Download or read book A Numerical Investigation of Metabolic Reductive Dechlorination in DNAPL Source Zones written by John Anthony Christ and published by . This book was released on 2005 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the most intractable environmental remediation problems are those involving the release of dense non-aqueous phase liquids (DNAPLs), such as chlorinated solvents, to the subsurface. Research efforts have focused on the use of numerical models to investigate reductions in contaminant concentrations due to partial mass removal and improvements in the performance of complementary source zone remediation technologies. Previous numerical investigations, however, have been limited to two-dimensional systems. Furthermore, a lack of models capable of simulating the most promising complementary technology, metabolic reductive dechlorination, has limited its application. This work developed and applied compositional multiphase numerical simulators to examine the influence of dimensionality (two-dimensions versus three-dimensions) on DNAPL source zone simulations and to investigate the benefits of stimulating metabolic reductive dechlorination at a chlorinated ethene-DNAPL contaminated site. Results from the dimensionality investigation showed that the simulation of DNAPL migration, entrapment, and dissolution in two dimensions provided reasonable approximations to the behavior simulated in three dimensions. Commonly employed saturation distribution and mass recovery metrics were approximately equivalent. Flux- averaged concentrations simulated in two dimensions, however, tended to be three to four times higher than those simulated in three dimensions. This difference was attributed to dilution at the down gradient boundary. An alternative metric, mass flux reduction, however, yielded better agreement.
Download or read book Food Safety Culture written by Frank Yiannas and published by Springer Science & Business Media. This book was released on 2008-12-10 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food safety awareness is at an all time high, new and emerging threats to the food supply are being recognized, and consumers are eating more and more meals prepared outside of the home. Accordingly, retail and foodservice establishments, as well as food producers at all levels of the food production chain, have a growing responsibility to ensure that proper food safety and sanitation practices are followed, thereby, safeguarding the health of their guests and customers. Achieving food safety success in this changing environment requires going beyond traditional training, testing, and inspectional approaches to managing risks. It requires a better understanding of organizational culture and the human dimensions of food safety. To improve the food safety performance of a retail or foodservice establishment, an organization with thousands of employees, or a local community, you must change the way people do things. You must change their behavior. In fact, simply put, food safety equals behavior. When viewed from these lenses, one of the most common contributing causes of food borne disease is unsafe behavior (such as improper hand washing, cross-contamination, or undercooking food). Thus, to improve food safety, we need to better integrate food science with behavioral science and use a systems-based approach to managing food safety risk. The importance of organizational culture, human behavior, and systems thinking is well documented in the occupational safety and health fields. However, significant contributions to the scientific literature on these topics are noticeably absent in the field of food safety.
Download or read book Retail Food Safety written by Jeffrey Farber and published by Springer. This book was released on 2014-10-07 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Currently, there is no one book or textbook that covers all aspects of retail food safety. It is becoming apparent that a number of issues relating to retail food safety have come to the forefront in some jurisdictions of late. For example, a recent USDA risk assessment has pointed out that issues occurring at USA retail appear to be critical in terms of contamination of deli-meat. As well, a large listeriosis outbreak in Quebec pointed to retail cross-contamination as a key issue. In terms of sanitation, a number of advances have been made, but these have not all been synthesized together in one chapter, with a focus on retail. In addition, the whole area of private standards and the Global Food Safety Initiative (GFSI) have come to the forefront of late and these as well will be explored in great detail. Other aspects related to the safety of important food commodities such as seafood, meat, produce and dairy will also be discussed and salient areas addressed.

