Moral Good, the Beatific Vision, and God’s Kingdom Writings by Germain Grisez and Peter Ryan, S.J.. Edited by Peter J. Weigel
For close to half a century, the work of Germain Grisez has been highly influential, and his writings continue to receive considerable attention from philosophers and theologians of diverse viewpoints. His co-author for this work is the professor and noted moral theologian Fr. Peter Ryan, S.J., currently the executive director of the Secretariat of Doctrine and Canonical Affairs of the United States Conference of Catholic Bishops (USCCB). These two eminent scholars explore fundamental questions about Christian eschatology, moral theory, the purpose of human life, and the promise of human fulfilment. The authors examine Christian teaching on the final destiny of persons, investigating the meaning of God's kingdom, the hope of the beatific vision, and the centrality of moral goodness and divine grace in one's final end. This work is an ideal source for students, scholars, ministers and lay persons interested in basic questions of Christian theology, the philosophy of religion, ethical theory, and Catholic doctrin

Implementing light elements detection and quantification in aluminosilicate materials using a Low-Z total-reflection X-ray fluorescence spectrometer
Total-reflection X-ray fluorescence (TXRF) is a well-established atomic spectroscopy technique used for the elemental characterization of different kinds of matrixes in several fields. Previous works demonstrated its applicability for the elemental quantification of aluminosilicates and, in particular, clays. However, one of the limits of the previously developed methods was the detection and quantification of light elements, in particular for those elements with an atomic number (Z) below 13 (Al). In the present work a new TXRF-based analytical method for the quantification of light elements in aluminosilicate materials is described, using an in-house built Low-Z TXRF spectrometer equipped with a Cr source, a multilayer monochromator, an SDD detector equipped with an ultrathin Si3N4 window and a vacuum chamber. Samples were prepared as simple slurries (dispersing 50 mg of powder into 2.5 mL of 1%-Triton X-100 water solution and adding Ag as internal standard) and 10 mu L were deposited onto a quartz carrier and dried before the analysis. Light elements such as F, Na and Mg were quantified with a limit of detection of 682, 260 and 133 mg/kg, respectively. Carbon and oxygen could also be detected. The new method allowed a complete analysis of major elements in aluminosilicates from F to Fe. The method showed a good accuracy in the range of 80-120% and the results agreed with the data obtained with a commercial TXRF spectrometer (for elements >13) and WDXRF, employed as reference methods. Despite a lower precision in respect to WDXRF, in some samples the quantification of F was possible only by using the Low-Z TXRF spectrometer. Finally, the method demonstrated to be suitable for the analysis of aluminosilicates, in particular when low amounts of sample (few milligrams) are available

Parameter study of self-absorption effects in Total Reflection X-ray Fluorescence–X-ray Absorption Near Edge Structure analysis of arsenic
Total reflection X-ray Fluorescence (TXRF) analysis in combination with X-ray Absorption Near Edge
Structure (XANES) analysis is a powerful method to perform chemical speciation studies at trace element
levels. However, when measuring samples with higher concentrations and in particular standards, damping
of the oscillations is observed. In this study the influence of self-absorption effects on TXRF–XANES
measurements was investigated by comparing measurements with theoretical calculations. As(V) standard
solutions were prepared at various concentrations and dried on flat substrates. The measurements showed a
correlation between the damping of the oscillations and the As mass deposited. A Monte-Carlo simulation
was developed using data of the samples shapes obtained from confocal white light microscopy. The results
showed good agreement with the measurements; they confirmed that the key parameters are the density of
the investigated atom in the dried residues and the shape of the residue, parameters that combined define
the total mass crossed by a certain portion of the incident beam. The study presents a simple approach for
an a priori evaluation of the self-absorption in TXRF X-ray absorption studies. The consequences for Extended
X-ray Absorption Fine Structure (EXAFS) and XANES measurements under grazing incidence conditions are
discussed, leading to the conclusion that the damping of the oscillations seems to make EXAFS of
concentrated samples non feasible. For XANES “fingerprint” analysis samples should be prepared with a
deposited mass and sample shape leading to an acceptable absorption for the actual investigation
