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...

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...

Lung biopsies are often used to aid in the diagnosis of cancers. However, procedure carries dual risk air (pneumothorax) or blood (hemothorax) filling pleural cavity, increasing a collapsed lung and chest intubation. This work demonstrates effectiveness polyurethane-based shape memory polymer foam as biopsy tract sealant. The impact diameter, length, pore size, effect was evaluated determine id...

The successful placement of Laryngeal Mask Airway (LMA) Supreme in adults largely depends on right selection of its size. Most anesthesiologists determine the size of LMA according to patients' body weight, which does not always work well. An alternative method should be established to guarantee higher efficacy of ventilation through LMA Supreme placement. This controlled study was designed to ...

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...

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...
