Coups and dictatorships have characterized the Central African Republic since its independence in 1960, but the current crisis is far more dangerous than what has come before. Consider this, in a country of approximately 5 million people, roughly 1.1 million citizens face serious food insecurity. Some 460,000 CAR nationals are displaced, including 64,000 who have fled to neighboring countries as refugees and nearly 400,000 who are internally displaced. This is because there has been a complete breakdown of law and order in the country following the ouster of President Francois Bozize in March of 2013.Crisis in the Central African RepublicPolitical violenceCentral African RepublicPolitics and governmentUnited StatesForeign relationsCentral African RepublicPolitical violence.303.6Arieff Alexis1242603Husted Tomas F.Library of Congress.Congressional Research Service,NjHacINjHaclBOOK9910708253703321Crisis in the Central African Republic3542417UNINA04738nam 22007335 450 991100736770332120250601130233.03-031-88827-810.1007/978-3-031-88827-4(CKB)39160844100041(MiAaPQ)EBC32142870(Au-PeEL)EBL32142870(DE-He213)978-3-031-88827-4(EXLCZ)993916084410004120250601d2025 u| 0engur|||||||||||txtrdacontentcrdamediacrrdacarrierIdentification of Special-Purpose Structures by Their Fragments Based on Scanning Electron Microscopy /by Viacheslav L.

Sperkach1st ed. 2025.Cham :Springer Nature Switzerland :Imprint: Springer,2025.1 online resource (380 pages)Advanced Structured Materials,1869-8441 ;2333-031-88826-X Analysis of Available Methods of Investigating Metallic and Composite Materials, and the Choice of Optimal Research Methods -- Using Scanning Electron Microscopy for Studying Metal Fragments of Special-Purpose Structures -- Application of Scanning Electron Microscopy for the Study of Fragments of Special-Purpose Structures Made of Composite Materials -- Application of Scanning Electron Microscopy for the Study of Fragments of Radio-Absorbing Composite Materials and Coatings -- Using Scanning Electron Microscopy to Identify Special-Purpose Structures by Their Fragments.This book contains previously classified information on the physical and chemical characteristics of metallic and composite materials used in the production of elements of special-purpose structures, and reveals the set of techniques and tools through which this information was obtained. It sets the foundations for the methodology of systematic automated identification of the special-purpose structures by their fragments. The main topics are theoretical foundations and practical results of scanning electron microscopy in determining chemical composition, structure, surface topography and frequency characteristics (reflection and absorption coefficients of electromagnetic waves) of fragments of the structures made of both metal alloys and composite materials. Applied aspects such as the parameters of electromagnetic radiation recommended for effective identification of special-purpose structures made of composite radiation absorbent materials and coatings; development of a scientifically based system for automated identification of the structures by their fragments. The book is aimed at solving the problem to prevent uncontrolled or "gray" transfer of special-purpose products, technologies and materials of military or dual use by forming a scientifically based automatic identification system (by class and country of origin) of special-purpose products by their fragments, using scanning electron microscopy to determine their chemical composition, structure, surface topography, and frequency characteristics. The book is useful to a wide range of specialists in the field of materials science, as well as specialists in the defense sector of industry.Advanced Structured Materials,1869-8441 ;233X-ray spectroscopyMaterialsMicroscopyMetalsMaterialsAnalysisComposite materialsX-Ray SpectroscopyMicroscopyMetals and AlloysMaterials Characterization TechniqueCompositesX-ray spectroscopy.MaterialsMicroscopy.Metals.MaterialsAnalysis.Composite materials.X-Ray Spectroscopy.Microscopy.Metals and Alloys.Materials Characterization Technique.Composites.543.62Bogdanov Viacheslav L1220081Grigorenko Alexander Ya927860Chepkov Ihor B1826781Odnoralov Ihor V1826782Kuchynskyi Andrii V1826783Kremenytskyi Valerii V1826784Sperkach Svitlana O1826785MiAaPQMiAaPQMiAaPQBOOK9911007367703321Identification of Special-Purpose Structures by Their Fragments Based on Scanning Electron Microscopy4394782UNINA
