Abstract

In the first two months of 2021, the production of COVID-19 vaccines has suffered setbacks delaying the implementation of national inoculation strategies. These delays have revealed the concentration of vaccine manufacture in a small club of producer nations, which in turn has implications for the degree to which cross-border value chains can deter more aggressive forms of Vaccine Nationalism, such as export curbs. This paper documents the existence of this club, taking account of not just the production of final vaccines but also the ingredients of and items needed to manufacture and distribute COVID-19 vaccines. During 2017-19, vaccine producing nations sourced 88 percent of their key vaccine ingredients from other vaccine producing trading partners. Combined with the growing number of mutations of COVID-19 and the realization that this coronavirus is likely to become a permanent endemic global health threat, this finding calls for a rethink of the policy calculus towards ramping up the production and distribution of COVID-19 vaccines, its ingredients, and the various items needed to deliver them. The more approved vaccines that are safely produced, the smaller will be the temptation to succumb to zero-sum Vaccine Nationalism.

Abstract

Social Networks, Drug Injectors' Lives, and HIV/AIDS recognizes HIV as a socially structured disease - its transmission usually requires intimate contact between individuals - and shows how social networks shape high-risk behaviors and the spread of HIV. The authors recount the groundbreaking use of social network methods, ethnographic direct-observation techniques, and in-depth interviews in their study of a drug-using community in Brooklyn, New York. They provide a detailed documentary of the lives of community members. They describe drug-use, the affects of poverty and homelessness, the acquisition of money and drugs, and social relationships within the group. Social Networks, Drug Injectors' Lives, and HIV/AIDS shows that social networks and contexts are of crucial importance in understanding and fighting the AIDS epidemic. These findings should revitalize prevention efforts and reshape social policy.

Abstract

This book is a collection of 13 innovative papers describing the state of the art and the future perspectives in solid-phase extraction covering several analytical fields prior to the use of gas or liquid chromatographic analysis. New sorptive materials are presented including carbon nanohorn suprastructures on paper support, melamine sponge functionalized with urea–formaldehyde co-oligomers, chiral metal–organic frameworks, UiO-66-based metal–organic frameworks, and fabric phase sorptive media for various applications. Solid-phase extraction can be applied in several formats aside from the conventional cartridges or mini-column approach, e.g., online solid-phase extraction, dispersive solid-phase microextraction, and in-syringe micro-solid-phase extraction can be very helpful for analyte pre-concentration and sample clean-up. Polycyclic musks in aqueous samples, 8-Nitroguanine in DNA by chemical derivatization antibacterial diterpenes from the roots of salvia prattii, perfluoroalkyl substances (PFASs) in aater samples by bamboo charcoal-based SPE, parabens in environmental water samples, benzotriazoles as environmental pollutants, organochlorine pesticide residues in various fruit juices and water samples and synthetic peptide purification are among the applications cited in this collection. All these outstanding contributions highlight the necessity of this analytical step, present the advantages and disadvantages of each method and focus on the green analytical chemistry guidelines that have to be fulfilled in current analytical practices.

Abstract

The development of micro- and nanodevices for blood analysis continues to be a growing interdisciplinary subject that demands the careful integration of different research fields. Following the success of the book “Micro/Nano Devices for Blood Analysis”, we invited more authors from the scientific community to participate in and submit their research for a second volume. Researchers from different areas and backgrounds cooperated actively and submitted high-quality research, focusing on the latest advances and challenges in micro- and nanodevices for diagnostics and blood analysis; micro- and nanofluidics; technologies for flow visualization and diagnosis; biochips, organ-on-a-chip and lab-on-a-chip devices; and their applications to research and industry.

Abstract

This work covers all aspects related to the obtainment, production, design, and processing of biopolymers obtained from natural resources. Moreover, it studies characteristics related to the improvement of their performance to increase their potential application at an industrial level, in line with the concept of a global circular economy. Thus, this work firstly classifies biopolymers obtained from natural resources (e.g., biobased building blocks and biopolymers extracted directly from plants and biomass), and then summarizes several cutting-edge research works focused on enhancing the performance of biopolymers from natural resources to extend their application in the industrial sector, and contribute to the transition to more sustainable plastics.

Abstract

Flow analysis is an automatic, precise and fast way to perform analytical tests. Flow instruments are used for clinical and pharmaceutical analyses, quality control of industrial products, monitoring of environmental pollution and many other fields. The book presents the latest methodological, technical and instrumental achievements in flow analysis. It shows new possibilities for the miniaturization and full mechanization of flow systems, together with examples of their interesting application. The proposed solutions contribute to reducing the amount of used reagents and waste, as well as increasing the safety of working with hazardous reagents, resulting in modern devices operating in accordance with the principles of green chemistry. A number of innovative methods of processing and measuring analytical samples have also been described. The book very well reflects the current state of flow analysis and development directions.
