direct analysis in real time: Reducing the Threat of Improvised Explosive Device Attacks by Restricting Access to Explosive Precursor Chemicals National Academies of Sciences, Engineering, and Medicine, Division on Earth and Life Studies, Board on Chemical Sciences and Technology, Committee on Reducing the Threat of Improvised Explosive Device Attacks by Restricting Access to Chemical Explosive Precursors, 2018-05-19 Improvised explosive devices (IEDs) are a type of unconventional explosive weapon that can be deployed in a variety of ways, and can cause loss of life, injury, and property damage in both military and civilian environments. Terrorists, violent extremists, and criminals often choose IEDs because the ingredients, components, and instructions required to make IEDs are highly accessible. In many cases, precursor chemicals enable this criminal use of IEDs because they are used in the manufacture of homemade explosives (HMEs), which are often used as a component of IEDs. Many precursor chemicals are frequently used in industrial manufacturing and may be available as commercial products for personal use. Guides for making HMEs and instructions for constructing IEDs are widely available and can be easily found on the internet. Other countries restrict access to precursor chemicals in an effort to reduce the opportunity for HMEs to be used in IEDs. Although IED attacks have been less frequent in the United States than in other countries, IEDs remain a persistent domestic threat. Restricting access to precursor chemicals might contribute to reducing the threat of IED attacks and in turn prevent potentially devastating bombings, save lives, and reduce financial impacts. Reducing the Threat of Improvised Explosive Device Attacks by Restricting Access to Explosive Precursor Chemicals prioritizes precursor chemicals that can be used to make HMEs and analyzes the movement of those chemicals through United States commercial supply chains and identifies potential vulnerabilities. This report examines current United States and international regulation of the chemicals, and compares the economic, security, and other tradeoffs among potential control strategies. |

direct analysis in real time: Celebrity Politics Mark Wheeler, 2013-08-22 In this new book, Mark Wheeler offers the first in-depth analysis of the history, nature and global reach of celebrity politics today. Celebrity politicians and politicized celebrities have had a profound impact upon the practice of politics and the way in which it is now communicated. New forms of political participation have emerged as a result and the political classes have increasingly absorbed the values of celebrity into their own PR strategies. Celebrity activists, endorsers, humanitarians and diplomats also play a part in reconfiguring politics for a more fragmented and image-conscious public arena. In academic circles, celebrity may be viewed as a ‘manufactured product’; one fabricated by media exposure so that celebrity activists are no more than ‘bards of the powerful.’ Mark Wheeler, however, provides a more nuanced critique contending that both celebrity politicians and politicized stars should be defined by their ‘affective capacity’ to operate within the public sphere. This timely book will be a valuable resource for students of media and communication studies and political science as well as general readers keen to understand the nature and reach of contemporary celebrity culture. |
direct analysis in real time: Industry 5.0 and Paradigm Shift—Emerging Challenges Namit Gupta, Roopa Shinde, Rakesh Kumar Malviya, Anjali Gupta, 2023-01-23 Industry 5.0 is the successor of the 'Industry 4.0' concept which employed high technology in the manufacturing industry. Industry 5.0 is a new idea that adds a human touch to the work of robots and smart machines. The basic idea of humans and machines working together is to increase efficiency and effectivity, like the 'Internet of things' (loT). It aims to merge the increasing cognitive computing abilities of the robots with the intelligence and resourcefulness of the humans. The progress of Industry 5.0 is inevitable. As the technology grows more each day, we find ways to make our work simpler. The development of such technologies to make the world more efficient requires its manufacturers, i.e., humans who collaborate with these machines and technologies. Humans are indispensable resources, as what a machine can do is limited. And with all these efficiencies we have come so far, there is no path leading us back. With adoption of new concepts comes a paradigm shift as development continues and we move from Industry 4.0 which speaks of the future of production, its primary purpose continues to be achieving seamless connectivity between machines and IT systems for higher productivity and efficiencies across the value chain. Overall, it focuses mainly on traditional financial and operational KPIs. Whereas Industry 5.0 gives a human touch to the concept of 4.0 keeping in mind the well-being of the environment and society, making the machines and humans work together on a path of 'Green Future'. Industry 5.0 has the balance of both humans and technologies which benefits the ecosystem, with discovery of new energy sources and renewable resources, helping in a sustainable working environment. It can be used to reduce harmful residue caused due to manufacturing processes and recycle rare materials. Taking this theme, the multidisciplinary congress on Industry 5.0 and Paradigm Shift: Emerging Challenges will highlight research challenges and open issues that should be further developed to realize Industry 5.0. |

