Våben og udstyr

This is the fascinating story of one wartime bomber crew and the part they played in supporting Special Operations Executive's work in Occupied Europe.

USA oplever netop nu det ene forfærdelige skyderi efter det andet på skoler, tankstationer, indkøbscentre og i det offentlige rum. Våbenlovgivningen splitter amerikanerne som aldrig før, og i øjeblikket er der flere våben i USA end der er indbyggere. Hver dag bliver mere end 100 mennesker dræbt og 200 såret i hændelser, hvor der er våben involveret. Disse tal er helt ude af proportioner i forhold til resten af verden, og man må spørge sig selv, hvorfor USA adskiller sig så markant og indtager en førsteplads som det mest voldelige land i den vestlige verden. ”Nationens blod” er en tankevækkende historisk gennemgang af våbenvold i USA af den amerikanske forfatter Paul Auster. I bogen tager han livtag med USA’s våbenkultur og undersøger de kræfter, der har rodfæstet skydevåben dybt i landets nationale identitet. Udgivelsen er en storskrift-udgave til svagsynede i serien MAGNUMBØGER Lindhardt og Ringhof.

Organocatalysis is a promising field of research that has led to the development of many efficient and eco-friendly synthetic methods. Among the different applications of organocatalysis, spirocyclic assembly is of particular interest, as spirocyclic compounds are an important class of organic molecules with a wide range of biological and pharmaceutical activities. The Tamura reaction and 1,3-dipolar cycloaddition are two organocatalytic reactions that have been extensively used for spirocyclic assembly. Electron deficient alkenes are commonly used in these reactions, as they can undergo cycloaddition reactions with dipolarophiles to form a range of spirocyclic compounds. The use of organic catalysts in these reactions has many advantages over traditional metal-based catalysts, including low toxicity, low cost, and easy handling. In addition, organocatalysts can offer high enantioselectivity in many cases, which is crucial in the synthesis of biologically active compounds. Organocatalytic spirocyclic assembly involves the use of various chemical reactions, including Michael addition, acylation, alkylation, Mannich reaction, aldol reaction, Robinson annulation, and many others. The reaction conditions, catalysts, and substrates can all be optimized to achieve high yields and selectivity. The use of chiral organocatalysts can also lead to the synthesis of enantiomerically pure spirocyclic compounds. Lewis base and Brønsted base catalysis are the two main types of organocatalysis used in spirocyclic assembly. Both types of catalysis can offer unique advantages depending on the reaction conditions and substrates used. Moreover, the mechanism of organocatalytic reactions can be elucidated by various techniques, such as NMR spectroscopy, X-ray crystallography, and kinetic studies. The development of efficient and green methods for spirocyclic assembly is an important area of research, as it can lead to the synthesis of novel and biologically active compounds. Organocatalysis is a promising field in this regard, as it offers many advantages over traditional metal-based catalysis. Furthermore, the use of organocatalysts can lead to the development of new reactions and the modification of existing ones, thus expanding the toolbox of synthetic methods available to organic chemists. The work of RaviKiran Donthi and his colleagues in this field is an important contribution to the ongoing efforts to develop efficient and eco-friendly methods for spirocyclic assembly.

The INSTANT New York Times bestseller Instant Los Angeles Times bestsellerOne of NPR's Books We LoveOne of Newsweek Staffers' Favorite Books of the YearShortlisted for the Baillie Gifford Prize“In Nuclear War: A Scenario, Annie Jacobsen gives us a vivid picture of what could happen if our nuclear guardians fail…Terrifying.”—Wall Street Journal There is only one scenario other than an asteroid strike that could end the world as we know it in a matter of hours: nuclear war. And one of the triggers for that war would be a nuclear missile inbound toward the United States.   Every generation, a journalist has looked deep into the heart of the nuclear military establishment: the technologies, the safeguards, the plans, and the risks. These investigations are vital to how we understand the world we really live in—where one nuclear missile will beget one in return, and where the choreography of the world’s end requires massive decisions made on seconds’ notice with information that is only as good as the intelligence we have.   Pulitzer Prize finalist Annie Jacobsen’s Nuclear War: A Scenario explores this ticking-clock scenario, based on dozens of exclusive new interviews with military and civilian experts who have built the weapons, have been privy to the response plans, and have been responsible for those decisions should they have needed to be made. Nuclear War: A Scenario examines the handful of minutes after a nuclear missile launch. It is essential reading, and unlike any other book in its depth and urgency.

