Numerische technische Optimierung: Anwendung des Computeralgebrasystems Maxima
by Andreas Öchsner Resam MakvandiDiese Studienhilfe zu numerischen Optimierungsverfahren richtet sich an Studierende des Maschinenbaus im Grundstudium und im Hauptstudium. Optimierungsverfahren gewinnen zunehmend an Bedeutung für den Leichtbau, wo eine Gewichtsreduzierung z.B. im Automobilbau oder in der Luft- und Raumfahrtindustrie zu einem geringeren Kraftstoffverbrauch und einer entsprechenden Senkung der Betriebskosten sowie zu positiven Auswirkungen auf die Umwelt führen kann. Basierend auf dem freien Computeralgebrasystem Maxima stellen die Autoren Verfahren zur numerischen Lösung ingenieurmathematischer Probleme sowie Anwendungen aus traditionellen Lehrveranstaltungen zur Festigkeit von Werkstoffen vor. Die mechanischen Theorien konzentrieren sich auf die typischen eindimensionalen Strukturelemente, d.h. Federn, Stäbe und Euler-Bernoulli-Balken, um die Komplexität des numerischen Rahmens zu reduzieren und den resultierenden Entwurf auf eine geringe Anzahl von Variablen zu beschränken. Die Verwendung eines Computeralgebrasystems und der darin enthaltenen Funktionen, z. B. für Ableitungen oder Gleichungslösungen, ermöglicht eine stärkere Konzentration auf die Methodik der Optimierungsverfahren und nicht auf Standardverfahren.Das Buch enthält auch zahlreiche Beispiele, darunter einige, die mit Hilfe eines grafischen Ansatzes gelöst werden können, um dem Leser ein besseres Verständnis der Computerimplementierung zu vermitteln.

Nursery Practices in Oil Palm: A Manual (Techniques In Plantation Science Ser. #17)
by Brian Forster Umi Setiawati Fazrin Nur Miranti Rahmaningsih Yassier Anwar Nur D Laksono Heru Rusfiandi Eben Haeser Sembiring Avasarala Sreenivasa Subbarao Hafni ZaharaThis is a hands-on, practical guide to general and specific practices in oil palm nurseries to produce healthy, vigorous and uniform plants ready for field planting. There are two nursery stages, pre-nursery and main nursery. The pre-nursery receives both germinated seeds and tissue culture produced plantlets (ramets) which are planted in a relatively small area in which shade and humidity can be controlled. Once young plants are established they are transferred to the main nursery, potted-on and grown on to produce field-ready plants. Good nursery practices, using sustainable approaches where possible, aim to provide high quality planting materials for both commercial production and field trialling. The book covers: Nursery set up - pre-nursery and main nursery Fertilizer programmes Watering Culling Weeding Pests and diseases Pre-field genotypic screening and selection Quarantine nurseries This is an invaluable manual for commercial seed producers, nursery plant producers, commercial plantation companies and plant breeders, as well as researchers in oil palm. It is useful for those starting a career in oil palm production, and as a reference guide for managers and for training purposes.
Nutraceutical and Functional Food Processing Technology (IFST Advances in Food Science)
by Joyce I. BoyeFor several years, the food industry has been interested in identifying components in foods which have health benefits to be used in the development of functional food and nutraceutical products. Examples of these ingredients include fibre, phytosterols, peptides, proteins, isoflavones, saponins, phytic acid, probiotics, prebiotics and functional enzymes. Although much progress has been made in the identification, extraction and characterisation of these ingredients, there remains a need for ready and near-market platform technologies for processing these ingredients into marketable value-added functional food and nutraceutical products. This book looks at how these ingredients can be effectively incorporated into food systems for market, and provides practical guidelines on how challenges in specific food sectors (such as health claims and marketing) can be addressed during processing. Nutraceutical and Functional Food Processing Technology is a comprehensive overview of current and emerging trends in the formulation and manufacture of nutraceutical and functional food products. It highlights the distinctions between foods falling into the nutraceutical and functional food categories. Topics include sustainable and environmentally–friendly approaches to the production of health foods, guidelines and regulations, and methods for assessing safety and quality of nutraceutical and functional food products. Specific applications of nutraceuticals in emulsion and salad dressing food products, beverages and soft drinks, baked goods, cereals and extruded products, fermented food products are covered, as are novel food proteins and peptides, and methods for encapsulated nutraceutical ingredients and packaging. The impact of processing on the bioactivity of nutraceutical ingredients, allergen management and the processing of allergen-free foods, health claims and nutraceutical food product commercialization are also discussed. Nutraceutical and Functional Food Processing Technology is a comprehensive source of practical approaches that can be used to innovate in the nutraceutical and health food sectors. Fully up-to-date and relevant across various food sectors, the book will benefit both academia and industry personnel working in the health food and food processing sectors.
Nutraceutical and Specialty Lipids and their Co-Products
by Atif B. Awad Peter G.

The importance of essential fatty acids and fat-soluble vitamins and other minor
Nutraceutical Fatty Acids from Oleaginous Microalgae: A Human Health Perspective
by Alok Kumar Patel Leonidas MatsakasOver the past several years, extensive research has been done on the microbial production of polyunsaturated fatty acids (PUFA). Regardless, research on the oleaginous microalgae used as feedstock for biofuels production and the overall story about the production of nutraceutical fatty acids from oleaginous microalgae has been very limited. This volume provides an exclusive insight on the production of nutraceutical fatty acids from oleaginous microalgae and their role on human health. Some saturated and monounsaturated fatty acids can be synthesized by humans, whereas long-chain polyunsaturated fatty acids (PUFAs) such as α-linolenic acid and linoleic acid cannot and are deemed essential. The products of these acids, such as DHA, which is important for early visual and neurological development, are extremely important to human health. Replacing SFAs with omega-3 and omega-6 fatty acids in the diet reduce the risk of cardiovascular diseases and prevent Alzheimer's, bipolar disorder, and schizophrenia, among other benefits. The ever-rising global demand for omega-3 & 6 PUFAs, however, cannot be met solely by fish oil, due to diminishing fish stocks and pollution of marine ecosystems, which has led to increased interest in alternative sustainable sources. Vegetable oils from genetically engineered plant oilseeds and microorganisms are two potential alternatives to fish oil, even though omega-3 PUFAs are highest in the latter. Although transgenic plants present numerous advantages, their production is dependent on seasonal and climatic conditions and the availability of arable land. Moreover, there are public concerns regarding the cultivation of transgenic crops in open ecosystems. These, together with regulatory issues restrict the large-scale production of genetically modified crops. Microorganisms, however, are known natural producers of microbial oils similar to those obtained from plants and animals and a possible source of nutritionally important omega-3 & 6 PUFAs. This groundbreaking volume presents invaluable new research on essential fatty acids, their production from various oleaginous microorganisms, biochemical and metabolic engineering to improve PUFAs content in oil, extraction and purification of omega 3 fatty acids, and the current market scenario. Whether a veteran engineer or scientist using it as a reference or a professor using it as a textbook, this outstanding new volume is a must-have for any engineer or scientist working in food science.
