Catechol oxidase has been solubilized from the particulate fraction of apple peel using Triton X-100, dialysis and butanol extraction. The partially purified enzyme retained activity during lyophilization in the presence of mercaptobenzothiazole. The substrate specificity and pH optima of the enzyme are reported.
Let φ be Euler's phi function. Let n be a square-free positive integer such that gcd(n,φ(n))=qgcd(n,φ(n))=q, q a prime, and if p|np|n is prime, then q2∤(p−1)q2∤(p−1). We prove that a vertex-transitive graph Γ of order n is isomorphic to a Cayley graph of order n if Nike Free 5.0 Mens Canada
and only if Aut(Γ)Aut(Γ) contains a transitive solvable subgroup.
A pair of identical twins in whom cerebral berry aneurysms were found is reported. One presented with epilepsy, and the aneurysm was discovered incidentally. The other presented with a spontaneous bleed, which was fatal

it is possible to find a particular tree, here called a trunk, of a linear graph then certain simplifications can be effected in producing the fundamental circuit matrix and the fundamental cut-set matrix. The method is extended to a particular case where no trunk exists in the graph itself yet the graph can be split into sub-graphs each of which possesses a trunk.
