Explores the use of conventional and novel technologies to enhance fermentation processes Fermentation Processes reviews the application of both conventional and emerging technologies for enhancing fermentation conditions, examining the principles and mechanisms of fermentation processes, the microorganisms used in bioprocesses, their implementation in industrial fermentation, and more. Designed for scientists and industry professionals alike, this authoritative and up-to-date volume describes how non-conventional technologies can be used to increase accessibly and bioavailability of substrates by microorganisms during fermentation, which in turn promotes microbial growth and can improve processes and productivity across the agri-food, nutraceutical, pharmaceutical, and beverage industries. The text begins by covering the conventional fermentation process, discussing cell division and growth kinetics, current technologies and developments in industrial fermentation processes, the parameters and modes of fermentation, various culture media, and the impact of culture conditions on fermentation processes. Subsequent chapters provide in-depth examination of the use of emerging technologies--such as pulsed electric fields, ultrasound, high-hydrostatic pressure, and microwave irradiation--for biomass fractionation and microbial stimulation. This authoritative resource: Explores emerging technologies that shorten fermentation time, accelerate substrate consumption, and increase microbial biomass Describes enhancing fermentation at conventional conditions by changing oxygenation, agitation, temperature, and other medium conditions Highlights the advantages of new technologies, such as reduced energy consumption and increased efficiency Discusses the integration and implementation of conventional and emerging technologies to meet consumer and industry demand Offers perspectives on the future direction of fermentation technologies and applications Fermentation Processes: Emerging and Conventional Technologies is ideal for microbiologists and bioprocess technologists in need of an up-to-date overview of the subject, and for instructors and students in courses such as bioprocess technology, microbiology, new product development, fermentation, food processing, biotechnology, and bioprocess engineering.

Acoustic Technics opens with the 19th century discovery of radiation which exceeds our human bodily perceptual experience, light beyond light, sound beyond sound and on into what today we call the electromagnetic spectrum. Claiming a second scientific revolution through imaging technologies and drawing from both instrumental sensory mediation and animal studies, Acoustic Technics follows listening in its new forms into music, echo-location, infra and ultra-sounds, medical diagnosis, surveillance, and subsurface and interplanetary domains. Synthesized sounds, sonification, in both esoteric and popular technologies such as earbuds, cellphones, television are analyzed from a postphenomenological perspective.

"MP3: The Meaning of a Format" recounts the hundred-year history of the world's most common format for recorded audio. Understanding the historical meaning of the MP3 format entails rethinking the place of digital technologies in the larger universe of twentieth-century communication history, from hearing research conducted by the telephone industry in the 1910s, through the mid-century development of perceptual coding (the technology underlying the MP3), to the format's promiscuous social life since the mid 1990s.

MP3s are products of compression, a process that removes sounds unlikely to be heard from recordings. Although media history is often characterized as a progression toward greater definition, fidelity, and truthfulness, "MP3: The Meaning of a Format" illuminates the crucial role of compression in the development of modern media and sound culture. Taking the history of compression as his point of departure, Jonathan Sterne investigates the relationships among sound, silence, sense, and noise; the commodity status of recorded sound and the economic role of piracy; and the importance of standards in the governance of our emerging media culture. He demonstrates that formats, standards, and infrastructures--and the need for content to fit inside them--are every bit as central to communication as the boxes we call "media."

El presente libro constituye una significativa contribucion a la bastante escasa bibliografia en castellano de acustica en general y ruido en particular. La obra cubre teoria y practica actualizados, con lo cual se convierte en un excelente libro de consulta y estudio, para ser usado como texto para cursos universitarios de grado y de posgrado en higiene y seguridad industrial incluso, arquitectura. El libro aborda temas tan variados como conservacion de la audicion y acustica de salas. La extensa lista de referencias, incluida la web, permite ampliar conceptos y temas. Los autores tienen muchos anos de experiencia en la ensenanza universitaria y en la practica para la solucion de problemas acusticos. El capitulo 1 introduce a los parametros y definiciones propios de control de ruido industrial, con las expresiones matematicas que permiten su calculo. En el siguiente, se ahonda en el equipamiento tipico de medicion y en la manipulacion de los datos obtenidos, incluyendo el algebra con decibeles. En el tercero se describe el sistema auditivo humano, problemas de enmascaramiento y particularidades del habla y la audicion. En el capitulo 4, se hace una exhaustiva discusion acerca de los problemas auditivos y no auditivos originados por el ruido. En el 5 se estudian los protectores auditivos con una muy buena lista de referencias.
