Surface area has long been thought to influence the corrosion behavior of medical devices although this phenomenon has not been systematically investigated. Because many nitinol implants are offered in a range of sizes, understanding the influence of device surface area on corrosion susceptibility is ...
Specific surface area and porosity measurement is closely connected with particle external surface area. Besides, the key of gas sorption is the adsorbate can be efficiently attached onto particle surface or be filled into pores, thus, no more important than particle surface purity. The purpose for...
Since R is not coercive, one has to introduce some bound on the class of admissible functions, and one of the bounds that was suggested in [4, p. 259] for the case of radial functions was the surface area of the body. In this case Eggers was able to conclude that a minimizer of ...
The resistance depended strongly on the contact area of the stem with the solution, however, thus causing bias in the evaluation of root surface area. This work is a new contribution for the understanding of current pathways in the root system as exposed to an external electric field and for...
A concomitant increase in sensible heat flux (H/resulted in the increase of a Bowen ratio from 0.83 to 1.57. Partial correlation analysis indicated that surface resistance (R-s/normalized by leaf area index (LAI; R-s: LAI) increased by 50% under drought conditions and was the dominant ...
In subject area: Physics and Astronomy Surface defects are imperfections such as surface roughness, pores, and coarse grains that can lead to material failure by initiating cracks, reducing strength, ductility, and fatigue life. These defects are influenced by machining parameters and can be mitigated...
After etching the antidots, we defined and etched a Hall bar by optical lithography and wet chemical etching. By etching the Hall bar after nanostructuring, we remove differently deep etched antidots, which occur along the perimeter of the patterned area between the potential probes so that they...
surface area and the roughness parameter values and regression analyses were applied to validate the results in case of the applied technological data. The main finding of the study is that minimum evaluation areas can be clearly designated and, depending on the different roughness parameter–...
The results indicate that the self-excited vibrating circular arc-surface bulldozing plate could effectively improve the resistance reduction effect during the operation around the resonance point. With this model, the average error of the horizontal working resistance was 7.52%, and the average error ...
For north–south row orientation, all soil is sunlit and shaded at various times of the day. Surface resistance, rsc, for densely growing vegetation is often computed in the ‘single-layer’ PM as a function of leaf area by assuming all leaves function as resistors in parallel: [29]rsc=...
