The article discusses dark matter and its relationship with faith. Also cited are the study of Swiss astronomer Fritz Zwicky of dark matter in the early 1930s, God's creativity and His design of the universe, God's presence on dark matter based on Ignatian spirituality, and the issue of how can a person becomes a man of science and a man of faith at the same time.

- On October 6, 2008, a small F-class asteroid 2008 TC3 was discovered by Catalina Sky Survey telescope, and exploded 20 hr later in the Earth's atmosphere at 37 km altitude. We analyzed available photometric data taken from 6 October 21:10 to 7 October 01:46 UT, and created a numerical model of a shape and rotation state of the asteroid. The asteroid was in excited rotational state. We found two approximately mirror solutions of orientation of its angular momentum vector. Rotational and precession periods are 99.20 and 97.00 s (errors of the rotational period for the two solutions are 0.03 and 0.04 s; of the precession period are 0.05 s for both solutions). The volume of the convex model and the length of the longest axis of the dynamically equivalent, equal volume ellipsoid are and , where pV is surface geometric albedo. Assuming a mean albedo value for F taxonomic class, 0.049 ± 0.010, the volume is (25 ± 10) m3 and the longest axis is (6.7 ± 0.8) m. This volume of the convex model is an upper limit on a real volume of the asteroid, which may be less by up to 20% due to concavities. [ABSTRACT FROM AUTHOR]

The 2-, 3- and 4-amino-pyridine and their protonated forms, obtained by reaction with pyridinium chloride, were investigated by 15N NMR spectroscopy. Exhaustive evidence has been found that the protonation occurs mainly on the annular nitrogen. Protonation of 4-aminopyridine by dehydrohalogenation of 1,1,2,2-tetrachloroethane (TCE) was also studied by 13C NMR spectroscopy, which indicated that the protonation occurs via the formation of adducts.

This article describes a six-year experience of psychiatric consultation in Padua Geriatric Hospital (Italy). Motivation for the request for psychiatric treatment, diagnosis, recommended treatment and compliance with it by the geriatric medical staff are reported. The authors stress the radical change in the activities of the consultants since the establishment in 1986 of a new psychogeriatric unit, probably still the only such unit in formal existence in Italy. The service offered by the team thus underwent considerable innovation, leading to substantial modifications in treatment and, especially, to a reduction in the duration of hospital stay of patients admitted to the psychogeriatric unit.
