Physical Chemistry, A Series of Monographs: Active Nitrogen presents the methods by which active nitrogen may be produced. This book is composed of five chapters that evaluate the energy content, molecular spectrum, and the emission of active nitrogen. Some of the topics covered in the book are the summary of light-emitting systems of active nitrogen; analysis of Long-Lived Lewis-Rayleigh Afterglow theory and Ionic theory of Mitra; reactions followed by induced light emission; and characteristics of homogeneous recombination. Other chapters deal with the analysis of metastable molecule theories and the mechanisms for reactions of active nitrogen involving direct N(4S) attack. The discussion then shifts to the rate constants for reactions induced by direct N(4S) attack. The evaluation of the Short-Lived Energetic Afterglow theory is presented. The final chapter is devoted to the examination of emission from molecular species with electronic energy levels below 9.76 eV. The book can provide useful information to physicists, students, and researchers.

This book presents WHO guidelines for the protection of public health from risks due to a number of chemicals commonly present in indoor air. The substances considered in this review, i.e. benzene, carbon monoxide, formaldehyde, naphthalene, nitrogen dioxide, polycyclic aromatic hydrocarbons (especially benzo[a]pyrene), radon, trichloroethylene and tetrachloroethylene, have indoor sources, are known in respect of their hazardousness to health and are often found indoors in concentrations of health concern. The guidelines are targeted at public health professionals involved in preventing health risks of environmental exposures, as well as specialists and authorities involved in the design and use of buildings, indoor materials and products. They provide a scientific basis for legally enforceable standards.

A method is presented for calculating lift distributions for unswept wings with flaps or ailerons using nonlinear section lift data. This method is based upon lifting-line theory and is an extension to the method described by NACA Report 865. Simplified computing forms containing detailed examples are given for both symmetrical and asymmetrical lift distributions. A few comparisons of experimental and calculated characteristics are also presented.
