This experiment was conducted to study the effect of planting and mulching methods on the some characteristics of the flue-cured tobacco leaf. The results obtained are summerized as fellows. 1.Plant type was changed according to planting time and mulching methods. As the plant type of early plating and mulching plot was changed to conical shape, so the light condition received of the plot was improved. 2.As the weight of unit leaf area and percentage of dry matter were high and dried up leaf ratio, leaf area contraction ratio and proportion of midrib were low in earley setting plot, so the leaf quality was good. But weight of a leaf and LAI were small. 3.In the view of leaf quality among the diffent leaf position, the lower and middle leaves of the non-temporary planting plot were especially good. 4.To increase the yield and to improve the leaf quality, it seems desirable to improve the leaf quality by early setting and to increase LAI by increasing the number of leaves.
Electrical Characterization of Electronic Materials Using FIB-assisted Nanomanipulators
Roh, Jae-Hong,You, Yil-Hwan,Ahn, Jae-Pyeong,Hwang, Jinha Korean Society of Microscopy 2012 Applied microscopy Vol.42 No.4
Focused Ion Beam (FIB) systems have incorporated versatile nanomanipulators with inherent sophisticated machining capability to characterize the electrical properties of highly miniature components of electronic devices. Carbon fibers were chosen as a model system to test the applicability of nanomanipulators to microscale electronic materials, with special emphasis on the direct current current-voltage characterizations in terms of electrode configuration. The presence of contact resistance affects the electrical characterization. This resistance originates from either i) the so-called "spreading resistance" due to the geometrical constriction near the electrode - material interface or ii) resistive surface layers. An appropriate electrode strategy is proposed herein for the use of FIB-based manipulators.
