Two-Fluid Model Stability, Simulation and Chaos
by Martín López de Bertodano William Fullmer Alejandro Clausse Victor H. RansomThis book addresses the linear and nonlinear two-phase stability of the one-dimensional Two-Fluid Model (TFM) material waves and the numerical methods used to solve it. The TFM fluid dynamic stability is a problem that remains open since its inception more than forty years ago. The difficulty is formidable because it involves the combined challenges of two-phase topological structure and turbulence, both nonlinear phenomena. The one dimensional approach permits the separation of the former from the latter. The authors first analyze the kinematic and Kelvin-Helmholtz instabilities with the simplified one-dimensional Fixed-Flux Model (FFM). They then analyze the density wave instability with the well-known Drift-Flux Model. They demonstrate that the Fixed-Flux and Drift-Flux assumptions are two complementary TFM simplifications that address two-phase local and global linear instabilities separately. Furthermore, they demonstrate with a well-posed FFM and a DFM two cases of nonlinear two-phase behavior that are chaotic and Lyapunov stable. On the practical side, they also assess the regularization of an ill-posed one-dimensional TFM industrial code. Furthermore, the one-dimensional stability analyses are applied to obtain well-posed CFD TFMs that are either stable (RANS) or Lyapunov stable (URANS), with the focus on numerical convergence.

Two Hybrid Technologies
by Bernhard Suter Erich E. WankerProtein-protein interactions (PPIs) are strongly predictive of functional relationships among proteins in virtually all processes that take place in the living cell. Therefore, the comprehensive exploration of interactome networks is one of the major goals in systems biology. The aim of Two Hybrid Technologies: Methods and Protocols is to provide a compendium of state-of-the art protocols for the investigation of binary PPIs with the classical yeast two-hybrid (Y2H) approach, Y2H variants and other in vivo methods for PPI mapping. Divided into two convenient sections, the first gives a survey of protocols that are currently employed for Y2H high-throughput screens by different expert labs in the field. Rather than detailing the principles of screening, which have been described previously, the focus is on different implementations of Y2H interactome mapping. The second section of the book considers innovative PPI detection methods that have the potential to emerge as alternative high-throughput methodologies. Written in the highly successful Methods in Molecular BiologyTM series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and accessible, Two Hybrid Technologies: Methods and Protocols supplies researchers with a comprehensive toolbox for the identification of biologically relevant protein interactions.
The Two Lives of Cheng Maolan: From the "French Silk Road to Astronomy" to the Meanders of Mao’s China (SpringerBriefs in Astronomy)
by Thierry Montmerle Yi Zhou Yves GomasThis book presents the exceptional biography of the 20th century Chinese astronomer Cheng Maolan, who came to France in 1926 on a China-France cooperation program to do his PhD with the idea of returning to China after a few years. Instead, he lived two lives. He first stayed in France and studied astronomy in Lyon, the “Silk city”, where he suffered the hardships of the German occupation, but also witnessed the construction of the Haute-Provence Observatory. After the war, he started a promising career at Lyon Observatory. However, in 1957 he decided to live a second life, by returning to the motherland, which had in the meantime become the People's Republic of China. There, he suffered the hardships of the Cultural Revolution, but he managed to play a pivotal role in establishing the Beijing Observatory as its director. In particular, he prepared the ground for the Xinglong 2-m telescope, which saw its first light in 1989, ten years after his death. Cheng Maolan is now considered a "Chinese hero": an "Astronomy and Technology Museum" was built and named after him in 2018, in his native city of Boye, Hebei Province, China, featuring a tall, white statue in front of the building.

Two-Phase Gas-Liquid Flow in Pipes with Different Orientations (SpringerBriefs in Applied Sciences and Technology)
by Afshin J. GhajarThis book provides design engineers using gas-liquid two-phase flow in different industrial applications the necessary fundamental understanding of the two-phase flow variables. Two-phase flow literature reports a plethora of correlations for determination of flow patterns, void fraction, two- phase pressure drop and non-boiling heat transfer correlations. However, the validity of a majority of these correlations is restricted over a narrow range of two -phase flow conditions. Consequently, it is quite a challenging task for the end user to select an appropriate correlation/model for the type of two-phase flow under consideration. Selection of a correct correlation also requires some fundamental understanding of the two-phase flow physics and the underlying principles/assumptions/limitations associated with these correlations. Thus, it is of significant interest for a design engineer to have knowledge of the flow patterns and their transitions and their influence on two-phase flow variables. To address some of these issues and facilitate selection of appropriate two-phase flow models, this volume presents a succinct review of the flow patterns, void fraction, pressure drop and non-boiling heat transfer phenomenon and recommend some of the well scrutinized modeling techniques.

The Two-Photon Decay of the 11-/2 Isomer of 137Ba and Mixed-Symmetry States of 92,94Zr and 94Mo
by Christopher WalzThis work focuses on new electromagnetic decay mode in nuclear physics. The first part of the thesis presents the observation of the two-photon decay for a transition where the one-photon decay is allowed. In the second part, so called quadrupole mixed-symmetry is investigated in inelastic proton scattering experiments. In 1930 Nobel-prize winner M. Goeppert-Mayer was the first to discuss the two-photon decay of an exited state in her doctoral thesis. This process has been observed many times in atomic physics. However in nuclear physics data is sparse. Here this decay mode has only been observed for the special case of a transition between nuclear states with spin and parity quantum number 0+. For such a transition, the one-photon decay - the main experimental obstacle to observe the two-photon decay - is forbidden. Furthermore, the energy sharing and angular distributions were measured, allowing conclusions to be drawn about the multipoles contributing to the two-photon transition. Quadrupole mixed-symmetry states are an excitation mode in spherical nuclei which are sensitive to the strength of the quadrupole residual interaction. A new signature for these interesting states is presented which allows identification of mixed-symmetry states independently of electromagnetic transition strengths. Furthermore this signature represents a valuable additional observable to test model predictions for mixed-symmetry states.
The Two Sexes: Growing Up Apart, Coming Together
by Eleanor Maccoby"This book is about sex (or gender) in the broadest sense: about how an individual's development from infancy into adulthood is affected by being either a male or a female. Although some individuals are hermaphrodites, the vast majority of human beings are biologically clearly either male or female. And, again in the vast majority of cases, the sex identity assigned to an individual by society, as well as the sex identity adopted by the individual, corresponds to the person's biological sex. This book will be concerned with the development of people who are unambiguously members of one gender category or the other. In many respects, males and females take quite similar developmental paths. But in some important respects, their paths diverge. In this book I begin by showing that when boys and girls are engaged in social play, they congregate primarily with others of their own sex during the preschool and middle-childhood years, and that different childhood "cultures" prevail in these gender-segregated playgroups. I will consider the set of possible reasons why this divergence occurs, and discuss the implications of childhood divergence for the ways in which males and females interact when the two sexes converge in adolescence and adulthood. In particular, I will consider how the different social histories of the two sexes affect the relationships of heterosexual couples, the way men and women relate to each other as co-parents, and the nature of same-sex and cross-sex interactions that occur in the workplace."