direct analysis in real time: The Prophets Robert Jones, Jr., 2021-01-05 Best Book of the Year NPR • The Washington Post • Boston Globe • TIME • USA Today • Entertainment Weekly • Real Simple • Parade • Buzzfeed • Electric Literature • LitHub • BookRiot • PopSugar • Goop • Library Journal • BookBub • KCRW • Finalist for the National Book Award • One of the New York Times Notable Books of the Year • One of the New York Times Best Historical Fiction of the Year • Instant New York Times Bestseller A singular and stunning debut novel about the forbidden union between two enslaved young men on a Deep South plantation, the refuge they find in each other, and a betrayal that threatens their existence. Isaiah was Samuel's and Samuel was Isaiah's. That was the way it was since the beginning, and the way it was to be until the end. In the barn they tended to the animals, but also to each other, transforming the hollowed-out shed into a place of human refuge, a source of intimacy and hope in a world ruled by vicious masters. But when an older man—a fellow slave—seeks to gain favor by preaching the master's gospel on the plantation, the enslaved begin to turn on their own. Isaiah and Samuel's love, which was once so simple, is seen as sinful and a clear danger to the plantation's harmony. With a lyricism reminiscent of Toni Morrison, Robert Jones, Jr., fiercely summons the voices of slaver and enslaved alike, from Isaiah and Samuel to the calculating slave master to the long line of women that surround them, women who have carried the soul of the plantation on their shoulders. As tensions build and the weight of centuries—of ancestors and future generations to come—culminates in a climactic reckoning, The Prophets fearlessly reveals the pain and suffering of inheritance, but is also shot through with hope, beauty, and truth, portraying the enormous, heroic power of love. |

direct analysis in real time: Fast Liquid Chromatography-mass Spectrometry Methods In Food And Environmental Analysis Oscar Nunez, Hector Gallart-ayala, Claudia P B Martins, Paolo Lucci, 2015-02-03 There is a growing need for high-throughput separations in food and environmental research that are able to cope with the analysis of a large number of compounds in very complex matrices. Whereas the most common approach for solving many analytical problems has often been high-performance liquid chromatography (HPLC), the recent use of fast or ultra-fast chromatographic methods for environmental and food analysis has increased the overall sample throughput and laboratory efficiency without loss (and even with an improvement) in the resolution obtained by conventional HPLC systems.This book brings together researchers at the top of their field from across the world to discuss and analyze recent advances in fast liquid chromatography-mass spectrometry (LC-MS) methods in food and environmental analysis. First, the most novel approaches to achieve fast and ultra-fast methods as well as the use of alternative and complementary stationary phases are described. Then, recent advances in fast LC-MS methods are addressed, focusing on novel treatment procedures coupled with LC-MS, new ionization sources, high-resolution mass spectrometry, and the problematic confirmation and quantification aspects in mass spectrometry. Finally, relevant LC-MS applications in food and environmental analysis such as the analysis of pesticides, mycotoxins, food packaging contaminants, perfluorinated compounds and polyphenolic compounds are described.The scope of the book is intentionally broad and is aimed at worldwide analytical laboratories working in food and environmental applications as well as researchers in universities worldwide. |
direct analysis in real time: Electrospray Ionization Mass Spectrometry Richard B. Cole, 1997-05-06 Comprehensive, up-to-date coverage of a revolutionary technique Electrospray ionization mass spectrometry (ESI-MS) has completely changed the way physicists, chemists, and biologists view the study of large molecules. The technique derives detailed information about molecular weights and structures from extremely small sample quantities. ESI-MS can create highly charged forms of very high molecular weight compounds, it is naturally compatible with many types of separation techniques, and it allows noncovalent interactions between molecules in solution to be preserved in the gas phase. But many researchers may not use the technique to its full potential because they are unfamiliar with the different perspectives of its underlying processes, the varied approaches to implementation, and the wide-ranging utility of the technique. In this book, Richard B. Cole and an assemblage of leading researchers present a single-volume compilation of different approaches to the understanding and exploitation of ESI-MS. This comprehensive guide: * Examines the physical and chemical aspects of the electrospray process and describes the events involved in ion formation as well as the electro-chemical phenomena that are central to charged droplet formation during the process * Explores the coupling of electrospray ionization to various mass spectrometers, including quadrupole, magnetic, time-of-flight, quadrupole ion trap, and Fourier transform ion cyclotron resonance instruments * Describes recent progress in interfacing ESI with solution-based separation techniques, including liquid chromatography and capillary electrophoresis * Charts the rapid development of ESI applications and categorizes them by compound type: peptides and proteins, nucleic acids and their constituents, carbohydrates and lipids, small molecules related to pharmacology and drug metabolism, and organometallics and inorganic compounds Electrospray Ionization Mass Spectrometry is the indispensable handbook and reference for anyone who wishes to understand, implement, or apply this technique, including researchers in chemistry, metallochemistry, biochemistry, biology, pharmacology, and physics. |
