Investigations in General Biology presents an overview of studies in general biology, including behavior, biological models, cell activities, organization of plants and animals, population genetics, and evolution.
The opening chapters deal with the significance of accurate observations of systematic ordering of biological events in plants and animals. The use of laboratory tools for biological analysis and the application of such tools in biological diffusion process are also considered. This book describes the use of model to investigate cellular phenomenon and an application of a valid model of cell membrane function using microscope. The responses in solutions of different concentrations are recorded. Considerable chapters discuss refined experimental approach to testing a biological hypothesis, with emphasis on the idea of using a control. The control indicates the amount of response that occurs due to variables not anticipated.
Furthermore, this book discusses the organization of the flowering plant, including those organs involved in maintenance as well as animal organization, particularly, in crayfish and frog. It presents the proper statistical procedures that can be used by geneticist to determine probability genetic ratio. It explains gene frequencies of characters in human populations and consequences of nonrandom reproduction and subsequent departure from Hardy-Weinberg equilibrium. Finally, the concluding chapters deal with physiological attributes and classification of animal and plant population.
General biology students and instructors will greatly benefit from this book.

Ion Beam Handbook for Material Analysis emerged from the U.S.-Italy Seminar on Ion Beam Analysis of Near Surface Regions held at the Baia-Verde Hotel, Catania, June 17-20, 1974. The seminar was sponsored by the National Science Foundation and the Consiglio Nazionale delle Ricerche under the United States-Italy Cooperative Science Program. The book provides a useful collection of tables, graphs, and formulas for those involved in ion beam analysis. These tables, graphs, and formulas are divided into five chapters that cover the following topics: energy loss and energy straggling; backscattering spectrometry; channeling; applications of ion-induced nuclear reactions; and the use of ion-induced X-ray yields.

This conference consisted of 15 oral sessions, including three plenary papers covering areas of general interest, 22 specialist invited papers and 51 contributed presentations as well as three poster sessions. There were several scientific highlights covering a diverse spectrum of materials and ion beam processing methods. These included a wide range of conventional and novel applications such as: optical displays and opto-electronics, motor vehicle and tooling parts, coatings tailored for desired properties, studies of fundamental defect properties, the production of novel (often buried) compounds, and treating biomedical materials. The study of nanocrystals produced by ion implantation in a range of host matrices, particularly for opto-electronics applications, was one especially new and exciting development. Despite several decades of study, major progress was reported at the conference in understanding defect evolution in semiconductors and the role of defects in transient impurity diffusion. The use of implantation to tune or isolate optical devices and in forming optically active centres and waveguides in semiconductors, polymers and oxide ceramics was a major focus of several presentations at the conference. The formation of hard coatings by ion assisted deposition or direct implantation was also an area which showed much recent progress. Ion beam techniques had also developed apace, particularly those based on plasma immersion ion implantation or alternative techniques for large area surface treatment. Finally, the use of ion beams for the direct treatment of cancerous tissue was a particularly novel and interesting application of ion beams.

Containing the proceedings of three symposia in the E-MRS series this book is divided into two parts. Part one is concerned with ion beam processing, a particularly powerful and versatile technology which can be used both to synthesise and modify materials, including metals, semiconductors, ceramics and dielectrics, with great precision and excellent control. Furthermore it also deals with the correlated effects in atomic and cluster ion bombardment and implantation.

Part two deals with the deposition techniques, characterization and applications of advanced ceramic, metallic and polymeric coatings or thin films for surface protection against corrosion, erosion, abrasion, diffusion and for lubrication of contracting surfaces in relative motion.

Ion Beam Treatment of Polymers, Second Edition presents the results of polymer investigations and technique development in the field of polymer modification by high-energy ion beams. It shows how to use ion beam equipment in the polymer industry, as well as how to use it to produce new polymer materials. The authors, scientists and researchers active in the field, provide analysis and data from their work, and give an overview of related work by others. The authors focus on wetting, adhesion, hardness, chemical activity, environmental stability, biocompatibility, new synthesis methods, and space flight construction.

The technologies of material modification by a beam of high energy ions have wide applications in different fields, from microelectronics to medicine. Historically, ion beam treatment of polymers had fewer applications due to high costs of ion beam equipment and low costs of polymer materials. The modern development of new pulse sources with a high current density and wide ion beams increase the effectiveness of ion beam technology for polymers.

• Collates data from many scientists working in polymer chemistry, physics of ion beam implantation, and in development and production of ion beam equipment
• Covers industrial and scientific applications of ion beam implanted polymers
• Integrates physical and chemical aspects of the processes in polymers treated by ion beams

The use of ion beams for materials analysis involves many different ion-atom interaction processes which previously have largely been considered in separate reviews and texts. A list of books and conference proceedings is given in Table 2. This book is divided into three parts, the first which treats all ion beam techniques and their applications in such diverse fields as materials science, thin film and semiconductor technology, surface science, geology, biology, medicine, environmental science, archaeology and so on.
