New Releases by Ian WILLIAMS

This publication illustrates the variety and unpredicatability of conditions encountered by primary care physicians. Some of the topics covered include cardiovascular disease symptoms, nail disorders, skin conditions, infectious diseases, carcinoms and orthopaedics.

"The structures, energies and reactivities of nitrogen containing heterocyclic compounds are studied using computational methods. A method to calculate azole, azine and benzoazole heats of formation using ab initio total energies and isolobal reaction schemes is developed, and gives heats of formation to within 0-4 kcaVmol of experiment. Systematic errors in semi-empirical MNDO, AMI and PM3 heats of formation of azoles, azines and benzoazoles are discussed, and correction terms suggested. Pentazole, pentazine, hexazine, pyrazepine, indazine, punne, azolotriazine and diazoazole heats of formation are then predicted. Isocyanate equilibrium geometries calculated with semi-empirical and ab initio methods are compared to experiment. [...] A simple atom-atom potential method is used to model the stability and dynamics of small endohedral gas molecules inside fullerene cages. The results are shown to compare qualitatively with available ab initio results. The problem of electron correlation is briefly addressed, and relationships between Configuration Interaction (CI) and Natural Spin Orbitals (NSOs) are discussed." --
