Volumes in this widely revered series present comprehensive reviews of drug substances and additional materials, with critical review chapters that summarize information related to the characterization of drug substances and excipients. This organizational structure meets the needs of the pharmaceutical community and allows for the development of a timely vehicle for publishing review materials on this topic. The scope of the Profiles series encompasses review articles and database compilations that fall within one of the following six broad categories: Physical profiles of drug substances and excipients; Analytical profiles of drug substances and excipients; Drug metabolism and pharmacokine...
Agriculture as a sector; Factor growth and allocation; Technology; Static and dynamic behavior.
This is the 41st volume in the series Advances in Chromatography. The papers in this volume: take advantage of the properties of electroosmotic flow to explore capillary electrochromatography as an alternative to HPLC for nonvolatile analytes; analyze advances in biomembrane chromatography using reverse-phase HPLC for protein purification and biophysical studies of peptides and proteins at lipid-like surfaces; focus on trace metal determination and speciation performed by liquid chromatography methods; and more.
Today, among the various chiral discrimination methods, chromatography and capillary electrophoresis techniques have become powerful tools in environmental analysis. Therefore, there is a need to describe the art of the determination of the chiral pollutants in the environmental matrices. This book provides the complete information on the types of the chiral pollutants, their toxicities and methods of determination by chromatography and capillary electrophoresis.
Quality measurement, control, and improvement in combinatorial chemistry Combinatorial chemistry has developed rapidly in the past decade, with great advances made by scientists working on analysis and purification of a large number of compounds and the analysis of polymer-bound compounds. However, formidable challenges lie ahead of today's researcher. For example, high-throughput analysis and purification technologies must be further developed to ensure combinatorial libraries are "purifiable," and "drugable." To this end, Analysis and Purification Methods in Combinatorial Chemistry describes various analytical techniques and systems for the development, validation, quality control, purific...
The New York City Department of Education asked RAND to conduct an independent longitudinal evaluation of its 5th-grade promotion policy. The findings of that study, conducted between March 2006 and August 2009, provide a comprehensive view of the policy's implementation and its impact on student outcomes, particularly for students at risk of retention and those who were retained in grade.
"Despite recent progress in reading achievement among children in primary grades, many children are not moving beyond basic decoding skills to fluency and comprehension as they go on to higher grades. To address this problem, many policymakers suggest that reading coaches - master teachers who offer ongoing on-site instructional support for teachers - can improve teachers' practice and students' literacy skills. RAND researchers evaluated the middle school reading coach program in Florida to answer these questions: How is the program being implemented by the state, districts, schools, and individual coaches? What is the impact of coaching on teachers' practice and students' achievement in reading and mathematics? What features of reading coach models and practices are associated with better outcomes?"--BOOK JACKET.
Capillary electrochromatography (CEC) is a new and exciting hybrid separation technique that seeks to exploit the combined advantages of both capillary electrophoresis (high efficiencies) and HPLC (mobile and stationary phase selectivity). It is a technique with tremendous potential, especially in the pharmaceutical and biomedical fields. This is the first book to be devoted to the topic and presents reviews by the world leaders in the field on the theory and development of the technique and current and potential future applications. Capillary Electrochromatography provides an excellent introduction to the field for graduates and professionals in industry and academia with an interest in separation science.
Capillary Electrophoresis (CE) is a powerful analytical technique used to separate compounds and is increasingly being used in routine analytical laboratories. Analysis and Detection by Capillary Electrophoresis presents developments enabling the enhancement of the detection sensitivity in CE, including the different strategies used to achieve sensitivity requirements. It describes techniques allowing sample preconcentration and sensitive continuous detection systems and looks at recent developments such as chiral analysis in CE and electrochemical detection in microchips. UV-Vis absorbance detection, as the most widely used detection system in CE, is also presented. Analysis and Detection b...
