An accessible guide for vegan, vegetarian, or veg-curious parents from the dietitian duo behind online community Plant-Based Juniors®--includes a bonus chapter on feeding infants up to six months! More of us are turning to plant-focused diets for our health and the health of the environment. But there haven't been reliable, evidence-based resources out there for a new generation of compassionate, conscientious parents--until now. The Plant-Based Baby and Toddler is your go-to resource, offering easy-to-digest nutritional facts and guidelines that aren't available elsewhere, with a special focus on the most important period of a child's life when it comes to developing good eating habits: infancy and toddlerhood. Whitney and Alex discuss: • the PB3 plate: a visual guide to structuring meals that are nutritionally balanced--1/3 fruits and vegetables; 1/3 legumes, nuts and seeds; and 1/3 grains and starches--and easy to adapt for the entire family • how to meet needs for critical nutrients such as iron • a primer on both traditional purees and the baby-led weaning/feeding approach • strategies for dealing with challenges such as picky eaters • sorting fact from fiction when it comes to nondairy milks and other substitutes • 50+ plant-based recipes created specifically for stages from first bites to age three As dietitians and moms, Whitney and Alex pored over nutrition journals and called on the experts to learn how to provide their babies with the best diet possible. They found that plant-based diets are associated with a reduced risk of obesity, decreased cholesterol levels, and increased fruit and vegetable intake; in short, not only are they safe for kids, they're pretty freaking awesome.
This is a book about the mystery and the passion, the imagination, religion, and poetry, the philosophy, the intellectual flights—and, above all, the people—that have created the science of astronomy, from Thales of Miletus predicting eclipses in the sixth century B.C. to today’s scientists probing the cosmic significance of the mysterious “black holes” discovered in 1970. With authority and charm, the distinguished Harvard astronomer Charles A. Whitney here re-creates the lives and temperaments of the great astronomers and retraces the ingenious arguments, the feats of observation and deduction, and the leaps of intuition by which they have gradually unveiled a picture of the universe and have brought us to an understanding of our own planet’s place in it. Among them: KEPLER, searching the solar system for visible evidence of the transcendent order he believed in GALILEO, constructing the first telescope and proposing the concept of universal gravitation NEWTON, paragon of logic, paradoxically driven by an unshakable belief in himself as God’s appointed prophet to create a world of mathematical certainty and thus expose the wonder of his Father in Heaven WILLIAM HERSCHEL, the nineteenth-century German who may well be considered the father of modern astronomy, first man to chart the nebulae EDWIN HUBBLE, in the present century, discovering and exploring galaxies beyond our own Finally, Professor Whitney makes clear for the layman the fascinating problems astronomers wrestle with today: the mysterious nature of quasars, strange cosmic bodies discovered in 1963; the unknown forces behind cataclysmic explosions recently glimpsed in other galaxies; the elusive nature of “interstellar dust”; the eternal question of how it all began.
This is an English-language study on the architecture and art of medieval France of the Romanesque and Gothic periods between 1000-1500. In addition to essays on individual monuments there are general discussions of given periods and specific problems such as: why did Gothic come into being? Whitney Stoddard explores the interrelationship between all forms of medieval ecclesiastical art and characterization of the Gothic cathedral, which he believes to have an almost metaphysical basis.
olymerases are the nucleotidyl transferases that are responsible for synthesizing DNA and RNA. They are crucial for essential cellular processes including cellular and viral genome replication, DNA repair and damage tolerance, and transcription. Consistent with their vital roles, polymerases are found in all domains of life. The overall chemistry employed by these enzymes is conserved but there are variations among the different groups of polymerases that confer different substrate specificities and nucleotide incorporation fidelities that allow them to be involved in a wide array of cellular activities. Since polymerases were first isolated more than six decades ago, we have made great progress in understanding how different polymerases have adapted to their specific roles. In this Research Topic we will focus on the enzymatic mechanisms of these enzymes and the relationships between polymerase structure and mechanism, to highlight common themes and unique adaptations.
