Book Description
Phase and Caste Determination in Insects: Endocrine Aspects is a collection of papers presented at a Symposium of the Section Physiology and Biochemistry of the XV International Congress of Entomology, held in Washington, D.C. in 1976. Contributors explore the endocrine aspects of phase and caste differentiation in insects, with emphasis on the crucial roles of juvenile hormone (JH) and queen bee determinator. This book is comprised of 11 chapters and begins with a discussion on the role of JH in caste formation in honey bees, bumblebees, and termites. Subsequent chapters explore environmental, genetic, and endocrine influences in caste determination in the stingless bee; endocrine control over caste differentiation in higher termites and Myrmicine ants; the influence of external factors on hormone effects in termite caste determination; and the role of JH in the polymorphism of aphids. The final chapter deals with the regulation of aphid polymorphism by neurosecretory cells. This monograph will be a valuable resource for entomologists, endocrinologists, physiologists, and biochemists as well as insect enthusiasts.

Book Description
The present anthology seeks to give an overview of the different approaches to establish a relation between phenomenology and psychoanalysis, primarily from the viewpoint of current phenomenological research. Already during the lifetimes of the two disciplines' founders, Edmund Husserl (1859 - 1938) and Sigmund Freud (1856 – 1939), phenomenological and phenomenologically inspired authors were advancing psychoanalytic theses. For both traditions, the Second World War presented a painful and devastating disruption of their development and mutual exchange. During the postwar period, phenomenologists, especially in France, revisited psychoanalytic topics. Thus, in the so-called second generation of phenomenology there developed an intensive reception of the psychoanalytic tradition, one that finds its expression even today in current hermeneutic, postmodern and poststructuralist conceptions. But also in more recent phenomenological research we find projects concentrated systematically on psychoanalysis and its theses. In this context, the status of psychoanalysis as a science of human experience is discussed anew, now approached on the ‘first person’ basis of a phenomenological understanding of subjective experience. In such approaches, phenomena like incorporation, phantasy, emotion and the unconscious are discussed afresh. These topics, important for modern phenomenology as well as for psychoanalysis, are examined in the context of the constitution of the human person as well as of our intersubjective world. The analyses are also interdisciplinary, making use of connections with modern medicine, psychiatry and psychotherapy. The systematic investigations are enriched by historical analysis and research in the internal development of the disciplines involved. The volume presents recent work of internationally recognized researchers – phenomenologically oriented philosophers, psychoanalysts and psychotherapists – who work in the common field of the two disciplines. The editors hope that this selection will encourage further systematic collaboration between phenomenology and psychoanalysis

Book Description
Receptor Tyrosine Kinase: Structure, Functions and Role in Human Disease, for the first time, systematically covers the shared structural and functional features of the RTK family. Receptor Tyrosine Kinases (RTKs) play critical roles in embryogenesis, normal physiology and several diseases. And over the last decade they have become the Number 1 targets of cancer drugs. To be able to conduct fundamental research or to attempt to develop pharmacological agents able to enhance or intercept them, it is essential first to understand the evolutionary origin of the 58 RTKs and their roles in invertebrates and in humans, as well as downstream signaling pathways. The assembly of chapters is written by experts and underscores commonalities between and among the RTKs. It is an ideal companion volume to The Receptor Tyrosine Kinase: Families and Subfamilies, which proceeds, family by family through all of the specific subfamilies of RTKs, along with their unique landmarks.

Book Description
The author of The Golden Ratio tells the “lively and fascinating” story of two nineteenth-century mathematicians whose work revealed the laws of symmetry (Nature). What do Bach’s compositions, Rubik’s Cube, the way we choose our mates, and the physics of subatomic particles have in common? All are governed by the laws of symmetry, which elegantly unify scientific and artistic principles. Yet the mathematical language of symmetry—known as group theory—did not emerge from the study of symmetry at all, but from an equation that couldn’t be solved. For three centuries, the quintic equation resisted efforts by mathematicians to find a solution. Working independently, two great prodigies ultimately proved that it couldn’t be solved by a simple formula. These geniuses, a Norwegian named Niels Henrik Abel and a romantic Frenchman named Évariste Galois, both died tragically young. Their incredible labor, however, produced the origins of group theory. The first extensive, popular account of the mathematics of symmetry and order, The Equation That Couldn’t Be Solved is told not through abstract formulas but in a dramatic account of the lives and work of some of the greatest mathematicians in history.

Book Description
In medicine the understanding and interpretation of the complex reality of illness currently refers either to an organismic approach that focuses on the physical or to a 'holistic' approach that takes into account the patient's human sociocultural involvement. Yet as the papers of this collection show, the suffering human person refers ultimately to his/her existential sphere. Hence, praxis is supplemented by still other perspectives for valuation and interpretation: ethical, spiritual, and religious. Can medicine ignore these considerations or push them to the side as being subjective and arbitrary? Phenomenology/philosophy-of-life recognizes all of the above approaches to be essential facets of the Human Condition (Tymieniecka). This approach holds that all the facets of the Human Condition have equal objectivity and legitimacy. It completes the accepted medical outlook and points the way toward a new `medical humanism'.

Book Description
Constructional morphology explains features of organisms from a constructional and functional point of view. By means of physical analysis it explains the operational aspects of organic structures - how they can perform the activities organisms are expected to fulfil in order to survive in their environment. Constructional morphology also explains options and constraints during the evolution determined by internal constructional needs, ontogenetic demands, inherited organizational preconditions and environmental clues.

Book Description
This text comprehensively covers the analysis, enzymology, physiology and genetics of valuable natural products used in the food industry that are attractive targets for biotechnological production. The focus is on the recent advances made to achieve this goal. This unique work is the first book to focus on biotechnological production of important natural products in food additives, fragrances and flavorings, and other bioactive compounds in food. The chapters offer a deep insight into modern research and the development of low molecular weight natural products. Biotechnology of Natural Products covers products in the Phenolic, Terpenoid, and Alkaloid categories, providing a full overview of the biotechnology of food additives and other low molecular weight natural products. Gene clustering and the evolution of pathways are covered, as well as future perspectives on the topic. Due to limited oil resources and increasing consumer demand for naturalness, bioprocesses are increasingly needed to meet these requirements. Novel sophisticated technologies have facilitated the elucidation of new chemical molecules, their biosynthetic pathways and biological functions. This book provides researchers with a full overview of the technologies and processes involved in the biotechnology of natural products.
