The value of the x-ray film survey in tuberculosis case finding has been corroborated by many studies during the past 30 years. In numerous surveys emphasis has been placed on age, sex, race, occupation, economic status etc.; other studies have shown that there is a high yield of unsuspected active pulmonary tuberculosis in admissions to general hospitals. It is the purpose of this paper to dir...

Finding flexible schedules is important to industry, since in many environments changes such as machine breakdowns or the appearance of new jobs can happen at short notice. In this paper a minimax formulation is used to develop a coevolutionary algorithm for finding worst case flexible schedules. A population of schedules is used to locate the schedule with the best worst case performance, whil...

Advances in molecular biology and the tools and techniques available for analysing molecular structure are providing a rapidly increasing deluge of information that maps fundamental genetic structures in humans and other organisms. Intelligent support is essential for managing and interpreting this overwhelming amount of data, and one of the most important tasks faced currently is the analysis ...

The odontogenic fibroma is a rare, benign tumor of mesodermal origin, and one of the most ill-defined and least understood of all odontogenic neoplasms. 1 It presently is thought to originate from either dental follicle, periodontal ligament, or dental papilla. 2 Bhaskar reported the lesion as being the most common odontogenic tumor comprising approximately 23°70 of all odontogenic lesions. 3 T...

The detection of refractive errors includes effective screening programmes in the school or community. However, the lack of human and other resources often prevent such programmes from occurring. Therefore, patients with many conditions, both refractive and nonrefractive, present at clinics. The separation of these patients into refractive and non-refractive conditions is important in the good ...

The process of case-finding was studied in 100 consecutive patients with pulmonary tuberculosis treated by the Chest Clinic, Penang Hospital. The median time from the onset of the illness until the initial medical consultation was two weeks (patient's delay). This delay was longer in males, patients with lower than secondary education and drug abusers. Only 47% of patients were put on treatment...

We survey recent average-case results (and prove a new one) for the solution of nonlinear equations f(x) = 0 of one variable. We assume that f changes in sign at the endpoints of an interval and show that bisection is not optimal (as in the worst Case) for a number of classes. 0 1989 Academic Press, Inc. We study the approximate solution of a nonlinear equationf(x) = 0. It is assumed that f: [O...

BACKGROUND The under-reporting of incontinence in older persons is well known. However, the general practitioner's (GP's) knowledge of incontinence in this population is less wall documented. AIM To examine the knowledge of Irish GPs regarding incontinence in patients aged over 75, and to examine the relationship between incontinence and cognitive function in this age group. METHOD Sixty-fo...