direct analysis in real time: Lord of the Flies William Golding, 2012-09-20 A plane crashes on a desert island and the only survivors, a group of schoolboys, assemble on the beach and wait to be rescued. By day they inhabit a land of bright fantastic birds and dark blue seas, but at night their dreams are haunted by the image of a terrifying beast. As the boys' delicate sense of order fades, so their childish dreams are transformed into something more primitive, and their behaviour starts to take on a murderous, savage significance. First published in 1954, Lord of the Flies is one of the most celebrated and widely read of modern classics. Now fully revised and updated, this educational edition includes chapter summaries, comprehension questions, discussion points, classroom activities, a biographical profile of Golding, historical context relevant to the novel and an essay on Lord of the Flies by William Golding entitled 'Fable'. Aimed at Key Stage 3 and 4 students, it also includes a section on literary theory for advanced or A-level students. The educational edition encourages original and independent thinking while guiding the student through the text - ideal for use in the classroom and at home. |
direct analysis in real time: Gene Quantification Francois Ferre, 2012-12-06 Geneticists and molecular biologists have been interested in quantifying genes and their products for many years and for various reasons (Bishop, 1974). Early molecular methods were based on molecular hybridization, and were devised shortly after Marmur and Doty (1961) first showed that denaturation of the double helix could be reversed - that the process of molecular reassociation was exquisitely sequence dependent. Gillespie and Spiegelman (1965) developed a way of using the method to titrate the number of copies of a probe within a target sequence in which the target sequence was fixed to a membrane support prior to hybridization with the probe - typically a RNA. Thus, this was a precursor to many of the methods still in use, and indeed under development, today. Early examples of the application of these methods included the measurement of the copy numbers in gene families such as the ribosomal genes and the immunoglo bulin family. Amplification of genes in tumors and in response to drug treatment was discovered by this method. In the same period, methods were invented for estimating gene num bers based on the kinetics of the reassociation process - the so-called Cot analysis. This method, which exploits the dependence of the rate of reassociation on the concentration of the two strands, revealed the presence of repeated sequences in the DNA of higher eukaryotes (Britten and Kohne, 1968). An adaptation to RNA, Rot analysis (Melli and Bishop, 1969), was used to measure the abundance of RNAs in a mixed population. |

direct analysis in real time: Mass Spectrometry Imaging in Food Analysis Leo M.L. Nollet, 2020-04-29 Food contains various compounds and many technologies exist to analyze those molecules of interest. However, the analysis of the spatial distribution of those compounds using conventional technology, such as liquid chromatography-mass spectrometry or gas chromatography-mass spectrometry is difficult. Mass spectrometry imaging (MSI) is a mass spectrometry technique to visualize the spatial distribution of molecules, as biomarkers, metabolites, peptides or proteins by their molecular masses. Despite the fact that MSI has been generally considered a qualitative method, the signal generated by this technique is proportional to the relative abundance of the analyte and so quantification is possible. Mass Spectrometry Imaging in Food Analysis, a volume in the Food Analysis and Properties Series, explains how the novel use of matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) will be an ideal complementary approach. MALDI-MSI is a two-dimensional MALDI-MS technology that can detect compounds in a tissue section without extraction, purification, separation, or labeling. It can be used to visualize the spatial distribution of biomolecules in foods. Features: Explains the novel use of matrix-assisted laser desorption/ionization mass spectrometry imaging in food analysis Describes how MALDI-MSI will be a useful technique for optical quality assurance. Shows how MALDI-MSI detects food contaminants and residues Covers the historical development of the technology While there are a multitude of books on mass spectrometry, none focus on food applications and thus this book is ideally suited to food scientists, food industry personnel engaged in product development, research institutions, and universities active in food analysis or chemical analysis. Also available in the Food Analysis and Properties Series: Food Aroma Evolution: During Food Processing, Cooking, and Aging, edited by Matteo Bordiga and Leo M.L. Nollet (ISBN: 9781138338241) Ambient Mass Spectroscopy Techniques in Food and the Environment, edited by Leo M.L. Nollet and Basil K.
