology, and those working with diverse children as well as public health and policy.
I wrote this book urged by the overwhelming desire that arises towards the end of life to recapitulate the past. My goal was to summarize my experience of practicing science at the end of the 20th and early 21st centuries in Argentina, a country located far away from the world’s leading scientific centers. In the book, I summarize the intricacies of the pineal gland (“the stone of madness”) as historical, mystical and medical entity and its entry in contemporary medicine with the description of melatonin. I also reflect on how being associated with an unexplored subject at the beginning of his scientific career impacts the life of a scientist throughout their entire life. Today we know that in humans pineal melatonin is released every day late in the evening, and there is evidence that it is the trigger for the sleep process. But the most exciting aspect of melatonin is that it is a substance that is present in all living creatures, from unicellular organisms to plants and higher mammals, a fact that evinces its importance for life. Further, the neuroprotective action of melatonin promises to be crucial for the control of neurodegenerative diseases we face as a pandemic in this century. The discoverer of melatonin, Aaron Lerner, based its name on melano, the Greek word for black, because of its effect on the pigment cells of the skin. As in "La vie en rose", the immortal Edith Piaf song written in 1946, my lifelong work with melatonin could well be called "Ma vie en noir".
