The purpose of this study is to investigate the compensatory correlation between knee and hindfoot in patients with rheumatoid arthritis (RA). This cross-sectional study included 218 patients (407 lower extremities). Radiographs of the hindfoot and full-length posteroanterior hip-to-calcaneus standing radiographs were evaluated. The destruction of the hindfoot was evaluated using the Larsen gra...
Streptococcus mutans present in a man on a world wide basis (Birgitta Kohler & Douglas Bratthall 1976). High numbers in the mouth of Streptococcus mutans are associated with both high prevalence and a high incidence of dental caries. The Directorate of Oral Health Ministry of Health Republic of Indonesia declared 60 80 percent of school children between 4 14 years by age were suffering from den...
Recently Richard Stanley [3] initiated a study of the distribution of the length asn(w) of the longest alternating subsequence in a random permutation w from the symmetric group Sn. Among other things he found an explicit formula for the generating function (on n and k) for Pr (asn(w) ≤ k) and conjectured that the distribution, suitably centered and normalized, tended to a Gaussian with varianc...
We generalize to the p−Laplacian ∆p a spectral inequality proved by M.-T. Kohler-Jobin. As a particular case of such a generalization, we obtain a sharp lower bound on the first Dirichlet eigenvalue of ∆p of a set in terms of its p−torsional rigidity. The result is valid in every space dimension, for every 1 < p < ∞ and for every open set having finite measure. Moreover, it holds by replacing t...
Last week we reviewed the 1984 Nobel laureates in medicine: immunologists Niels K. Jerne, Georges J.F. Kohler, and C6sar Milstein. 1 In this week’s essay the prizewinners in physics and chemistry are discussed. The 1984 physics prize was shared by Carlo Rubbia, Harvard University and the European Center for Nuclear Research (CERN), Geneva, Switzerland, and Simon van der Meer, also of CERN. The ...
The retreat and collapse of Antarctic Peninsula ice shelves in tandem with a regional atmospheric warming has fueled speculation as to how these events may be related. Satellite radar altimeter measurements show that between 1992 and 2001 the Larsen Ice Shelf lowered by up to 0.27 +/- 0.11 meters per year. The lowering is explained by increased summer melt-water and the loss of basal ice throug...
TO THE EDITOR: The letter of Lundberg et al. (12) does not relate directly to any of the articles we published in this journal (1, 2, 6). Rather, the correspondents make a general point on the potential risks to athletes who might choose to supplement their diet with nitrate or (especially) nitrite salts with the purpose of reducing the O2 cost of exercise and enhancing exercise tolerance. This...
during each event are also indicated. June 1982 to June 1983 (intense event, 1 transect); August 1986 to July 1987 (medium, 7 transects); October 1991 to May 1992 (marginal intensity, 2 transects); October 1992 to October 1993 (marginal, 3 transects); April 1994 to June 1995 (marginal, 8 transects); and April 1997 to April 1998 (intense, 15 transects). 12. To test biases caused by undersampling...
