Download or read book Movie Mutations written by Jonathan Rosenbaum and published by Bloomsbury Publishing. This book was released on 2019-07-25 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea of cinephilia is a crucial one for students of the cinema, but it is often associated with a bygone arthouse era. At the beginning of the twenty-first century, corporatism, public relations and bottom-line accounting seem to govern mainstream film-making. Formula-driven Hollywood blockbusters dominate the world marketplace. In times like these can 'the love of cinema' still flourish? In fact contemporary cinema is stunningly varied and rich. From Taiwan and Iran to Brazil and the Baltic states, it is flourishing and constantly mutating. Directors like Abbas Kiarostami, Hou Hsiao-hsien and Tsai Ming-liang are making extraordinary films that are the equal of the great classics, previously unrecognised works from the past are being discovered, and new definitions and boundaries of genres are being formulated. Even when this work is not widely distributed it is seen at film festivals on every continent and available on DVD; and it is being discussed in a proliferating number of print and web publications. Those who follow and share such work, as contributors from around the world demonstrate in this book, are forming new kinds of critical communities that enable significant exchanges between cultures at a time when other forces seem bent on keeping them mutually isolated. In contrast to any talk of 'the death of cinema', Movie Mutations pronounces the art form alive, well, and still developing in new and unforeseen directions. In weaving together transnational discussions and debates, Movie Mutations shows why the idea of cinephilia is just as relevant today as it ever was.

Download or read book Semiconductor based Sensors written by Fan Ren and published by World Scientific. This book was released on 2016-08-26 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive summary of the status of emerging sensor technologies and provides a framework for future advances in the field. Chemical sensors have gained in importance in the past decade for applications that include homeland security, medical and environmental monitoring and also food safety. A desirable goal is the ability to simultaneously analyze a wide variety of environmental and biological gases and liquids in the field and to be able to selectively detect a target analyte with high specificity and sensitivity. The goal is to realize real-time, portable and inexpensive chemical and biological sensors and to use these as monitors for handheld gas, environmental pollutant, exhaled breath, saliva, urine, or blood, with wireless capability.In the medical area, frequent screening can catch the early development of diseases, reduce the suffering of patients due to late diagnoses, and lower the medical cost. For example, a 96% survival rate has been predicted in breast cancer patients if the frequency of screening is every three months. This frequency cannot be achieved with current methods of mammography due to high cost to the patient and invasiveness (radiation). In the area of detection of medical biomarkers, many different methods, including enzyme-linked immunsorbent assay (ELISA), particle-based flow cytometric assays, electrochemical measurements based on impedance and capacitance, electrical measurement of microcantilever resonant frequency change, and conductance measurement of semiconductor nanostructures, gas chromatography (GC), ion chromatography, high density peptide arrays, laser scanning quantitiative analysis, chemiluminescence, selected ion flow tube (SIFT), nanomechanical cantilevers, bead-based suspension microarrays, magnetic biosensors and mass spectrometry (MS) have been employed. Depending on the sample condition, these methods may show variable results in terms of sensitivity for some applications and may not meet the requirements for a handheld biosensor.

Download or read book The Greek Myths written by Robert Graves and published by Penguin. This book was released on 2012-04-24 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: Robert Graves, classicist, poet, and unorthodox critic, retells the Greek legends of gods and heroes for a modern audience And, in the two volumes of The Greek Myths, he demonstrates with a dazzling display of relevant knowledge that Greek Mythology is “no more mysterious in content than are modern election cartoons.” His work covers, in nearly two hundred sections, the creation myths; the legends of the births and lives of the great Olympians; the Theseus, Oedipus, and Heracles cycles; the Argonaut voyage; the tale of Troy, and much more. All the scattered elements of each myth have been assembled into a harmonious narrative, and many variants are recorded which may help to determine its ritual or historical meaning, Full references to the classical sources, and copious indexes, make the book as valuable to the scholar as to the general reader; and a full commentary on each myth explains and interprets the classical version in the light of today’s archaeological and anthropological knowledge.
Download or read book The Politics of Dependency written by Martha Menchaca and published by University of Texas Press. This book was released on 2016-06-14 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States and Mexico trade many commodities, the most important of which are indispensable sources of energy—crude oil and agricultural labor. Mexican oil and workers provide cheap and reliable energy for the United States, while US petro dollars and agricultural jobs supply much-needed income for the Mexican economy. Mexico’s economic dependence on the United States is well-known, but The Politics of Dependency makes a compelling case that the United States is also economically dependent on Mexico. Expanding dependency theory beyond the traditional premise that weak countries are dominated by powerful ones, Martha Menchaca investigates how the United States and Mexico have developed an asymmetrical codependency that disproportionally benefits the United States. In particular, she analyzes how US foreign policy was designed to enable the US government to help shape the development of Mexico’s oil industry, as well as how migration from Mexico to the United States has been regulated by the US Congress to ensure that American farmers have sufficient labor. This unprecedented dual study of energy sectors that are usually examined in isolation reveals the extent to which the United States has become economically dependent on Mexico, even as it remains the dominant partner in the relationship. It also exposes the long-term effects of the agricultural policies of NAFTA, which led to the unemployment of millions of agricultural workers in Mexico, a large percentage of whom relocated to the United States.
