An ‘operating characteristics’ (OC) curve is a simple tool that has been in use in quality control for many years but does not seem to be widely applied in the particulate sampling field. The OC curve provides the probability that a lot of material will be deemed to meet a specification (will be found to have an assay that falls above (or below) a specified level, given the true assay of the lo...

OBJECTIVE To investigate the relationship between the quantity of Candida colonies in saliva and oral candidiasis (OC), as well as to identify the threshold for distinguishing oral candidiasis from healthy carriage. METHODS A diagnostic test was conducted in 197 patients with different oral problems. The diagnosis of OC was established based on clinical features. Whole saliva samples from the...

We prove two formulae that express the Alexander polynomial 1C of several variables of a plane curve singularity C in terms of the ring OC of germs of analytic functions on the curve. One of them expresses1C in terms of dimensions of some factors corresponding to a (multi-indexed) filtration on the ring OC . The other one gives the coefficients of the Alexander polynomial 1C as Euler characteri...

Let C ⊂ Pr be a general curve of genus g embedded via a general linear series of degree d. The well-known Maximal Rank Conjecture asserts that the restriction maps H(OPr(m)) → H(OC(m)) are of maximal rank; if known, this conjecture would determine the Hilbert function of C. In this paper, we prove an analogous statement for the hyperplane sections of general curves. More specifically, if H ⊂ Pr...

This paper presents a practical and effective novel approach to curve fit electromechanical EM overcurrent OC relay characteristics. Based on singular value decomposition SVD , the curves are fitted with equation in state space under modal coordinates. The relationships between transfer function and Markov parameters are adopted in this research to represent the characteristic curves of EM OC r...

OBJECTIVE To determine the frequency and reasons of conversion of laparoscopic cholecystectomy (LC) to open cholecystectomy (OC) in a tertiary care teaching hospital. METHODS A prospective analysis of conversion of laparoscopic to OC was performed in one Surgical Unit of Civil Hospital Karachi, from 1st September 1997 to 31st May 2005. There were 1238 patients in the series. The inclusion cri...

BACKGROUND Computer-assisted analyses were used to examine ultrasound image attributes of human dominant ovarian follicles that developed during natural and oral contraceptive (OC) cycles. We hypothesized that image attributes of natural cycle follicles would quantitatively differ from those in OC cycles and that OC cycle follicles would possess image attributes indicative of atresia. METHODS...

Abstract Aim The purpose of this study was to investigate the learning curve open anterior mesh repair for groin hernia by assessing recurrence rates, surgical complications, and operative times in relation number procedures performed trainees. Materials & Methods Nationwide data on residents were collected from Swedish Hernia Register between 2005 2020. Data analyzed a cohort carried out s...

BACKGROUND AND OBJECTIVE Reformulated OxyContin(®) (oxycodone-HCl controlled release) tablets (ORF) became available in the United States in August 2010. The original formulation of OxyContin(®) (oxycodone-HCl controlled release) tablets (OC) used a delivery system that did not provide inherent resistance to crushing and dissolving. The objective of this study was to compare the pharmacokinetic...
