Volume 6: Ionization Methods

Volume 6 captures the story of molecular ionization and its phenomenal evolution that makes mass spectrometry the powerful method it is today. Chapters 1 and 2 cover fundamentals and various issues that are common to all ionization (e.g., accurate mass, isotope clusters, and derivatization).

Chapters 3-9 acknowledge that some ionization methods are appropriate for gas-phase molecules and others for molecules that are in the solid or liquid states. Chapters 3-6 cover gas-phase molecules, dividing the subject into: (1) ionization of gas-phase molecules by particles (e.g., EI), (2) ionization by photons, (3) ionization by ion-molecule and molecule-molecule reactions (e.g., APCI and DART), and ionization in Strong electric fields (i.e., Electrohydrodynamic and Field Ionization/Desorption).

"Ionization in a Strong Electric Field" illustrates the transition to ionization of molecules in the solid or liquid states, covered in Chapters 7-9: (1) spray methods for ionization (e.g., electrospray), (2) desorption ionization by particle bombardment (e.g., FAB), and (3) desorption by photons (e.g., MALDI). Electrospray and MALDI also lead to applications in biophysical chemistry, the theme of Chapter 10.

Chapter 11 reconsiders ionization from the view of choosing an ionization method. The range of subjects is from ionization of organic and biomolecules to the study of microorganisms.
* reviews range of ionization methods used in mass spectrometry today
* includes tutorials describing the principles and instrumentation applied to each method
* considers appropriate methods of ionization for analysis of various substances

As asymmetric 'wars among the people' replace state-on-state wars in modern armed conflict, the growing role of military medicine and medical technology in contemporary war fighting has brought an urgent need to critically reassess the theory and practice of military medical ethics. Military Medical Ethics for the 21st Century is the first full length, broad-based treatment of this important subject. Written by an international team of practitioners and academics, this book provides interdisciplinary insights into the major issues facing military-medical decision makers and critically examines the tensions and dilemmas inherent in the military and medical professions. In this book the authors explore the practice of battlefield bioethics, medical neutrality and treatment of the wounded, enhancement technologies for war fighters, the potential risks of dual-use biotechnologies, patient rights for active duty personnel, military medical research and military medical ethics education in the 21st Century.

The focus of Volume 2 of the Encyclopedia of Mass Spectrometry is on peptides and proteins, separation techniques, preparation protocols, and the fundamental characteristics as ionic gas phase species that lie within the breadth of the field of mass spectrometry. This volume is divided into four sections; experimental approaches and protocols, sequence analysis, other structural analyses, and targeted applications.
* Frontier Research on biological, biochemical, and biomedical applications of MS
* Focus on Peptides and Proteins
* Suitable for new graduate students entering the field

Discussing strategies to determine the structure and machanisms of numerous compound classics, this book covers new chemical and elctrophoretic techniques for rapid sample preconcentration and separation. It summarizes breakthroughs in the theory and instrumentation of electrospray mass spectrometry in pharmaceutical and biomedical applications, provides practical examples for the characterization of peptides, proteins, and glycoproteins, includes applications in proteomics, combinatorial chemistry, and drug characterization. Topics include chemical and electrophoretic techniques for rapid sample preconcentration and separation, screening processes for proteins from libraries of compounds, protein folding and dynamics, and more.

As insurgencies rage, a burning question remains: how should insurgents fight technologically superior state armies? Commentators rarely ask this question because the catchphrase 'we fight by the rules, but they don't' is nearly axiomatic. But truly, are all forms of guerrilla warfare equally reprehensible? Can we think cogently about just guerrilla warfare? May guerrilla tactics such as laying improvised explosive devices (IEDs), assassinating informers, using human shields, seizing prisoners of war, conducting cyber strikes against civilians, manipulating the media, looting resources, or using nonviolence to provoke violence prove acceptable under the changing norms of contemporary warfare? The short answer is 'yes', but modern guerrilla warfare requires a great deal of qualification, explanation, and argumentation before it joins the repertoire of acceptable military behavior. Not all insurgents fight justly, but guerrilla tactics and strategies are also not always the heinous practices that state powers often portray them to be.

Beleaguered countries struggling against aggression or powerful nations defending others from brutal regimes mobilize medicine to wage just war. As states funnel medical resources to maintain unit readiness and conserve military capabilities, numerous ethical challenges foreign to peacetime medicine result. Force conservation drives combat hospitals to prioritize warfighter care over all others. Civilians find themselves bereft of medical attention; prison officials force feed hunger-striking detainees; policymakers manage healthcare to win the hearts and minds of local nationals; and scientists develop neuro-technologies or nanosurgery to create super soldiers. When the fighting ends, intractable moral dilemmas rebound. Post-war justice demands enormous investments of time, resources and personnel. But losing interest and no longer zealous, war-weary nations forget their duties to rebuild ravaged countries abroad and rehabilitate their war-torn veterans at home. Addressing these incendiary issues, Military Medical Ethics in Contemporary Armed Conflict integrates the ethics of medicine and the ethics of war. Medical ethics in times of war is not identical to medical ethics in times of peace, but a unique discipline. Without war, there is no military medicine, and without just war there is no military medical ethics. Military Medical Ethics in Contemporary Armed Conflict revises, defends, and rebuts wartime medical practices, just as it lays the moral foundation for casualty care in future conflicts.

Just war theory focuses primarily on bodily harm, such as killing, maiming, and torture, while other harms are often largely overlooked. At the same time, contemporary international conflicts increasingly involve the use of unarmed tactics, employing 'softer' alternatives or supplements to kinetic power that have not been sufficiently addressed by the ethics of war or international law. Soft war tactics include cyber-warfare and economic sanctions, media warfare, and propaganda, as well as non-violent resistance as it plays out in civil disobedience, boycotts, and 'lawfare.' While the just war tradition has much to say about 'hard' war - bullets, bombs, and bayonets - it is virtually silent on the subject of 'soft' war. Soft War: The Ethics of Unarmed Conflict illuminates this neglected aspect of international conflict.

Asymmetric conflict is changing the way that we practise and think about war. Torture, rendition, assassination, blackmail, extortion, direct attacks on civilians, and chemical weapons are all finding their way to the battlefield despite longstanding international prohibitions. This book offers a practical guide for policy makers, military officers, students, and others who ask such questions as: Do guerillas deserve respect or long jail sentences? Are there grounds to torture guerillas for information or assassinate them on the battlefield? Is there room for nonlethal weapons to subdue militants and safeguard the lives of noncombatants? Who are noncombatants in asymmetric war? What is the status of civilians who shelter and aid guerillas? And, do guerillas have any right to attack civilians, particularly those who aid and shelter members of the stronger army? If one side can expand the scope of civilian vulnerability, then why can t the other? To read and comment on Michael Gross's blog article on the UN Human Rights Council Report on Gaza, click here

Responsible citizens are expected to combine ethical judgement with judiciously exercised social activism to preserve the moral foundation of democratic society and prevent political injustice. But do they? Utilizing a research model integrating insights from rational choice theory and cognitive developmental psychology this book, first published in 1997, carefully explores three exemplary cases of morally inspired activism: Jewish rescue in wartime Europe, abortion politics in the United States, and peace and settler activism in Israel. From all three analyses a single conclusion emerges: the most politically competent individuals are, most often, the least morally competent. This is the central paradox of political morality. These findings cast doubt on strong models of political morality characterized by enlightened moral reasoning and concerted political action while affirming alternative weak models that fuse activism with sectarian moral interests. They provide empirical support to further upend the liberal vision of democratic character, education, and society.
