Book Description
ICUMSA Methods of Sugar Analysis presents the recommendations of the International Commission for Uniform Methods of Sugar Analysis (ICUMSA) that are based on thorough investigations of methods likely to prove practical and appropriate for the sugar industry. This book discusses the procedures for raw sugar polarization. Organized into two parts encompassing 21 chapters, this book begins with an overview of the various methods of determining sucrose by polarimetry, including the invertase method and the Jackson and Grill's method. This text then examines the methods of determining reducing sugars, which depends on knowing the amount of cuprous oxide precipitated from Fehling's solution. Other chapters consider the method to be applied for all beet products. This book discusses as well the principle of double sulfation that is necessary to ensure conversion of ash to sulfate. The final chapter deals with the evaluation of filter aids. This book is a valuable resource for chemists.

Book Description
Food safety and quality are key objectives for food scientists and industries all over the world. To achieve this goal, several analytical techniques (based on both destructive detection and nondestructive detection) have been proposed to fit the government regulations. The book aims to cover all the analytical aspects of the food quality and safety assessment. For this purpose, the volume describes the most relevant techniques employed for the determination of the major food components (e.g. protein, polysaccharides, lipds, vitamins, etc.), with peculiar attention to the recent development in the field. Furthermore, the evaluation of the risk associated with food consumption is performed by exploring the recent advances in the detection of the key food contaminants (e.g. biogenic amines, pesticides, toxins, etc.). Chapters tackle such subject as: GMO Analysis Methods in Food Current Analytical Techniques for the Analysis of Food Lipids Analytical Methods for the Analysis of Sweeteners in Food Analytical Methods for Pesticides Detection in Foodstuffs Food and Viral Contamination Application of Biosensors to Food Analysis

Book Description
Randomized clinical trials are the primary tool for evaluating new medical interventions. Randomization provides for a fair comparison between treatment and control groups, balancing out, on average, distributions of known and unknown factors among the participants. Unfortunately, these studies often lack a substantial percentage of data. This missing data reduces the benefit provided by the randomization and introduces potential biases in the comparison of the treatment groups. Missing data can arise for a variety of reasons, including the inability or unwillingness of participants to meet appointments for evaluation. And in some studies, some or all of data collection ceases when participants discontinue study treatment. Existing guidelines for the design and conduct of clinical trials, and the analysis of the resulting data, provide only limited advice on how to handle missing data. Thus, approaches to the analysis of data with an appreciable amount of missing values tend to be ad hoc and variable. The Prevention and Treatment of Missing Data in Clinical Trials concludes that a more principled approach to design and analysis in the presence of missing data is both needed and possible. Such an approach needs to focus on two critical elements: (1) careful design and conduct to limit the amount and impact of missing data and (2) analysis that makes full use of information on all randomized participants and is based on careful attention to the assumptions about the nature of the missing data underlying estimates of treatment effects. In addition to the highest priority recommendations, the book offers more detailed recommendations on the conduct of clinical trials and techniques for analysis of trial data.

Book Description
Data on water quality and other environmental issues are being collected at an ever-increasing rate. In the past, however, the techniques used by scientists to interpret this data have not progressed as quickly. This is a book of modern statistical methods for analysis of practical problems in water quality and water resources. The last fifteen years have seen major advances in the fields of exploratory data analysis (EDA) and robust statistical methods. The 'real-life' characteristics of environmental data tend to drive analysis towards the use of these methods. These advances are presented in a practical and relevant format. Alternate methods are compared, highlighting the strengths and weaknesses of each as applied to environmental data. Techniques for trend analysis and dealing with water below the detection limit are topics covered, which are of great interest to consultants in water-quality and hydrology, scientists in state, provincial and federal water resources, and geological survey agencies. The practising water resources scientist will find the worked examples using actual field data from case studies of environmental problems, of real value. Exercises at the end of each chapter enable the mechanics of the methodological process to be fully understood, with data sets included on diskette for easy use. The result is a book that is both up-to-date and immediately relevant to ongoing work in the environmental and water sciences.