Download or read book Foodborne Pathogens written by Joshua B. Gurtler and published by Springer. This book was released on 2017-06-14 with total page 653 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foodborne illnesses continue to be a major public health concern. All members of a particular bacterial genera (e.g., Salmonella, Campylobacter) or species (e.g., Listeria monocytogenes, Cronobacter sakazakii) are often treated by public health and regulatory agencies as being equally pathogenic; however, this is not necessarily true and is an overly conservative approach to ensuring the safety of foods. Even within species, virulence factors vary to the point that some isolates may be highly virulent, whereas others may rarely, if ever, cause disease in humans. Hence, many food safety scientists have concluded that a more appropriate characterization of bacterial isolates for public health purposes could be by virotyping, i.e., typing food-associated bacteria on the basis of their virulence factors. The book is divided into two sections. Section I, “Foodborne Pathogens and Virulence Factors,” hones in on specific virulence factors of foodborne pathogens and the role they play in regulatory requirements, recalls, and foodborne illness. The oft-held paradigm that all pathogenic strains are equally virulent is untrue. Thus, we will examine variability in virulence between strains such as Listeria, Salmonella, Campylobacter, Cronobacter, etc. This section also examines known factors capable of inducing greater virulence in foodborne pathogens. Section II, “Foodborne Pathogens, Host Susceptibility, and Infectious Dose” , covers the ability of a pathogen to invade a human host based on numerous extraneous factors relative to the host and the environment. Some of these factors include host age, immune status, genetic makeup, infectious dose, food composition and probiotics. Readers of this book will come away with a better understanding of foodborne bacterial pathogen virulence factors and pathogenicity, and host factors that predict the severity of disease in humans.

Download or read book Thermodynamics and Kinetics of Phase Transformations Volume 398 written by James S. Im and published by . This book was released on 1996-09-10 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emphasis of this book is on the quantitative analysis of transformation kinetics, integrated with thermodynamics. Solidification is a success story for quantitative kinetics analysis. The work reported concentrates on phase selection under extreme processing - large undercooling or ultrarapid quenching - of the liquid. Theoretical treatments are concerned mainly with the analysis of morphological instabilities during directional solidification at more conventional rates. The coverage of particle-beam effects is distinguished by the materials studied: alkali halides, minerals, semiconductors and metals. The thermodynamics of interfaces are a particular focus, especially in connection with the solid-state formation of amorphous phases. A highlight of the book is the coverage of the Johnson-Mehl-Avrami-Kolmogorov analysis of overall transformation kinetics. This venerable treatment is revisited and new insights and limitations are explored. Topics include: transformations in undercooled liquids; directional solidification; particle beam-induced transformations; interfaces - thermodynamics and reactions; amorphous materials - structure and transformations; solid-state transformations and ordering and phase separation.

Book excerpt: ‘KUMBA AFRICA’, is a compilation of African Short Stories written as fiction by Sampson Ejike Odum, nostalgically taking our memory back several thousands of years ago in Africa, reminding us about our past heritage. It digs deep into the traditional life style of the Africans of old, their beliefs, their leadership, their courage, their culture, their wars, their defeat and their victories long before the emergence of the white man on the soil of Africa. As a talented writer of rich resource and superior creativity, armed with in-depth knowledge of different cultures and traditions in Africa, the Author throws light on the rich cultural heritage of the people of Africa when civilization was yet unknown to the people. The book reminds the readers that the Africans of old kept their pride and still enjoyed their own lives. They celebrated victories when wars were won, enjoyed their New yam festivals and villages engaged themselves in seasonal wrestling contest etc; Early morning during harmattan season, they gathered firewood and made fire inside their small huts to hit up their bodies from the chilling cold of the harmattan. That was the Africa of old we will always remember. In Africa today, the story have changed. The people now enjoy civilized cultures made possible by the influence of the white man through his scientific and technological process. Yet there are some uncivilized places in Africa whose people haven’t tested or felt the impact of civilization. These people still maintain their ancient traditions and culture. In everything, we believe that days when people paraded barefooted in Africa to the swarmp to tap palm wine and fetch firewood from there farms are almost fading away. The huts are now gradually been replaced with houses built of blocks and beautiful roofs. Thanks to modern civilization. Donkeys and camels are no longer used for carrying heavy loads for merchants. They are now been replaced by heavy trucks and lorries. African traditional methods of healing are now been substituted by hospitals. In all these, I will always love and remember Africa, the home of my birth and must respect her cultures and traditions as an AFRICAN AUTHOR.
