THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

Ecotoxicological aspects related to the presence of pharmaceuticals in the aquatic environment

Background: In recent years, there has been a major focus on analyzing drug substances from dried µl volumes of biological fluids, commonly known as dried matrix spotting Results: 10 µl oral fluid, spiked with five basic drugs, was collected and stored as dried spots on alginate and chitosan foam, and subsequently dissolved; the drugs were thereafter isolated with electromembrane extraction and analyzed by LC–MS The correlation coefficients were above 09885 for all drugs in the range 25–1000 ng/ml The reported RSD values were below 15% Conclusion: Storage of oral fluid as dried spots on alginate and chitosan foam have been investigated for the first time The extract obtained after electromembrane extraction was directly compatible with LC–MS, and apparently free from coextracted matrix components

Storage of oral fluid as dried spots on alginate and chitosan foam - a new concept for oral fluid collection.

Separation of fat-soluble vitamins by hydrophobic interaction electrokinetic chromatography with tetradecylammonium ions as pseudostationary phase

An atomic emission detector has been evaluated for the estimation of C:H and C:N ratios of compounds eluted in gas chromatography. When C:H and C:N ratios were estimated using external reference compounds, the greatest accuracy was obtained when the quantity of the reference compound was similar to that of the analyte of interest.



The accuracy of the C:H and C:N ratios determined was also affected by the molecular structure of the reference compound. C:H ratios of the greatest accuracy were obtained by using reference compounds having structures similar or close to those of the compound of interest; this was not always so for C:N ratios.
