In Do Good Fences Make Good Neighbors?, defense analyst Brent Sterling examines the historical use of strategic defenses such as walls or fortifications to evaluate their effectiveness and consider their implications for modern security.Sterling studies six famous defenses spanning 2,500 years, representing both democratic and authoritarian regimes: the Long Walls of Athens, Hadrian's Wall in Roman Britain, the Ming Great Wall of China, 606 $aFortification$xHistory 606 $aNational security$xHistory 606 $aSecurity, International 608 $aElectronic books. 615 0$aFortification$xHistory. 615 0$aNational security$xHistory. 615 0$aSecurity, International. 676 $a355/.033 700 $aSterling$b Brent L$0931059 712 02$aGeorgetown University.$bCenter for Peace and Security Studies. 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910458373303321 996 $aDo good fences make good neighbors$92094392 997 $aUNINA LEADER 04581nam 22007215 450 001 9910720073603321 005 20251008153641.0 010 $a9783031277993$b(electronic bk.) 010 $z9783031277986 024 7 $a10.1007/978-3-031-27799-3 035 $a(MiAaPQ)EBC7242910 035 $a(Au-PeEL)EBL7242910 035 $a(DE-He213)978-3-031-27799-3 035 $a(OCoLC)1378933588 035 $a(PPN)269660887 035 $a(CKB)26540722100041 035 $a(EXLCZ)9926540722100041 100 $a20230428d2023 u| 0 101 0 $aeng 135 $aurcnu|||||||| 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 10$aMelanins: Functions, Biotechnological Production, and Applications /$fedited by Guillermo Gosset 205 $a1st ed. 2023. 210 1$aCham :$cSpringer International Publishing :$cImprint: Springer,$d2023. 215 $a1 online resource (150 pages) 311 08$aPrint version: Gosset, Guillermo Melanins: Functions, Biotechnological Production, and Applications Cham : Springer International Publishing AG,c2023 9783031277986 327 $aChapter 1 Melanin synthesis in bacteria: who, how and why -- Chapter 2 The role of melanin in fungal disease -- Chapter 3 Melanosome origins, diversity and functional relevance across animals -- Chapter 4 Biotechnological production of melanins with recombinant microorganisms -- Chapter 5 Extraction, purification, and characterization of microbial melanin pigments -- Chapter 6 Exploiting melanin-metal interactions for emerging technologies -- Chapter 7 Fundamentals and applications of optically active melanin-based materials. 330 $aThis book provides an up-to-date overview of the biological functions of melanins, their biotechnological production, and their industrial applications. The melanins form a group of polymeric pigments found in most organisms. These natural products are generated by the oxidation of phenolic and indolic molecules yielding melanins, which include eumelanin, pheomelanin, pyomelanin, and the allomelanins. These pigments have diverse biological functions, including photoprotection, thermoregulation, antioxidation, virulence, and metal ion sequestration. Melanins have physicochemical properties that have proven useful in the optical, electronic, material, agriculture, cosmetic, pharmaceutical, and medical industries. The chapters in this book provide an in-depth analysis of the current issues and challenges in this field. Topics covered include the properties, biogenesis, and evolution of melanosomes. The book also addresses the synthesis and industrial production of melanins by microorganisms. The metabolic pathways for the synthesis of several types of polymeric pigments in microorganisms and their role in pathogenesis are reviewed. The large-scale production and purification of melanins to provide this product for industrial applications is a formidable challenge. Two chapters present and discuss the state-of-the-art used for the generation of microbial melanin-production strains and the processes for the biotechnological synthesis and purification of these pigments. Melanins are polymers that can interact with metals, a chapter reviews this capacity in the context of technological applications, including electrochemical energy storage and metal recovery. These polymers are materials having favorable characteristics for photonic applications, including UV blocking and broadband absorption. The current advances in the application of these pigments in optically active materials are presented and discussed. 606 $aBiotechnology 606 $aMicrobiology 606 $aBiochemistry 606 $aMetabolism 606 $aCytology 606 $aNatural products 606 $aGenetics 606 $aBiotechnology 606 $aMicrobiology 606 $aMetabolic Pathways 606 $aNatural Products 606 $aGenetics and Genomics 615 0$aBiotechnology. 615 0$aMicrobiology. 615 0$aBiochemistry. 615 0$aMetabolism. 615 0$aCytology. 615 0$aNatural products. 615 0$aGenetics. 615 14$aBiotechnology. 615 24$aMicrobiology. 615 24$aMetabolic Pathways. 615 24$aNatural Products. 615 24$aGenetics and Genomics. 676 $a780 676 $a612.7927 702 $aGosset$b Guillermo 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 912 $a9910720073603321 996 $aMelanins$93419626 997 $aUNINA
