Available in PDF, EPUB and Kindle. Book excerpt: The depth profiles of intentional or intrinsic constituents of a sample provide valuable information for the characterization of materials. For example, the subtle differences in spatial distribution and composition of many chemical species in the near surface region and across interfacial boundaries can significantly alter the electronic and optical properties of materials. A number of analytical techniques for depth profiling have been developed during the last two decades. neutron Depth Profiling (NDP) is one of the leading analytical techniques. The NDP is a nondestructive near surface technique that utilizes thermal/cold neutron beam to measure the concentration of specific light elements versus their depth in materials. The depth is obtained from the energy loss of protons, alphas or recoil atoms in substrate materials. Since the charged particle energy determination using surface barrier detector is used for NDP, the depth resolution is highly dependent on the detectors an d detection instruments. The depth resolutions of a few tens of nm are achieved with available NDP facilities in the world. However, the performance of NDP needs to be improved in order to obtain a few A depth resolutions.

Download or read book Sterile Insect Technique written by Victor A. Dyck and published by CRC Press. This book was released on 2021-01-06 with total page 1493 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sterile insect technique (SIT) is an environment-friendly method of pest control that integrates well into area-wide integrated pest management (AW-IPM) programmes. This book takes a generic, thematic, comprehensive, and global approach in describing the principles and practice of the SIT. The strengths and weaknesses, and successes and failures, of the SIT are evaluated openly and fairly from a scientific perspective. The SIT is applicable to some major pests of plant-, animal-, and human-health importance, and criteria are provided to guide in the selection of pests appropriate for the SIT. In the second edition, all aspects of the SIT have been updated and the content considerably expanded. A great variety of subjects is covered, from the history of the SIT to improved prospects for its future application. The major chapters discuss the principles and technical components of applying sterile insects. The four main strategic options in using the SIT — suppression, containment, prevention, and eradication — with examples of each option are described in detail. Other chapters deal with supportive technologies, economic, environmental, and management considerations, and the socio-economic impact of AW-IPM programmes that integrate the SIT. In addition, this second edition includes six new chapters covering the latest developments in the technology: managing pathogens in insect mass-rearing, using symbionts and modern molecular technologies in support of the SIT, applying post-factory nutritional, hormonal, and semiochemical treatments, applying the SIT to eradicate outbreaks of invasive pests, and using the SIT against mosquito vectors of disease. This book will be useful reading for students in animal-, human-, and plant-health courses. The in-depth reviews of all aspects of the SIT and its integration into AW-IPM programmes, complete with extensive lists of scientific references, will be of great value to researchers, teachers, animal-, human-, and plant-health practitioners, and policy makers.

This book was released on 2011-06-28 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary focus of this thesis is to theoretically describe nanokelvin experiments in cold atomic gases, which offer the potential to revolutionize our understanding of strongly correlated many-body systems. The thesis attacks major challenges of the field: it proposes and analyzes experimental protocols to create new and interesting states of matter and introduces theoretical techniques to describe probes of these states. The phenomena considered include the fractional quantum Hall effect, spectroscopy of strongly correlated states, and quantum criticality, among others. The thesis also clarifies experiments on disordered quantum solids, which display a variety of exotic phenomena and are candidates to exhibit so-called "supersolidity." It collects experimental results and constrains their interpretation through theoretical considerations. This Doctoral Thesis has been accepted by Cornell University, Ithaca, USA.
Download or read book X Ray and Neutron Dynamical Diffraction written by André Authier and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume collects the proceedings of the 23rd International Course of Crystallography, entitled "X-ray and Neutron Dynamical Diffraction, Theory and Applications," which took place in the fascinating setting of Erice in Sicily, Italy. It was run as a NATO Advanced Studies Institute with A. Authier (France) and S. Lagomarsino (Italy) as codirectors, and L. Riva di Sanseverino and P. Spadon (Italy) as local organizers, R. Colella (USA) and B. K. Tanner (UK) being the two other members of the organizing committee. It was attended by about one hundred participants from twenty four different countries. Two basic theories may be used to describe the diffraction of radiation by crystalline matter. The first one, the so-called geometrical, or kinematical theory, is approximate and is applicable to small, highly imperfect crystals. It is used for the determination of crystal structures and describes the diffraction of powders and polycrystalline materials. The other one, the so-called dynamical theory, is applicable to perfect or nearly perfect crystals. For that reason, dynamical diffraction of X-rays and neutrons constitutes the theoretical basis of a great variety of applications such as: • the techniques used for the characterization of nearly perfect high technology materials, semiconductors, piezoelectric, electrooptic, ferroelectric, magnetic crystals, • the X-ray optical devices used in all modem applications of Synchrotron Radiation (EXAFS, High Resolution X-ray Diffractometry, magnetic and nuclear resonant scattering, topography, etc. ), and • X-ray and neutron interferometry.

Download or read book Conventional Deterrence written by John J. Mearsheimer and published by Cornell University Press. This book was released on 1985-08-21 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional Deterrence is a book about the origins of war. Why do nations faced with the prospect of large-scale conventional war opt for or against an offensive strategy? John J. Mearsheimer examines a number of crises that led to major conventional wars to explain why deterrence failed. He focuses first on Allied and German decision making in the years 1939–1940, analyzing why the Allies did not strike first against Germany after declaring war and, conversely, why the Germans did attack the West. Turning to the Middle East, he examines the differences in Israeli and Egyptian strategic doctrines prior to the start of the major conventional conflicts in that region. Mearsheimer then critically assays the relative strengths and weaknesses of NATO and the Warsaw Pact to determine the prospects for conventional deterrence in any future crisis. He is also concerned with examining such relatively technical issues as the impact of precision-guided munitions (PGM) on conventional deterrence and the debate over maneuver versus attrition warfare.Mearsheimer pays considerable attention to questions of military strategy and tactics. Challenging the claim that conventional detrrence is largely a function of the numerical balance of forces, he also takes issue with the school of thought that ascribes deterrence failures to the dominance of "offensive" weaponry. In addition to examining the military consideration underlying deterrence, he also analyzes the interaction between those military factors and the broader political considerations that move a nation to war.

Download or read book The Paths of Heaven The Evolution of Airpower Theory written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Airpower is not widely understood. Even though it has come to play an increasingly important role in both peace and war, the basic concepts that define and govern airpower remain obscure to many people, even to professional military officers. This fact is largely due to fundamental differences of opinion as to whether or not the aircraft has altered the strategies of war or merely its tactics. If the former, then one can see airpower as a revolutionary leap along the continuum of war; but if the latter, then airpower is simply another weapon that joins the arsenal along with the rifle, machine gun, tank, submarine, and radio. This book implicitly assumes that airpower has brought about a revolution in war. It has altered virtually all aspects of war: how it is fought, by whom, against whom, and with what weapons. Flowing from those factors have been changes in training, organization, administration, command and control, and doctrine. War has been fundamentally transformed by the advent of the airplane.
