In 1932 Franz Kramer (1887-1967) and Hans Pollnow (1902-43) described a hyperkinetic syndrome in children. Basically the symptoms described coincide with what is nowadays regarded as Attention Deficit Hyperactivity Disorder (ADHD) or Hyperkinetic syndrome. The authors of the study thus went down in the history of child and adolescent psychiatry with their eponymous Kramer-Pollnow syndrome, and ...

Variation in human DNA sequences account for a significant amount of genetic risk factors for common disease such as hypertension, diabetes, Alzheimer’s disease, and cancer. Identifying the human sequence variation that makes up the genetic basis of common disease will have a tremendous impact on medicine in many ways. Recent efforts to identify these genetic factors through large scale associa...

Kramer-Mesner matrices have been used as a powerful tool to construct t-designs. In this paper we construct Kramer-Mesner matrices for xed values of k and t in which the entries are polynomials in n the number of vertices of the underlying graph. From this we obtain an elementary proof that with a few exceptions S 2] n is a maximal subgroup of S (n 2) or A (n 2). We also show that there are onl...
