Описание: Provides information on the identity and purity of food additives used directly in foods or in food production. The main objectives are to identify the food additives that have been subjected to testing for safety, to ensure that additives are of the quality required for use in food, and to encourage good manufacturing practice.
Описание: The use of additive manufacturing for the direct production of finished products is becoming increasingly important. The method not only reduces the demands on industrial infrastructure, but also opens up new perspectives in terms of decentralized production and customer inclusive individualized production (customization, cyberproduction).Oriented towards the practitioner, in this book the basics of additive manufacturing are presented and the properties and special aspects of industrially available machines are discussed. From the generation of data to the forming method, the complete process chain is shown in a practical light. In particular, the following additive manufacturing technologies are discussed:Polymerization (e.g., stereolithography)Sintering and melting (e.g., laser sintering)Layer laminate method (e.g., laminated object manufacturing, LOM)Extrusion (e.g., fused deposition modeling, FDM)3D printingApplications for the production of models and prototypes (rapid prototyping), tools, tool inserts, and forms (rapid tooling) as well as end products (rapid manufacturing) are covered in detailed chapters with examples. Questions of efficiency are discussed from a strategic point of view, and also from an operational perspective.With the purchase of this book, you also receive a free personal access code to download the eBook.

Описание: "Additive Schooling in Subtractive Times" documents the unusually successful efforts of one New York City high school to educate Dominican immigrant youth, at a time when Latino immigrants constitute a growing and vulnerable population in the nation's secondary schools. Based on four and a half years of qualitative research, the book examines the schooling of teens in the Dominican Republic, the social and linguistic challenges the immigrant teens face in Washington Heights, and how Gregorio Luperon High School works with the community to respond to those challenges. The staff at Luperon see their students as emergent bilinguals and adhere to a culturally and linguistically additive approach. After offering a history of the school's formation, the authors detail the ways in which federal No Child Left Behind policies, New York State accountability measures, and New York City's educational reforms under Mayor Michael Bloomberg complicated the school's efforts. The book then describes the dynamic bilingual pedagogical approach adopted within the school to help students develop academic Spanish and English. Focusing on the lives of twenty immigrant youth, Bartlett and Garcia also show that, although the school achieves high completion rates, the graduating students nevertheless face difficult postsecondary educational and work environments that too often consign them to the ranks of the working poor.
