Cuban Studies 39 includes essays on: the recent transformation of the Cuban film animation industry; the influence of the liberal agenda of Justo Rufino Barrios on Jose Mart; a profile of the music of the Special Period and its social commentary; an in-depth examination of the contents, important themes, and enormous research potential of the Miscelnea de Expedientes collection at the Cuban National Archive; and a realistic assessment on the political future of Cuba.
This book explores the most pertinent aspects and advancements in sonochemistry, dedicating nine chapters to fundamentals, synthesis methods, and applications. Covering ultrasound as the primary energy source, the initial chapters cover the interaction of ultrasound waves with matter and its diverse applications across various fields. The text further delves into the synthesis of nanomaterials and nanocomposites under varying reaction conditions. Finally, the book examines specific topics, including the application of sonochemistry in wastewater treatment, catalysts, sensors, meat processing, and food packaging. These insights indicate that sonochemistry is an emerging science with promising applications extending beyond the confines of the laboratory.

When other nations are forced to rethink their agricultural and food security strategies in light of the post-peak oil debate, they only have one living example to draw from: that of Cuba in the 1990s. Based on the first and - up till now - only systematic and empirical study to come out of Cuba on this topic, this book examines how the nation successfully headed off its own food crisis after the dissolution of the Soviet Bloc in the early 1990s. The author identifies the policies and practices required for such an achievement under conditions of petroleum-scarcity and in doing so, challenges the mainstream globalized and privatized food systems and food security strategies being driven through in both industrialized and more vulnerable developing regions. Paradoxically, the book dispels the myth that Cuba turned to organic farming nationwide, a myth founded on the success of Cuba's urban organic production systems which visitors to the country are most commonly exposed to. In rural regions, where the author had unique access, industrialized high-input and integrated agriculture is aspired to for the majority of domestic production, despite the ongoing fluctuations in availability of agrochemicals and fuel. By identifying the challenges faced by Cuban institutions and individuals in de-industrializing their food and farming systems, this book provides crucial learning material for the current fledgling attempts at developing energy descent plans and at mainstreaming more organic food systems in industrialized nations. It also informs international policy on sustainable agriculture and food security for less-industrialized countries.

The entire range of the developmental processes in plants is regulated by the shift in the hormonal concentration, tissue sensitivity and their interaction with the factors operating around the plants. Out of the recognized hormones, attention has largely been focused on five (Auxins, Gibberellins, Cytokinin, Abscisic acid and Ethylene). However, in this book, the information about the most recent group of phytohormones (Brassinosteroids) has been compiled by us. It is a class of over 40 polyhydroxylated sterol derivatives, ubiquitously distributed throughout the plant kingdom. A large portion of these steroids is restricted to the reproductive organs (pollens and immature seeds). Moreover, their strong growth-inducing capacity, recognized as early as prior to their identification in 1979, tempted the scientists to visualize the practical importance of this group of phytohormones. The brassin solution, from rape pollen, was used in a collaborative project by the scientists of Brazil and U. S. A. in a p- sowing seed treatment to augment the yield. This was followed by large-scale scientific programmes in U. S. , Japan, China, Germany and erstwhile U. S. S. R. , after the isolation of the brassinosteroids. This approach suits best in today’s context where plants are targeted only as producers and hormones are employed to get desired results. Chapter 1 of this book (which embodies a total of 10 chapters), gives a comprehensive survey of the hitherto known brassinosteroids, isolated from lower and higher plants.
This contributed volume compiles the latest improvements in the field of biotechnology. It focuses on topics that comprises industrial, environment, agricultural and medical related issues to technology and biological studies and exhibits the correlation between the biological world and the dependence of humans on it. The book is organized into five parts covering the role of biotechnology in industrial products, environmental remediation, agriculture and pharmacological agents. Ranging from micro-scale studies to macro, it covers a huge domain of agricultural biotechnology and focuses on important commercial crops (e.g. cacao and coffee), arbuscular mycorrhizal fungi, flow and distribution of phosphorus in agricultural soils in the Latin American region. Overall, the book portrays the importance of modern biotechnology and its role in solving the problems in modern day life. The book is a ready reference for practicing students, researchers of environmental engineering, chemical engineering, agricultural engineering, and other allied fields likewise.
To prevent bacterial adherence, invasion and infection, antimicrobials such as antibiotics are being used and vastly researched nowdays. Several factors such as natural selection, mutations in genes, the presence of efflux pumps, impermeability of the cell wall, structural changes in enzymes and receptors, biofilm formation, and quorum sensing cause microorganisms to develop resistance against antimicrobials. Isolates that synthesize extended spectrum-β-lactamases (ESBL), induced β-lactamases (IBL), carbapenamases, metallo-β-lactamases (MBLs), and New Delhi metallo-β-lactamases (NDM) have emerged. Determining virulence factors such as biofilms and the level of antimicrobial activities of antimicrobial agents alone and in combination with appropriate doses against microorganisms is very important for the diagnosis, inhibition, and prevention of microbial infection. The goal of this book is to provide information on all these topics.
