A subset of vertices in a graph G is total dominating set if every vertex adjacent to at least one this subset. The domination number the minimum cardinality any and denoted by ?t(G). having nonempty intersection with all independent sets maximum an transversal set. ?tt(G). Based on fact that for tree T, ?t(T) ? ?tt(T) + 1, work we give several relationships between trees T which are leading cl...

The total dominator coloring of a graph is the such that each object (vertex or edge) adjacent incident to every some color class. minimum number classes called chromatic graph. In (A.P. Kazemi, F. Kazemnejad and S. Moradi, Contrib. Discrete Math. (2022).), authors initiated study found useful results, presented problems. Finding numbers cycles paths were two them which we consider here.

the etiopathogenesis of dementia in alzheimer's disease (ad) is still unclear. however, long-term oxidative stress is believed to be one of the major contributing factors in progression of neuronal degeneration and decline of cognitive function in ad. in order to assess the presence of oxidative stress in ad, we examined the enzymatic activities of the erythrocyte cu-zn superoxide dismutase (cu...

introduction: to describe the underlay tympanoplasty technique using an acellular dermal graft(alloderm) for tympanic membrane (tm) reconstruction in a guinea pig model and to demonstrate the feasibility of the technique using alloderm tissue harvested from the prepuce as a source of tissue for future grafting in human tm reconstruction.   materials and methods: the prepuce was divided during c...
