Scarborough touches on these and on many other matters but too often does not press the enquiry home. This may be due partly to limited space allowed for a various and complicated subject, for which the quantity and the quality of the evidence are alike uneven. There are appendices on medical biographies, on sources and problems, on the vexed question ofhuman dissection in Roman times, and on R...

In the clinical practice, it is much more efficient to use NiTi rotary files compared to hand instrumentation. However, misuse of NiTi rotary files can result in procedural errors such as transportation, ledge, perforation, and file separation. Generally, following suggestions could be considered to avoid these errors. 1. Enlarge the coronal half of the root canal before preparing the apical pa...

The morphology and structure of 2,2':6',2″-ternaphthalene (NNN) deposited on muscovite mica(001) substrates was investigated by scanning force microscopy (SFM) and specular X-ray diffraction measurements. Consistently, both methods reveal the coexistence of needle-like structures with a {111} contact plane and {001} orientated island-like crystallites, which are built up by almost upright stand...

A semantics is given to possibilistic logic, a logic that handles weighted classical logic formulae, and where weights are interpreted as lower bounds on degrees of certainty or possibility, in the sense of Zadeh's possibility theory. The proposed semantics is based on fuzzy sets of interpretations. It is tolerant to partial inconsistency. Satisfiability is extended from interpretations to fuzz...

In this paper we study different concepts of independence for convex sets of probabilities. There will be two basic ideas for independ­ ence. The first is irrelevance. Two variables are independent when a change on the know­ ledge about one variable does not affect the other. The second one is factorization. Two variables are independent when the joint con­ vex set of probabilities can be decom...

treatment of an injury sustained in a fall. It appears that she and her family were travelling to tlieir home, a village near to Ahmedabad, from Oodeypoor, where they had gone on purpose to visit some shrine held in great repute amongst the natives of these parts. Whilst on their homeward journey, the woman and four female relations were travelling in a country bullock cart, about 20 miles from...

We consider a simple model for the growth of isolated steps on a vicinal crystal surface. It incorporates diffusion and drift of adatoms on the terrace, and strong step and kink edge barriers. Using a combination of analytic methods and Monte Carlo simulations, we study the morphology of growing steps in detail. In particular, under typical Molecular Beam Epitaxy conditions the step morphology ...

This paper describes advances in the development of a know ledge-based front-end for the s ta t is t ics package GLIM 3.77, employing logic programming methods and tools, including sigmaPR0L0G and APES. The domain of application computer-based s ta t i s t i ca l analysis requires that a changing knowledge base be handled by the system, GLIMPSE*. The developing system is suitable for users with...

data and associated hypotheses were constructed, as well as exploring the way in which the relationship between research and policy debates are understood and conducted. Those with established interest in unemployment and health will be familiar with many of the ideas that are presented, while those working in public health or entering upon social science research which may have significant pol...

The paper proposes a sim ple m ethodology to estim ate an affluence line that depends on the know ledge of the incom e distribution and the poverty line for a given population. The idea that poverty is m orally unacceptable and can be eradicated through redistribution of w ealth provides the grounds for the m ethodology. The line is defined as the value that delim itates the aggregated incom e ...
