For a calculation of divergent fermion string amplitudes a regularization procedure invariant under the supermodular group is constructed. By this procedure superstring amplitudes of an arbitrary genus are calculated using both partition functions and superfield vacuum correlators computed early. A finiteness of superstring amplitudes and related topics are discussed. E-mail address: danilov@th...

The setting up and priming of an intravenous infusion is a common nursing procedure. However, it is associated with certain complications, for example infection. This article describes a step-by-step guide to the equipment required, correct preparation of the patient and the procedure. It also provides readers with calculation of drip-rate formulae.

Advancements in the field of Computer-Assisted Structure Elucidation (CASE) of Natural Products achieved in the past five years are discussed. This process starts with a dereplication procedure, supported by structure-spectrum databases. Both commercial and free products are available to support the procedure. A number of new programs,as well as advancements in existing ones, are presented. Fin...

A singular value decomposition based harmonic inversion signal processing scheme is applied to the semiclassical initial value representation (IVR) calculation of molecular vibrational states. Relative to usual IVR procedure of Fourier analysis of a signal made from the Monte Carlo evaluation of the phase space integral in which many trajectories are needed, the new procedure obtains acceptable...
