  • By playing a role in the near-annihilation of a species, Theodore Roosevelt, the president of the United States at the turn of the twentieth century, unwittingly laid the groundwork for the most dramatic triumph yet in the use of artificial insemination (AI) to rescue a species from extinction. In the early 1900s, waves of immigrants from Europe settled in the American Midwest. As humans transformed the land, they declared war on a perceived pest: the prairie dog.

  • Normal functioning of reproductive systems of male and female, no doubt is expected of all individuals. But one of the vagaries of nature is aberration of this function. While fertility is an essential ingredient for survival and continuity of species, not all couples are capable of furthering their families. So the problem of infertility finds its place in the recorded history of ancient civilisations of Babylonia, Persia and Greece.1 Goddesses of fertility, fertility rites, and superstitions encompassing the process of birth are mentioned in the history of these civilisations.

  • Dynamical systems theory in mathematical biology and environmental science has attracted much attention from many scientific fields as well as mathematics. For example, “chaos” is one of its typical topics. Recently the preservation of endangered species has become one of the most important issues in biology and environmental science, because of the recent rapid loss of biodiversity in the world. In this respect, permanence or persistence, new concepts in dynamical systems theory, seem important.

  • Mathematical modelling is the process of formulating an abstract model in terms of mathematical language to describe the complex behaviour of a real system. Mathematical models are quantitative models and often expressed in terms of ordinary differential equations and partial differential equations. Mathematical models can also be statistical models, fuzzy logic models and empirical relationships. In fact, any model description using mathematical language can be called a mathematical model.

  • To one who has been an eye-witness of the wonderful achievements of American medical science in the conquest of acute communicable and pestilential diseases in those regions of the earth where they were supposed to be impregnably entrenched, there is the strongest possible appeal in the present rapidly growing movement for the improvement of physical efficiency and the conquest of chronic diseases of the vital organs.

  • This volume is the second of a series, the first of which is "THE SCIENCE OF GETTING RICH." As that book is intended solely for those who want money, so this is for those who want health, and who want a practical guide and handbook, not a philosophical treatise. It is an instructor in the use of the universal Principle of Life, and my effort has been to explain the way in so plain and simple a fashion that the reader, though he may have given no previous study to New Thought or metaphysics, may readily follow it to perfect health. While retaining all essentials,...

  • All living organisms require food for survival, growth, and reproduction. Most broadly, the term food can be taken to include any kind of nutrient needed by animals, plants, and simpler forms of life, on down to bacteria. This would include, for example, the inorganic substances that 5 plants draw from air and water. The processes that circulate these basic nutrients in the environment are called nutrient cycles, and the processes by which organisms make use of nutrients are collectively known as metabolism.
