Males of many animals perform 'copulatory courtship' during copulation, but the possible reproductive significance of this behaviour has seldom been investigated. In some animals, including the spider Physocyclus globosus (Pholcidae), the female discards sperm during or immediately following some copulations. In this study, we determined which of several variables associated with copulation cor...

Few capitation arrangements vary premiums by a child's health characteristics, yielding an incentive to discriminate against children with predictably high expenditures from chronic diseases. In this article, we explore risk adjusters for the 35 percent of the variance in annual out-patient expenditure we find to be potentially predictable. Demographic factors such as age and gender only explai...

Landfill leachates are potential threats for environmental degradation. This study was conducted to determine the leachate quality, to identify the dominant pollutants and to evaluate the leachate pollution potential of an active and closed dumping ground of an uncontrolled municipal solid waste landfill site in Kolkata, India using leachate pollution index. The results of the physico-chemical ...

Kinin studies were performed in six patients with vasomotor dumping after gastric surgery and in six control patients who had had similar surgical procedures without subsequent dumping. Depletion of the precursor, kininogen, was found in all the patients with dumping and increased free plasma kinin activity in four after a 50-g carbohydrate meal which precipitated an attack. No significant chan...

In Asian developing countries, large amounts of municipal wastes are dumped daily in open dumping sites without proper management. This practice may cause several adverse environmental consequences and increased health risk to local communities. To elucidate contamination by persistent organic pollutants (POPs)--including dichloro-diphenyl-trichloroethane and its metabolites (DDTs), hexachloroc...

BACKGROUND The purposes of this paper were to examine whether patient dumping has occurred under the National Health Insurance and to explore hospital administrators' attitudes toward the practice of patient dumping in Taiwan. METHODS The study subjects were administrators in general hospitals that were accredited by the Taiwan Joint Commission on Hospital Accreditation as medical centers, re...

dumping (Walker et al., 1962; Howe, 1964; Silver et al., 1965; Zeitlin and Smith, 1966). In two patients raised free plasma kinins were not found during a dumping attack. This is probably due to loss of activity during collection of samples owing to the extremely short half-life of bradykinin in vivo (15 seconds). Our results support the findings of Zeitlin and Smith (1966) and provide further ...
