Laboratory Exercises for Sensory Evaluation
by Harry T. LawlessLaboratory exercises are a necessary part of science education. They enable students to better understand the principles discussed in lectures, and provide them with hands-on experience of the practical aspects of scientific research. The purpose of this book is to provide students and instructors with a time-tested set of lab exercises that illustrate the common sensory tests and/or sensory principles used in evaluation of foods, beverages and consumer products. The appendices will also include a set of simple problem sets that can be used to teach and reinforce basic statistical tests. Approximately twenty years ago the Sensory Evaluation Division of the Institute of Food Technologists sponsored the preparation of a set of exercises titled "Guidelines for Laboratory Exercises for a Course in Sensory Evaluation of Foods," edited by one of the co-authors (Heymann). This book will provide additional materials from the second author (Lawless), as well as other instructors, in a uniform format that can be easily adopted for course use. Most importantly, the lab exercises will complement the flagship textbook in the field, Sensory Evaluation of Foods: Principles and Practices, 2E, also by Lawless and Heymann and published by Springer. Possible course adoption of the main text along with the lab manual should enhance the sales of these materials.

Laboratory Models for Foodborne Infections (Food Microbiology)
by Dongyou Liu Laszlo EndrenyiResulting from ingestion of inappropriately prepared or stored foods containing pathogenic viruses, bacteria, fungi and parasites, foodborne infections have become a significant source of human morbidity and mortality worldwide in recent decades. This may be largely attributable to the remarkable popularity of convenient, ready-to-eat food products, the dramatic expansion of international food trades, and the continuing growth of immuno-suppressed population groups. Although anti-microbial treatments have played a crucial part in the control of foodborne infections in the past, the emergence and spread of anti-microbial resistance render the existing treatments ineffective. Additionally, our limited understanding of the molecular mechanisms of foodborne infections has thwarted our efforts in the development of efficacious vaccines for foodborne pathogens. Given the obvious benefits of laboratory models in foodborne disease research, a great number of experiments have been conducted toward the elucidation of host-pathogen interactions in and pathogenic mechanisms of foodborne infections. Forming part of the Food Microbiology series, Laboratory Models for Foodborne Infections presents a state-of-the-art review of laboratory models that have proven valuable in deciphering the life cycle, epidemiology, immunobiology, and other key aspects of foodborne pathogens. Written by scientists with respective expertise in foodborne pathogen research, each chapter includes a contemporary summary of a particular foodborne viral, bacterial, fungal, or parasitic infection in relation to its life cycle, epidemiology, clinical features, pathogenesis, host-pathogen interactions, and other related aspects. Besides providing a trustworthy source of information for undergraduates and postgraduates in food microbiology, Laboratory Models for Foodborne Infections offers an invaluable guide for scientists and food microbiologists with interest in exploiting laboratory models for detailed study of foodborne infections.

Laboratory Tests for Unsaturated Soils
by Eng-Choon Leong Martin WijayaThe testing of unsaturated soils requires greater care and effort than that of saturated soils. Although unsaturated soil mechanics has been embraced by geotechnical engineering, engineering practice has not yet caught up as the characterization of unsaturated soils is difficult and time-consuming, and made harder still by a lack of standards. Laboratory Tests for Unsaturated Soils collates test procedures to cover all laboratory tests for characterising unsaturated soils. It covers the background, theory, test procedures, and interpretation of test results. Each test procedure is broken down into simple stages and described in detail. The pitfalls of each test and the interpretation of the test results are explained. Test data and calculation methods are given, along with many numerical examples to illustrate the methods of interpretation and to offer the presentation of typical results. The book is especially useful for students and researchers who are new to the field and provides a practical handbook for engineering applications.
Laboratory Tests for the Assessment of Nutritional Status (Modern Nutrition Ser. #21)
by Howerde E. SauberlichProper nutrition is the single most important component of preventative health care. Heart disease, diabetes, and other ailments are all linked to dietary habits. Accurate nutritional assessment can be a matter of life or death. Laboratory Tests for the Assessment of Nutritional Status explores the expanded number of nutrients that can now be evaluated. The author makes a compelling case for the practice and advancement of this critical health care tool. Nutritional assessment identifies undernutrition, overnutrition, specific nutrition deficiencies, and imbalances. Diligent assessment determines the appropriate nutrition intervention and monitors its effects. This book is a total revision of the 1974 version of the same title co -authored by Sauberlich. Since then, remarkable progress has been made on the methodologies applicable to nutrition status assessment and to the expanded number of nutrients that can be evaluated, especially trace elements. The introduction of high-performance liquid chromatography, amperometric detectors, and other technologies has advanced nutritional assessment by leaps and bounds. Today, nutritionists can gauge the value of microminerals, trace elements, and ultratrace elements. Sauberlich's revision updates the reader to the latest and most important trends in nutrition. These laboratory methods for the assessment of nutritional status are vital for identifying individuals as well as populations with nutritional risks.
