Available in PDF, EPUB and Kindle. Book excerpt: Mitosis in sea urchin eggs was retarded following their exposure to magnetic fields higher than 70,000 gauss which had gradients greater than 4200 gauss/centimeter. The degree of retardation was correlated simultaneously to both the field strength and the field gradient. Division delay in fields ranging from 100,000 to a maximum of 120,000 gauss was independent of the gradient. Differences in division delay were found which may be a reflection of the differential migration of oxygen and nitrogen due to their para- and diamagnetic properties. An hypothesis is given concerning the biochemical processes affected by magnetic fields. (Author).

This book was released on 2018-10-03 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioengineering and Biophysical Aspects of Electromagnetic Fields primarily contains discussions on the physics, engineering, and chemical aspects of electromagnetic (EM) fields at both the molecular level and larger scales, and investigates their interactions with biological systems. The first volume of the bestselling and newly updated Handbook of Biological Effects of Electromagnetic Fields, Third Edition, this book adds material describing recent theoretical developments, as well as new data on material properties and interactions with weak and strong static magnetic fields. Newly separated and expanded chapters describe the external and internal electromagnetic environments of organisms and recent developments in the use of RF fields for imaging. Bioengineering and Biophysical Aspects of Electromagnetic Fields provides an accessible overview of the current understanding on the scientific underpinnings of these interactions, as well as a partial introduction to experiments on the interactions themselves.

Download or read book Space Radiation Biology and Related Topics written by Cornelius A. Tobias and published by Elsevier. This book was released on 2013-10-22 with total page 665 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space Radiation Biology and Related Topics provides information pertinent to the fundamental aspects of space radiation biology. This book discusses space radiation hazards as well as the importance of natural radiations in the processes of biogenesis. Organized into 12 chapters, this book begins with an overview of the fundamental aspects of radiobiology. This text then discusses the theoretical treatments of the chronic radiation response and the applicability of some of its features in extended manned space missions. Other chapters review the literature on models for recovery from radiation damage to some cellular systems. This book discusses as well the effects of radiations on mammals, with emphasis on those effects pertinent to the space-flight situation. The final chapter deals with the safety of nuclear power in space and explains the three types of nuclear devices designed for power production in space. This book is a valuable resource for radiologists, radiobiologists, and radiotherapists.
