Diatom Morphogenesis (Diatoms: Biology and Applications)
by Richard Gordon Vadim Annenkov Joseph SeckbackDIATOM MORPHOGENESIS A unique book presenting the range of silica structures formed by diatoms, theories and hypotheses of how they are made, and applications to nanotechnology by use or imitation of diatom morphogenesis. There are up to 200,000 species of diatoms, each species of these algal cells bearing an ornate, amorphous silica glass shell. The silica is structured at 7 orders of magnitude size range and is thus the most complex multiscalar solid structure known. Recent research is beginning to unravel how a single cell marshals chemical, physical, biochemical, genetic, and cytoskeletal processes to produce these single-cell marvels. The field of diatom nanotechnology is advancing as this understanding matures. Diatoms have been actively studied over the recent 10-20 years with various modern equipment, experimental and computer simulation approaches, including molecular biology, fluorescence-based methods, electron, confocal, and AFM microscopy. This has resulted in a huge amount of information but the key stages of their silica morphogenesis are still not clear. This is the time to reconsider and consolidate the work performed so far and to understand how we can go ahead. The main objective of this book is to describe the actual situation in the science of diatom morphogenesis, to specify the most important unresolved questions, and to present the corresponding hypotheses. The following areas are discussed: A tutorial chapter, with a glossary for newcomers to the field, who are often from outside of biology, let alone phycology; Diatom Morphogenesis: general issues, including symmetry and size issues; Diatom Morphogenesis: simulation, including analytical and numerical methods for description of the diatom valve shape and pore structure; Diatom Morphogenesis: physiology, biochemistry, and applications, including the relationship between taxonomy and physiology, biosilicification hypotheses, and ideas about applications of diatoms. Audience Researchers, scientists, and graduate students in the fields of phycology, general biology, marine sciences, the chemistry of silica, materials science, and ecology.
Diatom Photosynthesis: From Primary Production to High-Value Molecules (Diatoms: Biology and Applications)
by Johann Lavaud Johannes W. Goessling João SerôdioThis comprehensive guide is designed for researchers, professionals, and students looking to deepen their knowledge of diatoms, including detailed information on diatom photosynthesis regulation at the molecular scale, as well as their significant ecological roles, all aimed at promoting sustainable advancements and the safeguarding of aquatic ecosystems. Diatoms exert an immense influence on the ecosystem of Earth due to their remarkable abundance and species diversity. Thriving in diverse habitats spanning the oceans, intertidal benthic zones, saline and freshwater environments, and even terrestrial niches like moist soil, forests, and caves, they play an integral role. Diatoms alone account for around 20% of the oxygen generated by photosynthesis, comparable to the combined productivity of tropical rainforests worldwide, while their primary production can reach 40–45% in marine ecosystems. Nevertheless, in contrast to the extensive research on macroscopic photosynthetic organisms, investigations in this domain remain comparatively limited, despite the role of diatoms in global biogeochemical processes. This book presents an exhaustive review of the subject matter, encompassing a wide spectrum of topics ranging from the intricate molecular mechanisms of diatom photosynthesis and light absorption to the dominant role of diatoms as primary producers within ecological frameworks. Beyond this, the book delves into the practical implications stemming from diatoms and their photosynthetic productivity. A strong emphasis is placed on the importance of fundamental research in deepening our understanding of the natural world around us. Diatoms Photosynthesis provides readers with a comprehensive guide to understanding the fundamentals of diatom photosynthesis and their ecological significance in aquatic ecosystems; a guide to the potential of diatom-derived products for sustainable technologies; a roadmap from diatom photosynthesis to implications in applied sciences; a bridge to span the gap between fundamental research on diatoms and their practical applications. Audience This book caters to academic professionals, students, and researchers in the fields of marine biology, ecology, microbiology, and biochemistry. It offers insights and benefits into diatom photosynthesis, diatom physiology, biodiversity, ecosystem health, and sustainable technological advancements.

Diatoms to Dinosaurs: The Size And Scale Of Living Things
by Christopher Mcgowan Julian MulockIn Diatoms to Dinosaurs, Chris McGowan takes the reader on a fascinating journey through the natural world, and examines life in all its various forms. He imparts the excitement of discovery and the joy of understanding as he demonstrates the central importance of size and scale to the survival of living organisms.McGowan investigates a wide range of size-related phenomena, from the gliding mechanism of diatoms to blood pressure problems of dinosaurs. Questions asked -- and answered -- include: Will we ever see giant insects the size of pterodactyls? Why are ants so much stronger relative to body size than elephants? What do a clam, a condor, a tortoise, and a sturgeon have in common? How did the skeleton of a 28-ton Apatosaurus support its weight? How can blood get from the heart to the head of a giraffe without rupturing blood vessels? The author explicates the scientific concepts -- both physical and biological -- needed to inform the relevant phenomena: area/volume relations, metabolism and other basic physiology, kinetic energy, inertial forces, the biology of senescence, boundary layers, and Reynolds numbers. Numerous illustrations scattered throughout the text make the biophysical principles easily comprehensible to readers, regardless of their scientific sophistication.

Diccionario incompleto de bioética
by Arnoldo KrausEl primer diccionario mexicano de bioética. ¿Debe tener límites el conocimiento? ¿Está usted de acuerdo con el concepto de muerte cerebral? ¿Cuándo piensa usted que empieza la vida de un ser humano? ¿Cómo se debería regular el avance tecnológico para evitar sus consecuencias negativas para el ser humano? Este es el primer diccionario mexicano de bioética y surge del deseo de ofrecer al público interesado un marco de referencia que incluya "la mayoría" de los términos relacionados con esta disciplina. Está en evolución porque los límites de su estudio no se han determinado con precisión y porque, a medida que se avanza en ciertos campos de la ciencia, emergen nuevos temas. Arnoldo Kraus y Ruy Pérez Tamayo presentan los conceptos más importantes y controvertidos que se discuten continuamente en relación con la bioética. Pero no sólo explican cada término sino en qué consiste el problema medular y los distintos puntos de vista que se han planteado. Aborto, clonación, confidencialidad, eutanasia, genoma humano, suicidio... están sencilla y brevemente explicados y algunos van acompañados de preguntas para poner al lector, sin rodeos, en el centro de la polémica. "En su sentido más amplio, la bioética se relaciona no sólo con la biología y con la ética sino con muchas otras áreas de la actividad humana, como la medicina, la ecología, la antropología, la economía, la filosofía, las leyes, la ciencia en general, la tecnología y el desarrollo social, entre otras más. Por esta razón nuestro diccionario podría haber sido mucho más amplio, pero entonces debería haberse llamado Diccionario de bioética y de otras cosas, y seguiría siendo incompleto." -Arnoldo Kraus y Ruy Pérez Tamayo.
