Recently Chase determined the maximum possible number of cliques size in a graph on vertices with given degree. Soon afterward, Chakraborti and Chen answered version this question which we ask that have edges fixed degree (without imposing any constraint vertices). In paper address these problems hypergraphs. For -graphs issues arise do not appear case. instance, for general can assign degrees ...

Problem. An abstract problem with “true/false”, rather than “violated”, instructions was employed. The specific problem and instructions were adapted from Platt and Griggs (1993b, p.596) and were as follows: Each of the boxes below represents a card lying on a table. Each one of the cards has a letter on one side and a number on the other side. Here is a rule: If a card has a vowel on its lette...

Human beings have used plants for the treatment of diverse ailments for thousands of years (Sofowara, 1982; Hill, 1989). According to the World Health Organization, most populations still rely on traditional medicines for their psychological and physical health requirements (Rabe and Van Stoden, 2000), since they cannot afford the products of Western pharmaceutical industries together with thei...

59 Introduction Since 1966 there have been reports in the literature suggesting that children with Down’s syndrome can achieve functional levels of literacy and that reading might accelerate speech and language acquisition (Duffen, 1976; Orme, Fisher & Griggs, 1966; Rhodes, Gooch, Siegelman, Behrns & Metzger, 1969; Saunders & Collins, 1972). All these authors used case study evidence to argue f...

Given a graded poset P , consider a chain decomposition C of P . If |C1| ≤ |C2| implies that the set of the ranks of elements in C1 is a subset of the ranks of elements in C2 for any chains C1, C2 ∈ C, then we say C is a nested chain decomposition (or nesting, for short) of P , and P is said to be nested. In 1970s, Griggs conjectured that every normalized matching rank-unimodal poset is nested....

• The effects of temperature on the development of rigor mortis in cardiac muscle have never been investigated systematically. Brecher and Kissen found that pressure-volume characteristics of non-beating, submerged dog ventricles remained constant for at least 30 minutes following circulatory arrest at 35°C. Using similar methods, Griggs et al. found this period to be approximately 80 minutes a...

Editors’ Note: Commenting on “The magnetic apraxia of Denny-Brown,” Dr. Hassan points out that magnetic apraxia is related to frontal lobe lesion and not parietal lobe dysfunction as suggested in the text. Dr. Peluso, author of the Video NeuroImage, acknowledges the mistake and a correction appears on page 1483. In response to “Mechanisms of memory impairment in epilepsy depend on age at diseas...
