The book discusses the three main ways chemotherapeutic agents act on cells: altering surface properties, inhibiting essential enzymes, and competing with essential metabolic processes. The authors aim to focus on drug mechanisms rather than chemical variations. However, the book lacks clinical or experimental data, and its title might be more appropriately "The Biochemical Basis of Chemotherapy." The second edition of "Theoretical Acoustics" by Philip M. Morse is more than 100 pages longer than the first edition. It includes new material, especially on transient phenomena using operational calculus. The book provides a systematic exposition of methods for solving acoustical problems, with emphasis on characteristic functions for normal modes of vibration. It covers vibrations of strings, bars, membranes, and plates, and sound wave analysis in air, including acoustic impedance, radiation, scattering, and absorption. The book is suitable for physics and communications engineering students, and research workers in acoustics will find the last chapters particularly useful. "Feeding the Human Family" by F. Le Gros Clark discusses the global food production and distribution. It argues that everyone should have access to a diet that provides optimal nutrition, regardless of race, creed, or color. The book combines science with humanity, addressing both the scientific and ethical aspects of food production. It covers individual, regional, and national dietary patterns, as well as world markets and agricultural practices. The author emphasizes the importance of agriculture as an essential industry. The book is written clearly and accurately, with a balanced approach to the subject, and it highlights the need for nutritionists to engage in political and economic discussions.The book discusses the three main ways chemotherapeutic agents act on cells: altering surface properties, inhibiting essential enzymes, and competing with essential metabolic processes.
