This book covers basic aspects of different nanoparticles, including type of materials, lipid, polymeric and inorganic structures, synthesis strategies, as well as the main physicochemical characterization techniques. Moreover, this book addresses applications for both treatment and diagnosis of diseases, highlighting in vitro and in vivo findings and clinical evaluation. The chapters highlight the main barriers for drug delivery which can benefit from nanoencapsulation: the topical and oral routes. The main innovations in the field, such as gene therapy and functionalization of nanoparticles with a variety of moieties, including monoclonal antibodies for selective delivery, are discussed and illustrated with examples. Finally, the application of nanoparticles for drug delivery to cancer is reviewed considering toxicology and regulatory aspects.

Artists and the Practice of Agriculture maps out examples of artistic practices that engage with the aesthetics and politics of gathering food, growing edible and medicinal plants, and interacting with non-human collaborators. In the hands of contemporary artists, farming and foraging become forms of visual and material language that convey personal and political meanings. This book provides a critical analysis of artistic practices that model alternative food systems. It presents rich academic insights as well as 16 conversations with practicing artists. The volume addresses pressing issues, such as the interconnectedness of human and other-than-human beings, the weight of industrial agriculture, the legacy of colonialism, and the promise of place-based and embodied pedagogies. Through participatory projects, the artists discussed here reflect on the links between past histories, present challenges, and future solutions for the food sovereignty of local and networked communities. The book is an easy-to-navigate resource for readers interested in food studies, visual and material cultures, contemporary art, ecocriticism, and the environmental humanities.
Hydrogen Technology: Fundamentals and Applications relates theoretical concepts to practical case studies in the field of hydrogen technology with an emphasis on materials and their applications. To implement hydrogen conversion production processes, it is crucial to understand the structural, microstructural, textural, thermal, catalytic, and electrochemical properties of materials. Covering nanomaterials, heterogeneous catalysis, greenhouse gas conversion, reforming reactions for hydrogen production, valorization of hydrogen energy, biomass valorization, the hydrogen economy, and its technical feasibility, this book addresses how bio/hydrogen technology can be used to solve environmental p...
The number of hours individuals spend in front of screens, such as smartphones, televisions, computers, and tablets, is enormous in today’s society because screen time plays a very important role in work contexts and an even more significant role in social interaction and cultural consumption. This almost compulsive relationship with screens is more evident in children and young people and can have a lasting impact on how a society approaches screen time. Managing Screen Time in an Online Society is a collection of innovative research on how screen time seduces the person to stay in the online interaction leaving her/him in a state of alienation from her/his face-to-face context. While highlighting the methods and applications of time management in the context of screen time, especially during leisure, social interaction, and cultural consumption, this book covers topics including media consumption, psychology, and social networks. This book is ideal for researchers, students, and professionals seeking emerging information on the relationship between online interaction and personal relationships.
This book explores the most effective or promising catalytic processes for the conversion of biobased components into high added value products, as platform chemicals and intermediates.
The state of São Paulo, Brazil, is one of the most densely populated and developed areas in South America. Such development is evident both in terms of industrialization and urbanization, as well as in agriculture, which is heavily based on sugar cane, Eucalyptus plantations and livestock. This intense land use has resulted in great alteration of the original land cover and fragmentation of natural ecosystems. For these reasons, it is almost a paradox that jaguar, a species that requires large areas of pristine forest to exist, is still found in some parts of the state of São Paulo. It is possible that wild animals could leave in coexistence with intense land use, or is it the case that su...
Regulations affecting 10 areas of everyday business are measured: starting a business, dealing with licenses, employing workers, registering property, getting credit, protecting investors, paying taxes, trading across borders, enforcing contracts, and closing a business. 'Doing Business 2008' updates all 10 sets of indicators, ranks countries on their overall ease of doing business, and analyzes reforms to business regulation - identifying which countries are improving their business environment the most and which ones slipped. The indicators are used to analyze economic outcomes and identify what reforms have worked, where and why. 'Doing Business 2008' focuses on how complex business regulations dampen investment, growth and job creation in all businesses, and especially opportunities for women entrepreneurs.
This book is an abridgement and translation of Guillermo Lora's five-volume history. It deals with the strengthening and radicalisation of Bolivia's organised labour movement, which culminated in the drastic revolutionary changes of the 1950s. The first half offers a reinterpretation of Bolivian history in the century preceding the revolution, viewed from the perspective of the working class. The second half discusses in more detail the major political events and doctrinal issues of a period in which the author, as secretary of the Trotskyist Partido Obrero Revolucionario, himself frequently played an active part. Despite the radical upheaval that occurred in the fifties and the mobilisation of broad sectors of the population around such radical objectives as direct property seizures, union-nominated ministers and union, military and worker control, the labour movement was unable to maintain its conquests in the 1960s. The concluding chapters describe the period of renewed military repression and the continuing efforts of the labour movement to resist.
