Let V be an n-dimensional vector space over GF(q) and for integers k > t > 0 let m,(n, k, t) denote the maximum possible number of subspaces in a t-intersecting family 9 of k-dimensional subspaces of V, i.e.

We study the existence of solutions to Bolza problems involving a special class of one dimensional, nonconvex integrals. These integrals describe the possibly singular, radial deformations of certain rubber-like materials called Blatz-Ko materials.

Fix integers k ≥ 3 and n ≥ 3k/2. Let F be a family of k-sets of an n-element set so that whenever A,B, C ∈ F satisfy |A ∪ B ∪ C| ≤ 2k, we have A ∩ B ∩ C 6= ∅. We prove that |F| ≤ (n−1 k−1 ) with equality only when ⋂ F∈F F 6= ∅. This settles a conjecture of Frankl and Füredi [2], who proved the result for n ≥ k + 3k.

A 13-year-old girl presented with proteinuria and acute kidney failure. She was born at full term via cesarean delivery (due to nuchal cord), but there were no other prenatal or perinatal complications. In early childhood the patient had two hospitalizations at ages 4.5 and 9 years, respectively, the latter for pneumonia. She had no history of symptoms of kidney disease. She came to the hospita...

The Nephrology Quiz and Questionnaire (NQ&Q) remains an extremely popular session for attendees of the Annual Meeting of the American Society of Nephrology. As in past years, the conference hall of the 2013 meeting was overflowing with interested audience members. Topics covered by expert discussants included electrolyte and acid-base disorders, glomerular disease, ESRD/dialysis, and transplant...

Presentation of the Nephrology Quiz and Questionnaire (NQQ) has become an annual "tradition" at the meetings of the American Society of Nephrology. It is a very popular session judged by consistently large attendance. Members of the audience test their knowledge and judgment on a series of case-oriented questions prepared and discussed by experts. They can also compare their answers in real tim...
