comply with regulatory oversight and to be confident in the overall quality of the final product. Though there is some ambiguity in the industry as to the exact definition of validation, it is clear that all components of the sealing process that influence package integrity must be monitored, measured, and controlled. Moreover, equipment must perform the heat sealing function in a repeatable, i...

The subject of the study was the clinical analysis of six different sealing materials over a 12-months period. It was necessary to prove the clinical success of sealing with flowable composite with the use of adhesive system and preventing effect of sealants on caries developement. Our study included children aged from 6 to 15, and we sealed 326 teeth with materials from the group of flowable c...

Mineral Trioxide Aggregate (MTA) is a new material recently approved by the FDA for use in pulpal therapy. MTA has been reported to have superior biocompatibility and sealing ability and is less cytotoxic than other materials currently used in pulpal therapy. This report is a review of MTA's physical and biological properties and the clinical techniques of direct pulp capping, apexification, an...

BACKGROUND Cyclic redistribution of air within the cuff during respiratory pressure changes creates a self-sealing mechanism which allows tracheal sealing, despite tracheal airway pressure being above baseline cuff inflation pressure. The aim of the present study was to investigate the effect of continuous automated cuff pressure regulation on tracheal sealing during cyclic respiratory pressure...

Introduction. This study compared streamlined liner of the pharynx airway (SLIPA) and I-gel noninflatable, single-use, supraglottic airway device (SAD) performance in anesthetized, paralyzed adults. Methods. Eighty adults (ASA physical statuses I-III) who were undergoing elective procedures under general anesthesia with an SAD were enrolled in this prospective, randomized, single-blind study. S...

This paper presents results of a systematic investigation to characterize the sealing of micromachined cavities using chemical vapor deposition (CVD) methods. We have designed and fabricated a large number and variety of surface-micromachined test structures with different etch-channel dimensions. Each cavity is then subjected to a number of sequential CVD deposition steps with incremental thic...

On 31 July 2003 BfR provided information on the occurrence of semicarbazide (SEM) as a contaminant in various foods. This was based on information from the European Food Safety Authority (EFSA). The common feature of these foods was that they were packaged in glass jars or bottles. Initial study results indicated a semicarbazide content of up to 15 μg/kg food. One possible source given for semi...

In industrial assembly lines, seam sealing is a painting process used for making watertight seals or for preventing rusting. In the process, sealant is painted on seams located at the joints of pressed metal parts. We developed a sealing robot system that adjusts the sealing gun motion adaptively to the seam position sensed by a range sensor (a scanning laser rangefinder which senses profile ra...
