The present study is an investigation of the effect of pulse duration on properties of coatings formed on aluminium alloy in alkaline solution via using of high voltage cathodic pulses.
Influences of treatment temperature and duration on properties of the carburized layer were investigated with optical microscope, atomic force microscope, X-ray diffractometer, micro- and nano-indenters, and pin-on-disc tribometer.
In addition, the aging effect during the duration of the hydrophilic property is also studied to investigate the production cost for the industrial applications.
Animal and human timing display both properties, since mean timing estimates vary linearly and usually accurately with temporal standards (mean accuracy property) while the variability of temporal performance increases linearly with standard duration (scalar property of variance) [28] [30].
Helprin emphasizes the distinction between ideas (this is what he thinks Jefferson had in mind as common property) and art, while Anderson focuses on the limited duration of copyright, noting that intellectual property is not to be treated as other property, because it is the basis of common culture.
The key parameters considered are: hazard severity (toxicity), scale and duration of operation, and physical properties (volatility or dustiness).
No apparent differences were identified in their scotoma properties, duration of disease, fixation locus or visual function.
Other sources of variability include differences in populations (subjects with/without asthma, moderate vs severe allergic disease), differences in preseasonal treatment (or duration of treatment) and physical/chemical properties of the pollen exposure.
However, many factors influence cement penetration including magnitude and duration of the force applied, properties of the bone cement used, amount of bone bleeding, anatomy, porosity, and (not least) preparation of the acetabular bone (Noble and Swarts 1983, Juliusson et al. 1994, Graham et al. 2003, Hogan et al. 2005, Flivik et al. 2006).
