Pradeep L. Menezes, "Self-Lubricating Composites"
English | ISBN: 3662642425 | 2022 | 311 pages | EPUB | 6 MB
In most tribological applications, liquid or grease based lubricants are used to facilitate the relative motion of solid bodies to minimize friction and wear between interacting surfaces. The challenges for liquid lubricants arise in extreme environmental conditions, such as very high or low temperatures, vacuum, radiation, and extreme contact pressure. At these conditions, solid lubricants may be the alternative choice which can help to decrease friction and wear without incorporating liquid lubricants. Challenges with solid lubricants are to maintain a continuous supply of solid lubricants on the contact surfaces to act as lubricous layer between two sliding surfaces. Such a continuous supply is more easily maintained in the case of liquid lubricants when compared to solid lubricants. The most innovative development to ensure a continuous supply of solid lubricant to the contact surface during sliding is to introduce solid lubricant as reinforcement into the matrix of one of the sliding components. Composite materials are engineered or naturally occurring materials which contain two or more distinct constituents with significantly different chemical, physical and mechanical properties. Composites consist of reinforcement and matrix (metal, polymer and ceramics). Among various reinforcements, recent emerging material, solid lubricant, is found to have many favorable attributes such as good lubrication property. Self‐lubrication is the ability of a material to provide lubrication to the contact surface to decrease friction and wear rate in the absence of an external lubricant by transferring embedded solid lubricants in the composite to the interface. Self-lubricating composites (SLCs) are an important category of engineering materials that are increasingly replacing a number of conventional materials in the automotive, aerospace, and marine industries due to superior tribological properties. In SLCs, solid lubricant materials, including carbonous materials, molybdenum disulfide (MoS

Self-Healing Structures, Machines, and Systems by Dryver R. Huston
English | June 29, 2025 | ISBN: 1032488492 | 478 pages | MOBI | 27 Mb
This book describes the behavior, underlying principles and design of self-healing materials, structures, machines, and systems. Self-healing is a ubiquitous phenomenon that appears in many systems ranging from the molecular scale up through to large macroscale systems and in domains ranging from materials such as self-healing polymers, to self-sealing tires, water distribution networks, and information systems, including control systems for damaged aircraft. Self-healing extends performance and endurance in ways that are just not possible otherwise. This book presents a unifying holistic approach to the operation and design of self-healing systems. It acts as a valuable reference for students, researchers, and engineers that are interested in understanding self-healing mechanisms and acquiring techniques to extend the performance and endurance of the structures, machines, and systems that they build, design, and study.

Self-Esteem Research, Theory, and Practice: Toward a Positive Psychology of Self-Esteem, Third Edition By Christopher J. Mruk
2006 | 316 Pages | ISBN: 082610231X | PDF | 2 MB
Dr. Mruk has produced a highly readable new edition of his original work on an often misunderstood psychological construct--self-esteem. Mruk's view that self-esteem is a critically important influence on psychological adjustment and quality of life is now an accepted tenet in personality theory. Lack of self-esteem is frequently a precursor to depression, suicidal behavior, and other personality disorders. Nonetheless, the clinical diagnosis of self-esteem problems has lacked the basis of an overarching theory. Dr. Mruk's comprehensive analysis distills the literature on self-esteem into practical and reliable treatment methods for both clinicians and researchers. The new edition contains updated research and current terms, and addresses the self-esteem "backlash." He concludes with worksheets and detailed guidelines for conducting self-esteem building workshops. Added features include: Major theories of self-esteem Chapter on the new positive psychology 150 new references Dr. Mruk has developed a writing style that is successfully oriented toward both academic and clinical audiences in the areas of counseling, education, nursing, psychology, and social work, thus providing much-needed information for teachers, students, and practicing clinicians in a clear, concise way.

