The halogens chlorine (Cl2) and bromine (Br2) are highly reactive oxidizing elements with widespread industrial applications and a history of development and use as chemical weapons. When inhaled, depending on the dose and duration of exposure, they cause acute and chronic injury to both the lungs and systemic organs that may result in the development of chronic changes (such as fibrosis) and death from cardiopulmonary failure. A number of conditions, such as viral infections, coexposure to other toxic gases, and pregnancy increase susceptibility to halogens significantly. Herein we review their danger to public health, their mechanisms of action, and the development of pharmacological agents that when administered post-exposure decrease morbidity and mortality.

While the U.N. Chemical Weapons Convention bans tear gas and other chemical weapons from use in war, their use is still allowed in domestic policing. Public concern about tear gas utilization increases when social justice protesters are subjected to these chemical demonstration control agents. The history of tear gas utilization by law enforcement in the U.S. is rife with corruption and racist intent. Furthermore, the scientific evidence supporting the safety of tear gas is lacking due to both the misinterpretation of public health studies and the paucity of controlled experiments. We find that the current utilization of tear gas is a threat to public health, free speech, and possibly falls outside of the exception for domestic use. We discuss policy alternatives that include alternative crowd control methods, changes to protocols for tear gas deployment and post-use review, increased regulatory oversight, and the possibility of a complete tear gas ban.

On the first program topic concerning urology in the Soviet health care system were reports by Prof. I. V. Kudintsev on the state and history of development of urological care in the Ukrainian SSR. Prof. Voytashevsky made a report on the state and development of minor urology. Prof. P. M. Fronshtein, like the previous speakers, pointed out the insufficient attention to the teaching of urology in the system of public health care.

In the Cold War, “development” was a catchphrase that came to signify progress, modernity, and economic growth. Development aid was closely aligned with the security concerns of the great powers, for whom infrastructure and development projects were ideological tools for conquering hearts and minds around the globe, from Europe and Africa to Asia and Latin America. This book provides a global history of development, drawing on a wealth of archival evidence to offer a panoramic and multifaceted portrait of a Cold War phenomenon that transformed the modern world. Taking readers from the aftermath of the Second World War to the tearing down of the Berlin Wall, the book shows how development projects altered local realities, transnational interactions, and even ideas about development itself. The book shines new light on the international organizations behind these projects—examining their strategies and priorities and assessing the actual results on the ground—and it also gives voice to the recipients of development aid. It shows how the Cold War shaped the global ambitions of development on both sides of the Iron Curtain, and how international organizations promoted an unrealistically harmonious vision of development that did not reflect local and international differences. The book presents a global perspective on Cold War development, demonstrating how its impacts are still being felt today.

Subject. The article addresses the history of development and provides the criticism of existing criteria for aggregate social welfare (on the simple exchange economy (the Edgeworth box) case). Objectives. The purpose is to develop a unique classification of criteria to assess the aggregate social welfare. Methods. The study draws on methods of logical and mathematical analysis. Results. The paper considers strong, strict and weak versions of the Pareto, Kaldor, Hicks, Scitovsky, and Samuelson criteria, introduces the notion of equivalence and constructs orderings by Pareto, Kaldor, Hicks, Scitovsky, and Samuelson. The Pareto and Samuelson's criteria are transitive, however, not complete. The Kaldor, Hicks, Scitovsky citeria are not transitive in the general case. Conclusions. The lack of an ideal social welfare criterion is the consequence of the Arrow’s Impossibility Theorem, and of the group of impossibility theorems in economics. It is necessary to develop new approaches to the assessment of aggregate welfare.