Labour Power: Virtual and Actual in Digital Production (Lecture Notes in Morphogenesis)
by Roberto CiccarelliThis book offers a critical account of Karl Marx’s dazzling theory of labour power which is also one of the most influential concepts in the history of contemporary philosophy. Labour power is the dark side of the digital revolution. Working men and women are invisible and treated like human service, flesh and blood automatons or organic extensions of a machine that produces data on its own. Automation is viewed as something magic made possible by algorithms whose life is independent of human beings.Labour power, however, has not disappeared. Without drivers, Uber cannot connect customers on its platform; without searches on its browser, Google grinds to a halt; without us, Facebook or Instagram is desert. Labour power is the dwarf hidden inside the puppet of technology that allows algorithms to be intelligent and make the biggest profits in the history of capitalism.The invisible centrality of labour power is the political enigma of our times. Today a new account of the theory of labour power is needed more than ever in order to understand the political economy of digital capitalism on new grounds. Unlike a long tradition in the history of work, labour power is not only the work or the data it produces, but a potency that does not coincide with its current commodification. The actuality of labour power does not exhaust the virtuality that can be actualised by its faculty. Even when reduced to a commodity, labour power does not exhaust the potency of its being otherwise.Immersed in the constant propaganda that boosts the latest technological inventions, we neglect the fact that this wealth is produced by us and that it could be ours precisely because it is a part of our potential to be other than what we are at present. This book is a vibrant invitation to consider the fact that we are always connected with the potency that is constantly at work in our life. If this were not the case, we would not be alive. If we do not strive to become consciously and collectively active, we will never know.
Labour Problems of Technological Change (Routledge Library Editions: Labour Economics #8)
by L. C. Hunter G. L. Reid D. BoddyFirst published in 1970. This book is concerned with the examination and assessment of the impact of changes in technology on companies in three selected industries: printing, steel and chemicals. Its main focus is on the employment and associated labour market effects of technological change; but part of the rationale for the study as a whole has been to relate these effects to the technological environment of each industry. Accordingly, a good deal of attention has been paid to the character of the innovations themselves and to their implications for the industries in general terms. This title will be of interest to students of Business Studies and Economics.
Labs of Our Own: Feminist Tinkerings with Science
by Sig / GiordanoFrom climate change to COVID-19 to reproductive justice, there has been deep political polarization around science. Labs of Our Own provides a unique entry point into these twenty-first-century science wars by focusing on our affective relationships to science. The book delves into various sites where scientists, teachers, artists, and activists claim to create more democratic access to science—from DIY biology community labs to feminist classrooms to activist science practitioners. The reader will find that these claims for and attempts at democratic sciences not only impact what counts as science and who counts as a scientist but reconfigure who is included in the proper public. Instead of arguing for a knee-jerk defense of science against right-wing attacks, Labs of Our Own builds the case for a feminist, antiracist, decolonial, queer science tinkering practice that intentionally, politically, and ethically acts to produce new challenges to the definition and boundaries of the human.