Self, Identity, and Social Institutions By David R. Heise, Neil J. MacKinnon
2010 | 279 Pages | ISBN: 0230621791 | PDF | 2 MB
This book shows how the individual constructs a self from the thousands of colloquial identities provided by a society's culture, and reveals how the individual actualizes and sustains an integrated and stable self while navigating the sometimes treacherous waters of everyday institutional life. MacKinnon and Heise identify a cultural theory of people that is implicit in the semantics of identity-nouns and outline how that theory functions in everyday life and the development of the self; the book identifies major social institutions through network analysis of identity semantics, and it develops a cybernetic model of self-process wherein individuals re-confirm their self-sentiments after participating in disconfirming institutional roles, balancing one inauthenticity with another.

Selected Mathematical Works: Symbolic Logic + The Game of Logic + Feeding the Mind: by Charles Lutwidge Dodgson, alias Lewis Carroll
English | December 19, 2023 | ISBN: 8596547782735 | 679 Pages | EPUB (True) | 1.62 MB
In "Selected Mathematical Works: Symbolic Logic + The Game of Logic + Feeding the Mind," Lewis Carroll, the Victorian polymath renowned for his contributions to literature and mathematics, offers readers a fascinating confluence of logic and playful reasoning. This collection showcases Carroll's pioneering exploration of symbolic logic, employing a whimsical yet precise literary style that characterizes his approach. Through intricate puzzles and engaging games, he invites readers to explore the foundations of mathematical thought while entertaining the mind with the absurdity reminiscent of his fictional works. The nuanced interweaving of logic and creativity situates this collection within both the mathematical discourse of his time and the burgeoning field of logical philosophy. Charles Lutwidge Dodgson, known to the world as Lewis Carroll, was a mathematician and logician whose academic pursuits significantly influenced his literary creations. His background in mathematics was complemented by a strong interest in the mechanics of language and reasoning, leading him to experiment with ideas that bridged these domains. His identity as both a scholar and a storyteller uniquely positioned him to illuminate complex logical principles through engaging narratives and games, making abstract concepts accessible to a broader audience. "Selected Mathematical Works" is an essential read for those interested in the intertwining of logic and literature. Carroll'Äôs ability to simplify complex ideas through playful reasoning not only broadens the reader's understanding of mathematics but also embodies the enduring connection between creativity and analytical thought. This book is a delightful invitation to see logic through the lens of imagination, making it indispensable for both students of mathematics and lovers of literature.

Selbstorganisation durch Selbstdiagnose: Organisationsberatung zwischen Prozess und Struktur (Beraten in der Arbeitswelt)
Deutsch | 19 Jan. 2026 | ASIN: B0GGZG8SXH | 130 Seiten | EPUB (True) | 1.58 MB
In vielen Organisationen stockt trotz klarer Prozesse die Leistung: das Engagement erlahmt, die Verantwortung wandert nach oben, die Steuerung frisst Energie - eine Wirkung bleibt aus. Genau hier setzt Selbstorganisation an: Sie löst das Kontroll-Dilemma, indem Entscheidungen dorthin verlagert werden, wo Wissen und Motivation entstehen - in überschaubare, vertrauensvolle Teams. Das Buch zeigt, wie Gruppen über persönliche Bekanntheit Relevanz füreinander entwickeln, die intrinsische Energie freisetzt und ein belastbares Wir entstehen lässt. Es gilt, die Balance zwischen Verlässlichkeit und Erwartungssicherheit sowie Lern- und Anpassungsfähigkeit zu finden. Zugleich markiert das Konzept Grenzen: Über acht bis zwölf Mitglieder hinaus wird Personenorientierung schwierig - dann wird aus der Gruppe eine Organisation. Der zentrale Impuls: Wer Selbstorganisation will, schafft Bedingungen, in denen eine persönliche Kommunikation gelebt wird - mit Zeit, Verbindlichkeit und gruppendynamischer Kompetenz. Denn Wirkung entsteht durch Beziehung, Verlässlichkeit und Verantwortung. Selbstorganisation ist kein Tool - sie ist Kultur.
