 Paul Fouracre, "Eternal light and earthly concerns: Belief and the shaping of medieval society " English | ISBN: 1784993018 | 2021 | 288 pages | EPUB | 853 KB In early Christianity it was established that every church should have a light burning on the altar at all times. In this unique study, Eternal light and earthly concerns, looks at the material and social consequences of maintaining these 'eternal' lights. It investigates how the cost of lighting was met across western Europe throughout the whole of the Middle Ages, revealing the social organisation that was built up around maintaining the lights in the belief that burning them reduced the time spent in Purgatory. When that belief collapsed in the Reformation the eternal lights were summarily extinguished. The history of the lights thus offers not only a new account of change in medieval Europe, but also a sustained examination of the relationship between materiality and belief.  Essential Oils As Antimicrobial Agents in Food Preservation English | 2023 | ISBN: 1032348747 | 315 Pages | PDF (True) | 13 MB The existing methods to prolong the shelf life of food mainly include adding preservatives, irradiation, cold storage, heat treatment and controlled atmosphere storage. But with disadvantages in irradiation, cold storage, heat treatment and controlled atmosphere storage, chemical synthetic preservatives are still the main means to control food corruption.

R. A. Martins, "Engineering Design Optimization" English | ISBN: 1108833411 | 2022 | 650 pages | PDF | 14 MB Based on course-tested material, this rigorous yet accessible graduate textbook covers both fundamental and advanced optimization theory and algorithms. It covers a wide range of numerical methods and topics, including both gradient-based and gradient-free algorithms, multidisciplinary design optimization, and uncertainty, with instruction on how to determine which algorithm should be used for a given application. It also provides an overview of models and how to prepare them for use with numerical optimization, including derivative computation. Over 400 high-quality visualizations and numerous examples facilitate understanding of the theory, and practical tips address common issues encountered in practical engineering design optimization and how to address them. Numerous end-of-chapter homework problems, progressing in difficulty, help put knowledge into practice. Accompanied online by a solutions manual for instructors and source code for problems, this is ideal for a one- or two-semester graduate course on optimization in aerospace, civil, mechanical, electrical, and chemical engineering departments.
