The 52.7 MHz deuteron (2H) solid state NMR spectra of benzene-d6 adsorbed on microcrystal­ line boron nitride and on two graphitized carbon blacks (Graphon and Sterling MT) were measured at temperatures between 75 and 120 K. Both on boron nitride and on the graphitized carbons the benzene molecules exhibit hexad axis rotation which is fast on the NM R time scale. From the spectra of benzene on ...

We study users’ incentives to become cybercriminals when network security is interdependent. We present a game-theoretic model in which each player (i.e., network user) decides his type, honest or malicious. Honest users represent law-abiding network users, while malicious users represent cybercriminals. After deciding on their types, the users make their security choices. We will follow [29], ...

abstract this article tries to have a look at 40 images which shows ood player in sasani to safavi periods. these images can be considered as documents for more information about ood instrument. permanent elements in these images are the base of the analysis in this research. two types of figures were being considered as permanent elements: basic figure and non basic figure. in this research ba...

The anisotropic spin-lattice relaxation of deuterated hexamethy lbenzene (HMB-d,,) was measured at -36 and 70°C. The anisotropy is due to the anisotropic sixfold reorientation of the molecule about its hexad axis, and a model is presented to explain quantitatively the anisotropy, considering only single-particle relaxation. The temperature dependence of T, was measured, and the activation energ...
