The title furan-ocoumarin, C14H12O4 [systematic name: 9-hy-droxy-2-(prop-1-en-2-yl)-2,3-di-hydro-7H-furo[3,2-g]chromen-7-one], crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The two mol-ecules differ essentially in the orientation of the propenyl group with respect to the mean plane of the furan-ocoumarin moiety; the O-C(H)-C=C torsion angle is 122.2 (7)° in mol-...

change was a 4% decrease in 1982. When resources are limited, as they have been in recent years, NCI receives many sugges tions about how these resources should be allocated. The newly instituted corporate management system described in a previous letter to Cancer Research (1) allowed the NCI, with the many suggestions of its advisory boards, to adjust rapidly to the budget reductions in 1982 b...

Ranging from customer service to board presentations, tablets increasingly penetrate the customer advisory process. Past research on mobile banking solutions focused on their potentials in an educational setting, on the advisory process, or on the design of a tablet solution in the retail banking sector. However, little research exists on the impact of tablets on the advisory process in p...

Both advisory systems and expert systems provide expertise to support decision making in a myriad of domains. Expert systems are used to solve problems in well defined, narrowly focused problem domains, whereas advisory systems are designed to support decision making in more unstructured situations which have no single correct answer. This paper provides an overview of advisory systems, which i...
