Implicative goal

We syntactically restrict S-formulas (which are not explained here) to implicative goals (as in [Fribourg 90, 93]), that is statements G of the form ... 

Properties are thus a particular case of implicative goals. Note that Y is necessarily always empty for a property. 

The initial goal is property translated into an implicative goal. 

Due to our syntactic restriction to implicative goals, only three inference rules of extended execution are actually required in our context. 

Deflnition 9-1 The rule of definite clause inference (denoted DCI) is a natural extension of SLD resolution to implicative goals. Given a goal G, the selected atom is chosen within and the mgu may only bind undecided variables of G. All new variables introduced in the resolvent goal are undecided variables.

The Safety Goal Policy Statement was published to define acceptable radiological risk IVom nuclear power plant operation, and by implication provide a de minimus risk to be assured without cost considerations. Safety beyond the minimum requires cost-benefit analysis. Since being promulgated, bulletins and generic letters have been imposed to enhance safety, under the provisions of 10 CFR 50.109, the Backfit Rule. 

The 12 principles won t all be met in most real-world applications, but they provide a worthy goal to aim for and they can make chemists think more carefully about the environmental implications of their work. Success stories are already occurring, and more are in progress. Approximately 7 million pounds per year of ibuprofen (6 billion tablets ) is now made by a "green" process that produces approximately 99% less waste than the process it replaces. Only three steps are needed, the anhydrous HF solvent used in the first step is recovered and reused, and the second and third steps are catalytic. 

For example, if our goal were to show that the end-time of the schedule, x, was equal to a particular value, but we wanted to verify this not for X directly, but for some ancestor of x, then we could use the following implication, in addition to our conditions for start-time dedue-tion (see Section IV, A, 1, a) to carry out the reasoning. 

In this case, we have omitted one intermediate step of reasoning, but in general, there could be many steps between the original goal and the operational predicates. Any future application of the condition will not be required to perform those intermediate steps, or any of the associated search for implications with matching consequences. 

In other cases, clinical information is incomplete. One goal of this paper is to suggest some areas where clinicians and clinical researchers might focus their attention to learn more about the implications of PCP abuse. 

Delineate the clinical course of follicular indolent and diffuse aggressive non-Hodgkin s lymphoma and the implications for disease classification schemes and treatment goals. 

The new Biocidal Products Directive is examined, which closes the gap in European legislation for products such as disinfectants and anti-foulants where there has not, until now, been a Europe-wide standard. The basic goals of the directive are to simplify and harmonise Europe s regulatory framework for biocides, and to remove trade barriers within the EU, and to improve the protection of both human health and the environment. The new directive must be enforced as national legislation in all member countries by 14 May 2000. Details are given of products defined within the directive, and ways in which the directive will be put into practice in the UK are discussed. The implications of the legislation on the industry in terms of time and money spent on testing for each active substance involved are examined.
