Book Description
"Esta investigación presenta una continuación al trabajo realizado por el Dr. José Ángel Manrique Valadez, inventor del diseño del generador de un ciclo de refrigeración por absorción de tres toneladas (U.S. Patent 5,666,818), para que dicho ciclo pudiera operar con energía térmica proveniente de un arreglo de colectores solares. Este sistema se encuentra actualmente en operación en la Casa Solar del Instituto Tecnológico y de Estudios Superiores de Monterrey, Campus Monterrey. Se utilizo el paquete computacional COMSOL Multiphysics, para modelar y realizar simulaciones computacionales en estado estable de los fenómenos de transferencia de calor y mecánica de fluidos que tiene lugar durante la operación del generador, constituyendo esto el primer estudio numérico computacional para aplicación de este dispositivo".

Book Description
Food engineering has become increasingly important in the food industry over the years, as food engineers play a key role in developing new food products and improved manufacturing processes. While other textbooks have covered some aspects of this emerging field, this is the first applications-oriented handbook to cover food engineering processes and manufacturing techniques. A major portion of Handbook of Food Engineering Practice is devoted to defining and explaining essential food operations such as pumping systems, food preservation, and sterilization, as well as freezing and drying. Membranes and evaporator systems and packaging materials and their properties are examined as well. The handbook provides information on how to design accelerated storage studies and determine the temperature tolerance of foods, both of which are important in predicting shelf life. The book also examines the importance of physical and rheological properties of foods, with a special look at the rheology of dough and the design of processing systems for the manufacture of dough. The final third of the book provides useful supporting material that applies to all of the previously discussed unit operations, including cost/profit analysis methods, simulation procedures, sanitary guidelines, and process controller design. The book also includes a survey of food chemistry, a critical area of science for food engineers.

Book Description
Polymers are permeable, whilst ceramics, glasses and metals are gener ally impermeable. This may seem a disadvantage in that polymeric containers may allow loss or contamination of their contents and aggressive substances such as water will diffuse into polymeric struc tures such as adhesive joints or fibre-reinforced composites and cause weakening. However, in some cases permeability is an advantage, and one particular area where this is so is in the use of polymers in drug delivery systems. Also, without permeable polymers, we would not enjoy the wide range of dyed fabrics used in clothing and furnishing. The fundamental reason for the permeability of polymers is their relatively high level of molecular motion, a factor which also leads to their high levels of creep in comparison with ceramics, glasses and metals. The aim of this volume is to examine some timely applied aspects of polymer permeability. In the first chapter basic issues in the mathema tics of diffusion are introduced, and this is followed by two chapters where the fundamental aspects of diffusion in polymers are presented. The following chapters, then, each examine some area of applied science where permeability is a key issue. Each chapter is reasonably self-contained and intended to be informative without frequent outside reference. This inevitably leads to some repetition, but it is hoped that this is not excessive.

Book Description
Trends in Food Engineering presents a wide vision of food engineering, with an emphasis on topics vital to the food industry today. The first section deals with physical and sensory properties of food. The emphasis in these chapters is on structure-function relationships, food rheology, and the correlations between physicochemical and sensory data. The second section, on advances in food processing, includes recent developments in minimal preservation and thermal and nonthermal processing of foods. The book concludes with current topics in food engineering, including applied biotechnology, food additives, and functional properties of proteins.

Book Description
For all courses in soils and foundations, geotechnical engineering, soil mechanics, and foundation engineering. Ideal for beginners, Soils and Foundations presents all essential aspects of soils and foundations in as simple and direct a manner as possible. Filled with worked examples, step-by-step solutions, and hands-on practice problems, it emphasises design and practical applications supported by basic theory. Throughout, the authors promote learning through the extensive use of diagrams, charts, and illustrations. Coverage includes: engineering properties of soils: soil exploration, compaction, stabilisation, and consolidation; water in soil; subsurface stresses; settlement of structures; shear strength; shallow and deep foundations; lateral earth pressure; retaining structures, and stability analysis of slopes. This edition's new coverage includes Pressuremeter and Dilatometer tests, water flow characterisation with Bernoulli's Theorem, dewatering, uplift pressure on dams, and subsurface stresses caused by overlying soil masses.
