Vaccines, Medicines and COVID-19: How Can WHO Be Given a Stronger Voice? (SpringerBriefs in Public Health)

by Germán Velásquez

This open access book is a collection of research papers on COVID-19 by Germán Velásquez from 2020 and early 2021 that help to answer the question: How can an agency like the World Health Organization (WHO) be given a stronger voice to exercise authority and leadership? The considerable health, economic and social challenges that the world faced at the beginning of 2020 with COVID-19 continued and worsened in many parts of the world in the second-half of 2020 and into 2021. Many of these countries and nations wanted to explore COVID-19 on their own, sometimes without listening to the main international health bodies such as WHO, an agency of the United Nations system with long-standing experience and vast knowledge at the global level and of which all countries in the world are members. In this single volume, the chapters present the progress of thinking and debate — particularly in relation to drugs and vaccines — that would enable a response to the COVID-19 pandemic or to subsequent crises that may arise. Among the topics covered:COVID-19 Vaccines: Between Ethics, Health and EconomicsMedicines and Intellectual Property: 10 Years of the WHO Global StrategyRe-thinking Global and Local Manufacturing of Medical Products After COVID-19Rethinking R&D for Pharmaceutical Products After the Novel Coronavirus COVID-19 ShockIntellectual Property and Access to Medicines and VaccinesThe World Health Organization Reforms in the Time of COVID-19Vaccines, Medicines and COVID-19: How Can WHO Be Given a Stronger Voice? is essential reading for negotiators from the 194 member countries of the World Health Organization (WHO); World Trade Organization (WTO) and World Intellectual Property Organization (WIPO) staff participating in these negotiations; academics and students of public health, medicine, health sciences, law, sociology and political science; and intergovernmental organizations and non-governmental organizations that follow the issue of access to treatments and vaccines for COVID-19.

Vacuum Bubbling: Techniques and Applications

by Yong Du Jun

Vacuum Bubbling introduces the background and applications for generating bubbles under a vacuum condition, accomplished through depressurization without the need to heat water. It presents the advantage of utilizing vapor bubble in deaeration applications because the diffusion for degassing happens between the water body and micro vapor bubbles without the need of membrane or packing.Instead of relying on massive heating, vacuum bubbling focuses on depressurization down to the level of saturated vapor pressure or below to secure vapor bubbles with virtually zero dissolved non-condensable gases, including oxygen. The book considers prospective applications, such as extracting high-oxygen-content air from water for underwater breathing, pretreatment of aircraft fuel before being pumped into a fuel tank system, and probable desalination applications through massive bubbling combined with low-grade renewable energy.The book is intended for researchers in thermal fluids, heat and mass transfer, process engineering, and water treatment fields and industry professionals working in power generation, plant and process engineering, transportation, and energy.

Vagina Obscura: An Anatomical Voyage

by Rachel E. Gross

A myth-busting voyage into the female body. A camera obscura reflects the world back but dimmer and inverted. Similarly, science has long viewed woman through a warped lens, one focused narrowly on her capacity for reproduction. As a result, there exists a vast knowledge gap when it comes to what we know about half of the bodies on the planet. That is finally changing. Today, a new generation of researchers is turning its gaze to the organs traditionally bound up in baby-making—the uterus, ovaries, and vagina—and illuminating them as part of a dynamic, resilient, and ever-changing whole. Welcome to Vagina Obscura, an odyssey into a woman’s body from a fresh perspective, ushering in a whole new cast of characters. In Boston, a pair of biologists are growing artificial ovaries to counter the cascading health effects of menopause. In Melbourne, a urologist remaps the clitoris to fill in crucial gaps in female sexual anatomy. Given unparalleled access to labs and the latest research, journalist Rachel E. Gross takes readers on a scientific journey to the center of a wonderous world where the uterus regrows itself, ovaries pump out fresh eggs, and the clitoris pulses beneath the surface like a shimmering pyramid of nerves. This paradigm shift is made possible by the growing understanding that sex and gender are not binary; we all share the same universal body plan and origin in the womb. That’s why insights into the vaginal microbiome, ovarian stem cells, and the biology of menstruation don’t mean only a better understanding of female bodies, but a better understanding of male, non-binary, transgender, and intersex bodies—in other words, all bodies. By turns funny, lyrical, incisive, and shocking, Vagina Obscura is a powerful testament to how the landscape of human knowledge can be rewritten to better serve everyone.

Validation and Reconstruction of Remote Sensing Land Surface Temperature Products

by Wei Zhou Lei Fan Wenping Yu Yuechen Li Xujun Han Mingguo Ma Weiyu Shi

This book focuses on validation and reconstruction work on the land surface temperature (LST) products retrieved by thermal infrared remote sensing. The LST is a key parameter in the energy-water balance process and has been widely used in research on the global climate change, water cycle, vegetation growing, and drought detection. Remote sensing retrieving LST is the most important source for regional and even global application. However, there are several factors that limited their widespread use: (1) the thermal infrared remote sensing is easily influenced by clouds; therefore, there are lots of pixel with invalid LST; (2) LST products have not been sufficiently validated in global scale. This book arms to overcome above defects and guide the readers to estimate the LST of cloudy pixel and implement the general validation on the remote sensing LST. Furthermore, it helps to understand the scale mismatch between different observation and land surface heterogeneity. The book covers ground-based observation, validation and reconstruction theories, scale mismatch analysis, heterogeneity and representativeness evaluation for observations, and application cases. It is an essential reference to the quantitative retrieval of thermal infrared remote sensing technologies.

Valorisation of Agro-industrial Residues – Volume I: Biological Approaches (Applied Environmental Science and Engineering for a Sustainable Future)

by Zainul Akmar Zakaria Ramaraj Boopathy Julian Rafael Dib

Agriculture and industry are the two most important economic sectors for various countries around the globe, providing millions of jobs as well as being the main source of income for these countries. Nevertheless, with the increasing demand for agricultural and industrial produce, huge amounts of waste are also being produced. Without proper management, this waste (both liquid and solid) poses a serious threat to overall environmental quality, mainly due to its toxicity and slow degradation processes. Current approaches are effective but would normally require huge capital investments, are labour intensive and generate potential hazardous by-products. As such, there is a need for alternative approaches that are cheaper, easier-to-handle and have a minimum potential impact on environmental quality. This book presents up-to-date approaches using biological techniques to manage the abundance of waste generated from agricultural and industrial activities. It discusses techniques such as bioconversion, biodegradation, biotransformation, and biomonitoring as well as the utilization of these wastes. A number of chapters also include individual case studies to enhance readers’ understanding of the topics. This comprehensive book is a useful resource for anyone involved in agricultural and industrial waste management, green chemistry or biotechnology. It is also recommended as a reference work for graduate students and all agriculture and biotechnology libraries.
