Book Description
Atlas and Tables for Emission Spectrographic Analysis of Rare Earth Elements focuses on the analysis of rare earths with the Zeiss Q 24 spectrograph or with instruments of similar dispersion. The book first offers information on the division of the spectra of rare earth elements and Sc and Y into three groups. The spectra of Ce, Pr, Nd, Gd, Tb, Dy, Ho, and Er have lines that, however, do not form characteristic line groups. The text underscores that in preparing the Atlas, the spectral pure-grade rare earth oxides sold by the Johnson & Matthey Co. were considered. Through the help of their spectra, the usable analysis lines and the wavelength values of the interfering spectral lines are created. The operating and photographic conditions are tabulated. The book stresses that for each rare earth, the analysis lines are provided in order of decreasing wavelength. The number located in the lower left corner for each analysis line indicates its relative intensity. The fifteen columns contain the interfering lines of other rare earths and of Sc and Y. The interfering lines are created through the use of the double projector of the Optica Milano Co. and the Gatterer Spectrum. The text is a great source of information for readers wanting to analyze rare earths with the Zeiss Q 24 spectrograph or with instruments of similar dispersion.

Book Description
Water Resources in the Mediterranean Region summarizes and collates scientific developments around water resources in the Mediterranean socio-economic environment through a multidisciplinary framework synthesizing hydrology, hydrogeology, climate, bioclimatology, economics, and geography. As such, it provides essential information for any reader looking to learn more about the Mediterranean which is experiencing the impact of climate change and concurrent complex issues of anthropogenic effects, especially in agriculture and other resource uses. Water Resources in the Mediterranean Region covers different challenges in the issue of the evolution of water resources in the Mediterranean. It is intended for PhD students, research scientists, and managers interested in new solutions and approaches for water management and in the forecast of future water dynamics. Offers multidisciplinary content providing global visions of the challenges faced in the Mediterranean region Presents fundamental and operational studies, providing the reader with information on how to implement these actions and results themselves Written in a pedagogical manner, allowing for ease of reading for both researchers and water managers
