Background:Various impression techniques have been proposed for making implant prostheses. Impressions are made at level –closed and open tray impressions, as well abutment impressions. Closed copings used to make the The limitations associated with copings, including expensive ones, pose a significant challenge in limited mouth-opening cases, customization of is not feasible.Aim: This study ai...

BACKGROUND Health care costs in Canada continue to rise. As a result of this relentless increase in healthcare spending, ways to increase efficiency and decrease cost are constantly being sought. Surgical treatment is the mainstay of therapy for many conditions in the field of Otolaryngology- Head and Neck Surgery. The evidence suggests that room exists to optimize tray efficiency as a novel me...

A rigorous model for staged high purity distillation based on rst principles is developped. The importance of the tray hydraulics to obtain good agreement between simulation and experiment is demonstrated. Analytical expressions to derive the hydraulic time constants l, v and the vapor constant for models with simpli ed tray hydraulics are presented. The validity of these key parameters is veri...

• Per AFNOR Certification guidelines, a preliminary study was conducted where the relative accuracy, linearity, detection and quantification limits, selectivity (inclusivity and exclusivity) and practicability of the Colilert-18/Quanti-Tray method were assessed using samples of distribution water and fountain water spiked with strains of both coliform bacteria and E. coli. All the assessed perf...

Let \(\varSigma \) and \(\varPi be disjoint alphabets, respectively called the static alphabet parameterized alphabet. Two strings x y over \cup \varPi of equal length are said to match (p-match) if there exists a renaming bijection f on which is identity maps characters those so that two become identical. The indexing version problem finding p-matching occurrences given pattern in text well-st...

Methylisothiazolinone (MI) is a preservative found in cosmetic and industrial products. Contact dermatitis caused by either methylchloroisothiazolinone/methylisothiazolinone (MCI/MI or Kathon CG) or MI has shown increasing frequency. The latter is preferably detected through epicutaneous testing with aqueous MI 2000 ppm, which is not included in the Brazilian standard tray. We describe a series...

This paper describes a practical stereo vision system for position measurement and recognition in an autonomous food-tray-carrying robot. Our food tray carrying robot delivers and collects food trays in medical care facilities. The vision system must position and recognize tables and trays for the robot to manipulate the trays. We have developed edge detectin techniques for the measurement of t...
