In this investigation the denture retention was measured and the influence of denture -retention on ima'sticatory efficiency was examined. The investigation was iperf armed on 36 comiplete denture wearers. The test of masticatory efficiency wals used according to Ni'kšić (1965). The meaisuriinig of denture retention was made by specially constructed mechanical scale, which wa's designed so that...

The coupled influence of input suspension concentration (Ci), ionic strength (IS), and hydrodynamics on the transport and retention of 1.1 microm carboxyl-modified latex colloids in saturated quartz sand (150 microm) under unfavorable attachment conditions (pH 10) was investigated. The percentage of retained colloids in column experiments decreased with Ci at intermediate IS conditions (31 or 5...

Profile analysis of mycolic acid ester patterns of Mycobacterium tuberculosis, Mycobacterium bovis, and Mycobacterium bovis bacillus Calmette-Gúerin (BCG) using high-performance liquid chromatography indicated that separation of BCG from M. tuberculosis and M. bovis by elution and relative retention times is possible. Mycolic acid patterns of BCG eluted from the column 0.5 min before M. tubercu...

The main purpose of this study is to evaluate the effect of staffs' customer orientation on customer satisfaction, commitment and retention. For this aim, the model of customer orientation of service staff, offered by Thurau was combined with customer orientation model of Donavan and Hoctt and a new model was devised for Mellat Banks of North West of Iran. The trend of this research is applied,...

BACKGROUND Transverse nasal crease is an uncommonly reported entity. It likely represents an embryologic fault line. Transverse nasal milia have also been reported in the same location, both as an isolated finding and in a transverse nasal crease. This observation suggests they are variants of the same entity. OBSERVATIONS Two cases, one of transverse nasal crease with milia and one of transv...

The processes contributing to the durability of repetition priming in picture naming and its decline across a week were assessed in two experiments with Spanish-English bilinguals. In Experiment 1, both picture identification and word retrieval processes of picture naming exhibited facilitation after a week. Word retrieval priming declined substantially relative to a 10-min retention interval, ...

Reichard and E&born (1) demonstrated that rats selectively incorporated thymidine-N16 as deoxyribonucleic acid thymidine, and their observation has been extended by numerous investigators to include many organisms and several isotopic labels. Tritiated thymidine has been particularly useful as a means of marking DNA for study by high-resolution radioautography (Z), and the histological distribu...

Two orders of addition were compared when preparing paper handsheets from recycled copy furnish in combination with nanofibrillated cellulose (NFC), cationic starch, colloidal silica, and retention aid (cPAM; polyacrylamide). Faster dewatering higher fine-particle obtained at equal optimized dosages additives the silica was added last, after cPAM. The same order also provided a gain paper’s ten...

introduction: a limited number of studies have evaluated factors influencing the retention of fixed prostheses cemented to implant abutments. the aim of this study was to compare the effect of varying degrees of screw access channel obturation on retention of implant-supported cast fixed restorations. materials  & methods: in this experimental study, 40 implant abutments with a diameter of 4.5 ...
