    Notes: Polarised two-photon excitation (TPE) spectroscopy is a powerful technique for probing the energy levels of f-block elements at high symmetry sites because most pure electronic transitions are allowed by the selection rules. TPE in a magnetic field provides additional information, through the resolution of Zeeman components, evaluation of g-values, and the appearance of intensity in forbidden transitions. Here we present the selection rules and polarisation dependence for two-photon absorption at cubic sites, in a magnetic field. Polarised TPE spectra for the elpasolites Cs2NaTbX6 (X=F, Cl) are in excellent agreement with theory. The sensitivity of the second order Zeeman effect to the orientation of a cubic crystal relative to the magnetic field is illustrated, together with successful modelling of the Zeeman interaction for a number of multiplets. © 1997 American Institute of Physics.

    Notes: The origin of spurious and irreproducible signals in the measurement of the hyper-Rayleigh scattering (HRS) of solutions is investigated. A new cell design, coupled with continuous solution filtration through a 20 nm filter, is shown to improve the reproducibility of the measurement to ±5%. A transverse cell dimension of ∼2 mm reduces absorption of the second harmonic. A simple monochromaticity test is used to identify luminescence, and we recommend that it is made routinely. Scattering from the [Ru(bipy)3]2+ cation, attributed to HRS by Zyss et al. [Chem. Phys. Lett. 206, 409 (1993)], appears to be largely due to two-photon excited luminescence. The reliability of calibration procedures is examined, and some revised hyperpolarizabilities are reported. © 1996 American Institute of Physics.

    Notes: Conclusion In conclusion, a word about the spiritual aspects of the ministry to the heart patient. All members of the hospital bly, the family coming to the hospital team minister in one way or another. The chaplain has a unique place on this team. He, too, can escape from a ministry by use of “religious injections”. There are times for prayer and sacraments, and only the individual chaplain can finally decide the appropriate if, where, and when. As the chaplain explores the meaning of the hospital experience with the patient—the patient's feelings about life, death, experiences, and goals; giving and understanding where it is needed; aiding in the healing of the whole person—surely this ministry is a reflection of his motivation and is in part an attempt to realize in another the wholeness and fullness of man. It is not the physical therapy of the doctor; it is not the psychotherapy of the psychiatrist. It is the spiritual therapy of the chaplain.

    Notes: Abstract. The management of 38 consecutive patients with differentiated thyroid carcinoma in the period 1991–1996, who each received at least one therapy dose of iodine-131, was reviewed, looking in particular at those in whom anterior mediastinal uptake was demonstrated on scans taken 3 and 7 days post-therapy. Such activity was noted in ten patients. On the basis of clinical follow-up, thyroglobulin measurement and radiological and other scintigraphic imaging, in nine of the ten patients the anterior mediastinal activity was attributed to physiological thymic uptake. Of those nine, all were under 50 years of age; seven were considered disease free, one had residual disease in the neck and one had distant metastases. Physiological uptake by the thymus was more prominent on the 7-day scans and in patients with low tumour volumes. For appropriate patient management it is essential to recognise that physiological uptake of 131I by the thymus in patients under 50 years of age is a potential cause of false-positive therapy scans.
