[PDF] Wilson loops in N=4 super Yang-Mills theory: …

 · We study Wilson loops in $mathcal{N}=4$ super Yang-Mills (SYM) theory which are nonconstant in the scalar $({mat{S}}^{5})$ directions and open string solutions associated with them in the context of AdS conformal field theory correspondence. An interplay between Minkowskian and Euclidean pictures turns out to be nontrivial for time-dependent Wilson loops. We find that in the …

Ball Mill

The Planetary ball mills are the most popular mills used in MM, MA, and MD scientific researches for synthesizing almost all of the materials presented in Figure 1.1. In this type of mill, the milling media have considerably high energy, because milling stock and balls come off the inner wall of the vial (milling bowl or vial) and the effective centrifugal force reaches up to 20 times gravitational acceleration.

 · As a routine wood source for a pulp mill, recent past studies have shown that intensivelymanaged, short-rotation hardwood plantations are not cost effective. The objective of this study was to determine if these plantations may be cost effective as "green" inventory, replacing some portion of high cost remote woodyard inventory. Three southeastern pulp mills were used as case …
