The detour order (of a vertex v) of a graph G is the order of a longest path (beginning at v). The detour sequence of G is a sequence consisting of the detour orders of its vertices. A graph is called a detour graph if its detour sequence is constant. The detour deficiency of a graph G is the difference between the order of G and its detour order. Homogeneously traceable graphs are therefore de...

background: glucose-6-phosphate dehydrogenase (g6pd) deficiency is the most common enzyme disorder in human. the aim of this study was to determine the prevalence of g6pd deficiency among children and evaluate its association with abo/rh blood groups.   method: blood samples of 3401 asymptomatic children were analyzed and compared with 317 children who were admitted to hospital because of hemol...

The dynamics of complex isothermal reactors arc studied in general terms with special focus on connections between reaction network structure and the capacity of the corresponding differential equations to admit unstable behavior. As in some earlier work, the principal results rely on a classification of reaction networks by means of an easily computed non-negative integer index called the defi...

the purpose of this study was to determine the effects of feeding iron-deficient diet during pregnancy and lactation on maternal rats. a total number of 64 rats were divided into 4 groups (pregnant), (non pregnant), (lactating) and (non lactating) with 16 animals in each group. parameters used to evaluate the effects of dietary iron deficiency on the maternal animals were: iron contents of live...

objective: the purpose of the current research is to determine the impact of play therapy on academic achievement of students with mental deficiency of khorramabad exceptional elementary school. method: it was a pre-test, post-test study design. 60 students were selected and according to their mental deficiency characteristics were assigned to either experimental or control group. each group co...

Acknowledgments First and foremost, I would like to thank my advisors, Steve Altschuler and Lani Wu. In addition to suggesting to me a rich and interesting thesis topic, and advising me as I wrote about it, Steve and Lani have deeply informed my view of what it is to be a mathematician and a scientist. My work with them, both during the summer and on this thesis, has influenced my academic and ...
