ABSTRACT. A promising technique for recognition of early stages of cultural eutrophication relies on determining production and respiration in streams. The most successful and most widely used method of estimating production of a segment of a stream is the upstream-downstream, diurnal curve method introduced by Odum [1956]. This technique is equivalent to obtaining an approximate solution to the oxygen balance equation. We report here an exact solution of the balance equation as a method for calculating primary production. Data presented by Owens [1966] are analyzed; effects of depth and oxygen saturation are studied. A major advantage of the method described here is that continuous temporal variation of net production may be rigorously handled. The method is shown to be well suited to our ultimate goal of studying energy budgets of streams, and thereby the eutrophication process. 相似文献

The U. S. Nuclear Regulatory Commission has established a Working Group to evaluate methods for improving control of devices containing radioactivity in industry. These devices include radiography equipment and moisture/density gauges. The Working Group was the result of a number of incidents in which these devices were inadvertently shipped to scrap dealers and steel recycling facilities. The resulting release of radioactivity when the devices were processed has cost millions of dollars to clean up. This article discusses the Working Group's conclusions and the potential impact of these conclusions on the remediation industry. It also makes recommendations for both current and prospective owners of devices containing radioactivity on how to prepare for regulatory changes likely to occur as a result of the Working Group's conclusions. 相似文献

Since the first issue in 1977, Disasters has been one of the pre-eminent refereed journals on the study and reporting of disasters. This article reviews 703 articles and reports in the journal through 1996 to provide a snapshot of the nature of the journal throughout 20 years of publication. The results indicate the most common contributions: first, were research articles by authors from the North Atlantic; second, most often dealt with natural disaster relief or impact; and third, most frequently focused on Africa. These generalisations, however, do not reflect attention paid to food-related and political disasters and greatly understate the broad diversity of material presented in the journal. To improve the topical and geographic coverage of Disasters probably requires a proactive effort to close gaps in the journal's coverage of disasters. 相似文献

Summary Males and females of the seed bug, Neacoryphus bicrucis Say, were individually numbered in the field in southeastern Georgia (USA) and census taken daily for 6 weeks. Variation in male mating efficiency (ME = no. copulations/no. sightings) exceeded that in females and was significantly greater than that generated by a null model. Lifetime copulatory success, estimated as the product of ME and longevity, ranged from 0 to 41, with ME accounting for over 88% of the variation. Lifetime reproductive success (LRS), estimated as the product of ME, longevity, and clutch size, ranged from 0 to 898. Among males copulating at least once, ME accounted for over 40% of the variation in LRS, while longevity alone or in combination with clutch size accounted for 21% and 46%, respectively, of the variation in LRS. Failure of some males (26%) to copulate contributed 38% of the total variation in LRS. Thus, among males surviving to adulthood, sexual selection pressure arising from variation in ME is approximately as strong a force for phenotypic change as is natural selection pressure arising from variation in longevity. 相似文献

Background
Disease severity is important when considering genes for inclusion on reproductive expanded carrier screening (ECS) panels. We applied a validated and previously published algorithm that classifies diseases into four severity categories (mild, moderate, severe, and profound) to 176 genes screened by ECS. Disease traits defining severity categories in the algorithm were then mapped to four severity-related ECS panel design criteria cited by the American College of Obstetricians and Gynecologists (ACOG).Methods
Eight genetic counselors (GCs) and four medical geneticists (MDs) applied the severity algorithm to subsets of 176 genes. MDs and GCs then determined by group consensus how each of these disease traits mapped to ACOG severity criteria, enabling determination of the number of ACOG severity criteria met by each gene.Results
Upon consensus GC and MD application of the severity algorithm, 68 (39%) genes were classified as profound, 71 (40%) as severe, 36 (20%) as moderate, and one (1%) as mild. After mapping of disease traits to ACOG severity criteria, 170 out of 176 genes (96.6%) were found to meet at least one of the four criteria, 129 genes (73.3%) met at least two, 73 genes (41.5%) met at least three, and 17 genes (9.7%) met all four.Conclusion
This study classified the severity of a large set of Mendelian genes by collaborative clinical expert application of a trait-based algorithm. Further, it operationalized difficult to interpret ACOG severity criteria via mapping of disease traits, thereby promoting consistency of ACOG criteria interpretation.440.