Labyrinth and Piano Key Weirs
by Sébastien Erpicum Michel Pirotton Frédéric Laugier Jean-Louis Boillat Bernard Reverchon Anton SchleissLabyrinth spillways are almost as old as dam engineering. In spite of the fact that they appear as a very good technical-economical compromise, only 0.1% of large dams are equipped with such weirs. The main reason for this is that traditional labyrinth weirs usually cannot be installed on top of concrete gravity dams as they require a large foundat
Labyrinth and Piano Key Weirs II
by Sébastien Erpicum Michel Pirotton Michael Pfister Frédéric Laugier Guy-Michel Cicero Anton J. SchleissDam engineering is currently experiencing a strong revival of labyrinth oriented weirs. Labyrinth weirs, with a repetitive constructional character and an increased specific discharge capacity, are a very good technical-economical compromise. The concept of Piano Key Weir (PKW), with alveoli developed in overhangs from a reduced support area, enabl
Labyrinth and Piano Key Weirs III: Proceedings of the 3rd International Workshop on Labyrinth and Piano Key Weirs (PKW 2017), February 22-24, 2017, Qui Nhon, Vietnam
by Sébastien Erpicum Michael Pfister Frédéric Laugier Michel Ho Ta KhanhSince the first implementation by Electricité de France on the Goulours dam (France) in 2006, the Piano Key Weir has become a more and more applied solution to increase the discharge capacity of existing spillways. In parallel, several new large dam projects have been built with such a flood control structure, usually in combination with gates. Today, more than 25 Piano Key Weirs are in operation or under construction all over the world. More than 15 years of research and development have enabled detailed investigations of the hydraulic and structural behaviour of the Piano Key Weir complex structure and have provided more and more accurate design equations. Following the proceedings of the first two workshops held in Liege (Belgium – 2011) and Paris (France – 2013), Labyrinth and Piano Key Weirs III collects the contributions presented by people with varied background, from researchers to practitioners, at the 3rd International Workshop on Labyrinth and Piano Key Weirs - PKW 2017 (22-24 February 2017, Qui Nhon, Vietnam). The papers, reviewed and accepted by an International Scientific Committee, summarize the current state-of-the-art on Piano Key Weirs from a theoretical to a practical point of view, and present most of the main projects in operation or under construction. Labyrinth and Piano Key Weirs III is thus a reference for students, practitioners and researchers interested in Dams Engineering.

Lactic Acid Bacteria: A Functional Approach
by Alejandra de Moreno de LeBlancLactic acid bacteria (LAB) are a diverse group of bacteria that comprise low GC content Gram-positive cocci or rods that produces lactic acid as the major end product of the fermentation process. Bifidobacterium genera may also be considered as a part of the LAB group for possessing some similar phenotypical characteristics despite the higher GC content. The key feature of LAB metabolism is efficient carbohydrate fermentation. This contributes to the production of several microbial metabolites that result in the improvement of flavor and texture of fermented foods, in addition to its positive impact on the human health when LAB is administered as a probiotic. The book deals with advances made in the functionalities of LAB, such as their effect on vitamin D receptor expression, impact on neurodegenerative pathologies, production of B-vitamins for food bio-enrichment, production of bacteriocins to improve gut microbiota dysbiosis, production of metabolites from polyphenols and their effects on human health, effect on reducing the immunoreaction of food allergens, as biological system using time-temperature to improve food safety, and the use of probiotics in animal feed. The book also reviews the use of LAB and probiotic technologies to develop new functional foods and functional pharmaceuticals.
Lactic Acid Bacteria: Biodiversity and Taxonomy (The\lactic Acid Bacteria Ser. #3)
by Brian J.B. Wood Wilhelm H. HolzapfelThe lactic acid bacteria (LAB) are a group of related micro-organisms that are enormously important in the food and beverage industries. Generally regarded as safe for human consumption (and, in the case of probiotics, positively beneficial to human health), the LAB have been used for centuries, and continue to be used worldwide on an industrial scale, in food fermentation processes, including yoghurt, cheeses, fermented meats and vegetables, where they ferment carbohydrates in the foods, producing lactic acid and creating an environment unsuitable for food spoilage organisms and pathogens to survive. The shelf life of the product is thereby extended, but of course these foods are also enjoyed around the world for their organoleptic qualities. They are also important to the brewing and winemaking industries, where they are often undesirable intruders but can in specific cases have desirable benefits. The LAB are also used in producing silage and other agricultural animal feeds. Clinically, they can improve the digestive health of young animals, and also have human medical applications. This book provides a much-needed and comprehensive account of the current knowledge of the lactic acid bacteria, covering the taxonomy and relevant biochemistry, physiology and molecular biology of these scientifically and commercially important micro-organisms. It is directed to bringing together the current understanding concerning the organisms’ remarkable diversity within a seemingly rather constrained compass. The genera now identified as proper members of the LAB are treated in dedicated chapters, and the species properly recognized as members of each genus are listed with detailed descriptions of their principal characteristics. Each genus and species is described using a standardized format, and the relative importance of each species in food, agricultural and medical applications is assessed. In addition, certain other bacterial groups (such as Bifidobacterium) often associated with the LAB are given in-depth coverage. The book will also contribute to a better understanding and appreciation of the role of LAB in the various ecological ecosystems and niches that they occupy. In summary, this volume gathers together information designed to enable the organisms’ fullest industrial, nutritional and medical applications. Lactic Acid Bacteria: Biodiversity and Taxonomy is an essential reference for research scientists, biochemists and microbiologists working in the food and fermentation industries and in research institutions. Advanced students of food science and technology will also find it an indispensable guide to the subject.
