It is with an acute sense of the significance of the physical agent modalities issue on the future of our profession that [ fully endorse the position taken and the recommendations made by Wilma L. West and Ruth Brunyate Wiemer (A]OT, December 1991, pp. 1143-1147). There can be no denying that the health care system of today is economically and politically driven. Too frequently, patient treatm...

Occupational therapists interested in physical disabilities practice (N = 629) responded to a questionnaire regarding their use of, training in, and opinions on physical agent modalities. Therapists in hand rehabilitation were the most frequent users of these modalities. Of the listed modalities, the most frequently used was hot and cold packs; the least used was ultrasound. The modalities used...

The process of sealing of damaged axons was examined in isolated strips of white matter from guinea pig spinal cord by recording the "compound membrane potential," using a sucrose-gap technique, and by examining uptake of horseradish peroxidase (HRP). Following axonal transection, exponential recovery of membrane potential occurred with a time constant of 20 +/- 5 min, at 37 degrees C, and extr...

BACKGROUND During embryonic development, epithelia with free edges must join together to create continuous tissues that seal the interior of the organism from the outside environment; failure of epithelial sealing underlies several common human birth defects. Sealing of epithelial sheets in embryos can be extremely rapid, dramatically exceeding the rate of adherens junction formation by epithel...

Newly available materials for retrograde obturation should have their sealing properties evaluated. The goal of this study was to evaluate the sealing ability of Endo CPM sealer, an MTA-based endodontic cement. Single-rooted extracted human teeth were endodontically treated. After apical sectioning, retrograde cavities were prepared. Teeth were divided into five experimental groups (n=12), in w...

Sealing treatment is a post-surface of the plasma spray coating process to improve corrosion resistance material. In this study, effect sealing on and adhesive strength spray-coated alumina coatings was analyzed. For sealing, an epoxy resin applied surface coated specimen using brush. The subjected salt test for up 48 hours microstructural analysis revealed that in layer/base material interface...

Because current remote monitor systems can’t deal with problems of real-time transmissions in the bad condition of network very well, this article presents a study which is combined with the evaluation of video streams, adjustment and sealing user-defined data pockets and discarding useless data pockets. The goal of this solution is to transmit video information of national grain depot. And its...
