In a recent paper, Peláez and Ynduráin evaluate some of the low energy observables of ππ scattering and obtain flat disagreement with our earlier results. The authors work with unsubtracted dispersion relations, so that their results are very sensitive to the poorly known high energy behaviour of the scattering amplitude. Indeed, their calculations mainly illustrate the fact that the most impor...

Between 1948 and 1996, mean annual environmental parameters in the Arctic experienced a well-pronounced decadal variability with two basic circulation patterns: cyclonic and anticyclonic alternating at 5 to 7 year intervals. During cyclonic regimes, low sea-level atmospheric pressure (SLP) dominated over the Arctic Ocean driving sea ice and the upper ocean counterclockwise; the Arctic atmospher...

Wright (1912) described a method for filling ampoules based on the principle of first exhausting the air from the ampoules and then filling by atmospheric pressure. Since then many elaborate pieces of apparatus have been devised based on the same principle, but these are^ all expensive and not readily obtainable. The ^odification described below has the advantage that the apparatus required may...

While many surface foraging seabirds ingest plastic, the spatial overlap of these far-ranging predators with debris aggregations at-sea is poorly understood. We surveyed concurrent distributions of marine birds and debris along a 4400 km cruise track within a debris accumulation area in the North East Pacific Ocean using line and strip transect methods. Analysis of debris and bird distributions...

Based on epidemiologic methodology different factors related to suicide committed in Asturias (Spain) during 1983-1987 were analysed. The following factors were studied: age, sex, procedure of suicide, climate variables (atmospheric pressure, frequency of south-winds), seasons of the year and Moon phases in which suicides were committed. The incidence was 11.13/100,000. In respect to several fa...
