The objective of the present empirical study was to test “bridging assumptions,” that’s, to see how closely the analysis of the objective macro-structural conditions determining the travel mode choice comply with the situation as perceived by the M respondents. The adopted methodology is based on a contingent valuation (CV) survey. Stated Preference (SP) surveys, also called self-stated preferences for research or services, have been widely applied in the areas of marketing and travel demand...
Biosynthesis techniques have a number of advantages over other methods for producing silver nanoparticles (AgNPs), which provide a wide range of applications. The present work highlights the biosynthesis of AgNPs by mixing pear leaf aqueous extract with silver nitrate, and the formation of AgNPs was observed by the change of mixture color from yellow to dark brown and visible spectrophotometry. Moreover, the effect of pH, reaction time, AgNO3 concentration, extract volume and temperature on...
