This book describes a robust, low-cost electrochemical sensing system that is able to detect hormones and phthalates – the most ubiquitous endocrine disruptor compounds – in beverages and is sufficiently flexible to be readily coupled with any existing chemical or biochemical sensing system. A novel type of silicon substrate-based smart interdigital transducer, developed using MEMS semiconductor fabrication technology, is employed in conjunction with electrochemical impedance spectroscopy to allow real-time detection and analysis. Furthermore, the presented interdigital capacitive sensor design offers a sufficient penetration depth of the fringing electric field to permit bulk sample testing. The authors address all aspects of the development of the system and fully explain its benefits. The book will be of wide interest to engineers, scientists, and researchers working in the fields of physical electrochemistry and biochemistry at the undergraduate, postgraduate, and research levels. It will also be highly relevant for practitioners and researchers involved in the development of electromagnetic sensors.
A field-changing history explains how the subcontinent lost its political identity as the home of all religions and emerged as India, the land of the Hindus. Did South Asia have a shared regional identity prior to the arrival of Europeans in the late fifteenth century? This is a subject of heated debate in scholarly circles and contemporary political discourse. Manan Ahmed Asif argues that Pakistan, Bangladesh, and the Republic of India share a common political ancestry: they are all part of a region whose people understand themselves as Hindustani. Asif describes the idea of Hindustan, as reflected in the work of native historians from roughly 1000 CE to 1900 CE, and how that idea went missing. This makes for a radical interpretation of how India came to its contemporary political identity. Asif argues that a European understanding of India as Hindu has replaced an earlier, native understanding of India as Hindustan, a home for all faiths. Turning to the subcontinent’s medieval past, Asif uncovers a rich network of historians of Hindustan who imagined, studied, and shaped their kings, cities, and societies. Asif closely examines the most complete idea of Hindustan, elaborated by the early seventeenth century Deccan historian Firishta. His monumental work, Tarikh-i Firishta, became a major source for European philosophers and historians, such as Voltaire, Kant, Hegel, and Gibbon during the eighteenth and nineteenth centuries. Yet Firishta’s notions of Hindustan were lost and replaced by a different idea of India that we inhabit today. The Loss of Hindustan reveals the intellectual pathways that dispensed with multicultural Hindustan and created a religiously partitioned world of today.
A stunning history of Pakistan’s cultural and intellectual capital, from one of the preeminent scholars of South Asia The city of Lahore was more than one thousand years old when it went through a violent schism. As the South Asian subcontinent was partitioned in 1947 to gain freedom from Britain’s colonial hold, and the Islamic Republic of Pakistan was formed, the city’s large Hindu and Sikh populations were pushed toward India, and an even larger Muslim refugee population settled in the city. This was just the latest in a long history of the city’s making and unmaking. Over the centuries, the city has kept a firm grip on the imagination of travelers, poets, writers, and artists. More recently, it has been journalists who have been drawn to the city as a focal point for a nation that continues to grab international headlines. For this book, acclaimed historian Manan Ahmed Asif brings to life a diverse and vibrant world by walking the city again and again over the course of many years. Along the way he joins Sufi study circles and architects doing restoration in the medieval parts of Lahore and speaks with a broad range of storytellers and historians. To this Asif juxtaposes deep analysis of the city’s centuries-old literary culture, noting how it reverberates among the people of Lahore today. To understand modern Pakistan requires understanding its cultural capital, and Disrupted City uses Lahore’s cosmopolitan past and its fractured present to provide a critical lens to challenge the grand narratives of the Pakistani nation-state and its national project of writing history.
