Magnetoelastic Acoustic Emission


Free Download Magnetoelastic Acoustic Emission: Theory and Applications in Ferromagnetic Materials
English | 2024 | ISBN: 9819940311 | 610 Pages | PDF EPUB (True) | 39 MB
The book presents theoretical and experimental studies to establish the relationship between volume jumps of the 90° domain wall in a ferromagnetic material and the magnitude of the half-space surface displacement caused by it. A method of evaluating the influence of the external magnetic field on the stress intensity factor at the tip of the crack-like defects in ferromagnets is discussed. The influence of hydrogen on the generation of magneto-elastic acoustic emission signals of ferromagnets is described. The features of magneto-elastic acoustic emission due to the presence of plastic deformation, structural changes, and volumetric damage in such structural materials are shown.

Ultra-Weak Photon Emission from Biological Systems


Free Download Ultra-Weak Photon Emission from Biological Systems: Endogenous Biophotonics and Intrinsic Bioluminescence
English | 2023 | ISBN: 3031390776 | 511 Pages | PDF EPUB (True) | 161 MB
This book addresses the phenomenon of biological autoluminescence (also known as ultraweak photon emission, UPE, biochemiluminescence, or biophotons) and deals with a very broad spectrum of subjects, ranging from basic observational studies to molecular mechanisms, free-radical processes, physics of electron excitation and photon emission, as well as detection techniques. The chapter topics include UPE in plants, animals, and the human body; microorganisms and subcellular structures; and model systems, illustrating its high prevalence. Several sections of the book provide some backstory, with emphasis on methodology, unresolved questions, and existing controversies. The authors raise and discuss complex, potentially divisive aspects: Are there any reasons to assume the existence of non-chemical interaction in biological systems? Can research results in the field of mitogenetic radiation, delayed luminescence, and oxychemiluminescence of model systems, be correctly interpreted? What does the future hold for this area of research? Altogether, this publication gives the reader a thorough overview of biological autoluminescence (UPE, biophotonics) research, making it ideal for students and researchers who are new to the area as well as those who are specializing in it.

English | 2024 | ISBN: 1071634984 | 454 Pages | PDF (True) | 17 MB
This detailed volume explores key concepts and experimental design related to Positron Emission Tomography (PET) imaging that have revolutionized our understanding of human biology. The first part focuses on recent advances in radiotracer probe development to enable the detection of materials, from large macromolecules to complicated drug-like structures. The next section describes how key physiological and pathophysiological processes can be interrogated and quantifiably measured with this imaging technique. Finally, chapters examine important technological developments in the field that are revolutionizing the way these innovative PET probes are utilized in the clinic. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, as well as tips on troubleshooting and avoiding known pitfalls.

Emission Reduction with an Alternative Diesel Combustion Process


Free Download Emission Reduction with an Alternative Diesel Combustion Process
English | 2023 | ISBN: 3658420936 | 152 Pages | PDF (True) | 4 MB
Marvin SaschaWahl presents the possibilities for optimising diesel engine combustion. In the advanced process of partially premixed diesel combustion, nitrogen oxide and soot emissions can be minimised at the same time. A new feature is the possibility of applying this strategy up to 2000 revolutions and 10 bar indicated mean pressure. In this work, various effective parameters are also compared and correlated with each other. A final comparison with conventional diesel combustion shows the advantages and disadvantages and evaluates them.
