Terahertz Technology: Principles and Applications in the Agri-Food Industry
by T. Anukiruthika Digvir S. JayasTerahertz (THz) technology is an active area of research, but only in recent years has the application of THz waves (T waves) in food and agricultural industries been explored. Terahertz Technology: Principles and Applications in the Agri-Food Industry describes the operating principles of THz technology and discusses applications and advantages of the THz regime of the electromagnetic spectrum for use in the agri-food industry. The agri-food industry is focusing on the development of non-destructive quality evaluation techniques that can provide accurate analysis quickly and are environmentally friendly. Among such techniques is THz technology that provides a novel noninvasive approach to quality assessment and safety assurance of agri-food products. The low energy of T waves is best suited for the analysis of sensitive biomaterials and does not cause photoionization. Therefore, THz imaging is complementary to X-ray imaging. Although accessing the THz spectrum is tedious by conventional devices, the combination of optics and electronics principles has opened a dimension of research in this field. This book provides an overview of THz spectroscopy and imaging, system components, types of THz systems, and applications and advantages of THz for applications in the agri-food industry. It describes the basic working mechanism, operating principle, operation modes, and system components of THz spectroscopy and imaging. Various advancements in THz technology related to agricultural and food applications are discussed that could serve as a guidebook for all those working and interested in non-destructive food assessment techniques. Key Features: Explores broader applications of the THz regime in the agri-food sector Describes system components, different forms of THz systems, and the working principle of T waves for spectroscopic and imaging techniques Provides insights on future research needs for industrial implementation of THz technology Complements the knowledge of other existing non-destructive spectroscopy and imaging techniques for food analysis Although books on biomedical applications of THz have been published, no book is available that deals with applications in the agri-food industry. Hence, Terahertz Technology is beneficial for undergraduate and graduate students and those food industry professionals involved in research related to non-destructive quality assessment and imaging techniques.

El tercer testamento
by Christopher Galt¿Y si tu futuro ya ha sucedido y todos tus recuerdos son mentira...? Un extraño acontecimiento se reproduce en todo el mundo: la gente ha empezado a tener visiones que los llevan a situaciones del pasado o el futuro, que los aterrorizan y conmueven. Hasta pueden experimentar físicamente aquello que creen que están viviendo. Nadie entiende lo que sucede. Nadie está a salvo. En un mundo en que la ciencia se ha constituido como garante del conocimiento y la razón no deja lugar a explicaciones que parecerían esotéricas, estos acontecimientos inexplicables no tienen cabida. Y sin embargo, sí que están sucediendo. Lo que parece una epidemia de alucinaciones se extiende por todo el globo y no respeta fronteras, razas, edad, sexo o condición de cordura. Ni siquiera existe un común denominador que permita tirar del hilo para descubrir cuál es la enfermedad que las causa, si la hubiera.¿Será posible que la historia haya encontrado la manera de repetirse incesablemente? ¿Tendrá todo esto que ver con el proyecto de neurociencia en el que participa John Macbeth y que busca crear una inteligencia artificial autónoma? De Estados Unidos a Dinamarca, de China a Alemania, el mundo se ha vuelto loco y Macbeth parece el único capaz de llegar a averiguar qué está sucediendo.
