The objective of this study was to assess the efficacy and safety of electroacupuncture in 138 patients with earthquake-caused PTSD using Randomized Controlled Trials (RCTs). 138 cases enrolled were randomly assigned to an electro-acupuncture group and a paroxetine group. The electro-acupuncture group was treated by scalp electro-acupuncture on Baihui (GV 20), Sishencong (EX-HN 1), Shenting (GV...

Let n = 2k + 1 with 0 < k ∈ Z and let Mk be the subgraph induced by the kand (k + 1)-levels of the n-cube graph. A system of numeration according to which the nonnegative integers are written as restricted growth strings, so called by Arndt and Ruskey, has specifically the k-th Catalan number Ck = (n k ) /n expressed as 10k. This permits a linear ordering of the vertex set of a quotient graph R...

The metalloenzyme nitrogenase is utilized by microbial diazotrophs to accomplish the majority of biological nitrogen fixation. Many different forms of the enzyme nitrogenase are known to exist. They are categorized by the type of metal cluster providing the N2-binding site, which is also the active site of the enzyme. The nitrogenase best-characterized to date has an active site with the compos...

in this paper, two new hamilton operators are defined and the algebra of dual split quaternions isdeveloped using these operators. it is shown that finite screw motions in minkowski 3-space can be expressedby dual-number ( 3×3 ) matrices in dual lorentzian space. moreover, by means of hamilton operators, screwmotion is obtained in 3-dimensional minkowski space 3r1