Dopo il primo volume sui cannoni italiani, in questa seconda parte tratteremo e completeremo lo studio e l'analisi dei pezzi d'artiglieria ereditati dal primo conflitto mondiale, sia di produzione nazionale che fonti di preda bellica (tipicamente austro-ungarica) a seguito della vittoria nel 1915-18.Il criterio usato sarà ancora quello già utilizzato del calibro a crescere, quindi dai pezzi leggeri in poi. Con il terzo volume che completerà il nostro lavoro sulle artiglierie italiane dei primi cinquanta anni del Novecento tratteremo prevalentemente i mezzi di concezione più moderna, ideati dalla seconda metà degli anni '30. Da questo volume invece parleremo espressamente anche delle bombarde in uso in quegli anni, mentre trattrici e trattori saranno distribuiti in vario modo nei tre volumi in ordine preferibilmente cronologico.

In "Machinery of War: A Comprehensive Study of the Post-9/11 Global Arms Trade," Josh offers an exhaustive exploration into the intricate world of global armaments in the aftermath of the tragic events of September 11, 2001. This seminal work probes the depths of the modern arms trade, revealing its multi-faceted nature, its key players, and its profound impact on the geopolitical landscape. Josh delves into the roles of state actors, private military companies, and non-state entities, underlining their intertwined relationships and the ensuing effects on global security dynamics. With a balanced, objective lens, he navigates through the complexities of cyber warfare, drone technology, and the emergence of autonomous weapons systems, as well as the rise of private military and security companies. Further, he scrutinizes the arms race in different regions, including the Middle East, Asia, Africa, and Latin America, offering a nuanced understanding of their unique circumstances and their roles in the broader arms trade. The author also addresses the significant role of regulatory efforts in the global arms trade, investigating the successes and failures of arms embargoes and international regulations. Lastly, he gazes into the future, offering predictions and identifying trends that may shape the global arms trade in years to come. "Machinery of War" is an indispensable resource for policymakers, researchers, scholars, and anyone interested in understanding the complexities of the global arms trade in the 21st century. This in-depth study invites readers to ponder the geopolitical, ethical, and humanitarian implications of the arms trade, highlighting the urgent need for control and regulation in an increasingly interconnected world.

One high-altitude nuclear detonation will create a massive electromagnetic pulse that can bring down the U.S. national power grid and keep it down for many months, perhaps a year or longer. Americans would instantly find themselves without running water, food, refrigeration, lights, phones, functioning toilets and sewage systems, air conditioning and heating, transportation (no gasoline), and without access to their bank accounts or medical services. A nuclear high-altitude electromagnetic pulse will damage and destroy the modern electronic devices required to run U.S. critical national infrastructure; it will also disable the Emergency Power Systems and active Emergency Core Cooling Systems at dozens of U.S. nuclear power plants, causing the meltdown of their nuclear reactors. All legislative efforts to protect the grid and critical national infrastructure from electromagnetic pulse have been blocked by the electric and nuclear utilities, as well as by the Nuclear Regulatory Commission.

Deadly Ingenuity: A History of Unusual Weapons from Around the World and Across Time does something new in the study of weaponry and martial arts. It traverses the centuries and continents while focusing exclusively on fighting tools that are not the usual suspects. It also brings to light some historical weapons and fighting techniques that have never before been surveyed. The diverse panoply of objects takes the reader from islands (Hawaii, Okinawa, New Zealand), to plains (Argentina, the American Southwest) and from jungles (Borneo, Brazil) to cities (New York City, London, Seoul, Tokyo, Venice). Nor are those complete lists. Sources include but are not limited to Chinese and Japanese martial arts texts, Irish mythology, Victorian crime blotters, naval history, Greek classics, Roman historians, the memoirs of English knights and 21st century headlines. Robert Escobar's first weapons book was praised by an American History professor, an award winning author, an archeologist, a legendary weapons author and others. He worked feverishly to ensure this work is a worthy follow-up.
