An aperture is a hole or an entrance which is passing light.

magnification images of single ZnO nanostructure in Fig. 1(d) and (e) reveal that they are composed of central axial nanowires surrounded by radially oriented nanorods with 6-fold structural symmetry. Fig. 1(f) shows the side-wall image of hierarchical ZnO nanostructure with widths of 70–-120 nm and average length of around 600 nm. The high-magnification image of the single nanorod on the s
magnified by the same amount would be over a mile(1.6 kilometer) tall.
Even with an ordinary microscope, you must look closely to see bacteria. Using a magnification of 100 times, one finds that bacteria are barely visible as tiny rods or dots. One cannot make out anything of their structure. Using special stains, one can see that some bacteria have attached to them wavy-looking 몷hairs몸 call

(2) 치료의 초점
ⅰ) 환자가 다른 방식으로 생각하도록 설득시키는 인지적 재구조와 작업(Ellis 의 RET)과 여러 면에서 공통적이다.)
ⅱ) Beck의 인지적 치료가 항우울제를 투여하는 것보다 성공하는 비율이 높다는 것이 입증되어 있다 (Rush와 그의 동료들,197
