This book constructs a non-Bloch band theory and studies physics described by non-Hermitian Hamiltonian in terms of the theory proposed here.In non-Hermitian crystals, the author introduces the non-Bloch band theory which produces an energy spectrum in the limit of a large system size. The energy spectrum is then calculated from a generalized Brillouin zone for a complex Bloch wave number. While a generalized Brillouin zone becomes a unit circle on a complex plane in Hermitian systems, it becomes a circle with cusps in non-Hermitian systems. Such unique features of the generalized Brillouin zone realize remarkable phenomena peculiar in non-Hermitian systems. Further the author reveals rich aspects of non-Hermitian physics in terms of the non-Bloch band theory. First, a topological invariant defined by a generalized Brillouin zone implies the appearance of topological edge states. Second, a topological semimetal phase with exceptional points appears, The topological semimetal phase is unique to non-Hermitian systems because it is caused by the deformation of the generalized Brillouin zone by changes of system parameters. Third, the author reveals a certain relationship between the non-Bloch waves and non-Hermitian topology.

Dyes are versatile compounds that have been successfully used in textile printing, rubber, cosmetics, plastic, pharmaceutical, and leather industries to color the products. Dye-using industries, particularly textile or printing industries are responsible for the generation of a great amount of colored wastewater that are polluting and threatening the environment. Many of these dyes are carcinogenic, mutagenic, and teratogenic, as well as harmful to human, aquatic life, and other living things and their elimination from wastewater is highly essential. Various approaches have been implemented in the efforts to mitigate the issue related to textile wastewater, such as adsorption, biological processes, advanced oxidation processes, membrane technology, etc. In this Volume 1, the application of various types of polymers in different wastewater treatment technologies are presented. The synthesis procedure of some polymers, the polymer modification, the effect of operational parameters onpolymer efficiency, the interactions between polymers ¿ dyes, etc are discussed.¿

This book defines Russophobia as the irrational fear of Russia, a key theme in the study of propaganda in the West as Russia has throughout history been assigned a diametrically opposite identity as the ¿Other.¿ Propaganda is the science of convincing an audience without appealing to reason. The West and Russia have been juxtaposed as Western versus Eastern, European versus Asiatic, civilized versus barbaric, modern versus backward, liberal versus autocratic, and even good versus evil. During the Cold War, ideological dividing lines fell naturally by casting the debate as capitalism versus communism, democracy versus totalitarianism, and Christianity versus atheism. After the Cold War, anti-Russian propaganda aims to filter all political questions through the simplistic binary stereotype of democracy versus authoritarianism, which provides little if any heuristic value to understand the complexities of relations. A key feature of propaganda against the inferior ¿Other¿ is both contemptuous derision and panic-stricken fear of the threat to civilization. Russia has therefore throughout history been allowed to play one of two roles¿either an apprentice of Western civilization by accepting the subordinate role as the student and political object, or a threat that must be contained or defeated. While propaganda has the positive effect of promoting unity and mobilizing resources toward rational and strategic objectives, it can also have the negative effect of creating irrational decision-making and obstructing a workable peace.

This book focuses on latest cutting-edge research to address the interaction between risk and innovation management in supply chains. It is predicted that future operations and supply chain management will be more digital. The collection aims on investigating how digital technologies have helped or can help organisations and supply chains being more resilient. The work is a compilation of selected papers from the 2021 International Conference on Operations and Supply Chain Management: Supply Chain Risk & Innovation Management In ¿The Next Normal¿ (ICOSCM 2021). The contents make valuable contributions to academic researchers, practitioners in the industry, and policy makers of respective authorities. Those who lack digital capabilities will find the collection useful in improving their capabilities.

This book scrutinizes the frequently ignored agency of Global South sub-national actors in their interactions with China, using a multidisciplinary approach and eleven case studies. Contributors examine Chinäs presence in the Global South on a country-by-country basis, analyzing how various non-state and sub-state actors are responding to the rise of China and whether they are attracted by the cooperation models that China proposes or deterred by its new assertiveness. Contributions cover diverse and heterogeneous geographies of the Global South, ranging from Papua-New Guinea to Argentina and from Madagascar to the Russian Far East. Examining such diverse cases, contributors focus on two interrelated questions: What is the actual economic, political, and social impact of Chinäs growing presence in the Global South? And, critically, how do the citizens of the Global South understand and interpret Chinäs rise? Taken together, the case studies develop a comprehensive picture of a complex and sometimes problematic process of Chinäs inclusion into the economic, social, and political realities of the Global South.This book identifies and fills the gaps in the existing literature on Chinäs rise by offering a nuanced perspective on Chinäs relations with the countries of the Global South that captures such variables as social context, intersubjective meanings, and identities. By focusing Chinäs relations with the Global South, it also provides an important addition to the literature on international politics of development and Chinäs role in the transformation of the South-South cooperation.

The textile industry is among the most significant polluters of water owing to the existence of various types of pollution streams generated by printing processes and textile dyeing. The book begins by documenting various types of Poly (vinyl alcohol) PVA-derived adsorbents (gels, fibers, films, composite particles), membranes, and photocatalysts in combination with conventional adsorbents, polymers, carbonaceous and metallic materials and their use in elimination of dyes from contaminated water. It follows by discussing different properties of nanocomposite membranes such as hydrogels, xerogels and aerogels used in this purpose. Also, different polymer ¿ based adsorbents such as ceramic adsorbent, clay, hydrogels, starch, cellulose, chitosan, alginates, etc are presented in this book.

As such, the book makes a substantial contribution to the literature and outlines the key challenges in research, policy, and practice for STEM education, from early childhood through to the first school age education. The audience for the book includes college students, teachers of young children, college and university faculty, and professionals from fields other than education who are unified by their commitment to the care and education of young children.

This book explores the petition(¿¿), a political system with Chinese characteristics. It is an important form of political participation for people at the bottom and an effective means of supervising officials at the grassroots level for the higher-level government. Through a half-year fieldwork of the Public Security Bureau, the author found that the operational logic of the petition seems to be different from the past, and it is the change of petition logic that leads to the dilemma that ¿the cost of petitioning is reduced but the road of rights safeguarding is narrowed,¿ or in other words, it's easier to make a petition but harder to succeed for those who are truly wronged. This book based on the grassroots of China's legal system is worth reading for those that are interested in studying police and petition as well as political sociology and organizational sociology.

This book delivers essential skills in ¿spoken¿ professional communications, presenting theoretical and applied frameworks for business talk using English as a lingua franca. Adopting a role-playing approach mimicking various professional settings, it assesses the strength of the well-reasoned argument, the logical links that convince the audience of the coherence of the speaker¿s argument and the necessary linguistics competencies. This book centers on a variety of situations that commonly take place in business organizations (such as relational talk; call center talk; job application talk) and addresses key skills such as conflict resolution and collaborative problem solving through communication, which are key for both students and practitioners. In addition it analyses spoken business discourse data with the four main sources of communicative competence: grammatical competence, discourse competence, sociolinguistic competence and strategic competence in order to highlight how they are used in business speaking practices.
