Notizen: Summary In a class experiment in clinical pharmacology, 12 pharmacy students demonstrated on themselves the anticholinergic effects of benzilonium bromide. Changes in salivary volume and heart rate showed differences in duration of action between two formulations of the drug.

Notizen: Abstract In this paper, the Hilbert-space analogue of a result of Huang, that all the methods in the Huang class generate the same sequence of points when applied to a quadratic functional with exact linear searches, is established. The convergence of a class of direct prediction methods based on some work of Dixon is then proved, and these methods are then applied to some control problems. Their performance is found to be comparable with methods involving exact linear searches.

Notizen: Abstract In this paper, the convergence of variable-metric methods without line searches (direct prediction methods) applied to quadratic functionals on a Hilbert space is established. The methods are then applied to certain control problems with both free endpoints and fixed endpoints. Computational results are reported and compared with earlier results. The methods discussed here are found to compare favorably with earlier methods involving line searches and with other direct prediction quasi-Newton methods.

Notizen: Examination of the phosphorescence emission form polypropylene shows the lifetime of the emission to be unaffected by a hydroxybenzophenone light stabilizer but significantly shorted by a diamagnetic Ni(II) chelate stabilizer.

Notizen: An improved gas comparison pycnometer has been developed, based on precise differential pressure measurements coupled with a sample volume compensator. Using helium gas, volumes of solid and powdered explosives can be measured to a precision approaching one part in lo4. Coupled with a precise mass measurement, these volumes allow densities with an uncertainty of ∼± 0.002 g/ml to be inferred. Measurements performed on various explosives have allowed assessment of the purity and homogeneity of individual samples. It is also possible to infer void percentage or porosity in pressed explosive pellets.
