is paper considers the M/M/NN repairable queuing system. e customers’ arrival is a Poisson process. e servers are subject to breakdown according to Poisson processes with different rates in idle time and busy time, respectively. e breakdown servers are repaired by repairmen, and the repair time is an exponential distribution. Using probability generating function and transform method, we ob...

The main concentration of the present work is to evaluate and analyze economic nature a system reliability model which allowed operate under varying weather conditions – normal abnormal. In this context consisting two non-identical units developed in initially unit operative duplicate at standby. Single repairmen/server comes immediately rectify fault whereas abnormal repair not feasible. techn...

OBJECTIVE To investigate the relationship between removable dentures and swallowing and describe risks. METHODS Twenty-four patients with removable dentures who were referred for videofluoroscopic swallowing study (VFSS) were enrolled. We evaluated the change of swallowing function using VFSS before and after the removal of the removable denture. The masticatory performance by Kazunori's meth...

This investigation deals with transient analysis of cold standby system with n units . Chapman-Kolmogorov equations are developed for repair facility with two repairmen and solved by using matrix technique. Availability and reliability factors have been obtained with probability of the system. A particular case has also been discussed.

The aim of this study was to compare the ability of 46 isolates of Candida albicans to produce mycelial form with oral source in three groups of individuals including, removable appliance wearers, non-wearers and oral medicine patients. Saliva samples were obtained from all subjects along with a foam imprint from the fitting surface of the upper removable appliance in the case of patients. Colo...

Photomultiplication Type Organic Photodetector with Removable Top Electrode In article number 2200651, Takao Someya, Tomoyuki Yokota, and co-workers develop airstable photomultiplication type organic photodetector removable top electrode. The developed structure enables the direct continuous analysis of active layer after operation in air.

Aim of this study was to determine the prevalence of removable denture (complete and partial) deliveries through Croatian Public Health Service (covered by insurance) in different districts of Croatia and to compare the two periods: 1996 to 2001 and 2002. Number of dentures delivered was obtained from Croatian Institute for Health Insurance for the district of Zagreb, Rijeka, Split and Karlovac...

In this study, the adaptation of patients to removable partial dentures was evaluated related to articulation of Turkish phonemes. Articulation of /t,d.n,l,r/, /g,k/, /b,p,m/ and /s,z,ş,v,f,y,j,h,c/ phonemes were evaluated by three speech pathologists, on records taken from 15 patients before the insertion of a removable partial denture, just after insertion, and one week later. The test consis...

Orthodontists from different backgrounds may have different opinions about removable and fixed orthodontic appliances, but there have been few objective comparisons of their relative treatment effectiveness. It is the purpose of the present study to analyze objectively the effectiveness of these two types of appliances. Eighty cases involving patients who had been treated with removable applian...

the main goal of this study was to evaluate differences in stress distribution relevant to the number of implants under an anterior bridge when combined with a removable partial denture in the posterior region.four three-dimensional finite element models (3d fem) were designed from a mandible containing an implant-supported bridge extending between canines, and a bilateral distal extension remo...
