Organic Synthesis : The Disconnection Approach
One approach to organic synthesis is retrosynthetic analysis.With this approach a chemist will start with the structure of their target molecule and progressively cut bonds to create simpler molecules.Reversing this process gives a synthetic route to the target molecule from simpler starting materials.This “disconnection” approach to synthesis is now a fundamental part of every organic synthesis course. Organic Synthesis: The Disconnection Approach, 2nd Edition introduces this important technique, to help students to design their own organic syntheses.There are forty chapters: those on the synthesis of given types of molecules alternate with strategy chapters in which the methods just learnt are placed in a wider context.The synthesis chapters cover many ways of making each type of molecule starting with simple aromatic and aliphatic compounds with one functional group and progressing to molecules with many functional groups.The strategy chapters cover questions of selectivity, protection, stereochemistry, and develop more advanced thinking via reagents specifically designed for difficult problems. Examples are drawn from pharmaceuticals, agrochemicals, natural products, pheromones, perfumery and flavouring compounds, dyestuffs, monomers, and intermediates used in more advanced synthetic work.Reasons for wishing to synthesise each compound are given. This second edition has been fully revised and updated with a modern look.Recent examples and techniques are included and illustrated additional material has been added to take the student to the level required by the sequel, “Organic Synthesis: Strategy and Control”. Several chapters contain extensive new material based on courses that the authors give to chemists in the pharmaceutical industry. Organic Synthesis: The Disconnection Approach, 2nd edition provides a full course in retrosynthetic analysis for chemistry and biochemistry students and a refresher for organic chemists working in industry and academia.

Workbook for Organic Synthesis: The Disconnection Approach, 2nd Edition This workbook provides a comprehensive graded set of problems to illustrate and develop the themes of each of the chapters in the textbook Organic Synthesis: The Disconnection Approach, 2nd Edition.Each problem is followed by a fully explained solution and discussion.The examples extend the student’s experience of the types of molecules being synthesised by organic chemists, and the strategies they employ to control their syntheses.By working through these examples students will develop their skills in analysing synthetic challenges, and build a toolkit of strategies for planning new syntheses.Examples are drawn from pharmaceuticals, agrochemicals, natural products, pheromones, perfumery and flavouring compounds, dyestuffs, monomers, and intermediates used in more advanced synthetic work.Reasons for wishing to synthesise each compound are given.Together the workbook and textbook provide a complete course in retrosynthetic analysis.

Digital Lethargy : Dispatches from an Age of Disconnection
The exhaustion, disappointment, and listlessness experienced under digital capitalism, explored through works by contemporary artists, writers, and performers. Sometimes, interacting with digital platforms, we want to be passive—in those moments of dissociation when we scroll mindlessly rather than connecting with anyone, for example, or when our only response is a shrugging “lol.” Despite encouragement by these platforms to “be yourself,” we want to be anyone but ourselves.Tung-Hui Hu calls this state of exhaustion, disappointment, and listlessness digital lethargy.This condition permeates our lives under digital capitalism, whether we are “users,” who are what they click, or racialized workers in Asia and the Global South.Far from being a state of apathy, however, lethargy may hold the potential for social change. Hu explores digital lethargy through a series of works by contemporary artists, writers, and performers.These dispatches from the bleeding edge of digital culture include a fictional dystopia where low-wage Mexican workers laugh and emote for white audiences; a group that invites lazy viewers to strap their Fitbits to a swinging metronome, faking fitness and earning a discount on their health insurance premiums; and a memoir of burnout in an Amazon warehouse.These works dwell within the ordinariness and even banality of digital life, redirecting our attention toward moments of thwarted agency, waiting and passing time.Lethargy, writes Hu, is a drag: it weighs down our ability to rush to solutions, and forces us to talk about the unresolved present.

What is a disconnection lock?
A disconnection lock is a safety device used to prevent the accidental or unauthorized use of equipment or machinery. It typically involves physically locking a switch or control mechanism in the off position to ensure that the equipment cannot be operated. Disconnection locks are commonly used in industrial settings to protect workers from harm during maintenance or repair work. They are an important part of ensuring workplace safety and compliance with regulations.

Constant Disconnection : The Weight of Everyday Digital Life
The weight of constant digital connection is the default condition of working life, home life, and everyday personal life – driving us to engage more with platforms than with people, a new state of constant disconnection that we cannot escape.Overflowing email inboxes, deluges of mobile phone notifications and torrents of social media posts—the flow of communication in its abundance is today's individualized interface for interpersonal and professional practices. Communication technologies and their use are both the needle and the thread of the wider social tapestry of everyday contemporary life.This ever-changing communication environment is where the neoliberal economic policies of the West and the commercial imperatives of the platform and data-mining industries meet.It is where the contradictions they produce can be felt day-to-day by citizens-turned-users.How does it feel to live at the pressure points of intersecting economic realities and why does it matter?Drawing on extensive sociological research, Burchell examines how individuals try to manage connection as participation in everyday life and how, on a larger scale, the ever-expanding knowledge, communication, and data-driven economies depend on the very pressures that result from our disparate communication needs.With so much time spent managing the pressures of our communication environment, we often overlook the way media technologies produce systemic tensions that are reshaping how we interact with each other and what we understand to be social connection today.
