Through painstaking trial and error, they figured out the right combination of barrier materials to protect the work from the pressure of the staple gun: padding underneath the stapler, silicone release mylar over the wax surface, and a mylar strip positioned where the staple releases, so it doesn't cause indentation.
The combination of barrier membrane and hydrophilic matrix system was utilized as a strategy to modulate drug release from hydrophilic matrices and to reduce the overall variability in release.
One data set, based on 1,148 cows (115 herds), was from farms using feed barriers with post-and-rail designs (86 herds) and combinations of barriers (29 herds).
For example, in Chemistry, much like most other departments, time constraints are a significant barrier; however, "instructional challenges" and "inadequate resources" are also significant barriers; this particular combination of top barriers is unique among the departments in this study.
The analysis incorporates results of more than 3000 simulations for various combinations of barrier thickness, waste loading rate, initial void ratio, compression index, hydraulic conductivity and dispersion coefficient.
Since 2005, Congress has appropriated $2.7 billion for the Secure Border Initiative, a combination of physical barriers and a so-called virtual fence, a highly promoted system of cameras and sensors.
What made the difference in Europe for the Japanese auto industry was a benign combination of lowered barriers to Asian imports, evolving European habits in car purchasing, and the automakers' decisions to start replacing imported models with new ones designed locally.
Marine LNG vessels have differently designed tanks and it is demonstrated that the combination of physical barriers makes direct thermal input to the LNG inner tank more limited than hypothesized by some, but if it occurs these tanks cannot rise to a pressure sufficient to cause a large flash of liquid and consequent BLEVE event of a scale hypothesized in the literature.
There is a common belief that women hit a glass ceiling later in their careers, whereby a combination of invisible barriers prevent women from advancing to senior leadership roles.
The low level of indica/japonica admixture in Indonesian varieties may be due to a combination of sterility barriers, field level ecotype differences, and visible differences in grain characters which enables farmers to differentiate subspecies and select pure seeds to plant for the next generation.
